Abstract
443,172. Adjusting wireless apparatus. IDEAL WERKE AKT.-GES. FUR DRAHTLOSE TELEPHONIE, Hohensch÷nhausen, Berlin. Nov. 28, 1934, No. 34173. Convention date, Dec. 9, 1933. [Class 37] A tuning indicator for wireless receivers comprises a fully visible scale 1 on which the station names are arranged in order of countries and in order of wavelengths, an indicator 3 for each country division being actuated from a common drive, or a single indicator movable from division to division may be employed, or each indicator may be separately actuated. The country names are marked on the indicator, which may be arranged behind a transparent scale. The country stations on which the receiver is operating may be illuminated more than others or coloured differently, and when one indicator is employed the source of illumination is coupled with the adjustment mechanism. Specification 414,937 is referred to.
