Abstract: 1,262,086. Forming multi-layered laps, slitting tubular fabrics. SOUTHALLS (BIRMINGHAM) Ltd. 2 June, 1969 [20 June, 1968], No. 29434/68. Headings D1N and D1S. Multi-layered laps are formed on two conveyors 2, 7 which are positioned close to a carding or web forming machine so that the upper run of a first conveyor receives a web from the carding machine. The second conveyor 7 is positioned beneath the first conveyor and moves at an angle thereto and has means, e.g. pins, for engaging the web between the conveyors so as to wind the web around the first conveyor and to move it to one side thereof in a helical path. A web severing means 9 is positioned at the side of the conveyor to cut off a ribbon of multilayered fibres.

Title: Mesh welding machine
IPC: B23K11/00
Filed: 1969-06-10
Abstract: 1,274,236. Welding by pressure. H. A. SCHLATTER A.G. 10 June, 1969 [24 June, 1968], No. 29449/69. Heading B3R. A machine for welding wire mesh comprises a number of pairs of welding electrodes 2, 3, the upper electrodes being movable from an inoperative to a welding position, a feeding device for longitudinal wires 5 arranged upstream of the electrodes and comprising pairs of vertical clamps 6 which make a feed stroke while the electrodes are open and a return stroke, the jaws clamping the wires 5 at the end of the return stroke when the electrodes are closed and holding means 15 for further longitudinal wires 14 above the feeding device the holding means including wire guides opening into the gaps between the clamps 6. The lower electrode 2 of each pair is fixed to the base 1 and the upper electrode is movable by device 4. The longitudinal wire feeding device comprises pairs of vertically grooved clamping pins 6 with conical tops carried on a slide 7 movable in guide rails 8 by crank-shafts 9 and connecting rods 10. The rails are pivoted to the base at 11 and are tiltable by a lifting means 12 from the position shown, which is adjustable by a device 13, to an upper raised position. Above the feeding device are holders 15 for fresh longitudinal wires 14, each holder having an insert open funnel 17, release means 16 and a stop 18. In operation with the parts in the positions shown the electrodes 3 are lowered on to an inserted cross wire 19 to effect welding, the clamps 6 open and the slides 7 are retracted to the position 7<SP>1</SP>. The clamps then close, the upper electrodes are withdrawn, the lifting means 12 raise the front ends of the rails 8 to lift the wires 5 off the electrodes 2 and the slides 7 make a feeding stroke. The new longitudinal wires 14 are meanwhile fed into the holders 15 and after the wires 5 are exhausted and with the slides 7 retracted the new wires 14 are released to drop into the clamps 6. The part 20 which carries the electrodes and feed devices may be pivoted about a vertical axis so that angled mesh may be produced. The mesh may alternatively be circular with the cross wires radially thereof. This is produced by making the length of the feedstroke on the sides of the slide 7 variable and using a longer stroke on one side than the other. To compensate for shrinkage or to produce curved mesh the lifting means 12 is adjusted by the means 13 so that the clamps press the longitudinal wires below the level of the electrodes 2. The feeding device may comprise a member between the electrodes and clamps, having guide holes for the longitudinal wires.

Abstract: 1,110,419. Ships for liquefied gases; linings. BRIDGESTONE LIQUEFIED PETROLEUM GAS CO. Ltd. 13 July, 1965 [23 July, 1964], No. 29666/65. Headings B7A and B7S. A ship for carrying a liquefied gas, e.g. butane, comprises a framework 6, 7, 8 lodged within an outer hull 4, 5 and supporting an inner hull 10 made of metal plates having a layer 11 of thermally-insulating material, e.g. glass wool, adjacent the outermost sides thereof, the inner hull being a container for the gas and/or a ballasting material. The inner hull may be separated from the framework by wood or other material having poor heat-conducting properties and may be divided into a.plurality of compartments or holds by transverse bulkheads 1 and fore-and-aft bulkheads (2), Fig. 2 (not shown). The gas is delivered to said holds through pipes 17 and discharged therefrom through pipes 15, the latter pipes and an associated pump 16 being also employed to charge the holds with ballasting material. The members 6, 8 at the forward end of the inner hull are situated internally thereof, the other members 6 being optionally in part within the inner hull, Fig. 4 (not shown), so as to minimize the space between the two hulls. A pipe (14) may be provided to detect leakage of gas into the space aforesaid.

