Abstract: We examined the basic control of water quality. Were studied design features in the system generation of purified water. Identified the most suitable plate heat exchanger, it is considered the principle of action and benefits.

Keywords: purified water, a plate heat exchanger, Pharmacopeia, Good Manufacturing Practice, GMP.

Summary: The computational model of additional errors, which occur from interaction of intense shock N-wave with inertial positioning devices of hypersonic aircraft was built. Angles of coincidence for the industrial design of the angular velocity sensor were fitted. A comparative analysis of the experimental data for seminatural conditions for the two cases (gyroscope ON, gyroscope OFF) was made. Conclusions about the possibility of use of the results were made.

Key words: N-wave, hypersonic aircraft, caustic zone, wave coincidence, float gyroscope.

Summary: In the paper modern playpens constructions, which is designed to create a specific skills or abilities in childhood, are analyzed. Established presence and degree of influence of Coriolis acceleration on the formation sided driving ability of upper and lower extremities during the development of children. The construction of playpen, which provides a full and harmonious development of the child, is purposed.

Keywords: playpen, Coriolis acceleration, left-handed, right-hand limbs, Coriolis force of inertia.
