The invention relates to methods for producing sulphur from hydrogen sulphide-containing gases and for purifying gases of hydrogen sulphide to produce sulphur, and can be used in the oil and gas industry, the oil refining industry and the chemical industry. Proposed is a method for producing sulphur by the catalytic direct oxidation of hydrogen sulphide with oxygen at 250-300°С in two or more stages, in which oxidation is carried out with the removal of reaction heat from the volume of the catalyst, the initial stages of oxidation are carried out at 250-300°С and a volumetric flow rate of 12000-36000 sec-1, and the final stage of oxidation is carried out at 250-280°С and a volumetric flow rate of 900-3600 sec-1, a hydrogen sulphide-containing gas being introduced into the first oxidation stage and an oxygen-containing gas being introduced into each oxidation stage, wherein at the final oxidation stage, the oxygen-containing gas is introduced in an amount that provides a stoichiometric proportion of oxygen and hydrogen sulphide. The technical result is a more broadly applicable method, increased selectivity of oxidation, reduced material requirements of the equipment and reduced energy consumption.

PCT/RU2013/001170LIVSHITS, Vladimir IosifovichLIVSHITS, Vladimir Iosifovich
The invention relates to electronic data carriers having non-volatile memory, and to a method for short-range optical communication. The aim consists in creating a simple, compact, jam-resistant data carrier and a data read/write device. In order to provide for short-range optical communication between two optoelectronic devices, a primary source of radiation is placed in a first device, and a second optoelectronic device is used in a passive mode, in which it receives power as a result of photovoltaically converting the energy of an absorbed portion of the radiation from the first device and responds to a query from the first device by means of modulating a reflected portion of the radiation. The devices are brought into contact in such a way that a light guide is formed between an active structure of the first device, i.e. an optical transceiver, and an active structure of the second device, i.e. a target, said light guide concentrating radiation in a communication channel between the devices. A reversible optoelectronic device is used as the target, said device operating as a receiver of primary radiation, and also as an electrically-controllable transmitter of secondary radiation.

PCT/RU2013/001148NONPROFIT PARTNERSHIP IN SCEINCE, EDUCATION AND INNOVATION ACTIVITIES "CENTER FOR PULSE-DETONATION COMBUSTION"FROLOV, Sergey Mihaylovich
The invention relates to pulse (pulsating) hydro-jet propulsion devices operating in a pulse detonation mode, and can be used as a power system for surface vessels and underwater vessels and for vehicles having various purposes. Proposed is a method for creating a hydro-jet thrust by means of periodically expelling outboard water from a water conduit under the influence of expanding products of the detonation of a combustible mixture, in which the outboard water, which passes into a flow-through water conduit, is sparged with gas, forming a compressible two-phase bubbly medium; when a detonation wave interacts with the bubbly medium, a shock wave enters said medium, bringing same to motion, thus leading the expulsion of the medium through an outlet section of the water conduit to be caused not only by the effect of the expanding products of the detonation of the combustible mixture, but also by the effect of the shock wave. Proposed is a device (variants), namely a pump-jet pulse detonation engine (variants), containing one or more combustion chambers, each combustion chamber having, installed therein, ignition sources, and nozzles for delivering fuel, oxidizing agent and purge gas, and, installed consecutively at the outlet of the combustion chambers, a flame accelerator, and a detonation tube having outlet apertures which are provided with a valve, wherein each detonation tube is connected to the flow-through water conduit, which is equipped with a general water intake and with aerators and/or cavitators. The proposed method for creating hydro-jet thrust and device for implementing same (variants) allow for fully utilizing the advantages of pulse-detonation combustion, and provide for minimal losses of dynamic water pressure caused by motion of the surface vessel or underwater vessel.

The invention relates to methods and devices for crushing and melting a mass of snow and ice ("snow-melters"), in which the crushing and melting of a mass of snow and ice takes place as a result of the periodic effect of shock waves and of high-speed jets of hot products of the pulse-detonation combustion of a fuel mixture, and can be used for rapidly disposing of a mass of snow and ice. Proposed are a method and a device for melting a mass of snow and ice by means of heating same through the walls of a pipe, using hot gases, and also using the hot water produced during the melting process, in which method the mass of snow and ice is simultaneously crushed and melted under the effect of shock waves and of high-speed jets of hot detonation products, wherein the shock waves and the high-speed jets of hot detonation products are generated periodically, in a pipe containing a fuel mixture, by means of a transition from combustion to detonation; in addition to crushing and melting the mass of snow and ice, the shock waves and the high-speed jets of hot detonation products impart movement to fragments of the mass of snow and ice and to the hot meltwater produced during the melting process, and also lead to the formation of water film and spray which enter the mass of snow and ice, thus leading, overall, to the melting of the mass of snow and ice without pre-treatment thereof and without the use of pre-supplied heated water. The proposed method and device make it possible to fully utilize the advantages of pulse-detonation combustion, consisting in a higher thermodynamic efficiency, a higher temperature of detonation products, the combined thermal and mechanical (shock-wave) effects on a medium to be melted, and also a reduction in the emission of environmentally harmful substances.

PCT/RU2013/001155SHIGIN, Victor VictorovichSHIGIN, Victor Victorovich
The claimed inventions relate to non-ferrous metallurgy. A melt is prepared by melting copper. The copper melt is passed into a dispensing chamber through graphite with a density of 1.56-2.2 g/cm3 in the form of a perforated element at a temperature of 1140-1175°С. The copper is refined and reduced using a carbon-containing material under an elevated temperature. A continuous cast billet is formed and drawn and is rolled by being passed at a linear speed of 1.5-2.5 m/sec through an induction heater which provides high-temperature heating to 650-800°С, after which the billet is cooled suddenly to 50-55°С. This enables the production of a copper alloy with a low oxygen content.
