摘要： A closed cycle gas turbine engine has sealed therein a working medium, within a working chamber, a closed exhaust manifold, a gas recirculating path, and a plasma gas generator, with a turbine rotor rotating within the working chamber. High voltage pulses of very brief duration are periodically applied to the plasma gas generator, causing electrical discharges to form a plasma in said working medium, thereby producing high pressure motive gas. Resultant flows of high-pressure motive gas drive the turbine rotor, providing a high level of output power from the engine with no consumption of a fuel. The pressure of the motive gas is reduced in the closed exhaust manifold and recirculated to the motive gas generator through the gas recirculating path for next electrical discharge. The engine is suitable for driving a mechanism such as a vehicle, machine etc.

摘要： Apparatus for producing from a source of geothermal fluid that contains a mixture of high pressure steam, brine and noncondensable gases includes a heat exchanger for receiving geothermal fluid and transferring heat to water thereby vaporizing the same to produce steam. At least one power plant module is involved, the module having a steam turbine responsive to steam produced by the heat exchanger for producing work, a steam condenser containing an organic fluid and responsive to low pressure steam that exits the steam turbine for condensing the steam into a liquid and vaporizing the organic fluid. The module also contains an organic vapor turbine responsive to vaporizer organic fluid for producing work, and an organic vapor condenser responsive to the low pressure organic fluid that exits the organic vapor turbine condensing the organic vapor to a liquid that is returned to the steam condenser. The cooled geothermal fluid leaving the primary heat exchanger is conducted to a rejection well. Furthermore, an additional heat exchanger also can be provided, there being a first connection associated with both heat exchangers for selectively inserting the additional heat exchanger between the heat exchanger that receives the geothermal fluid and the injection well whereby the operation of the connection means may be coordinated with the operation of the power plant module.

摘要： A movement actuator includes an elongate filament made of a flexible material, and a strip of shape memory alloy disposed on the surface of one side of the filament. The shape memory alloy is responsive to actuation signals, heat or electrical signals, for changing its shape and when its shape changes, it causes the filament to move, i.e., bend, to accommodate the change in shape of the alloy. Also included is a signal supply device for selectively applying heat signals or electrical current to the strip of shape memory alloy to cause the alloy to change its shape and cause the filament to bend. Other patterns for the shape memory alloy could be disposed on the filament to cause other kinds of movements. For example, a helical pattern of the shape memory alloy about the filament would cause the filament to twist when the helical pattern were caused to shorten or lengthen.

摘要： A compressor for compression-evaporation cooling systems, which requires no moving parts. A gaseous refrigerant inside a chamber is acoustically compressed and conveyed by means of a standing acoustic wave which is set up in the gaseous refrigerant. This standing acoustic wave can be driven either by a transducer, or by direct exposure of the gas to microwave and infrared sources, including solar energy. Input and output ports arranged along the chamber provide for the intake and discharge of the gaseous refrigerant. These ports can be provided with optional valve arrangements, so as to increase the compressor's pressure differential. The performance of the compressor in either of its transducer or electromagnetically driven configurations, can be optimized by a controlling circuit. This controlling circuit holds the wavelength of the standing acoustical wave constant, by changing the driving frequency in response to varying operating conditions.

摘要： A process is disclosed whereby the recovery of process heat contained in NOx gases which have been generated by the combustion of ammonia in the ammonia oxidation step of a nitric acid production process is improved and whereby the recovery of the process heat takes place at a low temperature range. The process involves using process heat contained in NOx gases to evaporate and superheat liquid ammonia which is circulated in a separate loop, then expanding the superheated ammonia in a turbine to generate mechanical energy and subsequently pressurizing, reevaporating and resuperheating the ammonia.
