Abstract

774,190. Caps and holders for thermionic valves. EDISON SWAN ELECTRIC CO., Ltd. May 17, 1955 [May 17, 1954], No. 14467/54. Class 38 (1). A valve-holder has an upstanding locating surface which is divided into quadrants 14, 15, 16, 17, the quadrants 14, 16 being of larger diameter than the other two and the quadrant 14 being longer circumferentially than quadrant 16, this asymmetry ensuring that a valve base 6 formed with corresponding quadrantal formations 4 ... 7 can be inserted in one position only. The quadrants prevent tilting of the valve when incorrectly presented, thereby preventing incorrect engagement of the contacts, the lengths of the pins 3 being suitably restricted. Asymmetry of the quadrants alternatively may be produced by making opposite quadrants of different diameter.
