Abstract

Mejoras relacionadas con dispositivos de descarga electrónica caracterizadas por medios soportes para filamento o filamentos adaptados para ser calentado por medio de corriente eléctrica que pasa a través de ellos y comprenden varillas soporte de filamento de longitud desigual en las cuales las referidas varillas están sujetas con miembros rígidos transversales a distancias sustancialmente equidistantes de sus extremos de filamentos y están soportadas en los extremos lejanos del filamento por medio flexibles situando las referidas varillas de desigual longitud en relación con cada una de las otras los referidos miembros transversales estando atados juntos para evitar diferencias de dilatación térmica de las referidas varillas respecto una a la otra en sus extremos de filamento.Improvements related to electronic discharge devices characterized by support means for filament or filaments adapted to be heated by means of electric current passing through them and comprise filament support rods of unequal length in which said rods are fastened with rigid members transverse at substantially equidistant distances from their filament ends and are supported at the far ends of the filament by flexible means by placing the referred rods of unequal length in relation to each other the referred transverse members being tied together to avoid differences in thermal expansion of said rods with respect to each other at their filament ends.
