20120024764	Multifrequency Sieve Assembly for Circular Vibratory Separator - The invention is intended for sizing separation of difficult-to-screen powder materials and slurries. A sieve assembly includes a rigid frame, attached inside the separator housing, and upper and bottom sieves, stretched on the frame. The interface apparatuses are connected to the upper sieve, while actuator means—to the bottom sieve. The forced frequency of the vibrator is close to one of the natural frequencies of the bottom sieve. When the vibrator is operated, the actuator means interact with interface apparatuses, thus generating repeated collisions therebetween and mechanical impulses, which provide multifrequency excitation of the interface apparatuses and upper sieve. This ensures continuous self-cleaning of the upper sieve, intense loosening of the material bed and disintegration of the particle agglomerates. Separation capacity and products' quality substantially rises. In other embodiments presented sieve assembly includes buffer elements and inertial apparatuses, connected to the upper sieve.	02-02-2012

20090114393	DIVERTER VALVE - Apparatus for multi-zone wellbores that can by-pass upper hydrocarbon bearing zones and deliver fluid to lower hydrocarbon bearing zones. The apparatus can include at least one housing, and at least one port can be formed through the housing. An inner sleeve can be positioned within the housing. At least one cavity can be radially disposed on an outer diameter of the inner sleeve, and each cavity can be located within an annulus formed between the inner sleeve and the housing. A ball can be disposed within each cavity, and the ball can be adapted to selectively engage the port.	05-07-2009
20100163235	EFFICIENT SINGLE TRIP GRAVEL PACK SERVICE TOOL - A service tool and methods for performing subterranean hydrocarbon services in a wellbore. The service tool can include a body that having an aperture formed therethrough. A valve system can be connected to the body. The valve system can selectively form a flow path between a first portion of the aperture and a second portion of the aperture; a flow path between a first flow port formed through a first portion of the body, the aperture, and the outer diameter of the body; and/or a flow path between a channel formed in a portion of the body, a second flow port formed through a second portion of the body, and the second portion of the aperture.	07-01-2010
20110146984	CONSTANT PRESSURE OPEN HOLE WATER PACKING SYSTEM - A system for conveying fluid into a wellbore, including a tubular member, a packer, a hydrodynamic flow device, and a seal device. The tubular member is disposed in the wellbore through a first zone, a second zone, and a hydrocarbon producing zone of the wellbore. The packer is disposed adjacent to the tubular member, and is configured to at least partially isolate the hydrocarbon producing zone from at least one of the first and second zones. The hydrodynamic flow device is disposed around the tubular member and comprises a pump fluidly connected to a discharge in fluid communication with the first zone and an inlet in fluid communication with the second zone. The seal device is disposed around the hydrodynamic flow device to isolate a first annulus of the first zone from a second annulus of the second zone.	06-23-2011

20100216093	DENTAL IMPLANT - The invention provides a dental implant, characterized by a cylindrically threaded shaft section with at least a double lead thread. One lead thread is micro carved, while the other lead thread is carved with teeth of any shape, for instance V-shaped, buttress-shaped or square-shaped. The dimension of teeth increases gradually from zero in the lower part of the said implant (with constant or cone diameter) to approximately 0.1-0.2 of the diameter of the micro carving from the upper part of the said body implant. The maximal diameter of the said implant equals approximately 1.2-1.4 of that of the lower part. Thereto the internal body is supplied by a lead thread in order to block the said implant and may further be used for attachment of the key to turn in the said implant.	08-26-2010
