Patents by Inventor Desiree L. Thompson

Desiree L. Thompson 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).

  • Devices for stretching polymer films
    Patent number: 7316558
    Abstract: Stretched polymeric films can be used in a variety of applications, including optical applications. The stretching conditions and shape of the stretching tracks in a stretching apparatus can determine or influence film properties. Methods and stretching apparatuses can include adjustable or zone-defined stretching regions.
    Type: Grant
    Filed: August 2, 2006
    Date of Patent: January 8, 2008
    Assignee: 3M Innovative Properties Company
    Inventors: William W. Merrill, Jeffery N. Jackson, Andrew T. Ruff, Desiree L. Thompson, John A. Wheatley, Jeffrey D. Amundson, Curtis A. Harvey
  • Apparatus for making transversely drawn films with substantially uniaxial character
    Patent number: 7153122
    Abstract: A process for stretching films is described. The process preferably stretches films in a uniaxial fashion. Preferably, optical films are stretched including multilayer optical films. Other aspects of the invention include a roll of stretched film and an apparatus for stretching films.
    Type: Grant

  • Devices for conveying, stretching, and taking-away polymer films
    Patent number: 7153123
    Abstract: Stretched polymeric films can be used in a variety of applications, including optical applications. The stretching conditions and shape of the stretching tracks in a stretching apparatus can determine or influence film properties. Take-away systems can be used to receive the film after stretching. The configuration of the take-away system can, in at least some instances, influence final film properties.
