The vertical-axis wind turbine comprises a shaft (2) rotating around longitudinal axis and multiple hard turbine blades (7) combined into one or more turbine units (1). The one turbine unit (1) is made of one bottom (6) and one top (6) tube rings. The other turbine unit (10) consists of two bottom tube rings (13 and 14) concentrically positioned one above the other and two top tube rings (6 and 1 1) concentrically positioned one above the other. The tube rings (6, 11, 13 and 14) are fixed perpendicularly to the single shaft (2) by means of distribution washers (4) and load-bearing radial ribs (3). In addition to the load-bearing radial ribs (3), the concentric pairs of tube rings (6, 11, 13 and 14) are joined together also with supporting ribs (12). Each turbine blade (7) is attached with its one end to a load-bearing radial rib (3) or to a supporting rib (12) of the top pair of tube rings (6 and 11) and with its other end to the subsequent rib of the bottom pair of tube rings ( 13 and 14).

The invention relates to a method and device for production of plasma and finds its application in heat engineering, for destruction of any kind of waste, for gasification of carbon- containing solid and liquid materials, for melting and soldering of metal and non-metal materials. In this method for plasma production, water is supplied under pressure from a water tank (1) by a water pump (8) to a distributor (2), wherefrom the water is divided into two water streams, both of which pass through flexible pipe connections (3) and each one separately goes into a pair of pipes with one of their ends open (5), with each of the pipes accommodating one electrode (4), where under the influence of high voltage direct current applied in the clearance between the two flowing-out water streams plasma (6) is produced with temperature exceeding 4000 °C, while the unused part of the water, flowing freely throughout the open ends of the pipes (5) via the funnel-like collector goes back to the water tank (1). The plasma producing device comprises at least one pair of pipes (5), made of heat- resistant insulation material, in which water is supplied from a water tank (1), by a water pump (8) installed on it, feeding pressurized water to distributor (2), and by means of flexible pipe connections (3) the water is supplied to the pipes (5), inside which at least one pair of electrodes (4) are installed, each pipe accommodating one of them, connected to the opposite poles of high voltage direct current (7) source.

The extreme optical shooting simulator is used for team military games and sport competitions and as a tactical training device. It consists of a simulation 'gun' and a personal target. Two emitters are mounted on the simulation 'gun': a narrow-beam emitter (1) in which a laser or non-laser light-emitting diode is installed as a source; and a wide-beam emitter (2) having a non-laser light-emitting diode installed therein. When a signal is received from the low-divergence emitter (1), a precise hit on the personal target is simulated by means of 'ammunition' mounted thereon for an acoustic pyro effect with smoke (3). If a signal is received from the high-divergence emitter (2), devices (4) for the acoustic simulation of flying bullets, a light-emitting diode display and mechanical vibration are activated. The purpose of the invention is to add an extreme hit effect and the effect of bullets flying past the player to optical 'laser tag'-type shooting simulators.

The invention relates to a device and an instrument for the cold expansion of mounting holes. The advantages of the device and the instrument consist of being able to control the degree of cold expansion. The device (61) comprises a hydraulic cylinder (27) which houses a piston (26) with a piston rod (25) that has a mandrel (1) of the instrument (60) attached to the end thereof. A threaded bushing (7) of the instrument (60) is rigidly fixed to a flange (9), and a linear displacement sensor (34) is installed in an axial blind hole (55) in the piston rod (25) and is rigidly fixed to the hydraulic cylinder (27). A magnet (33) is provided to actuate the linear displacement sensor (34), which is connected to a command-control unit (38).

The set of components for the assembly of pipeless insulating and heating solar panels is intended, as the name suggests, for the assembly of such panels. The panels are designed for direct mounting onto walls or other surfaces. Using individual components from the set and other readily accessible materials, it is possible to make solar panels of any size and having any chosen shape, insulation thickness, pipe connection points and fastening points for attachment to surfaces. In other words, it is possible to produce solar panels and an insulating cover all-in-one to suit the criteria of each individual location. Such panels make it possible to cover the facades and/or roofs of various buildings irrespective of the location of windows, doors, pipes, etc. With the aid of such panels, surfaces can be completely covered with an insulating layer while the entire surface will be capable of absorbing energy from the sun.

The pipeless heating and insulating solar panel is designed for direct mounting onto walls or roofs. The panel forms an insulating cover on the surface on which it is mounted. Thus, two aims are achieved using a single article and a single building operation. As a result, an outside surface is provided with an insulating cover while at the same time being able to actively absorb energy from the sun. A further defining characteristic of this solar panel is that when the heat-transfer agent is heated, it flows inside the panel directly underneath a transparent covering and travels across the whole of the face of the solar panel.

The method and device find application for obtaining of staple fibre yarn in a single process of combing, drawing, and twisting. In the method, the fed fibrous sliver of staple filaments (1) is subjected to combing of, first (β) their front ends, and of, next (γ), their rear ends, with continuous high rate drawing The device consists of a feeding roller and a feeding table, the feeding table (9) and two main arc-like surfaces (β) and (γ) covering part of the surface of the combing needle roller 1 1, which is perforated and finishes close to a drawing trine of rollers (21, 22 and 23).

A zero flow responsive heart stimulator contains a zero flow sensors, which generate signals at the moment of the termination of blood inflow in the right atrium and the right ventricle, sensing this the most precisely in the places, where the sinoatrial node and atrioventricular node reside, for the right atrium and the right ventricle, respectively. The stimulator is based on our discovery, that the two nodes are the same sensors in the biological systems, based on the fact that until the filling of the said two chambers continues, the venous blood flow sucks on Bernoulli's principle the Ca and Na cations from the two nodes interstices, preventing the inward currant in their cells, thus delaying the completion of the 0-phase of their depolarization and the action potential, until the blood flow stops. Our discovery proves that the alternating flow/no flow of the blood in the orifice of superior vena cava and the entrance of the right ventricle is the real pacemaker that fires the both nodes, but not the inverse, as generally assumed, approximating the natural pacemaker to a clock mechanism. This, together with the discovered by us arteriovenous, arteriolymphatic and capillary pumps, closes the loop of the autonomous automatic functioning of the cardiovascular system, even completely denervated and in the absence of muscle contractions. It is the first devise, which activates the atrial and the ventricular contractions in a function of the zero-flow of the filling them venous blood, which is the exact imitation of the sinoatrial and atrioventricular firing.
