Why don't you just give in. Pt.5
Fem reader
18+, rough handling, fingering,
Pt.4
Riley
He groans loudly and kicks his leg out, kicking the front passenger seat of the taxi.
“Oi! Mate, pack it in otherwise I'm bootin’ you out. Can bloody well walk home.” The cabby driver snaps as he eyes him in the rear view mirror.
“Alright, alright, sorry mate.” Riley raises his hands to placate the driver. Relaxing back into his seat and crossing one leg over the other he stares out the window. The drive doesn't take long, the housing estate he resides in being closer to the town centre than the outskirts. The driver barely has time to pull the handbrake up before Riley chucks a few notes at him, barely wincing at the night time surcharge, before swiftly exiting the taxi and stalking up to his front door. Letting himself in, he shrugs off his jacket and shoes as in the small hallway before climbing the stairs and straight into the shower.
Standing under the hot spray he leans his forehead against the tile wall and shuts his eyes, though doing so turns into a big mistake. As soon as his lids meet it's like the lights go off in a cinema auditorium, images dance over the forefront of his mind of you and him. His nose trailing down the column of your neck as your back arches under his touch, his tongue tracing your areola before his teeth tug on your hardened nipple. Your laugh as he lazily kisses you when you wake, the sounds of rain outside as you both lay on opposite ends of his couch, legs entwined, while you both read. Coming up behind you as you make a cup of tea for the two of you, his hands resting on your hips and his mouth finds the soft skin of your neck, trailing up to your ear as he finally whispers those three little words. I love you. He nearly rips the handle off the valve as he turns the water off and steps out.
Not now, I can't think of you. Why do you fucking haunt me. It's been months and you clearly just wanted my cock.
Drying himself he dresses in a pair of sweatpants, forgoing boxers. He walks downstairs and into the kitchen, pouring himself a double bourbon he takes it through to the lounge. Parking out on the sofa he sits in the dark, downing the drink and pulling up his phone. He pauses, as he places the glass on the coffee table, hoping the moment gives him time to really think about what he's about to do, to stop himself.
“I'm too fuckin’ weak for my own good.” He mumbles, opening the locked folder in his photos app as he tortures himself further, scrolling through the hundreds of saved photos of you, of the two of you. Lights shine through the front window, almost blinding him and he glances up, frowning as a car uses his drive to turn. Blinking the bright dots away he realises someone is climbing out, it's a taxi. That someone is walking up to his front door. That someone looked like they're wearing a hoodie and jeans shorts. It's like the air is stolen from the room, his heart races as he realises it's you. Like a prayer he'd never had the courage to utter is answered, and there you are on his property.
It's like a dream, and he practically glides out the front room and back into the small hallway to his front door, opening it just as you raise your hand to knock. Your eyes are slightly glazed, your hair tousled. Not styled but clearly raked through as you would normally do when you're nervous.
“Hey.” A simple statement. Breathy, soft like a whisper almost.
“Why are you here?” His jaw set, eyes narrowing.
“I… miss you, I wanted to-” You're nervous, your fingers play with the zipper of your hoodie.
“I'm not your fucking booty call, not the person you come to for a quickie.” He practically barks, fuck his thoughts tonight. Fuck that weak moment he'd allowed himself as he revisited the good times. Closing the door in your face he goes to turn but the door doesn't shut all the way, it stops abruptly. Glancing down he notices your foot in the door frame.
“I love you.” It rushes out your mouth, as if the words themselves were living entities you couldn't control. Your fingers curl around the door frame as you try to push it further, to see him.
He stands there, his heart racing. I love you. It echoes in his mind. Those words he so longed to hear all those months ago. A year ago. Why has it taken so long? Why now? Instead of joy, anger rises up. The door flies open as he pulls it roughly, grabbing you by the fabric of your clothing and hauling in you. He catches you as you stumble, kicking the door shut being you and enveloping you. Left hand gliding up your nape to your hairline as his fingers comb through and tugging you to him, right hand wrapping around your lower back and his mouth crashes into yours. He groans, pulling you hard against him as the kiss is fierce and all encompassing as he pours all his heartbreak into it. He feels your hands wrap around him, your right hooked around his neck and your left sliding across his rib cage and resting between his shoulder blades. You taste sweet, not just the alcohol. But his favourite taste, barring one other.
The anger catches up to him and he stumbles forward with you, you almost fall onto the carpeted stairs before he pulls you up and rights you. Pulling away he draws in a lung full of air. His chest heaving with how heavy the kiss was.
“You love me? You?” It's almost a growl, how deep and low his voice is. He doesn't give you time to answer before he spins you in place, your back now to him. He yanks your shorts and underwear down in one fell swoop, they fall to your ankles, before his left hand wraps around your jaw and the right rests against your navel.
“You love me?” His grip on your jaw tightens as he roughly turns you to face him over your shoulder. His hand glides down to your pussy, sliding his finger between your lips he feels how slick you are. Only then does he take notice of your ragged breaths, how your chest heaves. It's like liquid fire erupts in his belly, spreading low and he feels his cock harden almost painfully.
“I do I'm sorry-”
“You're sorry? Fucking what? You fucking haunt me, made me fall in love with you, chew me up and then spit me out.” He pushes you forward onto the stairs, planting his left hand between your shoulder blades, the fingers of his right find your pussy again, he doesn't waste any time before pushing one in. He feels you go rigid before a whimper falls from your mouth. He finds that sweet spot right away, almost like no time has passed, and he curls his finger. You moan and arch your back in response.
“Oh you like that?” He keeps his voice level. Pushing a second in he does the same, curling and then pumping them in and out of you slowly.
“Jesus fuck Simon…” it comes out shaky, your fingers curling and uncurling against the edge of the step your face rests against.
“So tight, so wet, love.” He leans forward, nose in your hair, smelling you before his mouth finds the lobe of your ear.
“You think-” he fingers work inside you, curling and pumping into you as he feels you tighten around him “-you can just come in here, to my home.” He pauses as your body starts to shake, he knows you're close. “In the middle of the fucking night. And tell me that? What fucking use is it now?” Just as you let go he pulls out of you and slaps your ass hard. You're a mess, shaking on his stairs under him.
“Please Simon…” you murmur, he can hear the disappointment in your voice. Are you disappointed because he withheld your orgasm? Or because you can't suck up to him?
Bringing his fingers to his mouth he sucks your taste off of him, stifling a groan at the taste, his favourite taste. It's been too long. But he's too fucking angry with you. Keeping his left hand between your shoulder blades his right slides up and wraps around your hair, fisting it as he yanks you backwards against him. “Why should I believe you? You're a fucking coward, only ever here for my cock. Never said a word to me this whole time, and now you turn up in the middle of the fucking night.” He feels your back against his chest, even through your clothes he can feel the rapid fire beat of your heart.
“Si… just please. Listen to me. Just… give in this one time. Give me a chance.” you murmur, he feels your head turn against his, like you're searching for his eyes over your shoulder but it's too dark, and you're both so so close.

I'm still not feeling great, but I really needed groceries. So I forced myself to go last night, which was a really bad idea considering I hadn't recovered from post-exertional malaise as it was.
But I didn't have much food due to stalling for so long. I know I could do delivery or have someone pick stuff up, but I really need to walk around and pick things out. If I am not in the mood for something I won't eat it. I can be picky that way. And then it spoils and I have to throw it out. It's just better if I go to the store and find things that my brain has a craving for.
