Description

Auergesellschaft Aktiengesellschaft Röhrchen zur Aufspürung von Gasen. --------------------------------- Die zum Zwecke der Aufspürung von Gasen verwendeten Röhrchen bestehen ans Glas oder durchsichtigen Kunststoffen.Auergesellschaft Aktiengesellschaft Tubes for the detection of gases. --------------------------------- The tubes used to detect gases are made of glass or transparent plastics.

In ihnen sind auf Sieben oder Glaswollpfropfen die Chemikalien gelagert, welche mit den nachzuweisenden Gasen reagieren und dabei eine vom ursprünglichen Zustand abweichende Färbung annehmen. Bei manchen Röhrchen ist aber die Reaktionsmasse mit der Anzeigemasse nicht identisch, sondern die in der Reaktionmasse auftretende chemische Reaktion ergibt eine Umwandlung des nachzuweisenden Gases, und die entstehenden Umwandlungsprodukte werden in einer hinter der Reaktionsschicht gelagerten Anzeigeschicht durch deren Umfärbumg erkennbar gemacht. Für den die Spurtätigkeit Ausübenden ist es daher wichtig, zu wis- sen, welchem Ende des Röhrchens die zu prüfende Luft zugeführt werden muss bezw. welches Rohrchenende an die zur Förderung der Luft dienende Pumpe angeschlossen wird. Bei falscher Strö- mungsrichtung wäre ja die Spürtätigkeit illusorisch. Ausserdem können auch bei falscher Strömungsrichtung Stoffe aus der Röhrchenfüllung in die Ansaugepumpe gelangen, die von einer besonderen Abfang- oder Anzeigeschicht zurückgehalten werden sollten.In them, the chemicals are stored on sieves or glass wool plugs, which react with the gases to be detected and thereby take on a color deviating from the original state. In some tubes, however, the reaction mass is not identical to the display mass, but the chemical reaction occurring in the reaction mass results in a conversion of the gas to be detected, and the conversion products are made recognizable in a display layer behind the reaction layer by their color change. For It is therefore important for those who do the tracking to know sen which end of the tube the air to be tested is supplied to must be or. which tube end to which to promote the air serving pump is connected. In the event of a wrong fault The sense of direction would be illusory. In addition, even if the flow direction is wrong, substances from the tube filling can get into the suction pump, which should be held back by a special interceptor or indicator layer.

Durch die Neuerung wird der beschriebene Mangel vermieden. Die Neuerung besteht darin, dass das Röhrchen am Lufteintrittsende mit einer Verdickung versehen ist, welche verhindert, dass es mit diesem Ende an die Pumpe angeschlossen werden kann, die nur eine Öffnung vom Querschnitt des Röhrchens besitzt. Dadurch wird die Verwendung des Röhrchens im verkehrten Sinne vermieden. Die Verdickung ist vorzugsweise als nach außen springender Wulst entwickelt, der unmittelbar hinter der zur Spitze ausgebildeten Abschmelzstelle des Röhrchens liegt. The defect described is avoided by the innovation. The innovation is that the tube is provided with a thickening at the air inlet end which prevents it from being connected to the pump with this end can, which has only one opening of the cross section of the tube. This will make the Avoid using the tube in the wrong way. The thickening is preferable developed as an outwardly jumping bulge, the one immediately behind that to the point formed melting point of the tube lies.

Die Zeichnung stellt ein Ausführungsbeispiel der Neuerung dar. Darin ist 1 das aus Glas oder Kunststoff bestehende Röhrchen, welches beispielsweise eine Reaktionsschicht 2 und eine Anzeigeschicht 3 enthalt. Beide Schichten sind von einer kurzen, luftdurchlässigen Trennachieht 4 geschieden. Die Schichten sind an ihren Enden von Slaswollpfropfen 6 begrenzte Die Röhrchenwand ist an beiden Enden zu Spitzen ausgezogen, die zum Öffnen des Röhrchens vor der Spürtätigkeit abgebrochen werden müssen. Unmittelbar hinter der am Eintrittsende befindlichen Spitze 7 ist eine wulstförmige Verdickung 9 angeordnet. The drawing represents an exemplary embodiment of the innovation 1 is the tube made of glass or plastic, which, for example, is a Reaction layer 2 and a display layer 3 contains. Both layers are of one short, air-permeable separator 4 divorced. The layers are on theirs Ends of slaswool plugs 6 limited The tube wall is on both Ends pulled out to tips that open the tube before sensing must be canceled. Immediately behind the one at the entrance end At the tip 7, a bead-shaped thickening 9 is arranged.
