Permanent magnet design for high-speed superconducting bearings

Patent Hull, John R [5519 S. Bruner, Hinsdale, IL 60521]; Uherka, Kenneth L [830 Ironwood, Frankfort, IL 60423]; Abdoud, Robert G [13 Country Oaks La., Barrington Hills, IL 60010]

A high temperature superconducting bearing including a permanent magnet rotor levitated by a high temperature superconducting structure. The rotor preferably includes one or more concentric permanent magnet rings coupled to permanent magnet ring structures having substantially triangular and quadrangular cross-sections. Both alternating and single direction polarity magnet structures can be used in the bearing.

Synthesis of high T.sub.C superconducting coatings and patterns by melt writing and oxidation of metallic precursor alloys

Patent Gao, Wei [Somerville, MA]; Vander Sande, John B [Newbury, MA]

A method is provided for fabrication of superconducting oxides and superconducting oxide composites and for joining superconductors to other materials. A coating of a molten alloy containing the metallic elements of the oxide is applied to a substrate surface and oxidized to form the superconducting oxide. A material can be contacted to the molten alloy which is subsequently oxidized joining the material to the resulting superconducting oxide coating. Substrates of varied composition and shape can be coated or joined by this method.
