Abstract
109,188. British Thomson - Houston Co., (General Electric Co.). Dec. 27, 1916. Drawings to Specification. Arc lamps. vacuum tubes.-A sealed envelope enclosing electrodes, one at least of which operates at incandescence, contains iodine with or without inert gas such as argon. The iodine may be introduced from a side-tube which is afterwards sealed off. When the apparatus is in use, ihe pressure of iodine vapour is at least half a millimetre of mercury; a pressure of 50 mm. is advantageous. That of the inert gas may be several centimetres. Iodine reduces the drop in electric pressure, and the liability to conduct in the wrong direction. A rectifier may have an incandescent cathode of tungsten or other material and an anode of tungsten, molybdenum, copper, or, when inert gas is present, graphite. Specification 5557/15 is referred to.
