Abstract: 420,808. Converting. AKT.-GES. BROWN. BOVERI, & CIE, Baden, Switzerland. April 8, 1933. No. 10614. Convention date, April 8, 1932. Addition to 409,331, [Group XL]. [Class 38 (ii)] [See also Group XL] In a gas- or vapour-filled discharge device provided with a control grid as described in the parent Specification, the ignition and extinction of the anode current is determined by the strength of a pulsating exciter arc, the path of which passes through the space immediately in front of the grid, which is charged to a suitable potential. Continuous current from a battery c, Fig. 1, is converted into alternating current by a device which comprises anodes a, connected in parallel, and control grids g, which are negatively biassed with respect to the cathode b by a battery d. A continuous-current source h is adapted to be connected to an ignition anode z, and to the exciter anode e through an alternating-current generator w, the speed of which is controlled in accordance with the desired frequency. In a modification, an inverter comprises grids g. Fig. 2, which are located in front of the anodes a and are connected through resistances r with the exciter anodes e. A phase shifter s supplies current to the exciter anodes. In another form, a rectifier comprises an anode shield, within which are located a control grid, connected to the cathode through an alternating- current source and a resistance, and an exciter grid, connected to the cathode through alternating-current and direct-current sources and a resistance. Current surges upon extinction of the discharge are minimised by condensers, which are connected between each anode, or each control grid, and a single exciter anode, or the exciter anode associated therewith.
