Sodium chlorate is an important product for the Ukrainian and global economy. Based on the study of the stages of electrolysis of an aqueous solution of sodium chloride and the separation of chloride-chlorate solutions by evaporation-crystallization, a design of a periodical action installation for the production of crystalline sodium chlorate was developed. The research results showed that it is possible to avoid the stage of hot filtration of the suspension after evaporation and, in general, to simplify the technology and reduce its energy consumption.

The article presents the results of theoretical and experimental developments regarding the marking of scans and patterns of fittings of the ventilation system, provided that the unification of installation and procurement work.

If you analyze the city’s architecture at the turn of the 19th and 20th centuries, you will be surprised by how many public and residential buildings were constructed, and often designed, by Levynsky company. Levynsky was a respected philanthropist, an active member of cultural and technical societies, among others, of the Polytechnic School Society, the Society of Workers and Industrialists, and a participant in Ukrainian social life–for instance, an activist for the Prosvita Society.
