Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
A conductor for an electric cable comprising: A. a central wire and a plurality of layers of helically applied wires surrounding said central wire, an innermost of said layers consisting of six wires and each additional layer consisting of a plurality of wires six in number greater than the number of wires in the directly underlying layer, B. the gage of individual wires in any layer being not less than the gage of any underlying wire, and C. said conductor being compacted to a diameter at least 8 percent less than the diameter of a concentric lay conductor of equal circular mil area.
Claim 2
Dependent Claim
103 words
A conductor for an electric cable comprising: A. a central wire and a plurality of layers of helically applied wires surrounding said central wire, an innermost of said layers consisting of six wires and each additional layer consisting of a plurality of wires six in number greater than the number of wires in the directly underlying layer, B. the gage of individual wires in any layer being not less than the gage of any underlying wire, and C. said conductor being compacted to a diameter at least 8 percent less than the diameter of a concentric lay conductor of equal circular mil area.
Claim 3
Dependent Claim
26 words
The cable of claim 1 wherein said central wire and all of said wires in said layers are round and of the same gage before compacting.
Claim 4
Dependent Claim
38 words
The cable of claim 1 comprising at least two of said layers of round wires of the same gage as said central wire and an outer of said layers of square wires of a larger gage, before compacting.
Claim 5
Dependent Claim
12 words
The cable of claim 1 wherein all of said wires comprise copper.
Claim 6
Dependent Claim
13 words
The cable of claim 4 wherein said layers alternate in direction of lay.
