  • Patent number: 4344824
    Abstract: The disclosed invention is a solar still utilizing recirculating air driven by natural convection to evaporate pure water from saline water. The pure water evaporated into the air is removed by a condenser and the condenser also cools the air thereby causing its density to increase. The air density difference within the still, due to temperature differences, causes the air to flow in the desired pattern. This natural convection may be augmented by a fan or fans, if desired, to increase the output of the still. The same air is continuously circulated thereby reducing the thermal losses that occur when moist air is removed from the still. A recirculating pump is the only mechanical device required when the still is in the natural convection mode of operation.

  • Patent number: 4282862
    Abstract: Thin-line solar energy collectors are disclosed. The solar collectors of this invention function by internally redirecting incident light to the periphery of the collector where it is absorbed by a heat transfer fluid. This is accomplished by reducing the angular dispersion of the incident light with a high index of refraction glass, reflecting the light from wedge shaped surfaces and then transporting the light to the periphery of the collector module via total internal reflection. A typical collector is made up of a plurality of glass modules mounted in a frame through which the heat transfer fluid is circulated. Each individual glass module is a collector designed in accordance with this invention and is typically 3/8 inches thick by 11/2 inches wide by 3 feet long.

  • Patent number: 4218492
    Abstract: A meat product free of nitrite, nitrates, vegetable matter, or any similar preservative or filler matter is produced by grinding small pieces of pork belly to form an emulsion and adding a cure mixture; curing the resultant emulsion for a predetermined period on the order of not less than 1/2 hour or more than 6 hours and thereafter placing the cured emulsion into molds and slowly cooking the product at varying temperatures. The molded product is thereafter chilled to approximately the freeze point of distilled water, i.e., to F. The bacon product may be formed solely of natural ingredients and natural sweetners to eliminate a sugar normally employed in the processed product. If desired, the bacon product may be molded and marketed without cooking.
