Abstract: 818,075. Electric lamps. GENERAL ELECTRIC CO. March 14, 1956 [March 29, 1955], No. 7985/56. Class 39(2) An infra-red generating lamp comprising a sealed envelope of vitreous material containing a coiled tungsten filament designed for operation at a temperature of about 2400‹K. to 2500‹K. is characterized by the pitch of the coil being between 140 per cent and 220 per cent, preferably in the range of 180-200 per cent, and by the wire diameter and length of the coil being proportioned to dissipate in excess of 0.5 watts per square millimeter of wire surface area at a current density in excess of 0.029 amperes per milligram weight of the wire. The term "per, cent pitch" is defined as the ratio, in per cent, of the distance between centres of adjacent coil turns and the diameter of the coil wire. The coils are preferably prepared at a pitch of about 180 per cent and ultimately stretched to 196 per cent pitch during assembly into the lamp envelope. In the example the lamp comprises an elongated tubular envelope 1 consisting essentially of fused silica, such as clear crystal quartz, transluscent sand quartz, or a quartz-like glass, containing approximately 96 per cent silica, and containing a filling of rare gas such as argon, krypton, xenon, or mixtures thereof, preferably at a pressure of about one atmosphere. The opposite ends of the filament 2 are connected to leading-in conductors 3 by means of short coils of tungsten wire 5 fitting tightly around the prospective leading-in conductors and screwed into the ends of the filament. The intermediate portions 7 of the leading-in conductors within the flattened press or sealed portions 4 of the envelope are flattened to a thickness of between 0.01 and 0.025 mm. by a longitudinal rolling operation which produces a longitudinal crystal orientation therein. Intermediate supports for the filament are provided by centrally perforated spaced discs 6, preferably made of a refractory metal such as tantalum which also functions as a getter.

Title: Improvements in or relating to photo-electric cells

Filed: 1937-03-19
Abstract: 491,326. Photo-electric cells. FERRANTI, Ltd., and DARBYSHIRE, J. A. March 19, 1937, Nos. 8074 and 8075. [Class 39 (i)] In a photo-electric cell of the type in which an alkali metal is deposited on an oxidized metallic surface, the alkali metal is liberated by passing an electric current from an external source through a heater wire in the cell and applying part of the heat generated to a container adjacent the wire but not conductively connected thereto, which carries a mixture or compound capable of liberating the alkali metal when heated. According to a subsidiary feature, the cathode is heated during operation to a temperature of 600-880‹ C. by passing current through it ; the thermionic emission is just evident and the sensitivity is thereby increased. In the form shown the anode 3, a closed loop of wire, and an auxiliary electrode 4 are disposed on opposite sides of a tungsten cathode 5 formed as a heater surrounding a ceramic vessel 6 containing a mixture of caesium chromate, aluminium powder and chromic oxide ; calcium and caesium chloride or caesium azide are other suitable materials. The tungsten cathode is first oxidized by a glow discharge in oxygen at 2 mms. pressure between the anode 3 and electrode 4. The tube is evacuated, the cathode heated to 650‹ C. to de-gas it and then to 900‹ C. to liberate caesium from the vessel 6. After baking at 160‹ C. the tube is evacuated and sealed off. Modifications are described in which the de-gassing of the cathode at 650‹ C. is omitted. The first Provisional Specification describes generally a photoelectric cell in which the cathode is operated at a higher temperature than the anode. Into such a cell caesium may be introduced by heating a side-tube containing caesium chloride and calcium shavings, or caesium oxide.
