We were explicitly told you should NOT go in the hole. Why did they send you down there???

im allowed to go in the hole. im built different

but heres the whole story. theres no short way to describe it so bear with me:

a few weeks ago a radiation shield got stuck in the bottom of our machine, ~10 feet down a 1.5in diameter tube. the radiation shield prevented us from actually accessing our spectroscopy stage, if we couldn't get it out…the whole 1.5 million dollar machine is completely unusable.

To get it out, we had to break open the chamber. but this involves opening spaces that were previously maintained at a vacuum of well over one million times below atmospheric pressure which is.....intense. (as an aside, cracking open the chamber involved flooding the chamber with pure nitrogen gas to maintain positive pressure, which also flooded the room with nitrogen too....which is a major suffocation risk so we had to work in 10 minute shifts. this also gave us a hard countdown for how long we could attempt to fish the shield out before we ran out of gas. and folks, fishing for a tiny shield at the bottom of such a small shaft was wicked difficult) but we got it! here's shots of the actual extraction:

Once we actually got the bastard out, we have to pump everything back down to ultra high vacuum to protect our surfaces from contaminants before we can do any experiments again. To do that we have to cook the whole maschine like a casserole......and thats why i was in the pit! I had to prepare the hole to support our cryogenic dewar and wrap the exposed chamber in foil

Cryosleep: Unraveling the Mysteries of Ageing Is Anti-Aging Technology a Reality or a Fantasy

Cryosleep, also known as cryogenic suspension, is a process where a person is cooled to very low temperatures until it is possible to resuscitate them in the future. The core body temperature is lowered to just above the freezing point of water to put metabolic activities including brain function on near-halt until tissues can be repaired. Though sometimes portrayed as a means to survive death in popular science fiction, Cryosleep remains an experimental medical procedure with many technological and biological hurdles yet to be overcome.

The Freezing Process

When a person is cooled for Cryosleep, the first step is to drain their blood and replace it with an organ preservation solution. This prevents damaging ice crystals from forming during the freezing process. The body is then cooled at a very slow and carefully controlled rate of around 1°C per minute to avoid lethal tissue damage. Modern cryonics facilities can lower temperatures down to -196°C using liquid nitrogen for long-term storage. At such low temperatures, all biological activity and decay essentially ceases. However, successfully bringing the person back to normal health remains extremely difficult with current science.

Challenges of Cryopreservation

One of the biggest challenges to Cryosleep is preservation of the brain. Ice crystals that form during freezing can pierce cell membranes and rupture tissue. Slow freezing helps minimize this effect but does not eliminate it completely. Rewarming thawed tissue also poses risks, as damage may not become apparent until cells try to function again. There is also no certainty that technologies will exist in the future to repair all the microscopic injuries from cryopreservation. The longer a person remains frozen, the greater the cellular degradation from both the initial freezing and long-term storage at very cold temperatures.

Another issue is whether a cryopreserved brain could even be brought back to a functioning, conscious state. Freezing may irreversibly alter connectivity between neurons and synapses. Under optimal conditions, cryobiologists estimate less than 10% of a frozen brain's connections could withstand preservation and rewarming. It is unknown if this level of cellular disruption would permit restoration of a person's mental faculties and identity. Cryonics advocates counter that as nanotechnology and regenerative medicine advances, repair may become feasible. However, most researchers remain highly skeptical.

The Prospect of Future Resuscitation

Even if all physical damage from freezing could eventually be repaired, reviving someone after years in Cryosleep still poses enormous ethical challenges. Would they truly be the same person given the vast changes in technology, society, and relationships that will have occurred? There are also no guarantees that future medicine could cure whatever condition originally led to their cryopreservation. They would essentially be transferring from one illness to another.

Legally, Cryosleep clients often sign contracts agreeing to assume all risks and costs of future resuscitation attempts. However, it is impossible to foresee how societal views may evolve or what financial burdens might exist centuries from now. There are no laws governing if or how long the "custodial" duties of a cryonics firm could be enforced over potentially indefinite time periods. The possibility of reviving someone could be viewed quite differently in a distant future that has progressed far beyond today's level of medicine and technology.

Current Cryosleep Efforts

Though still quite experimental, some organizations are actively pursuing research and limited trials of Cryosleep procedures on animals and cadavers. Alcor and the Cryonics Institute in the United States currently store around 200 human patients cooled to cryogenic temperatures in insulated metal dewars of liquid nitrogen. The patients' heads are often separated from their bodies to optimize the freezing process. Russian biostasis company KrioRus also offers cryopreservation but has fewer long-term clients stored.

