Abstract

804,414. Holders for thermionic valves. BRISTOL CO. Feb. 7, 1957, No. 4221/57. Class 38 (1). [Also in Group XXXVII] A magnetic screening can 26 for an electrical device enclosed in a metal case 13 having plug-in engagement with a socket 10, comprises bent-in tongues 32 and bayonet catch formations 27 cooperating with bosses 12 on the socket so that when the catch is released the can 26 may be withdrawn until the tongues engage a circlip 35 on'the case 13 whereby complete removal of the can is impossible. A spring 30 is interposed between the ends of the case and can. The device shown is the relay disclosed in Specification 802,758, [Group XXXVII], but alternatively may be an electron emissive device.