It just seems like whenever I have the least energy and I try to do a short, simple trip out of the house, I have all of these mini-adventures that make it not as short and simple.
In this case, I didn't even make it out of my driveway before the adventures began. I got in the car there was a warning my tire pressure was low. And usually it isn't that bad and I can just fill up the tires when I have more energy. But one tire was extremely low, so I didn't want to chance it.
I wish I knew why my tires lose air so fast. Seems like I fill them every week or two. I read it could be bad valve stems. But like, on all the tires? I'll save that mystery for another day.
Unfortunately putting air in my tires is just about the hardest task for me specifically. Even if I sit on a stool, I have to bend down in a way that pushes my belly against my lungs. I run out of breath very quickly and so I have to go up and down many times to finish filling the tire. By the end of filling all 4 tires, I was sweating, exhausted, out of breath, light headed, and nauseous.
I really need to find a better way to fill my tires. I could try sitting on the ground, but standing up from the ground is not always easy for me and I'd have to do it 4 times.
I wonder if there is a place I can tip someone to do it.
I digress.
I make it to Sam's and I am struggling before even walking in the store. And they have gigantic shopping carts that take much more energy to push around. Schnucks has these little baby carts that are great for when you need a few items. I guess Sam's assumes if you are going to a bulk store you are going to buy in bulk.
I get my sushi and my brownie bites and everything else and head towards checkout. I have a bit too much stuff for self checkout to make sense, so I get in line.
On one side of me was a guy who was impulse buying a 65" TV. Which is a really bad idea. You should never buy any electronics without researching it first. (Or ask me. Everyone should always ask me before buying technological items.) He was buying a TV that was made to be thin. And if he needed a super thin TV, and he couldn't afford an OLED, it was an okay choice. But for the same price he could get a thicker TV with much better image quality. There was a part of me that wanted to take him back over to the TV aisle and help him make a better decision. But my anxiety thought of about 30 ways that could have backfired and I was barely standing.
And then there was this cart in front of me...
Tumblr media
Seriously?
Is there a midwestern hurricane headed this way or something?
I don't even understand how they did this.
This isn't Tetris. This is... overstuffing a turkey.
I'm a little worried about those eggs too.
Thankfully a new lane opened up and I didn't have to wait 30 minutes for them to figure out how to deal with that.
I did try to use my amazing Tetris skills to arrange my items so the bar code was visible for each one. (I probably could have done self checkout, I guess.) Last time the lady thanked me for making it so easy for her. So I was waiting for this lady to pull out her laser shootie price gun and start zapping my stuff.
But she unloaded everything in my cart onto the conveyor.
Tumblr media
My shopping cart Tetris skills went unnoticed and she had to do 3 times the work.
Then I get out to the parking lot and a bunch of carts are all blocking the disabled parking space for people with rear-loading wheelchairs.
Tumblr media
I tried to move some of them as I went by. I just didn't have the energy to put them all in the receptacle. But even if they are in the yellow zone, that is where they need to unload the wheelchair. I'm just so tired of people being inconsiderate like this.
And I also see a lot of disabled people without wheelchairs using this space. I suppose if it is the only one available, but this is such a great accommodation for wheelchair users. It is much safer to unload away from traffic. I would rather park in the back of the lot than take this option from someone.
Oh, and Schnucks has one of the disabled spots reserved for police and that makes me so mad too. They can double park if there is an emergency. I never see a cop car in that space and so many people could be using that.
Sorry, after pushing my dad around for a year I have become very sensitive to this.
I really wanted to drive straight home, but I still needed some soup and black cherry soda from Schnucks. I probably should have gone back a different day, but sometimes a different day isn't for weeks. So I just got it all done at once. Plus I really wanted to try that Vess black cherry.
Sorry, RefresCoVesScnhucks™ Black Cherry Soda.
I've been pretty sore all day. And I'm still not prepared for the second house auction. And people are coming to pick stuff up from the first auction on Friday. The house is a mess again. Half the groceries aren't put away.
I'm going to need to pull my lantern battery out of the pocket dimension to charge myself back up.

Dragon Booster Notes: Misc. Anatomy
more dragon anatomy! this is a mix of "narrator" and regular voice so just bear with me
Respiration:
Tumblr media
[image ID: a semi-cartoony drawing of a quadrupedal, Canid-type dragon, lean and somewhat gangly. a simplistic respiratory system has been superimposed on the body. the "entry nostril" located on the dragon's forehead leads down the trachea in the throat, down to the "primary air sacs" located at the bottom of the ribcage. these sacs then empty into the "lungs" located towards the front of the ribcage. the lungs then empty into "secondary air sacs", located to the sides of the ribcage. these sacs connect by tubes to two sets of "exit nostrils" located to the bottom sides of the ribcage. end ID]
comparable to avians of the past, dragons display a complex system of air sacs to regulate air flow. air first enters the entry nostril located on the forehead, flows down through the trachea, and into the primary air sacs towards the bottom of the ribcage. this air then flows into the lungs for gas exchange, then into the secondary air sacs towards the sides of the ribcage. finally, this air exits the secondary air sacs through two sets of exit nostrils on either side of the bottom of the ribcage.
without the need to exhale back through the trachea, as with most other vertebrates, dragons can maintain a constant flow of air through the lungs without any breaks. this results in arguably the most efficient respiratory system in the modern day. most researchers agree that this is one of the only reasons dragons can race at such extreme speeds and compete in such feats of strength.
but gas exchange is not the only function of this system-- the other reason dragons can race so effectively is due to the heat regulation of this system. both sets of air sacs (but particularly the secondary air sacs and exit nostril tubes) are lined with millions of capillaries on their inner walls, allowing blood to flow close to the surface of the thin tissue. air passing through these sacs picks up excess heat from the blood and releases it on the final exhale out of the body. thus, dragons effectively prevent overheating from their extreme racing habits.
I must admit that this entire respiratory system was inspired by a little one-off scene in s1 ep 3 where Beau releases "steam" after overheating on the lava track.
Tumblr media
[image ID: a screencap from the show Dragon Booster, showing Artha riding Beau. Beau is a quadrupedal, "Canid-type" dragon with a blue/red color scheme at the moment. he's hunched over in exhaustion, with steam being released from a few implied sets of valves along his spine. end ID]
I just think it’s fun~
Heat Pits:
Tumblr media
[image ID: a semi-cartoony dragon head with a dull red color. the dragon has a long, angular head, with flat fins on either side of the skull, and a large chin that points far forward. a few small holes sit to either side of the snout above the mouth, and towards the back of the jaw under the mouth. diagrams of the "heat pit organs" have been superimposed in these areas, looking like two sets of small sacs attaching to their respective holes by thin tubes. end ID]
dragons primarily use their heat pits to sense environmental heat and better thermoregulate using their respiratory system. dragons certainly can use their pits to aid in tracking and hunting prey (in fact, certain colors have emphasized pits for that very reason), but that is not their primary function.
Audial Fins:
Tumblr media
[image ID: the same red headshot as before, but with different labeling/diagrams. instead, the flat fins on either side of the skull are labeled "audial fins". these fins have a couple rows of half-circles running down the length like grills, curved inwards towards the face. these lines are labeled "sensory lines". end ID]
audial fins function somewhat like fish lateral lines, sensing air disturbances and translating that to audio cues. they also seem to sense Draconium in some yet-defined way...
