Patents by Inventor Jack M. Wheeler

Jack M. Wheeler 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).

  • Nickel-base alloy
    Patent number: 5017249
    Abstract: A nickel-chromium alloy exhibiting enhanced stress rupture strength and grain size stability at elevated temperatures up to about 1260.degree. (2300.degree. F.) due to the affirmative formation of M.sub.6 C carbide within the alloy. The alloy is especially useful for turbine and engine applications.
    Type: Grant
    Filed: July 10, 1989
    Date of Patent: May 21, 1991
    Assignee: Inco Alloys International, Inc.
    Inventors: Gaylord D. Smith, Curtis S. Tassen, Pasupathy Ganesan, Jack M. Wheeler
  • Nickel-base alloy
    Patent number: 4877461
    Abstract: The stress-rupture strength of a nickel-chromium-molybdenum-cobalt alloy is enhanced by reason of a special morphological microsctructure which in terms of carbides present is characterized by a predominant amount of the M.sub.6 C carbide.
    Type: Grant
    Filed: September 9, 1988
    Date of Patent: October 31, 1989
    Assignee: Inco Alloys International, Inc.
    Inventors: Gaylord D. Smith, Curtis S. Tassen, Pasupathy Ganesan, Jack M. Wheeler
  • High nickel chromium alloy
    Patent number: 4784830
    Abstract: An oxidation resistant nickel-chromium based alloy possessing good stress rupture characteristics at elevated temperature and, in addition to nickel and chromium, containing correlated percentages of aluminum, titanium, nitrogen, carbon, etc.
    Type: Grant
    Filed: June 8, 1987
    Date of Patent: November 15, 1988

    Inventors: Pasupathy Ganesan, Gaylord D. Smith, Curtis S. Tassen, Jack M. Wheeler
  • Nickel-chromium alloy of improved fatigue strength
    Patent number: 4765956
    Abstract: Nickel-chromium alloys consisting essentially of from 30-75 nickel, 12-30% chromium, up to 10% molybdenum, up to 8% tungsten, up to 15% cobalt, up to 5% of niobium and/or tantalum, titanium plus aluminum up to 5%, and carbon nitrogen and silicon in correlated percentages to thereby improve low cycle and thermal fatigue strength, the balance being from 0 to 50% iron.
