Abstract
Abstract A method for producing a super-conductive coil and a coil produced in accordance with the method, wherein the coil is formed of a coil conductor containing a carrier consisting of a stabilizing material and a U-shaped steel sheath. In the carrier, a main duct is arranged in which at least one super-conductor wire or one super-conductor cable is embedded by means of a joining material. The super-conductor wire or the super-conductor cable is introduced into the main duct. Thereafter, the carrier is formed into the form of a coil and then the main duct with the super-conductor wire or the super-conductor cable is filled with the thermally and electrically conductive joining material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
80 words
A method for producing a super-conductive coil to be formed as a coil conductor containing a carrier which essentially consists of a stabilizing material and in which a main duct is provided in which at least one super-conductor cable is to be embedded in a joining material, comprising: loosely inserting the super-conductor cable into the main duct; shaping the carrier into the shape of a coil; and completely filling the main duct having the super-conductor cable with the joining material.
Claim 2
Independent Claim
80 words
A method for producing a super-conductive coil to be formed as a coil conductor containing a carrier which essentially consists of a stabilizing material and in which a main duct is provided in which at least one super-conductor cable is to be embedded in a joining material, comprising: loosely inserting the super-conductor cable into the main duct; shaping the carrier into the shape of a coil; and completely filling the main duct having the super-conductor cable with the joining material.
Claim 3
Independent Claim
96 words
A method for producing a super-conductive coil to be formed of a coil conductor containing a carrier which essentially consists of a stabilizing material and in which a main duct is provided wherein at least one super-conductor cable is to be embedded in a joining material, comprising: loosely inserting a cable which can be made super-conductive by means of reaction annealing into the main duct; shaping the carrier into the shape of a coil; reaction annealing the cable into a super-conductive cable; and thereafter filling the main duct having the super-conductor cable with the joining material.
Claim 4
Independent Claim
96 words
A method for producing a super-conductive coil to be formed of a coil conductor containing a carrier which essentially consists of a stabilizing material and in which a main duct is provided wherein at least one super-conductor cable is to be embedded in a joining material, comprising: loosely inserting a cable which can be made super-conductive by means of reaction annealing into the main duct; shaping the carrier into the shape of a coil; reaction annealing the cable into a super-conductive cable; and thereafter filling the main duct having the super-conductor cable with the joining material.
Claim 5
Independent Claim
28 words
A method according to claims 1 or 2, wherein said filling step comprises: forcing the joining material into the main duct under the action of pressure and/or suction.
Claim 6
Independent Claim
44 words
A method according to claims 1 or 2, wherein the joining material is placed into the main duct at a temperature of the joining material and of the stabilizing material forming the main duct, which is above the melting point of the joining material.
Claim 7
Independent Claim
24 words
A method according to claims 1 or 2, wherein the joining material is filled into the main duct through at least one filling channel.
