Abstract
Conjunto de cañón electrónico para tubos de rayos catódicos que incluyen una pluralidad de electrones de reja y una unidad de cátodo de calentamiento directo soportados de modo que estén separados mutuamente, caracterizado porque la unidad incluye por lo menos un filamento que está tenso entre un par de elementos de soporte, teniendo el filamento o cada filamento un elemento emisor de electrones situado en el y porque, para el filamento o para cada filamento, uno de los dos elementos de soporte incluye un dispositivo de juste por medio del cual puede ajustarse la posición del elemento emisor de electrones respecto al electrodo de reja adyacente.
