Patent number: 7455778Abstract: Systems, methods, and apparatus for desalinating water are provided. A vessel includes a water intake system, a reverse osmosis system, a concentrate discharge system, a permeate transfer system, a power source, and a control system. The concentrate discharge system includes a plurality of concentrate discharge ports. A water intake system installed on a sea-going vessel positioned on the surface of a body of water includes an apparatus for taking up seawater from the body of seawater. The apparatus includes a water intake member, a water intake positioned on the water intake member, and an impingement, entrainment, and entrapment mitigation device at least partially surrounding the water intake and including a plurality of apertures sized to prevent entry of marine organisms into the water intake.Type: GrantFiled: September 14, 2006Date of Patent: November 25, 2008Assignee: Water Standard Company LLCInventor: Andrew W. Gordon

Patent number: 7455770Abstract: A system and method for integrating microfluidic components in a microfluidic system enables the microfluidic system to perform a selected microfluidic function. A capping module includes a microfluidic element for performing a microfluidic function. The capping module is stacked on a microfluidic substrate having microfluidic plumbing to incorporate the microfluidic function into the system. An infusion pump for delivering a fluid from a fluid source may be integrated in a microfluidic chip using a capping module having pumping components formed therein.Type: GrantFiled: September 27, 2004Date of Patent: November 25, 2008Assignee: Cytonome, Inc.Inventors: John R. Gilbert, Manish Deshpande

Publication number: 20080223779Abstract: A strainer for an emergency core cooling system (ECCS) in a nuclear power plant comprises a perforated strainer element that is immersed in a reservoir of cooling water, which is drawn through the strainer element into the emergency core cooling system. The side of the strainer element in contact with the cooling water has a contoured configuration for disrupting the formation of a flat bed of fibrous material that can trap small particulate material intended to pass through the strainer element. Incorporating this strainer element into an ECCS strainer enables the strainer to be made more compact, because the debris bed need not be spread over an unduly large area to prevent excessive head loss from the debris load in the event of a reactor loss of coolant accident. The strainer also incorporates a modular construction that uses individual strainer disc modules. Each disc module includes a perforated first disc part having a central opening and a perforated second disc part also having a central opening.Type: ApplicationFiled: May 3, 2005Publication date: September 18, 2008Applicant: Continuum Dynamics, Inc.Inventors: Andrew E. Kaufman, Alan J. Bilanin

Publication number: 20080210621Abstract: The invention relates to a filter insert (36, 66) for cleaning machines, in particular continuous-flow dishwashers (10), in which a batch to be cleaned runs through at least one treatment zone. The at least one treatment zone is assigned a washing tank (12). The filter insert (36) has a number of longitudinal ribs (38) which run parallel to one another and delimit flumes (48).Type: ApplicationFiled: February 13, 2008Publication date: September 4, 2008Inventor: Bruno Gaus

Publication number: 20080173580Abstract: A filter system is described which comprises a vessel (10) containing a plurality of sets of discs (41). Each set of discs (41) comprises a number of discs (40) stacked one above the other. The discs (40) have grooves (50) on their opposite sides so that media to be filtered passes through the grooves and contaminants in the media are prevented from passing through the grooves or trapped by the grooves. A backwash system (25) is provided for supplying air to force liquid in the opposite direction through the grooves to wash any contaminant out of the grooves. An air vent (26) is provided for allowing compressed air to escape from the vessel (10) and an outlet (16) is provided for discharge of contaminant.Type: ApplicationFiled: May 31, 2005Publication date: July 24, 2008Applicant: ESCO PROCESS (ASIA PACIFIC) PTE LTDInventor: Teng Hee Leow

Publication number: 20080156712Abstract: The present invention relates to filters used to remove debris from water being sucked into a piping system. It has particular application use in nuclear power plants, which, after a loss of coolant accident, must pump cooling water back into the reactor core from a collection sump. This water may contain various types of debris that must be removed before the water is sent back into the reactor cooling system. There are restrictions on the allowable pressure drop across the strainer and the space available for installing this equipment. The finned strainer of the present invention addresses these issues while maximizing the quantity of debris filtered from the water.Type: ApplicationFiled: November 4, 2005Publication date: July 3, 2008Applicant: ATOMIC ENERGY OF CANADA LIMITEDInventors: David Bruce Rhodes, James Edward Allan McGregor
