Patents by Inventor Paul J. Di Pietro

Paul J. Di Pietro 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).

  • Laminated superconducting ceramic tape
    Patent number: 6230033
    Abstract: A superconducting ceramic includes a laminate and a superconducting ceramic tape joined to the laminate. The laminate and superconductor tape are joined such that the tape is under a compressive stress. The compressive stress is of a greater amount than compressive stress which results from differences in thermal expansion of the tape and the laminate. The greater compressive stress can be achieved by putting the laminate under a greater tension than the superconducting ceramic tape during joining of the superconducting ceramic tape to the laminate.
    Type: Grant
    Filed: September 23, 1999
    Date of Patent: May 8, 2001
    Assignee: American Superconductor Corporation
    Inventors: John D. Scudiere, David M. Buczek, Gregory L. Snitchler, Paul J. Di Pietro
