Description

This utility model belongs to the tools and equipment for numismatists and jewelers. Its purpose is the reliable determination of elemental composition of precious metals and coins, mainly for the confirmation of their authenticity and the protection against counterfeiting, and it can be used both privately, as well as in goldsmiths, studios and exhibitions.

Currently, the authenticity of jewelery made of precious metals and coins, hereinafter in the text - (jewelery) is determined by visual and technical methods. Visual methods require the assessment of the authenticity of jewelery by their external examination, as well as the subsequent comparison with catalogs and other data carriers. These methods are labor intensive and characterized by lack of reliability. Technical methods provide a more reliable result, but require special equipment such as microscopes and eyepieces, and also require comparisons with catalogs and other data carriers.

The device after DE 20 2014 009 752 U1 requires multiple weighing of jewelery with subsequent data comparisons using specialized spreadsheets and other sources of information This is a labor-intensive process that requires specialized knowledge from the user. The technical equipment required in this method for determining the authenticity and composition of jewelery (coins) must be precisely calibrated and regulated. It follows that this device is not very suitable for practical use

The method after DE 10 2010 018 147 A1 is based on complex algorithms for data analysis and requires special computer software. It follows that this method is also not very suitable for practical use.

The aim of this utility model is to provide a simple and user-friendly device for everyday use, which makes it possible to determine properties of products made of precious metals and coins (hereinafter referred to as "text"), and through simple tools for measuring weight, volume , Density and magnetic properties can be used.

In order to realize the set goals, the apparatus for determining the properties of products of precious metals and coins, which includes an electronic balance, according to the protection claims 1 by a frame on which an electronic balance is mounted, and by holders with threaded holes on the brackets on the frame are tied to side supports, at the top of which a bridge for the holder of the jewelers to be examined is mounted. Below the bridge, a plank is fixed by two thumbscrews, which can be turned and fixed vertically and horizontally, whereby at the first stage the measurement the plank is fixed vertically
Weighing jewelery is done in a dry and a wet state. When weighing in the wet state, a glass of water and a holder that compensates for the weight of the jewelery are placed in the scale's measuring platform
Thus, in the first stage, the measurement of weight, volume, and by the buoyancy method also on the density of jewelery. As a result, data are determined which are necessary for the determination of properties and the authenticity of the jewelery

According to the protection claims 2, the device according to claims 1 characterized in that for the determination of the magnetic properties of jewelery a measuring magnet is used, which is connected by a threaded adjusting screw with the frame and mounted on the measuring platform, without the plank touch. The plank is fixed in the horizontal position, while the jewelery is placed on the plank

This allows the second stage to measure the magnetic properties of the jewelery, that is, additional data for the determination of properties and the authenticity of the jewelery is determined.

The process behind the determination of properties of jewels made of precious metals and coins is carried out in several stages. Therefore, in the following description, the structure of the apparatus and its mode of use will be explained at each stage.

At the first stage ( 1 and 2 ) determines the weight, the volume and, by the buoyancy method, the density of the jewelery.
The device contains a frame ( 1 ) on which an electronic balance ( 2 ) and mounts ( 3 ) The brackets ( 3 ) have threaded openings ( 4 ). By two screws ( 5 ) with wings ( 6 ) are to the brackets ( 3 ) on the frame ( 1 ) Side supports ( 7 ). The upper part of the side sockets ( 7 ) is by screws ( 8th ) with the bridge ( 9 ) used for the attachment of the bracket ( 10 ) for the jewelery to be examined ( 11 ) - (hereinafter text - jewelery ( 11 )). In the lower part of the bracket ( 10 ) is a platform ( 12 ) for the placement of jewelery ( 11 ). Below the bridge ( 8th ) is by two thumbscrews ( 13 ) a plank ( 14 ) The plank ( 14 ) can be rotated and fixed in vertical and horizontal position When performing the first stage, the measuring platform ( 15 ) of the balance ( 2 ) a glass ( 16 ), which are filled with water ( 17 ) is filled.
In carrying out the first stage, the jewelery ( 11 ) in the dry state on the balance ( 2 ) and the weight is entered in a table (18) - (not on 1 - 4 shown)
Subsequently, on the balance ( 2 ) by the buoyancy method a weighing of the same jewelery ( 11 ) carried out. For this, the measuring platform ( 15 ) of the balance ( 2 ) a glass ( 16 ), which is filled with water ( 17 ), whereby on the bridge ( 9 ) the holder ( 10 This places the plank ( 14 ) fixed in vertical position and does not prevent the placement of the bracket ( 10 ), the weight of jewelery ( 11 ) compensated. The platform ( 12 ) gets into the water ( 17 ), whereby they do not cover the bottom or the walls of the glass ( 16 ) touched. The information of the balance ( 2 ) are reset. Subsequently, on the platform ( 12 ) the jewelery ( 11 ) and read their weight when wet. The weights of jewelery ( 11 ) are entered in the corresponding line of table (18). After the weighing is completed by the buoyancy method, the holder ( 10 ) together with the jewelery ( 11 ) and the glass ( 16 ) from the measuring platform ( 15 ) of the balance ( 2 ) and the device is prepared for the second stage of the measurement
The result of the first stage - the density of jewelery ( 11 ) - is determined by the division of the weight of jewelery ( 11 ) in the dry state by their weight in the water ( 17 ).

At the second stage ( 3 and 4 ), the magnetic properties of jewelery ( 11 ).
For this the plank ( 14 ) using flyscrews ( 13 ) fixed in a horizontal position on the measuring platform ( 15 ) of the balance ( 2 ) becomes a measuring magnet ( 19 ) placed with the frame ( 20 ) by a threaded screw ( 21 ), by which the position of the measuring magnet ( 19 ) in relation to jewelery ( 11 ) is regulated. The measuring magnet ( 19 ) so that he does not put the plank ( 14 ) touched. Next, the balance ( 2 ) and the information is reset. On the plank ( 14 ) the jewelery ( 11 ), the information of the balance ( 2 ) and entered in the corresponding line of table (18).
If further measurements have to be made in the determination of magnetic properties, the jewelery ( 11 ) from the plank ( 14 ) and put again on them, measuring and recording the results is performed again.
The results of the measurements of the first and second stages determine the authenticity of the jewelery.
