  Polarisierte Nebenuhr. 



   Elektrische Uhren, die von einer   Zentraluhr   betrieben werden, sogenannte sympatische oder Nebenuhren, werden bei Verwendung permanenter Magnete gewöhnlich in der Weise gehaut, dass infolge von wechselnden   Stromstössen   in Spulen, die sich auf dem Magneten befinden, Polarisationsänderungen hervorgerufen werden, so dass der ebenfalls polarisierte Anker sich bewegt und eine Fortschaltung der Uhrzeiger bewirkt. 



   Diese Bauart hat jedoch den Nachteil, dass infolge der Umpolarisierungen eine Schwächung des permanenten Magneten eintritt, oder aber es kommen Remanenzstörungen vor, die ein Vorsagen der Uhren bzw. asynchronen Gang verursachen können. 



   Vorliegende Erfindung vermeidet diese Nachteile dadurch, dass eisenlose Spulen im Felde eines permanenten Magneten beweglich angeordnet sind und bei Stromänderungen

   Zeichnung   zu   ersehe. Zwischen den   Polen   it   und s eines permanenten Magneten 1 befindet sich der auf der Achse 2 drehbar gelagerte Hebel 3, an welchem beispielsweise zwei eisenlose Spulen 4 und 5 befestigt sind. Wird nun in diese beispielsweise hinter-   einandergf'schalteten   Spulen Strom in einer bestimmten Richtung geschickt, so wird die Spule 5 in das zwischen den Polen des Magneten 1 vorhandene Feld hineingezogen.

   herum und   bewirkt mittels eines an sich bekannten Klinkengesperres 6 die Fortschaltung der Uhrzeiger 7 und 8.

   Wird alsdann der Strom in den Spulen 4 und 5 gewendet, so schwingt der   Hebe)   3 mit den an ihm befestigten Spulen in die in Fig. 2 gezeichnete Lage zurück. Unter Umständen kann es auch   zweckmässig sein.   von einer Stromwendung   abzusehen und nur   mit gleichgerichteten   Stromstössen   zn arbeiten. Die Einrichtung ist alsdann so zu treffen,   dass   die Spulen unter Einwirkung ihres Eigengewichts wieder in

  Polarized slave clock.



   When using permanent magnets, electrical clocks that are operated by a central clock, so-called sympathetic or slave clocks, are usually cut in such a way that, as a result of alternating current surges in coils on the magnet, changes in polarization are caused, so that the magnet is also polarized The armature moves and causes the clock hands to advance.



   However, this type of construction has the disadvantage that the permanent magnet is weakened as a result of the polarization changes, or there are remanence disturbances that can cause the clocks to predict or the asynchronous rate.



   The present invention avoids these disadvantages in that ironless coils are movably arranged in the field of a permanent magnet and when the current changes
 EMI1.1
   See drawing. Between the poles it and s of a permanent magnet 1 is the lever 3 rotatably mounted on the axis 2, to which, for example, two ironless coils 4 and 5 are attached. If current is now sent in a specific direction into these coils, which are connected one behind the other, for example, then the coil 5 is drawn into the field present between the poles of the magnet 1.
 EMI1.2
   around and causes the clock hands 7 and 8 to advance by means of a ratchet mechanism 6 known per se.

   If the current in the coils 4 and 5 is then turned, the lifting device 3 with the coils attached to it swings back into the position shown in FIG. Under certain circumstances it can also be useful. Refrain from a commutation and only work with rectified current surges. The device must then be made in such a way that the coils under the effect of their own weight are back in
 EMI1.3
   Switching device for the power supply
