Description

Vorrichtung zur Beleuchtung von Wasserstandsgläsern. Es sind Wasserstandsanzeiger bekannt, bei welchen hinter dein Wasserstandsglas eine nur dieses erleuchtende Lichtquelle angeordnet ist. Die Lichtquelle ist dabei in einem Gehäuse so eingeschlossen, daß das Wasserstandsglas in voller Breite beleuchtetist. Nach der Erfindung wird auf der Rückseite des Wasserstandsglases ein schmaler leuchtender Streifen erzeugt, dessen Breite nur einem Bruchteil des Durchmessers der Wassersäule entspricht. Zu dem Zweck wird, zwischen der hinter Min Wasserstandsglas angeordneten Lichtquelle und dem Wasserstandsglas eine Blende mit lichtdurchlässigem Längsschlitz angeordnet.Device for illuminating water level glasses. They are water level indicators known, in which there is only this illuminating light source behind your water level glass is arranged. The light source is enclosed in a housing so that the full width of the water level glass is illuminated. According to the invention is on creates a narrow, glowing stripe on the back of the water level glass, whose width is only a fraction of the diameter of the water column. to the purpose is between the light source arranged behind the Min water level glass and a diaphragm with a translucent longitudinal slit is arranged on the water level glass.

Bei dieser Vorrichtung erscheint der Teil des leuchtenden Streifens, der sich hinter der Wassersäule befindet, breiter als der übrige Teil, und es entsteht ani oberen Ende der Wassersäule, also dort, wo der breite Streifen in den schmalen übergeht, infolgeder Wirkung der Wasserkuppe ein weithin sichtbarer hellleuchtender Punkt. Dieser erleichtert die Feststellung des Wasserstandes aus großer Entfernung ungemein. Es ist an sich wohlbekannt, die vergrößernde Wirkung der wassergefüllten Glasröhre bei Wasserstandsgläsern auszunutzen. Dabei hat man aber an der Rückseite des Glase:s schmale farbige Streifen angebracht, die selbst nicht leuchten und den auffallenden, helleuchtenden Punkt an der oberen Begrenzung der Wassersäule nicht entstehen lassen.With this device, the part of the luminous strip appears which is behind the water column, wider than the rest of the part, and it arises ani the upper end of the water column, i.e. where the broad stripe meets the narrow passes over, as a result of the effect of the Wasserkuppe, a brightly shining one that is visible from afar Period. This makes it easier to determine the water level from a great distance immensely. It is well known per se, the magnifying effect of the water-filled To take advantage of the glass tube for water level glasses. But you have it on the back of the glass: s narrow colored stripes attached, which do not light up themselves and the noticeable, brightly shining point at the upper limit of the water column let arise.

In der Zeichnung ist eine Ausführungsform der Vorrichtung dargestellt. Es zeigen: Abb. i eine Seitenansicht, Abb. 2 eine Vorderansicht.In the drawing, an embodiment of the device is shown. They show: FIG. 1 a side view, FIG. 2 a front view.

Hinter dem Rohr a des Wasserstandsanzeigers ist ein Kasten b angeordnet, welcher die Glühlampe c enthält. Die dem Rohr zugewandte Wand d dieses Kastens enthält den zum Rohr a parallelen Schlitz e, welcher mittels einer Glasscheibe verschlossen sein kann. Dieser schmale Schlitz erscheint, durch Wassersäule f betrachtet, als breiter leuchtender Streifen g, und es bildet sich am oberen Ende der Wassersäule infolg-e der Kuppe h im Schnittpunkt i ein weit sichtbarer hellleuchtender Punkt.Behind the tube a of the water level indicator, a box b is arranged, which contains the light bulb c. The wall d of this box facing the tube contains the slot e which is parallel to the tube a and which can be closed by means of a glass pane. When viewed through the water column f , this narrow slit appears as a broad luminous strip g, and a brightly luminous point that is visible from afar forms at the upper end of the water column as a result of the dome h at the point of intersection i.
