Description
Bei dem Betrieb von Kerrzellen kommt es häufig vor, daß sich infolge von Durchschlägen im Spalt zwischen den beiden Elektroden Zersetzungsprodukte in Form von kleinen Kohleteilchen festsetzen. Es ist dann erforderlich, den Spalt zu reinigen. Bei den bekannten Konstruktionen der Kerrzellenküvetten werden zu diesem Zweck die Stirnseiten, die aus besonderem optischen Glas hergestellt werden, lösbar angeordnet, indem sie lediglich an die Deckplatten angekittet werden. Bei der Reinigung des Spaltes werden diese Stirnseiten abgenommen. Wenn nach der Reinigung die Stirnseiten wieder angekittet werden, so muß darauf geachtet werden, daß sie spannungsfrei befestigt werden und daß der Abstand der Elektroden erhalten bleibt, was natürlich mit besonderen Schwierigkeiten verbunden ist.In the operation of Kerr cells it often happens that as a result of breakdowns settle decomposition products in the form of small carbon particles in the gap between the two electrodes. It is then necessary to clean the gap. In the known constructions of Kerr cell cuvettes, the end faces, which are made of special optical glass, detachably arranged by merely cemented to the cover plates. When cleaning the gap, these Front sides removed. If the front sides are cemented again after cleaning , care must be taken that they are attached tension-free and that the distance between the electrodes is maintained, which of course presents particular difficulties connected is.
ao Das Wesen der Erfindung besteht darin, in der Stirnseite der Küvette Öffnungen anzubringen, die die Reinigung des Spaltes ermöglichen, ohne daß der Rahmen auseinandergenommen wird. Die Öffnungen werden zweckmäßig mit einem Pfropfen abgeschlossen. Diese Einrichtung hat den Vorteil, daß die Reinigung ohne Zeitverlust an Ort und Stelle vorgenommen werden kann und ohne daß die einmal vorhandene genaue Einstellung der Elektroden geändert wird.ao The essence of the invention is to make openings in the face of the cuvette, which allow the gap to be cleaned without dismantling the frame will. The openings are expediently closed with a plug. This device has the advantage that cleaning can be done on the spot without wasting time can be made and without the once existing exact setting of the Electrodes is changed.
Die Erfindung ist beispielsweise in der Abbildung dargestellt.The invention is shown for example in the figure.
In einem Steatitrahmen α befinden sich die beiden Zellenelektroden & und d. Die Elektroden sind mit den Schraubend und /, die auch als Kontaktzuleitungen ausgebildet werden können, gehaltert. Erfindungsgemäß befindet sich in dem Rahmen a eine Öffnung ^ und in der Elektrode b eine Öffnung h: Die Öffnung g ist mit dem Metallpfropfen i geschlossen. Die Öffnung Ji hat vorzugsweise einen trapezförmigen Querschnitt. Soll der Spalt k gereinigt werden, so wird der Verschluß i abgenommen und der Spalt kann ohne Schwierigkeit in seiner Längsrichtung gereinigt werden.The two cell electrodes & and d are located in a steatite frame α. The electrodes are held with the screw and / which can also be designed as contact leads. According to the invention there is an opening ^ in the frame a and an opening h in the electrode b : the opening g is closed with the metal plug i . The opening Ji preferably has a trapezoidal cross section. If the gap k is to be cleaned, the closure i is removed and the gap can be cleaned in its longitudinal direction without difficulty.
Es können auch mehrere Öffnungen im Rahmen α bzw. in der Elektrode b vorgesehen, werden.Several openings can also be provided in the frame α or in the electrode b .
