Abstract: 1,269,532. Yarn traversing mechanism. LEESONA CORP. 24 April, 1969 [29 April, 1968; 3 Feb., 1969], No. 20873/69. Heading D1J. In a strand traversing mechanism of the kind comprising a pair of oppositely moving belts 38, 40, Fig. 4, and in which each belt carries one or more yarn guides 26; there is a further yarn guide 10, Fig. 1, exerting a substantially frictionless biasing force on the strand for maintaining a constant yarn tension during movement of the yarn by the guides 26. In Fig. 1 the guide 10 is a pivoted arm 12 causing the yarn to form a U-shaped loop 20 supported on a pressurized cushion of air. This cushion of air also causes the yarn to move inwardly (dotted lines) and outwardly (phantom lines) with the guide to compensate for fluctuations in tension resulting from variations in yarn length primarily due to yarn traverse. The yarn passes over parallel bars 78 between which the yarn guides 26 extend during the major part of their traverse the bars 78 providing resistance to motion of the strand along the strand traversal path. Each yarn guide has a groove 101 therein in which the yarn Y, Fig. 7, is trapped by the bars 78 during the major part of the yarn traverse. Near the end of a traverse movement the belts 38, 40 and therewith the guides 26, move around sprockets 46, 56; 42, 62; Fig. 4, to withdraw a delivering yarn guide 26D, Fig. 7, from between the bars 78 and permit a receiving yarn guide 26R, accepting the yarn, to enter between the bars 78 and traverse the yarn in the opposite direction. To compensate for the increased velocity of traverse that would take place as a guide 26 commences to move around a sprocket near the end of a traverse, the yarn engaging surface of each groove 101 is curved oppositely to its direction of travel near its tip, as at 96 for guide 26D and 98 for guide 26R. The belts 38, 40 are preferably toothed belts and where a yarn guide 26 is secured to a belt the tooth at that location is removed and the yarn guide 26 is secured in position by means that also acts as a tooth on the belt. Fig. 14 shows one method of securing an L-shaped guide 26R or 26D to a belt, the part 126, 127 of the L-shape acting as a belt tooth as well as a face against which the belt is clamped by means of a clamping plate 126', 127'.

Title: Improvements in or relating to oscillator circuits
IPC: H03K3/30
Filed: 1960-07-15
Abstract: 931,164. Pulse oscillator circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 15, 1960 [June 22, 1959], No. 20966/60. Class 40 (6). The invention relates to a blocking oscillator of the type comprising a square loop core transformer 11 having an input winding N1 connected through a switching device (e.g. transistor TR1) to a source of supply E1, for effecting saturation of the core in one sense, a regenerative feedback winding N4 controlling the switching device and a reset winding N2 for resetting the core in the other sense. In accordance with the invention a second coil 17 having a square loop core is connected in series with the switching device, the core being normally biased in one sense (e.g. by winding 18) but being biased towards the other sense when the current exceeds a predetermined value to effect cut-off of the current through the input winding of the first transformer. In the circuit shown, when the core 11 saturates a large current would build up in the input winding but this is prevented because at this point the current brings core 16 out of saturation, producing an e.m.t. in the emitter circuit to initiate blocking of the transistor. Rectifiers D and D1 prevent unwanted pulses occurring. Specification 903,177 is referred to.

Title: Needle bar drive for sewing machines
IPC: D05B55/14
Filed: 1959-06-18
Abstract: 879,300. Sewing machines. SINGER MANUFACTURING CO. June 18, 1959 [June 24, 1958], No. 21004/59. Class 112. In a sewing machine the reciprocating needle bar is turned about its longitudinal axis when leaving the work in order to break the frictional resistance between the needle and the work and thereby reduce the tendency of the work to rise with the needle. As shown, the invention is applied to a zig-zag sewing machine in which the needle bar 7 reciprocates in and pivots about a ball 8. A crank pin 17, carried by the arm shaft 15, is connected by a link 18 to a pin 21 which projects from a yoke 22 pivoted to the needle bar about an axis perpendicular to the plane in which the needle bar oscillates. Pin 21 is slidable in a bearing sleeve 19, on link 18, inclined to the axis of shaft 15, when pin 17 is at its dead-centre positions, at an angle of 8 degrees. Owing to the arrangement the needle bar turns about its axis, the rate of turning being greatest at the top and bottom positions, but the turning then occurring in opposite directions. The arrangement also compensates for the vertical variations of the needle eye relatively to the beak 5 of the vertical axis looptaker 4 during zig zag stitching. Beak 5 and the needle eye are arranged at their optimum relative positions when needle eye is in its central position 23. Pin 21 slides in sleeve 19 to raise the needle eye to an extreme right hand position 23a, and to lower the needle eye to an extreme left hand position 23b, so as to compensate for the respective earlier and later loop-seizing moments corresponding to said positions. Specification 808,351 is referred to.

Abstract: 761,616. Pneumatic conveyers. SIMON HANDLING ENGINEERS, Ltd. May 16, 1955 [July 26, 1954], No. 21713/54. Class 78 (1). In an automatic tipper a of the oscillating type for discharging material at the end of a pneumatic conveyer, the shaft c, about which the tipper oscillates, carries freely at each end a pair of levers g, each pair on the same side being connected by a cross-member h which carries a counterweight i and is connected by springs o to the adjacent tipper door m or n. A bracket j on each lever g carries a roller k which bears on a door. The tipper is oscillated by reciprocating rods r, each of which passes through a block s pivoted on the end of a rod t secured in the tipper below its pivotal axis. Compression coil springs u are mounted around the rod between collars v and the blocks s. Stops p limit the downward movement of the levers. When the tipper has been moved clockwise to 'the position shown in Fig. 1, the springs o have been tensioned sufficiently to pull open the door n and hold it against the rollers k. When the movement of the rods r reverses, the adjacent compartment is moved towards the door n and reduces gradually the tension of the springs. When the door engages the compartment, the levers g are lifted and the weight i keeps the door closed firmly.
