Tubular electric heater contains a heat-producing element 1, for example in a form of a current-conducting spiral placed inside a protective metal shell 2 with an external circumferential finning 3, at the ends of the metal shell 2 there are sealed current leads 4 connected to the outputs of the current-conducting spiral, porous ceramic beads 5 of a tear-drop shape with the heat-producing element 1 placed in their internal opening, along their perimeter the beads are covered by the protective metal shell 2, the porous ceramic beads have width variable by height thus covering the heat-producing element completely or covering it minimally in the upper part, the inner cavity of the tubular electric heater, including pores of the ceramic beads, is filled with liquid partially. When voltage is supplied to the current leads 4 connected to the outputs of the current-conducting spiral the temperature of the spiral is increased as far as heat conductivity of the porous ceramic beads 5 is low, heating of the spiral of the heat-producing element 1 takes place fast, nevertheless the temperature of the protective shell 2 and finning 3 is defined by the temperature of the external heat carrier. As far as the inner cavity of the heater and pores of the beads are filled with liquid at certain temperature this liquid boils, steal comes through the pores to the space between the porous beads 5, where it is condensed at the inner surface of the protective shell 2 giving it the accumulated evaporation heat. The condensed steam in the form of liquid comes to the surface of the porous beads 5 and due to capillary action it is saturated inside into the beads 5 coming down to the heated spiral, there it boils again thus accumulating evaporation heat and closing the cycle of heat transfer and circulation loop. |

Pressure pump with dielectric barrier and method of its fabrication Invention relates to pressure pumps. Pressure pump with dielectric barrier for acceleration of fluid flow comprises first dielectric layer with first electrode built therein and second dielectric layer with second built-in electrode. Said first and second dielectric layers are spaced apart to make an air gal there between. Third electrode is arranged at least partially in said air gap relative to fluid flow. High-pressure signal is fed to third electrode from HV source. Said electrodes interact to generate opposed asymmetric plasma fields in said air gap to induce airflow in said gap. Induced airflow accelerates fluid flow in its travel via said air gap. |

Methods and apparatus for encoding information on ac line voltage Invention relates to electrical engineering, particularly systems for controlling lamps by encoding an AC power signal. AC line voltage may be encoded with control information, such as dimming information derived from an output signal of a conventional dimmer, so as to provide an encoded AC power signal. One or more lighting units, including LED-based lighting units, may be both provided with operating power and controlled (e.g., dimmed) based on the encoded power signal. In one implementation, information may be encoded on the AC line voltage by inverting some half cycles of the AC line voltage to generate an encoded AC power signal, with the ratio of positive half-cycles to negative half-cycles representing the encoded information. In other aspects, the encoded information may relate to one or more parameters of the light generated by the LED-based lighting unit(s) (e.g., intensity, colour, colour temperature, etc.). |

Lighting system and light processing method Invention relates to lighting engineering. Disclosed is a lighting system, having a plurality of light sources equipped with encoding devices so that light emitted by the light sources contains identification codes of the light sources. To generate a light effect, i.e. to correlate light sources with their light spots, the system further includes a camera designed to take images of light spots and a signal processor designed to extract identification codes of light sources from the obtained images. The encoding device are used to modulate emitted light with a frequency higher than a given high level, so that light contains "fast" codes, and a frequency lower than a given low level so that light contains "slow" codes. |

Method for modification of ionospheric plasma Method for modification of ionospheric plasma includes formation of artificial plasma accumulation in result of blast waves propagating from places of explosive cartridges blasting. Pyrotechnic release is made from the cartridge in radial directions, shaping of propagating blast waves is made by simultaneous explosion of all explosive cartridges, at that plasma accumulation with pulsed electromagnetic fields in it is formed in the central area of influence due to converging blast wave formed as a result of the fronts joining of some explosions. |
