20090185937	POSITIVE-DISPLACEMENT ROTARY MACHINE - The invention relates to rotary machines provided with nonparallel axes of a rotor and pistons. The inventive positive-displacement rotary machine comprises a body, the working surface of which is embodied in the form of a part of a segment of sphere, a rotor which is provided with a working surface of revolution and which is arranged in the body in such a way that it is rotatable, a ring-shaped concentric working cavity formed by the body and the rotor, a separator which is embodied in the form of a wobble plate, is fixedly arranged in the body and divides the working cavity into two parts. The working surface of the rotor is provided with at least one slot which is embodied along the geometrical axis of rotation thereof and in which a piston in the form of a part of disk is placed in such a way that it is enabled to perform rotational oscillations in the plane thereof. Each piston is provided with a sealable through-slot for the separator passage. At least one through passage, which makes it possible to position input and output ports on the opposite sides of the separator by mutually spacing them along the axis of the rotor, is embodied on one of the areas of the separator, thereby simplifying the combination of stages. Said inventions make it possible to increase the synchronising reliability of the working members of a spherical machine and to use it in a down-hole high-speed multistage high-pressure pump.	07-23-2009

20090016972	Oral cavity care curative and prophylactic composition - The invention relates to stomatology and perfume industry in particular to therapeutic formulation for oral cavity care. The invention refers to oral hygiene means and can be applied for preparation of medical and prophylactic tooth-pastes, gels, liquids for oral care as well as other compositions like chewing gums, jellies, etc. Formulation containing orally applicable active and inert components involves bromelain in amount of 0.01÷1 wt %, xylitol 1.5÷20 wt %. At best bromelain content is 0.1—0.8 wt %, xylitol content—2.2-18 wt %. For attaining remineralizing effect formulation contains anti-carious mineral additive 0.05-3.0 wt % of the list of active components. At best anti-carious mineral additive content is 0.2-2.5 wt %. There are used calcium glycerophosphate and inorganic or organic magnesium salt as anti-carious mineral additive. It is acceptable to use sodium monofluorphosphate, potassium monofluorphosphate, calcium monofluorphosphate or magnesium monofluorphosphate in amount of 0.5-1.5 wt % as anti-carious mineral additive Optimum concentration is 0.8-1.1 wt %.	01-15-2009
20090041684	FORMULATION FOR PROPHYLAXIS OF ORAL CAVITY DISEASES - The invention relates to medicine, namely, to stomatology, in particular, to formulation for prophylaxis of oral cavity diseases. The formulation comprises: drinking water, glycerol, xylitol, silica, xanthan gum, methylparaben, propylparaben, titanium dioxide, perfume, bromelain, sodium saccharin, sodium lauryl sulfate or alkylamidobetain, calcium glycerophosphate, and magnesium chloride or glycerophosphate magnesium at following component ratio, % wt.: glycerol—20-25; xylitol—10-14; i 10 silica—22-26; xanthan gum—1.2-1.4; methylparaben—0.2-0.3; propylparaben—0.08-0.12; sodium saccharin—0.1-0.3; titanium dioxide—0.2-0.4; perfume—0.7-1.0; bromelain—0.1-0.7; sodium lauryl sulfate—1.2-1.4 or alkylamidobetain—1.2; calcium glycerophosphate—0.6-1.0; magnesium chloride—0.08-0.16 or magnesium glycerophosphate—0.16; and water—up to 100.	02-12-2009

20110235935	METHOD FOR EVALUATING QUALITY OF IMAGE REPRESENTING A FINGERPRINT PATTERN - A method for evaluating quality of image representing a fingerprint pattern is provided, the method including performing a filtering process on a region of the image including a digital filtering of the selected region successively performed a certain number of times. According to the method, convergence of said filtering process is determined, and the image within the region is classified as an image with identifiable pattern if the filtering process is convergent, whereas the image within the region is classified as an image with unidentifiable pattern if the filtering process is nonconvergent. The digital filtering is performed using a filter adapted to at least one of the following local image parameters: curvature of dermal ridges, scale and tilt angle of dermal ridges.	09-29-2011

20110246522	METHOD FOR FORMING A REFERENCE LIST OF MARKS, DATABASE AND METHOD FOR FORMING SAID DATABASE - The present invention relates to a method for forming a mark reference list using a database including a register of mark-forming objects in the form of a sample array, and a mark array. According to this method, a mark is compared with each sample of the sample array, match indexes of the mark and said each sample are determined based on said comparison, and a list of high match indexes of the mark and the samples is formed. The decision that a mark should be included into the reference list is made, if the match index of a query sample and the mark is higher than the lowest index of the list of high match indexes of the mark and the samples.	10-06-2011
