Steve L. Larson 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).

  • Neutral, high visible, durable low-E glass coating system, insulating glass units made therefrom, and methods of making same
    Patent number: 6059909
    Abstract: A sputter-coated layer system on a glass substrate particularly useful in insulating glass (IG) units, enables normal emissivity values (E.sub.n) of 0.06 or less, good durability and neutral color. The layer system includes an undercoat of a transparent dielectric having an index of refraction between 2.5-2.6 at a wavelength of 550 nanometers, two layers of Si.sub.3 N.sub.4, and two layers of nichrome sandwiching a layer of silver to achieve its unique low-E, neutral color, non-mirrorlike solar management properties. An optional overcoat of a transparent dielectric material having an index of refraction of 2 at a wavelength of 550 nanometers may be provided.
    Type: Grant
    Filed: February 25, 1998
    Date of Patent: May 9, 2000
    Assignee: Guardian Industries Corp.
