Description

Anordnung zur Ausführung des Verfahrens der Aufzeichnung elektrischer Signale mittels elektroosmotischer Zelle . Gegenstand der Erfindung ist eine Einrichtung zur Lichtsteuerung für Schnell- oder Bildschreiber unter Benutzung der im Patent 509944 gekennzeichneten elektroosmotischen Vorrichtung. Diese Vorrichtung gestattet mit Hilfe relativ schwacher intermittierender Ströme bzw. Wechselströme eine praktisch genügend trägheitsfreie Steuerung der durch den elektroosmotischen Effekt bewegten Flüssigkeitssäule. Läßt man die Flüssigkeitssäule im Rhythmus der Steuerfrequenz aus einer Düse austreten, so erhält man auf einem vorbeibewegten Papierstreifen durch Tränkung bzw. Farbreaktion das Abbild der Steuerfrequenz.Arrangement for carrying out the method of recording electrical Signals by means of an electroosmotic cell. The invention relates to a device for light control for high-speed or picture writers using the in the patent 509944 electroosmotic device. This device allows with the help of relatively weak intermittent currents or alternating currents, a practical one sufficient inertia-free control of the moved by the electroosmotic effect Column of liquid. If one leaves the column of liquid in the rhythm of the control frequency emerge from a nozzle, it is obtained on a strip of paper moved past the image of the control frequency through impregnation or color reaction.

Die gleiche elektroosmotische Einrichtung soll nun gemäß vorliegender Erfindung zur Steuerung eines Lichtstrahls benutzt werden. Hierzu wird mit Hilfe einer geeigneten optischen Anordnung das Lichtstrahlenbündel mit seiner Einschnürungsstelle in den Weg der gesteuerten Flüssigkeitssäule verlegt, die das Licht durch Abblendung beeinflussen kann. Eine geeignete Anordnung zeigt die Figur. Die von einer Lichtquelle i ausgehende Strahlung wird durch .eine Blende 2 begrenzt und durch eine Linse 3 in das Röhrchen 6 abgebildet, derart, daß das Licht der Quelle unmittelbar über dem Meniskus der Flüssigkeit liegt. Eine Linse 4 entwirft dann den scharfen Lichtfleck auf der rotierenden Schreibtrommel5. Die Anordnung der elektroosmotischen Zelle 7 entspricht der im Hauptpatent angegebenen. In dem Gefäß 7 befinden sich z. B. eine Tonzelle 8 und Innen-und Außenelektroden 9 bzw. io, über die der Stromkreis des Empfängers 13 niederfrequenzseitig mit Hilfe der Zuleitungeh i i und 12 geschlossen wird. 14 ist das Austrittsrohr der Zelle. Die niederfrequenten Stromstöße, die der Empfänger 13 liefert und die den zu übertragenden Telegraphier- bzw. Bildsignalen entsprechen, bewirken .ein intermittierendes Aufsteigen und Zurücksinken der Flüssigkeitssäule 6, wodurch der Lichtstrahl im gleichen Rhythmus von der Empfangsfläche abgeschnitten bzw. wieder zu ihr hindurchgelassen wird. Die Flüssigkeit kann zu diesem Zweck lichtundurchlässig gefärbt sein.The same electro-osmotic device is now to be used in accordance with the present invention for controlling a light beam. For this purpose, with the aid of a suitable optical arrangement, the light beam bundle is moved with its constriction point in the path of the controlled liquid column, which can influence the light by glare. The figure shows a suitable arrangement. The radiation emanating from a light source i is limited by a diaphragm 2 and imaged into the tube 6 by a lens 3 in such a way that the light from the source lies directly above the meniscus of the liquid. A lens 4 then designs the sharp light spot on the rotating writing drum 5. The arrangement of the electroosmotic cell 7 corresponds to that specified in the main patent. In the vessel 7 are z. B. a sound cell 8 and inner and outer electrodes 9 or io, via which the circuit of the receiver 13 is closed on the low-frequency side with the help of the supply lines ii and 12. 14 is the exit tube of the cell. The low-frequency current surges which the receiver 13 delivers and which correspond to the telegraph or image signals to be transmitted cause an intermittent rise and fall of the liquid column 6, whereby the light beam is cut off from the receiving surface or allowed to pass through it again at the same rhythm. The liquid can be colored opaque for this purpose.
