Abstract

418,090. Thermionic valve holders. LOEW, R., and LAZAR, E., 9a, Spittelauerplatz, Vienna. Nov. 20, 1933, No. 32330. [Class 39 (i).] Electric lamp holders and thermionic valve sockets are provided with contact devices each consisting of a spring- influenced metal strip which is otherwise unsecured and is slidably guided between abutments along guides in an insulating body, and comprises a contact-making part and a terminal end for a lead wire which perform a common positive movement when a lamp or valve is inserted. Fig. 8 shows a thermionic valve holder with apertures v to receive contact pins which bear on the portion b of a contact strip a provided with a soldering eye e for a connecting wire and with aT-shaped end r which can be bent to pass through a widened portion of a slot u when a helical spring f is compressed.
