1. WOWO/2014/169368 - PISTON SEAL23.10.2014
F16J 9/00
PCT/BY2014/000003SEMENOV, AndreiSEMENOV, Andrei
The device relates to general mechanical engineering, and in particular to seals and pistons, and can be used for sealing pistons in cylinders of piston engines, preferably in internal combustion engines. The problem addressed by the proposed invention consists in improving the technical characteristics of piston engines. This problem is solved by forming a cavity in the lateral surface of the piston and arranging a separator for separating flows of working medium in said cavity. Furthermore, a bypass cavity is formed between the separator for separating the flows of working medium and the piston. Moreover, an inlet slot and an outlet slot are formed in the lateral surface of the piston. When the working medium enters the gap between the piston and the cylinder, for example during the working stroke of the internal combustion engine, part of the working medium passes into the inlet slot, passes along the bypass cavity and is ejected through the outlet slot, thereby exerting pressure on that part of the flow of working medium which is moving in the gap between the piston and the cylinder, and thereby reducing the energy of this flow. As a result, the working medium has less energy for breaching, for example, the casing of the internal combustion engine. This makes it possible to reduce the pressure of piston rings on the mirror of the cylinder and/or to reduce the quantity of said piston rings, which results in an increase in the mechanical efficiency of the piston engine and a reduction in the amount of wear to which the parts thereof are subjected.

PCT/BY2013/000011PARTNOV, Yauheni ViktorovichPARTNOV, Yauheni Viktorovich
The invention relates to the field of energy conservation, and more specifically to techniques for producing fuel gas and heat energy, and can be used in various branches of industry, in agriculture, in vehicles, etc. The method for producing fuel and heat energy therefrom includes starting and carrying out a process under normal conditions by supplying a hydrocarbon component and water separately to a process device, igniting a flame, heating the water and transforming it into a spray by atomization, thus generating water vapour, introducing the hydrocarbon component into a reaction zone and mixing it with the water vapour, heating the vapour-hydrocarbon mixture to a temperature at which a hydrogen-containing fuel is formed, and subsequently burning said fuel. The fuel production process is carried out under autocatalytic conditions in the presence of a complex catalyst, which is comprised of the plasma of the flame produced by the burning of the hydrogen-containing fuel and an oxygen-carrier metal in the form of an oxide selected from Αl2O3 or ТhO2 or ТhO2 or WO3 or β-NiO, at a temperature of 800-1000 °С. The concentration of the hydrocarbon component is maintained within a range of 1.46-1.62%, and the residual amount of unreacted hydrocarbon component contained in the reaction products is 0.25-0.40%. For the vapour-hydrocarbon mixture, the excess of water vapour relative to the stoichiometric amount thereof is set in a range of 80:1-95:1. The invention provides a reduction in harmful emissions and an increase in the energy efficiency of the process.

PCT/BY2012/000006KONDRATIUK, Oleksii MikhailovichKONDRATIUK, Oleksii Mikhailovich
Usage: in manufacture of building products from semidry mixtures. Essence of invention: the method includes preparation of molding sand, its loading in a mold, performance of pressing with creation of hollows in building blocks, removal of an as- formed block and transportation according to the manufacturing route. The mold includes an array (1) made in sections, a punch (11) installed opposite to the array (1) and an interchangeable pallet (2), which makes it possible to extrude a formed product without use of the pressing- out mechanism, which makes the mold construction and method of manufacturing building blocks simpler and cheaper.

6. WOWO/2014/008570 - DENTAL IMPLANT16.01.2014
A61C 8/00
PCT/BY2013/000003JOINT STOCK COMPANY "ALTIMED"DOSTA, Anatoli D.
The invention refers to dentistry, in particular, to the group of dental implants intended for the two-step implantation in the alveolar process. The aim of the invention claimed is to protect reliably the implantation area from ingress of the infection from the oral cavity due to the tight connection of the precervical side of the implant with the periodontal tissue. The set aim is achieved in the dental implant with the support to fix the dental prosthesis and the screw part for installation in the bone tissue, as well as with the ring head located between the dental prosthesis support and the screw part, made from the porous three-dimensional structure of the polymeric material and intended for ingrowth of the gum tissues, by means of the fact that the mentioned ring head is equipped with the reinforcing element made as a hollow body of revolution with apertures and located over the ring head.

7. WOWO/2013/181732 - DISK SCISSORS FOR CUTTING SHEET MATERIAL12.12.2013

PCT/BY2013/000004UTEKHIN, Sergej IvanovichUTEKHIN, Sergej Ivanovich
The invention relates to equipment for cutting and processing materials using pressure and can be used as hand-held scissors for cutting sheet metal, non-metal sheet materials, wire, branches, etc., and enables the straight cutting of not-necessarily rigid sheet materials of any length, as well as the cutting of curved lines, by virtue of a design for disk scissors which use the edge of any table as a guide. To this end the body has two walls, one of which is situated in the plane of a side surface of one disk blade and the other being in a plane close to a plane tangential to the cutting edge of a second disk blade, wherein both of these walls form a spacial internal angle. During the process of cutting, one of the blades rolls along the table and the sheet material lying on the table while the side surface of the second blade slides along the surface of the edge of the table. Sheet material is thereby cut exactly along the edge of the table.

PCT/BY2012/000002KHOMCHANKA, Uladzimir ValiantinavichKHOMCHANKA, Uladzimir Valiantinavich
The invention relates to medicine and can be used in surgery, including cosmetic surgery, for example for treating trophic and persistent ulcers, pressure sores, burns, scars, etc., and also for the purpose of rejuvenating biological tissues, inter alia skin, in different locations. Proposed is a method for the renewal of biological tissues with the restoration of the functional properties, characteristics and structure thereof, in which the tissues are subjected to a predetermined degree of mechanical traumatization through the creation, in given areas, of at least one region of interference between acoustic waves emanating from at least two sources and propagating in the tissues which are to be renewed, with the possibility of the subsequent natural regeneration of the biological tissues concerned in the aforesaid areas. Also proposed are various embodiments of a device for the implementation of the above method. In order to achieve the result of the renewal of different biological tissues situated at different depths, areas of micro trauma are created without thermal effects, i.e. without the evaporation or coagulation of all of the overlying tissues, i.e. the regeneration of the tissues occurs without the growth of fibrotic cells, thus making it possible to speak of actual, rather than merely visible, rejuvenation.

9. WOWO/2013/142941 - GAS-TURBINE ENGINE03.10.2013
F02C 3/14
PCT/BY2013/000002BELOUS, Vladimir IosifovichBELOUS, Vladimir Iosifovich
The invention relates to continuous-combustion open-layout gas-turbine engines, and can be used in transport plants, for example, in aviation plants and in power-generating plants, and also as a drive in gas-pumping units. An at least two-shaft engine (Figure 2) comprises a high-pressure combustion chamber (29) and a low-pressure combustion chamber (30). A bypass channel (31) is constructed, along which some of the flow of working fluid can freely flow from the output of a low-pressure compressor (26) to the input of a turbine stage of corresponding low pressure. In contrast to known engines, the bypass channel (31) is provided with automatically acting flaps (32) and (33) which allow passage of the flow of working fluid only in one direction - from the compressor to the turbine. This makes it possible, in operating conditions when only one high-pressure combustion chamber (29) is in operation, for the entire flow of working fluid to pass through said combustion chamber. This results in a high level of economy in said conditions.
