Leonard B. Todd 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).

  • Reactor design to reduce particle deposition during process abatement
    Patent number: 7985379
    Abstract: The present invention relates to systems and methods for controlled combustion and decomposition of gaseous pollutants while reducing deposition of unwanted reaction products from within the treatment systems. The systems include a novel thermal reaction chamber design having stacked reticulated ceramic rings through which fluid, e.g., gases, may be directed to form a boundary layer along the interior wall of the thermal reaction chamber, thereby reducing particulate matter buildup thereon. The systems further include the introduction of fluids from the center pilot jet to alter the aerodynamics of the interior of the thermal reaction chamber.
    Type: Grant
    Filed: August 14, 2007
    Date of Patent: July 26, 2011
    Assignee: Applied Materials, Inc.
    Inventors: Ho-Man Rodney Chiu, Daniel O. Clark, Shaun W. Crawford, Jay J. Jung, Leonard B. Todd, Robbert Vermeulen
