JV£ 128310 -KLASSE 806.JV £ 128310 - CLASS 806.
Patentirt im Deutschen Reiche vom 26. Mai 1901 ab. Längste Dauer: 21. Juni 1914.Patented in the German Empire on May 26, 1901. Longest duration: June 21, 1914.
In der Patentschrift 120281 ist ein Verfahren beschrieben, welches darin besteht, dafs gepulverte granulirte Hochofenschlacke mit Kalkwasser oder mit Wasser ohne Kalkgehalt angefeuchtet, in dicht verschlossene, d. h. verschliefsbare, Formen gefüllt und in denselben der Wirkung von Heifswasser oder Wasserdampf ausgesetzt wird. Die Schlacke sucht unter der Wirkung des erhitzten Kalkwassers oder Wassers ihr Volumen zu vermehren; durch die sie umschliefsende feste Form hieran aber gehindert, verdichtet sie sich in sich selbst und erhärtet zu einem steinartigen Pro- ; duct.In the patent specification 120281 a method is described which consists in dafs powdered granulated blast furnace slag with lime water or with water without lime content moistened, in tightly closed, d. H. closable, forms filled and in the same exposed to the action of hot water or steam. The slag is looking to increase their volume under the action of the heated lime water or water; but prevented from doing so by the solid form surrounding it, it condenses in itself itself and hardens to a stone-like pro-; duct.
Die erste Bedingung zur Hervorrufung der gekennzeichneten Wirkung ist die, dafs die Feuchtigkeit, mit der die in die geschlossenen Formen eingefüllte gepulverte Schlacke innigst durchsetzt ist, auf höhere Temperatur gebracht wird. "^The first condition for producing the marked effect is that the Moisture with which the powdered slag poured into the closed molds intimately is permeated, is brought to a higher temperature. "^
Nach dem Haupt-Patente wird dies also dadurch erreicht, dafs Heifswasser oder Wasserdampf auf die in den geschlossenen Formen befindliche angefeuchtete Schlacke zur Einwirkung gebracht wird. Hierzu kann z.B. der Abdampf der Dampfmaschine verwendet werden, den man geeigneterweise vor seiner Anwendung überhitzt.According to the main patent, this is achieved by using hot water or steam on the moistened slag in the closed molds to act is brought. For this purpose, e.g. the exhaust steam of the steam engine can be used, which is suitably placed in front of his Application overheated.
Diese Anwendung von Heifswasser oder Wasserdampf von beliebiger Spannung und Temperatur hat aber den Nachtheil, dafs sie auf die Metallformen ungünstig einwirkt, indem sie z. B. eiserne Formen leicht zum Rosten bringt.This application of hot water or steam of any voltage and But temperature has the disadvantage that it has an unfavorable effect on the metal forms by she z. B. easily rusts iron forms.
Um diesen Uebelstand zu vermeiden, ist es zweckmäfsig, nicht Wasser oder Wasserdampf, sondern eine trockene Wärme, wie heifse Feuergase, heifse Luft oder dergl., auf die in den geschlossenen Formen befindliche angefeuchtete gepulverte Schlacke einwirken zu lassen, zum Zwecke, den gekennzeichneten Versteinerungsprocefs ohne Schädigung der Formen herbeizuführen.In order to avoid this inconvenience, it is advisable not to use water or steam, but a dry heat, like hot fire gases, hot air or the like, on the Moistened powdered slag in the closed molds act to it let, for the purpose, the marked petrification process without damaging the To bring about forms.
