Definitions
- the invention relates to a device for developing microfilms, in which the exposed film successively passes through various workstations, such as developer bath, fixing bath pre-watering, post-watering and drying, along a horizontally arranged path with the aid of a motor-driven pair of rollers, with a liquid circulation system, each of which has a workstation is designed as a transport container with a liquid supplying vessel and has a feed pipe and a suction pipe, the suction pipe leading the liquid via a liquid pump via pressure pipes to a bath of the assigned work station and there against the horizontally running underside of the film.
- workstations such as developer bath, fixing bath pre-watering, post-watering and drying
- a device for developing microfilms in which the film to be developed passes through a track consisting of guide rollers and the roller track through further guide and deflecting rollers to form a closed path from an endless, driven belt webbing, in particular a reinforced one Chemical-resistant plastic film belt or similar conveyor belt is designed, on which the film to be developed is attached to the inlet into the developer bath and is released from it before winding up the fully developed and dried film.
- the microfilm to be treated runs through the individual baths, with the liquids washing around the microfilm on both sides.
- the conveyor belt is held on a frame with all the rollers, the drive, the unwinding and the reeling bearing for the microfilm and can be inserted and removed with it in the individual baths or work stations.
- This measure allows the development device to be taken apart in a simple manner, so that the individual baths or work stations and also the transport devices can be cleaned or bath liquids can be added.
- the individual bath fluids must be exchanged and the baths cleaned.
- Special containers are required for the removal of used liquids and the fresh and unused liquids are also stored in their own containers.
- microfilms have no perforations for film transport on the longitudinal edges. For these reasons, it is known to pull the film through the baths with the aid of rollers that grasp the film from its front and back.
- a slip acts on the film, i. H. a tangentially directed force, which in particular has an adverse effect on the film layers softened by the various liquids. This can cause damage to the film layers.
- the invention has for its object both to simplify the film guide system within the device and at the same time to transport the film safely and gently through the device as well as to improve and simplify the circuit with respect to the fresh and unused liquid and the used liquid to be discharged in such a way that half the number of transport containers for these chemicals is eliminated.
- Another object of the invention is to reduce the dimensions of the baths of the individual work stations and thus to reduce the consumption of chemicals.
- each bath of a work station has a liquid and film guide body with an H-shaped cross section, the lateral vertical support walls of which are arranged on or slightly above the floor of the bath of the work station and are at a distance from each other that is slightly smaller than the width of the film, with longitudinal and continuous grooves arranged in the vertical support walls for guiding the film above the crossbar and the crossbar with a central bore directed towards the underside of the film surface is provided for the liquid supply, and that the roller pair leading the microfilm through all baths is arranged in the transport direction in front of the baths.
- the liquid and film guide bodies advantageously have a length which is in each case smaller than the length of the baths of the workstations, so that the liquid flowing from the bore onto the crossbar reaches the bottom of the bath and into the feed pipes.
- a crossbar is arranged between the vertical support walls of the liquid and film guide bodies above the film guide grooves.
- the device shown in Figure 1 is located in a housing, not shown, whose front flap releases the vessels 2, 3, 4 and 5 in the open state.
- the vessels 2 and 5 are designed as vessels that can be closed with a screw cap.
- the vessel 2 serves to supply the work station 16 with developer solution and the vessel 3 contains a fixing solution to supply the work station 17.
- the vessels 4 and 5 supply the work stations 18 and 19, which are used for primary and main watering and therefore contain appropriate watering agents.
- Each vessel 2 to 5 is connected to a corresponding intake pipe 10, 11, 12 or 13.
- the suction pipes lead to a liquid pump 14, which has four suction and four pressure chambers.
- the pipes 40, 41, 42 and 43 running on the pressure side of the liquid pump 14 pass through a heater 15, which will be explained in more detail later with reference to FIG. 2.
