Abstract
499,792. Converting. SOC. ANON. POUR LES APPLICATIONS DE L'ELECTRICITE ET DES GAZ RARES, ETABLISSEMENTS CLAUDE-PAZ & SILVA. July 29, 1937, No. 21075. Convention date, June 22. [Class 38 (ii)] [Also in Group XL] In vapour electric discharge apparatus comprising one or more metal parts performing the functions of grids and intended for the conversion of currents and voltages, at least one of the grids 11 is connected by a conductor to an auxiliary electrode or "probe" 13 placed in contact with the discharge arc, the conductor having no solid connection with the supply circuits of the apparatus, and an alternating control voltage 12 is applied in the circuit thus provided. Greater regularity of control and a reduction in the control power is obtained. A second grid may be provided to which a variable voltage is applied to enable the anode voltage-critical control grid voltage characteristic to be varied. The probe may if desired be surrounded by a control grid ; the control voltage is then applied to this grid and not between the probe and main control grid. Specifications 379,271 and 474,759, [both in Group XL], are referred to.
