Storage of liquefied natural gas To exclude heat inflows to LNG and to increase timing of its non-drainage storage a reservoir 3 is made from reinforced concrete and installed in a container 1 on supports 2, made of materials with low heat conductivity. A gap 4 between the reservoir 3 and the inner walls of the container 1 is filled by a loose heat insulating material. For assembly of the inner reservoir 3 the external container 1 has a detachable roof 5. To add the loose heat insulating material in the roof 5 there are closed process holes 6. To fill and drain the inner reservoir 3 with liquefied natural gas there is a system of filling and draining 7 with pipelines and stop and control valves. |

Operation of exhaust gas purification device Invention relates to ICE exhaust gas purification device operation. The essence of the invention: operation method of device 1 for the purification of exhaust gas including a heater 3 and a reducing agent feeder 4. This process comprises, first, checking if the reducing agent is to be fed and, then, various patterns of heating are realised. In case the reducing agent should be fed, the exhaust gas purification device is heated by the heater 3 unless the first limiting temperature 8 is reached in case the first main temperature 7 is lower than the said temperature 8. In case the reducing agent should not be fed, the exhaust gas purification device is heated by the heater 3 unless the second limiting temperature 10 is reached in case the definite second main temperature 9 is lower than the said temperature 10. |

Invention relates to automotive industry. A valve of a tyre 1 comprises a channel valve 11 with a valve seat 15, a valve body 10 provided with at least one connection element 9 for the connection of the valve body 10 to its base 2. The valve body 10 comprises a slide 12 arranged in the valve channel 11 to displace axially therein. The said slide at the closed valve 11 tightly abuts on the valve seat 15 of the valve body 10. Note here that the valve body connection element 9 is spaced from the valve body working section in the axial direction of the said section 8. The valve body 10 is a single-piece element. The valve slide 12 is retained by a spring 19 pressed to the valve seat 15. To open the tyre valve 1, the slide 12 should be displaced at overcoming the spring force. |

Device for sampling of outer surface of space object by astronaut Invention relates mostly to tools used by an astronaut in open space. The device comprises a body from a chemically, thermally, mechanically stable and γ-permeable material. In the body there is one or more dead threaded cavities with a conical surface at the inlet. A sampler with a responsive conical surface providing for sealing of the cavity during contact of both conical surfaces is screwed into the cavity. A metal plate is fixed to the body, the cut in which produces a handle to grip the body by an inflated glove of the astronaut's spacesuit. On the Earth the device in the assembled and sealed form is sterilised by γ-radiation. On the orbit the cosmonaut holding the body by the handle extracts the sampler from the cavity. After sampling and sealing of the sampler the device is returned to the Earth for analysis. |

Automotive diesel dual fuel feed system Invention can be used in internal combustion engines. A dual-fuel automotive diesel feed system comprises a mineral fuel tank 1, a vegetable fuel tank 2, a fuel coarse filter 3, a fuel fine filter 4, a fuel feed pump 5, fuel lines 6 and 10, a high-pressure pump 8 and atomisers 9. The mineral fuel tank 1 is connected via the fuel line 10 to the channel 11 and mixer 7 arranged at the vegetable fuel tank bottom. Note here that the mineral fuel tank 1 is arranged higher than the vegetable fuel tank 2 to flow the mineral fuel by gravity into the said mixer. |
