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. The installation including electric was for this purpose developed and made and gidravklichesky speak rapidly. The Elektkrichesky part contains power-supply circuits of an electrolytic cell to the asymmetric variables odnopoluperiodno straightened, dvukhkpoluperiodno straightened by current and straightened by current with the lowered pulsation, and also a chain of heating of working electrolyte. The hydraulic scheme of experimental installation includes: the kisloktostoyky electric pump, pipelines, filters, the device for an electrolytic precipitation of coverings and a bathtub with electrolyte. Electrolyte in a cell moved by means of the electric pump. Giving changed in steps, due to change of diameter of the section through passage of the giving pipeline by means of replaceable inserts. Authors of the device for electrolytic drawing coverings are Zakharov Yu.A. and Spitsyn I.A. (patent No. 2155827). The design allows: to increase the speed of a channel of electrolyte; to carry out activation of the cathode, using energy of a channel of electrolyte; to increase the accuracy of copying of the cathode the activating elements; to use higher density of current and to reduce power consumption of the device. Electrolyte, in the course of sedimentation, was constantly filtered. As filtering material used fiber glass. The filter if necessary it is possible to dismantle and wash out quickly. Such filtering element slightly interferes with a channel of electrolyte, is simple in service, is cheap and quite sufficient. Thus, the offered design of experimental installation allows to conduct necessary researches of process of sedimentation of a zinc electrodeposit for its improvement.

This article examines some aspects of hypothetical interaction between Artificial Intelligence (AI) device and a man in which the goal of AI is self-learning to think. The practical reason of this task is to draw attention to a number of significant features of thinking that are important for AI engineering. The main issues of AI methodology and its critics are analyzed. It discusses the features of a person's thinking, which will inevitably face the AI​​, even though they have marks of formalizing impossibility as well as positive heuristic properties and functionally irremovable out of thinking. Analogy, complexes and pseudo-concept, contradiction are considered among these features. It's shown that communication is a source of new information imparted to the system essential for thinking and ensuring its development.

Considered clean water in swimming pools, on nonionic and anionic surfactants with special adsorbents. Water purification pools plavatelnyx unique, first of all, because the water contains various types of pollution, which it is exposed. Most of these contaminants are introduced by the users of the swimming pool and they have to be removed or destroyed (bacteria, viruses, organic, sweat, hair, makeup, etc.). Treatment of swimming pool water is much more complicated because of the need to carry out her many times, than drinking water treatment, which is carried out one-time. Based on these studies, given technological solution to improve the efficiency of purification of circulating water in swimming pools, ensuring high environmental and economic performance of water treatment.

Nowadays, the main way to improve power density is increasing the junction temperature of semiconductor devices and as a result, increasing the temperature of the heat sink. This results in a lower efficiency due to the high temperature caused by increasing power losses. To solve this problem, it’s possible to develop the heat sink for a specific system, or to optimize existing heat sink profiles. This paper presents an FEM-analysis describing thermal behavior of a bidirectional switch used in a direct matrix converter.
