Description
Verfahren zum Zünden einer Reihe von Sprengschüssen. Das Hauptpatent (und die dazugehörigen Zusatzpatente 379872, 379939 und -1261i8) haben das Merkmal, daß an Stelle der vorher üblichen Zündschnüre in die Sprengkapseln oder Zünderhülsen Verzögerungsmittel eingepreßt werden. Die beim Zünden austretenden Gase lassen befürchten, daß umbeabsichtigte Explosionen. Schlagwetter u. dgl. auftreten können.Method of detonating a series of explosive shots. The main patent (and the associated additional patents 379872, 379939 and -1261i8) have the feature that delay agents are pressed into the detonator capsules or detonator sleeves instead of the previously usual fuses. The gases escaping during ignition give rise to the fear of unintentional explosions. Firedamp and the like can occur.
Diese Gefahr wird durch die Erfindung beseitigt, welche in der Anordnung einer Schutzhülse besteht, durch welche die Gase an die Einführungsstelle der Zünderdrähte geführt werden. Das hat zur Folge, da.ß Druck und Temperatur der Gase auf dem Wege vom Entgasungskanal bis zur Austrittsstelle so herabgesetzt werden, daß sie nicht mehr die Fähigkeit besitzen, Schwarzpulver, schwarzpulverähnliche Sprengstoffe oder Schlagwetter zur Zündung zu bringen.This danger is eliminated by the invention which is included in the arrangement consists of a protective sleeve through which the gases to the insertion point of the detonator wires be guided. The consequence of this is that the pressure and temperature of the gases on the way from the degassing channel to the exit point are reduced so that they are not more capable of gunpowder, black powder-like explosives or To ignite firedamp.
In der Zeichnung sind zwei beispielsweise Ausführungsformen der Erfindung in Aufriß und Querschnitt dargestellt. Die mit der Verzögerung versehene Sprengkapsel a wird,- wie üblich, von der Zünderhülse b umgeben und weist einen besonderen Entgasungskanal c (Abb. r) auf. In Abb. 2 sind Austrittsöffnungen c in der Zünderhülse für die Gase vorgesehen. Um die Zünderhülse ist die Schutzhülse d gezogen, welche zwangläufig die Gase an die Einführungsstelle der Zünderdrähte führt, wo diese in der Richtung der einge zeichneten Pfeile entweichen.In the drawing are two exemplary embodiments of the invention Shown in elevation and cross-section. The detonator with the delay a is - as usual, surrounded by the detonator sleeve b and has a special degassing channel c (fig.r). In Fig. 2 there are outlet openings c in the igniter sleeve for the gases intended. The protective sleeve d is drawn around the detonator sleeve, which inevitably the gases to the insertion point of the detonator wires, where they lead in the direction the drawn arrows escape.