- the individual workstations 16, 17, 18 and 19 are constructed in principle in the same way, with the exception of an upper crosspiece, which will also be discussed in more detail later, so that it is also sufficient to understand the device if the workstation 16 is described in detail as an example . 3 is used at the same time.
- the entire work stations including the drying station 47 are covered by a removable cover part 1 during the work process.
- a liquid and film guide body 20 is arranged, which has an H-shaped cross section, the vertical supports 24 and 25 of which lie on the floor 26 of the bath of the work station Support 16.
- the distance between the vertical supports 24 and 25 is slightly smaller than the width of the film 31 (see FIG. 3).
- grooves 33 and 34 extending in the longitudinal direction are provided in the vertical supports 24 and 25 above the crosspiece 32.
- the crosspiece 32 is provided with a central bore 35 directed towards the film surface, which is connected to the pressure tube 40.
- the length of the liquid and film guide body 20 is less than the length of the bath of the work station 16, so that the developer solution flowing from the bore 35 onto the crossbar 32 reaches the bottom 26 of the bath and the feed pipe 6, which is connected to the vessel 2 connected is. Since the length of the liquid and film guide bodies is less than the longitudinal extent of the baths, the film between the individual baths is completely exposed, so that the liquid is not carried over from one bath to the subsequent bath.
- the grooves 33 and 34 in the vertical supports 24 and 25 are dimensioned such that the film 31 receives sufficient play.
- the film 31 is guided approximately at a distance of 2 to 3 mm above the crosspiece 32, so that there is an extremely small space through which liquid flows. This brings the underside of the film into intensive contact with the developer solution.
- a transverse web 36 and 37 are located in the work stations 16 and 19 between the vertical supports 24 and 25 of the liquid and film guide bodies 20 and 23 above the film guide grooves 33 and 34.
- the rollers 45 and 46 are driven by gears 49 and 50 by means of a transmission 51 from the motor 52.
- the transmission 51 also actuates the film winding roller 53 and two drying rollers 54 and 55 via its gears 53 and two drying rollers 54 and 55 via its gears 56 and 57. No drive is required for the film reel 58, since the pair of rollers 45 and 46 remove the film from the Roll 58 rolls and ' pushes it through the film guide grooves 33 and 34.
- the heater 15 consists of an electric heating element 39, which is surrounded by the pressure pipes 40, 41, 42 and 43 at a distance. This space is filled with quartz sand, which is enclosed by the jacket 35.
- the pressure pipe 40 is connected to a temperature controller 44 which controls the heating power of the electric heating element 39 with the aid of an electronic circuit.
- the liquid pump 14 and the heater 15 are switched on, so that a continuous liquid circulation is started before the film 31 is in the device.
- the motor 52 is actuated and the film 31 is fed to the rollers 45 and 46, which grip it and guide it through the film guide grooves 33 and 34 of all liquid and film guide bodies 20 to 23. If the film reaches the liquid and film guide body 20, it cuts through the liquid flow, the upper transverse web 36 ensuring that a liquid space is also formed above the film. Since the film 31 has sufficient play in the grooves 33 and 34, the capillary action ensures that an adequate flow and thus renewal of the liquid is also formed. As already mentioned at the beginning, it is only necessary to provide upper transverse webs 36 and 37 if the upper film side is to be wetted. In the other cases, the upper crossbars can therefore be omitted.
- Vessels 2 to 5 perform three different functions. So they serve once for the transport of the still fresh liquid, form a storage tank within the device, which is located in the circuit of the respective liquid and also serve for the removal of the used liquid. In Ver half of the number of vessels is therefore eliminated in comparison to the previously known devices. A laborious cleaning of the storage tanks is no longer necessary. Within the workstations there is the advantage that they can be dimensioned relatively small because of the intense flow, while still having a constant effect on the film. Overall, there is the advantage that the device according to the invention can be used not only in the usual laboratories, but also in other rooms that do not have any special facilities, as are common for laboratories, since no pollution of the environment by cleaning processes Device can occur.

