  • Patent number: 4232658
    Abstract: A solar collector panel and method of making same are disclosed. The solar collector panel has four layers of fiberglass mat which are each saturated with a catalyzed liquiform resin. Between the first two layers, unimpregnated Kraft honeycomb paper having an open cellular structure is placed so as to form a resinated honeycomb core between these first two layers. A black gel coat is sprayed onto the second layer of resin-saturated fiberglass mat and a plurality of copper tubes are then placed onto the black gel coat so as to be bonded in heat-transfer relation thereto. The third layer of resin-saturated fiberglass mat is draped over the copper tubes so as to insulate them. A second layer of Kraft honeycomb paper is then placed between the third and forth layers of resin-saturated fiberglass mat, and a clear gel coat mixed with an ultraviolet inhibitor solution is rolled out over the top of the solar collector panel to partially screen out ultraviolet rays.

  • Patent number: 4197060
    Abstract: A heat-powered water pump including a flexible diaphragm as the pumping element with a volatile liquid as a working fluid. The flexible diaphragm is enclosed within a vessel and isolates the working fluid from the water to be pumped. One-way valves control the direction of water flow through the pump. A U-shaped siphon tube acts as a temporary reservoir for the pumped water and is siphoned empty after being filled. A portion of the water siphoned from the U-shaped siphon tube is recirculated through the vessel in heat exchange relationship with the working fluid to condense the working fluid. A reservoir of warm water is maintained in thermal contact with the flexible diaphragm to minimize condensation of the working fluid by thermal contact with the water through the diaphragm.

  • Patent number: 4195485
    Abstract: A distillation/absorption engine including apparatus for utilizing a lower boiling point, working fluid and a higher boiling point, absorption fluid, the absorption fluid having a relatively high degree of absorptivity for the working fluid. The apparatus includes a distillation column for separating the working fluid from the absorption fluid and a condenser/storage system for storage of the separated working fluid which is condensed and stored as a condensate. An absorption reboiler is used to revaporize the condensed working fluid. The revaporized working fluid is superheated in a superheater before producing mechanical energy in a mechanical expansion engine such as a turbine or the like. Thermal energy for the absorption reboiler is obtained from the heat of absorption generated by absorbing with the absorption fluid the spent working fluid from the mechanical expansion engine. Absorption of the spent working fluid also lowers the backpressure for improved efficiencies.

  • Patent number: 4185616
    Abstract: An improved apparatus and method for absorbing solar energy, the apparatus providing a sealed envelope having a transparent upper panel with a solar energy absorbing panel thermally isolated against convective and conductive heat losses by a partial vacuum in the sealed envelope. The transparent panel has an upwardly extending curvilinear surface which increases its strength characteristics against the pressure differential between the ambient and the partial vacuum inside the envelope. Support structure is also provided in conjunction with the apparatus to place the periphery of the transparent panel under constriction to compensate for tensile stresses imposed thereon by the pressure differential. The inside surface of the transparent panel and the absorber panel are selectively coated with an infrared reflective surface to reflect and reduce losses of infrared radiation emitted by the absorber panel.

  • Patent number: 4182441
    Abstract: A pipe hanger/snubber for supporting and/or protecting high-pressure piping and the like against damage by seismic, vibrational, and thermal shocks to the mechanical integrity of the piping system. The apparatus includes a sealed snubber cylinder containing a non-Newtonian fluid as the hydraulic fluid medium. A working shaft extends completely through the snubber cylinder. A shaft-mounted, perforate load nozzle is moved longitudinally through the non-Newtonian fluid in the snubber cylinder to thereby dissipate the shock forces. Shaft-engaging seals at each end of the snubber cylinder inhibit leakage of the non-Newtonian fluid from the snubber cylinder. Selectively, reservoir apparatus containing non-Newtonian fluid are provided adjacent at least one seal to compensate for leakage, if any, of the non-Newtonian fluid through the seal.
