In the upper part of the shaper 1 three outlet branch pipes of channel aerosol flows are located, each of which is connected to the mixer 2 of channel aero disperse flows, connected with the pair of dynamic subchannels 3. Each of dynamic subchannels 3 contains seating cases for laboratory animals. Inside the shaper 1 of aerosol flows the air flow divider is coaxially placed. Through the divider centre the axis of the air fan with blades located in the horizontal plane in the lower part of the flow divider vertically passes. |

Screw propeller assembly containing one hub and at least two blades Invention relates to a mixing assembly for generation and support of movement in waste water containing more or less non-filtered contaminated liquid containing solid material such as plastic material, hygienic items, fabrics, waste cloth, sand, etc., which includes a hub and at least two blades (4) that are connected in a detachable way to the above hub, with that, the rear end of the hub fits for connection to a drive shaft and therefore for being brought into rotation about an axially continued central axis. According to the invention, the hub includes socket (9) for each of at least two above said blades (4), with that, each socket (9) includes the first engagement device (10) that is axially continued, and each blade (4) includes the second engagement device (11) that is axially continued, with that, both of the above said first engagement device (10) and the above said second engagement device (11) fit for axial mutual movement of the above hub and each of the above blades (4) during attachment/removal of the screw propeller assembly, and besides, they fit for prevention of radial mutual movement of the above hub and each of the above blades (4) when the mixing assembly is in an assembled state. |

Invention relates to guide adapter for fluid-impermeable joint between mixer and septic tank cover which includes first element (12) that makes central bore and central axis extending axially and second element (13) that makes central bore and central axis extending axially. Note here that second element (13) central axis length can be adjusted relative to that of first element (12). In compliance with this invention, said guide adapter comprises the device to create contact area for fluid arranged at interface between said first and second elements (12, 13). At least three positioning devices serve to set relative axial positions of said first and second elements (12, 13). Note here that at least two of said positioning devices are composed of independent regulators (24) arranged relative to said tank at opposite side of said device to create contact area impermeable for fluid. |

Method for ultrasonic cavitational processing of liquid media and objects located in medium Method includes placing liquid media and objects located in a medium inside a mechanical oscillatory channel system, having a nonlinear relationship between resonant oscillation frequency and amplitude, wherein the method includes maximum alignment of resonance curves of an ultrasonic vibration generator and the nonlinear resonance curve of the channel system itself by determining the nonlinear resonance curve of the channel system as the relationship between the amplitude of mechanical vibrations and frequency, determining the difference between the frequency of the generator and the resonant frequency of the channel system at the required amplitude of vibrations and, based on said difference, changing the resonant frequency of the channel system by changing the geometric dimensions of the sizes. If the difference in frequency exceeds about 1.5-2.0 times the width of the resonance curve of the generator, vibrations are generated at two or more different frequencies. |

Method of processing of water flow downstream of fischer-tropsch reactor Invention relates to water treatment. Treatment of water flow fed from Fischer-Tropsch reactor comprises the fed of water flow portion to aerator, to distiller and /or evaporator and therefrom to said aerator again. Note here that process gas is fed to said aerator to produce gaseous flow to be fed to the plant for production of synthesis gas. |
