Explosives package to be mixed at the location of the detonation

The invention relates to an improved form of at the site of Demolition to mix explosives packages, the two explosive components contain.

It is known to manufacture explosives in two parts that by themselves are not explosive * and the two parts then at the site of the demolition shortly before use to one Mixing explosives. Before mixing, the two will Parts stored, transported and otherwise handled separately. Because any part of the explosive is not in itself explosive you do not need to use the same precautionary measures for storage, transfer and handling as in the case of a finished explosive.

In U.S. Patent 2,892,377, packaging particulate ammonium nitrate in a watertight container having a resilient wall at one end is described. The ammonium nitrate is in itself an explosive alone is

but explosive when a liquid fuel is added. To the An injection syringe is used to inject the liquid fuel into the ammonium nitrate through the elastic wall.

U.S. Patent 2,929,325 describes the packaging of particulate! Ammonium nitrate in a first container and particulate] fuel in a second container, which can be combined with the first container by sliding one inside the other. A rubber membrane covering the open end of the inner container, has the task of keeping the two substances separate from each other. At the location of the demolition the two ropes are then telescoped together until a cutting edge is at the closed end of the outer container is located, the membrane pierced. 'To the Mix the two parts of the explosive together and shake the whole thing.

Mixing what is considered a non-explosive liquid ingredient and an inherently non-explosive solid component of a two-component explosive at the location of the detonation is also in the USA patent. 3 419 443. Those described in this patent Explosive components are examples of two-part explosives that are also used in the pack according to the invention can be used.

Cutting edge of the Doras out of contact with the top of the Rifle remains. One of the non-explosive components of the explosive (e.g. liquid hydrazine) is housed in the can. The second explosive component (e.g. powdered Ammonium nitrate) is stored in a special container (e.g. a other plastic bottle) brought to the site of the detonation. Just before use, the cap is unscrewed from the pack and the second explosive component is placed in the bottle poured into the space above the can. Then the bottle cap put on again and a downward pressure exerted on the cap, so that the rare walls of the bottle bend and the spike is pushed downwards and pierced the top of the liner. The bottle is then tilted and / or shaken so that the two explosive * Thoroughly mix the ingredients together.

The invention also relates to the details of the Mixing bottle and an explosive device, which consists of the mixing bottle and other components, which are described in detail below to be discribed.

To further explain the invention, reference is made to the drawings.

Pig. 13 is a view similar to Pig. 6 and concerns a modified embodiment.

Pig. 14 is a fragmentary view taken on line 14-14 of Pig.

Pig. 15 is a similar illustration to Pig. 6 and 13 and shows another form of training.

Like Pig. 1 shows, the first component A of the explosive AB is housed in a bottle 10. The explosive component B is in the sleeve 12, which is in the lower part of the Mixing bottle 14 is housed. The two components A and B are carefully weighed beforehand and placed in the relevant container 10 or 12 packed. The sleeve 12 is preferably made of an aluminum alloy with the component A, the Component B and the mixture AB does not react,

The component A is _S transported to prevent in a separate from the mixing bottle 14 container to a random mixing of the two components A and B to the explosive AB in the case of damage to the transport container "If the explosive components are, however reached only once at its destination, can one the constituent. Pour A into mixing bottle 14 without any risk, as described in Pig. 2 is shown. This is done by removing the cap 16 from the mixing bottle 14 and the cap 1i8 from the bottle 10 and placing the bottle 10 on the bottle 14j, whereupon component A from the bottle 10 is poured into the mixing bottle 14. This does not lead to the mixing of the two components A and B to form the explosive AB, because component B is still in the hermetically sealed container 12.

The mixing bottle 14 can be transported as a non-explosive unit even if they are already using the two explosive components is charged, since neither of the two components A and B is capable of detonation. Just before using the

209826/0766

The components A. and B of explosives are as follows mixed: the user sets the bottom of hook 14 on a pad and presses the cap 16 downwards. This causes the walls of the bottle 14 to bend and the mandrel 20 is pushed down through the over wall 22 of the container 12. As soon as there is an opening 24 in the wall 22 has formed, the hash 14 is shaken so that the two ingredients A and B mix. If you have the preferred Used explosives according to the invention, this is Shake completely harmless, because the explosives can only be ignited by a detonator.