Description
Die Erfindung betrifft eine Vorrichtung zum Entwickeln von Mikrofilmen, bei welcher der belichtete Film nacheinander verschiedene Arbeitsstationen wie Entwicklerbad, Fixierbad Vorwässerung, Nachwässerung und Trocknung, entlang einer horizontal angeordneten Bahn mit Hilfe eines motorisch angetriebenen Rollenpaares durchläuft, mit einem Flüssigkeitsumlaufsystem, bei dem jedes eine Arbeitsstation mit einer Flüssigkeit versorgende Gefäß als Transportbehälter ausgebildet ist und ein Zuleitungsrohr und ein Ansaugrohr aufweist, wobei das Ansaugrohr die Flüssigkeit über eine Flüssigkeitspumpe über Druckrohre zu einem Bad der zugeordneten Arbeitsstation und dort gegen die horizontal verlaufende Filmunterseite führt.The invention relates to a device for developing microfilms, in which the exposed film successively passes through various workstations, such as developer bath, fixing bath pre-watering, post-watering and drying, along a horizontally arranged path with the aid of a motor-driven pair of rollers, with a liquid circulation system, each of which has a workstation is designed as a transport container with a liquid supplying vessel and has a feed pipe and a suction pipe, the suction pipe leading the liquid via a liquid pump via pressure pipes to a bath of the assigned work station and there against the horizontally running underside of the film.
Aus der DE-PS 22 18 369 ist eine Vorrichtung zum Entwickeln von Mikrofilmen bekannt, bei der der zu entwickelnde Film eine aus Führungsrollen bestehende Bahn durchläuft und die Rollenbahn durch weitere Führungsund Umlenkrollen zu einer geschlossenen Bahn aus einem endlosen, angetriebenen Gurtband, einem insbesondere verstärkten chemiekalienbeständigen Kunststoff-Folienband oder dergleichen Transportband ausgestaltet ist, an dem der zu entwickelnde Film am Einlauf in das Entwicklerbad befestigt und von diesem vor dem Aufspulen des fertig entwickelten und getrockneten Films wieder gelöst wird. Der zu behandelnde Mikrofilm durchläuft dabei die einzelnen Bäder, wobei die Flüssigkeiten den Mikrofilm beidseitig umspülen. Das Transporband ist mit allen Rollen, dem Antrieb, der Abspul- und der Aufspullagerung für den Mikrofilm auf einem Gestell gehaltert und kann mit diesem in die einzelnen Bäder bzw. Arbeitsstationen eingesetzt und wieder abgenommen werden. Durch diese Maßnahme läßt sich die Entwicklungsvorrichtung in einfacher Weise auseinandernehmen, so daß die einzelnen Bäder bzw. Arbeitsstationen und auch die Transporteinrichtungen gereinigt bzw. Badflüssigkeiten zugegeben werden können. Neben der Tatsache, daß die Konstruktionen des Rollensystems aufwendig ist und eine besondere Reinigung nach den Arbeitsabläufen erforderlich ist, müssen die einzelnen Badflüssigkeiten ausgetauscht und die Bäder gereinigt werden. Für die Abführung verbrauchter Flüssigkeiten sind besondere Gefäße erforderlich und entsprechend werden auch die frischen und unverbrauchten Flüssigkeiten in eigenen Behältern aufbewahrt.From DE-PS 22 18 369 a device for developing microfilms is known, in which the film to be developed passes through a track consisting of guide rollers and the roller track through further guide and deflecting rollers to form a closed path from an endless, driven belt webbing, in particular a reinforced one Chemical-resistant plastic film belt or similar conveyor belt is designed, on which the film to be developed is attached to the inlet into the developer bath and is released from it before winding up the fully developed and dried film. The microfilm to be treated runs through the individual baths, with the liquids washing around the microfilm on both sides. The conveyor belt is held on a frame with all the rollers, the drive, the unwinding and the reeling bearing for the microfilm and can be inserted and removed with it in the individual baths or work stations. This measure allows the development device to be taken apart in a simple manner, so that the individual baths or work stations and also the transport devices can be cleaned or bath liquids can be added. In addition to the fact that the construction of the roller system is complex and a special cleaning is required according to the work processes, the individual bath fluids must be exchanged and the baths cleaned. Special containers are required for the removal of used liquids and the fresh and unused liquids are also stored in their own containers.
