Title: Improvements in or relating to electric discharge vessels and processes for the production thereof
IPC: H01J5/06
Filed: 1937-09-10
Abstract: 502,101. Uniting metal to ceramic material by heat; discharge apparatus. SIEMENS & HALSKE AKT.-GES. Sept. 10, 1937, No. 24739. Convention date, Sept. 10, 1936. [Class 36] [Also in Group XL] A gas or metal vapour electric discharge device, such as a high voltage rectifier, consists solely of ceramic and metallic parts, with intermediate control electrodes disposed between the anode and cathode and consisting of individual metallic parts or of metallic layers sintered on ceramic parts, the portions of the ceramic parts to be connected to separate metallic parts having a layer of a base metal powder of high melting point sintered thereon and then being joined to their associated metallic parts by means of hard solder. Fig. 1 shows a discharge vessel consisting of ceramic parts 1 separated by tubular metallic control electrodes 2 which subdivide the voltage between the cathode 3 and anode 4. The surfaces of the ceramic parts 1 that are to be soldered to the adjacent metal parts 2 are preferably metallized by applying thereon a mixture of a finely divided metal such as chromium or nickel and an organic adhesive agent, and heating up to the sintering temperature of the metal in a vacuum furnace. Rings of hard solder such as silver solder are then located within retainers 11 and, on heating sufficiently, penetrate into the gaps at the points of connection, as shown at 12. A metal cap 5 is soldered to the upper end of the vessel, and a ceramic protecting-tube 6 around the anode lead 7 is soldered to the cap 5, after metallizing the ceramic parts of the joints. The intermediate metal parts or electrodes may be connected to condensers in order to attain a uniform voltage distribution. Fig. 5 shows a construction wherein condensers 13 structurally combined with the discharge device are composed of separate rings of insulating material of conical cross-section with a sintered metal coating upon one surface. These condensers are connected to intermediate electrodes 2 formed by sintering metallic layers upon the inner walls of ceramic tubes 1. Specification 475,878 is referred to.

Patent GB-811726-A (GB)
Title: Improvements in or relating to apparatus for use in counting pulses stored in a scaler
IPC: H03K21/00
Filed: 1955-08-30
Abstract: 811,726. Counting-apparatus. JARRELLASH CO. Aug. 30, 1955 [Sept. 3, 1954], No. 24899/55. Class 106 (1). The number registered by a scaling unit, e.g. a multi-gap gas-filled discharge tube, is indicated by applying thereto a number of fixed frequency pulses sufficient to fill or empty the unit and either applying those pulses to a motor driving an appropriately calibrated indicating device or otherwise synchronously operating such a device. In one arrangement, Fig. 3, the scaling unit 19 counts particles 14 on a bed 15 as it is moved along a path 16. The particles are illuminated and a photo-multiplier 12 produces a pulse as each passes. As the bed completes its movement, a switch 21 is closed to energize a relay 23 which opens contacts 20 in the input circuit of the scaling unit and closes contacts 24, 25 so that pulses from a generator 28 are applied to the scaling unit 19 and to the indicating device 29. When the scaling unit is filled, a signal on a lead 33 operates a relay 32 which opens contacts 30, 31 in the leads from the pulse generator 28. The indicating device 29, which has then registered the complement of the number previously registered by the scaling unit, may be calibrated to give a direct reading appropriate to the counting operation being performed. In a modification, the counting action in the scaling unit is reversed and the latter produces a control signal to cut off the supply of pulses when it has been returned to zeroregistering condition. In a different arrangement, Fig. 5, several photo-multipliers 40, 41, 42 control respective multivibrators 43, 44, 45. Pulses derived from the latter are counted by corresponding scaling units 49, 50, 51. The pulses originating from the photo-multiplier 40 occur at a greater frequency than those in the other channels and when the scaling unit 49 is filled, a relay 52 is operated which, by contacts 54, renders the multivibrators inoperative, and energizes a pulse generator 57 and timing devices 58, 59. The pulse generator supplies pulses to the scaling units 50, 51 and, as each is filled, it operates a corresponding relay 70, 71 which, by its contacts 66, 67, cuts off the supply of pulses and, by its contacts 62, 63, stops operation of the respective timing device 58, 59. The timing devices then indicate the counts registered by the scaling units 50, 51 at the time when the scaling unit 49 was filled. This arrangement may also be modified so that the fixed frequency pulses step the scaling units 50, 51 back to zero condition.

