Patent number: 8511512Abstract: A chemical product dispenser that controls dispensation of a chemical product based on a change in weight of the chemical product remaining in the dispenser includes an isolation mechanism. The dispenser includes a weight measurement instrument, such as one or more load cells, that measure the weight of the chemical product remaining the dispenser. The isolation mechanism is configured to lift the chemical product from a lowered position in which the weight of the chemical product is fully supported by the load cell(s) to a raised position in which the weight of the chemical product is fully supported by the isolation mechanism. When in the raised position, the dispenser may be loaded with a supply of chemical product with a reduced risk of damage to the weight measurement instrument.Type: GrantFiled: January 7, 2010Date of Patent: August 20, 2013Assignee: Ecolab USA Inc.Inventors: Brian P. Carlson, Scott R. Limback, Joshua J. Lanz

Patent number: 8460625Abstract: An exhaust gas purification apparatus for an engine is provided with a filter arranged in an exhaust passage of the engine, and a regeneration control unit for regenerating the filter by burning the particulate matters accumulated in the filter. The control unit may include an over-accumulation state determination unit and a switch. The over-accumulation state determination unit determines over-accumulation of the particulate filter in the filter when the particulate matter is over-accumulated in the filter. The switch switches a regeneration temperature for regenerating the filter between a first regeneration temperature at which a normal regeneration is performed and a second regeneration temperature which is lower than the first regeneration temperature. The control unit is connectable to a command unit when the particular matter is over-accumulated in the filter, so that the switch is forcibly operated toward the second regeneration temperature.Type: GrantFiled: January 26, 2011Date of Patent: June 11, 2013Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Ko Takayanagi, Keisuke Okuda

Patent number: 8449840Abstract: Provided is a dispensing device capable of removing bubbles reliably. In this dispensing device, deaerated water is fed by a water feed pump to the inside of a pipeline up to the vicinity of the leading end of a dispensing nozzle. A water feed valve disposed near a dispensing pump is closed to establish a deaerated water space opened on the leading end side of the dispensing nozzle. The dispensing pump is activated on the space, thereby causing the dispensing nozzle to perform suction and exhaust actions. The dispensing device comprises a vacuum means connected to the space through the water feed valve thereby maintaining a vacuum state. In case the deaerated water space is cleared of the bubbles, the cleared water space is brought, by opening a change-over valve, into communication with a pipeline having a vacuum means connected thereto, thereby bringing the space into the vacuum state.Type: GrantFiled: March 19, 2009Date of Patent: May 28, 2013Assignee: Beckman Coulter, Inc.Inventor: Isao Saegusa

Publication number: 20130108528Abstract: Systems and methods are disclosed that include an exhaust gas stream produced by an engine and an aftertreatment system including an SCR catalyst element receiving at least a portion of the exhaust gas stream. An exhaust outlet flow path has an inlet fluidly coupled to the exhaust gas stream at a position downstream of at least a portion of the SCR catalyst element that bypasses at least a portion of exhaust gas stream to provide for compositional measurement of the exhaust gas with a compositional sensor located downstream of a diagnostic catalyst positioned in the exhaust outlet flow path.Type: ApplicationFiled: October 31, 2012Publication date: May 2, 2013Applicant: Cummins Inc.Inventor: Cummins Inc.

Publication number: 20130084216Abstract: The heat treating furnace for the gas reaction includes an outer body, an inner body, a heating mechanism, gas supplying mechanism, and a controller. Using the controller to control the amount of gas supply effectively keeps the first pressure (P1) in the gas circulation chamber outside the inner body greater than the second pressure (P2) in the reaction chamber inside the inner body all the time. In this way, the flow rate of gas inlet, reaction rate, cooling rate can be facilitated, and the uniformity of the thin film and the operational safety can be improved.Type: ApplicationFiled: December 28, 2011Publication date: April 4, 2013Inventors: Ying-Shih HSIAO, Toshiaki YOSHIMURA
