James S. Gamble 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).

  • Detector for dry deposition of atmospheric contaminants having a coating capable of retaining contaminants
    Patent number: 4932254
    Abstract: A detector for dry deposition of atmospheric contaminants comprised of a surrogate surface upon which the contaminants are deposited from the atmosphere; an airfoil-type surface circumferentially surrounding the surrogate surface and providing a laminar or transition boundary layer flow over the surrogate surface; and a post supporting the surrogate surface and airfoil-type surface in the atmosphere. With the detector, the flux of a contaminant in the atmosphere can then be determined from the area of the surrogate surface and the mass of contaminants collected therefrom over a given time.
    Type: Grant
    Filed: June 17, 1988
    Date of Patent: June 12, 1990
    Assignee: Carnegie-Mellon University
    Inventors: Cliff I. Davidson, Gregory J. McRae, James S. Gamble
