Abstract: 157,041. British Thomson - Houston Co., Ltd., (General Electric Co.). March 4, 1916. Arc lamps; vacuum tubes; low-pressure metallic-vapour apparatus.-In a rectifier or other device containing inert gas, a cathode 3 is maintained at incandescence by the discharge alone, being carried by a stem 4 of smaller diameter, which may be further reduced for a short distance behind the cathode, while the anode 9 is large enough to remain cool and presents a flat surface to the cathode. Initially, the cathode may be heated by an arc between the anode and a filament 8, which may be coiled around the cathode stem, and electrically connected to it near the cathode. Current for heating the filament may be taken from a special winding 13 of a supply transformer 15. Alternatively, the starting discharge may be produced by the use of a. high electric pressure between the main electrodes, the cathode being preferably pointed to reduce the pressure necessary. The supply transformer may have two secondary windings giving different pressures for starting and working. Suitable materials for the cathode are tungsten, molybdenum, tantalum, and carbon. The anode may be of refractory material or of volatile material such as mercury. The sealed envelope 1 of the device may contain inert gases such as argon, nitrogen, krypton, neon, and hydrogen, at pressures varying from 5-12 mm. of mercury, for low voltages, up to an atmosphere or more; or mercury vapour may be employed. Oxygen, chlorine, water vapour, and the like, should be excluded, although when the electrodes are of tungsten, molybdenum, &c., a trace of oxygen does no harm.