Aus der US-PS 4,101,919 ist eine Vorrichtung zum Entwickeln belichteter Filme bekannt, welche hintereinanderliegende Flüssigkeitsbäder aufweist, wobei sich zwischen jedem Bad jeweils zwei Rollenpaare mit den erforderlichen Antrieben und den Lagerungen befinden. Neben diesen aufwendigen Mitteln sind jedoch noch weitere nachteilige Wirkungen vorhanden, welche im folgenden beschrieben werden.A device for developing exposed films is known from US Pat. No. 4,101,919, which has liquid baths located one behind the other, with two pairs of rollers with the required drives and the bearings being located between each bath. In addition to these expensive means, however, there are other adverse effects, which are described below.
Mikrofilme weisen aus technischen Gründen an den Längsrändern keine Perforationen für den Filmtransport auf. Aus diesen Gründen ist es bekannt, den Film mit Hilfe von Walzen, die den Film von seiner Vorderund Rückseite erfassen, durch die Bäder zu ziehen.For technical reasons, microfilms have no perforations for film transport on the longitudinal edges. For these reasons, it is known to pull the film through the baths with the aid of rollers that grasp the film from its front and back.
Bei jeder Transportwalze wirkt auf den Film ein Schlupf, d. h. eine tangential gerichtete Kraft, welche insbesondere auf die durch die verschiedenen Flüssigkeiten aufgeweichten Filmschichten nachteilig wirkt. Dies kann Beschädigungen der Filmschichten hervorrufen.With each transport roller, a slip acts on the film, i. H. a tangentially directed force, which in particular has an adverse effect on the film layers softened by the various liquids. This can cause damage to the film layers.
Der Erfindung liegt die Aufgabe zugrunde, sowohl das Filmführungssystem innerhalb der Vorrichtung zu vereinfachen und gleichzeig den Film sicher und schonend durch die Vorrichtung zu transportieren als auch den Kreislauf bezüglich der frischen und unverbrauchten Flüssigkeit sowie der abzuführenden verbrauchten Flüssigkeit derart zu verbessern und zu vereinfachen, daß die halbe Anzahl der Transportgefäße für diese Chemikalien entfällt.The invention has for its object both to simplify the film guide system within the device and at the same time to transport the film safely and gently through the device as well as to improve and simplify the circuit with respect to the fresh and unused liquid and the used liquid to be discharged in such a way that half the number of transport containers for these chemicals is eliminated.
Eine weitere Aufgabe der Erfindung besteht darin, die Dimensionen der Bäder der einzelnen Arbeitsstationen zu verkleinern und damit den Chemikalienverbrauch zu verringern.Another object of the invention is to reduce the dimensions of the baths of the individual work stations and thus to reduce the consumption of chemicals.
