Description
In this article we have investigated fatty acid composition of oil made of flex seeds of VNIIMK-630 traditional variety and new selected SURPRISE variety. The comparative analysis of composition and factional composition of tocopherol in oil made of these seed varieties has been carried out. We studied changes in acid and peroxidation numbers when flex seeds are stored in the dry condition

DEFINITION OF ELECTROMAGNETIC ENERGY AND MOMENT IN THE CASCADE ELECTRIC DRIVE
Description
The problem of calculation of arguments of the controlled cascade electric drive is reviewed. For a basis the electric drive is taken by the designed writers. For definition of the moments the method grounded on electromechanical transforming of energy is proposed. On an example of a present construction the values of currents of a stator and rotor and phase angles of these currents were retrieved. It has allowed to find the energy, accumulated by the device, in the given instant. Utilizing this result, the instantaneous moment was defined. The introduced mathematical model realized as the program in environment Delphi. Inaccuracy for an audit example did not exceed 10-15 %

EXPERIMENTAL RESEARCHES OF THE AEROHYDRAULIC WATER LIFT
Description
In the article, we have presented the experimental researches of the aerohydraulic water lift. The influence of the pressure on the aerohydraulic water lift and water giving height on productivity has been researched as well as we have made a multifactorial research of productivity of aerohydraulic water lift. It has been established that productivity of the aerohydraulic water lift depends on the difference between pressure and water giving height. Influences of diameters of submitting and nutritious pipelines on productivity have been established
