 EMI1.1 
 



   Es sind bereits Diapositive für Reklameprojektion bekannt, bei denen einem zwischen zwei Glasplatten eingeschlossenen Bilde durch   vorüberrieselnde   Glasperlen, Sand, Flüssigkeiten od. dgl. ein Bewegungseindruck verliehen wird. Bei der Verwendung von Flüssigkeiten hat es sich jedoch herausgestellt, dass bei öfteren Gebrauche die zur   Verdeckung   einzelner Bildteile bzw. zur Hervorrufung eines Farben-oder Bewegungseindruekes herangezogene Flüssigkeit, in Form von Tröpfchen am Diapositive haften bleibt, worunter die Projektion leidet.

   Dieser Nachteil wird erfindungsgemäss dadurch behoben, dass der Flüssigkeit chemische Mittel zugesetzt werden, die die Spannung zwischen Diapositiv und Glasplatten einerseits und dem abdeckenden flüssigen Mittel anderseits herabsetzen, wodurch   Insel- und Tröpfchenbildung   hintangehalten wird. Ein derartiger Zusatz ist z. B.   Türkischrotöl.   



   Da jedoch Glasperlen, Sand, Flüssigkeiten od. dgl. die Schichte des Diapositivs mehr oder weniger stark angreifen und das Bild in verhältnismässig kurzer Zeit beschädigen, wird erfindungsgemäss auf dem Diapositiv eine Schutzschicht angebracht, wozu sich besonders Nitrolacke eignen.

 EMI1.1
 



   There are already known slides for advertising projections in which an image enclosed between two glass plates is given an impression of movement by glass beads, sand, liquids or the like trickling past. When using liquids, however, it has been found that, with frequent use, the liquid used to cover individual parts of the image or to produce an impression of color or movement remains adhered to the slide in the form of droplets, which affects the projection.

   This disadvantage is eliminated according to the invention in that chemical agents are added to the liquid which reduce the tension between the slide and the glass plate on the one hand and the covering liquid agent on the other hand, thereby preventing island and droplet formation. Such an addition is e.g. B. Turkish red oil.



   However, since glass beads, sand, liquids or the like attack the layer of the slide to a greater or lesser extent and damage the image in a relatively short time, a protective layer is applied to the slide according to the invention, for which nitro lacquers are particularly suitable.

PATENT-ANSPRUCH : Diapositiv für Reklamezwecke, bei welchem dem zwischen zwei Glasplatten eingeschlossenen Bilde durch vorüberrieselnde Glasperlen, Sand, Flüssigkeiten od. dgl. ein Bewegungseindruck verliehen wird, dadurch gekennzeichnet, dass bei Verwendung von Flüssigkeiten diesen ein die Oberflächenspannung herabsetzendes Mittel, wie z. B. Türkischrotöl, beigesetzt wird und dass zum Schutze gegen Beschädigung des Diapositivs durch das vorüberrieselnde Material das Diapositiv einen Schutzanstrich mit Nitrolack erhält. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: A slide for advertising purposes, in which the image enclosed between two glass plates is given an impression of movement by glass beads, sand, liquids or the like trickling past over them, characterized in that when liquids are used these a surface tension-reducing agent, such as. B. Turkish red oil, is buried and that to protect against damage to the slide by the material trickling past the slide is given a protective coating with nitro lacquer. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
