Abstract

Ammunition, comprises at least one substance which after firing, is simple to detect and ensures a high recovery rate. Detection is carried out e.g. by the use of UV light.

Description

The present invention describes ammunition that has at least one leading substance contains the typical features after the shot with easy detection Ability and high recovery rate developed.

When examining gunshot marks, especially when shooting determination of clothing, glass panes, car bodies and the like a. will So-called foil impression processes in connection with an energy dispersive X-ray microanalysis or an emission spectral analysis applied. To the Detection of the smoke element lead on skin parts is done with the weft remover determination the X-ray fluorescence analysis used.

The film impression process uses a cellophane film soaked in acetic acid pressed under high pressure on the object to be examined. During the Ab pressure time diffuse smoke elements (lead, antimony, etc.) from the smoke carrier in the cellophane film. If you develop the film after the impression in one Sodium sulfide or potassium bichromate bath, so you get a visible distribution development of the smoke elements.

In the X-ray fluorescence analysis, the sample to be examined is mixed with a high-energy X-rays irradiated. Here the atoms of the sample excited and in turn send out X-rays for the person concerned Type of atom is characteristic. Based on the characteristic X-rays of the Atoms of a particular element can be determined whether that element is in the sample is contained (e.g. the lead smoke element on a part of the skin).

This method has previously been used for the investigation of bullet traces from ammunition with primers containing lead, barium and antimony compounds (SINOXID® ignition kits) to which the previously described procedure is matched was. In particular, the easy retrieval of the lead element gave the Ver drive high security.

This applies to the determination of shot traces after use of weapons in Strafta accidents or self-defense both for the shooter and the victim.  

In the course of the demands to reduce environmental pollution with toxic substances, a replacement of the lead compounds in igniter sets was particularly sought:
In order to meet these requirements, the applicant developed SINTOX® ignition kits. These primers are required if the indoor air must not be contaminated with lead, antimony or barium-containing combustion products when shooting in closed shooting ranges.

Diazodinitrophenol is used as the initial explosive. Tetrazen is called Sensitizer needed. Special forms of zinc pero serve as the oxidizing agent xids. In addition, the igniter metal powder, z. B. titanium.

The residual content of lead, barium or antimony compound is for the primer conditions at <0.01%. Zinc is emitted as harmless zinc oxide.

As an additional measure, the lead cores of the SINTOX® ammunition were given metal covers.

Since in particular the components of the An Ignition rates are important, were shot attempts with this ammunition with the aim of investigating the composition of the powder smoke and the main forensic techniques for examining gunshots traces of the newly developed ammunition to check their applicability.

With the help of emission spectral analysis and X-ray diffraction, the Ele elements and components of the powder smoke are differentiated. In optical The spectrum includes the chemical elements zinc, titanium, copper and iron.

The detection of the elements is possible, but the reliability of detection has been improved earlier investigations not achieved because these elements are not typical and e.g. B. on textiles, colors and the like a. m. are found too often. So there is the problem of the uniqueness of the evidence.

The object of the present invention was therefore to prepare ammunition places that develop easily detectable and typical features after the shot. In particular, such ammunition should be provided that does not lead  releases combustion products containing timon or barium, but after Shot easily detectable and typical features developed.

This object was achieved according to the invention by the addition of lead substance zen to ammunition, the typical identifying features after the shot with lighter Develop detectability and high recovery rates.

Non-toxic elements of the peri odensystems and their connections, insofar as they are thermally stable, e.g. B. from the Reaction damage condensable and compatible with the components of the Muniti on are used. The criteria that these lead substances beyond have to meet are easy, clear detectability and a high How discovery rate. Examples include zircon, the rare earth, in particular other lanthanum, cerium, praseodymium, terbium, dysprosium, ytterbium or gadolinium and their compounds, for example their oxides. In addition, you can also such substances as lead substances in the sense of the present invention are used that are clearly identifiable under UV light or otherwise, as long as they meet the above criteria. Mixtures of these lead substances zen can also be used according to the invention.

Since the addition of these lead substances is only intended to serve as a shot of lead-free and barium-free ammunition and, for example, the to assign used ammunition to a specific manufacturer on the on the other hand, the property of the ammunition by the lead substances does not adversely affect The amount of lead substances added is measured in this way that this goal will be achieved. In general, a few mg- Quantities.

To perform an extended gun range and weapon identification too can, according to the invention, vary the particle size of the lead substance zen can be provided.

The lead substances according to the invention can be components of, for example, the Ignition charge, the propellant powder, the tracer or tracer ignition be. But you can also work into covers or varnishes the z. B. applied to primers or covers.  

The addition of the guide elements according to the invention makes it possible to get shot marks reliable testing of lead and barium-free ammunition and for example assign the ammunition used to a specific manufacturer. Through the Varying the particle size can also be an extended shot removal and Weapon identification is made possible.
