    The interplay between the rollers 21 and their diameter is selected so that the sample (core) 22 can fit on them, the diameter of which can vary from a few centimeters to several decimeters. Different core diameters 22 are marked on a scale of 19, each division 23 of which corresponds to one exact diameter of the core. The core 22, which may be solid, but most often consists of several pieces stacked together, is kept compressed laterally to avoid relative displacement of the pieces with two clamping rods 24, which can at one end move along a guide 25 fixed on the surface of the table 1 parallel to the horizontal axis of the rollers 21, the other ends of the rods 24 are equipped with rollers 26, and the movement of these rods 24 is carried out with the help of small hollow blocks 27 moving. along the guide 25 and each equipped with a screw 28, during which the blocks 27 and, consequently, the rods 24 stop in a certain position on the guide 25, are clamped. Thus, the core 22 can freely rotate, having no possibility to move in the lateral direction, which would lead to the separation of the pieces of which it is composed. Moisturizing means are provided in the tank 20, which are a tube 29 with small spray holes 30 evenly spaced along the entire length of this tube, and the inclination of the tube is such that it allows the core 22 to be wetted without spraying inside the tank 20. Tube 29 is mounted below the longitudinal axes of the rollers 21 and is fed at one end from a source (not shown) of the liquid, in this case water at a slight pressure, which at the other end is withdrawn from the said tank. Spraying water onto the core in combination with the action of the rollers 21 makes it possible to create a thin water film on the core. Supplying water under pressure not only cleans the lateral surface of the core, it also fills small holes, always appearing on the surface of the core, so that the surface becomes even and smoother as possible to ensure the best quality.

    photos. The water supplied to the core 22 takes on the appearance of a thin film under the action of the rolling rollers 21. The formation and thickness of the thin film are constantly provided by the rotation of the rollers 21 provided by a synchronous motor 31 and a toothed belt 32 passing through the weaves 33 mounted axle rollers
    21, The constant presence of a thin water film over the entire time of photographing makes it possible to increase the luminance coefficient or the coefficient of reflection of the core surface, which is the ratio between the emissivity of a body and the emissivity of an equivalent black body. An increase in the surface reflectance entails an increase in the contrast of the details of the core surface and improves the quality of photographs, since for the system the core surface becomes equivalent to a polished surface.
    Lighting the photographed core
    22 is provided with two oriented lamps 34 mounted on
    two brackets mounted on the frame 7. Preferably, the lamps 34 are oriented so as to give light fluxes falling on the core at an angle of 45 ° so that the specular reflection does not fall into the slot 35 provided in the photographing node 5.
    A barrier 36 is provided in the protective casing 9, dividing the internal volume into two compartments 37 and 38. In compartment 37 a conventional camera 39 is located adapted for photographing the surface of cores. In compartment 38 there is a synchronous motor 40 fixed on the partition 36 and four end pulleys 41 ( shown two). The transport unit (trolley) 42 is moved on the swath tracks 43 secured on the partition 36 and receives a photographic plate or flat film, designated 44, which is a standard plate or film. The plate is inserted into the casing 9 and installed on the trolley 42 through a window 45 formed in the front wall of the casing 9 (Fig 2).

    Trolley 42 contains two pins 46 for engaging small tension springs.
    47, to which the cable ends are fastened
    48 serving to move said carriage 42 and winding onto pulleys 41. Two openings 49 and 50 are made in the partition 36. A slit 35 and an exposure window 51 are provided opposite these openings. The light-shielding removable mask 52 longitudinally moves in a slot 53 formed in the partition 36 , and contains a vertical shoulder 54, pressed against the closing position by a return spring 55 fixed to the partition element 36. Two pushers 56 rigidly connected to the trolley 42 can abut when moved to the right in FIG. 4 to shoulder 54 so that to set up a mask 52
    in the open position and thus open the exposure window 51,
    The slit 35 is smaller than the window, and consists of a wider 57 and narrower 58 parts. It is located slightly in front of the plane of shooting of the camera 39. Part 58 includes a diverging portion and a converging portion (not shown). The slit 35 serves to provide an even illumination of the plane of the photographic plate 44 and to obtain a constant illumination along the image forming the photographing core. Thus, the same amount of light energy is obtained along the entire generator, which allows you to further use the digital image transfer system. It. It is important that, in the image plane, it is necessary to compensate for the lateral change in illumination caused on the one hand by the irregularity of the illumination / core forming and, on the other hand, the scattering introduced by the lens of the apparatus 39 depending on the angle of the field.
    The device works as follows.
    Pieces of core or solid core are placed on rollers 21 so as to form a single core 22, after which the latter is stopped in the lateral direction with rods 24. Since the core diameter 22 was previously measured, the handle 17 is manually rotated in order to align the mark 18 with division 23
    scale 19, corresponding to the diameter of the photographed core 22. When the knob 17 is rotated, the rod J3 of constant length moves and, therefore, the focusing focus 15 and the table 14, which are rigidly connected to the rod 13. After this, the node 5 is lowered ( Figure 2 shows the dashed line). The knot is held in this lower position by means of a latch 59, which is inserted in slot 60, mounted on frame 7. Photo plate 44 is placed on trolley 42. After these adjusting and charging operations, the engine 31 is turned on, ensuring that the core surface is prepared thin water film. The release of the node 5 is carried out by pressing down the organ 8 of the grip, as a result of which the latch 59 comes out of the socket 60; Under the action of a heavier counterweight 10, the node 5 without any assistance rises up to the stop in the stopper 15. As a result, the camera lens is not only focused on the sharpness of the table 14, but also on the core 22 due to the corresponding installation of the stop 15. Automatic aiming The sharpness of the lens makes it possible to obtain a clearer image of the vernier core 22 regardless of its diameter. A first survey is carried out in which the table 14 is photographed and the engine 40 is actuated so as to move the carriage 42 to the right in FIG. 4. As a result of the movement, the mask 52 also moves to the right under the action of the pushers 56 resting against the shoulder 54. As the window 51 is open, the aperture of the camera 39 is opened with a delay of, for example, 1 / J25 s. After the end of the first exposure, the engine 40 is driven in the opposite direction to move the carriage 42 to the left. Since the mask 52 is no longer being pushed by the pushers 56 and the return spring 55 acts on it, the mask returns to the closing position of the window 51, Two engines 40 and 31 operate synchronously so that the linear speed of the carriage 42 is equal to the speed of rotation of the rollers 21 and, therefore, vrate speed10

    no core 22 that rotates around its axis without slipping. While the plate 44 is moving in its plane in front of the fixed slit 35, the lens of the camera 39 forms an image of one core generator 22 on said slit 35, which is centered on the optical axis and is parallel to the generator of the core being photographed. The selection of the rotational speed of the core 22 depends on the numerical aperture of the lens and on the illumination, but the device according to the invention makes it possible to operate with a constant illumination intensity and a variable numerical aperture. Similarly, since the lens flips the image in the direction of the fixed slit, the choice of the direction of rotation relative to the direction of the longitudinal movement of the carriage 42 should be made so as to flip the image in the direction perpendicular to the fixed slit.
    In addition, the movement of the plate 44 is carried out so that the core 22 is photographed in one and a half turns, which allows reducing the predominance of the original generatrix and eliminating edge effects on the subsequent numerical transmission.
