Abstract

Mejoras en válvulas termoiónicas caracterizado porque comprende una ampolla dividida en dos partes por un disco de metal sellado a través de la misma, de la cual una parte contiene el conjunto de electrodo de cátodo y rejilla montado en la misma, estando el ánodo fijado a dicho disco de modo que esencialmente forme parte integral del mismo.Improvements in thermionic valves characterized in that it comprises an ampoule divided into two parts by a metal disc sealed through it, of which one part contains the set of cathode electrode and grid mounted thereon, the anode being fixed to said disc so that it is essentially an integral part of it.
