Albert B. Macknick 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).

  • Corrosion protection system
    Patent number: 4990231
    Abstract: Methods of preventing corrosion in which current flows between the to-be-protected substrate and a distributed electrode whose electrochemically active surface is provided by an element which is composed of a conductive polymer and which is at least 500 microns thick. In one embodiment, the electrode is a flexible strip comprising a highly conductive core. e.g. of copper, and a conductive polymer element surrounding the core. In another embodiment, the electrode is a conductive polymer layer which conforms to the surface of the substrate but is separated from it by a layer of insulation.
    Type: Grant
    Filed: January 26, 1990
    Date of Patent: February 5, 1991
    Assignee: Raychem Corporation
    Inventors: Ray F. Stewart, Michael Masia, Albert B. Macknick
