Abstract: A machine for application of two-part electrical connectors to multiconductor flat cables has connector magazines for feeding connector bodies and covers to a pre-application station seriatim, and a connector pusher bar for moving a body and a cover from a pre-application station to an application station, one connector part above and one below a flat cable path through the application station. The upper connector part is supported and guided between a pair of plates, one of which has its lower edge inclined toward the opposing plate to provide support for the connector part between the plates, and the plates are resiliently movable apart to permit a platen to push the upper connector part past the inclined support edge and to press it into engagement with the flat cable and the other connector part to complete the application.

Abstract: A storage box which can be easily modified to store flat, rectangular objects with a plurality of different widths and thicknesses is disclosed. The storage box consists of a rectangular housing member which has a plurality of straight tracks mounted on the inside surfaces of the housing ends. Two rack members may be slid into the housing along the tracks and are held in position by hooks molded into the back of the housing. Each rack member has a planar central portion with a set of ribs mounted on each side of the central portion. Within each set, the ribs are equally spaced ribs, but the spacing between the ribs differs between sets. The rack members are arranged so that when both members are inserted into the housing the spaces between the ribs form a slot into which an object to be stored may be inserted.

Abstract: A single use thermal switch having a tubular casing within which a mechanical isolation cage is axially movable. The cage is normally urged by a helical compression spring against a fusible pellet which melts at a temperature at which it is desired to disconnect the electrical circuit. An electrically conductive contact member extending transversely through the isolation cage is normally urged by a helical compression spring toward one end of the cage and against the end of one electrical lead that is coaxial with the casing. The contact member is foldable along a line across its center. The force of the contact member pressed against the end of the lead urges the contact member to fold to cause the ends thereof to be forced against the inside wall of the casing to establish electrical connection between the casing and the lead through the contact member.

Abstract: A multi-core cable connection for medium voltage cables in which each core connection includes a pair of prefabricated permanently elastic stress control elements, each of which has a sleeve-like main body of insulating material and a conductive sleeve-like insert in the body, extending out of one end thereof and bridging the core insulation and the conductor connector.

Abstract: A method for making a molded high voltage splice body by positioning a conductive elastomeric electrode on a mandrel, positioning an extruded conductive elastomeric sleeve over the elastomeric electrode, sealing the ends of the elastomeric sleeve, placing the mandrel with the electrode and sleeve on it into a mold, injecting a curable insulating compound between the electrode and the sleeve under pressure and curing the insulating compound.

Abstract: Connections to one or more wires of a flat cable are made with connectors having contact elements each with two bifurcate contact members extending to different heights and at right angles to each other from a common base. One contact member contacts a wire of the cable. The other member penetrates the cable parallel to that wire and contacts a connecting wire. Cutting means for severing the cable wire may be included.
