GAINE MOULEE DE SECURITE POUR EXPLOSIFS.
La présente invention se rapporte aux gaines dites de sécurité composées de matière inerte, en général de sels fusibles constituant au moment de l'explosion un écran protecteur pour l'explosif qu'elles renferment.
L'un des buts poursuivis est d'augmenter la sécurité en gainant également le ou les fonds et à cet effet la gaine se présente sous la forme d'un cylindre creux fermé à une extrémité.
Cette gaine aura de préférence été traitée de manière à être ren- due rigide par tous moyens appropriés.
Par exemple on,,pourra prévoir comme décrit et mis sous protection dans la demande de brevet N 393281 du 11.6.1951 au nom de la demanderesse l'addition à la matière inerte d'un composé durcissant-et de filaments tels que soie de verre, fibre d'asbeste, poils; etc.
Une telle gaine contiendra par exemple du bicarbonate de soude comme matière extinctrice.
Le dessin ci-joint représente à titre d'exemple une gaine réalisée suivant l'invention.
Sur ce dessin 1 désigne la gaine et 2 le fond par lequel la gaine est fermée à un bout.
Dans ces conditions l'explosif représenté en 3 pourra être intro- duit directement dans la gaine sans interposition de papier. La fermeture à l'autre extrémité pourra se faire par une simple rondelle 4.
Une caractéristique supplémentaire de l'invention est que le noyau d'explosif peut affecter du côté du fond de la gaine la forme d'une charge creuse et à cet effet on peut prévoir, dans le fondy un cône 5 en une matière appropriée.
Cette charge creuse a pour effet d'augmenter la vitesse de trans- mission de la détonation d'une cartouche à l'autre et d'éviter les mines dites "débourantes".

MOLDED SAFETY SHEATH FOR EXPLOSIVES.
The present invention relates to so-called security sheaths composed of inert material, in general of fusible salts constituting at the time of the explosion a protective screen for the explosive which they contain.
One of the aims pursued is to increase safety by also sheathing the bottom (s) and for this purpose the sheath is in the form of a hollow cylinder closed at one end.
This sheath will preferably have been treated so as to be made rigid by any suitable means.
For example, as described and placed under protection in patent application N 393281 of 11.6.1951 in the name of the applicant, it will be possible to provide the addition to the inert material of a hardening compound and of filaments such as glass silk. , asbestos fiber, hairs; etc.
Such a sheath will contain, for example, baking soda as an extinguishing material.
The accompanying drawing represents by way of example a sheath produced according to the invention.
In this drawing 1 designates the sheath and 2 the bottom by which the sheath is closed at one end.
Under these conditions, the explosive shown in 3 can be introduced directly into the sheath without the interposition of paper. Closure at the other end can be done with a simple washer 4.
A further characteristic of the invention is that the explosive core can take the form of a shaped charge on the side of the bottom of the sheath and for this purpose it is possible to provide, in the base, a cone 5 of a suitable material.
This shaped charge has the effect of increasing the speed of transmission of the detonation from one cartridge to another and of avoiding so-called "flushing" mines.
