Patents by Inventor Kenneth L. Uherka

Kenneth L. Uherka 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).

  • Low-loss, high-speed, high-T.sub.c superconducting bearings
    Patent number: 5640887
    Abstract: A flywheel energy storage device including an iron structure disposed for rotation adjacent a stationary superconductor material structure and a stationary permanent magnet. The stationary permanent magnet levitates the iron structure while the superconductor structure can stabilize the rotating iron structure.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: June 24, 1997
    Assignee: University of Chicago
    Inventors: John R. Hull, Thomas M. Mulcahy, Kenneth L. Uherka
  • Permanent magnet design for high-speed superconducting bearings
    Patent number: 5554583
    Abstract: A high temperature superconducting bearing including a permanent magnet rotor levitated by a high temperature superconducting structure. The rotor preferably includes one or more concentric permanent magnet rings coupled to permanent magnet ring structures having substantially triangular and quadrangular cross-sections. Both alternating and single direction polarity magnet structures can be used in the bearing.
    Type: Grant

  • Low-loss, high-speed, high-T.sub.C superconducting bearings
    Patent number: 5540116
    Abstract: A flywheel energy storage device including an iron structure disposed for rotation adjacent a stationary superconductor material structure and a stationary permanent magnet. The stationary permanent magnet levitates the iron structure while the superconductor structure can stabilize and levitate the rotating iron structure.
