PATTERN REGISTRATION

Title:

Field of use:

Waterproof receptacle for transfer charges, preferably in cutting charges.

The innovation concerns a watertight receptacle for transfer charges, preferably in snow loads.

Purpose:

Transfer charges are charges made from compressed high-performance explosives without built-in detonators, which are used to safely detonate relatively insensitive explosive charges serve. Cast TNT charges cannot be ignited with certainty, for example, by a detonator alone.

Blasting sludge, which is not sensitive to capsules, is one of the explosives with Transfer charge must be ignited. These transfer charges must be built in be that they are insensitive in the military temperature range, in addition should not allow water or moisture to penetrate the transfer charges.

'702647 06/30/77

The receptacle for the transfer charge must be designed in such a way that a detonating transfer charge will detonate the adjacent or in the immediate vicinity explosive charges with certainty. The ability of the transfer charge for transmission to the explosive charge is called the "coefficient of detonation transmission ¹¹ (transmission coefficient de la d detonation) CTD, and designated numerically expressed as the arithmetic mean of three consecutive positive and negative results.

State of the art:

It is known, pressed cutting charges to wrap it in paper and insert it into the main explosive charge. Furthermore is it is known to use transfer charges in a thin-walled metal pot, wherein The end of the tin pot is provided with a thread for screwing in an ignition agent is. In the known designs, an anchor nut is glued into the sheet metal pot and the tin pot then closed with a self-adhesive plastic film.

State of the art criticism:

These designs have the disadvantage that they are not waterproof and that they today's demands made during the testing of military equipment, as well as the Conditions for environmental influence, do not meet.

7702647 3n.O6.77

The use of a so-called anchor nut (j_y in the metal pot for the transfer charge also has the disadvantage that the transfer is prevented from charge to charge or does not take place with the necessary detonation speed.

Task:

The aim of the innovation is to create a watertight receptacle that can hold the does not have the disadvantages described and which can be produced easily and cheaply.

Solution:

The object is essentially achieved in that the waterproof receptacle for transfer charges consists of a sleeve with a lid that passes through a snap lock are connected and wherein the sleeve is also connected by a snap lock is fixed in the explosives housing.

Another essential feature of the subject of the application is that the cover has a connecting thread in the center and its extension is designed as a guide tube for a detonator, further that the sleeve in the ground before having an annular recess into which the guide tube of the cover engages and that the sleeve has one or more annular elevations or on the outer surface Has cam.

Achievable benefits:

The advantages achieved with the innovation consist in particular that the receptacle with inserted transmission charge is absolutely watertight and that an ignition delay in the detonation transmission is definitely avoided from load to load.

Description of execution:

The execution is shown in section on the drawing and is described in the following described in more detail. The transfer loading receptacle consists of the Lid 1, the sleeve 2, the receiving channel for the detonator 3, the guide tube for the detonator 4, the round cord seal 5, the cutting charge housing 6, the recess in the cutting charge housing 7, the ring groove in the sleeve (snap lock)

8, the nose on the lid (snap lock)

9, the transfer charge 10, the explosive charge 11, the ring on the case 12, wherein the ring prevents the sleeve from being pulled out of the cutting charge and the annular recess in the bottom 13 for receiving the stirring tube 4, the foam ring 14 which clamps the transfer charge in the sleeve 2.

With the new type of watertight storage container for transfer charges a device is created that fully meets the military requirements and moreover, it is easy and cheap to manufacture.
