Title: Improvements in electric discharge lamps
IPC: H01K11/00
Filed: 1934-10-05
Abstract: 444,119. Discharge lamps. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Patent Treuhand Ges. fur Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin) Oct. 5, 1934, No. 28573. [Class 39 (i)] In an anodic incandescent lamp the anode consists of a plurality of fine wires the free ends of which face the cathode or cathodes. The anode may consist of tungsten or tantalum carbide and may be coated, with the exception of the free ends, with magnesia to limit the discharge to the ends. A filling of gas or vapour, such as caesium, at a pressure insufficient to permit of cumulative ionisation, or a grid, may be used to reduce space charges. The cathodes may be coated with oxide and may be directly or indirectly heated. Blackening of the envelope may be reduced by using a cathode consisting of thoriated tungsten or coated with caesium, or by coating the interior of the envelope with cryolite or sodium chloride. One or two rods 9, Fig. 2, are secured in the pinch 2 and support wires 10, the ends of which face an indirectly-heated cathode 8. In another form, a member 13, Fig. 3, of frusto-conical shape, has the whole of its inner surface studded with wires 14. The anode may consist of metal strips 16, Fig. 4, which are joined at their ends by cross-pieces 17 and support wires 18. Seriesconnected filaments are supported from the pinch by rods 20 through a cross-piece 21 and hooks 22, 23. Each filament is arranged in front of a row of anode wires. The wire supports and also the filaments may be arranged on concentric circles. In another form, the cathode 26, Fig. 8, which consists of a directlyheated helix, surrounds an anode in the form of a rod 24 and wires 25. The heater for the cathode may be in parallel with the discharge or may be heated separately through a transformer. When continuous-current is used, the heater may be connected to the supply voltage in series with a resistance, e.g. an incandescent filament, which may be located in the discharge lamp. The anode wires may be straight or consist of helices. Specification 412,356 is referred to.

Abstract: 668,892. Electric analogue calculating systems. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. Sept. 18, 1950 [Nov. 15, 1949], No. 29245/49. Class 37. [Also in Group XL (b)] In apparatus for integrating a function, e.g. voltage, recurrent trains of electrical impulses are produced by causing a light-spot to perform successive sweeps across a graticule G, Fig. 2, in front of a photo-electric cell PE, the effective lengths of the light sweeps and thus the number of impulses in a train are varied according to the amplitude of the function, and the total number of impulses produced is counted. As shown in Fig. 2, a mask M moved according to the values of the function varies the effective length of the sweep of a C.R.T. screen. The cell PE is connected to a counting circuit through an amplifier A. The mask may be fixed to a pointer which follows the curve of the function, thus obtaining the area under the curve, or to a slider arm SL, Fig. 3, which is moved by a servomotor S so that the voltage produced by a potentiometer T balances a voltage to be integrated applied to terminals V, V<SP>1</SP>. In a modification, a square waveform whose length depends on the values of the function is applied to the control grid of the C.R.T. to vary the period of illumination of the screen.

The cavity electrodes of the parent Specification are constructed of two or more metal body sections, each formed with a shaped recess, which sections are assembled together so that the recesses co-operate to form the cavity. The sections may be pressed from sheet metal, iron sections being joined by spot or argon-arcwelding, and aluminium sections being joined by cold-welding, grooves being provided in the inner surface of at least one of the sections to receive support wires which are trapped between the sections during the welding. In Fig. 2 (not shown) two sections stamped from iron sheet are secured together by spot welding the flanges 16. Alternatively two sections may be formed in a single sheet of metal and then folded and welded to form the electrode. In an electrode of slightly modified shape, Figs. 3 to 5 (not shown), the cylindrical flange 11, 12 at the end of the flared part 15 is omitted. The sections may alternatively be formed by casting or moulding or by pressing and sintering a metal powder. The cavity may be either approximately spherical or ellipsoidal initially, but the spherical shape tends to an ellipsoidal equilibrium shape during operation owing to sputtering and redeposition of metal. The electrodes are used in a fluorescent lamp having a filling of neon and argon at a total pressure of 6-10 mm. Hg together with mercury vapour which may be supplied from a reservoir at one end of the envelope.
