Donald T. Rorabaugh 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).

  • High density-high strength uranium-titanium-tungsten alloys
    Patent number: 4966750
    Abstract: A uranium-base alloy consists essentially of the formula U.sub.bal --Ti.sub.x --W.sub.y, where x ranges from about 0.5 to 1.0 and y ranges from about 0.25 to 2.0. The alloy exhibits high strength, good ductility and high density and is especially suited for use in ballistic penetration cores.
    Type: Grant
    Filed: June 26, 1989
    Date of Patent: October 30, 1990
    Assignee: Allied-Signal Inc.
    Inventors: Jerry C. LaSalle, Ravi Batra, Donald T. Rorabaugh
  • High density, high strength uranium-titanium-hafnium alloys
    Patent number: 4935200
    Abstract: A uranium-base alloy consists essentially of the formula U.sub.bal -Ti.sub.x -Hf.sub.y, where "x" ranges from about 0.5 to 1.0 and "y" ranges from about 0.5 to 5.0. The alloy exhibits high strength, good ductility and high density and is especially suited for use in ballistic penetrator cores.
    Type: Grant
    Filed: June 26, 1989
    Date of Patent: June 19, 1990
    Assignee: Allied-Signal Inc.
    Inventors: Jerry C. LaSalle, Ravi Batra, Donald T. Rorabaugh
  • Fiber array reinforced kinetic energy penetrator and method of making same
    Patent number: H343
    Abstract: An improved fiber reinforced penetrator rod for a kinetic energy projectile aving enhanced penetrating strength is disclosed herein. Embedded in a matrix medium of depleted uranium, or liquid phase sintered tungsten, are long fibers of tungsten-hafnium-carbide which are knitted into a continuous weave over the entire length of the fibers. This prevents splaying open or splitting of the front end of the fibers, and hence of the whole penetrator rod front end, upon impact, penetration, and receiving of the compressive forces upon hitting an armor target.
