Patents by Inventor Wesley R. Tyler

Wesley R. Tyler 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).

  • Method of producing acicular metal crystals
    Patent number: 4268302
    Abstract: Improved processes and products based on the discovery that metal atoms in complex relationship with complexing agents can be used to moderate the formation of organic salt seed crystals which promote an exceptionally well-ordered acicular growth of organometallic salts such as oxalates of the metal. Some acicular, i.e., needle-like, products have particular utility for being reduced to ferromagnetic metal particles which retain a surprisingly large degree of acicularity and possess extraordinarily favorable properties for use in magnetic recording applications.
    Type: Grant
    Filed: July 2, 1979
    Date of Patent: May 19, 1981
    Assignee: Graham Magnetics Incorporated
    Inventors: Robert J. Deffeyes, Wesley R. Tyler