Results from experiments on smaller animals provide some grounds for cautious optimism. Frogs and even rats have survived weeks of cryopreservation and showed limited signs of recovery after thawing. Primates have withstood five hours of deep hypothermia with their brains mostly intact. However, successful resuscitation from full Cryosleep at depths required for long-term storage remains unproven even in simple organisms like worms. Considerable technological strides will clearly be needed before researchers can seriously contemplate reviving cryopreserved humans.

Is Cryosleep Really Possible?

While the possibility of long-term biostasis through Cryosleep is alluring as a potential solution to aging and mortality, most biomedical engineers and biogerontologists remain highly skeptical it can ever truly revive a normal, conscious human being. The technical obstacles around freezing, long-term storage at extreme cold, and restoration of healthy cellular and brain function may prove insurmountable given what is presently known about cryobiology and the limits of medicine. Cryonics advocates counter they only need basic repair capabilities become available centuries from now. However, others argue if such advanced healing was achievable, aging itself could probably be cured or reversed through other methods.

Cryosleep must be considered an experimental extremity, not a proven way to survive into an indefinite future. Whether freezing humans might ever transition from science fiction to reality depends heavily on breakthroughs yet to emerge fromcryobiology and regenerative medical research. While a few are willing to bet on that chance through cryonics arrangements today, the ultimate fate of cryopreserved patients is unknowable. Cryosleep’s transformation from speculation to reality remains limited more by what science can deliver than what imagination can envision. Only continued scientific progress will determine if it is truly possible to suspend life indefinitely in a state of ice-preserved animation.

OVERVIEW OF MEDICAL GAS MANIFOLDS

WHAT IS A MEDICAL GAS MANIFOLD?

Unlike Medical Air Compressors and Vacuum Pumps that generate gas on-site, many gases used in healthcare settings are delivered to the facility in different types of containers and use manifolds to distribute into the rooms. Gases that can be delivered:

Oxygen – delivery pressure of 50psi

Nitrous Oxide – delivery pressure of 50psi

Medical Air – delivery pressure of 50psi

Carbon Dioxide – delivery pressure of 50-100psi

HeliOX blends – delivery pressure of 50psi

Nitrogen – delivery pressure of 180psi

Instrument Air – delivery pressure of 180psi

The 2021 edition of the NFPA99 has the most recent developments in medical equipment and processes as well as new methods to reduce fire, explosion, and electrical hazards.

WHAT CONTAINERS ARE USED WITH MANIFOLDS?

Bulk tanks and micro-bulk tanks are gas containers that get refilled on-site. These are used for large applications and require additional equipment. Sometimes, these are collectively called a tank farm and the pad – which allows access for a truck with cryogenic gas to pull in and fill the tanks. Liquid Dewars and high-pressure cylinders are the types of gas containers that are delivered and replaced when empty. For example, there is an “H-type” high pressure cylinder, which is primarily hooked up to a high-pressure manifold in the healthcare setting. These are very common for ambulatory surgery centers and small outpatient facilities, most of the gases listed above outside of oxygen, still use this type.

HIGH PRESSURE AND LIQUID MEDICAL GAS MANIFOLD INSTALLATION

Discussing high pressure and liquid medical gas manifolds located indoors, the number one aspect is that it has to be a separate secured room with one hour fire rating used for no other purpose. Your manifold room can only have the manifolds and the container that is being replaced. You can store and keep connected what you’re actually using.

For example, if you have Dewars, you are only able to store Dewars, and then your high-pressure cylinders (H tanks) can go in there. Sometimes people put the vacuum pump and the oxygen manifold in the same room – that is not allowed and very expensive change order. Remember, your manifolds must be in a room all by themselves and be properly labeled.

Although this blog discusses the most common practices, Pattons Medical advises you to always work with your local municipality and local verifier to ensure that your design complies with your interpretation of whichever code they’re working on. Additionally, please note that any electrical devices in this room must be situated above five feet, and relief valves must be installed with copper piping that extends outside the room. The discharge should be turned down and screened for safety. Another important consideration is having a source valve located near the manifold.

When it comes to the insulation of the room, there are several other factors to take into account. Firstly, the temperature inside the room should not exceed 125 degrees. Additionally, ventilation must be carefully planned and implemented to ensure optimal conditions. You are able to naturally ventilate the room if your total gas falls below 3000 cubic feet. You can access gas volume charts on the Pattons Medical website.

Reference NFPA 99 5.1.3.3.2 (1-9) for design and construction details for locations of central supply systems and storage of positive pressure gases.

