Abstract
249,397. Pressland, C. Aug. 13,1925. Vacuum tubes.-A thermionic valve-holder comprises parallel sockets each made by .bending a coiled spring so as to form a socket portion a<5> receiving a valve leg and a coiled support a<6> which extends at right angles to the socket portion and is secured at the end to an insulating support consisting either of a single recessed ring or of two rings p, q. The socket portions may be surrounded by rubber sleeves.
