Patent number: 7590196Abstract: The present invention provides a method, circuit and system for phase-sensitive detection and recovery of complex signals of interest using a double reference lock-in detector. A double reference lock-in detector may have two or more reference signal sources whose signals are first combined, producing a composite (e.g., inter-modulation) reference signal. This signal is then mixed with an input signal, yielding the desired selectivity at the frequency(ies) of interest. A second embodiment uses external reference signals, synchronizing internal references to these before combining the reference signals. Such detectors may used in chiral detection systems for recovering predetermined signals of interest associated with chiral properties of a sample being tested.Type: GrantFiled: May 3, 2005Date of Patent: September 15, 2009Inventor: Phillip R.

Patent number: 7410581Abstract: A cross flow filtration apparatus for nanofiltration or reverse osmosis has pressure vessels with a plurality of filter cartridges in each vessel. A feed port is provided at an intermediate position on the side of the vessel, and two permeate flows or branches exit opposite ends of the vessel, and the first branch has a characteristically high “upstream” flux and quality, while the second is of lesser flux and/or quality. The system provides a high degree of moduarity, enhancing flux or yield at a reduced driving pressure or overall pressure drop. Centered or off-center port, and a stop or valve in the permeate stream may apportion flows between the two outlets. Staged systems may employ a first stage bypass to achieve a target quality with increased yield. A flow divider or adaptor permits the cartridges to fit and seal in the vessel and an installation tool or sleeve may facilitate installation or replacement of cartridges having a directional perimeter seal.Type: GrantFiled: November 5, 2002Date of Patent: August 12, 2008Assignee: GE Infrastructure, Water & Process TechnologiesInventors: John W.

Patent number: 7264737Abstract: A water treatment system and method including a membrane-based boron removal unit includes a boron analyzer for detecting the concentration of boron in a treatment stream. The boron removal unit can be a reverse osmosis (RO) or electrodeionization (EDI) treatment unit. A controller responds to the detected boron concentration to control an operation of the RO or EDI units. In an EDI system, the controller may adjust current or voltage supplied to match current to changes in ionic load and maintain a portion of the dilute cell in a substantially regenerated state. In an RO system, the controller may control the high pressure side flow rate, the brine blowdown rate, the product water permeation rate, pH, or feed rate of chemicals in response to the detected boron concentration value.Type: GrantFiled: October 7, 2002Date of Patent: September 4, 2007Assignee: Ionics, IncorporatedInventors: Richard D. Godec, Robert J. Ritz, William W. Carson, Thomas J. Susa

Patent number: 7107774Abstract: Methods and apparatus are disclosed for starting up a combined cycle plant using a startup duct to connect an auxiliary engine to the inlet of a plurality of HRSGs or other heat recovery systems. Each HRSG is fed by a combustion turbine. Dampers are supplied to isolate each HRSG from the startup duct and its CTG. The auxiliary engine is also ported to a stack allowing simple cycle operation. Dampers are also supplied to isolate the auxiliary engine from the startup duct and from its stack. During startups, the large CTGs will be isolated and the auxiliary engine will be connected to the HRSGs and started, allowing the HRSG to pressurize. As each HRSG pressurizes, it is isolated from the startup duct and connected to its respective CTG. The CTG is then started and loaded. The auxiliary engine is turned off and isolated when the last HRSG pressurizes.Type: GrantFiled: June 17, 2004Date of Patent: September 19, 2006Assignee: Washington Group International, Inc.Inventor: Michael J.

Patent number: 7094325Abstract: Apparatus and method are disclosed for introducing ion exchange or other particulates into compartments of an already-assembled electrodeionization or comparable stack by modulating a flow of slurry into the compartments with slugs of gas such as air. The air propels liquid through the cells, scavenging ponded liquid so that the particulates (which are retained, e.g., by a strainer or obstruction, in compartment of the apparatus) are deposited as well-packed beds to fill the compartments. Pressurized air filling protocols may deliver discrete slugs of slurry between bursts of air, and the direction of filling may be periodically reversed to diminish particle bed non-homogeneities or settling gradients that arise during transport. The slugs of air may be applied in the direction of slurry flow, in the reverse direction, or both. Different slurries may be transported in a sequence to form layered and packed beds of enhanced utility.Type: GrantFiled: January 31, 2003Date of Patent: August 22, 2006Assignee: Ionics, IncorporatedInventors: Bernard R. Mack, Keith J. Sims, William W. Carson, Richard I. Parent
