To generate the excitation voltage, the frequency of which should preferably not be less than 1000 Hz, ice. separate oscillator, a »B. a hearing earpiece, serve that its supply voltages, aua the receiver receives »Der aus the "two electrodes 17 and 27 and those in between Layer existing probe then represents the capacity of the oscillator circuit

Without special measures this capacity can be considerable and so tHe the currents in the resonant circuit and therefore the occurring "losses VIm be quite large * reduce zn the losses in the disk, it is recommended that the Phoephorsohicht 23 the Weehselfeld

casual: it is / can be reached * because it is only arranged at these points, but even better because "if one of the lead electrodes, appropriately layer 27 , is substantially limited", which at the same time reduces the capacity.

ELg. 3 shows a rope and a scale disk ait openings in the mask 21 in the form of rectangles. 29 _r which aarkieren the location of the transmitting stations, lettering 3t and strips 33 ^ on which the wavelengths 35 are marked. The shape of the electrode layer 27 is shown in dashed lines; As can be seen from the figure, this layer is only behind the pike corners 29, lettering. 31 etc. "attached so that the surface ϋίατ electrode and the capacitance of the Sehichtensystens 15 is considerably smaller. The files of the layer 27 are electrically connected to each other by means of narrow extensions 37 and can

if different wavebands are marked on the scale are «the parts of the Electrode 27 insulated from one another and connected to contacts of the Wave switch be connected in order to ensure that only the waveband marking then used is illuminated * If desired, by using different phosphors intended for the markings Parts are illuminated in different colors.

You between aen. Electrodes 17 and 2? Occurring tensions are expediently of the order of magnitude of 200 to 500 7. With regard to the safety of the operator, it is desirable to mount the dial 3 in the box in such a way that its rear side is from the outside

is not accessible. This is the case shown reached by means of the glass pane 14 which also protects the pointer 13 »

In contrast to FIG. 2, the cover layer 21 can lie directly on the layer 17 which acts as an electrode and be electrically connected to it. ”The eaeksehicht then used is electrically conductive and increases the conductivity of layer 17