Hips:
Tumblr media
[image ID: a simple scientific diagram showing two different, bipedal dinosaur skeletals. the top diagram is saurischian, with hips whose long pubis points forwards from the ilium, while the long ischium points back from the ilium. the bottom diagram is ornithischian, with hips whose long ischium and pubis lay flat together, both pointed back from the ilium towards the rear of the animal. end ID]
I've decided to give all dragons ornithischian hips (bottom diagram, with the projection pointing just backwards). no specific reason for it, I just needed to establish that.
Teeth:
Tumblr media
[image ID: a side-view of a dragon head with a purple base color. it’s similar in shape to the previous dragon heads, and the mouth is open to show off a set of thick, chunky teeth, looking more like scale-plates than teeth. the top teeth have a sort of wave shape, with a pointed front tip that flows into a short bump towards the back. the bottom teeth have a short front point with a taller back point. a set of longer/pointed teeth at the tip of the top and bottom jaws serve as the canines. end ID]
I like the idea of the teeth looking like big hunks of scale-- I’m picturing Dunkleosteus, here. it’d also be cool if the teeth matched the scale palette in some way, whether the main or accents colors.
Chins and Lips:
Tumblr media
[image ID: the same red headshot as before, but with different labeling/diagrams. here, the entire chin/bottom jaw and lips have been colored a dull green. a nearby label reads, "general region of tactile sensitivity". end ID]
dragons are highly social, tactile animals, and will often communicate with one another and their riders through touch. the chin and lips are a primary area of contact, far more sensitive to touch than other parts of the body. dragons will typically rub/knock their chins together, or lip at one another to establish and strengthen emotional bonds. this behavior extends to their riders as well, and lipping is a common form of communication from dragon to rider. humans may reciprocate affection by giving their dragons a good chin rub in return.

For a writing prompt I’ve had this idea of like an outsider POV of Kirigan’s Grisha seeing him be affected with merzost and are just talking with each other like “is he ok???”
Like maybe Vladim goes to deliver medicine and before he opens the door he just hears Aleksander coughing his lungs out. Or someone accidentally sees Aleksander with a healer as he’s dry heaving in a bucket and the healer shoos them away. Perhaps someone sees him outside at night cause he couldn��t sleep with his headaches. Just like little things that make them all raise an eyebrow at each other. Maybe it gets to a point where he just doesn’t wake up and they’re all like “is he dead??!!” but then a healer finds out that he’s fine he was just really sleep deprived and to the others they’re like “ahh just let him rest”
Not quite what you've suggested, but I think you will like it:
AO3 version
Price of Safety
Grisha don’t get sick. Everyone knew that.
And Healers knew that it was not that simple.
Plagues had no power over Grisha. Sicknesses that spread left Grisha unharmed.
Grisha only fell into sickness when they were weak. At least, that was what Elinor had always seen.
Wounds could get infected, but even that was rare.
No, most Grisha sickness came from denial. At the Little Palace, they called it suppression wasting, or just the wasting sickness. A body eating itself alive, breaking down because it lacked the power of the Making.
Elinor had seen it many times, working with other Fjerdan refugees. Elinor had lived it herself for most of her life.
She never imagined there was a way for Grisha power, for that euphoric feeling, like coming for air after almost drowning, to cause sickness. It didn’t make sense.
She had heard of Merzost, of course. Of the power that created the Fold and killed its maker. But it seemed like a fairytale. A scary story to make children behave.
And yet.
And yet.
Every victory, every group of rescued Grisha, he stood there, watching, looking pale, the aura of power replaced with the cold wrongness.
There was no wound to be healed. No single source of the illness except the power itself, the energy that protected them all but ripped him to shreds as it did so.
She remembered one of her first nights at the base. She had the night shift, taking care of the few injured they had.
“Do you need something?” she had asked.
He asked about the injured.
“I’m not sure there’s much more that can be done for them.” she had said. She was the only fully trained Healer there, at the time. And there were some things Heartrenders and Tailors couldn’t help her with.
“Would amplification help?”
She wasn’t sure what he meant, at first. Then he offered her his hand.
She was able to help the injured. But even with the power, she couldn’t help him. She only took more.
She worried what would happen once there was nothing more to take.
***
Vatra walked through the corridor, hands outstretched. Kirill followed her, hand on the wall.
“There’s a little bit here.” she stopped.
“Let me check.” he nodded, following the trailing his fingers along the wall, still. “The pipe seems okay.”
A cough echoed from behind the door to the master bedroom, where the general had taken up residence. The two of them looked at each other.
“Is he okay?” Kirill asked, scanning the wall lamp. “The valve on this one is leaking a little. It’s a quick fix.”
Vatra walked to open a window, letting the gas vent out. “The Healers think it’s the monsters. They’re Merzost.”
“Is he going to be okay?”
Vatra shrugged her shoulders. “Focus on fixing the lamp so he doesn’t get blown up. There’s nothing more we can do.”
“I don’t like that.” Kirill frowned, but he focused on valve, sealing the cracks. “It looks like the knob needs to get oiled. Then, there won’t be so much force needed and it won’t break again.”
“I’m pretty sure that’s your job to keep track of.”
“I’m just thinking out loud, Varvara.”
“Saints, chill.” she rolled her eyes. “I know.”
“Do you have something I could make a note on? So that people leave it alone until I get to it?”
“I don’t make a habit of carrying flammable things on me unnecessarily.”
“Right.” he sighed and forced the paint in the wallpaper to form the necessary message. “Actually… I have an idea.”
***
She slipped soundlessly into the room.
“Genya? Do you need something?” he asked her. He stood by the map, presumably thinking of the best road to take for the night’s raid. “How is your arm?”
Genya run her hand over the recently torn fabric. There were no signs of her clothes anymore, though the wound still lingered.
“As good as it can be.” she said. “Fruzsi asked me to talk to you. On behalf of her and the rest of the strike team for tonight.”
“If they want to stay and sleep, I’ll let them. They could have just come and asked. The camp is small, it will not be much work.”
“Actually, that’s what they wanted to ask you to do.” she smiled a little. “And they sent me because I’m the only one crazy enough to suggest it and the only one you might listen to.”
“I’m not sure I understand.”
“They want to go alone. You’ve been stretching yourself thin to save us and we can all see what it’s doing. We’re worried about you.”
“It’s not as bad as it looks.”
“Forgive me for not believing that.” she shook her head.
“This is the safest way.”
“And what of when it kills you?” she raised her voice. “Will we be safe then?” He looked at her curiously. She rarely allowed herself to express her anger. “There’s enough of us that we can handle the regular attacks. If that power is killing you, it should be the last resort.”
“Sometimes, we need to suffer to change things. You know that yourself.”
“I’m starting to think you’re just a masochist.” Genya muttered. “You’ve just said it’s going to be easy. They know what they’re doing. Give them a chance.” she stepped closer. “We’re soldiers. This is our fight, too. You don’t have to do everything on your own.”
“It is worth a try.” he admitted.
“We’ve all seen what happens when we fail, Moi Soverennyi. And we’re not going to let it happen.”

I bet youve been asked this many times but where are the lungs, like are they double lunged up or is it in one of the two bodies and if its just one whats the space used for instead?... And now that i think about it most of the other organs would be double too this is honestly the first time i realised that...
