Gage provides audible signal to facilitate checkout of connector pins

Commercial push gage has been modified to enable rapid, accurate testing of paddle pins in distributors, bullet pins and patch boards. The purpose of the gage is to ensure that the pins will not break electrical contact when they are subjected to a minimum, preset pressure.

Leakage tester for flat conductor cable connector

U-tube containing liquid indicates pressure differences in a leakage tester. This tube, connecting two containers, indicates that the amount of leakage over a set period of time is calculated from the pressure and gas volume.

Improved shielding termination adapter for electrical cable connectors

Termination adapter replaces braid ring and ensures permanent attachment and grounding of sheath wires. The inner ferrule of the termination is slipped inside the exposed ends of the sheath wires and the outer ferrule is placed over the wires and crimped in place to secure the wires for grounding.

Heart catheter cable and connector

Ultraminiature catheter cables that are stiff enough for intravenous insertion yet flexible at the tip, sterilizable, and economical are fabricated entirely from commercially available parts. Assembly includes air passageway for reference pressures and coaxial cable for transmission of signals from the tip of catheter.

Materials investigation and tests for the development of space compatible electrical connectors

A molding study of compounds based on copolymers of highly fluorinated olefins and of flame retardant silicone is reported. Both single cavity and four cavity molds having size 22 and 24 holes with three webs in each hole were used. Also covered are dielectric strength, arc resistance, Bashore rebound, and maintenance aging tests on the various materials that have been successfully molded.
