  • Patent number: 4146015
    Abstract: A solar pool heater is defined by a submersible tubular ring attached to the perimeter of a floating sheet. The ring is perforated to permit the entry of water within the ring to induce at least partial submersion. The submersed ring prevents overlapping of adjacent heaters and reduces the likelihood of the heaters being blown off the pool by wind. The sheet includes a plurality of captive air bubbles to provide a floatationcapability while simultaneously insulating the water surface from the ambient air. By developing the sheet from material transparent to at least a spectrum of the solar rays, the underlying water will become heated by the received radiant energy.

  • Patent number: 4143812
    Abstract: There is disclosed an apparatus and method for a thermosensitive safety valve to restrict a supply of fluid in a fluid delivery system when the temperature of the fluid reaches a predetermined temperature. A bimetal reed is utilized in which its unattached portion flexes outward from its normal, non-flexed position when the fluid temperature reaches a predetermined value into a flexed intermediate position with the mainstream of the fluid flow subsequently providing the pressing force for placing the unattached portion in a fluid restricting position. Furthermore, the reed may be reinstated in at least its flexed intermediate position so as to allow for subsequent fluid flow when the temperature of the same has been adjusted to a value less than the predetermined value of temperature.

  • Patent number: 4143643
    Abstract: A solar heat collector apparatus is disclosed which includes a reflective surface of appropriate geometric form for receiving the solar radiation and reflecting said solar energy to a tube which is mounted at a point to maximize the collection of radiant energy. The collector is formed by moulding a plastic insulation material in a container which is then covered by a reflective metal film. The surface forms a series of compartments or cells which may be parabolic in shape. The cells communicate with each other to form a continuous fluid circuit. A second circuit is provided within the tube located in each compartment of the collector. The insulation characteristics of the container have been maximized to avoid heat losses through conducting parts.

  • Patent number: 4142619
    Abstract: A dump valve mechanism for a wet clutch wherein the clutch includes a plurality of friction elements supplied with lubricating and cooling oil when the clutch is engaged and including a fluid pumping means as a part of a release mechanism, the release mechanism being axially movable to a position engaging a brake for a transmission input shaft. The dump valve is defined by a pair of annular surfaces which are opened and separated when the brake is engaged due to relative movement between parts of the release mechanism to divert the lubricant and cooling fluid from the clutch discs as the brake is applied to prevent viscous drag from providing unwanted drive between the friction elements when the clutch is disengaged.

  • Patent number: 4139085
    Abstract: A clutch of the single-plate dry-disc type is structured to include annular friction facings secured to opposite surfaces of a supporting plate of a clutch plate and a plurality of recesses or shallow grooves are defined in the surface of one of the annular friction facings. The shallow grooves extend from the inner periphery of the one annular friction facing and terminate short of the outer periphery thereof.Accelerated air streams are introduced from the exterior through the fly wheel into the plurality of grooves so as to aid in separation of the friction facing of the clutch plate from the engaging surface of a fly wheel as a result of a hydrodynamic force created by the air streams. Furthermore, slots are defined in the surface of the friction facing in addition to the grooves so as to provide discharge passages for powder which has been produced due to wear or attrition of the friction facings.

  • Patent number: 4137899
    Abstract: A plural stage solar radiation fluid heater comprises a housing having a top in which there is an array of lenses. Near the inside bottom of the housing, there is a first fluid conduit located at the foci of the lenses for absorbing primary solar radiation focused thereon. One or more additional conduits are interposed between the first conduit means and the lenses and are arranged to permit passage of the ray bundles from the lenses to the first conduit means. The arrangement is such that the intervening circuit means intercept secondary terminal radiation which is re-radiated from the next adjacent hotter conduit means.

  • Patent number: 4136674
    Abstract: A solar radiation energy collecting system for receiving the sun's rays and focusing them upon a central absorber. A plurality of plane mirrors are mounted in a circular array concentric with a vertical absorber tower, the azimuth angle of each of the mirrors being fixed in the array at the particular angle necessary for it to reflect rays from the sun upon the absorber tower. The mirror array is mounted upon a boat floating on a pond and the boat and mirror array rotated in synchronism with the daily apparent motion of the sun, so as to maintain the desired focusing of reflected solar radiation upon the absorber tower. In one simple embodiment the mirrors are rotated only in a horizontal plane about the vertical axis of the absorber tower, and the varying elevation angles of the sun cause the reflected solar energy to scan up and down along the length of the absorber tower as the sun moves from east to west each day.