The cap 18 of the bottle 10 may have a sealing insert, which is designated by 28 in FIG. 9. The cap 18 has a central projection 30 which telescopes into a tubular central portion 32 of the seal 28 is inserted is. The base of the tubular part 32 is attached to the disk-shaped part 34. The disc-shaped part 34 in turn is attached to a frustoconical part 36, surrounding the tubular part 32. To the truncated cone shaped part 36 is followed by an annular upper flange 38.-The upper surface of the flange 38 is located against the inner surface of the top of cap 18 and the lower surface of flange 38 against the upper Edge of the bottle neck.

As FIG. 3 shows, the upper end of the mandrel 20 has recesses 21, which engage precisely in a rounded circumferential rib 23 of the bottle 14 and in this way the mandrel 20 the bottle 14 firmly.

As can be seen from Fig. 1, 3, 6 and 7, the mandrel or the Cutting tool 20 has a U-shaped cross section. The open side of the dome 20 provides a wide inlet, by which the solid explosive component from the bottle 10 can be poured into the bottle 14. As a result of this

form in combination with the "angle formed by the cutting edge 40", the mandrel penetrates. When the cap 16 is depressed, the tip 42 initially only creates a small hole. As the cap is depressed further, the cutting edges on the opposite sides of the tip 42 progressively cut into the top wall 22 of the sleeve until a semicircular incision has been formed which corresponds to the cross-sectional shape of the mandrel 20. At the same time, the tab punched out of the top wall 22 is bent inward into the sleeve 12, which immediately creates a hole in the top wall 22 If the mandrel 20 is open on one side, it does not clog this hole λ , so that liquid can easily flow out of the hole into the space above the sleeve 12.

The mandrel 20 "is preferably made from a flat sheet of metal cut out and then bent to the illustrated, I-shaped cross-sectional shape.

In Pig. 5 and 8, the can 12 'in the bottle 14 is upside down. In other words: its end closed with a lid is directed downwards. The top wall 22 is made in one piece with the side walls of the sleeve 12. The open end of the can (ie, the lower end) is closed by a cover 44 which is attached to the edge of the can 12 \ in a conventional manner.

The bottle 14 can be a conventional plastic bottle, which come with a bottom molded in one piece with the bottle will. During the manufacture of the mixing bottle 14, the bottom is cut off. Then a retaining ring 48 with a radially inwardly curved upper edge inserted into the bottom part of the bottle 14. Thereupon the sleeve 12 is through.the Bottom opening introduced into the bottle 14. The upper edge of the ring 48 engages the edge 46 of the sleeve 12 and

prevents the sleeve 12 from being completely inserted into the bottle 14 can see into it. Then you insert under the sleeve 14 lower holding member 50 into the bottom opening of the bottle 14, which now forms the bottle bottom /. This organ has 50 an annular side wall 52 and a radial wall 54 which abuts the cover 44 of the can 12. The two holding organs 48 and 50, which "are both made of the same plastic as the bottle 14 ′ are welded together at 56 and welded to the side wall of the bottle 14.

As shown in Fig. 3, the mandrel 20 has two upwardly directed Orientation noses or prongs 25. These tines have 25 a size such that they fit exactly into the mouth of the bottle 10 and are used for axial alignment of the mouth of the bottle 10 with the mouth of the bottle 14 when pouring the solid explosive component A from the bottle 10 into the bottle 14.

10 and 11 show a pouring cap 26, which in its Upper wall 58 has two openings. Located in one opening There is a spout 60 and in the other an air tube 62, both of which open into a base 64. The air tube 62 has a top wall 66 in which a small air hole 68 is located. The unit 60, 62, 64 consisting of the spout and Iuf.tr ohr is inserted into the cap from its open end. The base 64 acts as a seal between the mixing bottle 14 and the Cap 26.

