Abstract: 1413311 Cables with provision for branching BRITISH INSULATED CALLENDERS CABLES Ltd 3 May 1973 [4 May 1972] 20890/72 Heading H1A [Also in Division H2] A distribution cable with power conductors 1 and neutral conductor 2, together embedded in a single insulating rubber or plastics body 3, has branch conductors 9, 11, permanently connected, prior to installation, at spaced locations, where the branch joints are embedded in a further insulating body 12, integral with, or bonded to, the main insulating body 3. Branch conductors may extend as single-phase consumer service cables, either of full length to reach the consumer's installation, or of short length with a connector to which a service cable can be coupled, and for these purposes coaxial branch cables 4 may be used, each with its outer conductor 7 joined to the neutral conductor 2. Alternatively, the neutral branch conductors (28), Fig. 2 (not shown), may be separated, and either twin-core insulated cable (not shown), or separate insulated single-core cables (24) may extend, for connection to consumer installation equipment, or to group fuse cut-out boxes serving several customers. In another embodiment, a coaxial connector, with its outer contact connected to neutral, is fitted at the branch joint location, and is wholly embedded in the protective insulating covering, with means provided for indicating its location, and for identifying the phase to which its inner contact is joined. Each of the cables may carry coloured or other markings to identify the phase lines. Each of the conductors may be solid or stranded. The branch conductors are preferably welded in place. The neutral conductor may comprise a plurality of conductor elements arranged to surround the core conductors.

Abstract: 276,325. Stettiner Chamotte-Fabrik Akt.-Ges. vorm. Didier. Aug. 17, 1926, [Convention date]. Discharging; doors. - A cokereceiving hopper 7. adapted to travel along a bench of coke ovens 13 above bunkers 9, is combined with apparatus for operating the oven doors 12. there being arranged between the two parts of the apparatus a flexible connection which allows when the hopper is stationary, a limited movement of the door operating device so that it can automatically adjust its position in relation to the door to be opened. As shown. the hopper carriage carries a motor 14 for actuating the winding-gear of a cable 2 which is connected to the door 12 and passes over a guidepulley 1, the latter being adapted to run on an overhead rail 3 secured to the oven framework 5 and being connected to arms 10 projecting from the upper end of the hopper 7 by chains 11 which hang loosely when the pulley is midway between the arms 10. In operation, when the hopper 7 is moved on the rails 8, the forward chain 11 becomes taut and the pulley 1 is traversed along the rail 3: the cable 2 is then attached to the door 12 to be opened and on actuation of the winding gear the pulley 1 automatically centres itself between the arms 10.

Title: Improved carbon and graphite bodies and process for preparing same
Inventor: THOMAS EDWARD CARL
IPC: C04B35/52
Filed: 1961-06-12
Abstract: In the production of threaded graphite nipples for joining electrode sections, comminuted needle-like coke and a pitch binder are extruded, baked and graphitized, and the extruded shape is allowed or caused to expand transversely to increase the transverse dimensions such that after graphitizing the ratio of transverse to longitudinal coefficients of thermal expansion is within the range 1.2-1.5.  The plastic mixture of pitch and coke is extruded preferably through a cylindrical die having a diameter between 20-30 cm., and an internal contour resembling the Schiele anti-friction curve.  The extrusion die may also be rifled and have an enlarged section of substantially uniform diameter at the end of the straightway section of the die such that, when the extrusion is started, the open end of the enlarged section is plugged and the mixture extruded until the enlarged section is completely filled, after which the plug is removed and the extrusion continued. The extruded product in the plastic state may be axially aligned in a container or mould, which tapers towards its ends and has such dimensions as to allow compression in the longitudinal direction. After baking the nipple may be re-impregnated and baked one or more times. Specification 829,196 is referred to.

Abstract: 1422947 Electric couplings BICC Ltd 8 May 1973 [8 May 1972] 21407/72 Heading H2E A method of making a fluid-tight joint between the end of a metal sheath of a cable and a metal body (for example, another sheath or a joint of termination enclosure) having a throughbore, comprises shaping a length of sheath adjacent the end such that it is radially spaced from the cable core, either inserting a length of the body into the space between the sheath and core or inserting a tubular metal mandrel into the space and arranging a length of the body to overlie the said length of the sheath, and circumferentially compressing the overlying lengths of sheath and body, and mandrel if present, radially inwardly. The end wall 1 of a joint enclosure has a sleeve 2 which is positioned between the radially-stretched length 3 of a corrugated aluminium sheath 3 and the cable core, and an alumium sleeve 7 is permanently compressed to retain the joint. The sleeve 2 is serrated at 6 and has grooves 4 holding 0-rings 5. A temporary poultice 10 prevents the escape of insulating fluid from the core during the jointing process. In the embodiment of Fig. 2 (not shown), the joint enclosure sleeve surrounds the sheath and is serrated on its inner surface, therebeing a mandrel (18) with two circumferential grooves (19), 0-rings being positioned between the sheath and joint enclosure sleeve to overlie these grooves. Circumferential clamps (Fig. 4, not shown) may be used instead of the sleeve 12. The joint-enclosure sleeve may also include flat bottomed grooves (44, Fig. 5) housing flat rubber seals (48), or other flat bottomed grooves (54) into which the sheath and an overlying sleeve are compressed. In Fig. 3 (not shown) the end of the sheath folded back on itself and the sleeve is positioned between the overlying portions of sheath.

Abstract: 597,554. Buffer mechanisms. MINER, Inc., W. H. Aug. 22, 1945, No. 21512. Convention date, Sept. 15, 1944. [Class 103 (v] In a buffer for a railway vehicle in which the initial shock is absorbed by springs and subsequent shock by a friction wedge-action, the friction casing 17 containing the friction shoes C is integral with the buffer head 18 and is maintained in the housing A by co-operating lugs 20, 13. In the initial movement the spring E separating the wedge D from the housing A is compressed. Subsequently a shoulder 29 on the wedge D abuts against a guide sleeve 15 so that further motion causes wedge D to expand the shoes C into frictional engagement with the casing 17. The shank 28 of the wedge D and the guide sleeve 15 receiving this shank are hexagonal in transverse section, as is the head of the wedge D. The shoes C are V-shaped in transverse section and slidingly engage both the wedge D and the hexagonal section inner surface of the casing 17. Lugs on the wedge D fit between the shoes C and co-operate with lugs on the casing 17 to prevent separation of the wedge and casing.
