Title: Improvements in electrodes for electric discharge tubes
IPC: H01J19/02
Filed: 1924-07-23
Abstract: 240,944. General Electric Co., Ltd., and Bartlett, A. C. July 23, 1924. Vacuum tubes. - In thermionic rectifiers and like discharge tubes of the kind provided with a cathode filament comprising two parallel parts and with an anode comprising two cylinders connected together and each surrounding a straight filament part axially arranged within the cylinder so that there is no electrostatic force on the filament due to the voltage difference between the anode and filament, the anode is formed as two nearly closed cylinders connected together and is so arranged that the looped filament assembled on the pinch can be easily inserted into position within the anode from one end. The anode is formed from nickel or like metal sheet bent to form openended cylinders a, b connected at the centre on one side by a flat bridge c and is carried by supports d from a re-entrant tube at the end of the bulb remote from the pinch. The tungsten filaments e, f are attached at one end to lead-in supports g, h carried by the pinch and at the other end are welded or pivoted to a bridge j carried by hooks o. The hooks o may be provided with a spring to compensate for filament expansion and are carried in non-conducting bushes n in a support m on a rod k secured by a clip to the lower end of the pinch. In constructing the rectifier, the filament system is assembled on the pinch which is sealed to the envelope and the anode is slid endwise over the filaments and its supporting re-entrant tube sealed to the envelope.

[Also in Division C7] A magnetic chuck 20 holds a workpiece 15 while a tool 10 electrochemically machines a bearing race therein (see Division C7). The chuck is rotated by a shaft (21) (Fig. 3, not shown) and receives a current through a slip ring assembly (28, Fig. 3) which applies this current to a pair of coils 30 located within the chuck. Thereby a magnetic field is generated which passes from one pole of the coils 30, through the chuck's cylindrical housing to parts 32, 33, the workpiece 15, and through parts 35, 36 to the other pole of the coils 30. Parts 37 and 38 are of magnetically insulating material.

Variable-speed epicycdic gearing is comprised in a sectional paper-machine drive of which several may be driven from a common power shaft such as 10, Fig. 1. For each unit, there is a loose sleeve 31 on shaft 10 adapted to be connected thereto by a clutch 37. The sleeve drives one of a pair of coaxial shafts 24, 13 between the adjacent ends of which the sun-and-planet train 22. 21, 20 is arranged. The planets 21 are supported on a loose worm wheel 44 which is driven through an auxiliary variable gear and a worm. Thus by varying the ratio in, say, an expanding-pulley gear 50, the worm, not shown, is driven variably from chain 60, and so the speed of internal wheel 20 and shaft 13 are varied by controlled small amounts. The gear 50 is driven through a chain 57 from sleeve 31. A casing 17 encloses the toothed gearing.

Abstract: 720,538. Gas-burner igniters. GREAVES, A. H. Aug. 19, 1952 [Aug, 2, 1951], No. 18324/51. Class 75 (3) Apparatus for effecting the remote ignition of gas burners has a tube, having an outlet at or near the burner to be ignited, supplied with an air/gas mixture on operation of a manually operable means which automatically effects the  delayed ignition of the mixture at the inlet end of the tube after the tube is filled with the air/gas mixture so as to cause a flame to travel through the tube and flash from the outlet end thereof, the manually operable means being automatically returned to its initial position on release. A gas tap 16 is pressed inwardly so as to press a spindle 15 against a ball 13 which in turn depresses another ball 23 to open a valve 20 thus admitting gas to a nozzle 11. The tap 16 is then turned and by means of a cranked arm 24 engaging a cam-shaped slot in a plate 26 attached to the top 16 an igniter element 25 is moved into the path of the air/gas mixture and at the same time engages an end 30 of a metal bar 29 to complete an electric circuit from a pair of batteries 27. In the event of failure of the batteries, the air/gas mixture is manually ignited through an aperture 40. The tap 16 is returned to its initial position before rotation by a spring 32 and is then pushed outwards by a spring 14. The tap 16 cannot be rotated in its outer position.