An example of the solid explosive _{component A is a mixture of NH 4} NO ₅ and NH ₄ ClO ₄ , and an example of the liquid component B is a mixture of N ₂ H, NH ₄ NO ₅ and H ₂ O. A typical composition is the following:

According to the invention, the side wall of the bottle 14 is translucent. A powdered dye becomes the solid / Explosive component A added or into the interior of the FIacehe 14 introduced over the sleeve 12. The dye is like that i arrange that he mix the two explosive components stains in a bright or deep color when mixed. In this way one can easily see by eye determine whether the sleeve 12 has been pierced and the liquid B has been mixed with the solid component A.

¥ ie Fig. 3 shows the neck 70 of the bottle 14 with a Sealing ring 72 equipped with a round cross-section, which runs around the circumference of the bottle neck 70. This sealing ring 72 is compressed by the cap 16 and seals the inner surface of the cap 16 against the liquid passage, regardless of whether the cap is screwed on tightly or not. S © is a reliable liquid seal between the bottle neck 70 and cap 16, even if the cap 16 is only loosely screwed onto the neck 70.

After mixing, the explosive mixture AB (which is in a liquid state) can be transferred from the bottle 14 to the location be poured where the demolition is to take place. Fig. 5 shows how the explosives AB from the bottle 14 in a Gap 74 is poured in the ground. The explosive AB can also be used directly in the bottle 14. Different Areas of application of the explosive AB outside the bottle are described in US Pat. No. 3,419,443.

- 9 -209826/0766

The explosives AB is made by means of a normal technical Detonator, e.g. a Wr. 8, ignited. Electric detonators or primers can be used. When the explosive AB in the container 14- is detonated the detonator should be at least half immersed in the explosive AB in order to ensure ignition.

Pig. 13 "to 15" relate to modified embodiments the invention.

According to lig. 13 "is made of polyethylene or another Suitable material made hash 14 'from an upper Part 74 and a lower part 76 which are welded together at 78. Before the two parts 74 and 76 are welded together the unit used to produce the finished explosive is inserted into the lower part 76. This unit includes a can 12 ', which is completely closed, and the liquid explosive component contains. The sleeve can be made so that its side walls and its bottom are in one piece, while a lid is held in a conventional manner on the upper edge of the side wall by a bead.

Immediately below the bead 80, a cylindrical sleeve 82 surrounds the sleeve 12 '. The cuff 82 carries two opposing, upright lugs 84 .. At each lug 84, e.g. by means of a rivet 88, the middle one Part of a mandrel 86 attached. The mandrel 86 consists of the upright handle 90 and a lower perforated part 92 which has a pointed end which initially rests on top 22 'of sleeve 12'.

Before use, the solid explosive component A is poured into the bottle 14 'and the cap 16 is put on. then lateral pressure is exerted on the bottle 14 'in the area of the handles 90 of the cutting member. Through this

- 10 209826/0766

The perforation parts 92 are tilted downward under pressure, so that their tips ^{pierce the upper side 22 f of} the sleeve 12 '. Then the bottle 14 'is inverted and / or shaken to mix the liquid explosive component B with the solid explosive component A.

Pig. 15 shows a mixing bottle 14 ″ made of plastic with an externally threaded upper part 94. -The closure part 96 is screwed onto the thread 94. The closure part 96 has a nozzle-like outlet which is normally closed by a cap 98. In this embodiment, it rests the sleeve 12 "just simply on the bottom 100 of the hook 14". On the edge 104 of the sleeve 12 "sit at diametrically opposite locations cutting tools 102. As in the embodiment shown in Figures 13 and 14, each of these cutting tools 102 has one upright handle 106 and a through-hole part 108, which the latter forms approximately a right angle with the handle. A fitting 110 applies the tool in relation to the rim of the liner 12 "fixedly. The operation of this device ή st the same as that according to the apparatus Pig. Yo and 14.
