Abstract
447,559. Adjusting wireless apparatus. IDEAL WERKE AKT.-GES. FUR DRAHTLOSE TELEPHONIE, 97, Grosse Leegestrasse, Hohenschonhausen, Berlin. Feb. 18, 1935, Nos. 5223 and 5224. Convention dates, Feb. 17, 1934 and Aug. 17, 1934. [Class 37] Tuning is effected by movement of a gyratory mass which is set in motion by hand and can continue in motion until a station is tuned in. The mass may drive a generator or itself may comprise a generator, the current delivered energizing a motor to effect tuning. Stepby-step tuning adjustment can be effected by a series of current impulses. The indicating scale pointer can be controlled by the rotatory mass or by the tuning element. The impact on the mass may be given at a remote point, for example, on the dashboard of a motor car set. As shown, a flywheel 2 is carried on shaft 5 coupled to shaft 9 through gearing 6, 7, the shaft 9 being further coupled to the condenser spindle 12 by friction gear 10, 11. The drive to the indicator mav be through a belt and this may be located at a remote point.
