Description
<Desc/Clms Page number 1>
Vorrichtung zum Anzeigen der jeweiligen Breite des von einem variablen Filter durchgelassenen
Frequenzbandes, insbesondere für Rundfunkempfänger.

<Desc/Clms Page number 2>
Die Gesamtanordnung kann mit Vorteil derart getroffen werden, dass hinter dem Spalt die die Stationsnamen tragende Skala beweglich ist. Bei entsprechender Übersetzung zwischen dem Bandfilter und den Anzeigeorganen wird es dann direkt auf der Skala ersichtlich, wie bei Vergrösserung der Bandbreite in den Frequenzbereich der benachbarten Station übergegriffen wird. Der die Skala bewegende Abstimmknopf kann mit dem das Bandfilter verstellenden Knopf gleiehaehsig angeordnet werden, um die Übersichtlichkeit der Bedienungsknöpfe nicht zu beeinträchtigen.
Entsprechend der Fig. 2 ist eine gegenläufige Bewegung der beiden Anzeigeorgane dadurch erzielt, dass jedes der beiden sektorförmigen Anzeigeorgane unter Zwischenschaltung von Lenkern 7 und eines Gleitstückes 9. das längs einer Führung 8 verschiebbar ist, mit dem andern Anzeigeorgan verbunden ist. Der Antrieb der ganzen Vorrichtung erfolgt durch den das Filter verstellenden Knopf 10. Das Anzeigeorgan 2 weist einen Ausschnitt J. 7 auf, so dass das dahinter befindliche andere Anzeigeorgan 1 durch diesen Ausschnitt hindurch sichtbar wird.
Eine Skala, welche auf 1 sitzt, erleichtert die Wiedereinstellung der günstigsten Filterstellul1g. Die Anordnung kann aber auch derart erfolgen, dass die Ablesung der gerade eingestellten Bandbreite direkt auf der Stationsskala erfolgt, wofür die Fig. 3 ein Beispiel zeigt.
Nach Fig. 3 kann die Skala 12 als Trommelskala ausgeführt sein. Längs einer Stange 1 :, sind

The overall arrangement can advantageously be made such that the scale bearing the station names is movable behind the gap. With a corresponding translation between the band filter and the display elements, it can be seen directly on the scale how the frequency range of the neighboring station is extended when the bandwidth is increased. The tuning button that moves the scale can be arranged identically with the button that adjusts the band filter, so as not to impair the clarity of the control buttons.
According to FIG. 2, the two display elements move in opposite directions in that each of the two sector-shaped display elements is connected to the other display element with the interposition of links 7 and a slider 9, which is displaceable along a guide 8. The entire device is driven by the button 10 that adjusts the filter. The display element 2 has a cutout J. 7, so that the other display element 1 located behind it becomes visible through this cutout.
A scale on 1 makes it easier to set the most favorable filter setting again. However, the arrangement can also take place in such a way that the reading of the bandwidth just set takes place directly on the station scale, of which FIG. 3 shows an example.
According to Fig. 3, the scale 12 can be designed as a drum scale. Along a rod 1:, are
