Abstract: A flexible mirror device for providing a modified reflection of the body of a person is disclosed. The mirror device includes a first frame member and a second frame member disposed parallel to the first frame member and an upper and a lower frame member spaced from each other and extending between the first and the second frame members. A transverse shaft extends between and is rotatably secured relative to the first and second frame members. A first and second cam are rigidly secured adjacent a first and second end, respectively, of the transverse shaft and cooperate respectively with a first and second mirror support. A flexible mirror extends between the mirror supports. A central frame member which extends between the lower frame member and the transverse shaft is attached to the mirror such that rotation of the transverse shaft results in a changing curvature of the mirror.

Abstract: A binary vapor cycle method of electrical power generation is disclosed wherein two refrigerant fluids can be used to operate an apparatus for the generation of mechanical power as well as electrical power generation. This method, which is essentially a dual heat pump system, offers an approach to utilizing the advantages of two different refrigerants within a single apparatus. This advantage is particularly advantageous in the ulitization of low specific energy sources, such as two water sources which exist in close proximity to each other, but at different temperatures. Thus, water, which itself is a heat pump fluid, can be used as a means of transmitting heat energy to a second heat pump fluid, or refrigerant, without incurring the disadvantages of water, or water vapors, as a means to produce power, because of its high specific volume and low saturation pressures at low temperatures.

Abstract: An apparatus for desalinating ocean waters by distillation and furnishing electrical power, utilizes an evaporator, barometric leg conduits, a closed condenser, ocean water circulating circuits for circulating warm surface water to the evaporator and cool ocean water to the condenser and using the mass flow of vapors evolved from the evaporator to drive a prime mover which in turn drives an electrical generator. A portion of the electrical power so-generated is used to control the operation of respective pumps and valves in the apparatus. The liquid level of the condensate water is controlled in a barometric leg condensate outlet conduit. The system is also provided with a vacuum pump at least for initiating a reduced pressure and particle separator channel means is provided to prevent liquid entrainment in the condenser.

Abstract: A method of electrical power generation is disclosed wherein the energy source to operate the said electrical power generation apparatus is that energy existing between two fluid sources being at different temperatures and therefore at different energy levels. These fluid sources could be as divergent as warm underground crude oil as it is pumped from wells and the cooler atmospheric air above the said oil wells, or as intimately related as the warm water output from conventional and nuclear power generating plants and the cooling water source usually available to such generating plants. Warm water pumped from deep below the earths surface, geo-thermally heated, as the warm or hot source and surface water from lakes, oceans, rivers, etc. as the colder, or lower energy source provides an additional source of energy for the method of electrical power generation herein described.

Abstract: An apparatus is disclosed for concentrating fluid and for providing electrical power. The apparatus comprises an evaporator and a condenser interconnected by a conduit. A heat exchanger thermally couples warm liquid to the fluid in the evaporator. Means are provided for coupling a cool liquid to the condenser, thereby creating a mass flow of vapor from the evaporator to the condenser. A prime mover is interposed in the conduit for converting the mass flow of vapor into mechanical movement. An electrical generator is coupled to the prime mover enabling an electrical control to direct the output of the electrical generator for operating the apparatus and for directing excessive electrical energy produced by the electrical generator for external use.

Abstract: A low temperature purification system is provided which is particularly adapted for use to mechanically purify in a continuous operation solutions containing solids and dissolved substances. The purification system includes a solution supply means, and a centrifugal vacuum evaporator to which the solution to be purified is fed. Drive means is operatively connected to the evaporator for subjecting the solution within the evaporator to centrifugal acceleration and causes the solids in the solution to be displaced outwardly of the axis of rotation of the solution and the liquid of the solution to be displaced inwardly toward the axis of rotation. Outlet means is embodied in the evaporator for discharging the solids therefrom. The liquid as it is being displaced inwardly is simultaneously subjected to a reduced pressure to produce vapor which is conducted to a condenser means wherein the vapor is condensed to a substantially pure liquid.
