Title: Improvements in fluid pressure control valves
IPC: F15B13/02
Filed: 1962-08-02
Abstract: 951,528. Valves. HYDRAULIC UNIT SPECIALTIES CO. Aug. 2, 1962 [May 2, 1962], No. 29755/62. Heading F2V. [Also in Division G3] A fluid pressure control valve has a body 5, Fig. 1, with a valve element 12, Figs. 1 and 3, movable therein to each of a pair of positions to communicate in the body either of a pair of service passages 13, 14 with a fluid supply passage 18, 23, 24 and to communicate the other service passage with a return passage 29, 22, a void control passage 34 for directly connecting the return and supply passages and a check valve 37 to open the passage 34 when the return passage pressure exceeds that of the supply passage. In the preferred embodiment, two elements 12 are slidably mounted in body sections 8, 9 assembled in stacked relationship with further sections 6, 7 so that fluid can flow from passage 18 to a passage 20 by way of an open centre passage 21 extending through all of the sections when the elements 12 are in their neutral positions. When one of the spools is moved to an operating position, it blocks the passage 21 and directs fluid from a feeder passage 23 to one of the service passages 13, 14, the other service passage being simultaneously connected through a branched passage 30 with the return passage 29. A valve 47 has a forwardly facing surface 96 which causes it to open against a spring when the pressure in the passage 20 is greater than that in the passage 20 and an adjustably spring- loaded pilot valve 97 that is depressed by a plunger 101 to open a vent 100 when the pressure in passage 29 exceeds a predetermined value. The opening of the vent 100 permits the valve 47 to open and partial obstruction of the intersection of bores 94, 99 by the plunger prevents chattering. A restricted orifice may be used in place of the valve 47. The check valve 37 may be gravity or spring-loaded and in a modification consists of a hollow spring-loaded single beat lift valve providing a seat for a separately spring-loaded single beat lift to replacing a pressure relief valve 36 in the embodiment shown. Specification 950,131 is referred to.

Title: Improvements in or relating to electronic counters
IPC: H03K23/82
Filed: 1949-11-22
Abstract: 664,895. Electronic counting apparatus. BRITISH TABULATING MACHINE CO., Ltd. Nov. 22, 1949 [Dec. 1, 1948], No. 29882/49. Class 106 (i). In a high-speed electronic counter comprising chain-connected trigger circuits each comprising two cross - coupled plural - grid tubes alternately conductive in response to pulses received, and a gridcontrolled tube E1 operatively connected between the first and second trigger circuits A and B, a tube G1 is interposed between tube E1 and a higher trigger circuit for rendering the tube E1 operative to determine the stable condition of a trigger circuit higher than B during part of the counting cycle. The decade counter shown comprises four triggers A, B, C, D of which tubes A2-D2 are conductive in the zero or " off " condition obtained by opening switch CBS. Negative pulses to be counted are sent from terminal 40 to the plates of trigger A and, when two pulses have been received, trigger A is switched to the " off " condition and the increased plate voltage of tube Al is applied to the control grid of 39 tube E which then conducts and sends a negative pulse from its plate 46 through capacitor 43 to the plates of trigger B. A negative pulse is similarly applied to the control grids of tubes C1, C2 over line 71 from the plate circuit of another gridcontrolled tube F1, whenever trigger B is switched off. On receipt of an eighth pulse, trigger C is switched off, and a negative pulse over line 74 from the plate of tube C2 to the control grid of tube D2 switches on trigger D. The increased plate voltage of tube D2 is applied over line 78 to the control grid 57 of tube G1 which then conducts, thus reducing the plate voltage of tube E1. Thus the positive voltage applied to grid 39 on receipt of the tenth pulse, while not causing an effective negative pulse to be applied from plate 46 to trigger B, causes conduction through the screen grid 49 so that a negative pulse is sent over lead 51 to the control grid of tube D1, thus switching off trigger D, whereupon a negative pulse is sent to output terminal 76, and to grid 57 to cut off tube G1. The latter operation is, however, delayed by the increased plate voltage of tube D1 applied to grid 57 through capacitor 61, to prevent a false operation of trigger B.

Title: Improvements in or relating to cathode ray tubes
IPC: H04N5/12
Filed: 1936-11-03
Abstract: 478,151. Television receivers. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Nov. 3, 1936, No. 29938. Convention date, Nov. 14, 1935. [Class 40 (iii)] A signal train comprising vision signals and relatively negative synchronizing signals is applied at El, E2, to vary the cathode potential of a gas-filled discharge tube Th1 whose grid is earthed. The synchronizing impulses thus render the tube conducting to discharge a condenser C2 charged over resistance R3 and so provide a line deflecting potential. A condenser C4, charged over resistance R4, is discharged by a gas-filled discharge tube Th2 to provide a frame deflecting potential. The tube Th2 is rendered conducting by an impulse passed over condenser C3. The normal line impulses passing over C3 are insufficient to render tube Th2 conducting, but when a frame synchronizing signal, constituted by a cessation of the line synchronizing signal, occurs, condenser C2 charges to twice its normal value, the impulse passing over condenser C3 is then of sufficient amplitude to render tube Th2 conducting.

Abstract: 364,674. Fluid-pressure brakes. INDIA-RUBBER, GUTTA PERCHA & TELEGRAPH WORKS CO.,. Ltd., 106, Cannon Street, and AVERY, W. L., of India-Rubber, Gutta. Percha & Telegraph, Works Co., Silvertown, both in London. Oct. 8, 1930, No. 30125. [Class 103 (i).] In fluid-pressure brake apparatus for aircraft comprising a main device for supplying pressure fluid to brakes on the two sides of the aircraft and a pair of auxiliary devices for supplying pressure fluid each to a brake on one side of the aircraft, for steering, a valve is provided adapted to close the conduit leading from the main pressure supplying device to a brake when pressure fluid is being supplied to the brake by the auxiliary pressure supplying device so as to prevent the supply of pressure fluid to both brakes. The apparatus shown comprises a main pressure device 10 operated by a handlever 11 to force fluid to both brakes through conduits 14, 15, 16, 19, 20 and auxiliary pressure pistons and cylinders 17, 18 operated by the rudder bar 123 to supply fluid through the conduits 19, 20 to one or other of the brakes. Each auxiliary device comprises a fixed .cylinder 23, within which is a movable cylinder 24 provided with an end cap 33 clamped by means of a screwed sleeve 35, 36 and nut 38 to a diaphragm 32, the outer edge of which is clamped between the two parts 29, 30 of the end cap of the cylinder 23. A lantern valve 41 slidable in the sleeve 35, 36 against a spring 44 is urged away from its seating 43 by a spring 49 abutting on the sleeve. The conduits 15 or 16 and 19 or 20 leading to the main pressure device 10 and to the brakes are connected respectively to the passages 50, 48. The pressure piston 26 may be normally held in its inner position by a spring 47 so that the piston-rod 21 is clear of the rudder bar 123. When the main pressure device is operated, fluid is supplied to both brakes past the valves 41 and flows also through the apertures 42 in the valves to the cylinder 24 to force the pistons 26 outwardly so bringing the piston-rods into engagement with the rudder bar. The piston 26 abuts on a projection 45 on the cylinder 24 and so holds the valve open at this time. If then the bar is rocked, to force in one piston 26, additional fluid is supplied to the corresponding brake through the valve apertures 42 and passage 48, the valve being seated by the differential fluid pressure due to the greater area of the cap 33 compared with that of the diaphragm 32.