Im confused
you are actually the first person to ask this, but boy am i ready to answer it. i think about centaur anatomy so fucking much you would not believe.
disclaimer - i know nothing about biology and did no research past google images im just vibing here. i try to make things logical but am not really fussed about it being strictly viable.
so they are, in fact, double-lunged (or quad-lunged? 2 sets of 2, 4 total). they're both located and sized pretty much how you'd expect, one smaller pair in the upper torso (human half) and one larger in the lower torso/barrel (horse half)
Tumblr media
the one thing these two pairs absolutely cannot do is alternate. one cannot be exhaling while the other inhales. but if a random fun fact i picked up from researching war horse puppetry is correct, horse lungs are three times larger than human lungs. so, while both sets inhale and exhale at the same time, most of the time the lower lungs will be expanding and contracting three times as fast as the upper ones to stay in sync.
so, what is the advantage of having that many lungs? well, the main function of the system is allowing effective verbal communication while on the move.
as someone without a spare set of lungs, you may have noticed that talking while running, or even just walking if youre particularly worn out, is a bit tricky. centaurs, at least how i write them, evolved to be constantly moving through large territories of foraging and hunting grounds while also making use of complex verbal communication, so they need a way around this issue.
most of the time, a centaur's vocal chords are vibrated soley by air exhaled by the upper lungs. when they speak, they are able to increase the speed of exhalation of the upper lungs relative to the lower to do so. this means they exchange less gass through the upper lungs, but the lower are unaffected. so if they need to communicate while on the move, they can essentially use the air in the upper lungs to speak while the lower go on circulating oxygen and carbon dioxide as normal, meaning it's harder for them to get out of breath. that's not to say they can hold full converstations at a gallop no problem, though. theres still limits.
Tumblr media
they can, if they need to, use the lower lungs to vibrate the vocal chords too via opening a valve in the throat. this allows them to make much louder sounds, mostly for long-distance calls to herdmates. they're usually wordless noises with simple meanings, harder to misinterpret over distance.
Tumblr media
they also have two hearts, in the regular heart places.
Tumblr media
having two ensures that enough blood makes it around both the big ol legs and the big ol brain. the two systems are linked, otherwise the brain wouldn't be able to benefit from the double respitory system, which i dont think would end too well for the centaur
so thats the cardiovascular and respiratory system of a centaur, to my understanding. ill probably make similar posts on the rest in future i love speculative biology shit

Valve Series Timeline
Somebody asked me why I don't do a post about all the connections between half-life and portal and all the back story there. The theory being that a lot of other theorists don't get it right.
And they weren't wrong. The problem with most theorists is that they stop at a surface level, where I go real deep into the lore and pick out all sorts of details and connections. Sometimes even to a degree that isn't fully supported by on game detail.
But here's the thing with the half-life series. And valve games in general;
The story and background lore is already plotted out to a near dizzying degree. There is rarely a loose end between games.
Me doing a segment on half-life and portal would just be connected end to end on a path already laid out by valve. It would be incredibly boring. I would have suspected that's why other theorists don't do it. But I'm beginning to think it's just that people don't think about things to the degree I do.
Note I said: "To the Degree I do" not better, not worse. Just not the same way. But probably because I'm more of a completionist.
Anyway to prove my point, I'll simply point out the first Half-Life multiplayer expansion (Developed by Gearbox Studios): Half-Life: Decay
The bonus mission follows a couple of vortigaunts: R-4913 and X-8973. In the game, both share the same character model. I heavily suspect that only R4 was actually modelled, it being a kind of throwaway bonus mission, and the fact that valve only has "R-4913" written in an air duct along with "Code Green". The game Half-Life: Uplink does the same, only referencing R-4913 and *not* X-8973
Now. Let's look at Portal 2's Multiplayer Heros: Atlas and Peabody. Compare ATLAS and R4913 visually. They have the same basic body type. You could boil this down to a simple throwback. But Valve doesn't do things half-baked. Except for a third game. This is intentional on the devs part. All the way down to how they're "just a couple of random a*, but vitally important grunts"
The vortigaunts are sent on a viral suicide mission by the Nihilanth. GlaDOS is a Nihilistic artificial intelligence who sends the same two on a suicide mission, which is vitally important for her plans.
These two are essentially Seal Team 6.
To take things a step further if your rearrange the letters in ATLAS, LAATS, matches up with a kind of l33t-speak interpretation, which was appropriate for the year that Half-Life came out. And Valve and Gearbox being full of a bunch of dumb Internet nerds, makes this incredibly far-fetched interpretation, not so far-fetched. (Considering Ls and Rs is still a thing we do to this day thanks to all the languages that roll them together.)
The same for PEA-BODY or X-8973. I don't know how X converts to P yet... But given enough time and effort I could learn..but it'll probably be easier to ask gearbox themselves.
The implications of this are important; it means that both Vortigaunts and Humans (specifically: dying people [or wounded warriors]) were placed into AI like Caroline into GlaDOS.
This is the exact reason why some test subjects didn't have to sign a waiver whenever you see those waivers lying around.
And, if I'm not mistaken: Why Chell was uploaded in the first place...

Hydraulic Manifold valve manufacturer in india by hydrofittings

20k Leagues under the sea, Jules Verne
CHAPTER XV
A WALK ON THE BOTTOM OF THE SEA
This cell was, to speak correctly, the arsenal and wardrobe of the Nautilus. A dozen diving apparatuses hung from the partition, waiting our use.
Ned Land, on seeing them, showed evident repugnance to dress himself in one.
“But, my worthy Ned, the forests of the Island of Crespo are nothing but submarine forests.”
“Good!” said the disappointed harpooner, who saw his dreams of fresh meat fade away. “And you, M. Aronnax, are you going to dress yourself in those clothes?”
“There is no alternative, Master Ned.”
“As you please, sir,” replied the harpooner, shrugging his shoulders; “but as for me, unless I am forced, I will never get into one.”
“No one will force you, Master Ned,” said Captain Nemo.
“Is Conseil going to risk it?” asked Ned.
“I follow my master wherever he goes,” replied Conseil.
At the Captain’s call two of the ship’s crew came to help us to dress in these heavy and impervious clothes, made of india-rubber without seam, and constructed expressly to resist considerable pressure. One would have thought it a suit of armour, both supple and resisting. This suit formed trousers and waistcoat. The trousers were finished off with thick boots, weighted with heavy leaden soles. The texture of the waistcoat was held together by bands of copper, which crossed the chest, protecting it from the great pressure of the water, and leaving the lungs free to act; the sleeves ended in gloves, which in no way restrained the movement of the hands. There was a vast difference noticeable between these consummate apparatuses and the old cork breastplates, jackets, and other contrivances in vogue during the eighteenth century.
Captain Nemo and one of his companions (a sort of Hercules, who must have possessed great strength), Conseil, and myself, were soon enveloped in the dresses. There remained nothing more to be done but to enclose our heads in the metal box. But before proceeding to this operation, I asked the Captain’s permission to examine the guns we were to carry.
One of the Nautilus men gave me a simple gun, the butt end of which, made of steel, hollow in the centre, was rather large. It served as a reservoir for compressed air, which a valve, worked by a spring, allowed to escape into a metal tube. A box of projectiles, in a groove in the thickness of the butt end, contained about twenty of these electric balls, which, by means of a spring, were forced into the barrel of the gun. As soon as one shot was fired, another was ready.
