Cable run circuit with switching junction connectors at strategic locations enables television cameras to be plugged in with minimum effort wherever needed. Crimp-type contacts for mating connections reduce installation time and require a lesser level of technician skill than do soldered and potted connections.
Modified single-tube hole punch or grommet-setting pliers couples or uncouples spring-loaded bayonet-type connectors quickly and easily. The anvil and tube or punch of the single-tube hole punch or pliers are removed and an open-end slot is machined in the tips of the jaws.
Conversion coating procedure repairs scratched and abraded cadmium-plated aluminum cable connectors while they are in assembly.
An orbital tube flaring system produces tubing connectors with a zero-leak potential needed in high pressure hydraulic and pneumatic systems. The flaring system incorporates a rolling cone and rolling die to closely control flare characteristics.
Electrical noise measurement system measures noise generated by edge-type connectors and circuit cards when they are subjected to sinusoidal vibration. It provides a signal across the contact area and monitors the signal change during vibration. Noise measured can be expressed as a varying change in total contact resistance.
Thermal sterilization effects and application parameters determined for connector cup joints soldered with tin and antimony
Connector plug automatically minimizes arcing during mating and demating. This plug uses a high-resistivity outer sheath as an extension to the regular pin contact. It is used in atmospheres containing explosive gases, and reduces erosion at the contact surfaces where mating and demating are performed frequently.

Glass vacuum systems grease free assembly method using heat shrinkable polyolefin sleeve tubing connector for compression of O ring joints
Electrical connector is fitted with an O ring, moisture-proof seal, is shielded in both the mated and unmated positions, and is equipped with one keying and three locking spheres.
Connector is modified by machining the cone from one end before the fitting is bored to accommodate a metallic-filament type of slip-in filter. Thus, when surface of the cone is damaged, only the cone needs replacement.
Connectors, which have 4 to 9 contacts, are engaged through a hole with a minimum diameter of 0.030 inch. They are constructed of concentric brass and nylon components assembled with a light, firm press-fit. They withstand several thousand mating cycles and each outer contact has a one ampere capacity.
