Patents by Inventor John F. Enos

John F. Enos 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).

  • Method for evolution of oxygen with ternary electrocatalysts containing valve metals
    Patent number: 4707229
    Abstract: A gas generating apparatus and method is described which utilizes a novel catalytic oxygen evolving electrode for such electrochemical systems as electrolysis cells and oxygen concentration cells. The electrochemical cells include a catalytic cathode and an improved catalytic anode positioned on opposite sides of, and in electrical contact with, a cation exchange membrane. A source of direct current potential between the cathode and the anode and means for removing gas from at least one of the electrodes are provided. The improved catalytic anode is a ternary platinum group reduced metal oxide alone or in combination with platinum group metals and/or platinum group metal oxides or mixtures of the foregoing having at least one valve metal component such as titanium, hafnium, zirconium, niobium, tantalum and tungsten.
    Type: Grant
    Filed: December 22, 1983
    Date of Patent: November 17, 1987
    Assignee: United Technologies Corporation
    Inventors: Russell M. Dempsey, Anthony R. Fragala, Anthony B. LaConti, John F. Enos
