Jimmy L. Richards has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for the surface treatment of polymers for reinforcement-to-rubber adhesion
    Patent number: 5283119
    Abstract: This invention is directed to treating the surfaces of rubber-reinforcing materials with a gas plasma of O.sub.2 and CF.sub.4 to activate the surfaces to make them more receptive to adhesives. Optionally the surfaces of the reinforcing materials may be exposed to a polymerizing gas plasma such as a thio-carbon to coat the surfaces of the reinforcing material with substances that promote adhesion to rubber. The treated surfaces have been shown to adhere directly to rubber when vulcanized in the normal fashion.
    Type: Grant
    Filed: August 13, 1991
    Date of Patent: February 1, 1994
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Derek Shuttleworth, Syed K. Mowdood, Walter H. Waddell, Jimmy L. Richards, Eilert A. Ofstead, Jerry L. Brenner

  • Reinforcing element for elastomeric articles and elastomeric made thereof
    Patent number: 4546031
    Abstract: Reinforcing elements comprise a plurality of elongated metallic members, with substantially rectangular cross sections, having parallel longitudinal axes and at least one of the wide sides of each being contiguous with a wide side of another of said elongated metallic members. A single wrap member is helically disposed around the elongated metallic members such that each turn of the wrap filament member is spaced apart from the next adjacent turns of the wrap member. Elastomeric articles reinforced with these reinforcing elements are also disclosed.
