  • Composite lead for conducting an electrical current between 75-80K and 4.5K temperatures
    Patent number: 5376755
    Abstract: A composite lead is provided which electrically links and conducts a current between about 75-80K. and liquid helium temperature of about 4.5K. The composite lead may be employed singly or in multiples concurrently to provide conduction of electrical current from normal conductors and semi-conductors at room temperature to superconductors operating at 4.5K. In addition, a variety of organizationl arrangements and assemblies are provided by which the mechanical strength and electrical reliability of the composite lead is maintained.

  • Method for making an electrically conductive contact for joining high T.sub .
    Patent number: 5296459
    Abstract: The present invention provides a methodology for forming an electrically conductive contact on the external surface of superconductive materials. The methodology is employed using any Noble metal to form the conductive contact; and is used with any superconductive material conventionally known. The resulting conductive contact provides a low electrical resistance and firm point of electrical junction for the superconductor with any conductive material in any electrical circuit or use.
