摘要： An enclosed cryogenic storage tank having an insulated bottom, a vertical insulated wall projecting upwardly from the bottom, an insulated roof projecting to the wall and completely covering the space surrounded by the wall, and an insulated deck inside and extending across the tank at a fixed location between the tank bottom and tank roof. A process of removing a subcooled liquefied gas from the space beneath an insulated deck in an insulated cryogenic storage tank, feeding the removed subcooled liquefied gas in heat exchange with a stream of warm liquefied gas of the same composition as the subcooled liquefied gas to cool the warm stream, returning the subcooled liquefied gas to the tank below the deck, and feeding the cooled stream of liquefied gas to the tank above the deck. Alternatively, a stream of the subcooled liquefied gas can be mixed with the steam of warm liquefied gas and the combined stream then fed to the tank above the insulated deck.

摘要： Life support is provided by a cryogenic closed circuit system for either hyperbaric, isobaric or hypobaric respiratory environments. Oxygen content in a gas mixture is maintained in a selected partial pressure range by establishing thermodynamic equilibrium between a liquid oxygen supply, which is maintained at an appropriate temperature, and a gas mixture within an enclosed volume communicating with the liquid oxygen. Incoming gases are passed into the gas-containing volume and adjusted to an appropriate partial pressure of oxygen solely by virtue of saturation equilibrium, and independently of ambient pressure and gas mixture variations. The useful life of a given oxygen supply volume is greatly extended because of the high compaction ratio of liquid oxygen with respect to oxygen gas at standard temperature and pressure, and because of full physiological use of the oxygen. The temperature of the liquid oxygen may be controlled through the use of a cryogenic reservoir, a cryogenic refrigerator or other means. A heat exchanger may be deployed in the closed circuit system to cool incoming contaminated gases to cryogenic levels and to heat outgoing breathable gases to acceptable levels, and to provide more efficient use of the cryogen. The closed circuit system may further include means for compensating for ambient pressure variations by the injection of an inert gas or gases and for cleansing of incoming gases by removal of water vapor and carbon dioxide.

摘要： Disclosed is a device for transferring a cryogenic fluid from its storage vessel to cryostat or other vessel. The device is an open ended tube of sufficient length to permit its lower extremity to project below the surface of the fluid when it is inserted into an opening in the vessel. The tube is fitted with a collar which forms a substantially airtight seal between the tube and the opening. A heater capable of producing sufficient heat to vaporize part of the fluid is attached to the tube. The vaporization creates an internal pressure which forces the fluid up through the tube. By insulating the heater from the tube so that the fluid forced into the tube is not vaporized, a steady flow of cryogenic fluid is delivered to a desired location, e.g., a cryostat.

摘要： 959,493. Pumping systems for liquefied gases. CONCH INTERNATIONAL METHANE Ltd. Dec. 1, 1961 [Jan. 16, 1961], No. 43101/61. Headings F1C, F1G, F1R and F1T. [Also in Division B8] A pumping system for liquids such as liquefied natural gases comprises a turbine 16 driving a pump 10 near the bottom of the liquid container and the working fluid has a solidification temperature below the temperature of the liquid 18 in the container 14. The turbine 16 may be driven by a combination of liquid and gas in which case the turbine exhaust fluid passes through a condenser 40 below the liquid level. After passing through the pump, the pressurised liquid is vaporised in a heat exchanger 50 and led to the turbine in an insulated pipe. If the turbine working fluid has a liquefaction temperature below the temperature of the liquid 18 then the pressurised working fluid passes through a pressure regulator fitted externally of the tank. The working fluid may be the vapour from the liquid in which case it is drawn off from the interior of the container (Fig. 4). Vapour from the container may pass into a separator (Fig. 3 not shown) or directly to the turbine 16 via a compressor 68. The exhaust from the turbine may pass into the line 22 and assist the flow of the effluent from the pump 10 in which case the vapour and liquid pass into the separator, the vapour passing to the compressor or back to the container and the liquid passing to a delivery line. In the event of a pump failure, or to assist the pump, compressed vapour may be passed through the delivery line. This pumping system ensures that vapour is returned to the container to counteract any pressure drop as the liquid level falls. In a modified form of this embodiment, (Fig. 4), the turbine exhaust is led directly to an accumulator 82, which also serves as a separator, and the line 70 has a by-pass 82 leading directly to the delivery line 22 the liquid being pumped direct to a separator 102. When the turbine 16 and pump 10 are inoperative the valve 78 and valves 84, 88 may be opened and liquid is pumped by vapour pressure into the accumulator 82, which has a relief valve 98. The liquid drains through lines 90, 92, 106 to a delivery reservoir.
