Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
83 words
In an electromechanical cable, a composite strain member comprising: a plurality of fibers having high tensile strength and slick surfaces disposed in adjacent parallel relationship to form a bundle; and a jacket of plastic material enclosing said bundle; the cross-sectional configuration of said composite member being easily deformable, and said jacket serving to confine said fibers in a predetermined lateral position while said fibers may slide longitudinally relative to each other and within said jacket as required by mechanical movements of the cable.
Claim 2
Dependent Claim
83 words
In an electromechanical cable, a composite strain member comprising: a plurality of fibers having high tensile strength and slick surfaces disposed in adjacent parallel relationship to form a bundle; and a jacket of plastic material enclosing said bundle; the cross-sectional configuration of said composite member being easily deformable, and said jacket serving to confine said fibers in a predetermined lateral position while said fibers may slide longitudinally relative to each other and within said jacket as required by mechanical movements of the cable.
Claim 3
Dependent Claim
51 words
In an electromechanical cable, a composite strain member comprising: a plurality of fibers of high tensile strength disposed in side-by-side relationship to form a bundle; lubricating means on the surface of said bundle; and a plastic jacket enclosing said bundle and lubricating means; said bundle being longitudinally slidable within said jacket.
Claim 4
Dependent Claim
51 words
In an electromechanical cable, a composite strain member comprising: a plurality of fibers of high tensile strength disposed in side-by-side relationship to form a bundle; lubricating means on the surface of said bundle; and a plastic jacket enclosing said bundle and lubricating means; said bundle being longitudinally slidable within said jacket.
Claim 5
Dependent Claim
17 words
A strain member as in claim 1 which is deformed to have a substantially rectangular cross-sectional configuration.
Claim 6
Dependent Claim
14 words
A strain member as in claim 1 wherein said fibers are made of aramid.
Claim 7
Dependent Claim
61 words
In an electromechanical cable, a plurality of strain members arranged in a circumferential layer, each of said strain members including a bundle of yarns of high tensile strength and a plastic jacket surrounding said bundle, each of said bundle of yarns being longitudinally slidable within the corresponding jacket, the plastic jackets of adjacent ones of said strain members being bonded together.
Claim 8
Dependent Claim
61 words
In an electromechanical cable, a plurality of strain members arranged in a circumferential layer, each of said strain members including a bundle of yarns of high tensile strength and a plastic jacket surrounding said bundle, each of said bundle of yarns being longitudinally slidable within the corresponding jacket, the plastic jackets of adjacent ones of said strain members being bonded together.
