Abstract: A system and devices for publication of newspapers and the like. The system uses an electronic memory/display unit (24) which preserves the convenience of printed material, but which has the advantages of a computer display. The system utilizes a cable television (CATV) network to distribute the information. Data are transmitted over the system from a newspaper publication facility (2). The newspaper publication facility is provided with a data processing facility (4) that transmits newspaper data (6) to a satellite transmitting facility (8). The transmitted data are provided to a cable television satellite receiving station (12) by way of satellite link (14). Signal generators (16) are coupled to the satellite link and provide appropriate signals to a CATV network transmission facility (18). Network transmission facility (18) transmits newspaper signals over a CATV line (20) to a plurality of subscriber facilities (22) with the electronic memory/display units.

Abstract: A surge arrester has a single varistor element or a stack of varistor elements held between two end terminals by a plurality of elongate strength members disposed therearound. The ends of the strength members are inserted into recesses in the end terminals. Crimping of the end terminals distorts the recesses sufficiently to hold the strength members firmly therewithin, but without shearing and crushing (or otherwise damaging) the strength members.

Abstract: The invention provides for a method of making simple or complex extruded gel profiles and the created article. In a particularly preferred embodiment, the method involves the extrusion of a silicone gel composition through a die into a heated fluid to complete the cure of the gel as well as to produce the desired gel profile shape.

Abstract: An article (2) in which at least part of a surface (8) of a polymeric element has an embossed pattern (6). The article may be either heat-recoverable or non-heat-recoverable. If the article is heat-recoverable, when heated the article recovers and the embossed surface becomes substantially smooth. The change in surface texture can be used to indicate that sufficient heat has been applied to the article to achieve adequate recovery and/or to adequately melt an attached adhesive layer (10). In another embodiment, the article (2) is in the form of a patch (14) which can be used to secure the opposing longitudinal edges of heat-recoverable article which is in the form of a wraparound sheet.

Abstract: A terminator cap and system for using the terminator cap is provided for protecting a standard coaxial cable port from atmospheric conditions and from unwarranted tampering. The cap is a hollow cylinder with one enclosed end. The terminator cap is dimensioned to slip over one end of a connection jack connector, the other end of which has a plurality of attachment fingers dimensioned to fit over the connection jack. The swagging shell is used to firmly hold the terminator cap to the connection jack connector and firmly hold the flared fingers of the connection jack connector to the connection jack. A locking shroud is attached to the connection jack such that the locking shroud surrounds the connection jack, the connection jack connector, the terminator cap and the swagging shell.

Abstract: A fiber optic cable system, such as a preterminated fiber cable, includes a main cable and one or more drop cables connected to the main cable at spaced apart locations along the main cable. The drop cable is spliced to the main cable using a splice closure including a fiber guide that secures spliced together end portions of the respective fibers in a longitudinally extending direction and devoid of any slack coils of optical fibers. Accordingly, the overall diameter of the splice closure is relatively small thereby permitting the cable system to be stored on a reel and to be readily placed within small diameter conduits. The splice closure includes a heat recoverable housing surrounding the fiber guide. Cable sheath end portions are sealed by melting C-shaped bodies of heat flowable material positioned adjacent cable sheath end portions.

Abstract: Use of PTC circuit protection devices in motor vehicle wiring systems. The devices can replace some or all of the fuses conventionally used. Preferred devices contain PTC conductive polymers. Because the PTC devices can be reset without physical access to them, the wiring system can be arranged more efficiently and more economically. For example, the size of at least some of the wires of the harness can in many cases be reduced.

Abstract: An apparatus for sealing the end of an elongate cable such as an electrical heating cable which comprises a clip-shaped insert positioned within a tubular-shaped housing. Gripping members and pre-gripping members project from the interior surfaces of the arms of the insert and act to grip a cable when it is inserted into the device. A locking mechanism on the insert engages locking teeth on the housing and serves to hold the insert in position. A conformable gel component may be present. The apparatus provides high pullout force, as well as environmental sealing, for cables such as electrical heating cables or power cables.

Abstract: A feedthrough coaxial cable connector includes a tubular mandrel body dimensioned to be pressed between a foil-bonded dielectric core and other elements of an outer conductor of the prepared end of the cable. The body has cable engagement surface which defines a knife edge projection therearound for engaging an outer conductor of the cable by creating shear stresses therein without actually shearing the outer conductor. A tubular shank portion extends from the cable engagement surface portion to a radial wall portion, and a jack engagement portion is coaxial about the exposed central conductor. The jack engagement portion achieves a tight friction fit upon a jack and may be formed as an inside compression collet. A radial compression providing structure causes an inside surface region of the outer conductor to bear directly against and bend over the knife edge portion.
