IPC: D03D35/00
Filed: 1948-11-01
Abstract: 680,895. Shuttleless small ware looms; beat-up machanism; shedding mechanism; fabrics. VOUMARD, B., and NICOLET, W. Nov. 1, 1948 [Nov. 1, 1947], No. 28337/48. Classes 142(i), 142(ii), 142(iii) and 142(iv) In a loom for weaving several ribbons, weft is inserted as single threads and loops of thread alternately, the two limbs of the loops being beaten up individually. Shedding mechanism, Fig. 2. Rods 13a, b divide the warp into two sheets, threaded respectively through heddles 5, 6 which, in the position shown, form a "crossed" shed and, when moved apart, form an "open" shed, the warp sheets then extending direct from the rods 13a, b to the fell. Weft interters, Figs. 2 and 4. When the shed is crossed, weft extending from a supply 4 through a tube 9 to the selvedge is pushed into the shed in loop form by one end 10a of a loop inserter 10; the lower limb of the loop is beaten up by one of a pair of combs 11, 12, .and the upper limb is beaten up by the other comb after the loop inserter has been withdrawn from the shed. The shed then opens and the tube 9 traverses it from right to left to lay a single thread, which is beaten up by one of the combs. On the next (crossed) shed, a loop of weft is inserted (from left to right) by a loop inserter (not shown), the end 10b of the inserter 10 meanwhile pushing weft into the next fabric on the right. The loop inserters may have double ends 10c, d, as shown in Fig. 12, in which case the fabrics are grouped in pairs, the corresponding tubes 9 being staggered so that the end 10c passes through the first fabric of a pair, without engaging its weft, and inserts a loop of weft into the second fabric, the part 10d simultaneously a loop into the first fabric. Beat-up mechanism, Fig. 19. The comb 11 is carried by a frame 15 which is reciprocated horizontally by a cam I, follower 22, and link 23; the frame runs on balls 18, about which it is rocked by a cam II and follower 24 to move the comb 11 vertically. The frame 15 is located sideways by balls 27 bearing on pads 26 on the frame. The beat-up comb 12 is carried by a smaller frame (not shown) arranged within the frame 15 and similarly operated. The cams are such that each comb is lifted a smaller distance before beating up the lower limb of a weft loop than before beating up a single thread or the upper limb of a loop.

Title: Improvements in or relating to the operation of motion picture projectors with alternating current supplies for the light sources
IPC: G03B21/20
Filed: 1939-10-20
Abstract: 535,938. Kinematograph projectors. ASHCRAFT, C. S. Oct. 20, 1939, No. 28353. Convention date, Oct. 21, 1938. [Class 97 (i)] For the reduction of light flicker, alternating current supplied to the light source of a projector has a frequency which is an even multiple of the number of open shutter periods per second, and the shutter alternately intercepts and permits to pass like integral current cycles to provide the illumination ; two projectors having carbon arcs may be connected so as to be alternatively supplied through a frequency converter from supply mains, and so that the arc not in use for projection may be heated when desired by unconverted current taken from the mains. For shutters producing 48 light periods per second, the projection current frequency may be 96, 192 &c., or thereabouts, light flicker being not rendered perceptible by small variations of current frequency. Fig. 5 shows mains 112 supplying current at 60 cycles to a three-phase induction motor 110 having a wound rotor 111 from one phase of which current is alternatively supplied through leads 114, 117, 115, or 114, 24, 27, 115, to parts of the primary windings 118, 28 of transformers supplying arcs 21, 51 through tapped secondary windings 20, 30. The rotor is driven by belt connection from a separate motor, and in a direction opposite to that in which it operates as a motor, at such speed as will produce the desired frequency; switch blades 116, 26, operated simultaneously, control the circuits to the transformers, and switches 122, 52 are provided in the arc circuits. Current may be alternatively supplied to the whole primary windings of the transformers, from one phase of the mains 112, by leads 25, 41, 143, 115, or 25, 31, 33, 115. Switch blades 142, 32 in these circuits, operated simultaneously with the blades 116, 26, ensure that converted current only, and unconverted current only, is supplied respectively and alternatively to the two primary windings, and the switches 122, 52 permit the circuit of the inoperative arc to be closed, for heating of the arc, prior to its being brought into operation. An embodiment of the necessary apparatus, including a relay enabling the blades 116, 142, 26, 32 to be simultaneously operated when the relay switch is closed, is described in the Specification.
