Abstract: Waste heat from paper mills, for example, is used partly as energy input to a heat motor, partly as energy input to a heat pump. The heat motor drives the compressor of the heat pump which means that no external high grade energy has to be supplied to drive the heat pump. The heat leaving the hot side of the heat pump can be utilized readily, directly or after heating of feed water, for example, possibly for vaporization thereof, for example, in the process that left the waste heat.

Abstract: A method, and apparatus for implementing the method, for simultaneously generating electrical power and producing refrigeration, utlizing an absorption/regeneration power cycle, and performing useful work with the heat rejected from the cycle. In the cycle, a working fluid is absorbed by a carrier fluid by an exothermic chemical reaction wherein the heat released is utilized to perform useful work. After absorption, the original fluids are regenerated by an endothermic chemical reaction with the required energy supplied by an external prime source. Surplus energy stored in the fluids after regeneration is extracted and utilized to generate electrical power, produce refrigeration, and provide internally required energy.

Abstract: A motive fluid composed of ethyl alcohol, distilled water and one of several buffering agents such as pyridine is disclosed. The fluid is compatible with aluminum, ductile iron, and mild and carbon steels.

Abstract: A system for powering a gas-sealed, flywheel-type turbine comprises a pair of pressurized storage tanks used alternately as a source and sink of Freon. A rotary valve, in a first position, directs liquid Freon from the first storage tank, functioning as a Freon source, to a boiler to produce super-heated Freon vapor. The super-heated vapor is used to directly drive the turbine, and the turbine exhaust vapor is converted back to liquid Freon in a condenser. The high pressure outlet of the turbine is used, via a capillary tube, to supply pressure for forcing the liquid Freon from the storage tank to the boiler. The condensed Freon is then directed, through the rotary valve, to the second storage tank functioning as a Freon sink. When the liquid Freon in the first storage tank is nearly depleted, boiling of the Freon is detected by a thermostatic bulb in thermal contact with the tank bottom.

Abstract: In a process for recovering the energy from a liquefied gas by evaporation in heat exchange with a cycle medium which is simultaneously cooled, said cycle medium being thereafter compressed, heated, subjected to engine expansion and recovered in a cyclical manner, wherein the improvement comprises operating the cycle so that the cycle medium remains in the gaseous phase throughout the entire cycle.

Abstract: Fossil fuels such as coal or oil are gasified by treatment under superatmospheric pressures with oxygen containing gasifying agents to produce a primary gas containing carbon monoxide and hydrogen. The primary gas is desulfurized and converted in increasing portion into methanol which is stored as the load on the power plant increases. An increasing proportion of the stored methanol is used in addition to desulfurized primary gas in the power plant as the load on the power plant increases.

Abstract: This invention relates to a system for generating power utilizing the elevation differences and available temperatures on the earth's surface, such as occurs in a mountainous region with a nearby valley or desert. The system includes heat rejection means, as for example, a condenser located at a higher elevation (a mountain top). Means for supplying heat to the system may be provided at a lower elevation (in a valley or desert region below). A geothermal source of heat, such as a hot spring, may be used. Power generation means are also provided in the valley and operatively communicated with the condenser on the mountain top and the heat supply means in the valley. Liquid flowing from the condenser to the power generation means at a relatively high pressure will drive the power generation means to create electrical energy and the liquid will be expanded, vaporized and cooled. The cooled vapor will absorb heat from the heat supply means and then be returned to the condenser on the mountain top.

Abstract: Trichlorodifluorobenzene is thermally stabilized particularly in the presence of engineering metals by contacting it, especially when at temperatures greater than about 200.degree.C, with solid alkaline earth carbonates or with alkali or alkaline earth borates in a sufficient amount. The method is particularly useful in Rankine-cycle engines using trichlorodifluorobenzene as the working fluid, when the stabilizer is contained in the boiler.
