Title: Multifunction stator winding of induction generator
Inventor: BOGATYREV N I
IPC: H02K17/14
Filed: 2003-09-01
Granted: 2005-03-27
Abstract: FIELD: electromechanical engineering. 
     
     
       SUBSTANCE: proposed stator winding has six concentrically disposed pairs of different-pitch coil groups with single-layer coils of external groups and double-layer ones of internal groups. Coil groups of pairs 1 and 4 are included in first phase, those of pairs 3 and 6, in second phase, and coil groups of pairs 5 and 2, in third phase. Different-pitch coil groups of different pairs are differentially connected in each phase. First phase leads are taken from finishing leads of external coil groups of pairs 1, 3, 5. Second phase leads are formed by integrated starting leads of external coil groups and from finishing leads of internal coil groups of pairs 4, 6, 2. Connected to starting leads of internal coil groups of pairs 1,3, 5 is additional eight-pole low-voltage winding; field capacitors and main load are connected to first and second phase leads. Such design of stator winding makes it possible to build off-line power supplies for different current frequencies at different voltages around capacitor-excited induction generators with drive motor rotating at fixed speed. 
     
     
       EFFECT: enlarged functional capabilities of winding.

Abstract: FIELD: purification of the steam-gaseous medium discharged into the atmosphere from hydrocarbons. 
     SUBSTANCE: the invention is pertinent to the field offluidics and intended for use in the systems of purification of the steam-gaseous medium discharged into the atmosphere from hydrocarbons formed during storage of petroleum and at filling up containers with oil products. The method includes pumping a liquid medium in the liquid-gaseous jet device, the steam-gaseous medium pumping out by the jet device from the container filled with petroleum and-or from a reservoir used foe storage of petroleum, the steam-gaseous medium squeezing in the liquid-gaseous jet device at the expense of power of the liquid medium, feeding of the mixture of steam-gaseous and fluid mediums formed in the liquid-gaseous jet device into a separator, separation in the separator of the mixture for a gas phase and a liquid medium with withdrawal from the separator of the gas phase and the liquid medium. A gas phase from the separator is fed into an absorption tower, into which in the capacity of an absorbent a hydrocarbon liquid is fed. In the absorption tower they carry out a process of absorption by the hydrocarbon liquid of hydrocarbon from the gaseous phase. Then the purified from hydrocarbons gaseous phase and the hydrocarbon liquid with dissolved in it hydrocarbons of the gaseous phase are separately withdrawn from the absorption tower. In the capacity of a hydrocarbon liquid they use gasoline or kerosene fractions of a crude distillation and before feeding the hydrocarbon liquid into the absorption tower is cooled to the temperature located in the range from minus 10°C to minus 50°C. At that the gaseous phase after its withdrawal from the absorption tower is fed into a membranous apparatus, where the rest gaseous hydrocarbons are separated from it. Then the depleted hydrocarbon gas and the enriched with hydrocarbon gas are separately withdrawn from the membranous apparatus. The invention ensures reduction of losses of the oil products and an increased efficiency of purification from hydrocarbons of the steam-gaseous medium formed during storage of oil products and at filling containers with them. 
     EFFECT: the invention ensures reduction of losses of the oil products, increased efficiency of purification.

Abstract: FIELD: medicine; ophthalmology. 
     SUBSTANCE: multi-focal intraocular lens can be used for correction of vision and for production of multi-focal intraocular lens. Lens has two refracting surfaces; at least one lens has diffraction structure in form of microscopic relief on its surface. Diffraction structure is made in such way that central diffraction area and concentric diffraction areas are formed onto it; areas are disposed around mentioned central area. On the way of mentioned diffraction areas from center of lens to its peripheral part, square of any sequent diffraction area is (1+M) times bigger than area of previous diffraction area, where M is factor of area increment; value of factor equals at least to cλ/f, where c is dimensionless aberration coefficient, λ is structure wavelength, f is focal length of diffraction structure. Method of manufacture of multi-focal intraocular lens is based upon production of pair of matrices, which matrices when being disposed in opposition to each other, form cavity which follows preset shape of lens. Then the cavity is filled with liquid transparent matter of lens, followed by hardening. For manufacture of matrix, forming microscopic relief of diffraction structure, liquid photoresist material is applied onto hard surface of substrate to form film. Photoresist material film is subject to drying until it reaches solid condition. Then surface of photoresist film is subject to effect of pulse laser radiation while shifting laser beam along surface of mentioned film along circular or spiral trajectory by changing frequency of laser radiation pulses in proportion with distance of position of laser beam from center of diffraction areas formed. Then film is developed to get microscopic relief onto its surface. After that the microscopic relief or its mirror reflection is transported onto internal surface of mentioned matrix. 
     EFFECT: precise representation of microscopic relief of diffraction structure without side marks or any traces of mechanical treatment; higher correction of asymmetric aberration.
