Abstract
Abstract A high tensile strength transmission cable having a plurality of main compacted strands. The strands surround, and are adjacent to, an uncompacted and moveable core which may form or contain one or more transmission elements. A method for making such a high strength transmission cable includes the steps of compacting the cable formed by a plurality of pre-compacted strands wound around a hard core wire, opening the strands to replace the hard core wire with a soft core containing transmission elements, and then closing the strands.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
56 words
A composite high tensile strength towing cable including: an outer cable structure formed of a plurality of unitary strands, said strands being compacted into one another such that the cross-sectional shape of said strands is deformed from an initial circular shape to a final non-circular shape; and a central fragile non-deformed optical fiber signal transmission element.
Claim 2
Dependent Claim
56 words
A composite high tensile strength towing cable including: an outer cable structure formed of a plurality of unitary strands, said strands being compacted into one another such that the cross-sectional shape of said strands is deformed from an initial circular shape to a final non-circular shape; and a central fragile non-deformed optical fiber signal transmission element.
Claim 3
Independent Claim
57 words
A method of manufacturing a high tensile strength transmission cable from a pre-compacted multi-strand cable having a plurality of main strands surrounding a hard core wire including the sequential steps of opening the main strands, removing the hard core wire from the cable, inserting a relatively soft core containing a transmission element, and closing the main strands.
Claim 4
Independent Claim
57 words
A method of manufacturing a high tensile strength transmission cable from a pre-compacted multi-strand cable having a plurality of main strands surrounding a hard core wire including the sequential steps of opening the main strands, removing the hard core wire from the cable, inserting a relatively soft core containing a transmission element, and closing the main strands.
Claim 5
Dependent Claim
26 words
A method of manufacturing according to claim 2 including the additional step of encasing the cable in an electrical insulation sheath after closing the main strands.
Claim 6
Independent Claim
61 words
A method of manufacturing a high tensile strength transmission cable from a multi-strand cable having a plurality of main strands surrounding a hard core wire, including the sequential steps of compacting said main strands around said hard core wire, opening the main strands, removing the hard core wire from the cable, inserting a relatively soft core, and closing the main strands.
Claim 7
Independent Claim
61 words
A method of manufacturing a high tensile strength transmission cable from a multi-strand cable having a plurality of main strands surrounding a hard core wire, including the sequential steps of compacting said main strands around said hard core wire, opening the main strands, removing the hard core wire from the cable, inserting a relatively soft core, and closing the main strands.
Claim 8
Dependent Claim
56 words
A method of manufacturing according to claim 4 wherein the step of compacting the main strands includes compacting the strands until adjacent strands are bridged to contact each other and wherein the step of inserting a relatively soft core includes inserting a circular core element in the form of an electrical conductor or an optical fiber.
Claim 9
Dependent Claim
52 words
A method of manufacturing according to claim 4 wherein the step of compacting the main strands includes compacting the strands sufficiently to leave a space between adjacent strands and the step of inserting a relatively soft core includes inserting an insulation element having ribs which extend into the spaces between adjacent strands.
Claim 10
Dependent Claim
9 words
A cable made by the process of claim 2.
Claim 11
Dependent Claim
9 words
A cable made by the process of claim 3.
