Abstract: A cable splice formed by wrapping an electrical connection in sealing tape and injection molding an encapsulation on the connection. The sealing tape is formed of material (e.g. ethylene propylene rubber) which softens under the influence of the injection molding temperature, and is shaped intimately into fluid-tight sealing contact with the electrical connection by shrinkage of the encapsulation during cooling. The material of the sealing tape is also heat insulating to resist increase in temperature of the insulated conductors within the cable during the injection molding process.

Abstract: To connect two bus bars to two sets of cables which are bunched to produce a low stray field, a connecting piece is provided, in which parallel, electrically conducting, plates are provided with angled-off connecting straps and connecting lugs, the connecting straps being connected to the bus bars and the connecting lugs being connected to the cable ends by means of cable terminals.

Abstract: A telecommunications cable provided with an electrically conductive adaptor for grounding purposes. The adaptor is factory fitted to the cable shield and an electrically insulating encapsulation extends around the adaptor and cable in the vicinity of the adaptor while rendering the adaptor accessible from outside for connection of a grounding extension. In practice, a cable is provided with a plurality of spaced adaptors along its length. Field splicing is eliminated with use of the construction for aerial cable and aerial installation is simplified and made cheaper.

Abstract: An improved cable fitting which consists of a material which is shrinkable under the influence of heat and which has at least one sealing area provided with a sealing device including adhesive agents which are also influenced by heat characterized by the sealing device being a permanent plastic sealing member which is disposed between two adhesive layers. The sealing area of the fitting may be a closure area which has a separation plane defined by a pair of flanges and/or may be a socket-like area or opening in which a cable is inserted through. In either instance, the improved sealing device ensures the required mechanical stability through the use of the adhesive layer and the permanent plastic sealing member or insert ensures sealing against humidity.

Abstract: A predetermined block system for use in outside underground utility distribution networks, such as networks for providing telephone service, includes factory installed cable stubs spliced into a main distribution cable and encapsulated at predetermined intervals along the length of the distribution cable. The free ends of each cable stub are attached to one side of a terminal block which is adapted to be mounted in an aboveground or flush to the ground closure. Service wires may then be attached to the other side of the block. The cable stub includes a pair of bond wires insulated from each other. At a splice opening formed in the distribution cable one bond wire is connected to a field side and the other bond wire is connected to the central office side of the cable shields of the distribution cable. The bond wires terminate at commonly grounded terminal posts in the terminal block. The common ground may be provided by a ground braid fastened to the closure.

Abstract: An electrically conductive connector adapted to be releasably coupled with a stud to form an electrical connection. The connector includes an electrical terminal with an electrically conductive terminal aperture. The aperture has a larger diameter than the stud so as to facilitate introduction of the stud therein. A set screw is threadedly mounted on the electrical terminal in position to be actuated from the exterior of the electrical terminal and to be reciprocally passed across the aperture to engage the stud inserted therein and form a fixed electrical connection between the stud and connector. Release of the set screw permits the stud to be removed from the connector. The aperture has a configuration to permit it to cooperate with the set screw and stud to stabilize the interconnection therebetween. This is particularly true when the connection is subjected to forces acting other than along the axis of the set screw that otherwise could cause loosening of the interconnection between stud and connector.

Abstract: A connector for a plurality of electrical devices, particularly switches and receptacles, to be installed adjacently or on top of one another in flush receptacle boxes. An insulated flat conductor has a required number of wires for at least two independently actuated installation devices. The flat conductor is connectable to a power supply line and to connecting lines. Contact blades are placed at predetermined intervals, required for the installation devices, on the wires. Tapping points are formed by the contact blades and are backed up by a support for the flush receptacle boxes and projecting beyond the flat conductor. The flush receptacle boxes are provided with a cut-out bottom area. The contact blades, moreover, have an easily detached insulation, and the wires have terminals for connecting to a power supply line and a connecting line. The support may be tub-shaped, and the wires may be fused in the support which may extend over the length of the connector.

Abstract: The invention relates to a method for laying carrier cables, more particularly telephone lines, comprising the steps of burying a bundle of pipes connected to a connection box supplied by a main cable, severing certain of the pipes forming part of the bundle to constitute a local opening therein at the suitable spot, connecting one end of a secondary connection pipe to the severed opening of the pipe forming part of the bundle, the opposite end of said secondary connection pipe terminating at the apparatus to be supplied, passing a secondary branch cable in the severed pipe extended by the secondary connection pipe, one side of which cable thus terminates at the connection box and the other at the apparatus to be connected to the system. The invention also concerns a bundle of pipes for carrying out the method.

Abstract: The invention provides an air tight and water tight seal around a telephone cable that has been opened and has a number of pairs selected and spliced to wires or cables exiting from the splice. The seal extends over and around the cables exiting from the spliced joint. This is accomplished by encapsulating the cable with a molten material which seals to the cable sheaths.

Abstract: Strip supply lead comprising a plurality of conductors embedded in a suitable insulating material (typically, a plurality of generally flat conductor elements in a strip of suitable polymeric material) is provided with a branch lead by first removing a portion of the insulating material in a zone intermediate the ends of the strip supply lead to expose a length of at least one of the conductor elements. The strip supply lead is folded about the midpoint of the bared conductor into a generally "U" shaped configuration to bring the surfaces of the portions on the intact strip supply lead immediately adjacent either end of the bared length of conductor forming the extremities of the shank of the "U" into an opposing relationship.

Abstract: A grounded surface distribution apparatus and system is provided including elastomer encapsulated cable terminals, joints, taps, load-break switches, current limiting fuses and surge protectors, each enclosed completely within a metal sheath combined in various arrangements to perform operational functions required in loop and radial underground distribution systems.
