Abstract:
A solar heater for heating water passing therethrough. The heater includes a corrugated radiant-heat absorbing panel slanted parallel to the corrugations, a liquid-delivery manifold-pipe along the upper end of the corrugated panel and having discharge apertures in operative registration with the upper ends of the upwardly-facing troughs of such corrugations, and a slotted envelope-protector and liquid-discharge pipe extending across and mounted to the lower edge-zone of the corrugated panel, with the lower edge-zone thereof extending into and tightly fitted in the slot of the pipe;-- the upper liquid-supply manifold-pipe and the lower liquid-discharge pipe and the corrugated panel therebetween being fully enveloped by and sealed within a flexible envelope formed of pliable weather-resistant plastic sheeting, at least the top panel of which envelope is highly transparent.
Abstract:
A solar energy collecting device comprising a hollow plastic panel as the heating element, said panel having opposite ends converged to provide tubular end portions each being inserted into and axially slidably supported by a tubular stud of a header. A pair of headers being provided at opposite ends of said hollow plastic panel.
Abstract:
Disclosed is a textile damping material which has the structure of a flexible, three-dimensional, textile spacing structure (50) which is stable in respect of shape. The spacing structure (50) has an upper layer portion (7) and a lower layer portion (9) which are made up of single-thread or multi-thread yarn, wherein the two layer portions (7, 9) are spaced from each other and connected to each other by elastic pile threads (8).Also disclosed is an impact and water absorbing mat for motor vehicles and a tee-off golfing mat, each obtained by use of the textile damping material. The tee-off golfing mat has a damping layer (10).
Abstract:
A barrel-shaped solar roofing element consisting of a portion of a conical-shaped panel of a material such as PVC plastic formed by injection molding adapted for receiving an impingement of solar energy upon an outer surface thereof and constructed of insulative material having a relatively thin dimension, a passway extending throughout the panel for conduiting a heat exchanger fluid, the passway having a male coupling at one edge of the panel and a female coupling at a generally distal edge of the panel and constituting a fluid circuit, or at least a portion thereof, each of the male coupling and female coupling formed for interlocking with a complementary or mating kind of coupling of an adjacent panel.
Abstract:
A solar heating system for heating fluid enclosed in a waterproof, heatable flexible bag held in a support which can be a cavity in the earth, insulated from ambient temperatures by alternate layers of transparent flexible gas bags and liquid bags disposed above the heatable bag. An upper weight bag filled with liquid applies weight down against the heatable bag to apply pressure on it to raise the boiling point of the liquid therein. A heat exchanger receives hot fluid from the heatable bag to produce hot gas such as hot freon under pressure to operate a turbine. The turbine can deliver electricity for electrical power for producing hydrogen and oxygen gases, for heating and for other uses including electrical power for municipalities.
Abstract:
A solar energy absorber module having a molded top sheet of translucent plastic material and a molded bottom sheet of solar absorbing plastic material bonded together by circular bond indentations in the body thereof spaced from each other a distance equal to the diameter of the circular bond thereby forming a plurality of convex lens-like elliptical sites for augmentation of solar energy and a plurality of longitudinal tortuous sinusoidal channels in communication with a header at each end of the module for passage of working fluid therethrough.
Abstract:
A passive solar heating liquid storage tank is formed of multiple thin sheets of thermoplastic or thermoset material to provide a lightweight, inexpensive and high volume tank. The multiple sheets have a plurality of parallel undulations or corrugations transverse to their surfaces. The undulations form spacial wave trains of given amplitude and frequency so that when their peaks are secured together they form generally parallel circular tubes. One of the pair of sheets has a third sheet secured to its surface. The third also has undulations in its surface with spacial frequency at least as great as the frequency of the wave train of the pair of sheets. Peaks of the third sheet are then secured to exterior peaks of the pair of sheets. Such construction forms a tank having the strength of parallel cylindrical tubes but with total volume approaching that of tubes having a rectangular cross-section. In this way a lightweight tank with high volume and strength to resist structural beam flexure relative to the surfaces is formed. Such construction is particularly suitable for passive solar water heating installations at inaccessible locations over long periods of time, such as on the roof of a building.
Abstract:
A solar energy collector comprises plastic sheets superposed to delimit a tube for circulation of a gas to be heated by contact with radiant heat absorbing means in the collector, and an insulating chamber communicated with the tube by means of at least one aperture. Separate inflation means for the insulation chamber is not needed as the heat transfer gas inflates both the tube and the insulation chamber, rendering the collector less liable to damage by overheating upon deflation of the tube.
Abstract:
A method of maintaining the temperature of a solar heating panel with glazing below about 220.degree. C. utilizes convention cooling, where it is essential to the success of the method that the glazing be at least two inches above the upper surface of the collector. A panel of unitary construction of essentially the same plastic material which is an embodiment of the method can withstand the normal operating conditions to which such panels are subjected without thermal degradation of the plastic nor danger of rupture attending loss of physical integrity at excessive temperatures.
