Description

Blitzlichtpulver. Die Verwendung von Sulfaten als Treibmittel für Blitzlichtpulv er ist bekannt. Vor allem wurden die Sulfate des Magnesiums, der alkalischen und seltenen Erden verwendet. Die letztgenannten Sulfate zeichnen sich vor den übrigen durch eine ganz besondere Lichtwirkung aus.Flash powder. The use of sulfates as a propellant for Blitzlichtpulv he is known. Above all, the sulphates of magnesium, the alkaline and rare earths used. The latter sulfates stand out from the others through a very special lighting effect.

Wir haben nun gefunden, daß man dieselbe hohe Lichtintensität erzielen kann, wenn man an Stelle der schwer zu beschaffenden Sulfate der seltenen Erden das Magnesium mit dem leicht zugänglichen Bleisulfat mischt. Man erhält auf diese Weise Blitzlichtpulver von ganz besonderer photochemischer Wirksamkeit, die entgegen der Voraussicht bei sachgemäßer Anwendung keine toxischen Wirkungen zeigen.We have now found that the same high light intensity can be achieved can, if you replace the hard-to-find rare earth sulfates the magnesium mixes with the easily accessible lead sulfate. One receives on this Way flash light powder of very special photochemical effectiveness that opposes show no toxic effects if used properly.

Beispiel. r oo g Magnesium werden mit r oo g Bleisulfat innigst gemischt und das Gemisch mit Hilfe von Salpeterpapier oder ähnlichem Zündtnaterial zum Verpuffen gebracht.Example. r oo g magnesium are mixed intimately with r oo g lead sulphate and the mixture with the aid of saltpeter paper or similar ignition material to deflagrate brought.
