Abstract
Abstract A conductor system for superconducting electrical cables, wherein a tubular member supports on its inner surface superconducting conductor strands disposed at an angle to the axis of the support member; the strands being adherent to the support member at spaced points along the length of the strand and the strand portions between said points being nonadherent to the support member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
51 words
A conductor system for superconducting cables comprising a tubular synthetic resin member for carrying a liquid coolant therethrough, elongated superconductive members mounted on the inner surface of said tubular member for contact with said coolant, said superconductive members being disposed at an angle to the longitudinal axis of said tubular member.
Claim 2
Dependent Claim
51 words
A conductor system for superconducting cables comprising a tubular synthetic resin member for carrying a liquid coolant therethrough, elongated superconductive members mounted on the inner surface of said tubular member for contact with said coolant, said superconductive members being disposed at an angle to the longitudinal axis of said tubular member.
Claim 3
Dependent Claim
16 words
A system as in claim 1 wherein said tubular member has openings in the wall thereof.
Claim 4
Dependent Claim
15 words
A system as in claim 2 wherein said openings are arranged to form a meshwork.
Claim 5
Dependent Claim
26 words
A system as in claim 1 wherein said synthetic resin is a copolymer of polyethylene and monomers to render said resin adherent to said superconductive members.
Claim 6
Dependent Claim
16 words
A system as in claim 1, wherein said superconductive members have a predetermined spacing pattern therebetween.
Claim 7
Dependent Claim
28 words
A system as in claim 1, wherein said superconductive members are adherent at spaced intervals along the length thereof to opposed inner surface portions of said tubular member.
Claim 8
Dependent Claim
24 words
A system as in claim 1 wherein said superconductive members have a profiled cross section for mechanically interconnecting said members with said tubular member.
Claim 9
Dependent Claim
39 words
A system as in claim 1 wherein said superconductive members comprise a thin layer of superconductive metal and a layer of synthetic resin, said layer of synthetic resin being adherent To said superconductive metal and to said tubular member.
Claim 10
Dependent Claim
53 words
A system as in claim 1 and further including a tape of material wound helically with spaced turns between said superconductive members and said tubular member, the opposed portions of said superconductive members and said tubular member in the spaces between turns of said tape material being in adherent relation to each other.
