摘要： A receptacle for maintaining perishables, such as food, at a reduced temperature features an exterior shell joined to an interior shell so that a space occupied by a vacuum exists between them. The junction of the inner and outer shells is located on the exterior of the receptacle. Phase change material is disposed within compartments in the bottom of the receptacle and is covered by a false bottom. A cryogenic liquid, such as liquid nitrogen, is poured down the interior walls of the receptacle and into the compartments containing the phase change material so that the phase change material is frozen in situs. A liquid absorbing material may be substituted for the phase change material.

摘要： An insulated container that is open on top and contains phase change material travels along a conveyor. The container initially stops under an infrared sensor whereat its initial interior temperature is determined. A microprocessor uses the temperature data to determine the amount of cryogenic liquid that must be added to the container so that its phase change material will be frozen to a predetermined temperature. A cryogenic liquid dispenser charges the container with an amount of cryogenic liquid determined by the microprocessor. The cryogenic liquid dispenser includes a phase separator which depressurizes cryogenic fluid received from a bulk storage tank. Once the container is charged, it may be loaded with perishables, examples of which include food, blood or chemicals.

摘要： An insulation system is described which includes a containment wall with an inner surface and an outer surface, the inner surface at least in part defining a volume for containment of fluids or solids, an absorbent material which releases absorbed material when heated, the absorbent being in thermal contact with the outer surface of the containment wall, a structural wall contiguous to the outer surface of the containment wall, and an interior surface of the structural wall and the outer surface of the containment wall defining a volume of space where a vacuum can be maintained. The insulation system is used in a process for improving the performance of the insulation system, the process comprising the steps of:a) heating the containment wall to a temperature which will heat the absorbent material to a temperature which will cause the absorbent material to release absorbed material,b) removing the released absorbed material from the vacuum zone, andc) closing the vacuum zone, while under a reduced pressure to exclude ambient passage of gas into the vacuum zone. The process is highly effective even where the reduced pressure of step c) is substantially less than 0.25 Torr.

摘要： A delivery and storage system for cryogenic fluids features a vehicle mounted dispensing system including a bulk storage tank that feeds cryogenic liquid to a sump containing a pump to pre-cool the pump. The pump feeds cryogenic liquid to another sump containing a meter so as to cool the meter. A valve selectively routes the cryogenic liquid from the meter sump to the bulk storage tank as the meter cools down. When the meter reaches operating temperature, cryogenic liquid is directed through the meter to a dispensing hose. The cryogenic liquid is dispensed into a liquid cylinder. The liquid cylinder features an automatic shut-off device to reduce the flow of the cryogenic liquid into the cylinder when the cylinder is full. The inner shell is held to the outer shell at the top by a combination stainless steel hose and composite cylinder neck. The bottom of the inner shell features a pair of pins which are supported by a strap across the bottom portion of the outer shell interior.
