Explosive or detonation cartridge, in particular for a sound wave generator

The invention relates to an explosive or detonation cartridge that is used in a sound wave generator, as described in French patent specification 1 422 837, is to be used.

According to the invention, this cartridge is characterized by • a cartridge body consisting of a destructible material made up of a cylindrical tube and a cylindrical jacket, which are concentric with each other and firmly attached to each other and by being separated from each other by an annulus,

the jacket being rounded near one end Part under limitation, the opening space at one end of the tube and in a tubular, the Pipe extending part ends; and by a first charge of less sensitive explosive in the annulus at the bottom of the shell, which is held by a tight plug made of destructible material; and by a second The charge of highly sensitive explosive assigned to the first charge.

For example embodiments of the cartridge are now intended will be explained in more detail with reference to the accompanying drawings, in which

Figure 1 is a schematic illustration of the cartridge;

Fig. 2 is a section through a first embodiment of the invention;

Fig. 3 shows a section through a second embodiment and

Fig. 4 shows a section through a third embodiment according to the invention.

According to FIGS. 1 and 2, the cartridge has a body made of 109828/0051 ^ _{0 0 RlQINAL}

Insulation material that is quite stiff and destructible, such as plastic. The cartridge body consists essentially of an inner tube 1 and an outer jacket 2 concentric thereto, which for example a single part is firmly connected to one another by molding are.

The inner tube / is cylindrical over its entire length surrounded by the jacket 2 and the jacket, which is cylindrical over most of its length, is close to it one end, the so-called. Nose of the cartridge, a rounded part 3, which is present between the jacket and tube 1 Space on one side and ends in a tubular part 4 extending the tube. In the amount of At the bottom 3, the inner wall of the tubes 1 and 4 has a throttle point 5. The jacket 2 has on the tubular one Part 4 opposite side a funnel-like calibrating widening the head of the cartridge forming Part 6, which ends in a marginal edge 7.

Inside the cartridge is a charge 8, consisting of a less sensitive explosive, for example nitrate explosive, the another weaker charge 9 made of highly sensitive explosives, the so-called "explosive relay", for example pentrite, is assigned. The explosive

109828/0051

The relay can be in the form of a ring surrounding the tube 1 and arranged in the mass of the charge 8. This explosion process with the assignment of charges of different sensitivity is known per se. Due to the structure of the cartridges according to the invention, this assignment of charges of different sensitivity is intended inside the cartridge may be brought about that a rapid introduction of this Guarantee loads with maximum security. The explosive material is at the bottom of the mantle in the room arranged between tube 1 and jacket 2 and by a waterproof plug 10 made of destructible material (for example plastic) held.

An electric igniter 11 is inserted into the inside of the tube at the time the cartridge is to be used introduced by being at the level of the explosive charge on the one hand through the throttle point 5 and on the other hand a rigidly connected to the tube 1 stop 12 made of deformable plastic is held in such a way that the Introduction of the detonator is enabled. The lead wires to the igniter 11 are protected by the tubes 1 and 4.

The inner diameter of the throttle point 5 is slightly larger than that extending in the tubular part 4

109828/0051 ~ ⁵ "

Leads to the igniter, the one in the tubular part The lead section included is stripped or stripped.

By this embodiment of the cartridge its use is very simplified, since it is now sufficient to the Detonator into the Introduce tube 1 until it comes into abutment against the throttle point 5 at the time of its use.

Fig. 3 shows a second embodiment of the cartridge according to the invention. Here, the explosive relay 9 is in Inside the tube 1 is arranged above the igniter 11, with which it is connected by a ring 13 made of destructible material is. It is therefore extremely easy to insert the overall arrangement, consisting of the elements 9, 11, into the tube 1 and 13 simple at the time the cartridge is used to introduce.

Between igniter 11 and throttle part 5 you can also Insert a Xaolieracheibenring 14 made of flexible material.

In a third embodiment of the cartridge according to the invention - shown in Fig. 4 - has the inner tube 1 of the cartridge does not have the same diameter over its entire length. The one closest to the cartridge nose Part of the pipe has an inner diameter of the - leaving a game - the diameter of the Detonator 11 corresponds to and a shorter length than the latter has. A part 1b with a larger diameter of the tube 1 is provided as an extension of the section 1a and forms a circular shoulder with this 15 in the amount of this change in diameter.

To load the cartridge, an initial charge is made from little Sensitive explosive introduced - as in the above cases - to the bottom of the shell in the annular space between tube 1 and dumbbell 2 and is made of destructible by a waterproof plug 10 Material (such as plastic) held.

The second or relay charge 9 of sensitive explosive is provided in the form of an annular disc, whose Inside diameter on the outside diameter of the detonator and its outside diameter on the inside diameter of the widened part of the tube 1 is matched. At the moment the cartridge is used,

the relay charge is pushed onto one end of the igniter 11, the overall arrangement of the relay-igniter is left then slide into the tube 1 until the relay charge 9 comes into abutment against the shoulder 15.

The relay charge 9 is near one end of the

Detonator 11 preferably in a zone near the " active igniter part arranged at such a height that when the relay rests against the shoulder, the the other end of the detonator is practically at the level of the mantle floor is located.

Such a design of the cartridge results in the cartridge preparing more quickly at the time of use can be achieved and that greater security is achieved, since the relay charge is only introduced at the last moment |
