Description

"Gegenstand der Erfindung ist eine Kühlküvette für Bildwerfer, die Mittel aufweist, um die Temperatur der Kühlflüssigkeit auch bei langen Vorführungen in solchen Grenzen zu halten, daß keine Blasenbildung auftritt. Das Kühlen der Flüssigkeit von Küvetten ist bereits in der Weise durchgeführt worden, daß der Küvettenkörper entweder mit hohlen Kühlrippen versehen wurde, die immer mit"The subject of the invention is a cooling cuvette for projectors, which has means around the temperature of the coolant, even with long presentations within such limits to keep that no blistering occurs. The cooling of the liquid from cuvettes is has already been carried out in such a way that the cuvette body is either hollow Cooling fins were always provided with

ίο der Flüssigkeit der Küvette angefüllt sind und von der Außenluft gekühlt werden, oder daß dem Inhalt der Küvette während des Gebrauches dauernd Frischwasser zugeleitet wurde. Im ersteren Falle erzielte man überhaupt keine durchgreifende Kühlung und im letzteren konnte der Nachteil nicht vermieden werden, daß sich an den Abschlußscheiben der Küvette Luftbläschen ansetzten, wodurch bekanntlich eine hohe Lichtschwächung eintritt. ίο the liquid in the cuvette is full and cooled by the outside air, or that the contents of the cuvette during the Fresh water has been continuously supplied to use. In the former case one achieved at all no thorough cooling and in the latter the disadvantage could not be avoided be that on the cover plates of the cuvette air bubbles settled, whereby as is known, a high level of light attenuation occurs.

Beim Gegenstand der Erfindung befindet sich die Flüssigkeit, die den Inhalt' der Küvette kühlen soll, in an sich bekannter Weise in einem besonderen Behälter, der nach der Erfindung in Gestalt einer Kühl-■ schlange in einen oberen Ausbau der Küvette,· den "die Lichtstrahlen nicht treffen, eingelagert ist. In diesen Raum steigt die erwärmte Flüssigkeit der Küvette auf und wird dauernd von dem durch die Kühlschlange laufenden Frischwasser abgekühlt. Die Abkühlung ist so bedeutend, daß nur geringe Mengen Frischwasser erforderlich sind. Eine Erhitzung der Küvettenflüssigkeit bis zu dem Grade, wo Dampfbläschenbildung eintritt, ist auf diese Weise als ausgeschlossen zu betrachten. When the subject of the invention is the liquid, the content of 'the The cuvette should cool in a known manner in a special container that according to the invention in the form of a cooling coil in an upper extension of the cuvette, which "the rays of light do not hit, is stored. The heated one rises into this room Liquid in the cuvette and is constantly from the running through the cooling coil Fresh water cooled. The cooling is so important that only small amounts of fresh water are required. A heating of the cuvette liquid to the point where vapor bubble formation occurs to be considered excluded in this way.

In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar zeigt die Abb. 1 eine Vorderansicht der Küvette und Abb. 2 eine Seitenansicht im teilweisen Schnitt, α ist der obere, auch mit Flüssigkeit angefüllte Ausbau der Küvette und b die hierin eingelagerte Kühlschlange.The drawing shows an exemplary embodiment of the subject matter of the invention, namely Fig. 1 shows a front view of the cuvette and Fig. 2 shows a side view in partial section, α is the upper, also filled with liquid, extension of the cuvette and b is the cooling coil stored therein .
