Title: Improvements in or relating to circular looms
IPC: D03D37/00
Filed: 1933-07-21
Abstract: 422,861. Circular looms. BRITISH CELANESE, Ltd., 22, Hanover Square, London, POOL, W., c/o British Celanese, Ltd., Spondon, near Derby, and DREYFUS, H., 22, Hanover Square, London. July 21, 1933, No. 20585. [Classes 142 (ii) and 142 (iii)] A circular loom employing one or more weft-spool-carrying shuttles is provided with means for replenishing each shuttle with weft, on exhaustion of the spool, in the course of the normal operation of the loom such replenishment being effected at one or more gaps provided in the cylindrically arranged warp threads. Each shuttle 19 is provided with a rotatably mounted spool 41 operatively connected with a train of gears 45 the leading pinion 44 of which projects from the body of the shuttle into the path of a segment shaped rack 42 located at a gap A in the warp threads 10. When the shuttle emerges from the warp threads, weft yarn 35, extending from a guide 40 to a point adjacent the fell of the fabric, is engaged by the spirally slotted inner flange 47 of the spool and, during subsequent engagement of the pinion 44 with the rack 42 in the passage of the shuttle across the gap, a length of weft is withdrawn from a stationary package 36 and wound on the spool 41. On re-entry of the shuttle into the warps, a cam 52 on the rack 42 rocks a pivoted lever 54 on the shuttle and thereby raises and lowers a pivoted arm 58 which engages and moves to the fell of the fabric, the weft extending from the spool to the guide 40. The downward movement of the arm 58 brings the weft into a spring tension device 64 carried thereby and into a guide slot 62 on the shuttle. As the shuttle passes within the warps, a cam 65, Fig. 7 on a rotating cam ring 66 engages a relatively stationary plunger 67 and oscillates a finger 70 so as to depress the weft below the fell of the fabric and into engagement with a toothed weft cutter 74. Subsequent operation of the latter by the cam 65 severs the weft from the supply. The length of weft extending from the cutter 74 to the guide 40 is wound on an auxiliary spool 50 during subsequent replenishment of the same or a following shuttle. The length of weft laid in the fabric is maintained under tension during unwinding by the resistance of the train of gears 45 and the tension device 64. The shedding of the warps is effected by pivoted levers 16 which are rocked by the action of a rotating cam ring 27 on their arms 24. Specifications 396,757 and 413,376 are referred to.

Abstract: 1,013,315. Welding by pressure; coiling; making gilled tubes. BROWN FINTUBE CO. May 19, 1964 [June 6, 1963], No. 20590/64. Headings B3A, B3E and B3R. A helical fin is welded to a cylindrical member T, e.g. a tube or bar by rotating and advancing the member, pressing an edge of a strip S against the member T at the weld zone, passing current between electrodes contacting the member T and the strip S to weld the edge of the strip S to the member T and supporting the member T against the welding pressure exerted by the strip S by a device engaging the welded strip S. High-frequency welding current of at least 50,000 cycles per second is used together with a welding pressure sufficient to deform and thicken the strip S adjacent the weld. A tube T is rotated and advanced by three pairs of skew rolls 13 . . . 15 rotated by shafts 52 driven by a  motor 5 through a clutch 4. Each roll is knurled and tapered towards the other roll of the pair. The axis of rotation of each pair of rolls is angularly adjustable and the upper pair 15 is vertically adjustable. The rolls are interchangeable with other sets of different size and the frame 11 supporting the rolls is mounted on a base 1 by an interchangeable spacer block 12. The welding pressure is taken by a supporting roll 101 engaging several turns of the welded strip and mounted on a bracket 103 vertically adjustable on a bracket 104 angularly movable about a pivot 67 attached to the base 1. The welding unit is mounted on a plate 64 attached to the base 1 by the pivot 67 whose axis passes through the weld point W. Welding pressure is applied to the strip S by a deeply grooved copper alloy roller 95 carried on an arm 91 pivoted on a support 88 adjustably secured to the plate 64. An air cylinder 93 provides the welding pressure. Strip S, the leading end of which is spot welded to the tube T or to the trailing end of the welded fin F is drawn through a guide 145 attached to a frame 71b supported on the plate 64 by a pedestal 71 including an interchangeable spacing member 71c. Welding current is supplied through bars 105, 106 depending from a transformer 8 adjustably secured in guideways 73 on the frame 71b. An electrode 76 is pressed against the side of the strip S by an air cylinder 132 acting on an electrode holder 128 slidable in guides 129, 130 on a block 126 fixed to the bar 106. An electrode 75 transversely adjustable in a dovetail mounting 117 on a member 113 is pressed against the tube T by an air cylinder 119 acting on the member 113 which is slidably mounted on a block 111 depending from the bar 105. The various electrode mounting members are liquid cooled and water is sprayed on to the tube T and fin F adjacent the weld zone. The strip S is fed through a guide aperture 143 formed in insulating members 136, 138 secured to the blocks 111 and 126. An interchangeable adaptor 144 is fixed in the aperture 143.

