Description
The model of identification of process of a dust con-tent of the air is submitted. It is shown, that in a work-ing zone of foundry shops the significant amount of a dust is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The dust is most dangerous to health of the working personnel and creates problems at clearing air. The model of structure of dusty air is received

IMPROVING THE EFFICIENCY OF WEAR-RESISTANT COATINGS ON CUTTING BLADES UNIVERSAL GRINDERS
DescriptionIn the article, it is established that in the market conditions of economic recession of repair production, the traditional technological decisions focused on mass and business lot type, have lost the practical importance. Increase of the efficiency of drawing of wearproof coverings with the electropulse way is based on the use of technological possibilities of the way and the principles of technical self-sufficiency of small repair shops. For that, the combined way of processing, replacing use of the traditional technological equipment, with obtaining quality comparable to the existing technologies has been developed

RAISING EFFICIENCY OF PROTEINS ISO-LATION FROM RECYCLED DAIRY RAW MATERIALS
DescriptionInvestigation results of dairy proteins coprecipitation from skim milk and curd cheese whey are demonstrated. For different ratio of the components in the milk-whey mixture, the authors determined the parameters providing maximal effi-ciency of precipitation and outlined the factors stipu-lating intensity of separation and properties of pro-tein-chitosan complex. Efficiency of whey protein isolation and interaction of chitosan with protein in stable complex are explored