Title: Process and apparatus for protecting electric or other cables
IPC: H01B13/14
Filed: 1925-11-25
Abstract: 243,741. Gogry, J. O. Nov. 27, 1924, [Convention date]. Drawings to Specification. Coating wires; impregnating compositions for electric insulation; waterpiroofing; proofing processes and compositions.-Conductors which are covered by unbleached cotton braiding are coated first with a compound heavily charged with a drying oil, such as linseed oil, and containing also gum resin and a pulverulent inert mineral substance such as talc. When dried by exposure to air, a further coating heavily charged with gum and containing paraffin, talc, and traces of linseed oil is applied. The second coating is dried rapidly and glazed by heat. Proofing against the action of moisture and concentrated acids is obtained by adding asphalt to the second coating compound, and applying a further coating containing asphalt, paraffin, petroleum jelly, and talc. The coatings are applied at each stage by drawing the conductor through a bath containing the compounds, and after each immersion drawing it through an apertured plate so as to leave a film of the required thickness. The glazing process consists in passing the conductor with the applied coatings through a plate heated to 100‹ C. or over.

Title: Improvements in and relating to the damping of mechanisms performing limited movements
Inventor: PERCY JOHN NEVILLE BOWNES
IPC: G05G25/00
Filed: 1955-10-19
Abstract: 815,230. Friction brakes. BRITISH BROADCASTING CORPORATION. Sept. 11, 1956 [Oct. 19, 1955], No. 29894/55. Class 103 (1). The invention relates to mechanism, which as shown in Figs. 1 and 2, is applied to operate the turntable 10 of a record player so as to raise a metal disc 13 supporting a sound record 15 away from brake pads 14, of a type which comprises an actuating member 22 adapted to be moved from a first position, in which it is locked to a second position to which it is urged by force-exerting means, for example the spring 19, and in which movement away from the first position is limited by a stop 33. In such mechanism in order to give a positive action, the spring 19 may have to be strong to prevent excessive speed of operation and mechanical shock when the stop is reached, a link 27 is arranged to couple member 22 to a disc 29 frictionally coupled to a flywheel mass 31. Thus, when the actuating mechanism is operated and pivot 23 of link 21 is brought below the axis 24, the link 27 causes rotation of disc 29 and the inertia mass 31 thus has the effect of governing the rate of operation. When the stop 33 comes into action the mass 31 may continue its rotation by reason of its friction coupling with disc 29. The coupling between the member 22 and the disc 29 may be in the form of a cord C, as shown in Fig. 4, and it is shown by calculations that in order to produce a constant angular velocity # of the shaft A, the pulley P 2  should have a spiral profile such that the ratio of radii where T is the uniform torque, I the moment of inertia of the mass, and R the radius of the driving pulley.

As shown in Fig. 1, the tread blocks 3 have the same curvature as the carcass transversely of the tyre but are not curved in the circumferential direction of the tyre. Air remaining in the interior 29 of the tyre may be evacuated through pipes 27, 28. An heat insulating annular plate 12 is positioned adjacent the edges of the bonding plate 2 to control the flow of heat to the bonding plate 2 and also to assist with the removal of air, from under the cover, by means of channels 31, 32 (Fig. 6, not shown) which communicate with passages 13, 14. If a part cover 10 is used, as in Fig. 4b, this is provided with annular beads 16 under which a further cover 17 may be pushed to ensure that the entire tyre is enclosed.
