Tsyrenovich V. V. — Ultrasonic impregnation of electric motor windings with insulating compounds
The "more advanced ultrasonic technological installation of Ya. Ya. Velts" is considered from the standpoint of the physics of high-power ultrasound, obliteration of capillaries, as well as the phenomenon of the formation of a cavitation region at the capillary inlet — the conditions for the occurrence of the ultrasonic capillary effect.
Keywords: ultrasonic capillary effect, cavitation region, physics of high-power ultrasound

Yangirov I. F., Sharipova R. D., Fedosov E. M., Khalikov A. R. — Modernization of the electric drive of the pumping station of the Shushnur oil collection point with a synchronous motor with a rotor starting winding in skewed slots
For the first time, the paper proposes one of the solutions to the problematic task of modernizing the electrical equipment of the pumping station of the Shushnur oil collection point by using a drive synchronous motor with a rotor starting winding in skewed slots to increase the starting torque of powerful synchronous motors and simultaneously achieve stable operation of the electric drive of the "pump-motor" system. It is proposed to make skewed slots in the pole shoe for the starting winding.
Keywords: pump, oil collection point, stability, synchronous machine, starting winding, starting torque, working winding, booster pumping station

The analysis of the current state of the machine tool building industry and its needs in the country is carried out. The works of leading authors are considered, and existing approaches to the automated synthesis of aggregate machine tool layouts are identified. General directions of development for solving the problem of automated preparation of aggregate machine tool layouts are highlighted. An original algorithm for the automated synthesis of the layout of a three-sided aggregate machine tool based on the location of the machined surfaces of the part is proposed for consideration.

Budkin Yu. V. — The contribution of scientist V. A. Kazakov to the technical standardization of mechanical engineering
The contribution of scientist Valentin Alekseevich Kazakov to the development of methods of technical standardization in mechanical engineering is investigated, which resulted in the formation of the section "Product Quality Management. Standardization. Organization of Production" in the journals of the publishing house "Tekhnologiya Mashinostroeniya."
The organizational ability to unite scientists, engineers, and technologists for the development of technical standardization in mechanical engineering is revealed. It is shown that the results of publications became the basis for the development of modern enterprise standards (technical specifications) of the machine-building complex for the implementation of scientific and technical solutions, as well as for inclusion in the Federal Information Fund of Standards.
