Abstract: A cooling system is provided for supplying cryogenic cooling fluid to a thermal load. The system includes a cryogenic refrigeration system, a cryogenic cooling fluid coupled to the thermal load, and a primary power supply for providing power to the cryogenic refrigeration system. A backup power supply provides power to the cryogenic refrigeration system in the event that the primary power supply is unable to provide sufficient power to the cryogenic refrigeration system.

Abstract: Single-crystal diamond consisting of isotopically pure carbon-12 or carbon-13 has been found to have a thermal conductivity higher than that of any substance previously known, typically at least 40% higher than that of naturally occurring IIA diamond. It may be prepared by a method comprising comminution of diamond of high isotopic purity, such as that obtained by low pressure chemical vapor deposition employing an isotopically pure hydrocarbon in combination with hydrogen, followed by conversion of the comminuted diamond to single-crystal diamond under high pressure conditions.

Abstract: An inductor uses high temperature superconductors in order to obtain high Q for high frequency operation. The superconductors are applied as thin films to substrates. In some embodiments, superconductor thin films are applied to opposite sides of the same substrate. Superconductive thin films are applied outside the magnetic field establishing superconductive thin films in order to shield against leakage of the magnetic field beyond the inductor. The inductor is connected to a capacitor to realize a resonant circuit used in a power conversion system.

Abstract: A process for cleaning fouled separation membranes such as ultrafiltration, reverse osmosis, and microfiltration membranes is provided comprising: removing a separation membrane having a fouled surface from operation; effecting reaction on the fouled surface of said membrane of an inorganic peroxide and an alkali metal or alkaline earth metal hypohalite; and thereafter, substantially removing the foulant and the reaction products thereof from the membrane surface.

Abstract: An ultrafiltration system has a plurality of filter modules coupled in a parallel arrangement. The flow rate at the output of each filter module is detected. When the flow rate of a given module falls below a threshold value, that module is disconnected from the ultrafiltration system and automatically coupled into a regeneration circuit so that the filter module can be cleaned. Once regenerated, the filter module is recoupled into the ultrafiltration system. If the regeneration circuit is already in use when a filter module is detected to be in need of regeneration, that module is placed in a queue for regeneration once the regeneration circuit is free, and all other modules previously placed in queue have been regenerated. While awaiting regeneration, the filter modules are kept in service in the ultrafiltration system.

Abstract: A sand molded plant receptacle, specifically a flowerpot, made of a non-wetting resin-bonded sand characterized by smooth inside and outside surfaces, a density of about 100 lbs. per cu. ft., a permeability of about 60 to 160, and by being impervious to water and pervious to air. A method of making a sand molded flowerpot which comprises blowing resin-coated sand under pressure into a closed, heated mold.
