摘要： A simple, substantially fail-safe jet engine bleed used for aircraft accessories is designed to have a small bleed port area for high power operating conditions of the engine and a larger bleed port area for lesser power operating conditions. The variable port can be made to vary its size in response to the power lever position, engine rpm, compressor bleed temperature or an engine pressure ratio.

摘要： A method and a mold for casting high temperature alloys having as an ingredient an element that reacts with the mold and core material and is thereby depleted during alloy solidification. A reservoir which is shaped to minimize depletion of the element is positioned above the article cavity in the mold to supply alloy to the top of the article cavity. As solidification proceeds, the molten alloy in the reservoir serves to enrich the solidifying alloy in the article forming portion of the mold with the depleted reactive ingredient.

摘要： In a multistage split compressor wherein the low pressure compressor has a plurality of stages on one rotor and the high pressure compressor has a plurality of stages on another rotor, the low pressure compressor is removable as a unit from the high pressure compressor by making the intermediate case in two pieces, one integral with the low pressure compressor case with an associated bearing for the low pressure rotor and the other integral with the high pressure compressor case also with an associated bearing for the high pressure rotor. By having these two pieces removably secured together, the associated compressor cases may be separated by removal of the attachment devices holding the cases together, and each case carries with it the associated bearing for the enclosed rotor.

摘要： An electrolysis cell system includes a compact electrolysis cell comprising gas diffusion electrodes on each side of an aqueous electrolyte retaining matrix. A portion of the hydrogen gas produced by the cell has water added thereto and is recirculated through a thermal exchange portion of the cell to remove waste heat from the cell and create a temperature gradient thereacross. The amount of water introduced into the recirculating gas stream is controlled to maintain a predetermined temperature of the gas stream emerging from the thermal exchange portion of the cell. The stream leaves the thermal exchange portion of the cell and reenters the cell in the gas space adjacent one of the electrodes. In a preferred embodiment the water added is sprayed into the recirculating gas stream and the heat laden stream emerging from the thermal exchange portion of the cell passes through a condenser where water vapor in the stream is converted to liquid and where heat is removed from the stream; the water vapor partial pressure of the stream reentering the cell is controlled by keeping the temperature of the stream leaving the condenser within a certain temperature range.

摘要： A cylindrical cathode is used as a vacuum chamber to permit sputtering by means of an rf potential on all sides of a workpiece located coaxially within the chamber. Both insulators and conductors may be used as target materials and as workpieces. Even deposition of the sputtered material on long or continuously fed workpieces is achieved by properly terminating the ends of the coaxial sputtering chamber with grounded chambers of larger diameter than the sputtering chamber and of sufficient length to thereby gradually reduce the plasma density along the axial direction to a relatively small value before reaching the end walls.

摘要： A laser mirror is constructed to provide a reflecting surface having a minimum amount of distortion while it is reflecting a high-power high-quality laser beam. The mirror is constructed having a backing plate made of a vitreous ceramic which has a very low coefficient of thermal expansion and a stiffness comparable to many metals. The reflecting surface is formed on a heat exchanger plate means which is bonded to said vitreous ceramic and has a manifold on each end. A coolant is passed through said heat exchanger plate means to reduce internal thermal response. The heat exchanger plate means can be formed from two preformed metal plates or one metal plate with a second plate being formed by plating. The invention herein described was made in the course of or under a contract or subcontract thereunder with the Department of the Air Force.

摘要： A purge valve for purging a fuel cell is automatically opened during a purge cycle after the fuel cell has expended a preselected number of ampere-hours. In one specific embodiment a plating current, proportional to the current provided by the fuel cell, causes platable material of an electrolytic cell to be transferred from the anode to the cathode thereof whereby the platable material on the cathode is proportional to the amperehours that have been expended by the fuel cell. When substantially all of the platable material has been transferred, the voltage of the electrolytic cell rises, thereby initiating the purge cycle. In another embodiment a current-to-frequency converter provides pulses to a binary counter in proportion to the current provided by the fuel cell whereby the accumulated count in the counter is proportional to the expended amperehours. When the accumulated count corresponds to the preselected number of expended ampere-hours, the purge valve is automaticallly opened.
