PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung besteht aus einem Verfahren und Apparat zur Bestimmung des Flüssigkeitsgrades von Mineralölen und anderen Flüssigkeiten bei den verschiedensten Temperaturen.The present invention consists of a method and apparatus for determining the The degree of fluidity of mineral oils and other fluids in the most varied Temperatures.
Während die schon bekannten, dem gleichen Zweck dienenden Apparate durch die Bestimmung der Ausflufsgeschwindigkeit das gesuchte Ergebnifs liefern, beruht das vorliegende neue Verfahren lediglich auf Messung der Zeitdauer, welche eine Luftblase bedarf, um in der zu prüfenden Flüssigkeit emporzusteigen.While the already known apparatus serving the same purpose through the determination deliver the result sought after the outflow velocity, the present new one is based The method is based solely on measuring the length of time that an air bubble needs to be in the to ascend the liquid to be tested.
Das Verfahren ist folgendes:The procedure is as follows:
Ein cylindrisch geformter Glasbehälter, welcher durch einen sorgfältigst .eingeschliffenen Glaspfropfen geschlossen werden kann, wird mit der zu prüfenden Flüssigkeit so weit gefüllt , dafs nach Einführung .des Pfropfens' unter demselben bis zur Flüssigkeitsfläche ein genau bemessener, mit Luft gefüllter Leerraum verbleibt. Der Glascylinder wird hierauf gestürzt, so dafs das ' obere, mit dem Glaspfropfen versehene Ende senkrecht nach unten steht und sodann mit Hülfe der Secundenuhr die Zeitdauer bestimmt, welche die in der Flüssigkeit aufsteigende Luftblase bedarf, um von unten nach oben zu kommen.A cylindrically shaped glass container, which has been carefully ground in Glass stopper can be closed, is filled with the liquid to be tested so far , that after the introduction of the "plug" it flows under it as far as the surface of the liquid precisely measured empty space filled with air remains. The glass cylinder will then overturned, so that the 'upper end, provided with the glass stopper, vertically downwards stands and then, with the help of the second clock, determines the duration of the time in the A rising air bubble requires liquid to come up from below.
Zur praktischen und sicheren Anwendung dieses Verfahrens'dient der in der beiliegenden Zeichnung dargestellte Apparat.For the practical and safe application of this procedure, the enclosed Apparatus shown in the drawing.
Fig. i. zeigt den Apparat von vorn, Fig: 2 von oben gesehen; Fig. 3 ist ein Schnitt nach A-B in Fig. 2.Fig. I. shows the apparatus from the front, FIG. 2 seen from above; FIG. 3 is a section along AB in FIG. 2.
Der Glasbehälter besteht hier aus einer Röhre a, welche an ihren Enden mit je einem Glaspfropfen α : geschlossen und mit den Markirungen a1 versehen ist. Der Behälter a ist in die mit Oeffhung versehene Welle b straff eingesetzt und mit dieser vermittelst der Zapfen c an dem Gestell d drehbar gelagert, und zwar derart, dafs bei Drehung der an den Zapfen festsitzenden Scheiben c1 sich Welle und Glasbehälter mit den Zapfen drehen. Die Drehung ist durch die an der Welle sitzenden Lappen e und durch die am Gestell angebrachten Theile g begrenzt, so dafs der Glasbehälter , nachdem derselbe bis zur oberen Markirung a'2 mit der zu prüfenden Flüssigkeit gefüllt und sodann durch den Glaspfropfen wieder geschlossen ist, rasch und sicher gestürzt, und senkrecht gestellt werden kann. Fig. 1 ' zeigt den gefüllten und gestürzten Glasbehälter mit der aufsteigenden Luftblase h. The glass container here consists of a tube a, which is closed at each end with a glass plug α : and is provided with the markings a 1 . The container a is tightly inserted into the shaft b provided with an opening and with this the pin c is rotatably mounted on the frame d, in such a way that when the disks c 1 are rotated, the shaft and the glass container rotate with the pin . The rotation is determined by the seated on the shaft flaps e and by the mounted on the frame part g limited; so that the glass container after it is closed up to the upper Markirung a '2 is filled with the liquid to be tested then through the glass plug again, can be overturned quickly and safely and placed vertically. Fig. 1 'shows the filled and overturned glass container with the rising air bubble h.
Das Gestell d ist zur Bestimmung und Regulirung seiner senkrechten Stellung mit einer Senkwaage k, sowie drei Stellschrauben m und zur Bestimmung der Temperatur mit einem Thermometer η versehen.To determine and regulate its vertical position, the frame d is provided with a lowering balance k, as well as three adjusting screws m and for determining the temperature with a thermometer η .
Verfahren und Apparat sind so einfach, dafs in rascher Folge eine beliebige Zahl von Messungen vorgenommen werden kann.The method and apparatus are so simple that any number of Measurements can be made.