Title: Improvements in Saw Sharpening Machines.
IPC: B23D63/12
Filed: 1918-12-11
Abstract: 136,604. Dwyer, D. A., and British Saw Sharpening Machines, Ltd. Dec. 11, 1918. Saws, sharpening.-Relates to a saw-sharpening machine of the type described in Specification 13008/15, and comprises the use of modified mechanism for performing the operations of lifting and lowering the grinding-wheel, for producing the bevel-cut, and for feeding the saw to give the required shape and pitch to the teeth. The machine is driven by a shaft 3 through a twospeed gear-box 2, and the various movements are produced by the rotation of the shaft 4 carrying an eccentrically-mounted disk 5, to which is adjustably connected, to give a variable stroke; one end of a rod 6 connected at its other end to an oscillating arm 7. This arm is mounted on a shaft 8 carrying a cam-disk 9 having thereon an arcuate attachment 9a pivoted at 9<b> to the disk and adjustable, to alter the working face, by means of a screw 9<d>. The working face of the arcuate piece contacts with a roller 10<a> mounted on a lever 10 pivoted at 10<b> to the support 11 and contacting with a roller 12<a> mounted on a block 12 carried by and adjustable by means of a screw 13<b> with reference to the grinding-wheel head 13, which is slidable in the support. The saw is fed forward by means of a pawl 18<a> engaging the teeth thereof and actuated, through levers 16, 17, 18, by a roller attached to the cam-disk 9 and adapted to contact with an adjustable former 15<a> mounted on the lever 16. The bevel or angular motion of the grinding-wheel 14 about the spindle 13a is given, through a projecting arm 26 on the spindle and a connecting-rod 22, by a forked lever 20 pivoted at 20a to the grinding-wheel head and having frictionally secured to each of its upper arms a notched plate 20<b>. As the head rises, these plates alternately engage the projecting lower points 21a of a pendulum 21, thereby swing- ing the forked lever. The pendulum is secured to a pivot 21b adjustably mounted in a bracket 11<a>, and is normally held central by springs 21<c>. To adjust the extent of the angular movement, the arm 26 carries a quadrant having at each end an adjustable stop adapted to contact with a projection 25 secured to the fixed part of the head, thereby limiting the movement of the arm. The springs 21<c> and the frictional contact of the blocks 20b with the forked lever provide means for the prevention of injury to the machine.

Abstract: 1426159 Uranium dioxide compositions GENERAL ELECTRIC CO 14 May 1974 [10 Aug 1973] 21385/74 Heading C1A A uranium dioxide-rich composition is prepared from uranium hexafluoride in a reaction zone in the presence of an active flame by: (a) introducing into the rection zone a gaseous mixture of uranium hexafluoride and a reducing carrier gas (b) separately introducing an oxygencontaining gas and (c) separately introducing between (a) and (b), a shielding gas which temporarily prevents substantial mixing and reaction between (a) and (b) until sufficient cross diffusion of (a) and (b) with the shielding gas occurs as they pass through the reaction zone. The reaction may be initiated by introducing (a) reducing carrier gas (b) shielding gas (c) oxygen-containing gas and (d) uranium hexafluoride in sequential steps into the reaction zone (optionally the reducing carrier gas and uranium hexafluoride may be introduced simultaneously). The reaction may also be initiated by introducing (a) oxygen-containing gas (b) shielding gas (c) reducing carrier gas and (d) uranium hexafluoride in sequential steps into the reaction zone. The reaction zone may be purged with inert gas before the gaseous reactants are introduced. The mixture of uranium hexafluoride and reducing carrier gas may be introduced into the reaction zone as a plurality of individual adjacent streams each surrounded by shielding gas. The reducing carrier gas may be hydrogen, dissociated ammonia or a mixture thereof or the above mixed with an inert gas. The oxygen-containing gas may be oxygen, air or a mixture thereof. The shielding gas may be hydrogen, dissociated ammonia, an inert gas or a mixture thereof. The molar ratio of the reducing carrier gas to uranium hexafluoride may be at least 4À0 and that of oxygen to uranium hexafluoride at least 1À2. The reaction may occur in a flame of at least 750 C. The reaction zone may be preheated to at least 100 C. The reaction zone may be maintained under a reduced pressure of 1-25 inches of mercury to draw the reaction products from the reaction gas and the gas stream withdrawn may be treated to collect hydrogen fluoride and water vapour in the form of hydrofluoric acid. The uranium dioxide formed by the above method may be converted to a higher oxide of uranium by converting the residual reducing gas in the reaction zone into an oxidized form.