Die Lösung dieser Aufgabe besteht gemäß der Erfindung darin, daß sich an die Flüssigkeitspumpe eine Heizung anschließt, daß jedes Bad einer Arbeitsstation einen Flüssigkeits- und Filmführungskörper mit H-förmigem Querschnitt aufweist, dessen seitliche Vertikalstützwände an oder geringfügig über dem Boden des Bades der Arbeitsstation angeordnet sind, und einen Abstand voneinander haben, der geringfügig kleiner als die Breite des Filmes ist, wobei zur Filmführung oberhalb des Quersteges in Längsrichtung verlaufende und durchgehende Nuten in den Vertikalstützwänden angeordnet sind und der Quersteg mit einer zentralen - auf die Unterseite der Filmfläche gerichteten - Bohrung für die Flüssigkeitszuführung versehen ist, und daß das den Mikrofilm durch sämtlich Bäder führende Rollenpaar in Transportrichtung vor den Bädern angeordnet ist.The solution to this problem is according to the invention that a heater is connected to the liquid pump, that each bath of a work station has a liquid and film guide body with an H-shaped cross section, the lateral vertical support walls of which are arranged on or slightly above the floor of the bath of the work station and are at a distance from each other that is slightly smaller than the width of the film, with longitudinal and continuous grooves arranged in the vertical support walls for guiding the film above the crossbar and the crossbar with a central bore directed towards the underside of the film surface is provided for the liquid supply, and that the roller pair leading the microfilm through all baths is arranged in the transport direction in front of the baths.
Die Flüssigkeits- und Filmführungskörper weisen vorteilhaft eine Länge auf, welche jeweils kleiner als die Länge der Bäder der Arbeitsstationen ist, so daß die aus der Bohrung auf den Quersteg strömende Flüssigkeit auf den Boden des Bades und in die Zuleitungsrohre gelangt.The liquid and film guide bodies advantageously have a length which is in each case smaller than the length of the baths of the workstations, so that the liquid flowing from the bore onto the crossbar reaches the bottom of the bath and into the feed pipes.
Zwischen den Vertikalstützwänden der Flüssigkeits- und Filmführungskörper oberhalb der Filmführungsnuten ist jeweils ein Quersteg angeordnet.A crossbar is arranged between the vertical support walls of the liquid and film guide bodies above the film guide grooves.
Die Erfindung wird anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. Hierbei zeigen :
Figur 1 eine schematische Darstellung des Flüssigkeitsumlaufs innerhalb der Vorrichtung mit ihren einzelnen Arbeitsstationen ;- Figur 2 einen Querschnitt durch die Heizungsvorrichtung und
- Figur 3 eine geringfügig vergrößerte Darstellung eines Flüssigkeitsund Filmführungskörpers.
- Figure 1 is a schematic representation of the liquid circulation within the device with its individual work stations;
- Figure 2 shows a cross section through the heating device and
- Figure 3 is a slightly enlarged representation liquid and film guide body.
Die in Figur 1 dargestellte Vorrichtung befindet sich in einem nicht näher dargestellten Gehäuse, dessen vordere Klappe im geöffneten Zustand die Gefäße 2, 3, 4 und 5 freigibt. Die Gefäße 2 und 5 sind als mit einem Schraubdeckel verschließbare Gefäße ausgebildet. Das Gefäß 2 dient zur Versorgung der Arbeitsstation 16 mit Entwicklerlösung und das Gefäß 3 enthält eine Fixierlösung zur Versorgung der Arbeisstation 17. Die Gefäße 4 und 5 versorgen die Arbeitsstationen 18 und 19, welche zur Vor- und Hauptwässerung dienen und daher entsprechende Wässerungsmittel enthalten. Jedes Gefäß 2 bis 5 ist mit einem