“Captain Nemo,” said I, “this arm is perfect, and easily handled: I only ask to be allowed to try it. But how shall we gain the bottom of the sea?”
“At this moment, Professor, the Nautilus is stranded in five fathoms, and we have nothing to do but to start.”
“But how shall we get off?”
“You shall see.”
Captain Nemo thrust his head into the helmet, Conseil and I did the same, not without hearing an ironical “Good sport!” from the Canadian. The upper part of our dress terminated in a copper collar upon which was screwed the metal helmet. Three holes, protected by thick glass, allowed us to see in all directions, by simply turning our head in the interior of the head-dress. As soon as it was in position, the Rouquayrol apparatus on our backs began to act; and, for my part, I could breathe with ease.
With the Ruhmkorff lamp hanging from my belt, and the gun in my hand, I was ready to set out. But to speak the truth, imprisoned in these heavy garments, and glued to the deck by my leaden soles, it was impossible for me to take a step.
Tumblr media
I was ready to set out
But this state of things was provided for. I felt myself being pushed into a little room contiguous to the wardrobe-room. My companions followed, towed along in the same way. I heard a water-tight door, furnished with stopper-plates, close upon us, and we were wrapped in profound darkness.
After some minutes, a loud hissing was heard. I felt the cold mount from my feet to my chest. Evidently from some part of the vessel they had, by means of a tap, given entrance to the water, which was invading us, and with which the room was soon filled. A second door cut in the side of the Nautilus then opened. We saw a faint light. In another instant our feet trod the bottom of the sea.
And now, how can I retrace the impression left upon me by that walk under the waters? Words are impotent to relate such wonders! Captain Nemo walked in front, his companion followed some steps behind. Conseil and I remained near each other, as if an exchange of words had been possible through our metallic cases. I no longer felt the weight of my clothing, or of my shoes, of my reservoir of air, or my thick helmet, in the midst of which my head rattled like an almond in its shell.
The light, which lit the soil thirty feet below the surface of the ocean, astonished me by its power. The solar rays shone through the watery mass easily, and dissipated all colour, and I clearly distinguished objects at a distance of a hundred and fifty yards. Beyond that the tints darkened into fine gradations of ultramarine, and faded into vague obscurity. Truly this water which surrounded me was but another air denser than the terrestrial atmosphere, but almost as transparent. Above me was the calm surface of the sea.
We were walking on fine, even sand, not wrinkled, as on a flat shore, which retains the impression of the billows. This dazzling carpet, really a reflector, repelled the rays of the sun with wonderful intensity, which accounted for the vibration which penetrated every atom of liquid. Shall I be believed when I say that, at the depth of thirty feet, I could see as if I was in broad daylight?
For a quarter of an hour I trod on this sand, sown with the impalpable dust of shells. The hull of the Nautilus, resembling a long shoal, disappeared by degrees; but its lantern, when darkness should overtake us in the waters, would help to guide us on board by its distinct rays.
Soon forms of objects outlined in the distance were discernible. I recognised magnificent rocks, hung with a tapestry of zoophytes of the most beautiful kind, and I was at first struck by the peculiar effect of this medium.
It was then ten in the morning; the rays of the sun struck the surface of the waves at rather an oblique angle, and at the touch of their light, decomposed by refraction as through a prism, flowers, rocks, plants, shells, and polypi were shaded at the edges by the seven solar colours. It was marvellous, a feast for the eyes, this complication of coloured tints, a perfect kaleidoscope of green, yellow, orange, violet, indigo, and blue; in one word, the whole palette of an enthusiastic colourist! Why could I not communicate to Conseil the lively sensations which were mounting to my brain, and rival him in expressions of admiration? For aught I knew, Captain Nemo and his companion might be able to exchange thoughts by means of signs previously agreed upon. So, for want of better, I talked to myself; I declaimed in the copper box which covered my head, thereby expending more air in vain words than was perhaps expedient.
Various kinds of isis, clusters of pure tuft-coral, prickly fungi, and anemones formed a brilliant garden of flowers, enamelled with porphitĂŚ, decked with their collarettes of blue tentacles, sea-stars studding the sandy bottom, together with asterophytons like fine lace embroidered by the hands of naĂŻads, whose festoons were waved by the gentle undulations caused by our walk. It was a real grief to me to crush under my feet the brilliant specimens of molluscs which strewed the ground by thousands, of hammer-heads, donaciae (veritable bounding shells), of staircases, and red helmet-shells, angel-wings, and many others produced by this inexhaustible ocean. But we were bound to walk, so we went on, whilst above our heads waved shoals of physalides leaving their tentacles to float in their train, medusĂŚ whose umbrellas of opal or rose-pink, escalloped with a band of blue, sheltered us from the rays of the sun and fiery pelagiĂŚ, which, in the darkness, would have strewn our path with phosphorescent light.
All these wonders I saw in the space of a quarter of a mile, scarcely stopping, and following Captain Nemo, who beckoned me on by signs. Soon the nature of the soil changed; to the sandy plain succeeded an extent of slimy mud, which the Americans call “ooze,” composed of equal parts of silicious and calcareous shells. We then travelled over a plain of sea-weed of wild and luxuriant vegetation. This sward was of close texture, and soft to the feet, and rivalled the softest carpet woven by the hand of man. But whilst verdure was spread at our feet, it did not abandon our heads. A light network of marine plants, of that inexhaustible family of sea-weeds of which more than two thousand kinds are known, grew on the surface of the water. I saw long ribbons of fucus floating, some globular, others tuberous; laurenciæ and cladostephi of most delicate foliage, and some rhodomeniæ palmatæ, resembling the fan of a cactus. I noticed that the green plants kept nearer the top of the sea, whilst the red were at a greater depth, leaving to the black or brown hydrophytes the care of forming gardens and parterres in the remote beds of the ocean.
We had quitted the Nautilus about an hour and a half. It was near noon; I knew by the perpendicularity of the sun’s rays, which were no longer refracted. The magical colours disappeared by degrees, and the shades of emerald and sapphire were effaced. We walked with a regular step, which rang upon the ground with astonishing intensity; the slightest noise was transmitted with a quickness to which the ear is unaccustomed on the earth; indeed, water is a better conductor of sound than air, in the ratio of four to one. At this period the earth sloped downwards; the light took a uniform tint. We were at a depth of a hundred and five yards and twenty inches, undergoing a pressure of six atmospheres.
At this depth I could still see the rays of the sun, though feebly; to their intense brilliancy had succeeded a reddish twilight, the lowest state between day and night; but we could still see well enough; it was not necessary to resort to the Ruhmkorff apparatus as yet. At this moment Captain Nemo stopped; he waited till I joined him, and then pointed to an obscure mass, looming in the shadow, at a short distance.
“It is the forest of the Island of Crespo,” thought I;—and I was not mistaken.

Maybe you're stuck in the past and you just want to be comfortable. Good news! You can invent air conditioning with two things: falling water and a funky tube.
First, you need a source of compressed air. The best way to get compressed air in the past is by using a trompe!
Tumblr media
A trompe can be built a lot of different ways, but the core idea is that air gets mixed with falling water. The water pulls the air bubbles down with it, and ultimately the air collects in a chamber at the bottom. This air at the bottom becomes pressurized, and the further the water fell, the more pressure it's possible to build. You can build a trompe at a natural waterfall, with an aqueduct, or by digging a hole in the ground for the water to fall down into. It's really pretty simple. Your biggest problems are getting it big enough and making sure that the air will actually stay in the collection chamber instead of leaking out.
