Bei den bekannten Flüssigkeitsstandgläsern, bei denen in den Schaugläsern auf der Rückseite prismatische Rillen eingeschliffen sind, oder bei denen die Rückseite des Schauglases eben ist, besteht der Übelstand, daß man den Flüssigkeitsstand nicht gleich gut von vorn als auch von den Seiten richtig und deutlich sehen kann, da unter gewissem Winkel· die prismatischen Rillen die Strahlen in das WasserWith the well-known liquid level glasses, with those in the sight glasses on the back prismatic grooves are ground in, or where the back of the sight glass is even, there is the disadvantage that the fluid level cannot be checked immediately from the front as well as from the sides can see correctly and clearly, since at a certain angle · the prismatic grooves the rays in the water
ίο werfen und hell aufleuchten, so daß dies zu falschen Schlüssen Veranlassung gibt.ίο throw and light up brightly so that this too gives rise to wrong conclusions.
Diese Erfindung betrifft nun ein Schauglas für Flüssigkeitsstandanzeiger, das sich dadurch kennzeichnet, daß man den dahinter befmdliehen Flüssigkeitsstand sowohl von vorn als auch von den Seiten gut sehen kann.This invention now relates to a sight glass for liquid level indicators which is thereby indicates that the liquid level behind it can be viewed both from the front and from the can also see well from the sides.
Gemäß der Erfindung wird die Rückseite des Schauglases nicht allein mit den bekannten prismatischen Rillen, sondern auch mit ebenen Streifen versehen, und zwar derart, daß die prismatischen Rillen abwechselnd von ebenen Streifen unterbrochen sind oder von diesen begrenzt werden.According to the invention, the back of the sight glass is not alone with the known prismatic grooves, but also provided with flat strips, in such a way that the prismatic grooves are alternately interrupted by flat strips or by these be limited.
Wenn man nun das Schauglas von vorn ansieht, so leuchten die prismatischen Rillen hell auf, und die Flüssigkeit ist schwarz. Ebenso treten die Streifen so gut wie gar nicht hervor. Von der Seite gesehen leuchten aber die Streifen auf und die prismatischen Rillen nicht, so daß die Flüssigkeit auf den Streifen schwarz erscheint.If you now look at the sight glass from the front, the prismatic grooves shine brightly and the liquid is black. Likewise, the stripes hardly appear at all. Seen from the side, however, the stripes light up and the prismatic grooves do not, so that the liquid appears black on the strip.
Auf der Zeichnung ist der Erfindungsgegenstand in Fig. ι in der Ansicht und in Fig. 2 und 3 im Querschnitt in zwei Ausführungsformen veranschaulicht. In the drawing, the subject of the invention is shown in FIG. 1 in the view and in FIG. 2 and Fig. 3 illustrates in cross section in two embodiments.
α ist das Wasserstandsglas, b sind die Rillen und c die Streifen. α is the water level glass, b are the grooves and c the stripes.
Die Schaufläche des Glases kann in bekannter Weise prismatisch gestaltet sein.The viewing surface of the glass can have a prismatic design in a known manner.
Die Anordnung der prismatischen Rillen und Streifen kann in verschiedener Ausführung erfolgen. Es können z. B. auf der Rückseite des Schauglases mehrere prismatische Rillen nebeneinander angeordnet sein, die von Streifen begrenzt werden, oder es können auch mehrere prismatische Rillen in Gruppen angeordnet sein, zwischen welchen ein Streifen liegt.The arrangement of the prismatic grooves and strips can be in various designs take place. It can e.g. B. several prismatic grooves on the back of the sight glass be arranged side by side, which are limited by strips, or it can also several prismatic grooves can be arranged in groups, between which a strip lies.
