Abstract
Abstract A flexible electrical cable for transmitting control signals between a control station and a rapidly moving aerodynamic body includes at least two parallel enamel-insulated conductor wires cemented together in parallel relation and extending centrally through a tension member formed by a large number of thin individual filaments, and further includes a covering closely embracing the wires and the tension member and comprising superposed layers wound around the tension member in opposite respective angular directions.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
98 words
In a flexible electrical cable for transmitting control signals between a control station and a rapidly moving aerodynamic body, and including at least two parallel enamelinsulating conductor wires imbedded in a tension member formed by a lArge number of thin individual filaments, and a covering closely embracing the conductor wires and the tension member: the improvement comprising said conductor wires being cemented together in parallel relation and extending centrally of said tension member throughout the length of said cable; said covering comprising superposed layers of covering material wound around said tension members in opposite respective and angular directions.
Claim 2
Dependent Claim

In a flexible electrical cable for transmitting control signals between a control station and a rapidly moving aerodynamic body, and including at least two parallel enamelinsulating conductor wires imbedded in a tension member formed by a lArge number of thin individual filaments, and a covering closely embracing the conductor wires and the tension member: the improvement comprising said conductor wires being cemented together in parallel relation and extending centrally of said tension member throughout the length of said cable; said covering comprising superposed layers of covering material wound around said tension members in opposite respective and angular directions.
Claim 3
Dependent Claim
81 words
In a flexible electrical cable, the improvement claimed in claim 1, in which said conductor wires consist of electrolytic copper of the greatest possible purity with an elongation equal to at least 25 percent and having, in the bare condition, a diameter of 0.07 mm., the tension member consisting of n-parallel filament strands of 14 Mu diameter polyester fiber having an elongation of approximately 7 percent to 8 percent, and the covering comprising natural silk of composition 4 x 13/15 den.
