Title: Improvements in or relating to circuits for cathode ray tubes and methods of operating the same
IPC: H01J3/02
Filed: 1947-07-10
Abstract: 624,832. Cathode-ray tubes. CINEMATELEVISION, Ltd., and BUCHANAN, W. H. July 10, 1947, No. 18362. [Class 39 (i)] In a cathode-ray tube of the type comprising a cathode heated by electron bombardment, a modulator electrode for controlling the electron emission from the cathode, and an anode, unidirectional potential pulses are applied periodically between the cathode and the source of the bombarding electrons. Only those electrons emitted thermionically from the cathode without including bombarding electrons or secondary electrons emitted from the bombarded cathode surface are then utilized to form the operative cathode-ray beam. As shown, the cathode 3, which may be shaped so that the emissive surface is a sharp point, is bombarded by electrons from a helical filament 4 surrounding it. The unidirectional potential pulses are supplied between the cathode 3 and filament 4 from a rectifier 7, 8 whose alternating potential input is derived from a time-base' circuit so that the cathode 3 is only bombarded during the flyback periods of a scanning process performed by the electron beam, for example in television, radar or oscillography. Potentials are supplied to the modulator electrode 5 across the resistance 9 to suppress emission from the cathode 3 towards the anode 2 in those periods when the cathode is under bombardment. To ensure that the modulator electrode is not held so negative that bombarding electrons are repelled from the part of the cathode 3 adjacent to the.modulator electrode, a charge-leakage path is provided between the electrode 5 and the filament 4 through the diode 14. In an alternative method, modulating potentials are supplied to the anode 2 to suppress emission from the cathode in the bombardment periods.

Title: Improvements in and relating to the production of atmospheres for metallurgical and other purposes
Inventor: WHEELEY EDWARD ALBERT
IPC: C21D1/76
Filed: 1950-07-24
Abstract: A non-oxidizing atmosphere for use in metallurgical processes is produced by burning a liquid or gaseous hydrocarbon-containing fuel with a gas containing predominantly nitrogen together with oxygen e.g. air, removing carbon dioxide from the gaseous products, adding hydrogen thereto, and passing the mixture at a high temperature over a catalyst whereby the added hydrogen is caused to react with any residual oxygen in the said mixture.  The carbon dioxide formed may be removed by treating the combustion gases with alkanolamines e.g. one or more ethanolamines, and the added hydrogen may be conveniently obtained mixed with nitrogen by the cracking of ammonia as described in Specification 462,531. Most of the water formed may be removed by condensation prior to the removal of carbon dioxide, and the last traces by passing the gases through a solid adsorbent e.g. silica gel.  Sulphur compounds in the gases are oxidized to sulphur dioxide or trioxide which may be removed by known scrubbing processes.

Abstract: 578,378. Draught regulators for furnaces. MCINTOSH, R. R. Nov. 12, 1943, No. 18858. Convention date, Oct. 12, 1942. [Class 51 (i)] The draught in a locomotive smoke-box 2 is regulated by admitting atmospheric air through an opening 16 in the upper wall of a horizontal open-ended conduit 8, the opening being controlled by a vertically movable valve 18 guided by rods 28 and provided with a weighting system which adds or removes weights to vary the loading and so provide for the valve to open at different predetermined values of suction pressure in the. smoke-box. The valve. 18, which is of such weight and size, that when unloaded, it opens to admit air when the suction pressure reached a predetermined minimum value, is carried by a shaft 19 fitted with a collar 34 on to which may be separately lowered weights 37, 38 so selected that the valve-opens only when predetermined intermediate and high suction pressures in the smoke-box are attained. The weights are formed with flanges 48, 61 adapted to be engaged by counterbalanced fork members 47, 60 which are carried on the lower ends of rods 45, 58 secured to pistons 46, 59 operating within cylinders 39, 40. The movement of the pistons and thus the addition or removal of the weights 37, 38 may be effected by fluid pressure or electrically and may be controlled manually or in accordance with the rate of fuel feed or with variations in the cut-off of steam supplied to the driving cylinders of the locomotive. In the fluid-pressure arrangement shown in Figs. 2, 3 the reverse arm 67, which is oscillated by the cut-off setting controls in the locomotive cab, carries an arcuate plate 71 to which are adjustably secured cam shoes 75, 76 serving to operate valves 77, 78. The cam shoes are adjusted to actuate the valve 77 at a particular cut-off setting and the valve 78 at a higher setting, these valves controlling the passage of pressure fluid, e.g., air, from the supply main 82 to the upper ends of the respective cylinders 39, 40 and thus effecting the successive addition of the weights 38, 37 to the valve assembly 18. Hand-operated valves 101, 102 are provided in the pressure-fluid system to permit manual control if desired. In a modification, the cam shoes 75, 76 actuate switches which control the supply of current to solenoids effecting the movements of the rods 45, 58 carrying the weight-manipulating forks 47, 60. Fig. 9 shows a further arrangement for an oilfired locomotive in which the passage of pressure fluid from the main 82 to the cylinders 39, 40 is controlled by valves 104, 105 interconnected with a hand-operated valve 107 which regulates the supply of fuel to the burner 109.
