20090078575 | METHOD FOR VACUUM-COMPRESSION MICRO PLASMA OXIDATION AND DEVICE FOR CARRYING OUT SAID METHOD - The inventive method and device for vacuum-compression micro plasma oxidation relate to electrochemical processing of metal, in particular to micro plasma treatment in electrolyte solutions. The aim of said invention is to develop a method for obtaining qualitatively homogeneous coatings by micro-plasma oxidation on large-sized parts, including irregular shaped parts, or simultaneously on a great number of small parts. The second aim of the invention is to design a device for processing parts, having an extended surface area, by using low-power supplies. The inventive method for vacuum-compression micro-plasma oxidation of parts consists in dipping a processable part into an electrolyte solution pre-filled in a sealed container, in generating micro-plasma discharges on the surface of said part and, subsequently, in forming a coating, wherein the micro-plasma discharges are formed in low-pressure conditions above the electrolyte solution. The device for carrying out said method comprises means for forming vacuum in the electrolyte-containing container and additional means for pumping air. | 03-26-2009 |

20130276587 | METHOD FOR PRODUCING A COKING ADDITIVE BY DELAYED COKING - This invention relates to the field of oil refining and, in particular, to a delayed coking process that produces coke with a volatile substances content of 15-25% for use as a coking additive in a coal coking charge in the production of metallurgical coke. The invention is directed towards increasing the content of volatile substances in coke and increasing the efficiency of a plant. The method comprises preheating a primary raw material, mixing the latter with recycle in a tank in order to form a secondary raw material, heating the secondary raw material to 455-470° C. and supplying the latter to a coking chamber, and coking to form a coking additive. It is expedient to feed an antifoaming additive into the coking chamber 3-5 hours before coking is finished. It is preferable to feed in the antifoaming addition agent at two-four points around the perimeter of the coking chamber. | 10-24-2013 |
20140246302 | METHOD FOR DELAYED COKING OF OIL RESIDUES - The invention relates to the petroleum-processing industry, in particular, to a retarded coking process directed to the production of gas oil fractions (light gas oil and two types of heavy gas oil). The method comprises heating a starting stock, feeding same into an evaporator for mixing with recycled material and forming a secondary stock, coking the secondary stock and fractionating the resulting coking products in a rectification column, thereby producing gas, petrol; light and heavy coking gas oils, and bottoms. Heavy coking gas oil is used as the recycled material. The method envisages feeding cooled heavy gas oil to mass-exchange devices in the lower part of the rectification column, and feeding a metered quantity of cooled light gas oil to mass-exchange devices in the upper part of the rectification column. The quantity of cooled light and heavy gas oils which can be fed in changes depending on the required quantity and quality of the light and heavy gas oils and bottoms being produced. | 09-04-2014 |

20080287710 | Methods for the preparation of chemically misaminoacylated tRNA via protective groups - The present invention relates to methods for the preparation of chemically aminoacylated tRNAs for the purpose of introduction of markers into nascent proteins. The present invention also relates to methods for the non-radioactive labeling, detection, quantitation and isolation of nascent proteins translated in a cellular or cell-free translation system utilizing chemically aminoacylated tRNAs. tRNA molecules are misaminoacylated with non-radioactive markers which may be non-native amino acids, amino acid analogs or derivatives. Markers may comprise cleavable moieties, detectable labels, reporter properties wherein markers incorporated into protein can be distinguished from unincorporated markers, or coupling agents which facilitate the detection and isolation of nascent protein from other components of the translation system. | 11-20-2008 |
