Patent number: 7335311Abstract: An apparatus for treating sludge, comprises a press for dewatering the sludge, a compaction device for receiving and compacting sludge dewatered by the press, a shredder for receiving and shredding sludge compacted by the compaction device, and a tube conveyor for conveying shredded sludge from the shredder. The press is controlled to vary the flow rate of the sludge in response to at least one sensed operational parameter of the press, such as the momentary power for operating the press, pressure in the sludge in the press, sludge concentration in the press, sludge feed flow to the press or separated water flow from the press.Type: GrantFiled: October 13, 2004Date of Patent: February 26, 2008Assignee: Nordic Water Products ABInventor: Jesper Christophersson

Patent number: 7335312Abstract: A centrifuge with combinations of multiple features is disclosed. In one aspect, a centrifuge for removing more dense material from a fluid medium includes a fluid separation wall placed within a sleeve. The fluid separation wall rotates around the axis of rotation. A receptacle aids in separation of the more dense material from the fluid medium. The receptacle defined in a part by a respective geometry and a respective shape. An opening extends from the void area to the outer surface to transport the more dense material to the containment zone. An excitation apparatus associated with the receptacle creates a vibration within the receptacle. The centrifuge may further include a valve ring including a valve orifice the valve ring having a first position which blocks the more dense material from exiting the receptacle and a second position that allows the more dense material to move into the containment zone.Type: GrantFiled: September 21, 2005Date of Patent: February 26, 2008Assignee: Phase Inc.Inventors: Curtis Kirker, Berkeley F. Fuller

Patent number: 7335313Abstract: Disclosed is a vortex-based centrifugal separator for removing solids from a liquid/solids fluid stream in two stages. A fluid stream under pressure is introduced at the top of the cylindrical separator at a tangential angle forming helical downward flow. The first stage uses a centrally-located spin plate for reversing the cleaner interior flow of the vortex back upward, while the heavier solids settle at the bottom of the chamber for periodic removal. In the second stage, a plurality of louvered slots in an upper discharge pipe remove finer solids from the exiting upward fluid flow prior to discharge.Type: GrantFiled: April 5, 2006Date of Patent: February 26, 2008Assignee: Griswold ControlsInventor: Emmanuel G. Moya

Patent number: 7335314Abstract: An implantable medical device, such as a stent or graft, having asperities on a designated region of its outer surface is disclosed. The asperities can serve to improve retention of one or more layers of a coating on the device and to increase the amount of coating that can be carried by the device. The asperities can be formed by using a stream of pressurized grit to roughen the surface. The asperities can also be formed by removing material from the outer surface, for example, by chemical etching with or without a patterned mask. Alternatively, the asperities can be formed by adding material to the outer surface, for example, by welding powder particles to the outer surface or sputtering.Type: GrantFiled: August 4, 2004Date of Patent: February 26, 2008Assignee: Advanced Cardiovascular Systems Inc.Inventors: Steven Z.
