Abstract

Mejoras en tubos de descarga eléctrica que incluyen un cátodo, una rejilla que rodea al cátodo, un ánodo substancialmente en forma de anillo que rodea a la rejilla, y una cubierta que rodea a los referidos electrodos, caracterizado por el hecho de que el ánodo tiene una porción inversamente curvada entre sus diámetros internos y externo, dirigida de modo que la superficie periférica externa del anillo está desplazado longitudinalmente de la rejilla y es substancialmente paralela a la superficie interna del anillo que rodea a la rejilla.Improvements in electric discharge tubes that include a cathode, a grid that surrounds the cathode, a substantially ring-shaped anode that surrounds the grid, and a cover that surrounds said electrodes, characterized by the fact that the anode has a portion inversely curved between its inner and outer diameters, directed so that the outer peripheral surface of the ring is longitudinally offset from the grid and is substantially parallel to the inner surface of the ring surrounding the grid.
