Current pulse generated at the lightning strike is transformed by Tesla transformer. A series-oscillatory circuit is included into the device composition. |

Invention relates to electrical engineering and particularly to electric heating of gases with an arc discharge, and can be used in plasmatrons when conducting various processes, particularly for heating molten metal in an intermediate ladle of a continuous-casting machine in the metallurgical industry, as well as scientific research of high-temperature processes. In an electric-arc plasmatron, having water-cooled cylindrical inner and coaxial outer electrodes, as well as a swirler in the annular channel in between, an arched cylindrical chamber is placed at the end of the inner electrode. The outer electrode is in the form of a cup with an expanding outlet channel at its bottom, which is connected to the cavity of the cylindrical chamber of the inner electrode through a radial gap between the end surfaces of the electrodes. The diameter of the entry section of the expanding outlet channel of the outer electrode is less than the diameter of the cylindrical chamber of the inner electrode. |

Control method of independent asynchronous motor In control method of independent asynchronous generator with a valve inverter in a rotor circuit, rotor voltage frequency is proportional to a sum of rotor rotation frequencies and a generator stator field, signals for setting of instantaneous values of sine three-phase voltages of a rotor winding, which are offset relative to each other through an angle of 2π/3 are shaped, deviation between the specified and the measured signals of phase voltages is determined, deviation is compared to a threshold level, at the exceedance of which control signals are supplied to control inputs of the corresponding phase of the valve inverter, key elements of the valve inverter are switched, thus reducing deviations between the specified and the measured signals of phase voltages at the output of the valve inverter to the value that is lower than the threshold level. |

Invention relates to improved method of obtaining workpieces from silver halides and their solid solutions for fibrous infrared lightguides, which includes application on silver halide crystal-core of crystalline shell of crystalline silver halide with refraction index lower than in crystal-core, and thermal processing. Shell on crystal-core is applied by ion-exchange diffusion in ion-exchange source, as the latter taken is finely disperse silver halide powder with coarseness 1-20 mcm, diffusion is carried out at temperature, close to melting temperature of crystal-core in atmosphere of mixture of vapours of halides, included into composition of crystal material and powder, taken in equal ratio under pressure 0.2-0.5 atm. |

Method, system, relay station and base station for transmitting data in mobile communication Invention relates to wireless communication engineering and can be used to transmit data. The method of transmitting data in mobile communication and for application in a cell having a base station and more than one relay station, includes switching, by at least one of the relay stations under the control of said base station, between at least two operating modes when transmitting downlink signalling, wherein said at least two operating modes include a mode for non-participation in transmitting downlink signalling and an operating mode for transmitting downlink signalling jointly with the base station. If said relay station is in operating mode for transmitting downlink signalling jointly with the base station, then said relay station receives downlink signalling transmitted by the base station before the transmission time; and during transmission, the relay station and the base station transmit said downlink signalling to user stations/mobile stations simultaneously. |
