   50 9 Knochenkohle, 15 9 feinssockiges Asbest   und 10 g Zellulose werden nun in einem reichlichen Liter Wasser aufgeschwemmt und die Mischung wird möglichst gleichmässig auf die eben ausgebreitete   Stofffläche     aufgegssen. Sollte sleh beim Abfliessen   des Wassers eine gelbliche Färbung zeigen, so ist ein mehrmaliges   Nachgiessen   von kaltem Wasser zum Auslaugen des betreffenden Farbstoffes erforderlich.

   (Schon hiebei zeigt es sich, dass der vorgekochte Stoff keine Knochenkohle mehr durchlässt.) Ist das Wasser zuletzt klar abgeflossen, so stellt man das Sieb mit dem Stoff an einen warmen Ort zum schnellen Austrocknen und legt ihn dann kurz vor der gänzlichen Trockenheit unter eine Presse, entweder wieder zwischen Glanzpapiere oder zwischen zwei blanke Metallplatten und lässt ihn mehrere Stunden in der Presse stehen. Hierauf wird der Stoff herausgenommen und nochmals mittels kalter, schwerer Walze ausgewalzt. 



   Durch dieses Verfahren wird ein absolut sicheres Binden einer   reichlichen   Menge von Kohle in dem Faserstoff und eine innig feine Verfilzung des Asbests mit den Fasern des Filterstoffes erreicht.

   50 9 bone charcoal, 15 9 fine-socked asbestos and 10 g cellulose are now suspended in a large liter of water and the mixture is poured as evenly as possible onto the fabric surface that has just been spread out. If it should show a yellowish color as the water drains off, it is necessary to pour cold water several times to leach out the dye in question.

   (This already shows that the pre-cooked material no longer lets bone charcoal through.) If the water has finally drained off clearly, the sieve with the material is placed in a warm place to dry out quickly and then placed under a shortly before it is completely dry Press, either again between glossy paper or between two bare metal plates and let it stand in the press for several hours. The fabric is then removed and rolled out again using a cold, heavy roller.



   This process ensures that a large amount of carbon is bound in the fiber material in an absolutely secure manner and that the asbestos is entangled with the fibers of the filter material.

Verfahren zur Herstellung eines Filterstoffes unter Anwendung von Kohlenpulver oder gleichwertigen Filtriermaterialien, dadurch gekennzeichnet, dass auf einem gut durchlässigen, feinfaserigen Stoff in einem heissen Wasserbade Knochenhohh'oder dgl. nieder- geschlagen wird und ein zweiter Niederschlag aus faserigen Filtermaterialien, eventuell mit Knochenkohle oder dgl. gemischt, auf nassem Wege derart aufgebracht wird, dass die Fasern des zweiten Niederschlages durch das Kohlenpulver hindurch mit den Fasern des unteren Filterstoffes derart verfilzen, dass die einzelnen feinen Teilchen des Kohlenpulvers zwischen den verfilzten Fasern des Faserstoffes eingebettet liegen. Process for the production of a filter material using carbon powder or equivalent filter materials, characterized in that bones or the like are precipitated on a well-permeable, fine-fiber material in a hot water bath, and a second deposit of fibrous filter materials, possibly with bone charcoal or the like mixed, is applied by wet means in such a way that the fibers of the second deposit are felted through the carbon powder with the fibers of the lower filter material in such a way that the individual fine particles of the carbon powder are embedded between the felted fibers of the fiber material.
