Description
METROHM A.G., H e r i s a u (Schweiz) Titrierapparat mit einem in einem Zylinder verschiebbaren Kolben.METROHM A.G., H e r i s a u (Switzerland) titration apparatus with an in a cylinder displaceable piston.
Zum Titrieren werden üblicherweise mit einer Massteilung versehene Glasbüretten verwendet, die unten mit einem Hhhn verbunden sind. Das Arbeiten mit diesen Retten ist ziemlich ermüdend und braucht viel Zeit, weil man warten muss, bis alle Flüssigkeitsreste von dem Bürettenwänden ablaufen und dann den Flüssigkeitsstand bei entsprechender, unbequemer Höhenlage des Kopfes ablesen muss. Es sind schon gelegentlich Büretten mit einem in ihrem Inneren verschiebbaren Kolben verwendet worden. Diese sog. Kolbenbüretten wurden nach Art von Injektionspritzen gehandhabt. Da deren Handhabung weder besonders bequem war, noch besondere Vorteile bot, haben diese Kolbenbüretten keine grosse Verbreitung gefunden. For titration, graduation marks are usually provided Used glass burettes connected to a cock at the bottom. Working with Rescuing these is quite tiring and takes a lot of time because you have to wait until all liquid residues run off the burette walls and then the liquid level must read at a corresponding, uncomfortable height of the head. It is already occasionally burettes with a piston that can be displaced inside are used been. These so-called piston burettes were handled like injection syringes. Since their handling was neither particularly convenient nor offered any particular advantages, we have these piston burettes have not found widespread use.
Die vorliegende Neuerung schafft nun einen Titrierapparat mit einem in einem Zylinder verschiebbaren Kolben, der den bisherigen Titrierapparaten hinsichtlich Bequemlichkeit, Raschheit und Genauigkeit weit überlegen ist. Der neue Titrierapparat zeichnet sich dadurch aus, dass der Kolben an dem einen Ende einer Gewindespindel angebracht ist) auf welcher eine mit entsprechendem Innengewinde versehene Trommel sitzt) durch deren Drehung der Kolben innerhalb dem Zylinder verschoben werden kann. The present innovation creates a titration apparatus with a in a cylinder displaceable piston, which the previous titration apparatus with regard to Is far superior to convenience, speed, and accuracy. The new titration apparatus is characterized in that the piston is attached to one end of a threaded spindle is attached) on which a drum provided with a corresponding internal thread seated) the rotation of which can move the piston within the cylinder.
In der beiliegenden Zeichnung ist ein Ausführungsbeispiel des neuen
Titrierapparates dargestellt, welches noch zahlreiche andere wichtige neue Merkmale
aufweist. Es ist:
Der Kolben 3, der z. B. aus dem unter der Marke "Teflon"bekannten Kunststoff besteht, ist am oberen Ende einer vertikalen Gewindespindel 11 angebracht, auf welcher eine mit entsprechendem Innengewinde versehene Trommel 212 sitzt, die mit einem Zahnkranz 13 und einer Skala 14 versehen ist. Die Skala 14 ist durch ein rinder Vorderwand des Gehäuses 1 ausgespartes Fenster 15 sichtbar und arbeitet mit einer festen Ablesemarke 16 zusammen. The piston 3, the z. B. from the known under the brand "Teflon" Consists of plastic, is attached to the upper end of a vertical threaded spindle 11, on which a corresponding internally threaded drum 212 sits, which is provided with a ring gear 13 and a scale 14. The scale 14 is through a cattle front wall of the housing 1 recessed window 15 visible and works with a fixed reading mark 16 together.
Mit 17 und 18 sind zwei gehäusefeste Brücken bezeichnet. die zur Lagerung deS Spindel 11 dienen, die natürlich auch durch den Teflonkolben gehalten wird, der einige dünne, elastische Ringrippen 19 aufweist, die ohne Spiel an der Zylinderinnenwand anliegen. Ferner ist am unteren Ende der Spindel 11 ein Führungsstück 20 befestigt, das zwei sich senkrecht zur Spindel erstreckende Arme 21 aufweist, deren Enden an zwei senkrechten Stangen 22 geführt sind, von denen in Fig. 2 nur die hintere sichtbar ist Die beiden Stangen 22 sind oben an der Brücke 18 befestigt und unten durch eine Traverse 23 miteinander verbunden. Am Führungsstück 20 ist ein Zeiger 24 befestigt, der durch einen Schlitz 25 der Qehlusevorderwand hindurchgreift und mit einer vertikalen Skala 26 zusammenarbeit. Am FUhrungstck 20 ist ferner ein Anschlag 27 vorgesehne, der bei der Auf-und Abbewegung der Spindel 11 die Endschalter 28, bzw. 29 öffnet. With 17 and 18 two bridges fixed to the housing are designated. the for Storage of the spindle 11 are used, which of course are also held by the Teflon piston is, which has some thin, elastic annular ribs 19, which without play on the Make contact with the inner wall of the cylinder. Furthermore, a guide piece is at the lower end of the spindle 11 20 attached, which has two arms 21 extending perpendicular to the spindle, the ends of which are guided on two vertical rods 22, of which only in FIG the rear one is visible. The two rods 22 are attached to the top of the bridge 18 and below by one Traverse 23 connected to one another. On the guide piece 20 a pointer 24 is attached, which through a slot 25 of the Qehlusevorderwand reaches through and with a vertical scale 26 cooperate. At the guide 20 a stop 27 is also provided, which during the up and down movement of the spindle 11 the limit switch 28 or 29 opens.
Mit dem Zahnkranz 13 steht ein Antriebsritzel 30 im Eingriff, das von einem Elektromotor 31 über ein Reduktionsgetriebe 32 angetrieben wird. Das Gestell des Motors 31 und des Getriebes 32, die in der Zeichnung schematisch angedeutet sind, ist über Stangen 33 mit einer Wippe 34 verbunden, die bei 35 am Gehlusedach drehbar gelagert ist. Eine Zugfeder 36 sucht die Wippe im Gegenuhrzeigersinne von Fig. 2 zu verdrehen, wodurch das Ritzel 30 mit dem Zahnkranz 13 in Eingriff gehalten wird. With the ring gear 13 is a drive pinion 30 in engagement, which is driven by an electric motor 31 via a reduction gear 32. The frame of the motor 31 and the transmission 32, which are indicated schematically in the drawing are, is connected via rods 33 to a rocker 34, which is at 35 on the Gehlusedach is rotatably mounted. A tension spring 36 seeks the rocker in the counterclockwise direction from Fig. 2 to rotate, whereby the pinion 30 is held with the ring gear 13 in engagement will.
Es ist ersichtlich, dass mittels des Motors 31 die Trommel 12 in
Drehung versetztwrden kann und dass dadurch die Spindel 11 den Kolben 3 in dem Zylinder
2 aufwärts, bzw. abwärts bewegt. Durch entsprechende Einstellung des Dreiweghahnes
