Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
86 words
A cable for electrical communication comprising a pair of spaced-apart, relatively large cross-sectional DC currentcarrying conductors extending lengthwise within said cable; a third smaller cross-sectional communication signal-carrying conductor also extending lengthwise within said cable and spaced apart from said DC current-carrying conductors and forming with the same a triplate transmission line; and a plurality of repeaters also arranged within said cable at spaced intervals, each repeater having signal input and output terminals connected to said signal-carrying conductor, and power terminals connected to said DC current-carrying conductors.
Claim 2
Dependent Claim
86 words
A cable for electrical communication comprising a pair of spaced-apart, relatively large cross-sectional DC currentcarrying conductors extending lengthwise within said cable; a third smaller cross-sectional communication signal-carrying conductor also extending lengthwise within said cable and spaced apart from said DC current-carrying conductors and forming with the same a triplate transmission line; and a plurality of repeaters also arranged within said cable at spaced intervals, each repeater having signal input and output terminals connected to said signal-carrying conductor, and power terminals connected to said DC current-carrying conductors.
Claim 3
Dependent Claim
30 words
A cable as claimed in claim 1, wherein there are three conductors being inserted along the cable arranged as a triplate structure, the repeater elements being in the central conductor.
Claim 4
Dependent Claim
22 words
The cable as defined in claim 1 wherein said communication signal-carrying conductor is arranged symmetrically with respect to said DC current-carrying conductors.
Claim 5
Dependent Claim
20 words
The cable as defined in claim 3 wherein said communication signal-carrying conductor is arranged symmetrically between said DC current-carrying conductors.
Claim 6
Dependent Claim
21 words
The cable as defined in claim 1 wherein said spaced-apart conductors are insulated from each other by flexible, high-resistance, dielectric means.
Claim 7
Dependent Claim
17 words
The cable as defined in claim 5 wherein said flexible, high-resistance, dielectric means is comprised of polyethylene.
Claim 8
Dependent Claim
21 words
The cable as defined in claim 1 wherein each of said DC current-carrying conductors is essentially semicircular in transverse cross section.
Claim 9
Dependent Claim
20 words
The cable as defined in claim 7, wherein said communication signal-carrying conductor is arranged symmetrically between said DC current-carrying conductors.
