Patent number: 8973853Abstract: In a process for producing a particulate polysaccharide derivative by dry-grinding a moist polysaccharide derivative, one or more of the properties selected from median diameter, median length, bulk density and dissolution rate is controlled by controlling the temperature of the polysaccharide derivative prior to dry-grinding. Advantageously one or more of the properties selected from median diameter, median length, bulk density and dissolution rate of the particles after dry-grinding is adjusted to a first value by a first temperature of the polysaccharide derivative prior to dry-grinding and is adjusted to a second value by a second temperature.Type: GrantFiled: July 28, 2010Date of Patent: March 10, 2015Assignee: Dow Global Technologies LLCInventors: Peter E.

Publication number: 20150066265Abstract: Methods and systems are provided for dynamically allocating engine torque and motor torque in a hybrid vehicle to meet operator torque demand. The allocation is adjusted by constraining the maximum engine torque allowable under selected conditions to provide a better trade-off between performance and fuel economy. A maximum engine torque that provides best fuel economy is learned during engine operation at different engine speed-load conditions based on a deviation in spark retard torque ratio from a threshold ratio as spark timing is moved to MBT.Type: ApplicationFiled: September 4, 2013Publication date: March 5, 2015Applicant: Ford Global Technologies, LLCInventors: Douglas Raymond Martin, Ted Haladyna, Kenneth James Miller

Publication number: 20150059700Abstract: A method for controlling an engine supplied with multiple fuels in which the vapor purge flow into the engine from multiple vapor storage devices each coupled to a respective, but equal number of multiple fuel tanks controlled to have the same proportion of total vapors purged as a proportion of liquid fuel delivered to the engine from said respective one of the said multiple fuel tanks. The method includes increasing the delivery of fuel from one of the multiple fuel tanks containing fuel with the highest-octane rating of all the fuel tanks when the vapor storage canister coupled to the fuel tank with the highest-octane fuel is not being purged of its fuel vapors. Additionally, the method further comprises a feedback control responsive to an exhaust gas oxygen sensor to adjust said fuel delivered from said multiple fuel tanks to the engine to maintain engine air-fuel ratio around stoichiometry.Type: ApplicationFiled: September 5, 2013Publication date: March 5, 2015Applicant: Ford Global Technologies, LLCInventors: Thomas G.

Publication number: 20150061708Abstract: Systems, apparatus, and methods detect a current sensor error in an FOC electric machine system. A voltage command is monitored to detect the presence of an ac component can indicate that an error has occurred at a current sensor. By way of example, a sensor fault detection module can be configured to determine the deviation between an actual voltage command and an ideal voltage command to provide a complex deviation vector. By transforming the deviation vector to a reference frame rotating at the fundamental frequency of the command voltage, a dc component of the positive and negative sequences can be filtered, and their amplitudes determined. Error detection can be based on the total amplitude of the fundamental component, determined by positive and negative component amplitudes. The invention enables an FOC system to operate with two current sensors, rather than three, and provides a dedicated fault diagnostic for a current sensor.Type: ApplicationFiled: August 27, 2013Publication date: March 5, 2015Applicant: Ford Global Technologies, LLCInventors: Chang-jiang Wang, Michael Degner, Rimma Isayeva, Liwen Xu, Daniel R.
