Abstract

265,705. Pattinson, K. F., O'Callaghan, C. T., and Waghorne, W. C. Nov. 19, 1925. Sets, construction of.-A crystal receiving-set comprises a base A, preferably moulded, with a centrally - mounted variable condenser B and a plug and socket C for the reception of a coil of fixed inductance. The detector D and telephone terminals E are arranged round the rim of the base, the earth wire is attached to a terminal F, and the aerial wire to one or other of the terminals G, G' according as series or parallel tuning is required. A removable link H connects the terminals F, G when parallel tuning is employed. The spindle of the variable condenser B rests on a metal support which is connected to one of the coil terminals C.
