Abstract
Abstract Multiconductor cable comprising a plurality of metal wires of high unit tensile strength, at least two wires fulfilling wholly or in part the function of an electrical conductor, a core withstanding the mechanical forces to which the cable is subjected when it is unwound, certain of the multiple wires being grouped to form a multi-strand single-channel conductor in which the mechanical strength and the electrical resistance are locally distributed at distinct location, said cable receiving a plastic protective coating obtained by extrusion or impregnation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
A remote-control multiconductor cable for command-guided missiles comprising a steel core means to withstand the mechanical forces to which the cable is subjected when it is unwound, at least two electrical conductor wire means wound helically about said core means to form a multi-strand single channel conductor with mechanical strength and electrical resistanCe locally distributed at distinct locations, each said electrical conductor wire means being a steel wire means having a diameter substantially in the range of 0.05mm to 0.1mm and having a copper coating thereon and further coated with an insulating deposit whereby the electrical resistivity of said electrical conductor wire means is relatively lower and the mechanical strength and yield strength of the cable as a whole is relatively higher than that of a single wire of identical cross-section.
Claim 2
Dependent Claim
131 words
A remote-control multiconductor cable for command-guided missiles comprising a steel core means to withstand the mechanical forces to which the cable is subjected when it is unwound, at least two electrical conductor wire means wound helically about said core means to form a multi-strand single channel conductor with mechanical strength and electrical resistanCe locally distributed at distinct locations, each said electrical conductor wire means being a steel wire means having a diameter substantially in the range of 0.05mm to 0.1mm and having a copper coating thereon and further coated with an insulating deposit whereby the electrical resistivity of said electrical conductor wire means is relatively lower and the mechanical strength and yield strength of the cable as a whole is relatively higher than that of a single wire of identical cross-section.
Claim 3
Dependent Claim
51 words
A cable according to claim 1, characterized in that the stranding is effected at a sufficiently close pitch of the order of a few millimeters, whereby cable homogeneity is obtained by the tightness of the winding and the cable retains its structural stability in the event of rupturing of a strand.
Claim 4
Dependent Claim
19 words
A cable according to claim 1, characterized in that said cable has a covering and a plastic protective coating.
Claim 5
Dependent Claim
24 words
A cable according to claim 3, characterized in that the protective plastic is selected from the group consisting of polyvinyl chloride, nylon and silicone.
Claim 6
Dependent Claim
33 words
The remote-control cable according to claim 1 further characterized by the cable including said core means and said electrical conductor wire means having a weight of not more than .380 grams per meter.
