Abstract
In a system for suspending an immersible package in water from a surface buoy with insulated electrical cable payed out from a coil in a pack attached to the descending package, a spring-biased braking arm on top of the pack is released to pivot against a center post (around which turns of coil are payed out) in response to a signal generated in the package at the required depth to brake descent of the package. Another signal generated in the package (after sufficient delay for the braking action to be completed) releases a spring-biased block against the cable in a guide just beyond the braking arm. The released block shoves the cable against conductive pins connected to a shunt lead from an electrical circuit in the package with sufficient force to cause the pins to penetrate the cable insulation. A viscous nonconducting material (coated on the cable to aid in holding turns of the coil in place in the pack until pulled as cable is payed out) is scraped off by the cable guide and accumulated around the penetrating pins to seal the connection between the pins and inner conductor of the cable after penetration.
