Abstract

Mejoras en sistemas de comunicación caracterizadas por la producción de impulsos, un tubo del tipo de gas para descargar de electrones teniendo un potencial de encendido predeterminado, medios para iniciar la conducción de dicho tubo, un condensador, y medios de conexión para conectar el citado conductor, a los electrodos respectivos del citado tubo para que este condensador se cargue por el paso de la corriente durante la conducción de dicho tubo, en el que la carga en dicho condensador se aplique a dicho tubo para rebajar la diferencia de voltaje a través de dicho tubo durante la conducción en el mismo y además el control de la extinción del tubo.
