    Inventors: Neil G. Fiddes, Christopher G. King, Anthony Mantone, Frank D. Shaffer
  • Patent number: 5379019
    Abstract: An apparatus for manufacturing embossed foil for use in controlling the flow of the molten metal tin plating provided in forming laminated tape for use in superconducting magnets utilizing meshing knurling rollers with truncated paramydical elements arranged to provide and embossed pattern for uniform and controlled flow of the tin.
    Type: Grant
    Filed: October 12, 1993
    Date of Patent: January 3, 1995
    Assignee: General Electric Company
    Inventors: Neil G. Fiddes, Christopher G. King, Gerhard S. Kobus, Anthony Mantone, Frank D. Shaffer
  • Patent number: 5332867
    Abstract: A detachable seal assembly for a pressurized constant process oven through which a flat filament is passed and which seals the oven against the environment surrounding the oven including a resilient aperture formed by opposed flaps which extend from a transverse portion in the direction of movement of the filament to sandwich the filament. Compression is provided to the seal assembly such that the friction of filament movement tends to stretch the flaps to seal the resilient aperture about the filament. The seal assembly includes a clamp to enable ready replacement to minimize process down time during replacement.
    Type: Grant
    Filed: August 3, 1992
    Date of Patent: July 26, 1994
    Assignee: General Electric Company
    Inventors: Frank D. Shaffer, Malvin L. Dennis
  • Patent number: 5299728
    Abstract: Apparatus and method for forming long lengths of laminated superconducting tape by passing three foils over idler pulleys, through a solder bath and between pinch rollers having a portion which extend above the solder bath to enable cleaning of the pinch rollers during the formation of the superconducting tape with means to adjust the pressure applied by the pinch rollers, and to adjust the laminated tape takeup tension independently from the foil process tension.
