KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung' betrifft ein Verfahren und eine Vorrichtung, um die Zeit zu messen, welche eine gerinnende Flüssigkeit bis zu ihrem Gerinnen gebraucht. Um diesen Zeitpunkt mit möglichster Genauigkeit festzustellen, wird dem Erfindungsgedanken zufolge ein membranbildendes Organ, z. B. Kapillarrohr o. dgl., aus geeignetem Material abwechselnd mit der Oberfläche der zu prüfenden Flüssigkeit zur Berührung gebracht und wieder herausgezogen. Tritt das Gerinnen ein, so bildet sich beim Heraustreten des Rohres aus der Flüssigkeit ein Faden zwischen der Oberfläche derselben und der Flüssigkeitsmembran, die an der unteren Mündung des Kapillarrohres o. dgl. gebildet wird. Eine Vorrichtung, welche diese Meßmethode ermöglicht, ist auf der Zeichnung schematisch dargestellt.The invention relates to a method and a device to measure the time, which needs a coagulating liquid to coagulate. At this point in time with Determine the greatest possible accuracy, according to the idea of the invention, a membrane-forming Organ, e.g. B. capillary tube o. The like., Made of suitable material alternating with the surface brought into contact with the liquid to be tested and pulled out again. If coagulation occurs, it forms at the Stepping out of the tube from the liquid a thread between the surface of the same and the liquid membrane formed at the lower mouth of the capillary tube or the like will. A device which enables this measuring method is on the drawing shown schematically.
Dieselbe besteht im wesentlichen aus einem Hebel a, welcher um einen Punkt b schwenkbar gelagert ist. An seinem einen Ende trägt der Hebel ein unten offenes Kapillarrohr c, welches in der unteren Lage des Hebels die zu prüfende Flüssigkeit eben berührt, welche in einem schalenförmigen Gefäß d sich befindet.The same consists essentially of a lever a, which is mounted pivotably about a point b. At one end, the lever carries a capillary tube c open at the bottom, which in the lower position of the lever just touches the liquid to be tested, which is located in a bowl-shaped vessel d .
Das Auf- ■ und Abwärtsbewegen des Röhrchens c kann sowohl von Hand als auch durch irgendeine Antriebsvorrichtung, ζ. Β. ein Uhrwerk, bewirkt werden. Zweckmäßig gestaltet man die Einrichtung so, daß sowohl die Zeitdauer einer Bewegung als auch die Hub-The up ■ and downward movement of the tube c can both by hand and by any drive device, ζ. Β. clockwork. Purposefully designed the device so that both the duration of a movement and the lifting
höhe des Röhrchens c veränderlich ist. Die Form des Röhrchens wird den verschiedenen zu messenden Flüssigkeiten jeweils angepaßt werden müssen.height of the tube c is variable. The shape of the tube will have to be adapted to the different liquids to be measured.
Die ganze Einrichtung läßt sich naturgemäß vielfach abändern, ohne jedoch den eigentlichen Gedanken der Erfindung auszuschalten.The whole facility can of course be modified many times, but without the actual one Turn off thoughts of the invention.
