Title: Improvements in or relating to Time Division Multiplex Circuits
Inventor: GARA GEORGE
IPC: H04Q11/04
Filed: 1968-04-10
Abstract: 1,194,479. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. 10 April, 1968, No. 17378/68. Heading H4K. In a telephone exchange employing time division multiplex transmission over a highway separate portions of each time position in the multiplex cycle are used for conveying speech, for supervising the condition of the highway, and for receiving signals from the highway. The arrangement shown is similar to that used in Specification 1,155,805, and shows transistor cross-points VT1 and VT3 in successive switching matrices. The connecting path is routed through these cross-points by simultaneously biasing the bases of these transistors to conduction. The time slots are separated by short pauses during which inhibiting signals BS4 are applied to a gate G3 which normally passes the biasing pulses XS. This ensures that the crosspoint switches such as VT1 are closed during the inter-channel pause and allows a pulse BS5 to be applied to line via a transistor VT6 so as to discharge the line as described in the abovementioned Specification. The cross-point VT3 is closed during the inter-channel period by the inhibit pulse BS4 and during the supervisory and signalling periods by timing pulses BS7 and BS8, respectively. These are short duration pulses timed to occur at different instants near the beginning and within the active portion of each time position. Each time the transistor VT3 is blocked by the pulses BS7 and BS8 (while the transistor VT1 is conducting) current drawn to the highway causes a transistor VT5 to switch to saturated conduction connecting the line to a pair of gates G1 and G2. The gate G1 is opened by the first pulse BS7 during the supervisory period while gate G2 is opened by the second pulse BS8 during the signalling period. Tone signals Ts may be applied to line via a transistor VT7.

Title: Twistless staple yarn and method of manufacturing the same and apparatus for use in connection with such manufacture
IPC: D02G3/40
Filed: 1954-06-15
Abstract: 764,002. Yarns: sliver rubbing apparatus. FIBERBOND LABORATORIES, Inc. June 15, 1954, No. 17488/54. Classes 120 (1) and 120 (3). Adhesively-bonded yarns composed of staple fibres are produced by aligning the fibres in parallel relation, pressing them against an adhesive-applying surface and passing them between rollers or other means providing a rubbing action, whereby lateral fibres are gathered towards central fibres. One method of producing the yarns comprises drawing the fibres into substantially parallel relationship by means of drawing rollers 30, conveying them as a thin ribbon to rolls 47, 48 where they are impregnated with adhesive, such as rubber latex, and rubbing the fibres to consolidate them by means of a cork-surfaced roll 46 that has both reciprocatory and rotary motions. A further slight draft is given at 36 before drying the fibres at 38. Further rubbing actions take place at 40 and 44 and the yarns are pressed at 42 to consolidate them. Consolidation may be accomplished by pressing the yarn or strand in a mould, by rolling it between two hard surfaces, by passing it through a continuous press, or by passing it between rolls adapted to force the yarn into a narrow groove. In a modified arrangement, the adhesive is applied from a roller rotating in a liquid bath and the second drawing step is replaced by another rubbing step. One machine that may be employed, Fig. 8, has five reciprocating rolls 139 that work in conjunction with a larger roller 138 which is partially immersed in a bath of adhesive. Although it is preferred to provide strokes of the same amplitude for each roll 139, strokes differing in length may be used.

Abstract: Porous polyethylene is produced by subjecting small particles of polyethylene of molecular weight greater than 75,000 to heating at a temperature not less than 120 DEG  C. and which is below the temperature at which decomposition and/or gelation of the polyethylene occurs.  Another polymer may be mixed with the polyethylene before heating, specified polymers being polystyrene, polyisobutylene and low molecular weight polyethylene.  The small particles may be in pulverulent form or may be granules, fibres, scales, flakes, rings, discs, wire sections, tube sections, plate sections, or small polyhedrons or mixtures thereof and may be mixed with dyes and fillers.  The heating may be effected in the absence of air or oxygen, e.g. in an inert gas such as nitrogen or carbon dioxide, under a vacuum, and with or without pressure.  The heating may be effected in two or more stages, by recesses attached to the outside walls of the reaction vessels, by passing a preheated inert gas or vapour through the polyethylene or by means of a high-frequency electromagnetic field when the polyethylene is mixed with a dielectric loss high polymer or filler.  The surface of the porous product may be rendered impermeable by partial oxidation, e.g. in a current of air at 170 DEG  to 200 DEG  C.ALSO:Porous polyethylene is produced by subjecting small particles of polyethylene of molecular weight greater than 75,000 to heating in a mould at not less than 120 DEG C. but below the temperature at which decomposition or gelation of the polyethylene occurs.

Abstract: 1199548 Super-conductors SIEMENS A G 8 April 1968 [6 April 1968] 18039/69 Headings H1A A5 and A4D A plurality of composite conductors, each comprising a plurality of super-conductor wires embedded in Cu, are closed in an Al sheath. The super-conductor material may be a Nb-Ti alloy, a plurality of wires 5 of which are embedded in a stabilizing sheath 2 of Cu. A plurality of such composite conductors are assembled together with steel strengthening wires 3 and an Al sheath 1 is extruded round them to form a strip conductor. The extrusion may be performed at an elevated temperature or the completed strip may be heattreated to form an Al-Cu eutectic metallurgical bond between the Cu stabilizing material and the Al sheath. The Cu stabilized conductors may also be incorporated into an Al strip by ulstrasonic welding. The Cu may be coated with an intermediate layer of In or Zn, electrolytically or by dipping, to form a low temperature soldered connection between the Cu and Al. When the super-conductor wires can only be produced in limited lengths joints can be made by cold or resistance welding the ends of the lengths of copper-embedded wires together, the resulting conductors being arranged in the final assembly with their joints staggered. A coil may be produced by winding the completed strip round a former, the turns being spaced by distance pieces of a plastics material, or glass-fibre reinforced epoxy resin or indurated fabric which define cooling channels. A steel strip may be wound in parallel with the current carrier to provide extra reinforcement.

[Class 35] In a squirrel-cage or like multi-bar winding, the longitudinal continuity of the bars 11 is interrupted over a part of the cross-section as by slots 12 so as to produce the effect of a multiple resistance section winding for producing desirable starting and running torque characteristics. The ends of the bars are cut away at 14 so that only the lower part of the bars is joined to the end rings 15. In a modification, Fig. 4 (not shown) the slots are arranged along the middle section of the bar leaving an uninterrupted section at the top of the bar of smaller cross-section than the uninterrupted section at the bottom. Thus the effect of three conductors of different resistance is produced.
