  • Electrical machine with a superconducting rotor having an improved warm damper shield and method of making same
    Patent number: 4914328
    Abstract: An electrical machine with a superconducting rotor is constructed with a warm damper shield that uses a composite cylindrical assembly of a conductive core in a plurality of inner and outer support tubes. The conductive core is joined to axially adjacent end cylinders of high strength material by the use of mating grooves in the adjacent elements which permits them to be subjected to the forces resulting from the explosive welding of the inner and outer support tubes without damage thereto.
    Type: Grant

  • Warm damper for a superconducting rotor
    Patent number: 4465106
    Abstract: A warm damper for a superconducting rotor is described which uses a laminar assembly of a conductive tube and a plurality of support tubes. The conductive tube is soldered to axially adjacent support tubes and the resulting composite tube is explosively welded to two or more support tubes disposed adjacent to its radially inner and outer surfaces.

  • Radiant heat shield for a superconducting generator
    Patent number: 4432411
    Abstract: A radiant heat shield for use in a superconducting generator is described which is formed by brazing an inner and an outer tube together. The inner tube has a plurality of coolant channels machined in its outer cylindrical surface. The brazing operation consists of applying a brazing compound to the outer cylindrical surface of the inner tube prior to cold working the two tubes together, followed by a heating to a temperature in excess of the melting point of the brazing compound.
