An idea is introduced of the directing structures of the director and reflex types that contribute to the formation of air flows, which in a given way contribute to an increase in mechanical power on the shaft of its rotor. These structures can be used to amplify the moment on the rotor shaft by increasing its useful interference with the stator. Qualitative considerations about the influence of the introduced guide structures are confirmed by the introduction and numerical aerodynamic calculations of two modernized designs of a promising vortex wind power installation, considered in the previous works of the authors. The most optimal variant of rotor modernization was selected, which made it possible to increase the power on its shaft by an average of 45% relative to the corresponding power for the design of a wind turbine with an initial rotor shape in the operating range of wind speeds from 1 to 12 m / s. The materials of this article can be used to design the optimum aerodynamic power criterion for the rotor of wind power plants, their stations, as well as integrated power power plants, including a wind power plant as one of the renewable sources of energy.

The article discusses the results of the development of the installation, which allows to ensure the process of purification of multicomponent wastewater containing organic impurities of the phenol series based on the combined method in a single apparatus, consistently combining the ozonation process with the sorption purification of oxidized wastewater, ensuring the continuity of the process and allowing the reuse of residual ozone, which greatly increases the degree of wastewater treatment and eliminates the need for the destruction of ozo on. The degree of purification achieved in this way allows the treated wastewater to be directed to the circulating water supply. The novelty of the task and the lack of available information about the combined process determined the nature and scope of experimental studies. There was a need to develop an apparatus that provides the process of purification of wastewater containing mixtures of organic compounds of the phenol series, consistently combining the process of ozonation with sorption purification of oxidized wastewater, ensuring the continuity of the process. The achieved degree of purification allows directing the treated wastewater to the circulating water supply.

The article discusses the possibilities of using forklift trucks (stacker-reach trucks) for mechanized installation of dividing walls, when cast-in-place slabs are assembled or manufactured. It is emphasized that in the early 1980s similar equipment that didn’t have a series production, was used in the construction of buildings by the lift-slab method. Some technical characteristics of the old equipment and modern warehouse equipment are compared, the advantages of the modern are revealed. It is noted that the simultaneous use of warehouse equipment on several floors of the erected frame building can lead to a significant reduction in the construction time. It is also indicated that the stacker-reach trucks used at the construction site are multifunctional, since they can not only transport construction cargo but also serve as an auxiliary equipment for safe work at a certain altitude when performing welding operations and fixing joints.

Improvement of technological process of galvanizing in flowing electrolyte without decrease in its reliability and quality of the received deposit can be carried out by carrying out anode etching of the processed surface directly in the main electrolyte of sedimentation. And, providing such conditions of anode etching at which, the details which are formed on a surface products of reactions easily are removed a channel of electrolyte is possible. For the purpose of identification of extent of influence of technology factors on anode dissolution of the processed surface it is necessary to conduct elektrokhikmichesky researches.
