Bradley Keith Coltrain 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).

  • Patent number: 5853819
    Abstract: Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer and an electrically-conductive layer produced by coating a layer comprised of a metallo-organic compound and a film-forming binder and subjecting such layer to glow discharge treatment to render it electrically conductive. Use of a metallo-organic compound in combination with a glow discharge treatment provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.
    Type: Grant
    Filed: October 24, 1996
    Date of Patent: December 29, 1998
    Assignee: Eastman Kodak Company
    Inventors: Mark Lelental, Bradley Keith Coltrain, David Appler Glocker, Dennis R. Freeman, Jeremy Matthew Grace
  • Patent number: 5691123
    Abstract: Elements having a support with lubricant on both sides can be treated to remove substantially all of the lubricant from one side only. Various chemical, mechanical and electrical treatments are contemplated, but glow discharge treatment is particularly useful. Photographic film supports having one or more layers applied thereto can be treated in this manner before or after annealing so that lubricant present on the treated side does not reduce adhesion of later applied silver halide emulsion layers.