Indoor rooms can be heated by indirect means using steam or hot water if needed. The common rule of thumb for your liquid containers, your Dewars, is depending on the gas, it could be between 12 and 16 H cylinders. You will know where you are in that 3000 cubic feet threshold by the math and whether you want to do the mechanical versus the natural.

Liquid Dewars

High Pressure Cylinders

HOW DO MEDICAL GAS MANIFOLDS WORK?

With medical gas manifolds, you will have two banks; the primary and the secondary, and they are required to be equal. In regards to space, the primary bank is the one currently supplying the gas, and then the secondary bank will be ready when the primary is depleted. The manifold is required to be fully automatic. Referring to the NFPA applications, the switchover must occur within the manifold, semi-automatic.

Discussing the manifold and the header bars, the header bars will need to be equipped with high-pressure shutoff valves outside the cabinet to allow for emergency isolation. You also will need to have integral check valves for each station. The header bar is going to be CGA gas specific. This means your H cylinder (your Dewar), has a certain threaded connection – similar to the header bar. The goal is to prevent a nitrogen, H cylinder from being hooked up to an oxygen manifold. With the CGA fittings, the manifold is equipped with pressure transduced – which will send information to the main circuit board for a remote signal. This is how it will talk to your master alarms. Since you will need to place this outdoors, the NEMA four gives you some weatherproofing. You will need to make it a NEMA four cabinet if you are going to do it outside. Pattons Medical recommends putting a cover or shelter over it.

WHAT’S INSIDE A HP MANIFOLD?

The manifold is going to come equipped with a three-quarter inch shutoff valve, which makes up a manifold for high pressure. At the bottom of the diagram, is the pressure transducers that are telling you what pressure is happening in each side, your left and right bank, and your primary and secondary. Then, we go into the left and right bank dome regulators. The important part about using the dome biased regulators is that it’s what holds the pressure to allow the whole thing to work off pressure differential.

Above those, are the first line regulators. Then, the bank gauges at the top tell you what's going on in these headers. After that, there’s the pilot regulator, which is feeding pressure into the dome bias, so your dome bias regulator is about 25 – 30 PSI higher than the one that it’s currently feeding.

When a facility gets gas delivered to their site, they are paying for gas at a certain purity, when the gas gets delivered on site, there is no way to make it pure. Manifolds can affect the purity of the gas, so if you’re not using high quality regulators that are made for NFPA applications, then there is potential through the regulator to introduce some impurities into the gas as it flows through the manifold. The left bank is feeding the facility, but when it drops to 250 PSI, it is no longer satisfying the dome biased, then it’ll switch to the secondary bank.

The manual purge valve will test for purity. The pressure relief valve is there to let you know if something is wrong and it will relieve off. When you are determining the flow through the manifold, some spec sheets give you the flow with both your left line regulator and your right line regulator being open, flowing through both, but this is not accurate for an NFPA application. For maintenance, the left line regulator will be manually turned off and then the right line regulator will need to be turned on. That is strictly to keep the wear and tear equal within the manifold.

There are manifolds on the market that use what’s called a “switching,” which is when it switches to where the pressure is after one side no longer has any pressure. The issue with this is that they leak and cause a waste of gas. The other caveat is that they fail frequently in the middle, so they haven’t closed the left bank but they opened the right bank. So, you end up using both banks at once with no warning.

HEATERS

CO2 and nitrous are two gases that can potentially freeze up a manifold. This is caused by a pressure drop and flow across the regulators in the orifice in the manifold. If you’re going to use a manifold with a shuttle valve, you must have a heater for CO2 and nitrous oxide because they leak. Then, you will be left with a slow flow the eventually freezes, so you’ll need to use a heater. We have a high flow dome bias regulator in our manifold, our specification sheets do not specify a heater with a Pattons Medical manifold. It isn’t needed because Pattons Medical picked a regulator that would give us high flow. Pattons Medical also wanted to make it so that heaters weren’t needed because they add to the room which causes another fail point. The heaters basically work by switching on when the room temperature drops below 75 degrees.

LIQUID X LIQUID MANIFOLD

In larger facilities, the number of high-pressure cylinders required to meet the demand can become very high resulting in a huge space requirement and a very labor-intensive change out. In those instances, cryogenic containers become advantageous. If using cryogenic containers, there are options pertaining to the primary and secondary banks. If using a liquid manifold, a HP reserve manifold is required as back-up.

INTELLISWITCH MANIFOLD

The IntelliSwitch manifold is the product we will need to use if you are using a liquid-by-liquid application or high pressure. One of the unique features of the IntelliSwitch manifold is the flexibility.

