Title: Electrical apparatus for controlling electrode potentials
IPC: H01J31/12
Filed: 1971-02-08
Abstract: 1385892 Cathode-ray display tubes UNITED KINGDOM ATOMIC ENERGY AUTHORITY 8 May 1972 [8 Feb 1971] 4209/71 Heading H1D The potential of an isolated deflection electrode in a vacuum chamber relative to an adjacent electrode is controlled by providing on one of the electrodes a photo-emissive surface which is illuminated by an adjustable source. Fig. 1 shows a section of a flat cathode-ray display tube wherein an electron beam 13 travelling normal to the plane of the drawing is deflected by one of a number of parallel strips 15 to a fluorescent screen 12. Opposite the strips 15 is a photo-emissive electrode 16 at a high negative potential (- 10 kv.) and adapted to be illuminated by a light emitting diode 17 supplied from a source 24 via an operational amplifier 23. A capacitive pick-off electrode 22 senses the rate of change of potential of the electrodes 15 and provides a feedback to amplifier 23 to keep the rate constant. When electrode 15 falls to the potential of electrode 16 the output from pick-off 22 ceases and the resultant rise in the output of amplifier 23 may be used to switch on a supply of current to the next diode 17 controlling the next electrode 15. Successive reduction in the potentials of electrodes 15 produces frame scanning normal to the plane of Fig. 1, after which the electrodes are restored to the potential of electrode 18 by illuminating photo-emissive surfaces 19 on the electrodes with a source 21, e.g. a gas-discharge lamp. Line scanning employs a row of deflection plates (14, Fig. 2, not shown) which may each be connected to positive and to negative electrodes via silicon junction photodiodes so that the scanning may be achieved by controlled illumination of the diodes. In a modified feedback circuit (Fig. 3, not shown) the pick-off electrode 22 is connected to an operational amplifier provided with resistive feedback. This produces a square wave output of amplitude proportional to the rate of rise of potential of electrode 15, and this output is rectified and used to control the supply 24 driving the electroluminescent diode.

Title: Improvements relating to the Insertion and Beating-up of the Weft in Looms for Weaving.
IPC: D03D49/62
Filed: 1917-03-27
Abstract: 105,237. Schwarzenbach & Co., R. Jan. 7, 1916, [Convention date]. Beat-up motions; reeds.--In a loom especially adapted for weaving fabrics of silk or other fine materials, the weft is beaten up by a rotary open reed with teeth held yieldingly in position near their free ends, the continuously-rotating shaft of the reed being carried by oscillating supports and so actuated that its normal speed of rotation is accelerated during the beating-up of the weft and retarded on the return oscillation of its supports, while a bar is raised to spread the warps just before the reed engages them. As shown, open reeds 3, 3<1>, Figs. 1 and 2, are secured to a rotary shaft 4 mounted in supports 5, which are pivoted on a shaft 6 and are oscillated by pitmen 7 from the crank-shaft. The shaft 4 is rotated half a revolution for each revolution of the crank-shaft by a worm 20 and a worm-wheel 19 on a shaft 18, which is disposed at the side of one of the supports 5 and rotated by bevel-wheels 17', 16, 15 from a shaft 12 connected by gearing to the crank-shaft. The bevel-wheel 16 is rotated in the direction of the arrow, so that, as the supports 5 are oscillated forwards for the beat-up, the rotation of the shaft 4 is accelerated, and, during the return oscillation, its rotation is retarded so that the reed teeth are drawn down from between the warps 24, 25 without damaging the weft. Just before the beat-up, the warps are raised and spread, as shown in Fig 2, for the entry between them of the reed teeth, by a bar 27 which is oscillated by a rod 28, a pivoted piece 30, a rod 31, and a lever 33 actuated by a cam 35 on the shaft 6, to which the bevel-wheel 16 is secured. The teeth of the reeds 3, 3' pass through and are soldered or otherwise secured to the coils of springs 21, and pass yieldingly through the coils of springs 22, which are traversed by half-round rods 26 to hold the teeth in alinement, so that the teath may spread out to allow thick parts of the warps to pass between them. The backs of the free ends of the teeth are rounded off as shown, to ensure easy entry of the teeth between the warps and rapid release therefrom. The lay beam 1 is stationary and has mounted in it a closed reed 2, which is gradually moved to and fro longitudinally to give transverse movements to the warps, by an arm 40, Fig. 4, having an eye engaged by an eccentric 39 on a shaft rotated intermittently by a ratchet-wheel 37 and a pawl 42 on a lever 41 oscillated by a cam-actuated rod 43.

