Abstract: FIELD: electric engineering, applicable in various branches of industry, agriculture and housing. 
     SUBSTANCE: the method consists in the fact that a three-phase voltage is applied via three pairs of antiparallel connected thyristors to the stator windings of the asynchronous motor, and the control signals from the pulse-phase control system synchronized in the mains voltage are supplied to the control inputs of the thyristors, a signal in the form of voltage equivalent to the opening angle of the thyristor, whose value is preset in advance in each moment of time, is applied to the mains input. The instantaneous and acting values of the mains voltage and current in the stator windings of the asynchronous motor are measured, and at a deviation of them from the preset values the supply of the control signals to the thyristors is stopped. The additionally measured acting values of current in each period of the mains are estimated as the maximum, and as soon as the maximum is attained, it is memorized and the acting value of current of one of the phases is measured anew in each period of the mains, it is compared with the maximum value. At a deviation from the maximum value by the preset value a signal is formed for full opening of the thyristors and maintained for the period of operation of the asynchronous motor in the rated conditions. 
     EFFECT: eliminated oscillations of the phase currents, electromagnetic moment and rotation speed of the rotor in the thyristor converter - asynchronous motor system operating as part of the electric drive with a pump or ventilation load.

Title: Method of measuring concentration of surface-active substance
Inventor: BEZUGLYJ B A
IPC: G01N13/02
Filed: 2003-12-04
Granted: 2005-03-10
Abstract: FIELD: measuring engineering. 
     SUBSTANCE: method comprises generating thermocapillary convection by laser beam in a layer of fluid on the substrate which absorb laser radiation. After the light beam is turned on, the substrate begins to liberate heat, and heat front propagates from the substrate to the free surface of fluid through the layer. Once the front attains the free surface, the heat front induces the capillary flow which results in the dynamical deformation of the free surface of the layer providing a hollow. The higher concentration of the surface-active substance, the higher temperature is required for generating thermocapillary flow and, the longer time lag required for free surface to be deformed. The deformation is indicated on the screen as the deviation of the diameter of the beam spot from its value corresponding to the reflection from the flat free surface or as change in the distribution of the spot intensity. The concentration of the surface-active substance can be judged by the time interval between the moment of the turning on of the laser beam and the moment of the onset of variations of the diameter or distribution of the spot intensity on the screen. An experimental dependence of the time interval on the individual surface-active substance concentration should be obtained. The dependence is used then as a calibration one for the measurement of concentration of this surface-active substance. 
     EFFECT: simplified method and reduced time consumption for measurements.
