摘要： A refrigerator (10) includes a vacuum cabinet (20) which includes a vacuum compartment (42) and an open top drawer (34) in the vacuum compartment. When the refrigerator door is closed, a rotary spool (75) of the air control valve (70) is moved to a position to recirculate air from the vacuum compartment through the vacuum pump (65) back into the vacuum compartment so as to pre-chill the contents of the vacuum compartment. Later, while the refrigerator door is still closed, the air control valve is shifted so that the vacuum pump (65) draws air from the vacuum compartment until a predetermined low air pressure is detected in the vacuum compartment, whereupon the operation of the vacuum pump terminates. When the refrigerator door is opened, the valve spool (75) rotates to vent the vacuum compartment to the atmosphere, thereby equalizing the pressure within the vacuum compartment to atmospheric pressure and allowing the open top drawer of the vacuum compartment to be opened.

摘要： A temperature controlled cryogenic package system for efficiently and precisely monitoring and controlling the operating temperature of a high temperature superconductor circuit placed on a substrate. The cryogenic package system comprises a heating element formed on the same substrate as the high temperature superconductor circuit, a control circuit capable of activating and deactivating the heating element, and a temperature sensor placed in thermal proximity to the high temperature superconductor circuit. The temperature sensor monitors the operating temperature of the high temperature superconductor circuit, and conveys temperature information to the control circuit. The control circuit activates or deactivates the heating element according to the warming or cooling effect that is necessary in order to maintain the high temperature superconductor circuit within a predetermined temperature range, where the range of temperature fluctuation is within plus or minus 0.1 K of a predetermined temperature.

摘要： An apparatus for cryogenically freezing tissue specimens includes a linear motion platform and a pair of rotary motion platforms. The rotary motion platforms can be used alternatively with respect to the linear motion platform and a mechanism is provided to automatically trigger the linear motion platform for movement and to reset the linear motion platform when the rotary motion platforms are placed in covering relationship with or removed from covering relationship with respect to the linear motion platform. Cryogenic fluids are supplied to tissue receiving cryogenic discs on the various platforms through flexible plastic tubing. The tubing that supplies cryogenic fluid to the rotary motion platforms is constructed so as to form a series of loose loops in conjunction with tails that are mounted over a central rod to allow movement at cryogenic temperatures. The apparatus also includes elevation pylons for maintaining specimen receiving plates on the linear motion platform in a raised position prior to placement of the specimen in conjunction with the platform. Heaters and control systems are provided with respect to sets of the cryodiscs to allow an operator to select between using all of the discs or only groups of them.

摘要： The delivery system of the invention consists of a pair of LNG fuel tanks mounted on a vehicle. A solenoid valve associated with each tank allows the vehicle operator to select the tank from which LNG is to be delivered to the engine. An automatic override system is provided whereby if the pressure in the non-selected tank rises above a predetermined level, the operator's tank selection is overridden and gas from the non-selected tank is used until the pressure falls below the predetermined level. This override system eliminates the need to vent gas to the atmosphere to avoid pressure building up and thereby eliminates waste of the LNG. Each tank is also provided with a pressure building capability such that the gas will always be delivered to the engine with sufficient pressure. The system is designed such that LNG from a stationary low pressure storage tank can be delivered at high pressure to refuel the tanks. Finally, a variable insulation barrier is provided in the fuel tanks to minimize heat transfer between the LNG and gas head.

摘要： In a "permanent" magnet system based on high-temperature superconductors, a superconducting magnet is cooled to a temperature below its critical temperature with a cooler. The magnet is coupled to a cold body of solid nitrogen which is insulated to minimize heat input to the system. The superconducting magnet is energized to generate a magnetic field and the cooler is removed. Unlike conventional superconducting magnets in which the magnet operating temperature is maintained at a fixed point, in the system of the present invention the operating temperature is allowed to rise from an initial value of approximately 20 K to as high as 63 K (the melting point of nitrogen), enabling operation over an extended period without the aid of direct cooling. The superconducting magnet is recooled periodically to lower its temperature to approximately 20 K. The magnetic field is maintained and the system is fully operable during the recooling process. For large systems, the time period between recooling cycles can exceed one year. This cryocoolerless lightweight "permanent" magnet system is particularly effective in on-board or portable applications which would benefit from the absence of a cumbersome cryocooler.
