Abstract
Abstract A superconductor comprises two superconducting wires butt-jointed, a superconducting doubling wire electrically and mechanically connecting the superconducting wires, and a stabilizer attached to the superconductors and the doubling wire to extend therealong, the superconductors, the doubling wire and the stabilizer together forming a superconductor of a constant cross-sectional area. A manufacturing process is also disclosed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
54 words
A superconductor joint comprising two superconducting wires axially aligned and butt-jointed, a superconducting doubling wire extending along and electrically connecting the superconducting wires, and a stabilizer attached to said superconductors and said doubling wire to extend therealong, said superconductors, said doubling wire and said stabilizer together forming a superconductor of a constant cross-sectional area.
Claim 2
Dependent Claim
54 words
A superconductor joint comprising two superconducting wires axially aligned and butt-jointed, a superconducting doubling wire extending along and electrically connecting the superconducting wires, and a stabilizer attached to said superconductors and said doubling wire to extend therealong, said superconductors, said doubling wire and said stabilizer together forming a superconductor of a constant cross-sectional area.
Claim 3
Independent Claim
70 words
A method for manufacturing a superconductor joint comprising the steps of: butt joining adjacent ends of superconducting wires; surrounding the butt-jointed superconducting wires with extruded stabilizer material; removing a portion of said stabilizer material to expose the butt-jointed end regions of said superconducting wires; and bonding a superconducting doubling wire to the exposed surface of said superconducting wires to electrically and mechanically connect said two superconducting wires across said butt-joint.
