Elizabeth M. W. Pincha 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).

  • Silica-enriched protective coating for hypersonic flight vehicles, and method of applying same, including field repair
    Patent number: 5431961
    Abstract: Coatings which protect the skin of hypersonic flight vehicles are disclosed. Silicide coatings, such as R512E, is used to minimize catalytic recombination of dissociated species, such as atomic oxygen and atomic nitrogen, thus, decreasing thermal and oxidative degradation. Also, disclosed is a method for maintaining the silicon content of protective coatings for the skin of hypersonic flight vehicles, including the steps of applying a prehydrated, polymerized sol of tetraethylorthosilicate to a coating, and firing, to produce an integral protective coating.
    Type: Grant
    Filed: August 3, 1988
    Date of Patent: July 11, 1995
    Assignee: The Boeing Company
