KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Durch die amerikanische Patentschrift 248413 ist bereits ein Verfahren bekannt geworden, nach welchem Kalziumsulfid in inniger Vermischung mit zerkleinertem Gummikampfer einer Zelluloidmasse zur Gewinnung einer Leuchtmasse zugesetzt werden soll.A process has already become known through the American patent specification 248413, after which calcium sulfide in intimate mixing with crushed rubber camphor to be added to a celluloid mass to obtain a luminous mass.
Gewerblich konnte sich dieses Verfahren nicht bewähren und sind auch danach hergestellte Leuchtmassen nicht in den Verkehr gebracht worden.This process could not prove itself commercially and are also manufactured according to it Luminous masses have not been placed on the market.
Das Zelluloid entbindet infolge seiner sauren Reaktion aus dem Kalziumsulfid Schwefelwasserstoffgas, das Geruchbelästigung und unangenehme chemische Umsetzungen verursacht, die die Masse sich braun oder grünlich verfärben lassen und wobei das Kalziumsulfid seine Leuchtkraft vollständig verliert und zerstört wird.As a result of its acidic reaction, the celluloid releases hydrogen sulfide gas from the calcium sulfide, which causes odor nuisance and unpleasant chemical reactions that discolour the mass brown or greenish let and wherein the calcium sulfide completely loses its luminosity and destroys it will.
Die gleichen Erscheinungen treten ein, wenn ein Kalziumsulfid-Zelluloidgemisch der Wärme ausgesetzt wird, was zum Formen der Masse unbedingt erforderlich ist.The same phenomena occur when a calcium sulfide-celluloid mixture is exposed to heat is exposed to what is absolutely necessary to shape the mass.
Das vorliegende Verfahren betrifft dagegen eine leuchtende formbare Masse, die aus leuchtendem Zinksulfid bzw. dem daraus hergestellten radioaktiven Zinksulfid und dem sich vollständig neutral verhaltenden Zellon, Galalith, Gelatine o. dgl. besteht. Die Verbindung des Zinksulfids mit der Zellon- o. dgl. Masse wird durch Kneten, Walken 0. dgl. so hergestellt, daß möglichst keine Kristalle gerieben und zerstört werden, da sonst die Leuchtkraft wesentlich leidet. Die so hergestellte Leuchtmasse ist vollständig klar und dauerhaft, ihre Lichtstrahlen kommen im Gegensatz zu den mit Kalziumsulfid hergestellten Massen voll und klar ohne einen nebligen Schleier zur Geltung und besitzen eine wesentlich erhöhte Leuchtkraft. Ein weiterer wesentlicher Vorzug der radioaktiven Zinksulfidmasse ist, daß sie keiner vorherigen Belichtung durch Tageslicht oder einer künstlichen Lichtquelle bedarf, sondern mit bedeutender Energie Licht aus sich selbst entwickelt.The present method, however, relates to a luminous, malleable mass that consists of luminous Zinc sulphide or the radioactive zinc sulphide produced from it and the itself Completely neutrally behaving Zellon, Galalith, gelatine o. The like. Consists. The connection the zinc sulphide with the Zellon or the like mass is produced by kneading, milling, etc. in such a way that that if possible no crystals are rubbed and destroyed, otherwise the luminosity suffers significantly. The luminous material produced in this way is completely clear and permanent, theirs In contrast to the masses made with calcium sulfide, light rays come full and clear without a misty veil and possess a much increased Luminosity. Another major benefit of the radioactive zinc sulfide mass is that it does not require prior exposure to daylight or an artificial light source, but develops light from itself with significant energy.
Nach der bisherigen Forschung auf dem 4^ Gebiete der Radioaktivität besteht diese Lichtwirkung in dem Ausschleudern kleiner Heliumatome gegen einen Phosphoreszensschirm, der hierdurch zur Lichtemission erregt wird.According to previous research in the 4 ^ areas of radioactivity, these light effect consists in ejecting small helium atoms against a Phosphoreszensschirm which is thereby excited to emit light.
Diese Leuchtwirkung läßt sich berechnen und durch Wahl geeigneter Präparate verändern, so daß man von zeitlich begrenzter und auch fast unbegrenzter Dauer der Massen sprechen kann.This luminous effect can be calculated and changed by choosing suitable preparations, so that one can speak of a temporally limited and also almost unlimited duration of the masses.
Durch das Einbetten des Zinksulfids in die Zellon- o. dgl. Masse wird der Luftzutritt verhindert und die Lebensdauer des Leuchtstoffs wesentlich verlängert.By embedding the zinc sulphide in the cellulose or similar mass, the entry of air is prevented and significantly extends the life of the phosphor.
Die so hergestellte Leuchtmasse kann beliebig geformt und verarbeitet werden, sie läßt sich in Platten schneiden, in Röhren und Stangen ziehen, man kann Tiefprägungen daraus herstellen und Hohlkörper für die Spielwarenindustrie blasen usw. mehr.The luminous material produced in this way can be shaped and processed in any way, it can Cut yourself into plates, pull yourself into tubes and rods, you can make deep embossing out of them manufacture and blow hollow bodies for the toy industry, etc. more.
