Patents by Inventor John H. Huys

John H. Huys 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).

  • Welding electrode
    Patent number: 4861961
    Abstract: Electrodes for use in electric resistance welding and a method of making such electrodes are disclosed. The electrodes are each shaped to define a tip surface for contact with a workpiece during welding. In one embodiment, each electrode comprises an electrode body of copper and a layer of titanium carbide on the body defining said tip surface. The titanium carbide layer is fused to the electrode body by a spark-fusion technique and forms a unitary electrode with the body. This form of electrode has been found advantageous in terms of minimizing "pick-up" of workpiece material during welding, and distortion of the electrode.
    Type: Grant
