Abstract: A confined gaseous mixture of carbon dioxide and nitrogen is irradiated with a carbon dioxide laser which excites a significant portion of the gas to vibrational energy levels, thereby reducing the translational energy and therefore the temperature of the gas. The gas is adiabatically compressed, and then allowed to relax so that the temperature of the compressed gas increases. The high temperature, compressed gas is then expanded through a turbine or in a cylinder which drives an external device, such as vehicle propulsion apparatus or an electric generator, thereby to perform work. The process may occur in engines having one or more closed cylinders, or in turbocompressors.

Abstract: A calcium carbide based power system for stationary and mobile power plants. The carbide is reacted with water to create heat and acetylene, with the acetylene then being burned to heat a boiler for providing steam to a steam expander. The exhaust of the steam expander is condensed and pumped back into the boiler, first being pre-heated by a heat exchanger using the heat in burner exhaust gas and then in the carbide-water reactor to further pre-heat the boiler makeup water (steam) and to cool the reactor.

Abstract: An air-handler includes an AC induction motor that drives a blower to move air across a heat exchanger. A switch system selectively determines whether the blower motor operates at its rated full speed or at a reduced speed. For full speed operation, the switch system couples an AC supply at a nominal line frequency directly to the blower motor and bypasses an inverter. For reduced speed operation, the switch system couples a lower frequency output of the inverter to the blower motor. The blower is operated at a reduced speed during a pre-run dehumidification mode, a post-run heat recovery mode, and/or an electronic air-cleaning mode. The switch system allows the rated current capacity of the inverter to be substantially less that the rated full load current of the blower motor.
