Title: Improvements in or relating to circuit arrangements for controlling gas- or vapour-filled discharge tubes
IPC: H01J17/04
Filed: 1955-02-11
Abstract: 779,024. Rectifying. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 11, 1955 [Feb. 13, 1954], No. 4152/55. Class 38 (2). The instant of ignition of a gas- or vapourfilled valve 8 through which a load 9 is supplied with D.C. from a source of A.C. 10, is controlled by varying its grid-cathode voltage which is the sum of an alternating voltage from transformer 7 and the voltage drop across resistor 5 which is in the anode-cathode circuit of a hard valve 1 in series with a battery 6. Conductivity of valve 1 is controlled by variation, e.g. by a high-speed circuit breaker, of the unidirectional voltage of source 4 which is connected in series opposition to a battery 2 and in series with a source 3 of alternating voltage. With zero voltage of source 4, valve 1 carries saturation anode current and the consequent voltage drop a, b, c, d, Fig. 4, added to voltage 22 of source 7 gives a resultant cathode voltage 23 to valve 8 which, being less than the required value 20 does not fire valve 8. When voltage 4 increases, the voltage across resistor 5 becomes e, f, g, h, Fig. 5, and the resultant grid voltage 24 rises above valve 20 at point 25 to fire valve 8 at instant 26 in the positive halves of the anodecathode voltage wave 16. As voltage 4 increases, the instant of firing advances. The trailing edge of the firing peak follows closely the voltage 22 which leads the anode-cathode voltage 16 by 30 degrees so that when the latter reverses the grid of valve 8 is negative and danger of back fire is reduced. Voltage from source 3 leads voltage 22 from source 7 by 45 degrees. In a three-phase circuit, Figs. 7, 9 (not shown), the danger of back firing before ignition of the incoming phase may be reduced by arranging an R.C. circuit in the grid circuit of valve 8, Fig. 8 (not shown), whereby the phase of voltage 22 is altered and a negative direct voltage is added to it.

Abstract: 490,527. Electromagnetic switches. FERRANTI, Ltd., NORRIS, E. D. T., and NEWTON, N. Feb. 12, 1937, No. 4177. [Class 38 (v)] [Also in Group XXXV] Fig. 1 shows a relay, which may be of the kind described in Specification 465,058 and comprises earthing coils k, m in the respective circuits controlled by the relay contacts. To prevent the resetting action from moving the switch a beyond its mean position, a catch plate p has notches s, t co-operating with a tongue q rigidly attached to the relay arm e, and an electromagnet x brings a tongue. u into the path of the tongue q each time a relay circuit is closed. A dashpot z delays the withdrawal of the tongue u by gravity. In a modification, a tongue 9, Fig. 4, on the relay arm e lies between the poles of an electromagnet 10 when the relay is in its mean position, the magnet being energized as in the previous arrangement. In a further form, Fig. 5, three mutually rigid vanes 13, 14, 15 are pivoted at 26 to the relay arm e. The vane 15 is weighted and lies in an oil bath. The remaining vanes frictionally engage a fixed plate 12 when resetting occurs.

Abstract: 932,450. Key locks. FISHER & LUDLOW Ltd. Feb. 6, 1960 [Feb. 6, 1959], No. 4182/59. Class 44. A coin vending machine of the kind in which the body of the machine is constituted by two interfitting cases 10. 11 between which the operating mechanism, the magazine for the articles which are to be delivered by the machine and the money which has been inserted into the machine are housed, has the inner case 10 formed with a recess 16 adapted to secure the body 12 of a lock, the body being a close fit in the recess and secured to the outer case 11. As shown the body of the lock is fastened to the inside of the wall of the outer case 11 with a barrel 20 projecting through an aperture in the outer case. One wall of the recess is formed with a slot 18 which acts as a keeper for the bolt 19 of the lock. The recess prevents the barrel 20 being disengaged from the aperture if the fastenings 14 securing the lock to the case 11 are tampered with and so prevents separation of the inner and outer cases.