Abstract: <PICT:0948170/C1/1> <PICT:0948170/C1/2> <PICT:0948170/C1/3> Hollow glass articles, e.g. vases, cover bowls, chandeliers, giving excellent light refracting and diffusing effects are obtained by freely bulging the glass out of local apertures in hollow moulds, the bulges having a "fire finish" on both sides. The bulges may be of irregular shape and provided only in local areas.  Fig. 1 shows an article provided with bulges 3 of variable wall thickness. An article may be assembled from plates provided with bulges.  One type of shaping mould comprises a sectioned grid-like arrangement of metal rods, Fig. 11, which may be electrically heated or hollow to conduct heat transfer fluid.  After introduction of the molten glass a pressure difference is applied to cause the glass to bulge through the apertures.  A hollow prismatic article is formed in the five-part mould, Fig. 15, the parts being composed of flat metal rods 17 meshed in a cellular structure.  A glass bulb introduced through the top plate opening is allowed to expand by application of a pressure difference, i.e. either an overpressure, or suction applied to the mould enclosure (Fig. 16, not shown).  The mould can be pivoted away from the finished article.

Abstract: 910,827. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. April 17, 1961 [May 25, 1960], No. 18401/60. Class 39 (4). [Also in Group XXVIII] A duct system, e.g. that installed in an operating chamber of a CO 2  gas-cooled nuclear reactor installation, comprises a duct confined within a longitudinal radiation-shielding structure and means for detecting leakage of fluid from the duct into the space defined by the outer walls of the duct and the inner walls of the shielding structure. In one embodiment (Fig. 4), a CO 2  carrying duct 35 is confined within a longitudinal shielding structure 36 formed by the under-face of a concrete biological shielding 37 and a thick-walled, U -sectioned cast-iron structure 38. A pipe 39, which penetrates a wall of the structure 38, connects with the inlet side of an evacuating pump 41, the outlet side being connected by a branch pipe 43 to a radio-activity monitor 42. Pump 41 is driven by an electric motor 48 which, under normal conditions, drives it at a slow speed but, should a leakage of CO 2  from the duct 35 occur, the subsequent increase in pressure in the pipe 39 is sensed by a pressure-sensitive pump controller 50 which operates through signal lines 51 connected to the pump motor 48 to increase the speed of the pump 41. The outlet side of the pump 41 normally leads to the atmosphere through pipe 52 and valve 55 but, should radioactive contaminants be present in any leakage of CO 2  removed by the pump 41, the radioactivity monitor 42 emits signals through signal lines 59, 60 which result in opening of a valve 56 and closing of the valve 55. Valve 56 located in a pipe 53 connecting the outlet side of the pump 41 with a scrubbing tower 54 through which a pump 61 circulates Na 2 CO 3  solution. Clean CO 2  gas passes through an outlet 63 to the atmosphere and radio-active contaminants are discharged in sludge form through a drain 64. In an alternative embodiment (not shown), leakage from the duct is detected by means of devices of the infra-red gas analyser type and sensitive to CO 2  gas.

In a line-scan time-base of the kind in which an E.H.T. voltage is obtained by rectifying the fly-back pulses, the magnitude of the fly-back pulse and hence both the E.H.T. voltage and the line scan current are stabilized. The linescan amplifier 1 driven by a sawtooth input 20 is auto-transformer coupled to the scan coils 13, the E.H.T. rectifier 10, and booster diode and capacitor 12, 9. During fly-back, positive pulses are applied from the auto-transformer to the grid and anode of a valve 21, the grid potential being adjustable by a capacitative potential divider 27, 29. The cathode of valve 21 is biased by a reference tube 32 and the H.T. supply so that the valve only conducts when the magnitude of the fly-back pulse applied to the grid exceeds this bias, and the resulting drop in anode potential correctively alters the bias on the amplifier 1. In a modification, Fig. 2 (not shown), the reference tube 32 is replaced by a non-linear resistor, and the grid-voltage of valve 21 is obtained from a potential divider across capacitor 9.
