Abstract
Abstract A method of manufacturing a superconductor composite comprising taking a rod of a ductile normal material of which the periphery is provided with a plurality of longitudinally-extending grooves penetrating part-way towards the longitudinal axis of the rod, locating within at least one of said grooves at least one superconductor filament extending along the length of said groove, and closing the mouths of said grooves, and a composite manufactured by this method.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
A method of manufacturing a superconductor composite comprising taking a rod of a ductile normal material of which the periphery is provided with a plurality of longitudinallyextending helical grooves penetrating part-way towards the longitudinal axis of the rod, locating within each of said grooves at least one superconductor filament extending along the length of said groove, inserting the rod and associated filaments in a tube of a ductile normal material, and elongating the resulting assembly in order to consolidate the assembly.
Claim 2
Independent Claim
81 words
A method of manufacturing a superconductor composite comprising taking a rod of a ductile normal material of which the periphery is provided with a plurality of longitudinallyextending helical grooves penetrating part-way towards the longitudinal axis of the rod, locating within each of said grooves at least one superconductor filament extending along the length of said groove, inserting the rod and associated filaments in a tube of a ductile normal material, and elongating the resulting assembly in order to consolidate the assembly.
Claim 3
Independent Claim
47 words
A method according to claims 1 wherein 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 4
Dependent Claim
35 words
A method according to claim 1 wherein at least some 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 5
Dependent Claim
31 words
A method according to claim 1 wherein said rod is hollow and contains a reinforcing wire of a material having a greater specific strength than that of said ductile normal material.
Claim 6
Dependent Claim
35 words
A method according to claim 3 wherein said material having a greater specific strength than that of said ductile normal material is selected from the group consisting of copper-beryllium alloys, stainless steel, cupro-nickel and titanium.
