Description

Verfahren zum Zünden einer Reihe von Sprengschüssen mittels elektrischer Zeitzünder. Im Hauptpatent ist ein Verfahren zum Zünden einer Reihe von Sprengschüssen mittels elektrischer Zünder beschrieben, welches darin besteht, daß in die Sprengkapseln Verzögerungstabletten oder Verzögerungssätze eingepreßt werden, welche die Funktion der Zündschnüre übernehmen sollen.Method of igniting a series of explosive shots by means of electrical Time fuse. In the main patent is a method for igniting a series of explosive shots described by means of electric detonator, which consists in that in the detonators Delay tablets or delay sentences are pressed in, which the function the fuses should take over.

Weitere Versuche haben nun ergeben, daß man auch zweckmäßig Verzögerungsstücke anwenden kann, deren Außenmantel aus Aluminium, Kupfer, Messing, Eisen oder sonstigen hierzu geeigneten Metallen oder aus Celluloid, Kunststoffen, Pappmache usw. und deren Kern aus Verzögerungssätzen oder -pulver bestehen. Diese Verzögerungsstücke werden in der bekannten Weise in die Sprengkapseln eingesetzt bzw. eingepreßt.Further experiments have now shown that it is also expedient to use delay pieces can use whose outer sheath made of aluminum, copper, brass, iron or other suitable metals or celluloid, plastics, paper mache, etc. and whose core consists of delay sentences or powder. These delay pieces are inserted or pressed into the detonators in the known manner.

Der Raum zur Aufnahme der Tabletten und Pulversätze in den Sprengkapselhülsen ist nach dem Hauptpatent der normale Leerraum, den jede Sprengkapsel zur Aufnahme der Zündschnur haben muß. Die nach der Zusatzerfindung gefundene Verbesserung besteht darin, an Stelle der Tablettenform besondere Verzögerungsstücke zur Aufnahme des Verzögerungssatzes zu benutzen, deren Länge so gewählt ist, daß sie ebenfalls nur den Leerraum der Sprengkapselhülse ausfüllen und nicht darüber hinausragen. Die Erfindung hat ' gegenüber dem Hauptpatent den Vorteil, daß nach der Entzündung ein wesentlich geringeres Gasvolumen und auch eine niedrigere Temperatur entsteht. Hierdurch können einmal die Entgasungskanäle kleiner gestaltet werden, das andere Mal tritt nicht so leicht eine Erhitzung der Sprengkapselhülsen ein, wodurch leicht Frühzündungen verursacht werden können. Während beim - Hauptpatent verschließbare Entgasungslöcher seitlich angebracht sind, laufen bei der neuen Einrichtung die Entgasungskanäle in mehr zweckentsprechender Weise längsseits des Zünders.The space to hold the tablets and powder sets in the detonator capsule is, according to the main patent, the normal empty space that every detonator can hold the fuse must have. The improvement found according to the additional invention exists in it, instead of the tablet shape, special delay pieces to accommodate the To use delay set, the length of which is chosen so that they also only Fill in the empty space of the detonator shell and do not protrude beyond it. the Invention has' over the main patent the advantage that after ignition a significantly lower gas volume and a lower temperature result. Through this once the degassing channels can be made smaller, the other time it occurs The detonator shells are not so easily heated, which can easily lead to pre-ignition can be caused. While with the main patent closable degassing holes are attached to the side, the degassing channels run in the new facility in a more appropriate manner alongside the detonator.
