Abstract
495,087. Converting. URMENYI, L. Jan. 29, 1937, No. 2610. Void. Convention date, Feb. 1, 1936. [Class 38 (ii)] In a converting arrangement comprising a grid-controlled discharge device commutation is effected by means of an auxiliary anode which is connected, at the moment commutation is desired, to a source of voltage through a condenser. In the form shown, an auxiliary electrode 9 is connected through a condenser 10, battery 12 and switch 13 to the star-point of the transformer 2. When the switch 13 is closed the arc transfers to the electrode 9 but as the condenser charges the voltage of the electrode reduces and the arc extinguishes or transfers to the next conducting anode. When the switch 13 is opened the condenser discharges through the resistance 11. In a modification the switch 13 is omitted and the electrode 9 grid controlled. In a further modification the electrode 9 is arranged nearer the cathode than the main anodes and is connected through the condenser 10 either directly or through a battery to the anode to be extinguished, by a rotary switch. In a further modification, each anode is provided with an auxiliary electrode, these electrodes being connected to the condenser through a rotary distributer, either to a battery or to the associated anode. In a modification of this in which each auxiliary electrode is connected to its associated anode through a condenser a battery is connected in parallel with the condenser through a resistance so that the condenser discharges to reduce the voltage on the auxiliary anode.
