  • Patent number: 5344597
    Abstract: A method and apparatus for forming sheets of a first material, such as a metal, plastic, rubber, or the like, having a primary tank for heating a second molten material and containing the second molten material to form a surface upon which the first material is floated in a molten state. The temperature of the second molten material is maintained below the melting temperature of the first molten material, and the second molten material has a higher specific gravity than the first molten material. Thus, the first molten material floats upon the surface of the second molten material while it solidifies into a sheet of material, which is then withdrawn from the surface of the second molten material. A hood is disposed over the primary tank to remove fumes and vapors which, when removed, are discharged into water where they condense.

  • Patent number: 4832262
    Abstract: A heat exchanger member contoured to fit along one side of an exhaust pipe is retained in place on the exhaust pipe by clamps. In one form of the invention the exhaust pipe forms a part of the heat exchanger reservoir in which case leak preventive adhesive secures the heat exchanger member to the pipe. The heat exchanger member is provided with intake and discharge tubes, the intake tube connected to the pump of an existing windshield washer assembly and discharge tube being connected, through a manifold to the discharge nozzles adjacent to the windshield. In another form of the invention, the discharge from the heat exchanger is directed along a header or manifold of a nozzle assembly adjacent to and for washing the rear window of the automobile. In still another form of the invention, the heat exchanger forms an essentially closed reservoir so that the exhaust pipe does not come in contact with the fluid flowing therethrough.

  • Patent number: 4783217
    Abstract: A method and apparatus for producing spherical objects is disclosed, the apparatus having a reservoir filled with a relatively dense molten material, the reservoir being heated and hydraulically pressurized to maintain the molten state of the dense material. A second molten liquid, of lesser density and higher melting point is injected into the reservoir, the pressure and surface tension acting to force the injected material into a spherical form and the melting point difference acting to solidify the injected material.

  • Patent number: 4455302
    Abstract: Medical Protein Hydrolysate is produced from the feet of young freshly killed poultry or other young freshly killed animal sources of protein which are sufficiently immature that the resulting protein lacks antigenic properties. The protein, thus produced, is an extract of polypeptides and amino acids having as little biological disruption as possible. It is in the form of a powder or a gel, each of which is suitable for topical application to living cells of animals and humans for aiding in healing. The process of production of the Protein Hydrolysate includes treating the washed and comminuted poultry feet or other source of protein with a dilute acid, preferably acetic acid, and drying under low heat conditions the resulting solution to a powder or to a gel. The process of using the Protein Hydrolysate including periodic topical application to a traumatized (wound) area. In the event that treatment is to be below the surface, an aqueous solution of the protein can be injected into the area to be treated.
