  • Cylindrical composite superconductor bearing
    Patent number: 5130588
    Abstract: A cylindrical superconductor bearing is made of Type II ceramic superconductor, dispersed in an acrylic thermoplastic carrier in a ratio between 1:1 and 3:1 by volume. The cylindrical superconductor bearing is particularly useful as a magnetic journal bearing.
    Type: Grant
    Filed: February 6, 1991
    Date of Patent: July 14, 1992
    Assignee: Allied-Signal Inc.
    Inventors: Timothy R. Armstrong, John R. Esopa, Thomas K. Rigney, II, Marshall P. Saville
  • Composite superconductor disc bearing
    Patent number: 5126611
    Abstract: A Type II ceramic superconductor is dispersed in an acrylic thermoplastic carrier in a ratio between 1:1 and 3:1. Resulting is a readily formable, thermosetting superconductor composite. The superconductor composite is particularly useful as a magnetic bearing or for fabricating devices to contain magnetic flux, because of its "flux pinning" effect.
