The invention relates to a production line for producing composite reinforcing bars. The technical result of the invention consists in increasing the productivity of the line and improving rebar strength. The production line for producing composite reinforcing bars comprises the following equipment mounted in series: a frame with roving bobbins, a levelling device, a drying chamber, a dipping tank with a tensioning device, a squeezer, a bundle former with a winder, a polymerization chamber, a cooling device, a pulling mechanism and a cutting component. The bundle former is designed in the form of two outer rotating tubes with winders disposed thereon. Inside each outer rotating tube and coaxially therewith, there are stationary tubes mounted on retainers and centering bearings, and attached to the ends of said stationary tubes are removable moulding assemblies with apertures corresponding to the standard size of the rebar. After the moulding assemblies, before the polymerization chamber, the reinforcing bars come into contact with one pair of guiding rollers on their outer side and with a second pair of guiding rollers on their inner side in the direction of movement of the reinforcing bars.

The invention pertains to a device for eliminating deviation between the path of a mobile machine and the path of the moved end of an energy chain encompassing at least the energy supply lines for the machine. The device consists of a driver (1) with a maximally limited capacity to transmit forces in the direction between the machine (2) and the moved end (3) of the energy chain (4). The driver (1) is connected both to the machine (2) and to the moved end (3) of the energy chain (4).

Negative contrast agent, particularly for examination of the intestinal tract by the method of MRI, formed on the basis of superparamagnetic iron oxides nanoparticles. The essence of the invention is that the agent comprises of water suspension of clayey mineral and superparamagnetic iron oxides nanoparticles immobilized on the surface of the clayey mineral particles, in the process of which the mutual weight ratio of the oxide to the clayey mineral is 1 : 4 to 15.

The present invention concerns to a set of photovoltaic cells on panels with an adjustable position, where the set comprises at least one movable supporting construction where panels equipped by photovoltaic cells are carried on, a foundation for carrying this movable supporting construction with photovoltaic cells, and a positioning driving device. The foundation (1) is consisting of two stands (11,12), having a different height, where each of them having on its top a supporting place (111,121), adjusted for a rocking coupling with a movable supporting construction (2), this movable supporting construction (2) being created as in longitudinal direction laying main longitudinal beam (21), to which supporting cross beams (23) are fixed in regular relative distances, corresponding the dimensions of the photovoltaic panels (22) with photovoltaic cells, where those supporting cross beams (23) are adjusted for carrying of said photovoltaic panels (22) with photovoltaic cells, and further, the ends of the main longitudinal beam (21) are adjusted for pivoting in bearing places (111,121) of the stands (11,12) of the foundation (1), where in the meantime, the positioning driving device is created as a linear electric drive (3) or hydraulic drive, coupled by a driving mechanical coupling (31) to a movable supporting construction (2) and connected by governing linkage (41) to a governing device (4).
