F24J 302

US Classification:

126424

Abstract:

A solar hot water generating system is disclosed which comprises a vertically pivotable heat exchanger automatically pivotable by means of a timer-actuated electric motor. The heat exchanger is fluidly connected to an insulated storage tank which retains the thermal values of the heated fluid. The system is adapted to provide hot water for domestic and industrial uses, such as heating, air conditioning, and the generation of electricity by operation of a turbine.

Abstract:

An RF-transparent sunshield membrane covers an antenna reflector such as a parabolic dish. The blanket includes a single dielectric sheet of polyimide film 1/2-mil thick. The surface of the film facing away from the reflector is coated with a transparent electrically conductive coating such as vapor-deposited indium-tin oxide. The surface of the film facing the reflector is reinforced by an adhesively attached polyester or glass mesh, which in turn is coated with a white paint. In a particular embodiment of the invention, polyurethane paint is used. In another embodiment of the invention, a layer of paint primer is applied to the mesh under a silicone paint, and the silicone paint is cured after application for several days at room temperature to enhance adhesion to the primer.
