Water-alcohol vapour from upper plate of lower zone of its concentrated part is partially condensed in first epuration column dephlagmator. Partial condensation of vapour from still-head pipe of said column is carried out in first section of second dephlagmator, formed phlegm is returned to upper plate of said column. Enriched with ethyl alcohol and admixtures non-condensed vapour is diluted with purified water vapour and supplied into second section of second dephlagmator, where main and intermediate admixtures are concentrated and removed from wash-rectification system.

Yeasts of genus yarrowia, having ability to accumulate intracellularly fatty acid esters, and method of microbiological synthesis of such esters

Invention provides a method of production of fatty acid esters using yeasts belonging to the genus Yarrowia, having the ability to accumulate intracellularly fatty acid esters under conditions of limit in nitrogen or phosphorus, when alcohol is added to the culture medium in addition to the main carbon source, characterised by the absence of activity or decreased activity of the enzyme glycerol-3-phosphate dehydrogenase, and expression of the gene encoding the enzyme-nonspecific CoA-dependent acyl transferase. The invention also relates to the yeast strain Yarrowia lipolytica of RNCIM Y-4042, capable to accumulate intracellularly fatty acid esters.

Method for seismic monitoring when developing hydrocarbon deposits at water areas

Method comprises performing three-dimensional seismic survey and using data thereof to construct a model of the reservoir; predicting the orientation of systems of subvertical cracks and placing producer and injection wells; placing fixed seismic cables at the bottom of the water area over the deposit; detecting seismic traces with elastic vibrations from artificial sources and controlling the process of developing the hydrocarbon deposit based on dynamic and kinematic changes in the detected vibrations when processing the seismic trace. The seismic cables are placed at the bottom of the water area before drilling producer wells. When drilling producer wells, microseismic vibrations excited by the drill bit at the well bottom are detected, during processing of which, based on dynamic and kinematic characteristics, anisotropic properties of the medium in the drilling area are determined, the orientation of the systems of subvertical cracks is refined and the three-dimensional models of the reservoir, the arrangement and drilling path of producer wells, perforation areas and hydraulic fracturing are corrected.

Phase-interference module

Phase-interference module

Invention relates to microscopy and can be used in biology, medicine and optical instrument-making. The phase-interference module comprises a microscope for forming an enlarged image of a microscopic object in the back focal plane of said microscope, a 4f optical system consisting of two Fourier lenses, the front focal plane of which coincides with the back focal plane of the microscope. An output image recorder is placed in the back focal plane of the 4f optical system. A beam splitter is placed inside the 4f optical system before the common focal plane. A phase spatial Zernike filter is placed in the common focal plane of the 4f optical system, said filter operating on reflection and being in the form of a flat mirror which consists of a fixed flat mirror component with a narrow opening at the centre and a movable flat mirror component placed in said opening while allowing displacement in the direction of the normal to the surface of the fixed component. The centre of the movable flat mirror component coincides with the optical axis of the 4f optical system.

Method of bi-metal coatings application out of metal sheets on part surfaces

Method of bi-metal coatings application out of metal sheets on part surfaces

Method of bi-metal coatings application on steel part surface includes transfer of the metal sheets from the consumable part of rub to the treated part surface during friction between them under pressure due to radial feed of rubs made with possibility of progressive and rotational motion in the tool assembly. Initial roughness of the treated part surface is brought to level of the true surface by microroughnesses cut off by the cutting edges on the work surfaces of the bronze rubs. Then process liquid is supplied to the treatment zone, and forces are applied for radial movement of the bronze rubs till their contact with the part, at that the bottom bronze monolayer is applied with simultaneous part strengthening using friction of the bronze rubs in the process liquid. The top brass monolayer is applied on surface of the bottom bronze monolayer of the treated part surface, at that the top monolayer is applied by friction of the brass rubs in the process liquid.

Simultaneous forming of thin yba2cu3o7-x films on two-sided dielectric substrates

Invention relates to forming of superconducting films on both surfaces of dielectric substrates. Invention allows production of uniform-depth superconducting films on both surfaces of the substrate in single process cycle. In forming of superconducting film structures from YBaCuO on both surfaces of the substrate by laser ablation process, substrate is revolved so that its every surface faces in turn the YBa2Cu3O7 target for 5÷7 second at 25-30 mm from the target.