When you push the button on the front, it allows you to identify what is being connected to this manifold. What this manifold's able to do is when you tell it what is connecting to it, it will understand what pressure is supposed to see based on the containers being attached.

When you liquefy the gas in the container, it introduces some challenges with the gas being in a cryogenic state. IntelliSwitch is able to address some of those challenges. One of the first features is the economizer function. For this example, we will say, that this bank is feeding the facility. When this bank is feeding the facility, this container is generating head pressure because the gas does not want to be in a liquid state. When it generates too much head pressure, that's when you're going to pop your pressure relief valve to protect the container. In a traditional liquid by liquid manifold, it blows off into the room.

The IntelliSwitch is able to monitor the pressure on the bank, feeding the facility. Still, it’s also monitoring the pressure of the bank, not feeding the facility when it starts to register, that the head pressure is getting to. The economizer feature just bleeds some of that gas off so that it's able to be used downstream and you don't waste it. All of this happens in reverse with the lookback feature.

The lookback feature will do a soft switchover, and start drawing some of the gas from this bank, but then it keeps looking back. When this generates enough head pressure, it uses it. If it notices that there is no type of gas or that its completely empty, it’ll switch to the alternative. So instead of wasting 30% of gas in the container, only 5% will be wasted. The majority of verifiers say that this is a safer product because you are constantly getting readouts from both, meaning you know exactly what the pressure is.

ALARMS

For the manifold, there are local and master alarms. The local alarms are physically on the cabinet and are going to have either green or red lights. These lights will be next to a few phrases; ready, in-use, and replace.

For reference, you should have two green lights for ready, which means you now have a demand. For this example, let’s say this is your primary bank. When it’s depleted, the red light will be next to “replace” and the green light will be next to “ready” and “in-use.”

At your master alarm, you have a low-pressure line, high-pressure line, and reserve in use. They are actually being read by the main line pressure switch downstream of the source valve, but then you have your changeover alarm. Similarly to the local alarm, if the red light for “replace,” it is telling you to change over. You will need to address getting the bank changed out within a specified timeframe.

For liquid by liquid, we have those same three alarm points at the master, but we also have to have two more points at the master alarm, called reserve in use. As mentioned, for liquid-by-liquid applications, you have your two cryogenics and your high pressure. If your cryogenic containers have both failed, we will take off our “reserve-in-use” for the high-pressure reserves. The reserve manifold will trigger an alarm at the master.

Cryogenic dewar flasks are typically constructed with a double-walled design, with a vacuum-sealedspace between the inner and outer walls. This vacuum acts as a thermal barrier, preventing heat fromentering the flask and maintaining the low temperature inside. The inner wall is usually made of stainlesssteel or other materials with high thermal conductivity, while the outer wall provides structural supportand additional insulation. The space between the fences is often evacuated to further reduce heattransfer through conduction and convection. Additionally, some dewar flasks incorporate reflectivecoatings on the inner surface to minimize radiant heat transfer. The YDS liquid nitrogen cylinder is used in various industries such as biotechnology, healthcare, and research. It contains liquid nitrogen, which is a commonly used cryogenic fluid. Its main purpose is to store and transport biological samples, cells, tissues, and other materials at ultra-low temperatures to ensure their long-term preservation and quality during storage and transportation.

Liquid nitrogen dewar and cryogenic nitrogen dewars

Liquid nitrogen dewar also known as a cryogenic dewar or LN2 dewar, is a specialized container designed for the storage and transportation of liquid nitrogen (LN2) at extremely low temperatures. Liquid nitrogen is a cryogenic liquid with a boiling point of around -196 degrees Celsius (-321 degrees Fahrenheit) at atmospheric pressure. Due to its extremely cold temperature, it requires specialized storage solutions to prevent rapid evaporation and maintain its cryogenic properties.

Here are some key points about liquid nitrogen dewars:

Design and Construction: Liquid nitrogen dewars are typically constructed from materials with low thermal conductivity, such as stainless steel or glass-reinforced plastic, to minimize heat transfer from the environment. They consist of an inner vessel to hold the liquid nitrogen, an insulating vacuum layer to reduce heat transfer, and an outer protective casing.

Double-Walled Insulation: The most common design for liquid nitrogen dewars involves a double-walled vacuum insulation. This vacuum layer between the inner and outer walls significantly reduces heat transfer through conduction and convection, helping to keep the liquid nitrogen cold and reducing the rate of evaporation.

Capacity: Liquid nitrogen dewars come in various sizes, ranging from small containers with capacities of a few liters to large tanks that can hold thousands of liters. The choice of dewar size depends on the intended use, storage duration, and amount of liquid nitrogen needed.

