Abstract
Abstract An improved ribbon cable comprising a plurality of insulated wires juxtaposed in fixed relationship to each other. An improved transposed cable in which each conductor of the cable of the invention is in the form of a continuous helix. An electromagnetic device having the ribbon cable of the invention as its magnetic windings, and methods and apparatus for manufacturing both the ribbon cable and the transposed cable of the invention.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
166 words
A ribbon cable compirisng: a plurality of elongated conductors extending the full length of the cable, each conductor having superimposed thereon an essentially continuous and concentric coat of flexible insulating material, said conductors each having an axis in a common plane, said axes being parallel, each of said conductors being side by side with the insulating coatings of adjacent conductors being contiguous, said conductors being bonded together, said conductor axes being angularly disposed to longitudinal axis of said cable, said conductors beind floded at the boundaries of said cable, said cable having two layers of conductors, said conductors defining a plurality of laterally flattened, juxtaposed helices wherein the width of said ribbon cable in the direction of said lateral flattening is essentially equal to the number of conductors in said plurality multiplied by the nominal outside diameter of said conductors divided by twice the cosine of the acute angle between said insulated conductors of said laterally flattened helices and the longitudinal axis of said ribbon cable.
Claim 2
Dependent Claim
166 words

Claim 3
Dependent Claim
12 words
The cable of claim 1 wherein said conductor layers are bonded together.
Claim 4
Dependent Claim
19 words
The cable of claim 1 wherein said conductors are chosen from the group consisting of aluminum and copper conductors.
Claim 5
Dependent Claim
16 words
The cable of claim 1 wherein said conductors are provided in a number greater than thirty-one.
Claim 6
Dependent Claim
24 words
The cable of claim 1 further comprising an essentially continuous and concentric coat of flexible bonding material superimposed on said coat of insulating material.
Claim 7
Dependent Claim
31 words
The cable of claim 1 further comprising a bonding material in the interstices between said conductors, said bonding material generally defining the exterior configuration of said ribbon cable with said conductors.
Claim 8
Dependent Claim
19 words
The cable of claim 3 or 4 wherein said bonding material is the same material as said insulating material.
Claim 9
Dependent Claim
18 words
The cable of claim 3 or 4 wherein said bonding material is softenable by the application of heat.
Claim 10
Dependent Claim
18 words
The cable of claim 3 or 4 wherein said bonding material is softenable by the application of solvent.