entsprechenden Ansaugrohr 10, 11, 12 bzw. 13 verbunden. Die Ansaugrohre führen zu einer Flüssigkeitspumpe 14, welche vier Ansaug- und vier Druckkammern aufweist. Die auf der Druckseite der Flüssigkeitspumpe 14 verlaufende Rohre 40, 41, 42 und 43 durchlaufen eine Heizung 15, welche später anhand der Fig. 2 noch näher erläutert wird. Die einzelnen Arbeitsstationen 16, 17, 18 und 19 sind im Prinzip gleich aufgebaut mit Ausnahme eines oberen Quersteges, auf den ebenfalls später noch näher eingegangen wird, so daß es auch zum Verständnis der Vorrichtung ausreichend ist, wenn die Arbeitsstation 16 als Beispiel ausführlich beschrieben wird. Hierzu wird gleichzeitig die Fig. 3 herangezogen. Die gesamten Arbeitsstationen einschließlich der Trockenstation 47 sind von einem abnehmbaren Deckelteil 1 während des Arbeitsvorganges abgedeckt. Innerhalb des Bades der Arbeitsstation 16 (ebenso wie innerhalb der Bäder der Arbeitsstationen 17, 18 19) ist ein Flüssigkeits- und Filmführungskörper 20 angeordnet, der einen H-förmigen Querschnitt aufweist, dessen Vertikalstützen 24 und 25 sich auf dem Boden 26 des Bades der Arbeitsstation 16 abstützen.The device shown in Figure 1 is located in a housing, not shown, whose front flap releases the
Der Abstand der Vertikalstützen 24 und 25 ist gerinfügig kleiner als die Breite des Filmes 31 (siehe hierzu Fig. 3). Zur Filmführung sind in den Vertikalstützen 24 und 25 oberhalb des Quersteges 32 in Längsrichtung verlaufende Nuten 33 und 34 vorgesehen. Der Quersteg 32 ist mit einer zentralen und auf die Filmfäche gerichtete Bohrung 35 versehen, welche mit dem Druckrohr 40 verbunden ist. Die Länge des Flüssigkeits- und Filmführungskörpers 20 ist geringer als die Länge des Bades der Arbeitsstation 16, so daß die aus der Bohrung 35 auf den Quersteg 32 strömende Entwicklerlösung auf den Boden 26 des Bades und in das Zuleitungsrohr 6 gelangt, welches mit dem Gefäß 2 verbunden ist. Da die Länge der Flüssigkeits- und Filmführungskörper kleiner ist als die Längsausdehnung der Bäder, liegt der Film zwischen den einzelnen Bädern vollständig frei, so daß auch keine Verschleppung der Flüssigkeit von einem Bad zum sich anschließenden Bad erfolgt. Die Nuten 33 und 34 in den Vertikalstützen 24 und 25 sind derartig dimensioniert, daß der Film 31 ein ausreichendes Spiel erhält. Der Film 31 wird etwa in einem Abstand von 2 bis 3 mm oberhalb des Quersteges 32 geführt, so daß ein äußerst geringer mit Flüssigkeit durchströmter Raum vorhanden ist. Hierdurch wird die Filmunterseite mit der Entwicklerlösung intensiv in Kontakt gebracht.The distance between the vertical supports 24 and 25 is slightly smaller than the width of the film 31 (see FIG. 3). To guide the film,
In Sonderfällen ist es auch erforderlich, die Oberseite des Filmes mit Entwicklerlösung und einer Wässerungsflüssigkeit zu kontaktieren. Aus diesen Gründen befinden sich in den Arbeitsstationen 16 und 19 zwischen den Vertikalstützen 24 und 25 der Flüssigkeits- und Filmführungskörper 20 und 23 oberhalb der Filmführungsnuten 33 und 34 jeweils ein Quersteg 36 bzw. 37. Vor der ersten Arbeitsstation 16 ist ein motorisch angetriebenes Rollenpaar 45 und 46 für den Filmtransport vorgesehen. Die Rollen-45 und 46 werden über Zahnräder 49 und 50 mit Hilfe einer Transmission 51 von dem Motor 52 angetrieben. Die Transmission 51 betätigt ferner die Filmaufspulrolle 53 sowie zwei Trockenwalzen 54 und 55 über ihre Zahnräder 53 sowie zwei Trockenwalzen 54 und 55 über ihre Zahnräder 56 und 57. Für die Filmspule 58 ist kein Antrieb erforderlich, da das Rollenpaar 45 und 46 den Film von der Rolle 58 abrollt und' diesen durch die Filmführungsnuten 33 und 34 schiebt.In special cases it is also necessary to contact the top of the film with developer solution and a washing liquid. For these reasons, a
