Title: Racking means for knitting machine
IPC: D04B9/06
Filed: 1956-06-27
Abstract: 820,218. Knitting-machines. WILDMAN JACQUARD CO. June 27, 1956, No. 19870/56. Class 74 (2). The butts on the cylinder needles when passing up the face of a transfer cam of a cylinder and dial machine engage a member which causes actuation of mechanism which racks the dial relatively to the cylinder. After selection of a cylinder needle or needles the butts of the selected needles are engaged by the transfer cam and in moving up the cam face come into contact with earn 111, Fig. 5, attached to a post 107. The cam 111 and post 107 are thereby raised by the butts and release a slide 100 which is projected by a spring 103 into engagement with a ring 89. The slide 100 rotates with the cam cylinder and its outer end is serrated to engage corresponding serrations 93 on the ring 89, Fig. 4, thus carrying the ring 89 round with it so that a projection 92 secured to the ring engages an arm 79. The arm 79 is integral with a second arm 78 also serrated at its outer end and which arms are keyed to a sleeve 74 around a continuously rotating shaft 51. The shaft 51 is geared at its upper end to a clutch 46, 47 the normally stationary part 47 of which is released by an arm 75 when the sleeve is rotated. The part 47 is keyed to a shaft 48 carrying at its upper end a part 61, 62 of a Geneva stop mechanism, the other part including the star wheel 63 being mounted on a stationary part 54 of the machine. The shaft 64 for the star wheel also carries a plate 68 having a cam groove engaged by a follower 72 which transmits the motion imposed by the cam groove to the dial of the machine through dogless mechanism similar to that described in Specifications 364,616 and 365,031 so as to rack the dial in one direction or the other. Rotation of the shaft 48 also rotates a cam plate 131 secured to its lower end such that a follower 136 in its groove causes the arm 75 to move further in the direction in which it has already been moved by the engagement of arm 79 by pin 92. The effect of this is to cause the serrated end of arm 78 to engage serrations 99 on a ring 90, normally rotating with the cam cylinder, and prevent its rotation such that as a result of the relative motion between the ring 90 and slide 100 a pin 102 on the slide engages a slope 97 in the ring to withdraw the slide to be latched by post 107 and release the ring 89. Further continued movement of the arm 75 by cam plate 131 moves the arms 78 and 79 and ring 89 back to their initial position, the ring 90 also being disengaged from arm 78 is returned by a spring 94 to its initial position. The slide 100 is further controlled by a cam 119 under pattern control means 122 so that post 107 and cam 111 may be raised without releasing slide 101.

Title: Improvements in or relating to electric protective arrangements for sectionalised a.c. circuits
IPC: H02H3/30
Filed: 1945-08-08
Abstract: 598,581. Protective cut-out systems. REYROLLE & CO., Ltd., A., LEYBURN, H., LACKEY, C. H., and TOWNS, D. H. Aug. 8, 1945, No. 20337. [Class 38(v)] A protective arrangement for a sectionalised A.C. circuit comprises at each end of the protected section, a transmitter F acting on fault to send to the remote end of the section a h.f. current modulated in accordance with the secondary output of a saturable transformer D, whose primary is fed from line current transformers B1- B3, and a receiver K for demodulating the h.f. current from the remote end, tripping means being responsive to the phaserelationship between the outputs of the receiver and the saturable transformer for cutting out the section at the adjacent end the section preferably being cut out at both ends on an internal fault whether it is fed from one or both ends. The secondary winding D1 of the saturable summation transformer D is connected through a filter E, which provides a uniform standard wave form, to a h.f. transmitter F set in operation by a further winding D2 of transformer D, so as to feed modulated h.f. current into the section through coupling condensers H and a filter L, which also prevents this current from reaching the adjacent receiver K. The latter receives the modulated h.f. sent from the far end, demodulates it, and passes the output through a saturable filter M to a comparison circuit in which it is compared with the output of the adjacent transformer D in series in the grid circuit of a valve N. On an external fault, the outputs from the secondary D1 and the receiver K are in phase-opposition so that the grid of valve N remains negatively biased. With an internal fault fed from both ends, however, the two outputs are additive and the anode current of the valve receives an A.C. component which energises the tripping relay P through a transformer O. With an internal fault fed from one end only, the grid of one valve N receives only the transformer output, and the other grid receives only the transmitted output, but each output is arranged to be sufficient to produce tripping at that end. In modifications, Figs. 2-4 (not shown), the outputs are applied to the relay P via circulating- current or opposed-voltage circuits, or fed into two balanced windings of the relay or of a transformer energising the relay.

Filed: 1943-12-06
Abstract: 604,427. Cathode-ray oscillographs.. STANDARD TELEPHONES & CABLES, Ltd. Dec. 6, 1943, No. 20395. Convention date, Dec. 5, 1942. [Class 37] [Also in Group XL (c)] A series of impulses of predetermined spacing are produced by applying an initial impulse to a delay device, e.g. an artificial line, and taking off the desired impulses at selected points thereon and at a desired amplitude. The system is designed for providing the coarser calibration marks on the screen of a cathoderay tube, the finer intermediate marks being provided by causing the initial pulse to shock excite a tuned circuit. Means are also provided for selecting a suitable location of the scale of a vernier tube relatively to the main tube. The initial signal 12, Fig. 1, is applied to shock excite an oscillatory circuit 14 as in Specification 592,582, [Group XL], to produce a train of waves 20, Fig. 2, which are limited and differentiated to produce pulses 24. These are applied to the grid of a valve 30 to give sharp marker pulses which are fed at 38 to the deflecting plates of a cathode-ray oscillograph, thus producing on the screen the finer graduations 24a, Fig. 2. The initial pulse 12 is also applied to a delay network 44, 45 as in Specification 592,617, [Group XL], with a series of tappings each earthed through a potentiometer 46, the adjustable members of which are all connected in parallel to a second control grid 50 of the valve 30. The delay between tappings corresponds to a multiple, say 5, of the spacing between pulses 24a, so that the coarser marks 61a, 62a, &c. may appear on the oscillograph screen. Alternate pulses of this series may be given a larger amplitude, by adjustment of the potentiometers. A timing pulse 85 for a second vernier oscillograph is provided by a switch 80 co-operating with contacts 71 connected to the several taps on the line 44, 45. This switch is adjusted by hand, and applies a pulse at the selected moment to a grid of a second valve 30a, the other grid of which received the pulses 24. When the input pulses are simultaneous, an output pulse is taken. from the anode to synchronize the time base of the vernier oscillograph, and to provide a reference mark on the main oscillograph. Specification 592,574 also is referred to.
