Abstract: A fuel-efficient method and apparatus for the generation, actually re-generation, of ejecting steam used in a steam ejection system to evacuate process vapor from an enclosed space. In the method, all of the ejecting steam is not generated continuously in a boiler, but a predetermined quantity of steam is reused by continuous mechanical recompression, without intervening condensation, in a returning cycle while alternating between a pressure low after ejection (i.e. expansion) and a pressure high after recompression, whereas the evacuated vapor is branched off from the ejecting steam cycle after ejection and condensed. Parts of the condensate are reconverted to additional steam by heat exchange with all or part of the superheat and friction heat contained in the recompressed ejecting steam and/or by heat exchange with the exhaust and cooling system of a heat engine serving as a prime mover for the compressor.

Abstract: This invention relates to a steam turbine system which utilizes a unique heat-absorbing lens-shaped heating plate and boiler for the production of steam.

Abstract: A fluid delivery control device for regulating fluid delivery by a pump to the heated vaporization chamber of a steam curling iron through a fluid conduit provided with a spring biased valve in response to the temperature of a heating element in the chamber includes a bimetallic disc in the chamber having the property of changing its shape when heated to a temperature corresponding to the minimum temperature required of the heating element for vaporizing the fluid. A fluid delivery tube through which the fluid is delivered from conduit to the chamber has one end adjacent to the valve and the other end attached to the disc for movement therewith. When the chamber is below the minimum temperature, the disc pushes the one end of the tube against the valve to hold it closed and prevent delivery of fluid through the tube to the chamber.

Abstract: A power generation system having a low pressure source of water, means connected to the source of water for pressurizing the water to a substantially higher pressure, means for forming steam from the pressurized water, and a steam turbine for deriving mechanical motion from the steam. The pressurizing means uses first and second chambers of variable volumes. Valve means are associated with the first and second chambers so that water flows into the first chamber when its volume is expanding but water is not allowed to flow into the first chamber when its volume is contracting. Likewise, the valve means are utilized so that water flows into the second chamber when its volume is expanding but water is not allowed to flow into the second chamber when its volume is contracting. Furthermore, valve means are associated with the first chamber to allow pressurized water to flow out of the first chamber when its volume is contracting.

Abstract: A steam generating device comprising a metallic evaporation body of desired shape, such as a dish-like shape, a cylindrical shape and so on; and a thin layer provided on the surface of the body, the layer having a rough surface and a water absorption ability. In use, the device is heated and, then, a little water is intermittently supplied on the thin layer, so that the water is instantaneously evaporated.

Abstract: A heat storage unit using salt or a salt mixture. Heat is extracted from the unit by converting water to steam and a series of pipes is provided extending to different depths in the salt. The pipes extend to different heights at the top of the unit so that water first overflows into the pipe extending the shortest distance into the salt. This results in the salt in the unit solidifying from the top downwards, thereby obviating problems caused by molten salt migrating to spaces at the foot of the container caused by contraction of salt on solidification. A heating system uses several such units with electrical heating between the units and pumped circulation of the condensate from the generated steam. An alternative system uses steam generated in such units selectively to drive a turbine for refrigeration equipment in a cooling system or to heat the heat exchange medium in a heating system.