Pressure Relief: As liquid nitrogen evaporates, it produces nitrogen gas, which can lead to an increase in pressure inside the dewar. To prevent excessive pressure buildup, liquid nitrogen dewars are equipped with pressure relief valves to maintain safe operating conditions.

Handling and Safety: Proper handling of liquid nitrogen and its dewars is crucial due to the extremely low temperatures involved. Protective gear, such as gloves and goggles, should be worn when handling liquid nitrogen, as contact with skin can cause severe frostbite. Additionally, adequate ventilation is important to prevent nitrogen gas buildup in enclosed spaces.

Applications: Liquid nitrogen dewars are widely used in various fields, including scientific research, medical applications, and industrial processes. They are used for freezing and preserving biological samples, cooling sensitive equipment, and conducting experiments in low-temperature environments.

Filling and Refilling: Liquid nitrogen dewars need to be periodically refilled as the stored liquid nitrogen evaporates over time. This can be done by transferring liquid nitrogen from a larger storage tank using proper safety procedures.

Transportation: Some liquid nitrogen dewars are designed for safe transportation of the cryogenic liquid. These transport dewars are equipped with features to minimize liquid nitrogen evaporation during transit.

Cryopreservation: In medical and biological applications, liquid nitrogen dewars are used for cryopreserving cells, tissues, and even human reproductive material like sperm and eggs. The extremely low temperatures of liquid nitrogen help preserve biological samples for extended periods.

It's important to note that working with liquid nitrogen and its dewars requires proper training and adherence to safety guidelines due to the potential hazards associated with cryogenic temperatures and pressure. Always follow recommended safety practices to ensure the safe handling and use of liquid nitrogen and its containers.

Cryogenic nitrogen dewars commonly referred to as LN2 dewars, are specialized containers designed for the storage, transportation, and handling of cryogenic nitrogen, specifically liquid nitrogen (LN2).

The dewars are constructed using materials with low thermal conductivity to minimize heat transfer and maintain the cryogenic state of nitrogen.

Construction and Insulation: Similar to other dewars, cryogenic nitrogen dewars have double-walled insulation with a vacuum layer in between. This design significantly reduces heat transfer, thereby prolonging the retention of cryogenic temperatures and minimizing LN2 evaporation.

Pressure Control: Cryogenic nitrogen dewars are equipped with pressure relief systems to manage the buildup of nitrogen gas as the liquid nitrogen evaporates. This ensures that the internal pressure remains within safe limits.

Variety of Sizes: Cryogenic nitrogen dewars come in various sizes, catering to different storage needs. They can range from small portable units used in laboratories to larger tanks used in industrial and research settings.

"Weirdest thing I've ever sold my soul for but okay—"

John starts off feeling like his time is being wasted but before long his bastard-mindedness takes over

"Steady, steady—" John mumured as Danny slowly poured some kind of phosphorescent liquid nitrogen shit into the cryogenic storage dewar. The fog spilling out emanated the whispers of the grave.

Through the dewar's clear window, John concentrated on his work. An actually functional runic circle gleamed ominously on the bottom of the container; it's light matched the glow of John's palms, hovering on either side of the container.

"I'm being frickin steady," grumbled the teenage High King of the Infinite Realms (who also somehow did not know any runic magic.) "Almost done... Okay."

John held his breath as the last of the ripples settled and the container was sealed. Releasing a slow breath, he waited a minute just to be safe, then slowly released his magic protecting the chalk drawn on the inside of the container.

The runes continued to glow. They didn't shift from the still fluid resting on top of them.

"Ah ha! It worked!" Danny crowed, weightlessly flipping into a mid-air somersault.

John smirked. He backed away carefully. "They're going to be ripping their hair out." He offered a hand to shake. He still reeled from doing something so harmless and silly with such a powerful being. "Pleasure doing business."

"Yeah! Here—let's exchange numbers..."

They left the dewar behind in Danny's workshop; the only one that hadn't been found yet. In the dark, halfway underneath a work table, a measly spell to produce light glowed ethereally.

Whoever found it would think they had finally found the secret. Then, at the slightest bump, the fluid would jostle the chalk powder, erasing the runes irreparably.

Now, all John had to do was wait. That would be a really fucking funny phone call.

Danny gets his first adult job as an ice sculptor. As a freelance artist he can set his own hours and make his own contracts. He earns a reputation for being able to deliver large, complex sculptures on a tight schedule. Rumor has it that he uses a special chemical formula for his ice to make it last longer. His early work started a bit rough around the edges but as the years pass his craftsmanship and creativity vastly improve.
