Patent number: 6655150Abstract: The present invention relates to a method for removing and recovering CO2 from exhaust gas from a power and/or heat generating plant (a main power plant) by chemical absorption and desorption respectively, where the exhaust gas is fed to an absorber using a chemical absorbent where the CO2 is absorbed in said absorbent and a CO2-depleted exhaust gas stream is formed. The CO2 rich absorbent is further fed to a desorber where CO2 is removed from the absorbent, and the absorbent essentially free of CO2 is recirculated to the absorber and desorbed CO2 gas is discharged off. The exhaust gas is cooled and recompressed to an elevated pressure, in a compressor in a secondary power plant integrated with the main power plant, said absorber, and said desorber, before entering the absorber. The CO2-depleted exhaust gas emerging from the absorber is reheated and further expanded in an expander in said secondary power plant.Type: GrantFiled: November 20, 2001Date of Patent: December 2, 2003Assignee: Norsk Hydro AsaInventors: Knut Ingvar Åsen, Dag Arne Eimer

Patent number: 6655191Abstract: In a method for detecting knocking combustion during the operation of an internal combustion engine with a device for measuring the ionic current, the raw ionic current signal or the evaluated value of the knocking intensity are normalized. This enables the value of the knocking intensity to be reliably compared with a threshold value. The normalization avoids the falsifying influence of large intensity fluctuations of the raw ionic current signal from one combustion cycle to the next without any relation to the true knocking intensity.Type: GrantFiled: June 27, 2001Date of Patent: December 2, 2003Assignees: DaimlerChrysler AG, Temic Telefunken microelectronic GmbHInventors: Peter Hohner, Klaus Knolmayer, Joerg Miroll, Linhard Niemetz

Patent number: 6655192Abstract: A permeameter provides normal and lateral permeability measurements on porous materials. The permeability measurements can be made on compressed or uncompressed samples and can be made at room temperature or at elevated temperatures. A wide variety of fluids, gas or liquid, can be used as the penetrating test fluid depending on the application and the porosity of porous sample. The penetrating test fluid is forced through the sample under pressure. The load, the fluid displacement, and the time are recorded and used in the calculations of permeability, porosity, pore size distribution, average pore size and the number of pores per unit area.Type: GrantFiled: October 10, 2001Date of Patent: December 2, 2003Assignee: BorgWarner Inc.Inventor: Bulent Chavdar

Patent number: 6655193Abstract: A leakage detecting device has a cover, a first cup and a second cup. The cover is mounted on the opening of the water tank and has a through hole. The first cup is connected to the cover and communicates with the through hole in the cover. A tortuous air channel is defined in the first cup. The second cup is mounted on the first cup and has a second tortuous air channel communicating with the first tortuous air channel in the first cup. Accordingly, the leakage of cylinders of the vehicle engine can be precisely detected from the water tank of the vehicle.Type: GrantFiled: September 17, 2002Date of Patent: December 2, 2003Inventor: Lai-Chen Liu

Patent number: 6655194Abstract: The present invention relates to a miniature rheometer, a parallel rheometer, and improved force sensor elements which may advantageously be used in combination with the miniature rheometer and the parallel rheometer. The miniature rheometer is adapted to determine rheological characteristics of materials which are provided in the form of small quantity samples. The miniature rheometer comprises an actuating element, a sensing element and a feedback circuit to provide rebalance of the shear force applied by the sample to the sensing element, which insures an exceptional stiffness in determining the shear strain so as to allow measurements of high accuracy. The parallel rheometer of the present invention allows simultaneous measurements of a plurality of samples so as to allow of a plurality of samples within a short time period. The force sensor element according to the present invention allows simultaneous measurement of a shear force and a normal force applied to the sensor element.Type: GrantFiled: October 1, 2002Date of Patent: December 2, 2003Assignee: Symyx Technologies, Inc.Inventors: Damian Hajduk, Eric Carlson, Ravi Srinivasan

Patent number: 6655195Abstract: Process for determining disturbances of a moisture cross profile of a fibrous material web in a paper making machine, a paper making machine, and a measuring arrangement for measuring the disturbances, the process including guiding the fibrous material web by way of at least one water-permeable belt and collecting and draining off water released from the belt. The water is collected by several sections separated from one another. The process further includes measuring per time unit, the amount of water in each section, wherein the sections extend at right angles to a web running direction over only a partial section of the fibrous material web. The paper making machine includes at least one water-permeable belt, the belt being wrapped around a roll. The measuring arrangement includes a water collection device having the form of one of a trough or channel.Type: GrantFiled: December 31, 2001Date of Patent: December 2, 2003Assignee: Voith Paper Patent GmbHInventors: Joachim Grabscheid, Ulrich Begemann, Oswald Satzger, Wolfgang Mayer, Ralf Rziha, Wolfgang Bamberger, Georg Kleiser, Thomas Rühl

Patent number: 6655197Abstract: The present invention is directed towards an apparatus for monitoring and displaying characteristic values of certain parameters of the automatic transmission fluid in the automatic transmission system or the automatic transaxle system of a land motor vehicle. The apparatus has several elements to it: a sensor, which is placed into a conduit carrying the automatic transmission fluid to read the characteristic values, microprocessor, which receives these values, and finally a readout component, which displays them. The characteristic values of the automatic transmission fluid may include the values for the flow rate, pressure, temperature, and others. The readout component may be a diagnostic tool used for maintenance and/or repair or a dashboard display component used by the driver or the operator of the motor vehicle while the vehicle is in motion.Type: GrantFiled: July 23, 2001Date of Patent: December 2, 2003Assignee: Sonnax Industries, Inc.Inventor: Ben Wallace

Patent number: 6655199Abstract: An electronic foot pedal vehicle control system includes a foot pedal of rigid one-piece molded plastic construction having a base and a pedal arm cantilevered from the base. An electronic subassembly is insert molded into the base of the foot pedal, and includes a force sensor disposed in the base adjacent to the pedal arm for providing an electrical sensor signal as a function of force applied to the pedal arm by a vehicle operator. Electronic circuitry is responsive to the sensor signal for providing a pedal output signal to control at least one variable of vehicle operation. The electronic circuitry preferably has programmed hysteresis characteristics so as to allow limited force variation on the pedal without changing the output signal from the electronic circuitry.Type: GrantFiled: June 20, 2002Date of Patent: December 2, 2003Inventor: Rex L.
