Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
A composite high tensile strength towing cable, comprising: an outer cable structure formed of a plurality of strands, said strands having been initially of circular cross-sectional shape and having been compacted into one another while surrounding a central element, such that the cross-sectional shape of each of said strands is permanently deformed from said initial circular shape to a final non circular shape; and a central fragile non-deformed signal transmission element in intimate contact with and surrounded by said plurality of strands.
Claim 2
Dependent Claim
82 words
A composite high tensile strength towing cable, comprising: an outer cable structure formed of a plurality of strands, said strands having been initially of circular cross-sectional shape and having been compacted into one another while surrounding a central element, such that the cross-sectional shape of each of said strands is permanently deformed from said initial circular shape to a final non circular shape; and a central fragile non-deformed signal transmission element in intimate contact with and surrounded by said plurality of strands.
Claim 3
Dependent Claim
16 words
The cable of claim 1, wherein said signal transmission element comprises one or more optical fibers.
Claim 4
Dependent Claim
15 words
The cable of claim 1, wherein the central element comprises one or more electrical conductors.
Claim 5
Dependent Claim
12 words
The cable of claim 1, wherein said strands each comprises multiple strands.
Claim 6
Dependent Claim
13 words
The cable of claim 1, wherein said strands are of a metallic material.
Claim 7
Dependent Claim
17 words
The cable of claim 1, wherein said strands are of a nonmetallic material capable of permanent deformation.
Claim 8
Dependent Claim
56 words
The cable of claim 1 wherein said central signal transmission element is encased by an elongated ribbed core member of an insulative material having a central portion and a plurality of ribs extending radially outwardly from said central portion, said ribs extending outwardly between said strands, so as to electrically isolate said strands from one another.
Claim 9
Dependent Claim
20 words
The cable of claim 7 wherein said ribbed core member has one or more additional signal transmissive elements embedded therein.
Claim 10
Dependent Claim
20 words
The cable of claim 8 further comprising a sheath over the strands, the central element and the ribbed core member.