Title: Improvements in or relating to relief valve
IPC: B64D13/04
Filed: 1954-09-01
Abstract: 761,194. Fluid-pressure servomotor-control systems. GARRETT CORPORATION. Sept. 1, 1954 [Nov. 10, 1953], No. 25382/54. Class 135. A relief valve includes a closure member 20 normally closing passage means 16 between an enclosure 12 and ambient atmosphere and connected to a movable wall 35, means 61 exposing one side 36 of the wall to enclosure pressure, means 63 to expose the other side 37 to atmospheric pressure, and pilot valves operable in response to a predetermined differential between enclosure and atmospheric pressure to reverse the effective pressures acting on the walls to open the closure member. As shown, atmospheric pressure loads the right-hand side of diaphragms 70 and 35 respectively via pipe 83 and via right-hand end of conduit 16, passage 69 and restriction through spring-loaded poppet valve 63. Cabin pressure at 12 reaches the left-hand side of the diaphragms respectively by passage 82 and restriction through spring-loaded poppet valve 61. When cabin exceeds atmospheric pressure by an excessive amount diaphragm 70 first moves against spring 80 to open valve 77 so that cabin pressure in 71 replaces atmospheric pressure in chamber 37 via port 79. Further rise in cabin pressure brings diaphragm 70 into contact with stem 94 of pilot valve 93 which then opens and allows cabin pressure in 36 to be replaced by atmospheric pressure via passage 97, port 89 and pilot valve seat in an adjusting screw 86, chamber 72 and pipe 83. Diaphragm 35 then moves to the left against spring 58 and, through two links and a crank 56, opens the valve 20. For vacuum relief of the cabin, atmospheric pressure via valve 63 and chamber 37 and low cabin pressure via valve 61 and chamber 36 will move diaphragm 35 to the left to open valve 20. When used as an electricallyoperated dump valve high pressure is supplied at 99, e.g. from the cabin compressor. On closing switch 110 solenoid valves 102, 105 open so that the high pressure air enters chamber 37 and atmospheric pressure exists in chamber 36 via passage 97 and port 108 so that diaphragm 35 moves to open the valve. If the high pressure source fails, the electrical valves are operated and high cabin pressure enters chamber 37 via valve 111 and atmospheric pressure enters chamber 36 via 83, 108 and 97 to open valve 20. The valve may be opened manually via cable 55, pulley 54, clutch 50 and a crank and link acting on crank 56. In another embodiment the diaphragm 35 is replaced by an annular diaphragm surrounding conduit 16 and connected to the valve spindle 21 via two spindles and slotted spring- loaded levers, and the valves 77 and 63 replaced by a double-landed piston valve so that as the first opens the second closes.

Abstract: 854,623. Cutting appliances. FANFOLD Ltd. Aug. 1, 1958 [Aug. 14, 1957], No. 25689/57. Class 31 (2). A cutting appliance comprises a holder having a pair of elongated guide members extending parallel to one another with a space therebetween and interconnected at one end, one guide member extending beyond the other guide member and comprising a rod or tube, and a cutting blade mounted on the holder with its cutting edge facing towards the free ends of the guide members and extending across and being exposed solely by said space and being remote from the free end of at least one of the guide members so that the guide members serve to guide a piece of sheet material, introduced between the guide members, to the cutting edge of the blade. As shown, the holder comprises a pair of guide members 1, 2. The guide member 1 is composed of a member 3 having a screwthreaded end 4 to which is secured an extension member 5 of the appropriate length, the member 3 having a semi-cylindrical recess which extends the greater part of the length of the member from the end opposite the end 4, a flat cutting blade 6 being secured in the recess by means of a clamping piece 7 and screws 8. The guide member 2 is formed from a strip of sheet material having at one end a projecting portion 9 which is bent over at right angles to the surface of the guide member and secured, by means of screws 10, to the plane surface of the recess in the member 3. The guide member 2 has a slot 12 to receive the upper portion of the blade 6, which blade portion is prevented from being exposed by means of a guard 14 formed integrally with the guide member 2. The guard 14 has a bevelled surface 15. The appliance is stated to be for cutting, after they leave the printing position, webs of transfer material interleaved between webs of continuous-form stationery. For this purpose, the guide members 1, 2 are inserted from one side between two adjacent webs of stationery so that the interleaved web of transfer material passes between the guide members. When the extension member 5 of the guide member 1 emerges at the other side, the member 5 is grasped and the appliance pulled through so that the web of transfer material is severed by the cutting edge 13 of the blade 6.
