Method of development of an inclined lying productive stratum of minerals

The invention pertains to mining and oil and gas output and can be used, more specifically, for underground borehole leaching of a salt layer lying under a certain slope. The method makes it possible to increase the efficiency of the development due to a more complete study of the inclined mineral deposits (salts, high-viscosity oil, uranium and copper ores, etc.).

Device for correction of kyphoscoliotic deformity of spine in children

The utility model pertains to medicine and can be used in traumatology, orthopaedics and vertebrology. The device for correction of kyphoscoliotic deformity of spine in children contains two elastic plates, a block for connecting plates with vertebrae, consisting of C-shaped hooks, with screw-like elements, U-shaped grips with one protrusion and fixing nuts in the heel. The device provides a more stable and even distribution of the load on the plates, a reduction in the resistance of the device blocks to the growth of the spine, and is also less traumatic for surrounding soft body tissues.

Orthodontic typodont

The utility model pertains to medical anatomical models, more specifically to orthodontics and orthodontic devices. The orthodontic typodont contains a model of the upper and lower jaw with a plastic cap, teeth, braces and an orthodontic arch, while the dental holes of the artificial paradont formed in a plastic base are filled with pre-melted wax. The typodont makes it possible to study the biomechanics of tooth movement in three directions under the influence of superimposed orthodontic equipment and the training of orthodontists in the practical skills of fixing orthodontic equipment with control of the movements of teeth after it is applied.

Method for extracting rhenium from molybdenum-containing solutions

The invention pertains to the field of hydrometallurgy of rare metals, more specifically to a method for extracting rhenium from molybdenum-containing solutions. The method includes the sorption of rhenium from molybdenum-containing solutions by anion exchangers of the gel structure. The sorption is carried out on anion exchangers with a pore size of 2.5-6.0.10-10 m, which do not contain tertiary amino groups and quaternary ammonium groups. The technical result is an increase in the selectivity of rhenium extraction.

Device for distal displacement of permanent molars

The utility model pertains to medicine, more specifically to the orthodontics and orthodontic devices and can be used to treat violations of the position (mesial displacement) of the lateral teeth. According to statistics, 65% of dentoalveolar anomalies in cases of distal occlusion are associated with mesial displacement of the patients lateral teeth, which leads to shortening of the dentition, development of congestion or pathological protrusion of the frontal teeth, which are treated by removing premolars or by distalization of molars. The model contains an orthodontic implant, an active and preformed stabilizing wire arc, one end of which is fixed to the supporting tooth, the free end of the active arc is fixed to the moved tooth, and the free end of the stabilizing arc is fixed to the orthodontic implant. The active arc is a loop made of an alloy of superelastic titanium nickelide, having a circular cross-section 0.4 mm in diameter, and the stabilizing arc is made of a steel alloy and has a rectangular cross section. The device allows to improve the interaction of its working parts with the patient's dental row, and to simplify its manufacturing and installation into the oral cavity.

Method for leaching minerals from a productive formation

The invention pertains to mining. The method for leaching minerals from a productive formation includes drilling of injection and extraction trunks, feeding the leach solution through a pouring barrel and pumping the productive solution through a extraction unit. Drilling of the pouring and pumping trunks is carried out in one direction, placing the pouring bays under the poured ones, while drilling the next pair of pouring and pumping shafts, drilling the next pair of barrels clockwise from the first pair in 45 ° increments, and feeding the leach solution after drilling the next pair of barrels, after pumping out the productive solution, the used trunks are muffled and they drill new trunks counter-clockwise with a step from the first pumping and pouring barrels at 22.5 °, following - at 45 °. In addition, when the ore formation is inclined, the drilling and pumping trunks are drilled at an angle of occurrence of the ore formation.
