    Abstract: A composite superconductor formed from a high specific heat ceramic such as gadolinium oxide or gadolinium-aluminum oxide and a conventional metal conductor such as copper or aluminum which are insolubly mixed together to provide adiabatic stability in a superconducting mode of operation. The addition of a few percent of insoluble gadolinium-aluminum oxide powder or gadolinium oxide powder to copper, increases the measured specific heat of the composite by one to two orders of magnitude below the 5.degree. K. level while maintaining the high thermal and electrical conductivity of the conventional metal conductor.

    Abstract: An electrical conductor which is particularly useful in the transmission of three-phase current, and which comprises an inner conductor made up of a plurality of individual super-conducting conductors arranged in several layers and an outer conductor also made up of a plurality of individual superconducting conductors, surrounding the inner conductor concentrically and spaced therefrom, in which at least the individual conductors of the inner conductor are of an elliptical cross section with their major axes perpendicular to radials of the inner conductor to result in a conductor having a-c losses which are relatively small.

    Abstract: A hybrid superconducting material in which superconducting strands, at least partially surrounded by a layer of low resistance normally conducting material, are embedded in a matrix of high resistance normally conducting material. In a specific embodiment, the superconducting strands consist essentially of niobium titanium, individually surrounded by a thin sleeve of copper, and embedded in a matrix of cupro-nickel. The composite is extruded at elevated temperatures and pressure. The wire so formed may be used for electromagnet coils designed to function in a cryogenic system.

    Abstract: 1219621 Super-conductors SIEMENS AG 5 June 1968 [24 June 1967] 26854/68 Headings H1A and A4D A tape form conductor comprises a superconductor current carrier coated with a normal metal and soldered between two tapes of normal metal, the adjacent faces of the tapes being provided with opposed longitudinal grooves to receive the current carrier. As shown, Fig. 1, a plurality of super-conductor wires 1 having coatings of a normal metal 2 are located in grooves in the faces of two tapes 3, 4 of normal metal secured by solder 5. The tapes may be of copper and produced by rolling to form the grooves, annealing, brushing to remove any oxide surface layers, and coating at least the grooved faces with solder. The super-conductor wire is coated with copper the surface of which is cleaned by etching and then covered with a layer of solder by dipping. The prepared wires are inserted into the grooves between the tapes which are then passed through a pair of heated jaws to solder the components together. In a first modification, each of the conductors comprises a plurality of strands of super-conductor material, having individual coatings of normal metal twisted together. In a second modification the conductors at the edges of the tape are replaced by wires of high strength metal, for example steel coated with copper. The super-conductor material may be an alloy of niobium and zirconium (25 to 50 wt per cent Zr) or of niobium and titanium (40 to 70 wt per cent Ti) and may be coated with gold or silver instead of copper. The solder has a low melting point and may be tin, indium, lead, an alloy of tin and silver (3À5 or 6 wt per cent Ag), an alloy of tin and indium, or an alloy of tin and lead (48 wt per cent Pb).
