Abstract
This invention improves on explosively actuated cable cutters in that it orporates a remote capability of activating the cutter. The improved apparatus comprises an acoustical transducer for receiving a remote coded signal, an electric circuit designed to detect the specific coded signal, a motor and gear mechanism which is initiated upon detection of the remote coded signal to activate the explosively actuated cable cutter. The electronics and motor compartment are hydrostatically sealed and pitted with a pressure switch and a water intrusion fail-safe circuit. The pressure switch is designed to inactivate the apparatus beyond a preset ocean depth, and the water intrusion fail-safe circuit is designed to detect any seawater seepage into the sealed electronics compartment. Upon the detection of such seepage the intrusion fail-safe circuit disconnects the system from the battery thereby removing danger of premature triggering of the cable cutter.
