Abstract: 378,076. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Jackson, H. W. ; 1086, University Place, Schenectady, New York, U.S.A.) May 6, 1931, No. 13402. Convention date, May 29, 1930. [Class 39 (i).] Gaseous discharge tubes are provided with electrodes 5 having an electron-emitting coating on the external surface. The coating is produced by the volatilization of an alkali or alkaline-earth metal compound 6 which is placed in a cavity within the electrode. Each electrode consists of a tube 5 of iron, nickel, &c. mounted over a sleeve 4 through which the lead 3 passes. The compound 6 may consist of caesium azide or nitrate or a mixture of caesium chloride and calcium or magnesium or of a compound of rubidium. The bulb, after the electrodes have been mounted therein, is connected to an exhaust system and baked at about 325‹ C. to drive off occluded gases. The tube is then cooled and the electrodes 5 heated to a red heat by a high frequency inductive field. The products of decomposition escape between the electrodes and the sleeves 4 and leads 3. The gases are removed by the exhaust pump while the caesium &c. condenses on the walls of the bulb and on the electrodes. The film on the bulb is removed by heating it to 325‹ C. while it is still connected to the exhaust system. The bulb is then filled with 70 per cent neon and 30 per cent helium at 24 mm. of mercury. A ballast resistance of about 20000 ohms is connected in series with the electrodes and housed in the base of the device. The tube is aged on alternating current until a uniform corona is obtained over each electrode. The part of the leads 3 within the tube may be made of iron or nickel. Reference has been directed by the Comptroller to Specifications 17646/14,267,142, and 306,960, [all in Class 39 (i), Electric lamps, Arc &c.].

Abstract: 686,477. Protective cut-out systems. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 18, 1951 [May 31, 1950], No. 13643/50. Class 38 (v) A balanced protective arrangement with induction relays A, B at each end of the protected circuit or section 10, the relays having field magnets 2A, 2B, primary windings 1A, 1B on the field magnets, and secondary windings 3A, 3B on the field magnets connected in series with windings on the relay operating magnets 4A, 4B and pilot wires 12, as described in Specifications 298,994 and 298,995 [both in Class 38 (v)] has non-linear resistances 6A, 6B connected across the secondary windings 3A, 3B to limit the voltage applied to the pilot circuit. The resistances are preferably of a type in which the current is an exponential function of the applied voltage and may be of the material sold under the Registered Trade Mark "Metrosil". The use of such resistors limits the voltage applied to the pilot circuit under heavy-fault conditions without materially affecting the sensitivities of the relays to moderatefault conditions. The relays shown have shortcircuited loops 5A, 5B on the field magnets to neutralise the effect of capacity currents in the pilot wires and to provide a bias tending to restrain the relays from operation under heavy loads or throughfault conditions.