The air from the trompe is already at the temperature of the water, which might be enough for you, and pressurized air can be used for a lot of things. But you're used to modern comforts, and we can do better.
Now the clever bit: you need to make a vortex tube:
Tumblr media
A vortex tube is a device for separating a stream of pressurized air into two different streams of pressurized air, one of them hot and one of them cold. It's a mechanical device with no moving parts and it uses no electricity.
Here's a guide to making one using modern materials: https://www.instructables.com/The-Hilsch-vortex-tube/ There's basically two parts that are important: getting the air swirling as fast as possible within the tube, and a valve or cone at the end of the tube which blocks the middle but allows some air at the outer circumference of the tube to escape. That's your hot air, and the cold air gets bounced back the other way to come out the other side.
The cone at the end is probably the trickiest part, since the rest of it is mostly just a bit of pipe, but it doesn't need any fancy materials or technology. It's just a matter of getting the shape right. Once complete, you can outfit your home with hot and cold air on demand. Maybe use some of the cold air to refrigerate your penicillin samples.
I can understand how "modern person thrown into the past gets by pretending to be a healer/doctor" is as surprisingly common of a trope as it is. I mean I'm fluent enough at bullshitting to be pretty sure I could pull it off to impersonate a doctor in any time pre-1800s. If I have no idea what something is or how to treat it, I could just get the opinion of the other whatever-passes-as-medical-professionals around, but if their suggestions sound like bullshit I'm not doing it. And I'll beat the shit out of anyone suggesting bloodletting or mercury. With my healing stick. I've tied little bells on it, that jingle comically with every smack.
The awesome curative powers of my healing stick come from two separate sources: Placebo, and me using it to beat anyone trying to give my patients mercury.

Pneumatic Valves: Understanding Its Importance and Types
One of the most crucial pieces in an automation and control systems are pneumatic valves. These valves are integral part of systems that rely on compressed air for directing the flow of fluid or gasses. Displacement air motors can perform efficiently with correct adjustment and regulators as they control the pressure, flow, and direction of airflow in pneumatic systems which are important applications for many industry sectors. But what is pneumatic valves? Here we are going to discuss more it, and will know about the types of pneumatic valves in market.
What Are Pneumatic Valves?
A pneumatic valve is a device that can control the flow of compressed air in a certain part of the system. It can be either manually operated or electrically controlled using a solenoid, or mechanically actuated. They enable exact movements in machinery and equipment with the precise control of air flow, which is why they are required for businesses that use manufacturing equipment such as automation or transportation.
Types of Pneumatic Valves
There are a number of types in pneumatic valves and they all exists for one or more specific purposes. There are a few types of the pneumatic valves,
Direction control valve: These valves direct the flow of air only in one direction. Some of them are two-way valves other three way valve connected in different configuration according to system requirement.
Pressure Control Valves: These valves are used to regulate the pressure of a pneumatic system and can be designed either as relief or reducing types, allowing them to relieve excess pressure in an over-pressure condition that could damage sensitive parts.
Flow Control Valves: Flow control valves adjust the flow of actuators by controlling airflow. They are used to modulate the velocity of motion in pneumatic cylinders by controlling flow rate.
Check Valves: Flow is permitted in one direction and prevented from the other, but check valves prevent backflow to ensure air or fluid flows as designed and keep everyone happy throughout without ever causing a problem in the system.
Micro Pneumatic Valves: These are specialized in the sense that a task is required where space may be limited or specifically if precision acts out important role. Typical applications for micro pneumatic valves include robotics and small-scale automation systems.
Different Types of Pneumatic Valves Explained
Selection of the right type of valve for application depends on the understanding of different kinds of pneumatic valves. Here’s a brief explanation of a few specific types:
Two-Way Valves: These are simple onoff valves with two ports one for input and one for output.
Three-Way Valves: Three way valves are often used in double acting cylinders to control flow of air to two different outputs to create complex movements.
Four-Way Valves: These valves are used usually to solve the double-acting cylinder issues. But they can direct air to the either side of the cylinder so that air can move either way.
Conclusion
Pneumatic valves are critical components and the basis for pneumatic systems efficiency and effectiveness. And if you know what pneumatic valves are and what kinds there are, you can decide better which valves to use in your systems. From the micro pneumatic valves used for the compact applications to the larger directional control valves for more extensive systems you will be able to determine how to extend your operational capabilities and complete your automation objectives based on the pneumatic valves types. Selecting the proper valve and in turn knowing what the functions are will help you optimize your pneumatic systems for better performance and reliability. If you’re ready to update your pneumatic system with the appropriate valves, Vs Enterprise can assist! Contact us for help and our high quality pneumatic valve solutions!

Brewing Perfection: How to Make the Most of Your Premium Medium Roast Coffee Pack
Tumblr media
Introduction to Premium Medium Roast Coffee
There's something undeniably special about a perfectly brewed cup of coffee. When you open your premium medium roast coffee pack, you're greeted with an aroma that promises warmth and comfort. It’s not just a beverage; it’s an experience. Medium roast coffees strike the perfect balance between rich flavor and smoothness, making them ideal for any time of day. Whether you’re looking to kickstart your morning or unwind after a long day, mastering the art of brewing can elevate your daily ritual into something extraordinary. With various methods at your disposal, there’s every opportunity to unlock the full potential of those beans in your premium pack. Let’s dive into how you can brew perfection right at home!
Brewing Methods for Maximum Flavor
To unlock the full potential of your premium medium roast coffee pack, brewing method matters. Each technique brings out distinct flavors and aromas. Start with the classic drip brew. It’s simple yet effective. Use a good quality filter to allow oils and fine particles through while capturing any unwanted grit. French press fans will enjoy a fuller body in their cup. The immersion process extracts rich flavors, resulting in a bold taste profile that lingers on the palate. For espresso lovers, investing in an espresso machine is key. This method highlights intricate notes and sweetness, giving you a robust shot or creamy latte experience. Pour-over aficionados appreciate control over every step. Adjusting water temperature and pour rate can significantly alter flavor nuances for those who seek perfection in each sip. Experimentation is part of the journey; find what best complements your chosen beans for an unforgettable coffee experience.
Storage and Preservation: Keeping Your Pack Fresh
To truly enjoy your premium medium roast coffee pack, proper storage and preservation are key. Coffee is a delicate product sensitive to light, air, moisture, and heat. Protecting it from these elements ensures you savor every drop of its rich flavor. First off, consider the packaging. If your coffee comes in a resealable bag with one-way valves, that’s ideal. These bags allow gases to escape without letting air in. If not, transfer the beans into an airtight container made of glass or ceramic. Next is temperature control. Store your coffee in a cool place away from direct sunlight—think your pantry rather than on the countertop or near appliances that generate heat. Extreme temperatures can compromise flavor profiles over time. Moisture is another enemy of fresh coffee beans. Keep them away from areas with high humidity like kitchens near the sink or stove. Avoid storing coffee in the refrigerator or freezer unless you plan to use it all quickly afterward; condensation can ruin those precious beans when taken out. And don’t forget about how long you keep it around! While roasted beans maintain their best flavors for about two weeks post-roasting, ground coffee begins losing freshness within hours after grinding. With mindful storage practices, you'll ensure that each cup delivers maximum enjoyment and retains its delightful aroma—a true testament to what premium medium roast has to offer! Take care of your brew today for an extraordinary experience tomorrow.

