Steven F. Fulton 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).

  • Hot melt ink transparency
    Patent number: 4877676
    Abstract: In the particular embodiments of the invention described in the specification, a transparency includes a transparent substrate made of a polyester material, an ink pattern disposed on one surface of the transparent sheet in the form of three-dimensional ink spots having curved surfaces and a transparent layer convering the ink spots which has an index of refraction approximately the same as that of the ink spots. The transparent layer is applied to the substrate and the ink spots in the form of a liquid coating which wets the surfaces of the substrate and ink spots and spreads over them to produce a transparent layer having a maximum deviation of about 20 degrees from a plane parallel to the substrate.
    Type: Grant

  • Method for preparing a hot melt ink transparency
    Patent number: 4801473
    Abstract: A transparency includes a transparent substrate such as a polyester material, an ink pattern disposed on one surface of the transparent sheet in the form of three-dimensional ink spots having curved surfaces and a transparent layer covering the ink spots which has an index of refraction approximately the same as that of the ink spots. The transparent layer is applied to the substrate and the ink spots in the form of a liquid coating which wets the surfaces of the substrate and ink spots and spreads over them to produce a transparent layer having a maximum deviation of about 20 degrees from a plane parallel to the substrate.
