Patent number: 7785360Abstract: An instrument for implanting an expandable cylindrical vascular prosthesis includes an outer tube and an inner tube which can be displaced relative to one another. The inner tube is longitudinally slotted on the distal end, at least in an area thereof, and ensheathes the stent with this area which includes the longitudinal slot. In order to implant the stent, the outer tube is retracted. The stent then expands with continuous retracting movement of the outer tube and the inner tube is pressed open along the longitudinal slot. Implantation is terminated, when the outer tube is retracted along the entire length of the stent. The implantation is reversible by pushing the outer tube forward, as long as the stent has not yet fully exited the instrument. In this way, the inner tube is constricted together with the stent, and compressed to an initial position.Type: GrantFiled: May 18, 2002Date of Patent: August 31, 2010Assignee: Merit Medical Systems, Inc.Inventor: Lutz Freitag

Patent number: 7785399Abstract: Systems and processes utilize one or more methods of providing overhead waste process heat to increase the feed temperature of the hot solvent stripping regeneration loop in an acid gas removal process. A heated rich solvent stream can be the primary feed for the hot solvent stripping regeneration loop, and one or more slip streams can be heated and then combined with the heated rich solvent stream to form a combined rich solvent stream prior to further processing in downstream units to remove acid gas from the solvent. A first slip stream can be heated in a stripper gas heat exchanger by heat exchange with a stripped gas stream. A second slip stream can be heated in a regenerator exchanger by heat exchange with an acid gas stream. A third slip stream can be heated in a recycle gas exchanger by heat exchange with a compressed recycle gas stream.Type: GrantFiled: January 16, 2009Date of Patent: August 31, 2010Assignee: UOP LLCInventors: Richard Huang, Lamar A. Davis, William J. Lechnick, Xin Zhu

Patent number: 7785400Abstract: An apparatus for separating natural gas from production streams comprising a liquid dispersion of water, sand, and natural gas is provided for. The separator comprises a vessel having an interior surface defining a spherical interior space. The interior space allows a production stream introduced therein to experience a velocity drop sufficient to allow separation of the natural gas from the sand and water components. The separator also comprises a stream inlet port in the vessel, a liquid drain in the lower end of the vessel, and a gas outlet port at the upper end of the vessel remote from the stream inlet port. A baffle is mounted in the interior of the vessel in the path of the production stream between the stream inlet port and the gas outlet port. The baffle is effective to spread and direct a high pressure production stream introduced into the interior space via the stream inlet port downward toward the liquid drain.Type: GrantFiled: June 30, 2009Date of Patent: August 31, 2010Assignee: Sand Separators LLCInventors: Emmett Ronald Worley, Shirley Royce Green

Patent number: 7785401Abstract: The present invention relates to a fluid separation device (10) for separating fluid, oil and oil spray from a gas. This fluid separation device (10) comprises a base carrier (21) in which fluid separator elements (20) in the form of flow-through tubes with worm-like segments (23) arranged therein, are integrated. The worm-like segments (23) at the same time form spiral flow paths (25) for the gas. They have a maximal length of half a pitch of the worm-like segment (23) so that the base carrier (21) together with the associated fluid separator elements (20) may be formed as one piece. Several base carriers may be arranged one after the other in a manner such that individual fluid separator elements of various base carriers form a common flow path for the gas.Type: GrantFiled: March 8, 2005Date of Patent: August 31, 2010Assignee: REINZ-Dichtungs-GmbHInventors: Jürgen Wagner, Dieter Grafl, Armin Praska, Kai-Uwe Lemke

Patent number: 7785402Abstract: A support framework for containing a media that is used to remediate corrosive vaporous pollutants in an air stream. The support framework is situated within a plenum and comprises two concentric open-lattice weave frameworks made from corrosion resistant fiberglass reinforced plastic “FRP”. The frameworks are of differing diameters and the media is placed into and contained within the open space formed between the inside wall of the outer framework and the outside wall of the inner framework. The open-lattice weave design allows a greater radial flow through the media per unit of time, doing so with less pressure drop and using less energy than the prior art. The use of FRP to form the framework walls allows creation of large units that are suitable for use in municipal and industrial settings, which was not possible previously.Type: GrantFiled: May 7, 2007Date of Patent: August 31, 2010Inventors: Martin J. Crawford, Jeff Jones

Patent number: 7785403Abstract: An air purifier includes a main frame, a discharging device, a dust collection device and a voltage generator. The discharging device has a discharging portion and is installed in the main frame. The dust collection device has a dust collection portion and is installed in one side of the discharging device. The air purifier can produce ozone, negative ions and static electricity by moving the discharging portion and the dust collection portion and receiving suitable voltage. The voltage generator, the discharging portion, and the dust collection portion accomplish conduction. Production of ozone, negative ions and static electricity occurs according to separation between the discharging portion and dust collection portion, as well as the particular environment of operation, thereby improving air quality.Type: GrantFiled: August 22, 2007Date of Patent: August 31, 2010Inventors: Chieh Ouyang, Wei Ouyang

Patent number: 7785404Abstract: An air purifier includes a housing, a high voltage power supply, a first electrode assembly in which a wire-like first electrode is either the only first electrode or, alternatively, is spaced sufficiently far from any other such first electrodes so as to avoid undesirable effects upon each other, and a second electrode assembly in which there are a plurality of blade-like second electrodes. The air purifier can be of the type in which air flows through the housing as a result of electro-kinetic effects. To increase air flow velocity, the voltage between first and second electrodes is relatively high, such as 23-50 kV, and the first and second electrodes are accordingly spaced apart a relatively great distance, such as at least 30 mm.Type: GrantFiled: October 2, 2006Date of Patent: August 31, 2010Assignee: Sylmark Holdings LimitedInventors: Shengwen Leng, Guangsheng Liu

Patent number: 7785408Abstract: A particle collector comprises a housing defining an enclosed chamber. An inlet opening in the housing provides fluid communication between a source of gas and particles and the chamber and an outlet opening provides fluid communication between the chamber and the exterior of the housing. The outlet opening is connected to a pump for drawing gas and particles through the housing from the inlet opening to the outlet opening. A collecting member having an adhesive on at least a portion of the surface is disposed in the chamber between the inlet opening and the outlet opening. The adhesive surface of the collecting member is positioned adjacent to the inlet opening. When gas and particles are drawn through the housing, the inlet opening directs a stream of gas and particles at the surface of the collecting member. Particles having an aerodynamic equivalent diameter of less than about 2.5 ?m are captured.Type: GrantFiled: May 2, 2008Date of Patent: August 31, 2010Assignee: Environmental Monitoring Systems, Inc.Inventors: John L.