How to Change a Flat Tire
Few things are as inconvenient as getting a flat tire. Itcan make you late for an appointment, and when you doarrive, you are either frazzled or filthy from theexperience. If you don't know how to change a tire, theexperience is made much worse by having to wait forsomeone to come to your assistance.
Most women couldn't care less about the workings of amotor vehicle and how to change a tire. Unfortunately mostmodern men are as helpless in this respect as most women.I refer to men who can't change their own flat tire as,pardon the expression, "girly-boys".
In this article I will provide simple instructions toprepare you for the inevitable inconvenience of getting aflat tire. Anyone can easily change a tire, even a womanor a girly-boy. But first lets talk about how to avoidgetting a flat tire in the first place.
One way to get a flat tire is when a nail or other sharpobject penetrates your tire. In the old days this wouldcause your tire to go flat within seconds. Today's modernsteel belted radial tires usually just develop a slow leakwhen penetrated. Even if not penetrated by a sharp object,a tire will gradually lose its air pressure. The way toavoid the inconvenience of getting a flat tire is to checkall your tires air pressure regularly.
Today's modern steel-belted radial tires bulge out at theside a little even when they have proper pressure, so youcan't tell by just looking at them if they have properpressure. You need to use a tire pressure gauge. Gaugescome in two main types. One type has a rod that comesjetting out at the end. The other type has a dial. Ineither case you use the gauge by removing the littleplastic cap from the tire's air valve and quickly pushingthe valve end of the gauge onto the tire valve.
You will get a little "hiss" when you do this. If you didit correctly, the gauge will give an accurate indicationof the tires air pressure. Sometimes it takes a littlepractice to get an accurate reading. Compare the readingyou get with the maximum psi (pounds per square inch)written on the sidewall of the tire. Car tires usuallyhave a maximum of 32 psi. Full size light truck tires canhave a maximum of 80 psi.
If the air pressure is too low, there is a risk of thetire breaking lose from the wheel. This would causedangerous rapid deflation of the tire. When a car tire'spressure gets below about 24 psi you risk rapid deflation.If the pressure is too high, there is a risk of the treadseparating from the steal belt. This can also cause rapiddeflation, but usually it just gives you a very bumpyride.
The way to avoid getting a flat tire is to check the airpressure in all your tires regularly. By "regularly" Imean at least once each month. By "all your tires" I meanincluding the spare. It is very common for a person toremove a flat from their vehicle just to learn that theirspare is also flat.
If you find one of your tires has low pressure, you needto pump it up to the proper value. Air pumps come in twomain types. One type has a cord with a plug that goes intoyour cars cigarette lighter. The other type has a cordthat plugs into an AC outlet.
The cigarette lighter type has the advantage that you cancarry it in your car and possibly re-inflate a flat tireat the side of the road, saving the messy job of changingthe tire for later. The disadvantage is that they workvery slowly and can draw down a cars battery. The AC powercord type has the advantage that it can fill tires morequickly, but it‘s rare to find an AC outlet at the side ofthe road.
Possibly the most important thing to know about tires, iswhat to do if you get a flat while speeding down theexpressway. The most important thing NOT to do is slamon the breaks! This is a common cause of roll-overs. Justlet your foot off the gas and look for a level area at theside of the road to pull off.
People that don't know how to change a tire frequentlykeep driving on the flat tire, in search of a servicestation, until the tire is totally shredded. Then insteadof paying ten dollars to fix a flat, they have to pay ahundred dollars for a new tire. Fortunately after you usethe information in this article, you won't get caught inthat situation.
To fix a flat tire you have to jack up the car and replacethe flat tire with your spare tire. Unfortunately manypeople don't even know where the jack is, and some don'teven know how to get the spare out. Don't wait untilyou're stranded by the side of the road to start lookingfor your jack and figuring how to get the spare out.
In the old days, the spare tire and jack where always inthe trunk of the car. Now with mini-vans and SUVs, vehiclemanufacturers have become very creative with hiding thespare tire and jack. Below is a list of places where youmight find the jack.
- in the trunk - under or behind the seat - hidden behind a panel - under the hood Below is a list of places where you might find the spare tire. - in the trunk - under the vehicle - hanging on the back of the vehicle - hidden behind a panel
Go out to your car right now and locate your jack andspare tire. You may need to locate your owners manualfirst to learn how to locate and use your specific jackto change a flat tire. It's better to figure it out nowrather than waiting until you're stranded by the side ofthe road.
If you have never jacked up your car, now is the time topractice. As mentioned earlier, the vehicle should be onlevel ground. The jack usually needs to be positioned ata "peg" or "slot" under the chassis near the tire to beremoved. At first don't jack the car up so high that thetire leaves the ground. Just jack it up to take most ofthe weight of the car off the tire.
Then use the lug wrench to "break" the lug nuts lose. Tobreak them lose you have to turn them counter-clockwise.Breaking the lug nuts lose might take a little muscle. Ifyou left the bottom of the tire on the ground, this willhelp by preventing the tire from spinning or the vehiclefrom rocking. "Breaking" the nut lose means loosening itenough so you can get it off easy, kind of like a jarwith a stuck lid. Just break them lose at this point,don't remove them.
If you're not strong enough to get the lug nuts loose,now is the time to find that out. It is also not uncommonfor a tire mechanic to over-torque lug nuts, or striptreads so the lug nut can't be removed. To get the lugnuts off you may have to use "leverage". That is, make thehandle of the wrench longer, for example by putting a pipeover it. In any case now is the time to learn aboutproblems with getting the lug nuts off - not when yourstranded at the side of the road.
After you have broken the lug nuts lose, jack the vehicleup higher. Jack it up just high enough so that the tireleaves the ground. Then remove the lug nuts and the tire.
There are two types of spare tires. You are lucky if youhave a full-sized spare. Most cars today have a "space-saver" spare. A space-saver is thinner than a regulartire. The space-saver works like a regular tire, but thereare two things to be aware of. First, space-savers arerated for only 50 mph. They are intended just to get youto the service station. Second, the air pressurerequirement for a space-saver is usually much higher thanthe regular tires for your car. Make sure you keep itfilled to the proper pressure.
Next put the spare tire over the lug studs and put the lugnuts back on. Start the lug nuts with your fingers to makesure you don‘t cross treads. After you have the lug nutsstarted, use the wrench to turn them on all the way. Afterthe lug nuts are all the way on, jack the vehicle backdown until the tire touches the ground. Now you can torquethe nuts down tight.
There is always the question; how tight do I make the lugnuts? There is actually a specification (which tireservice personnel usually ignore). For example; 95 ft. lbs. as indicated on a torque wrench. But for the averageperson without a torque wrench, it's a matter of feel.
You want to tighten the lug nuts tight enough so that youare confident they won't come lose while you are driving,yet not so tight that you can never get them off again.Don't be a super man and tighten them until you strip thethreads or break the stud. Just make them tight enough sothat you are confident they won't come lose while you aredriving. It's a matter of feel. After you have tightenedthe lug nuts, remove the jack.
Fix or replace the flat tire ASAP. Murphy's law number 66states that if you don't have a good spare tire you willimmediately get a flat tire. Fix or replace the flat tireon the next weekend if you can't do it sooner.
