Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
99 words
A hybrid cable construction having an axis and windings which comprises a plurality of optical fibers helically wound with a plurality of sheathed metal conductors formed of a metal core surrounded by an adherent sheath of fiber-reinforced resin, the optical fibers and sheathed metal conductors wound in the cable to a lay angle which substantially satisfies the expression: ##EQU3## wherein R c =radius of curvature of a given winding of the cable and is greater than 5 cm; Pitch Diameter=diameter of the cable at a given winding; and θ=lay angle of a winding to the axis of the cable.
Claim 2
Dependent Claim
99 words
A hybrid cable construction having an axis and windings which comprises a plurality of optical fibers helically wound with a plurality of sheathed metal conductors formed of a metal core surrounded by an adherent sheath of fiber-reinforced resin, the optical fibers and sheathed metal conductors wound in the cable to a lay angle which substantially satisfies the expression: ##EQU3## wherein R c =radius of curvature of a given winding of the cable and is greater than 5 cm; Pitch Diameter=diameter of the cable at a given winding; and θ=lay angle of a winding to the axis of the cable.
Claim 3
Dependent Claim
30 words
A hybrid cable construction as claimed in claim 1 in which the fibers of the fiber-reinforced resin are fibers selected from the group consisting of glass and aromatic polyamide fibers.
Claim 4
Dependent Claim
22 words
A hybrid cable construction as claimed in claim 1 in which the resin of the fiber-reinforced resin is a thermoset epoxy resin.
Claim 5
Dependent Claim
