Patents by Inventor Lyle Dwight Nelsen

Lyle Dwight Nelsen 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: 8717733
    Abstract: Self-balancing, corona discharge for the stable production of electrically balanced and ultra-clean ionized gas streams is disclosed. This result is achieved by promoting the electronic conversion of free electrons into negative ions without adding oxygen or another electronegative gas to the gas stream. The invention may be used with electronegative and/or electropositive or noble gas streams and may include the use of a closed loop corona discharge control system.
    Type: Grant
    Filed: December 30, 2012
    Date of Patent: May 6, 2014
    Assignee: Illinois Tool Works Inc.
    Inventors: Peter Gefter, Leslie W. Partridge, Lyle Dwight Nelsen
  • Patent number: 8460433
    Abstract: Clean corona gas ionization by separating contaminant byproducts from corona generated ions includes establishing a non-ionized gas stream having a pressure and flowing in a downstream direction, establishing a plasma region of ions and contaminant byproducts in which the pressure is sufficiently lower than the pressure of the non-ionized gas stream to prevent at least a substantial portion of the byproducts from migrating into the non-ionized gas stream, and applying an electric field to the plasma region sufficient to induce at least a substantial portion of the ions to migrate into the non-ionized gas stream.