If you don't know how to locate the jack, access thespare, and replace a tire on your vehicle, I suggest yougo do it right now for practice. If you are prepared andconfident, getting a flat tire will be a minorinconvenience, rather than a bad experience that screws upyour entire day.
How Important Is The Car Tire Pressure?
Discover the importance of having the right tire pressure in your car tires.
Tires are a vital part of our vehicle, directly affecting driving safety, as they are the only parts that bring the car into contact with the road surface.
Don't neglect the pressure of the car's wheels.
When tires are not correctly inflated, they get hotter and therefore lose a lot of load capacity.
Also, being hotter causes more friction, and the car consumes more fuel. Overheating the tire causes it to start deforming rapidly, affecting the whole architecture of the tire and creating the risk of a blowout.
Another negative consequence of insufficient tire pressure is reduced driver control of the vehicle, and proper tire condition and correct inflation pressure are strictly related factors.
Not having adequate pressure can lead to tire deformation and premature wear. For this reason, we must control every month's pressure on the tires of the car, including the spare tire.
What is the recommended pressure that my tires should have?
The manufacturer's tire pressure should be recommended in the car's instruction book, as the tire pressure can vary considerably depending on the tire brand and size.
The most commonly used unit of measurement for tire pressure is the psi (pound per square inch). Generally, light cars have a recommended pressure of between 28 and 36 psi.
The tire pressure gauge is the appropriate tool to measure car tire pressure, also called "pressure gauge." You can purchase it or go to your nearest service station at the time. Usually, all service stations have a designated area for water and air. Tires often lose pressure over time. You should check your tire pressure when you think your tires might lose air, sometimes because of a bad valve, a damaged metal wheel, or a puncture (nail in tire). On the other hand, excessive tire pressure reduces the tire's life, decreases ground adherence, and makes it difficult for any car driver to control the vehicle. Are you now convinced of how important it is to checking tire pressure? Here are the steps to follow. How to measure the tire pressure correctly?
Tyre pressure is measured cold. Make sure your tires are cold, so you haven't traveled many miles before measuring the pressure.
Stop the engine, apply the handbrake, and get out of the car.
Remove the cap from each wheel, not forgetting the spare. They are usually dark and are on the inside of the rims. Be sure to save all the caps well, so you don't lose them.
Take the hose from the air machine and hook it to the spout of the tire. Do this gently, but make sure that the hose reaches the end of the spout.
Look at the air machine for the pressure in each tire.
Compare these figures with the tire pressure table recommended by your car manufacturer.
If the figures are below, you must put them in the air. If they are above, you must remove it.
 
As you can see, measuring tire pressure is a straightforward task. Still, it is of vital importance for road safety, the life of the tires, and other parts of the vehicle, as well as another way of avoiding excessive fuel consumption.
We love for you to visit this website if you want to know more about car tires. Tires are one of the topmost crucial parts of the auto. Therefore we should take care of them.

These  dampers also play a crucial role in controlling the rate of combustion, ensuring your cozy fireplace experience doesn’t turn into a smoke-filled nightmare.
But it’s not just about fireplaces and chimneys. Dampers are the crucial part of centralized air conditioning systems too. They can isolate unused rooms to save energy or regulate airflow for room-by-room temperature control. It’s like having your own personal climate butler ensuring every corner of your space is just the way you like it.
Let’s Explore more types of Industrial dampers
Multi-Blade Control Dampers:
Multi-blade control dampers, also known as rectangular or multi-blade louver dampers, come in two varieties based on blade action.
-Parallel Blade Action: All blades open and close at the same angle and direction.
-Opposed Blade Action: Adjacent blades rotate in opposite directions.
Single Blade Dampers:
Single blade dampers, known as butterfly or wafer dampers, are versatile and can be round, square, or rectangular.
-They may feature single thickness blades or a double skin airfoil design.
-Often, they provide a cost-efficient alternative to pricier valves.
Commercial and Industrial Backdraft Dampers:
Also called gravity dampers, backdraft dampers are vital in light, medium, and heavy-duty industrial and HVAC applications.
-These Industrial dampers allow airflow in one direction while preventing reverse flow, crucial for maintaining system integrity.
-Commonly installed on fans to prevent backspin caused by back pressure.
Face and Bypass Dampers:

Ricoh offers ValveJet heads
Tumblr media
Ricoh has highlighted its ValveJet printheads at the Fespa show in Amsterdam, with the announcement that these are now being offered to OEM customers for a variety of industrial applications.
Graham Kennedy, Ricoh Europe’s director of industrial print solutions, explains the advantage of using ValveJet over piezo heads, “It’s about larger drops for fast area coverage. You have larger throw distances where you are not limited to having to decorate on a flat surface. And then high viscosity ink so you could move to automotive painting where the inks are more than 100 cp.”
The principles behind the Valvejet approach are fairly simple. There is a hole at one end of the fluid chamber, which is closed by a valve and Ricoh is using a piezo actuator to open and close this valve. The fluid is supplied from a pressurized tank so that when the nozzle is opened, the air pressure is enough to force the dropout. It’s not suitable for highly detailed work – typically having around 70 – 140 dpi, though Ricoh says this could be improved on.
Yoshihiro Moriya, head of inkjet engineering at Ricoh UK’s Inkjet Technical Centre, explains that by controlling the length of time the nozzle is opened, it’s possible to determine the size of the drop. It’s also possible to multi-pulse the drops, for example, firing three small drops that could combine in flight to create a larger drop before reaching the substrate.
The ValveJet heads are available as either single nozzle NT units or as the Gelart printhead, which has eight nozzles combined. The advantage of the single nozzle units is that integrators are free to decide how many channels they need and how they want them arranged. They can then be configured on a block – effectively a printhead – with the electronics, as can be seen in the picture, where the black module in the center of the image is the printhead unit with the silver NT nozzles. Jason Remnant, strategic business development for Ricoh Europe, points out, “It’s easier for OEMs to integrate it as a printhead. A customer can create their own block and add their own value or they can buy a pre-made head with eight channels.”
To illustrate this, Ricoh has shown off a tire-printing application, which combines six single nozzle units together, one each for jetting CMYK, plus white and a primer. Kennedy explains: “We put the primer down first and then heat up the tire to about 120°C and this excites the surface and the ink is cured directly on the surface as the tire cools.”
Kennedy says that there is a lot of interest in this solution for sports such as Formula 1 as well as touring car racing, where the vehicles are wrapped with advertising and branding so the tires are an extension of this. The same can also be used for customizing vehicles for private use. Kennedy points out that tire printing offers another way of adding value and differentiation. The inks are water-based but can last for up to a year, which is likely to be the lifespan of the tires themselves.
I wrote about Ricoh’s ValveJet heads when they were first introduced two years ago. Since then Ricoh has been developing print systems with these heads for the last two years and has a number of solutions. This includes one for printing directly to gas cylinders, another for the sides of trucks as well as for shutters for retail units. Ricoh is open to working with OEMs for variations on these devices but is also hoping to talk to integrators that want to use the ValveJet approach to create their own solutions.
Kennedy says, “This is the first time we have shown this for OEMs, just to gauge where the interest lies. We will develop the story ready for Drupa and will have more of an opportunity to engage with a wider range of OEMs at a much bigger event.”
