Abstract
Abstract An improved type of ribbon-shaped conductor made up of a plurality of individual conductors of normal conducting metal arranged side-by-side and welded together, some of which conductors have embedded superconductors wherein the individual conductors not containing superconductors are arranged so as to have at least portions thereof of a different thickness than the individual conductors containing superconductors whereby when the overall ribbon-shaped conductor is installed with one layer of this conductor over another, cooling ducts are formed which result in improved cooling of the superconductors.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
75 words
In a ribbon-shaped conductor which comprises a plurality of individual conductors made of electrically normal conducting metals which are arranged side-by-side and welded together, with some but not all of the individual conductors having embedded therein superconductors wherein the improvement comprises forming at least some of the individual conductors not containing superconductors so that at least portions of said individual conductors are of a different thickness than that of the individual conductors containing said superconductors.
Claim 2
Dependent Claim
75 words
In a ribbon-shaped conductor which comprises a plurality of individual conductors made of electrically normal conducting metals which are arranged side-by-side and welded together, with some but not all of the individual conductors having embedded therein superconductors wherein the improvement comprises forming at least some of the individual conductors not containing superconductors so that at least portions of said individual conductors are of a different thickness than that of the individual conductors containing said superconductors.
Claim 3
Dependent Claim
26 words
The invention according to claim 1 wherein at least some of said individual conductors which do not have superconductors embedded therein have spacer elements placed thereon.
Claim 4
Dependent Claim
13 words
The invention according to claim 2 wherein said spacer elements are electrically conductive.
Claim 5
Dependent Claim
29 words
The invention according to claim 3 wherein the width of said spacer element is less than the width of the individual conductor on which said spacer elements are placed.
Claim 6
Dependent Claim
16 words
The invention according to claim 1 wherein said spacer elements are of an electrically insulating material.
Claim 7
Dependent Claim
44 words
The invention according to claim 1 wherein said individual conductors not having superconductors embedded therein, have at least a strip shaped portion extending in the longitudinal direction which is of a thickness different than the thickness of said individual conductors having superconductors embedded therein.
Claim 8
Dependent Claim
48 words
The invention according to claim 6 wherein said individual conductors not having superconductors therein are thinner than said individual conductors having superconductors embedded therein and wherein said individual conducts having superconductors embedded therein are bevelled at the point where they meet said individual conductors not having superconductors therein.
Claim 9
Dependent Claim
48 words
The invention according to claim 6 wherein said individual conductors not having superconductors therein are thicker than said individual conductors having superconductors embedded therein and wherein said individual conductors not having superconductors therein are bevelLed at the point where they meet said individual conductors having superconductors embedded therein.
Claim 10
Dependent Claim
19 words
The invention according to claim 1 wherein said individual conductors not having superconductors embedded therein are provided with cutouts.
Claim 11
Dependent Claim
49 words
The invention according to claim 1 wherein each individual conductor not having superconductors embedded therein comprises a plurality of elongated conductors extending one-behind the other in said ribbon shaped conductor, the end faces of adjacent elongated conductors spaced from each other, whereby slots are formed through said ribbon-shaped conductors.
Claim 12
Dependent Claim
31 words
The invention according to claim 1 wherein the width of said individual conductors not having superconductors embedded therein is less than the width of the individual conductors having superconductors embedded therein.
