Patents by Inventor Charles Vignal

Charles Vignal 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).

  • Resin impregnated substrate materials
    Patent number: 7585566
    Abstract: Building materials based on polyisocyanate-impregnated lignocellulosic substrates provide increased strength and water, fire, insect, and fungi resistance compared to prior art building materials. At the same time, such building materials exhibit an aesthetically pleasing surface and can, therefore, be used in consumer visible applications (such as furniture) as well as in consumer invisible (such as door frames and stiles) applications.
    Type: Grant
    Filed: March 30, 2005
    Date of Patent: September 8, 2009
    Assignee: Houston Advanced Research Center
    Inventors: John C. Colvin, Charles Vignal, Philippe Edouard Tissot, Larry Raymond Crowe

  • Resin-impregnated substrate, method of manufacture and system therefor
    Patent number: 6620459
    Abstract: The disclosed invention relates to polyisocyanate-impregnated lignocellulosic substrates having improved strength, water resistance and appearance, and also to methods and systems for producing such substrates. The polyisocyanate-impregnated lignocellulosic substrate are produced by impregnating a lignocellulosic substrate with an isocyanate resin, followed by polymerization of the isocyanate resin by applying a heated liquid to the impregnated substrate.
