Abstract

Mejoras en conjuntos de cátodo para una válvula termoiónica similar, caracterizado por la combinación de un elemento de soporte, una pluralidad de varillas dispuestas circunferencialmente y montadas en el elemento de soporte, un primer anillo que se dirige alrededor de las varillas, cerca de uno de sus extremos, y está unido a las mismas, un arrollamiento compacto y substancialmente cilíndrico que rodea a las varillas y está soportado por las mismas, estando el arrollamiento en contacto con el primer anillo, y un segundo anillo dispuesto, alrededor de las varillas y unido a ellas, en el otro lado del arrollamiento, por lo que el arrollamiento se mantiene en posición entre los dos anillos.Improvements in cathode assemblies for a similar thermionic valve, characterized by the combination of a support element, a plurality of rods arranged circumferentially and mounted on the support element, a first ring that runs around the rods, near one of its ends, and is attached to them, a compact and substantially cylindrical coil that surrounds and is supported by the rods, the coil being in contact with the first ring, and a second ring arranged, around the rods and attached to them, on the other side of the winding, whereby the winding is held in position between the two rings.
