The invention relates to the design and production of a piece of firearms and can be used for marking the chamber and barrel of a small arms manufactured in small batches.

Known for marking weapons (RU patent 2148769, 2000), with accommodation on the inner surface of the barrel inorganic marking coatings, ensuring the implementation of a set of microelements in the side surface of the bullet when passing it on to the target during the shot, allowing by chemical analysis of the surface of the bullet, and surfaces in contact with the bullet after firing to determine the qualitative and quantitative composition of the established elements and, therefore, the trunk from which a shot was fired.

This system of marking of the trace elements are not suitable for identification of weapons on the sleeve.

Known also design a rifle (RU patent 2212609, 2003). Known design rifle includes on the inner surface of the barrel, at least one marking element, leaving the shot on the pool traces that can be identified as individual code of the trunk, and as specified marking element used field between adjacent grooves whose width different from the width of other fields, and edit the imposition of the width ranges from 2.8 to 5.7% of the width of the field, defined as the difference between the circumference of the barrel and the total width of the grooves, divided by the number of fields.

A disadvantage of known construction rifles should recognize the impossibility of identification of the weapon barrel.

A known method of applying identification marks on rifles (US patent 4175346, 1979). Proposed to be applied to the inner surface of the barrel rifled weapons additional marking elements, leaving traces on the pool, which can be identified as individual characteristics of the barrel rifled weapons.

A disadvantage of known construction admittedly not take into account the impact of the additional marking elements on ballistic weapons, in addition, in this embodiment, the weapon cannot be identified by empty sleeve.

There is a method of identifying weapons (Kustanovich S.D. Forensic ballistics. M. "Legal literature", 1956, p.24-27). According to a known method carried out comparing two bullets and two sleeves, one of which obviously westralian of the test weapons, and the second is presumably westralian of the test weapons. The comparison is carried out, in General, the number and width of traces of the fields of the grooves of the bullet, the direction and angle of inclination, and also by comparing the appearance of the shells, their characteristic dust, shock, scratches the n and defects. In addition, compare the shape and size of the individual tracks, the configuration of the projections and depressions, as well as their mutual arrangement - i.e. the elements inherent in the individual barrel and chambered rifle.

The disadvantage of this method should recognize the need for the expert ballista firearms (or bullets, or shells)that can be used as an element of comparison. In their absence, the examination cannot be performed.

The applicant is not known to the system detection agents to identify small arms.

The technical problem to be solved by the present invention is to provide opportunities weapons marking, preferably produced in small batches.

The technical result obtained by the invention is to provide for the identification of weapons of shot sleeve with the previously completed marking elements.

This technical result is achieved by the use of means for marking applied on the inner surface of the chamber and contains a mixture of three inorganic substances, which are able to emit radiation in the wavelength range from 460 to 680 nm is irradiated by radiation with a wavelength of 800 to 1200 nm, and decree the major inorganic substance selected from the group containing substances, one of which has the ability to emit radiation in the blue range, one in the green range and one in the red range, the ratio of these substances is known in advance, as set by mixing the components of the mixture before application. The mixture may additionally contain components that increase its adhesion to the metal surface. Application can be made either from solution or by spraying. As a substance capable of generating radiation in the blue range, use fluoride divalent lead or oxide of tetravalent germanium, doped with thulium or ytterbium; as a substance capable of generating radiation in the green range use La2O2S, activated with ytterbium or erbium; as a substance capable of generating radiation in the red range use Y2O3-YOF, activated with ytterbium or erbium, and Y2O3-YOCl, activated with ytterbium or erbium. However, it is possible to use other substances that meet the criteria defined above. Previously on the surface of the chamber may be caused to the sublayer, in particular polymeric liner that increases the adhesion of the above-mentioned mixture of fluorescent substances. Also it is possible to increase the relief is and the surfaces of the chamber, in particular, by making many small cuts abrasive processing.

It was established experimentally that such marking leaves a fluorescent label on the sleeve, especially cardboard, and the pool in the exercise of not less than 400 shots.

Hereinafter the invention will be discussed using different implementations.

The inner surface of the chamber and the adjacent part of the rifle was coated from a solution mixture GeO2activated Tm and Yb, La2O2S, activated Er and Yb and YF3activated Er and Yb, and these substances were used in a mass ratio of 1:1:1. After applying this mixture, and it dries completely made a test shot. Shot sleeve and the bullet were processed optical radiation with a wavelength of 800 to 1200 nm with subsequent registration of the luminescent emission of trace quantities of this mixture luminescent substances and location of the results obtained in the data Bank of the company, which produces the specified weapon. When determining the weapons available on the liner or pool their coverage of the specified optical radiation with a wavelength of 800 to 1200 nm with the registration of the fluorescent radiation. Comparing the results with the existing database values, define a specific weapon.

At the bottom h is the terrain of the inner surface of the barrel shotguns flush was reinforced polymer liner with a developed surface. On the specified liner and the adjacent portion of the barrel of a rifle struck a mixture of the same substances, but taken in the ratio 2:1:1. Similarly was determined response luminescense emission of these substances with the shot sleeve. The results were placed in the database.

For marking on the inner surface of the barrel shotguns were used vacuum deposition of a mixture of these substances, taken in the ratio 9:4:6. Similarly was determined response luminescense emission of these substances with the shot sleeve. The results were placed in the database.

The proposed tool will allow marking of newly manufactured and existing instances of weapons. The lack of sophisticated equipment used for marking, and for its reading, leads to simplification of the process of marking and to simplify the registration process luminescense signal, which allows to make a conclusion about the use of specific weapons. The possibility of changes in the composition of the mixture of substances can virtually do not limit the number of marked units.

1. A means of marking weapons, characterized by the presence of damage on the inner surface of the chamber fluoride compounds of divalent lead or oxide of tetravalent Germany the Oia, activated with thulium or ytterbium, capable of generating fluorescent emission in the blue range, La2O2S activated with ytterbium or erbium capable of generating radiation in the green range, and Y2O3-YOF activated with ytterbium or erbium, and Y2About3-YOCl activated with ytterbium or erbium capable of generating radiation in the red range, the ratio of these substances specified in advance.

2. The tool according to claim 1, characterized in that the mixture is used for coating from solution or by spraying.

3. The tool according to claim 1, characterized in that the mixture additionally contains components that enhance its adhesion to the metal surface.
