Publication number: 20100162780Abstract: Methods and apparatuses for depositing agents relatively deep within pores of bio-char. Bio-char is first produced in an airtight oven by heating biomass feedstock. The bio-char is then cooled and steam is diffused into the pores of the bio-char.

The liquid bath cools the char to below the condensation temperature of the steam, whereupon the condensing steam generates a partial vacuum within the pores, drawing the liquid into the pores. The bio-char is then removed from the liquid bath and dried so that the liquid within the pores evaporates, leaving behind the soluble agent. Accordingly, the invention yields bio-char that has soluble agent embedded relatively deep within its pores.Type: ApplicationFiled: December 31, 2008Publication date: July 1, 2010Inventor: Gerald C.

The method also includes measuring a first temperature and a second temperature. The first temperature is the temperature of the gas flowing through the first passageway of the bypass block and the second temperature is the temperature of gas flowing within the second passageway. The method also includes adjusting the bypass valve to divert a portion of the gas flowing through the second passageway to create temperature conditions substantially similar to conditions that are created due to a compressor valve leak.Type: ApplicationFiled: December 30, 2008Publication date: July 1, 2010Inventors: Sean Summers, Brian Howard, Roger Hala, John Grant, David R.

Publication number: 20100162798Abstract: In a method for determining the viscosity of fluids, especially liquids, the fluid is brought into and moved through a tapering gap bounded by two opposite wall surfaces. Accordingly, a distance or the change of the distance between the opposite wall surfaces is measured by pressure exerted by the material moved through the preferably steadily tapering or narrowing gap onto the walls and is used or evaluated as a measurement value for the viscosity of the fluid.Type: ApplicationFiled: April 22, 2008Publication date: July 1, 2010Applicant: ANTON PAAR GMBHInventor: Josef Gautsch

Publication number: 20100162799Abstract: The present invention relates to a device for a torque meter for determining of for example viscosity, shearing force or concentration of liquids or suspensions, and comprising two elastically connected concentric axles, one external hollow axle (6) through which an inner meter axle (5) extends, on which latter an element (4) responsive to the measurement medium (3) is located. According to the invention the axles (6, 5) are propelled by an electrical motor (9, 10), said motors are at least on average continuously propelled at equal rotational speed at the same time the phase between the two is being controlled irrespective of the applied speed and torque, wherein the torque is possible to measure through the degree of load at the motor (10) propelling the inner axle (5), which is transformable to a suitable out signal.Type: ApplicationFiled: December 19, 2007Publication date: July 1, 2010Inventors: Niclas Andersson, Joakim Kullander, Peter Lundberg, Peter Adrian

Publication number: 20100162801Abstract: In order to obtain a temperature gradient elution method which is rapid and accurate, a mobile phase (1) is supplied through two mobile-phase flow channels (2a) and (2b), mixed together, and introduced into the column (15) while the column (15) is made adiabatic. In this operation, the temperature of the mobile phase in one mobile-phase flow channel, i.e., the channel (2a), is regulated to a constant temperature higher than the upper limit of the target temperature range to be obtained in the column (15), while the temperature of the mobile phase in the other mobile-phase flow channel, i.e., the channel (2b), is regulated to a constant temperature lower than the lower limit of the target temperature range in the column (15). By controlling the flow rates in the two mobile-phase flow channels (2a) and (2b), the proportion in which these mobile-phase portions are mixed is changed with time to thereby change the temperature of the mobile phase in the column (15) with time.Type: ApplicationFiled: February 9, 2006Publication date: July 1, 2010Inventors: Morimasa Hayashi, Yoshihiro Hayakawa

Publication number: 20100162802Abstract: It is an object of the present invention to provide a steam turbine test facility including a test steam turbine, in which the behavior of an actual steam turbine can be precisely simulated and the efficiency of performance test can be improved. A steam turbine test facility 1 includes a test steam turbine 2 which simulates the behavior of a real steam turbines 11 included in the steam turbine plant 10, and a motor-generator 4 connected to the test steam turbine 2. A control unit 5 included in the motor-generator 4 controls the motor-generator 4 to change the rotational speed of the test steam turbine 2 based on an arbitrarily set speed change pattern. The speed change pattern is set such that the test steam turbine 2 in the load disconnection state simulates a time-profile of the rotational speed of the steam turbines 11 with the load disconnected.Type: ApplicationFiled: December 22, 2009Publication date: July 1, 2010Applicant: HITACHI, LTD.Inventors: Tateki NAKAMURA, Takeshi KUDO, Naoaki SHIBASHITA

Publication number: 20100162803Abstract: A method of detecting during a combustion cycle a peak value of pressure in a cylinder of an internal combustion engine includes providing and installing on the engine body an accelerometer that generates an acceleration signal representing vibrations of the engine body. The acceleration signal is filtered by comparing the band-pass filtered replica of the acceleration signal to a threshold. When the threshold is surpassed, a pressure peak is detected and flagged.Type: ApplicationFiled: December 28, 2009Publication date: July 1, 2010Applicant: STMicroelectronics S.r.l.Inventors: Ferdinando Taglialatela Scafati, Nicola Cesario, Domenico Porto, Bianca Maria Vaglieco, Simona Silvia Merola

Publication number: 20100162804Abstract: The invention relates to a method for checking the function of a tank venting valve between the intake manifold of an internal combustion engine and a fuel tank or a fuel vapor reservoir in which the tank venting valve in operation of the internal combustion engine is opened several times and is closed again after a short opening time and in which during repeated opening and closing the time characteristic of a quantity which is dependent on the opening state of the tank venting valve is recorded. In order to enable a reliable function check of the tank venting valve even in the case of very small and/or time-shifted amplitudes of the quantity to be monitored, it is proposed, according to the invention, that the first derivative of the time characteristic of the quantity be evaluated.Type: ApplicationFiled: December 18, 2009Publication date: July 1, 2010Applicant: Audi AGInventors: Oliver Grunwald, Siegfried Meixner, Peter Enders
