Douglas E. Edwards 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).

  • System for coating a substrate
    Patent number: 6887314
    Abstract: A method and apparatus for coating sheet material with thermoset material. In certain embodiments, first and second different induction furnaces are provided, with the coated sheet first proceeding into and through the first furnace, and then into and through the second furnace. The first furnace may be maintained at a temperature less than the second furnace, so that out-gassing of volatile materials is achieved in the first furnace and thereafter heightened cross-linking conversation rates are achieved in the second furnace at higher temperatures.
    Type: Grant
    Filed: June 17, 2003
    Date of Patent: May 3, 2005
    Assignee: Material Sciences Corporation
    Inventors: Douglas E. Edwards, Mark R. Monterastelli
