KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Wenn man eine innige Mischung von Kieselgur, Ton ο. dgl. mit einem geeigneten Flußmittel, ζ. Β. Salz, Flußspat, bei hoher Temperatur brennt, so entsteht eine gesinterte poröse Masse, die ein ganz hervorragendes Filtermaterial darstellt, das sich durch Festigkeit und hohe Filtriergeschwindigkeit auszeichnet. Allerdings vermag es Bakterien aus verseuchtem Wasser nur zum Teil zurückzuhalten. Dies rührt daher, daß bei dem eben geschilderten Prozeß durch die Einwirkung des Bindemittels auf Kieselgur ein teilweises Schmelzen der letzteren und dadurch die Zerstörung ihrer Struktur hervorgerufen wird. Anerkanntermaßen beruht aber die Fähigkeit der Kieselgur, ein bakterienfestes Filtriermaterial zu liefern, auf der außerordentlich feinen Struktur der Kieselsäureskelette mikroskopischer Radiolarien.If you have an intimate mixture of diatomite, clay ο. the like with a suitable flux, ζ. Β. Salt, fluorspar, burns at a high temperature, creating a sintered one porous mass, which is a very excellent filter material, which is characterized by strength and high filtration speed. However, bacteria can do it withhold contaminated water only partially. This is due to the fact that in the case of the The process described is partially due to the action of the binding agent on diatomaceous earth Melting of the latter and thereby the destruction of their structure is caused. However, it is recognized that diatomaceous earth is able to act as a bacteria-proof filter material to deliver, microscopic on the extraordinarily fine structure of the silica skeleton Radiolarians.
Führt man jedoch den eben geschilderten Brennprozeß bei Temperaturen durch, die zu einem gründlichen Zusammenschmelzen der Filterbestandteile nicht ausreichen, so erhält man, da in diesem Falle die Kieselgur vollkommen als solche erhalten bleibt, ein bakterienfestes Filtermaterial, das, wie in derHowever, if you follow the one just described Firing process at temperatures that lead to a thorough melting of the If the filter components are not sufficient, in this case the kieselguhr is obtained as such, a bacteria-proof filter material is retained, which, as in the
* *> Natur der Sache liegt, sehr spröde und äußerst empfindlich gegen mechanische oder physikalische Eingriffe ist.* *> The nature of the matter is very brittle and extremely is sensitive to mechanical or physical interference.
Die neue Erfindung nun beruht darauf, daß man einen Filterkörper bei hoher Temperatur erbrennt, auf ihn weitere Filtermasse aufträgt oder in ihn hineinträgt und bei niederer Temperatur nachbrennt. Man erhält so Platten, Kerzen usw., bestehend aus LagenThe new invention is based on the fact that you have a filter body at high temperature burns, applies further filter material to him or carries it into him and with lower Temperature continues to burn. This gives plates, candles, etc., consisting of layers

Zu -dem· gleichen Ziele gelangt man, wenn man durch Veränderung der Mischungsverhältnisse und zweckentsprechende Auswahl des Flußmittels die Sinterungsgrenzen der Rohmischungen für die verschiedenen Filterschichten so auseinanderrückt, daß beim Erhitzen auf eine bestimmte Temperatur die eine Mischung unter Zerstörung der Struktur der Kieselgur zu einer harten klinkerartigen Masse zusammensintert, während die andere eben die Sintergrenze erreicht.hard and soft filter material with high strength and filtration speed Absolutely impermeable to germs of all kinds. -Achieved the same goals one, if one by changing the mixing ratios and appropriate Selection of the flux the sintering limits of the raw mixes for the various filter layers so apart that when heated to a certain temperature, the one mixture destroys the structure the kieselguhr sinters into a hard clinker-like mass, while the other just reached the sinter limit.
