Patents by Inventor Louis G. Landry

Louis G. Landry 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 making a high temperature flexible unitary sleeving insulation
    Patent number: 5032199
    Abstract: The present invention discloses a glass covered electrical insulation having an inner lining of glass fibers coated with a flexible, high temperature, electrically insulating silicone polymer, the electrically insulating layer then has a second layer of glass fibers overbraided on it and bonded to it by the use of a heat treating process. A further teaching is the method of making the flexible sleeving and a method of use. The sleeving is particularly adapted for use in VPI processing and has superior flexibility as well as higher temperature capabilities than sleeving of the prior art.
    Type: Grant

    Date of Patent: July 16, 1991
    Assignee: Essex Group, Inc.
    Inventors: Louis G. Landry, Fabian Nunez
  • Heat shrinkable tubing article
    Patent number: 4915139
    Abstract: A heat deformable tube having a melt liner of noncross-liquid, thermoplastic material, such that upon heating to a temperature high enough to cause the tube to return to its original shape; the melt liner melts and encapsulates the substrate.
    Type: Grant

  • Highly flexible silicone rubber inorganic sleeving
    Patent number: 4704335
    Abstract: The present invention is directed toward a highly flexible, silicone rubber coated inorganic yarn based sleeving and a process for making the invention comprising an inorganic yarn sleeving, i.e., glass fibers, formed into a sleeving which is then coated with a highly flexible silicone rubber which has a Shore-A durometer reading of about 40 or less of the cured silicone material.
