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 |
20130011286 | VOLUMETRIC ROTARY MASHINE - A hinged joint is formed on a volumetric rotary machine with a spherical working cavity formed between a spherical rotor part and the spherical surface of the body, between a piston, which is mounted in such a way as to enable rotary oscillations relative to the rotor in the plane passing along the axis of rotation of the rotor, and a rotor, which is mounted in such a way as to enable rotation about the spherical rotor part. This solution has made it possible to increase the reliability, service life and thermal stability of machines of this type. In addition, helical channels for communication between symmetrical working chambers and channels within the rotor for connecting the working chambers to the working-medium inlet and outlet openings are formed inside the spherical rotor part. This solution has made it possible to increase the specific power of the machine. | 01-10-2013 |
20130202469 | POSITIV-DISPLACEMENT ROTARY MASHINE - A positive-displacement rotary machine comprises a housing a rotor installed in the housing with the a capability of rotation, a separator installed in the housing, having a guide part with a hole for the rotor; a piston installed in the a groove of the rotor with the a capability of making rotary oscillations relative to the rotor around an axis that intersects the an axis of rotation of the rotor, having at least one slot into which the guide part of the separator enters, a sphere-like working cavity formed around the rotor, which the guide part of the separator, during interaction of the hole with the rotor, divides into chamber-forming cavities of variable cross section, each of which is divided by the piston into working chambers. There is a passage for the a working fluid that permits the working thud to bypass the minimal cross section of the chamber-forming cavity; and input and output ports of the working fluid. | 08-08-2013 |

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 |
