Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
57 words
A esuperconductor composite comprising a rod of ductile normal material, the periphery of which having a plurality of grooves extending in a longitudinal direction along a helical path penetrating part-way towards the axis of the rod, each groove containing at least one superconducting filament extending the length of the groove, the mouths of the grooves being closed.
Claim 2
Dependent Claim
57 words
A esuperconductor composite comprising a rod of ductile normal material, the periphery of which having a plurality of grooves extending in a longitudinal direction along a helical path penetrating part-way towards the axis of the rod, each groove containing at least one superconducting filament extending the length of the groove, the mouths of the grooves being closed.
Claim 3
Dependent Claim
13 words
A superconductor composite as claimed in claim 1 wherein the rod is hollow.
Claim 4
Dependent Claim
50 words
A superconductor composite as claimed in claim 1 in which each superconductor filament is provided in a group of such filaments which are held together and embedded in a wire of normal material, and said wire is inserted in the corresponding groove in order to enter the superconductor filaments therein.
Claim 5
Dependent Claim
37 words
A superconductor composite as claimed in claim 1 wherein some at least of said grooves are provided with a corresponding reinforcing wire of a material having a greater specific strength than that of said ductile normal material.
Claim 6
Dependent Claim
30 words
A superconductor composite as claimed in claim 2 wherein said hollow contains a reinforcing wire of a material of a greater specific strength than that of said ductile normal material.
Claim 7
Dependent Claim
37 words
