operation of the tube. What I claim is:
According to the invention, a metal discharge An electric discharge adapted to be operated tube comprisi g a metal envelope and for use at at very short wave-lengths comprising a metal very short wave-lengths in which a glass proenvelope, a plurality of lead-in conductors extective hood surrounds one or more lead-in wires tending into said envelope, a glass protective hood led through the envelope of the tube and consurrounding said lead-in conductors, supply connected by substantially flexibl conductors to tacts on the hood, a plurality of flexible conpp y contacts 011 the protective 110051, is charcluctors each connecting one of the lead-in conacterized in that a conductor shaped in the form cluctors t one of i contacts, d a leafpring of a small Spr ng is arranged between each conductor element interposed between each lead-in wire a d t e inner Surface of the Side lead-in conductor and the inner surface of said of the protective hood so as to be in mechanical hood and in mechanical Contact th th contact therewith. EDUARD GERHARDUS DORGELO.
The incidence of sparking and arcing to the protective hood is thus at least reduced even in No references cited,
