  • Hybrid metal matrix composite chassis structure for electronic circuits
    Patent number: 5039577
    Abstract: A hybrid chassis structure including a layer of particulate reinforced metal and a layer of graphite fiber reinforced metal bonded to the particulate reinforced metal layer, wherein the overall thermal expansion, thermal conductivity and elasticity properties of the bonded hybrid structure are determined by controlling the properties of the respective layers.
    Type: Grant
    Filed: May 31, 1990
    Date of Patent: August 13, 1991
    Assignee: Hughes Aircraft Company
    Inventors: Albert C. Knoell, Timothy A. Loftin
  • Vehicular impact absorption system
    Patent number: 4118014
    Abstract: An improved vehicular impact absorption system characterized by a plurality of aligned crash cushions of substantially cubic configuration, each consisting of a plurality of voided aluminum beverage cans arranged in substantial parallelism within a plurality of superimposed tiers and a covering envelope formed of metal hardware cloth, and a plurality of cables extended through the cushions in substantial parallelism with an axis of alignment for the cushions adapted to be anchored at each of the opposite ends thereof.
    Type: Grant
    Filed: August 19, 1977
    Date of Patent: October 3, 1978
    Inventors: Robert A. Administrator of the National Aeronautics and Space Administration, with respect to an invention of Frosch, Albert C. Knoell, Abraham H. Wilson
  • Method of adhering bone to a rigid substrate using a graphite fiber reinforced bone cement
    Patent number: 4064566
    Abstract: A method of adhering bone to the surface of a rigid substrate such as a metal or resin prosthesis using an improved surgical bone cement. The bone cement has mechanical properties more nearly matched to those of animal bone and thermal curing characteristics which result in less traumatization of body tissues and comprises a dispersion of short high modulus graphite fibers within a bonder composition including polymer dissolved in reactive monomer such as polymethylmethacrylate dissolved in methylmethacrylate monomer.
