Abstract
Abstract A cable having an outer protective covering or sheath enclosing one or more insulated conductors and a cutting wire or rip cord intended for slitting the sheath, the cutting wire being attached to the sheath's inner surface and/or the core in order to prevent the cutting wire from slipping out of the cable.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
74 words
A cable comprising a core having at least one individually insulated conductor, an outer sheathing on said core, a wire for tearing the outer sheathing, said wire being interposed between the inner surface of the sheathing and the outer surface of the core, and an adhesive means joining said wire to at least one of said surfaces; the sheathing being substantially uniform in thickness throughout its extent inclusive of the location of said wire.
Claim 2
Dependent Claim
74 words
A cable comprising a core having at least one individually insulated conductor, an outer sheathing on said core, a wire for tearing the outer sheathing, said wire being interposed between the inner surface of the sheathing and the outer surface of the core, and an adhesive means joining said wire to at least one of said surfaces; the sheathing being substantially uniform in thickness throughout its extent inclusive of the location of said wire.
Claim 3
Dependent Claim
21 words
A cable as claimed in claim 1 wherein said adhesive means comprises an adhesive which becomes adherent in a heated state.
Claim 4
Dependent Claim
36 words
A cable as claimed in claim 2 wherein said wire is entirely encased under said sheathing and said sheathing includes means on the outer surface thereof for indicating the location of the wire beneath the sheathing.
Claim 5
Dependent Claim
29 words
A cable as claimed in claim 3 wherein the location indicating means on the sheathing comprises a pair of longitudinally extending, spaced, projecting ridges between which said wire extends.
Claim 6
Dependent Claim
24 words
A cable as claimed in claim 1 wherein said wire is pervious to said adhesive means and said adhesive means extends into said wire.
Claim 7
Dependent Claim
110 words
A process of manufacturing a cable comprising mounting a tear wire on a core having at least one individually insulated conductor therein, applying a heat-sensitive adhesive to said wire, applying an outer sheathing onto said core and wire in a heated condition to render the adhesive adherent to cause the wire to be adhered at least to one of the inner surface of the sheathing and the outer surface of the core, and allowing the sheathing and adhesive to cool whereupon the wire is bonded in the cable by the adhesive, and the cooled adhesive no longer has adhesive capability apart from the bonding of the wire in the cable.
Claim 8
Dependent Claim
110 words
A process of manufacturing a cable comprising mounting a tear wire on a core having at least one individually insulated conductor therein, applying a heat-sensitive adhesive to said wire, applying an outer sheathing onto said core and wire in a heated condition to render the adhesive adherent to cause the wire to be adhered at least to one of the inner surface of the sheathing and the outer surface of the core, and allowing the sheathing and adhesive to cool whereupon the wire is bonded in the cable by the adhesive, and the cooled adhesive no longer has adhesive capability apart from the bonding of the wire in the cable.
Claim 9
Dependent Claim
24 words
A process as claimed in claim 6 wherein said heat-sensitive adhesive is applied to said wire before the wire is mounted on said core.
Claim 10
Dependent Claim
22 words
A process as claimed in claim 7 wherein said wire is pervious to said heat-sensitive adhesive and said adhesive impregnates said wire.
