Abstract
354,452. Discharge rectifiers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fitzpatrick, J. J. ; 43, West Street, Marblehead, Massachusetts, U.S.A.) June 4, 1930, No. 17288. Convention date, June 25, 1929. [Class 39 (i).] A gas-filled double-wave rectifierhaving an electronemitting cathode heated by means independent of the discharge has two anodes 5, Fig. 1, on opposite sides of the cathode which is surrounded by a box-like shield 13 closed at one end and having discharge openings 17 on opposite sides thereof and located in the plane common to the electrodes. A nickel cathode 8, Fig. 2, which may be located above the anodes as shown, or on a level therewith, is heated by a filament 11. It is coated with barium by applying barium carbonate mixed with a suitable binder which is heated to a temperature of about 1200 C. at which the carbonate is converted into a transparent layer. A conductor 9 supports the cathode and the heater. The anodes may be formed of rod-carbon, graphite or nickel and are made hollow at their upper ends to facilitate cooling. Discharge between the anode supports is prevented by glass sleeves 7. The shield is formed of nickel sheet and is provided with tabs 20 which are bent over to close the upper end. It fits over the cathode with minimum clearance and its lower end extends towards the press a distance sufficient to prevent discharge therethrough. The openings 17, dimensions of which are given, may be formed as rectangular slots, the areas of which are large enough to pass the discharge without undue voltage drop. Argon at a pressure of 80-200 microns may be used as the filling. A drop of mercury may be added as an additional source of positive ions. The Specification as open to inspection under Sect. 91 (3) (a) states also that the rectifier may have only one anode. This subject-matter does not appear in the Specification as accepted.
