Abstract

469,795. Adjusting wireless apparatus. FABBRICA ITALIANA MAGNETI MARELLI. Dec. 17, 1936, No. 34725. Convention date, Dec. 20, 1935. [Class 37] In map tuning-indicators, the geographical positions 2 of the transmitting stations are connected by lines 7 to index marks 5 arranged in frequency order and these latter index marks co-operate with the receiver tuning indicator 3. Where transmitting stations have two or more wavelengths an index mark 5<1> or 5<11> is associated with the geographical position for each wavelength. The index marks may be formed as light spots, or they can be coloured.
