arbeiten, wodurch das Bühnenbild gestört wird.
Um die Betätigung aller Scheinwerfer von einer Zentralstelle aus bewirken zu können. hat man vorgeschlagen, die Scheinwerfer mit Blenden auszurüsten und diese durch Elektromagnete zu betätigen. Diese Einrichtung löst die Aufgabe nur unvollständig, denn es ist dabei nur möglich, die Blenden entweder ganz zu schliessen oder ganz zu offnen.
Nach vorliegender Erfindung geschieht die Bewegung der Abdeckscheiben durch regelbare und urnsteuerbare Elektromotoren, die natürlich alle von einer Zentralstelle aus bedient werden können. Die Erfindung bietet den Vorteil, dass man die Ahdeckcbeiben nach beiden Richtungen mit jeder gewünschten Geschwindigkeit bewegen und sie m jeder beliebigen Zwischenstellung stehen lassen kann. Man erzielt dadurch bedeutend schönere Lichtetfekte.
Nach der Erfindung ist ferner eine Einrichtung vorgesehen, durch die der Beleuchter die jeweilige Stellung der einzelnen für ihn direkt nicht sichtbaren Abdeckscheiben erkennen kann.
Mit jeder Abdeckscheibe ist ein Gleitkontakt verbunden, der auf einem Widerstandsdraht gleitet.
EMI1.3
instrument h angegeben, dessen Zeigerausschlag durch die nach der jeweiligen Stellung der Ab- deck-scheibe verschiedene Grösse eines durch diese eingeschalteten Widerstandes < beeinflusst wird.
Die Abdeckscheibe selbst kann einfarbig oder mehrfarbig sein, so dass man im letztgenannten
Falle durch eine Verschiebung der Scheibe gewünschte Übergänge von einer Farbe zur andern er- zielen kann.
Bei Anwendung eines geeigneten Umschalters und einer entsprechenden Kupplung ist es miiglich, für mehrere Führungsspindeln d nur einen Elektromotor zu verwenden.

work, which disrupts the scenery.
In order to be able to operate all headlights from a central point. it has been proposed to equip the headlights with screens and to operate them by electromagnets. This device does the job only incompletely, because it is only possible either to close the panels completely or to open them completely.
According to the present invention, the movement of the cover plates is done by controllable and reversible electric motors, which of course can all be operated from a central point. The invention offers the advantage that you can move the Ahdeckcbeiben in both directions at any desired speed and they can be left in any intermediate position. This results in significantly more beautiful light effects.
According to the invention, a device is also provided by means of which the illuminator can recognize the respective position of the individual cover panes which are not directly visible to him.
A sliding contact, which slides on a resistance wire, is connected to each cover plate.
EMI1.3
instrument h, the pointer deflection of which is influenced by the variable size of a resistor <depending on the position of the cover disk.
The cover plate itself can be monochrome or multicolored, so that one in the latter
Fall can achieve desired transitions from one color to another by shifting the disc.
When using a suitable switch and a corresponding coupling, it is possible to use only one electric motor for several guide spindles d.
