Abstract

617,193. Radio receiving apparatus. COOPER, A. H., and EGGLETON, C. W. June 7, 1946, No. 17326. [Class 40 (v)] An interchangeable coil unit for radio or like apparatus is arranged to be inserted longitudinally, being guided by members 4 which locate in corresponding apertures formed in screens 12 internal to the apparatus. The members 4 carry contact studs and are provided with gaps 19 corresponding with the screens 12, so that when fully inserted the unit may be rotated until the contact studs engage fixed contacts 11. Further rotation brings into engagement another set of contacts corresponding to a second waverange. A disc 5 carried on the front of each unit bears tuning scales which co-operate with an annular indicator, the appropriate scale coming into position as the unit is rotated. The indicator is attached to the casing of the apparatus and driven from the tuning means (Fig. 2, not shown); alternatively, each coil unit may carry a separate indicator which is driven by means of a clutch.
