Abstract

Mejoras introducidas en el objeto de la patente principal nº 225.734, o sea, en la fabricación de electrodos fríos y de forma hueca para aparatos de descarga eléctrica, electrodo en cuya pared interior se ha fijado al menos una pequeña pieza que lleva al menos un metal de las tierras raras en estado metálico, caracterizado por el hecho de que el electrodo, provisto con esta pieza, es sometido a descargas eléctricas en una atmósfera de helio que únicamente contiene pequeñas proporciones de impurezas, en particular en lo que se refiere al contenido en oxígeno, con una presión absoluta de algunos milímetros de mercurio en frío.
