Abstract

860,539. Discharge tubes. MULLARD Ltd. Dec. 11, 1957, No. 38498/57. Class 39(1). A cold cathode gas-filled voltage-reference discharge diode comprises two electrodes 21, 22, Fig. 4, each electrode having a working portion in the form of a rectilinear rod 11, 12, the rectilinear portions being co-planar and inclined with respect to each other at an angle x between 2 degrees and 15 degrees, preferably between 4 and 6 degrees. The electrodes can be of tungsten or molybdenum and can have a diameter of 1 mm. In the construction shown in Fig. 10, the rods 21, 22 are bent towards each other for a short distance and then bent so as to diverge from each other and form the working portions 11 and 12. The tube is processed by heating the electrodes by ionic bombardment, e.g. by passing an alternating current between the electrodes, in an atmosphere of hydrogen and then removing the hydrogen and replacing it by an inert gas or inert gases such as the rare gases. The electrodes can then be heated by further ionic bombardment. The final filling of the tube can be a mixture of neon and xenon.
