Abstract: A portable coaxial cable trimmer (10) for trimming coaxial cable (12) with shielding (36), insulation (38), and a conductor (40) comprises a hollow, elongated housing (18) with a laterally disposed port (44). A first bushing (22) is attached to the end of the housing (18) for centering the cable (12). A first cutter (30) is secured in the housing (18) for trimming the insulation (38) and shielding (36) to produce a shaving (42) which is discharged from the housing (18) through a port (44). A second bushing (46), secured in the housing (18), centers the exposed conductor (40) of the trimmed cable (12). A second cutter (48) disposed in the housing (18) rounds and cuts the end of the exposed conductor (40). A device for rotating the housing, such as an air drill or an electric drill (14) can be attached to the cable trimmer (10) for rotating the housing (18) with respect to the cable (12).

Abstract: A continuous loop tape cartridge including a housing in which an endless tape is wound as a coil on a main hub disposed within the housing. During operation the tape is withdrawn from the center of the coil and wound onto the outside of the coil. A rewind hub is coaxially mounted with respect to the main hub and includes an accessible portion adapted to be driven to rewind the tape from the outer convolution of the coil onto the rewind hub.

Abstract: A vibration isolation module is interposed between a sonar array and its ing cable. A number of nylon cords contained within the vibration isolation module normally bear the load induced by the hydrodynamic drag of the array. Since the nylon cords are encased in a rubber-like envelope, noise and vibrations created by the towing cable are damped and prevented from overly interfering with the responsiveness of the sonar array. When, however, the array's drag is increased by, for example, a faster towing speed, the cords stretch and a central braided member bears the load. The braided member has a strength considerably in excess of the nylon cords to assure that the towed sonar array is not lost. Since the braided member is filled with a viscous material and there are no other voids in the rubber-like envelope, the module can be pulled through a hull penetrator to deploy or retrieve the sonar array.