Title: Improvements in or relating to television and like apparatus
IPC: H04N3/08
Filed: 1930-02-07
Abstract: 348,638. Television. BAIRD, J. L. and TELEVISION, Ltd., 133, Long Acre, London. Feb. 7, 1930, Nos. 4225/30 and 11353/31. Divided on 348,638. [Class 40 (iii).] Relates to systems in which the picture is scanned in bands which are narrower at some parts of the picture than at others. The widths of the bands may be progressively changed. A mirror drum 10, Fig. 2, has a series of plane mirrors of which at least one mirror 12, replacing a normally positioned mirror at 22 scanning a band 24, has its inclination altered to scan a wider band 26 and is displaced to a position 28 so that the band 26 is positioned at substantially the position of the band 24. Alternatively, the mirrors scanning the wider bands may be curved mirrors, so that divergent beams of light are produced. If all the mirrors are curved, some may have a greater curvature than others. At the transmitter where plane mirrors are used the mirrors may be canted so as to scan in substantially equal separated bands so that the mean illumination of the cell may be constant. The degree of separation will correspond to the degree of widening of the bands at the receiver. If cylindrical mirrors are employed at the transmitter the bands may be contiguous since the total brightness remains the same, independent of the width of the band. When cylindrical mirrors are employed at the receiver, their width may be increased so that the intrinsic brightness of the wider bands shall not differ from that of the narrower bands. Where the exploring device comprises a lens disc, some of the lenses may be cylindrical so as to enlarge one dimension of the scanning beam ; such lenses may require a displacement to prevent overlapping of the bands. If a drum or truncated cone is apertured, the holes 70, Fig. 8, may be displaced to prevent overlapping and the band widened by the use of a prism 72. The prism or prisms may alternatively be mounted on the screen 76, Fig. 9, and may be of different angles to widen the scanning bands to different degrees. The prisms may be used with any light-transmitting device in place of the aperture and may have their faces slightly ground. Where mirror drums are used a lens 16, Fig. 2, is located between the drum and an aperture 20 behind which is the cell 18. By placing the lens at its focal length from the mirrors the size of the aperture may remain constant for all positions of the object although it is necessary to adjust its position according to the position of the object. Specification 303,771, [Class 40 (iii), Telegraphs, Electric], is referred to.

Filed: 1953-02-16
Abstract: 740,631. Fluid-actuated valves. PRENDERGAST, C. S., and GORDON, H. Dec. 16, 1953 [Feb. 16, 1953], No. 4264/1953. Class 135. A valve for controlling the spill of surplus fluid from a liquid system has a controlled pressure chamber X with an inlet 1B from the system and a spill outlet 3C; the effective area of which can be adjusted by a manually settable member 6, the controlled pressure chamber being bounded by two interconnected pistons 2, 4 of different diameters and the smaller piston 2 operating to shut off the inlet in opposition, to a spring 12 acting on the larger piston 4. The inlet is formed as a transverse bore 1B extending diametrically through a bore 1A for the piston 2 in a body part 1 and being connected at its ends to the system. The member 6 consists of a throttle adjusted by a screwed spindle 6A. The larger piston 4 which operates in a bore 3A in a body part 3 has a bifurcated extension 4A connected by a cross pin 5 to the rod of the smaller piston 2. A perforated baffle 13 is arranged at the junction of the bores 1A, 3A to prevent pressure fluctuations due to high-velocity flow into the controlled pressure chamber. The body parts 1, 3 are closed by end caps 10, 11 with recesses 10A, 11A connecting the bores 1A, 3A by ducts 1D, 3D with the spill outlet 3C. The arrangement shown ensures a constant spill from the pressure system for given position of the throttle 6 irrespective of the pressure in the system. In a modification however the smaller diameter piston has a stepped part against which the pressure in the system acts so as partly to offset the effect of the loading spring. In this case the rate of spill decreases as the pressure in the system increases so that hydraulic slip in other parts of system may be compensated.
