Description

Anordnung zur Wellenmessung bzw. Kontrolle -lnittels- Kristalle. Es sind Wellenkontroll- und -meßanordnungen in der drahtlosen Telegraphie bekannt, bei denen man Kristalle (Quarzkristalle) benutzt, die die Eigenschaft haben, Schwingungen in der Größenordnung der elektrischen Wellen zu geben. Durch entsprechendes Behandeln mittels Abschleifen kann man ganz bestimmte Einzelkristalle erhalten, die für eine ganz bestimmte Wellenlänge eines Meßkreises Resonanz geben. Um nun leichter die Wellen in einem gewissen Bereich zu finden, halt man vorgeschlagen, mehrere Kristalle zu benutzen, die auf wenig voneinander abweichende Weilen geschliffen sind und die beim Durchdrehen des elektrischen Systems, dessen Wellen man beobachten will., durch diesen Bereich nacheinander aufleuchten.Arrangement for wave measurement or control - medium crystals. It wave control and measuring arrangements are known in wireless telegraphy, where crystals (quartz crystals) are used, which have the property of vibrations to give in the order of magnitude of the electric waves. By treating them appropriately by grinding you can get very specific single crystals that are necessary for a give resonance to a very specific wavelength of a measuring circuit. To make the easier now To find waves in a certain area, it is suggested to consider several crystals to use, which are honed to little diverging periods and which when the electrical system is spinning, the waves of which are to be observed illuminate this area one after the other.

Gemäß vorliegender Erfindung werden die von mehreren Kristallen verursachten Indikationen dazu benutzt, eine mit fortlaufender Wellenskala versehene Wellenanzeigevorrichtung zu betätigen. Das kann z. B. in einfacher Weise dadurch geschehen, daß man als Indikatoren kleine Glühlampen benutzt, die je einem Kristall zugeordnet sind und hinter einer matten Glastafel, auf der die Wellenskala eingetragen ist, so angeordnet sind, daß sie die einzelnen Skalenfelder belichten. Wird dann der ganze Wellenbereich durchlaufen, so verdunkelt sich jedesmal die Stelle der Skala, deren zugehöriger Kristall in Resonanz kommt.According to the present invention, those caused by multiple crystals Indications used for this, a wave display device provided with a continuous wave scale to operate. This can be B. done in a simple manner that one as indicators uses small incandescent lamps, each assigned to a crystal and behind one Matt glass panel on which the wave scale is entered are arranged so that they expose the individual scale fields. If the whole waveband is then passed through, so each time the point on the scale is darkened, its associated crystal in Feedback is coming.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Anordnung. A ist die matte Glasplatte, auf der die einzelnen Wellen eingraviert sind, B sind die Glühlampen, die hinter der Glasplatte so angeordnet sind, da.ß je eine Lampe das Feld einer Wellenzahl beleuchtet. jede Lampe ist beispielsweise an eine Spule L angeschlossen, auf welche dasjenige System induziert, dessen Welle beobachtet werden soll. Mit je einer derartigen Anordnung ist ein Kristall K kombiniert. Kommt ein bestimmter Kristall in Resonanz mit dem zu beobachtenden System; so entzieht es dem Lampenkreis -Energie und die Lampe verdunkelt sich. Man kann auf diese Weise an dem Erscheinen des dunklen Striches auf der Skala der Mattscheibe die Welle bestimmen. Durch die Benutzung mehrerer Kristalle in 'Verbindung mit der beschriebenen Anzeigevorrichtung läßt sich das Aufsuchen der Welle wesentlich erleichtern.The drawing illustrates an embodiment of the arrangement. A is the matte glass plate on which the individual waves are engraved, B are the incandescent lamps, which are arranged behind the glass plate in such a way that one lamp each illuminates the field of a wavenumber. for example, each lamp is connected to a coil L connected to which the system induces whose wave is observed shall be. A crystal K is combined with such an arrangement. Comes a particular crystal in resonance with the system under observation; so withdraws it energizes the lamp circle and the lamp darkens. You can this way determine the wave from the appearance of the dark line on the scale of the focusing screen. By using several crystals in conjunction with the display device described the search for the shaft can be made much easier.
