Barry J. Berkowitz 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).

  • Alloys having improved resistance to hydrogen embrittlement
    Patent number: 4591393
    Abstract: Certain high strength alloys lacking resistance to hydrogen embrittlement are cold worked and heat treated utilizing critical preselected conditions to result in a unique alloy having increased resistance to hydrogen embrittlement without unacceptable loss of strength. It is theorized that this unexpected improved resistance correlates with the concentration of certain elements, such as phosphorus and sulfur as impurities on the crystallographic boundary surfaces of the alloy.
    Type: Grant
    Filed: March 1, 1978
    Date of Patent: May 27, 1986

  • Low temperature heat pipe employing a hydrogen getter
    Patent number: 4586561
    Abstract: A heat pipe is described for use under low temperature conditions employing preferably ammonia as the heat transport medium and a hydrogen getter material, preferably being a zirconium intermetallic alloy, capable of non-reversibly gettering hydrogen gas in the presence of ammonia and air.
    Type: Grant

  • Superalloys having improved resistance to hydrogen embrittlement and methods of producing and using the same
    Patent number: 4245698
    Abstract: Cold-worked superalloys having improved resistance to hydrogen embrittlement are disclosed. These new superalloys are nickel- or cobalt-chromium-molybdenum superalloys and possess improved resistance to hydrogen embrittlement rendering them useful in deep sour gas wells.
