  • Reduced VOC coatings using chemically modified hyperbranched polymers
    Patent number: 7851539
    Abstract: Reduced VOC coatings are provided that include small amounts of modified hyperbranched polymers added and reduced solvents to reduce VOC levels by as much as 30% and more. The reduced VOC coatings have substantially improved flow and performance characteristics over comparable commercially available reduced VOC coatings.
    Type: Grant
    Filed: September 28, 2006
    Date of Patent: December 14, 2010
    Assignee: The United States of America as represented by the Administrator of the United States Environmental Protection Agency
    Inventors: Carlos M. Nunez, Geddes H. Ramsey, Pamela M. Barfield, Larry G. Jones, Anthony L. Andrady

  • Low temperature destruction of toxics in pollutant air streams
    Patent number: 5476640
    Abstract: Low temperature apparatus for the destruction of low volume time varying organic air toxins in air streams utilizing non-catalytic glass beads in parallel conduits heated by hot gas flow around the conduits and flowing the air stream through the conduits and controlling the hot gas flow in response to toxin levels in the air stream.
    Type: Grant
    Filed: August 25, 1994
    Date of Patent: December 19, 1995
    Assignee: The United States of America as represented by the Administrator of the U.S. Environmental Protection Agency
    Inventors: James H. Abbott, Dennis C. Drehmel, Geddes H. Ramsey
  • Corona destruction of volatile organic compounds and toxics
    Patent number: 5236672
    Abstract: Apparatus and method for controlling volatile organic compounds and air toxics in a contaminated fluid flow through use of an excited species flow generated and introduced into the contaminated fluid flow to convert the contaminants into non-toxic compounds. Tungsten electrodes and an alternating current are used in the excited species generator.
