Abstract: 654,974. High-frequency discharge apparatus. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 28, 1948, No. 2606. Convention date, Jan. 29, 1947. [Class 39 (i)] A T.R.S. valve of the gas-filled type for periodically blocking an ultra-high-frequency wave transmission line by means of ionized gas discharges, is characterized in that it is formed by means of a concentric cable, the sheath of which is separated into two sections L, L<SP>1</SP> joined by a metallic wall D, the distance between said metallic wall and the inner conductor of the cable being reduced in a definite region in order to obtain a maximum electric field in the said region, this region being surrounded by a gas-filled, vacuum-tight jacket B communicating with the interior of the cable which is sealed by two transverse vacuum-tight insulating joints J, J<SP>1</SP>. The diameter of the inner conductor changes abruptly at the joints J, J<SP>1</SP>, so that the characteristic impedance of the line remains unchanged. The reduction in diameter of the metallic wall D and of the inner conductor in the region of maximum electric field, where the discharge occurs is also effected in such a manner that the characteristic impedance remains constant. Pre-ionization of the discharge gap is provided by means of an auxiliary discharge between a metal ring A and the metallic wall D which is provided with radially distributed perforations to allow the pre-ionization through the outer conductor. The ring A is supplied through a lead H and is supported by brackets K, K<SP>1</SP> mounted on insulating members C, C<SP>1</SP>. The ring A may be replaced by a toroidal mercury-vapour discharge lamp, in which case the inner surface of the metallic wall D in the region of the discharge is coated with a light-sensitive photo-electron emissive layer. Alternatively the wall in this region may be coated with a radio-active layer; in which case no other auxiliary exciting source is required.
