Nelson William Sorbo 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).

  • NO.sub.x reduction method in corona discharge pollutant destruction apparatus
    Patent number: 6136158
    Abstract: Providing triatomic nitrogen (N.sub.3) as a relaxation species to an exhaust gas that includes nitrogen oxide compounds (NO.sub.x) increases the rate of reducing NO.sub.x in a corona discharge apparatus.
    Type: Grant
    Filed: August 19, 1996
    Date of Patent: October 24, 2000
    Assignee: Raytheon Company
    Inventors: John H. S. Wang, Nelson William Sorbo, Weldon S. Williamson, Edward J. Palen
  • Multi-electrode corona discharge pollutant destruction apparatus
    Patent number: 5927069
    Abstract: A corona discharge pollutant destruction reactor employs two or more electrodes to enhance the effective corona discharge treatment volume by distributing a varying electric field pattern over the reactor's interior chamber. Appropriate delay circuitry allows the inner electrodes to be driven out of phase with each other by a sinusoidal voltage waveform, or corona producing voltage pulses to be cyclically supplied to the inner electrodes in sequence, preferably without overlapping the pulses.
    Type: Grant
    Filed: December 19, 1997
    Date of Patent: July 27, 1999
    Assignee: Raytheon Company
    Inventors: John H. S. Wang, Weldon S. Williamson, Nelson William Sorbo, Franklin A. Dolezal
  • Indoor air pollutant destruction apparatus and method using corona discharge
    Patent number: 5827407
    Abstract: An indoor air pollutant destruction apparatus destroys pollutants by a corona discharge that is generated by a rapidly oscillating electric field. Free electrons generated by the corona discharge produces ozone (O.sub.3), which effectively destroys volatile organic compounds (VOCs) and biological forms such as bacteria, fungi, viruses and spores. Fine particulate materials such as smoke and dust are charged by the corona discharge, and when they pass through the rapidly oscillating electric field, they coagulate to form larger particles which are then filtered out.
    Type: Grant
    Filed: August 19, 1996
    Date of Patent: October 27, 1998
    Assignee: Raytheon Company
    Inventors: John H. S. Wang, Weldon S. Williamson, Nelson William Sorbo
  • Fuel injection system and method for treatment of NO.sub.x in a corona discharge pollutant destruction apparatus
    Patent number: 5807466
    Abstract: In a gaseous pollutant destruction apparatus employing a corona discharge reactor for reducing nitrogen oxide compounds (NO.sub.x), a fuel injection system provides a precisely controlled small quantity of hydrocarbon fuel to the corona discharge reactor to facilitate the destruction of NO.sub.x.
