Description

Zündschnur. Der Erfindung gemäß wird eine Zündschnur aus der Mischung einer pulverförmigen Zündmasse mit Gummi oder einer Gummimischung erzeugt. Gegenüber bekannten Versuchen, eine Zündschnur aus einer plastischen, Masse herzustellen, ergibt die 'Verwendung einer Bindemasse aus 'Gummi oder einer Gummimischung gewisse Vorteile, die erst die allseitige Verwendung einer derartigen Zündschnur ermöglichen. Keine Biegungen oder sonstige an Zündschnüre herantretende Beanspruchungen können eine Unterbrechung der Leitungsfähigkeit herbeiführen. Insbesondere hat die Bindemasse aus Gummi die Wirkung, daß die Zündschnur selbst unter Wasser die Zündung gleichmäßig und zuverlässig weiterleitet. Der Gummi hat auch die Eigenschaft, die pulverförmige Zündmasse in der feinsten Verteilung festzuhalten, so daß eine Schnur entsteht, die durchaus homogon und gummiartig erscheint, obwohl die feinen Partikelchen der Zündmasse einen wesentlichen Bestandteil der Gesamtmasse bilden. Letzterer Umstand stört aber nicht die Fortleitung der Zündung, da der Gummi in einem solchen Grazie brennbar ist, daß er die Fortleitung der Zündung nicht unterbricht und sogar etwa vorhandene ganz kleine Zwischenräume überbrückt. Der Gummi ist ein unbedingt zuverlässiges Mittel gegen das Eindringen von Feuchtigkeit zu den Partikelchen der Zündmasse, weshalb die Zündschnur, wie gesagt, auch zur Verwendung unter Wasser besonders geeignet ist. Die Geschmeidigkeit der Zündschnur ist praktisch dieselbe wie diejenige -einer Gummischnur.Fuse. According to the invention, a fuse is made from the mixture a powdery ignition compound with rubber or a rubber mixture. Opposite to known attempts to produce a fuse from a plastic, mass, the 'use of a binding compound made of' rubber or a rubber mixture gives certain results Advantages that only make it possible to use such a fuse on all sides. There can be no bends or other stresses on fuses cause an interruption of the conductivity. In particular, the binder has Made of rubber the effect that the fuse even underwater ignites evenly and forwards it reliably. The rubber also has the property of being powdery To hold the ignition material in the finest distribution, so that a cord is formed, which appears quite homogeneous and rubbery, although the fine particles of the Ignition mass form an essential part of the total mass. The latter circumstance but does not interfere with the propagation of the ignition, as the rubber works in such a grace is flammable that it does not interrupt the continuation of the ignition and even about bridges existing very small gaps. The rubber is absolutely reliable Means against the penetration of moisture to the particles of the ignition material, which is why the fuse, as I said, is particularly suitable for use under water is. The suppleness of the fuse is practically the same as that of one Elastic cord.

Bei der Herstellung der Zündschnur wird die aus einer innigen Mischung der pulverförmigen Zündmasse mit einer flüssigen Gummimischung bestehende Masse in Fäden, oder besser in Schläuche, ausgezogen oder gepreßt, in welch letztere zur Verstärkung ein Faden eingeschlossen sein kann, was aber nicht unerläßlich ist. Selbstverständlich kann die Zündschnur auch noch durch eine äußere Textilhülle o. dgl. oder einen sonstigen Schutz umgeben werden; aber auch dies ist durchweg nicht erforderlich. -The manufacture of the fuse is made from an intimate mixture the powdery ignition mass with a liquid rubber mixture existing mass in threads, or better in tubes, drawn out or pressed, in which the latter for Reinforcement a thread can be included, but this is not essential. Of course, the fuse can also be covered by an outer textile cover or the like. like. Or some other protection are surrounded; but this is not always the case either necessary. -
