Steven Warshawsky 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).

  • Patent number: 7651553
    Abstract: The present invention provides a ballast circuit and method for fabricating the same for multi-electrode corona discharge arrays. The circuit includes a conductive plastic material and at least one corona electrode protruding from the conductive plastic material. The distance between the plastic material and the corona electrode varies and controls the electrical resistance and determines the voltage breakdown of the circuit. Additionally, a particle collection surface may preferably be located within the conductive plastic material or preferably be separated from the material depending on the circuit design and configuration.

  • Publication number: 20070122320
    Abstract: The present invention relates to a Wet Electrostatic Precipitator Air (WEPA) Purifier and purification method capable of stand-alone operation as the principal air purification system, particularly in military applications. This system is intended to supply small military units within a temporary structure clean, threat-free fresh air for periods up to 12 months without maintenance. The WEPA Purifier is configured to remove and sterilize biological threat particles from an airflow, and further remove and sequester radioactive particulates, thus allowing them to be safely removed at normal maintenance periods. The WEPA Purifier includes a wet electrostatic precipitator filtration element in which particles are charged and collected by a capturing solution flowing over an attracting electrode collection plate. The water is returned by gravity to a reservoir where it is disinfected and captured particles retained in a small, low maintenance, regenerative liquid filter.
