摘要： A cryogenic freezer having a thermally insulated tunnel-like enclosure with an entrance and an exit and means for conveying products being frozen therethrough. Products are contacted with liquid cryogen at a region generally near the entrance and a blower located closer to the entrance than to the exit controls flow of cryogen vapor. Upstream and downstream baffles and dampers associated with blower are linked together for complementary movement to selectively regulate the upstream and downstream flow of vapor discharged from the blower. Additional blowers circulate the cold cryogenic vapor transverse to the direction of the conveying means. The temperature of vapor leaving the region of the entrance is monitored the orientation of the baffle and damper arrangement is adjusted in accordance with the temperature monitored. The food products can be contacted by liquid nitrogen in a reservoir facilitates cleaning and retards inefficient vaporization.

摘要： A cabinet freezer efficiently utilizes a liquid cryogen refrigerant in conjunction with a spiral conveyor which conveys a product load through a temperature gradient within the freezer. The freezer has a lower inlet and an upper outlet for the conveyor and food load thereon. The escape of cryogen vapors created in the freezer from the liquid cryogen is controlled such that at least about 80% of the vapors exit through the upper outlet which is at the warmest zone established as a part of the temperature gradient in the freezer.

摘要： A high pressure pump and delivery system mating to LNG storage and suited for natural gas powered trucks and buses, but also suitable for other cryogenic liquid fuels. The reciprocating pump is comprised of a liquid pumping portion and a vapor compressing portion, operating in concert so that it is possible to locate the pump above a source of saturated LNG and to reliably supply high pressure LNG. The delivery system provides a method of utilizing both the pumped LNG and the compressed NG in a Diesel type fuel injection system, and also to scavenge NG vapor from the LNG storage container so as to extend it's storage life. While especially useful for trucks and buses, the present invention is not limited thereto, as it is also useful for locomotives, automobiles and other vehicles designed to operate through combustion of natural gas, as well as stationary applications.

摘要： A liquid CO.sub.2 storage vessel system for user sites, which receives warm CO.sub.2 and then cools the liquid CO.sub.2 to temperatures below -25.degree. F. before further use. The cooled liquid CO.sub.2 can be at temperatures and pressures of near equilibrium conditions or at sub-cooled conditions. Cooling of the liquid CO.sub.2 is conducted by CO.sub.2 vapor removal from liquid CO.sub.2 ; and is independent from the CO.sub.2 use, so cooling can be conducted during both normal and off hours. The storage vessel can be safely filled from most existing delivery vehicles, and the previously cooled liquid CO.sub.2 in the bottom of the storage vessel can be prevented from mixing with the warmer being-delivered liquid CO.sub.2, so the temperature of the liquid CO.sub.2 immediately going to use is little effected by the delivery being conducted.

摘要： A refrigerated transport having an insulated enclosure and including a cryogen reservoir, e.g., high-pressure liquid cryogen or solid CO.sub.2. A plurality of thermosyphons associated with the walls and floor of the enclosure adjacent the interior skin intercept heat attempting to enter the enclosure. An intermediate heat sink draws the intercepted heat from the upper portions of the thermosyphons. The temperature of the heat sink is thermostatically controlled in a manner that the rate at which heat from the heat sink is absorbed by the cryogen is regulated to maintain the heat sink within a desired temperature range such that the thermosyphons will in turn maintain the enclosure and its product load at the desired subambient storage temperature.

摘要： Filling units for filling small tanks or the like with gasoline, kerosene, or other flowable materials which attach an inlet to such a tank. When the filling unit is in a fill position, a displacer section occupies a substantial volume within the tank. It allows the person filling the tank to supply the liquid until the tank will accept no more and the liquid reaches a predetermined level in a funnel portion of the filler. Thereafter, removal of the displacer section from the tank, as by sliding a section of the overall unit upward, allows the liquid in the funnel to enter the tank and fill the volume evacuated by the displacer section to complete the filling without any spillage. The overall unit may be removed from the tank each filling operation, or it may be designed to include a protective cap that fits over the upward-protruding portion of the unit, allowing the unit to remain mounted on the tank.

摘要： A system for storing electrical energy in the form of triple-point CO.sub.2 and then using such stored energy plus heat to generate electrical power. A reservoir of carbon dioxide liquid at about the triple point is created in an insulated vessel. Liquid carbon dioxide is withdrawn and pumped to a high pressure, which high pressure carbon dioxide is heated and expanded to create rotary power which generates electrical power. The discharge stream from the expander is cooled and returned to the vessel where carbon dioxide vapor is condensed by melting solid carbon dioxide. A fuel-fired gas turbine connected to an electrical power generator can be used to heat the high pressure carbon dioxide, and an ambient air stream flowing toward the gas turbine can be cooled by giving up heat to the high pressure carbon dioxide stream. The returning expanded carbon dioxide stream can be returned to a separate auxiliary vessel, and liquid carbon dioxide pumped from such auxiliary vessel to a main vessel wherein solid carbon dioxide is formed and then transferred to the auxiliary vessel.

摘要： Useful heat from an ice-maker is efficiently recovered and employed to heat water without any significant increase in the energy normally expanded in making ice. During ice-making, liquid refrigerant from a high-pressure receiver is expanded and supplied to an evaporator where ice-making occurs. Expanded refrigerant is returned to a compressor through an accumulator, and high-pressure vapor is condensed by heat-exchange with a circulating stream of water withdrawn from a storage tank. Condensed refrigerant is returned to the receiver through a restrictor. During the harvesting cycle, relatively warm, high pressure vapor from the receiver is fed to the evaporator, and any of it condensed to liquid therein is trapped in the accumulator. The compressor runs continuously throughout harvesting and ice-making, and any refrigerant trapped in the accumulator is used to subcool the high-pressure liquid prior to its expansion in the subsequent ice-making cycle.

摘要： A cabinet cooler or freezer which efficiently utilizes cryogenic refrigeration either with or without mechanical refrigeration. The freezer intermittently freezes relatively large batches of food by efficiently utilizing the natural expansion effect of a liquid cryogen, in combination with mechanical circulation by blowers, to create an overall circulation that efficiently removes heat from the food. A secondary circulation effect is induced, in a manner similar to the operation of a jet pump, which amplifies the circulation and allows CO.sub.2 to be employed with modulating valve control to achieve uniformly low temperature throughout the cabinet without snow build-up on the cabinet bottom. Some cabinet versions create a cyclonic circulation pattern about a vertical axis that is particularly effective.
