Abstract
1,109,332. Cold-cathode tubes. CERBERUS A.G. 17 March, 1966 [17 March, 1965], No. 11688/66. Heading H1D. A gas-filled overvoltage protector tube includes a pair of opposed planar electrodes each of which has rounded edges, a thickness of not less than 1 mm., and major faces each having an area not less than 30 (mm.)<SP>2</SP>, the spacing between the electrodes, and their thermal capacity, being such as to ensure that, when the tube is loaded at 1000 watts with 10 amps r.m.s. current, a fusion bead forms at the surface of the electrodes to produce a shortcircuit prior to destruction of the hard glass envelope of the tube. Each electrode is preferably of nickel coated with calcium oxide and has a channel 3a, Fig. 1, in its rear face within which its lead-in wire 3 is staked (Fig. 3, not shown) and brazed. The filling is a mixture of argon, hydrogen and tritium at 80 torr. The tube has a polyethylene clip 12, Fig. 4, mounted on the exhaust tip end of the tube, two nickel channel members 10 extending along opposite sides of the tube, each having one end hooked in the clip and the other end spot-welded to the externally extending portion 7 of a respective lead-in pin, whereby the tube may be readily introduced into the contact spring fixture of a fuse-box.
