Abstract: This invention relates to an electrical connector assembly including apparatus for securing a metallic coupling ring on a connector body or shell. A metallic retaining ring is secured into the rear of the coupling ring bore through the interaction of an annular sawtooth groove pattern formed on the outside of the retaining ring and on the rear inside of the coupling ring bore. The dimensions of the sawtooth groove pattern are carefully selected so as to permit metallic materials to be used for both rings. The connector assembly includes a pair of shells, each having electrical contacts carried by a dielectric retention disc secured in a respective shell for engagement with the electrical contacts of the other shell. Each shell has a large diameter recess for receiving a large diameter portion of each disc force fit through a small diameter portion of the respective shell to thereafter retain the disc.
Abstract: An apparatus for concentrically aligning and terminating an optical fiber within the terminal end of a fiber optic connector includes the use of a resilient jig having a bore dimensioned for receiving the optical fiber. The jig is aligned relative to the connector so that the jig bore is concentric to the outer dimension of the connector terminal end. The resilient jig is uniformly compressed in a chuck to cause the jig bore to contract about an optical fiber threaded through the connector and the jig bore. As a result, the optical fiber is firmly held in concentric alignment to the outer dimension of the connector terminal end for subsequent curing of adhesive material within the connector for terminating the optical fiber to the connector.

Abstract: An electrical contact member formed from an axially extended tube is provided intermediate its ends with an axially extending insulation-opening slot. The slot is terminated at one end in an entry opening through the tube. The entry opening and an inwardly tapered entry ramp are formed by a free-ended piece of the tube wall bent into the inner opening of the tube. An insulated conductor may be inserted into the contact member in either of two ways: by insertion through the appropriate end of the tube and deflection by the entry ramp through the entry opening; or, by insertion through the entry opening and deflection by the entry ramp through the end of the tube. After insertion by either method, the ends of the insulated conductor may be pulled to force the conductor into a narrowed engagement portion of the slot where the insulation around the conductor is opened by spreading or cutting and electrical contact is made between the tube and the metallic conductor.

The connector includes an outer metallic shell, a dielectric body within the shell and at least one network filter contact assembly. The inner body has at least one through channel and a transverse cavity which communicates with the shell and the channel. The network filter contact assembly has a ground electrode and a pin electrode and is disposed within the portion of the channel bridging the cavity. Conductive curable filler material is charged into the cavity around and in contact with the ground electrode to efficiently and inexpensively establish a ground plate for the connector. A retention means disposed within the channel and a locking means carried by the contact cooperate to provide axial strain relief, thereby protecting the bond between the conductive filler material and the ground electrode.
Abstract: A linear sensor array is deployed horizontally on the ocean floor by first deploying a vertical array, between an anchor and a float from which the array is suspended, and then decreasing the buoyancy of the float gradually as the float is carried away from the anchor by ocean currents. The float is comprised of a suitably large volume of buoyant material such as hollow glass microspheres freely floating inside a liquid filled plastic container. To gradually reduce buoyancy, the microspheres are allowed to flow out through a neck near the top of the container while water is allowed to enter the bottom of the container through a liquid permeable membrane. The diameter of the neck is selected for optimum sinking rate of the float.
