  • Patent number: 4042085
    Abstract: A friction coupling which utilizes a friction plate composed of high modulus asperities incorporated into a reboundably compressible elastomeric matrix for selective rotational engagement with a relatively noncompressible reaction plate between which is directed a flow of fluid with the asperities hydrodynamically wedging such fluid into a relatively thin load supporting film between the asperities and the reaction plate which film absorbs substantially all of the energy of engagement in the shearing effect of the fluid during relative rotation of the plates.
    Type: Grant

  • Patent number: 4036668
    Abstract: Fluoroelastomers, including ultra high temperature, thermally stable fluoroelastomers, are bonded to a metal backing member by (a) compounding the fluoroelastomers with CaO, (b) curing the fluoroelastomers in contact with a pretreated surface of the metal member, and (c) postcuring the fluoroelastomers/metal unit at elevated temperatures.
    Type: Grant
    Filed: March 17, 1975
    Date of Patent: July 19, 1977
    Assignee: Caterpillar Tractor Co.
    Inventor: William D. Brandon
  • Patent number: 3982983
    Abstract: Fluoroelastomers, particularly ultra high temperature thermally stable fluoroelastomers are bonded to a metal substrate by forming a roughened bonding surface on one side of the substrate, controllably oxidizing the substrate at a temperature sufficient to cause the formation of an oxide coat on said bonding surface but below the tempering temperature of the substrate, adjusting the substrate to a temperature above the softening temperature of the fluoroelastomer, adhering the fluoroelastomer which includes a minor amount of an alkaline earth oxide dispersed therein, heated to a temperature sufficient to initiate curing thereof, directly onto said bonding surface, and expeditiously compressing said fluoroelastomer between said bonding surface and a mold face maintained at a temperature closely adjacent to the temperature of the substrate.
    Type: Grant

    Assignee: Caterpillar Tractor Co.
    Inventors: John C. Abraham, Gary L. Grebner, William D. Brandon, John Jero
