Abstract

465,442. Adjusting wireless apparatus. MINERVA-RADIO W. WOHLEBER & CO. June 29, 1936, Nos. 18053 and 18054. Convention dates, June 27, 1935 and July 16, 1935. [Class 37] A tuning - indicator comprises concentric drums 1, 2, the drum 1 being under the control of the wavechange switch and carrying station names in tabular form corresponding to each range, and the other drum 2, provided with index apertures 5, being connected with the tuning condenser 3. Instead of drums, endless belts passing over rollers can be employed. The belts may have perforations engaged by teeth on the driving mechanism, and they need not be parallel along their entire length. The indications are obtained by a magnifying optical device.
