20100280237 | PREPARATION OF METAL MESOPORPHYRIN COMPOUNDS - A method of preparing metal mesoporphyrin halide compounds is described. The metal mesoporphyrin halide compound may be formed by forming a novel mesoporphyrin IX intermediate compound and then converting the mesoporphyrin IX intermediate to the metal mesoporphyrin halide through metal insertion. The novel intermediate compound may be formed by a catalytic hydrogenation of hemin in acid and subsequent recovery. | 11-04-2010 |

20090099740 | Concept for using software/electronics to calibrate the control system for an automatic transmission - A software calibration strategy for calibrating solenoid controlled valves and valve systems in an automatic transmission. The strategy includes identifying a characteristic equation for the valve or valve system that is a mathematical relationship between a current applied to the solenoid and the pressure at the output of the valve or valve system. The valve or valve system is coupled to a test stand that depicts the operation of the valve or valve system in the transmission. Current signals are applied to the valve or valve system, and the output pressures are measured to determine coefficients in the equation using a curve fitting function. The coefficients are then stored in a control unit. | 04-16-2009 |

20090071545 | AUTOMATIC TRANSMISSION HAVING HYDRAULIC VALVES WITH FLOW FORCE COMPENSATION - An automatic transmission having at least one hydraulic valve with flow force compensation. The hydraulic valve includes a valve body having a valve bore and at least one inlet and at least one outlet adapted to provide fluid communication with a source of pressurized hydraulic fluid and a return to the source of pressure. A valve member is slidingly disposed within the valve body that includes at least one valve element having an outer diameter and a metering face. The metering face is adapted to control the flow of pressurized hydraulic fluid between the inlet and the outlet of the valve body. The metering face includes a flow force compensating annular void disposed adjacent to the outer diameter that is defined by a lead angle α measured between the outer surface and a line intersecting the outer surface and tangential to the annular void. | 03-19-2009 |

20120317807 | METHOD OF SETTING LASH IN A CAM PHASER - A method of setting lash in a cam phaser includes rotating a stator having a lobe in a first direction so that the lobe contacts a motion limiter pin disposed within a first hole in a rotor, causing the compression of a spring until a motion limiter lock pin enters a groove on the motion limiter pin and contacts a wall at one end of the groove. The rotor is then rotated in conjunction with the stator in the first direction until a rotor locking pin that is disposed within a second hole in the rotor engages a lock pin seat on a cover at one end of the seat. The rotor is then held in place while rotating the stator in a second direction so that there is a gap between the wall at one end of the groove and the motion limiter locking pin. | 12-20-2012 |
20120318220 | CAM PHASER LOCKING SYSTEMS - A motion limiter system for a cam phaser includes a retractable motion limiter pin that is selectively extendable from a rotor in a cam phaser to contact a lobe on a stator to provide a positive stop for the rotor prior to engagement of a locking pin. Alternatively, the cam phaser may include two pins that are selectively extendable from opposite openings in a hole in the rotor to engage seats that are slightly offset from one another. | 12-20-2012 |
20150019105 | VARIABLE CAM PHASER - A cam phaser includes a rotor, a stator, and a cover. The rotor defines a first hole and a second hole and can rotate relative to the stator between a first intermediate position and a second intermediate position. The cover is mounted on the stator and defines a first lock pin seat and a second lock pin seat. The cam phaser includes a first lock pin and a second lock pin. The first lock pin can move along the first hole and into the first lock pin seat to lock the rotor relative to the stator at the first intermediate position. The second lock pin can move along the second hole and into the second lock pin seat to lock the rotor relative to the stator at the second intermediate position. | 01-15-2015 |
