  • Patent number: 9028955
    Abstract: An electrochemical cell comprises an ion permeable, liquid and vapor impermeable, membrane made by a solvent casting process. Two mutually insoluble polymers are cast together with the aide of mutually soluble co-solvents. The ion permeable membrane comprises a high molecular weight polyisobutylene polymer structural component. The linearized poly(acrylic acid) polymer ion conducting component comprises which is 4 wt % to 6 wt % of the membrane. The dried ion permeable membrane has a thickness of about 0.1 millimeters. The membrane is hydrated and used for transporting ions in an electrochemical cell. The cell demonstrates good reversibility, i.e. rechargability.

  • Patent number: 8141615
    Abstract: A method has been found for centrifugal casting engine cylinders. A mold is charged with molten aluminum alloy and particulate silicon monoxide having an average size of 0.01 mm to 0.04 mm. The mold is rotated at a velocity and period of time to distribute the particulate silicon monoxide on an inner cylinder surface. The mold is allowed to cool until the aluminum alloy solidifies. A casting is demolded characterized in a uniform inner cylinder surface of the particulate silicon monoxide in an amount of 25 volume % and thickness 1 to 5 millimeters. The engine cylinders are distinguished in resistance to wear. Cylinder liners show no appreciable wear for over 100,000 miles of use.

  • Patent number: 7833627
    Abstract: According to typical inventive practice, a first metallic material is poured into a mold including a bottom inside surface having regularly arrayed rises (truncated spherical convexities). The molten first metallic material cools and solidifies to include a surface correspondingly having regularly arrayed dents (truncated spherical concavities). The resultant “inner casting” is removed from and repositioned in the mold so that the inner casting's dent-laden surface faces upward. Ceramic spheres are placed in the dents. A second metallic material (having a higher melting point than the first metallic material) is poured into the mold with the inner casting and spheres in place. The molten second metallic material cools and solidifies as an “outer casting” surrounding the inner casting and the spheres. The resultant integral armor structure includes the inner casting, the outer casting, and the spheres, each sphere embedded partially in the inner casting and partially in the outer casting.

  • Patent number: 7025112
    Abstract: A metal-matrix material in the form of a carbide powder together with a sodium fluoride flux is deposited as a charge within a crucible for induction heating thereof to a flux melting temperature to thereby initiate pretreatment. The molten flux is spread over and covers powder particles of the metal-matrix carbide throughout, in response to stirring by rotation of an agitator during said flux melt heating within the crucible. The charge may be covered within the crucible by an air-purging blanket of argon gas during said heating. The powder fluxed charge is then cooled within the crucible before removal therefrom and sealingly packaged within aluminum soda cans or foil wrappings for future use storage. Such packaged charges are transferred from storage and introduced into a casting mold for enhanced centrifugal cast molding of metallurgical products, such as a metallic ring having an outer carbide bronze surface.

  • Patent number: 6116328
    Abstract: Alumina tiles within aluminum framing jigs are fixedly positioned by lock ns within an internally coated mold for centrifugal casting within a block of an aluminum alloy material. Such jigs and the tiles framed therein are coated with silver before casting to prevent aluminum oxidation by heating of the aluminum material to a molten state for deposit into the mold. Bonding of the tiles and framing of the jigs with the aluminum material being cast is also enhanced by such silver coating.
