Abstract

Perfeccionamientos en tubos de rayos catódicos caracterizándose porque se establece un sistem ade enfocado para enfocar el rayo electrónico y un órgano ferro-magnético dispuesto alrededor del cuello del tubo a una distancia del sistema focal tal qeu ejerce un efecto despreciable sobre dicho sistema pero que establece una pista o trayectoria de baja reluctancia para la desviación de flujo de dicho sistema por lo cual se obtiene un componente transversal del campo focal magnético en el cuello del tubo ajustándose angularmente el dispositivo ferro-magnético con respecto al eje del tubo y con ello variar la posición del rayo.
