Roger Wheatley 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).

  • Hybrid high field superconducting assembly and fabrication method
    Patent number: 6020803
    Abstract: In a high field superconducting magnet device, e.g., for NMR, a conventional low temperature superconducting solenoid type magnet is combined with an inserted superconducting magnet, which is fabricated from high temperature superconducting materials having very high critical currents. Both magnets operate with stability at the same low temperature in persistent modes after operating conditions are achieved. The flux field and superconducting currents in the inserted superconducting magnet are generated by flux trapping when the field of the low temperature superconducting solenoid type magnet is reduced. The field of the hybrid magnet assembly is the resultant of the respective fields of the two magnets.
    Type: Grant

    Date of Patent: February 1, 2000
    Assignee: Intermagnetics General Corporation
