Abstract

473,503. Adjusting wireless apparatus. SACHSENWERK, LICHTUND KRAFTAKT.-GES. Aug. 6, 1936, No. 21659. Convention date, Oct. 26, 1935. [Class 37] A projection indicator comprises apertures 4, 13, 14 in conjunction with lenses 23, 24 arranged to project single station names from one or more columns on to a common part of screen 25. The apertures 13, 14 are formed in a slide 5 controlled by the wavechange switch 8 by means of a cord 7 which is anchored by the screw 12 and adjusted by co-operating members 16a, 16b. Instead of a stop 17 limiting the position of the wavechange switch, the cord 7 can be carried around a cam to give the necessary movement to the slide 5. On a disc carrying the station names, distinctive marks 26 can be projected to indicate the wave range in use, or gramophone reproduction, or the wavelength of the station transmitting. An additional aperture in the slide 5 may be provided for the latter purpose.