Die Heizung 15 besteht aus einem elektrischen Heizstab 39, der von den Druckrohren 40, 41, 42 und 43 in einem Abstand umgeben ist. Dieser Raum ist mit Quarzsand ausgefüllt, der von dem Mantel 35 eingeschlossen ist. Das Druckrohr 40 ist an einen Temperaturregler 44 angeschlossen, der mit Hilfe einer elektronischen Schaltung die Heizleistung des elektrischen Heizstabes 39 regelt.The
Zur Bestätigung der Vorrichtung werden die Flüssigkeitspumpe 14 und die Heizung 15 eingeschaltet, so daß bereits ein kontinuierlicher Flüssigkeitsumlauf in Gang gesetzt wird, bevor sich der Film 31 in der Vorrichtung befindet. Sobald die erforderliche Temperierung der Flüssigkeiten erreicht ist, wird der Motor 52 betätigt und der Film 31 den Rollen 45 und 46 zugeführt, welche diesen erfassen und ihn durch die Filmführungsnuten 33 und 34 sämtlicher Flüssigkeits- und Filmführungskörper 20 bis 23 leiten. Gelangt der Film in den Flüssigkeits- und Filmführungskörper 20 so durchschneidet er den Flüssigkeitsstrom, wobei der obere Quersteg 36 dafür sorgt, daß auch oberhalb des Filmes ein Flüssigkeitsraum ausgebildet wird. Da der Film 31 in den Nuten 33 und 34 ein ausreichendes Spiel aufweist, sorgt die Kapillarwirkung dafür, daß sich auch eine aureichende Strömung und damit Erneuerung der Flüssigkeit ausbildet. Wie bereits eingangs erwähnt, ist es erforderlich, lediglich dann obere Querstege 36 und 37 vorzusehen, wenn die obere Filmseite benetzt werden soll. In den anderen Fällen können daher die oberen Querstege entfallen.To confirm the device, the liquid pump 14 and the
Die Gefäße 2 bis 5 erfüllen drei unterschiedliche Funktionen. So dienen sie einmal für den Transport der noch frischen Flüssigkeit, bilden innerhalb der Vorrichtung einen Vorratstank, der sich innerhalb des Kreislaufes der jeweiligen Flüssigkeit befindet und dienen ferner auch für den Abtransport der verbrauchten Flüssigkeit. Im Vergleich zu den bisher bekannten Einrichtungen entfällt daher die halbe Anzahl der Gefäße. Eine umständliche Reinigung der Vorratstanks ist nicht mehr erforderlich. Innerhalb der Arbeitsstationen ergibt sich der Vorteil, daß diese wegen des intensiven Strömungslaufes relativ klein dimensioniert werden können, wobei dennoch eine gleichbleibende Wirkung auf den Film erzielt wird. Damit ergibt sich insgesamt der Vorteil, daß die Vorrichtung nach der Erfindung nicht nur in den üblichen Labors verwendet werden kann, sondern auch in anderen Räumen, die keine speziellen Einrichtungen aufweisen, wie sie für Labors üblich sind, da keine Verschmutzung der Umgebung durch Reinigungsprozesse der Vorrichtung auftreten können.Vessels 2 to 5 perform three different functions. So they serve once for the transport of the still fresh liquid, form a storage tank within the device, which is located in the circuit of the respective liquid and also serve for the removal of the used liquid. In Ver half of the number of vessels is therefore eliminated in comparison to the previously known devices. A laborious cleaning of the storage tanks is no longer necessary. Within the workstations there is the advantage that they can be dimensioned relatively small because of the intense flow, while still having a constant effect on the film. Overall, there is the advantage that the device according to the invention can be used not only in the usual laboratories, but also in other rooms that do not have any special facilities, as are common for laboratories, since no pollution of the environment by cleaning processes Device can occur.
