Abstract

Un tubo de descarga con bombilla de materia vítrea tal como el cuarzo caracterizado porque el cierre de su pie se obtiene por medio de un sombrerete cilíndrico metálico ensartado y soldado en la varilla que forma conductor de corriente para el correspondiente electrodo teniendo dicho sombrerete una arista de cierre delgada y biselada a cuyas caras interna y externa se conduce la materia vítrea del pie para soldarse por fusión.A discharge tube with a bulb made of vitreous matter such as quartz, characterized in that the closing of its foot is obtained by means of a metallic cylindrical cap threaded and welded on the rod that forms a current conductor for the corresponding electrode, said cap having an edge of thin and beveled closure to whose internal and external faces the vitreous material of the foot is led to be welded by fusion.
