Abstract
Abstract A communication cable winding is disclosed which is protected from heat, turbulence and friction during unwinding by a plastic skirt which surrounds a portion of the winding on a spool or bobbin. An outer portion of the cable may also be provided with a protective overlayer which forms the outer layer of the winding not protected by the plastic skirt.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
A missile and launching tube for deployment of a communication cable comprising a missile body having forward and rearward ends, a spool, mounted adjacent the rearward end of the missile body, a communication cable having a first end and termination end wound on said spool in a plurality of layers, connectors at each end of the cable, the termination end of the cable covered with at least one layer of plastic, a hollow bolt secured at the lower end of the launching tube and through which the termination end of the cable having the at least one layer of plastic is threaded, and a plastic blast protection skirt secured at the forward end of the spool to extend rearwardly over a portion of the cable wound on the spool.
Claim 2
Dependent Claim
129 words
A missile and launching tube for deployment of a communication cable comprising a missile body having forward and rearward ends, a spool, mounted adjacent the rearward end of the missile body, a communication cable having a first end and termination end wound on said spool in a plurality of layers, connectors at each end of the cable, the termination end of the cable covered with at least one layer of plastic, a hollow bolt secured at the lower end of the launching tube and through which the termination end of the cable having the at least one layer of plastic is threaded, and a plastic blast protection skirt secured at the forward end of the spool to extend rearwardly over a portion of the cable wound on the spool.
Claim 3
Dependent Claim
51 words
The invention as defined in claim 1, wherein the termination end of the cable having the at least one layer of plastic is formed into a helical coil positioned internally of the launch tube to provide additional resilience during the initial stages of launch of the rocket missile or mortar round.
Claim 4
Dependent Claim
41 words
The invention defined in claim 2, wherein the termination end of the cable having the at least one layer of plastic, the plastic comprising heat-shrink tubing and the helical formation is formed while the cable is still warm from heat shrinking.
