Abstract

469,163. Supply systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 16,1936, No. 31341. Convention date, Nov. 18, 1935. [Class 38 (iv)] [Also in Groups XL and XXXVI] A radio receiver is adapted for use on direct or alternating current supply 1, Fig. 1, by providing spring contacts 6, 7, 8, 9 in the leads inside the set, so that for D.C. supply a known type of D.C.-A.C. converter unit 16 can be plugged into the contacts by means of plugs 14, 15. The switch 2 comprises a pair of safety contacts opened when opening the casing of the receiver, while switch 3 is the main supply switch for the set. The plugs 14, 15 may be constructed as a plug- and-socket unit as shown in Figs. 2 and 3. The contacts 10, 11, 12, 13 are mounted on an insulating member 14 which engages the socket member 22 and opens the closed contact pairs 6, 7, 8, 9. A rib 21 and corresponding portion 23 on the socket prevents incorrect insertion of the plug unit. Specification 362,508 is referred to.