Filed: 1969-01-27
Abstract: 1,204,084. Coiling helices. HANS SICKINGER CO. 27 Jan., 1969 [26 Jan., 1968; 6 Dec., 1968], No. 4480/69, Heading B3E. A wire coiling tool 11 for forming helical wire binders comprises a rotatable mandrel 15, and a stationary body 18 surrounding and spaced from the mandrel and having a plurality of circumferentially spaced sets of pins 28 and 29 extending inwardly towards the mandrel with their inner ends closely adjacent the mandrel 15, the pin sets being in rows which extend axially with respect to the mandrel. The mandrel guide portion 17 is disposed within a forming body comprising two element halves 19 and 21 with top and bottom portions cut away by parallel planes. The pins of each set are successively shorter in the direction towards the outer end of the mandrel. Their end surfaces are shaped so as to be complementary to the flared and curved surface of the mandrel guide portion 17 and are closely adjacent the surface of the mandrel. A tapered space 33 is formed in element 21 at the juncture of abutting surfaces 32 with the open portion of element 21. The wire is fed in at the opening 33 and then manually threaded back and forth between adjacent pins 28 and 29. Another recessed portion 34 is formed at the outer end of element 19 to accommodate a wire cutting knife 35. In operation the mandrel 15 is rotated, thus frictionally driving the wire between the sets of pins 28 and 29 which guide the wire so as to form a helix which is fed out at the right hand end of the tool. In another embodiment two sets of guide pins 116 and 117 are carried by element 105 and two sets of guide pins 118 and 119 are also carried by element 106 so that each set is spaced 90 degrees apart.

Abstract: 938,847. Forcing liquids by gaseous pressure. UNION TANK CAR CO. Feb. 6, 1962 [Oct. 16, 1961], No. 4585/62. Class 102(2). Apparatus for handling liquid material comprises a pair of vessels 10, 12 having vents 26 to atmosphere and conduits 28 supplying pressurised fluid for emptying the tanks, and valve means 24, 25 for the vessels 10, 12 respectively disposed in the respective conduits and vents. Material flows into the tanks, through inlets 14, until the level reaches either of the sensing elements 30, 32, whereupon a first electric circuit energizing coil 42 is completed should the liquid level reach element 30. The first circuit comprises contact 78, pole 106, rectifier 80, coil 42, element 30 and earth point 38. When coil 42 is energized a timer 48 is energized through switches 44, 46 which energizes a solenoid 56 shifting the valve 24 to allow pressure fluid to enter the vessel 10. As the material clears the element 30, the circuit which initially energized the coil 42 is broken, but a holding circuit maintains the coil energized. The holding circuit comprises contact 78, pole 106, rectifier 80, coil 42, contact 92, pole 102, line 168 and contact 76. When the vessel 10 is empty the timer 48 operates the switches 52, 54 to break the holding circuit. Under normal conditions, since the circuit for coil 42 or 60 of one vessel passes through a coil operated switch of the other vessel only one coil can be energized at a time to prevent both vessels being emptied simultaneously. In the event of vessel 10 becoming fouled and contact between the element 30 and earth being maintained after the timer has broken the holding circuit, when the vessel 12 is filled, coil 60 is energized and coil 42 de-energized. Should the element 32 also become fouled and remain earthed, an energizing circuit for coil 42 is established on closing the switch 70 at the end of ejection of the vessel 12. This process continues, one vessel ejecting immediately after the other, until the fouling is removed.
