Abstract: FIELD: medicine; methods for enhancing biological activity of medicinal and edible fluids. SUBSTANCE: method is carried out in apparatus comprising alternating-current source 1 generating electric current at frequency f and connected via current-adjusting element 2 with solenoid 3 accommodating vessel 4 filled with fluid to be magnetized. Command signals for generating unlike-polarity pulses are issued by control unit 5 and arrive at adjusting element 2. Proposed method resides in following: fluid- filled vessel 4 is placed into solenoid 3, apparatus 1 is turned on, and current-adjusting element 2 generates unlike-polarity current pulses which, in turn, generate corresponding unlike-polarity pulses of magnetic field intensity, field amplitude increasing from zero up to Hm value during N periods. Magnetic field thus-tuned is maintained in fixed reached mode during M periods, followed by progressively attenuating amplitude down to its zero value during P periods of alternating magnetic field at frequency f, values of peak magnetic field intensity Hm, time N/f of alternating magnetic field rise, time during which field is held at its peak value M/f, and time P/f during which magnetic field declines to zero being selected individually for each edible or medicinal fluid. With this approach, fluid is exposed to effect of alternating magnetic field by varying its amplitude and fluid exposure time. EFFECT: higher efficiency. 2 dwg

Abstract: FIELD: pneumatics. SUBSTANCE: guides of a link are arranged asymmetrically with respect to the axis of rotation of the link. As a result the angle between guides and axis of the screw in the end position decreases. Free strokes allow a rotor jet engine to be started easily and additional starting torque to be applied to an object to be controlled owing to kinetic energy accumulated before the free strokes. Smooth contour of the arms of the rotor and deflection of the jet at sloped exits of the nozzles decrease drag. The spring-loaded support provides absorption of kinetic energy that is accumulated by rotating parts to increase the starting torque in the opposite direction. EFFECT: improved design.
