Patent number: 8256282Abstract: The critical desorption pressure is determined by pumping out an area within a well bore. As the pressure in that area is decreased, formation fluid from the surrounding rock matrix is drawn into the area. As the local pressure is decreased further, gaseous bubbles within the formation fluid will begin to form. The formation fluid is observed, and the formation of the gaseous bubbles is detected. The critical desorption pressure is determined based upon the presence of gas within the formation fluid. The concentration of gas within the formation fluid can then be determined based on the determination of the critical desorption pressure.Type: GrantFiled: July 15, 2008Date of Patent: September 4, 2012Assignee: Schlumberger Technology CorporationInventor: Greg Schlachter

Patent number: 8256287Abstract: A system and device that provides for the retention of a sensor shield for a sensor such as a microphone, hydrometer, chemical sensor, or other detector. This invention provides for the quick attachment and release of a reduced visibility and reduced bulk shield retention assembly. In a battlefield environment, a smaller profile sensor shield presents less visibility as a prospective target of interest to enemy forces. Also, the sensor shield may be readily replaced without the use of any tools. The snap-lock feature provides a positive means for holding, for example, a windscreen in its respective position, requiring reasonable, but yet not objectionable force to install and remove the windscreen from the sensor's mounting shaft. Furthermore, the snap-lock feature, when engaged, may provide positive location of the sensor shield's sweet spot by maintaining a slight air space between the sensor shield and the sensor, and thereby precluding direct physical contact.Type: GrantFiled: April 15, 2010Date of Patent: September 4, 2012Assignee: AAI CorporationInventor: Michael J.

Patent number: 8256291Abstract: An acceleration-triggered or shock-triggered, smart, tunable MEMS switch that may function as both a classic accelerometer and an acceleration threshold detector. A parallel element MEMS device has a stationary and a movable element forming a capacitor.

Patent number: 8256307Abstract: Testing of engine particulate matter production during a transient is made more accurate by selecting an appropriate sized opening for a test probe of the sampling system located in the exhaust line upstream from a particulate trap.

The flow opening into the test probe of the sampling system behaves relative unrestricted when pressure differentials at the test probe location are relatively low, such as during steady state operating conditions, but restricts flow into the sampling system when pressure differentials are relatively high, such as at a pressure during a transient event.Type: GrantFiled: October 24, 2008Date of Patent: September 4, 2012Assignee: Caterpillar Inc.Inventors: Russell R.

Patent number: 8256321Abstract: A displacement member can be displaced in a direction substantially perpendicular to a moving direction of a translation member that is held on a base member so as to reciprocatingly move thereon linearly, and an elastic mechanism secured to the base member accumulates and releases elastic energy in accordance with the distance to the displacement member. Protruding members of the translation member are pressed against a transmission member by generated force provided by the energy release from the elastic mechanism; thus, a distance adjusting operation between coupling mechanisms coupling the transmission member and the displacement member is controlled by a control device so that the relative position and relative angle between the displacement member and the transmission member are changed.Type: GrantFiled: December 8, 2010Date of Patent: September 4, 2012Assignee: Panasonic CorporationInventor: Katsuhiko Asai

Patent number: 8256324Abstract: A transmission shifter includes a shift lever, and a knob with attachment clip that mechanically locks the knob atop the lever with a single assembly motion. The clip is located inside a hole in the select knob, and the lever includes a notch near its top. The clip is positioned to flex to facilitate assembly as the lever is inserted into the hole, but then unflex to engage the notch and lock the knob to the lever. To remove the knob from the lever, a removal tool is used to depress the clip, pushing it out of the way and allowing the select knob to be pulled off the lever. The illustrated shifters include a mechanically-actuated pawl actuator system and an electrically-actuated pawl actuator system.Type: GrantFiled: July 1, 2008Date of Patent: September 4, 2012Assignee: GHSP, Inc.Inventors: Robert J. Laming, Scott Ebenstein

Patent number: 8256325Abstract: A wheel is for use in manually turning a shaft on rolling stock, such as for a handbrake. The wheel has a hub and a rim. The hub is made of a first material and has an opening that is structured and arranged to receive the shaft. The opening has a rotational axis. The hub has an exterior around the rotational axis, with the hub having drive surfaces relative to the rotational axis. The rim is coupled to the hub so as to engage the drive surfaces. The drive surfaces include flat surfaces and corners of a tube portion of the hub, a radially extending plate with holes therethrough and teeth in an outer edge and gussets coupled between the tube portion and the plate. The rim has an outer periphery structured and arranged to be gripped by a human hand for rotating the wheel. The rim is made of a second material that is softer than the first material.Type: GrantFiled: January 26, 2006Date of Patent: September 4, 2012Inventors: Michael P. Fritzel, Steve Rains

Patent number: 8256326Abstract: A control unit that is not subjected to any external force except its own weight until completion of assembly, and is easily mounted to an automatic transmission. A connector facing an inside connector provided inside an automatic transmission is provided at a lower end of a unit main body, and another connecter exposed to the outside of the automatic transmission is provided at an upper end of the unit main body. The unit main body includes a control device such as a microcomputer for controlling the automatic transmission. The unit main body is guided by a moving-side guide portion formed in a lower part thereof and protrusions provided as a fixing-side guide portion, thereby connecting the lower end connecter to the connector. The automatic transmission and the unit main body are sealed by a flange and a packing of a sealing mechanism portion. The flange covers from above a through hole for inserting the unit main body of the automatic transmission therein.Type: GrantFiled: November 22, 2007Date of Patent: September 4, 2012Assignee: Aisin AW Co., Ltd.Inventors: Naotaka Murakami, Kenji Suzuki, Jun Takamatsu

Patent number: 8256328Abstract: A power transmission device for a four-wheel drive vehicle includes an input shaft adapted to be driven by a power source. A first output shaft is rotatable about a first axis and adapted to transmit torque to a first driveline. A second output shaft is adapted to transmit torque to a second driveline and is rotatable about a second axis. The first and second axes diverge from one another. A transfer unit includes a drive member rotatably supported on the first output shaft and a driven member coupled to the second output shaft. A joint is positioned within a cavity formed in the driven member and drivingly interconnects the driven member and the second output shaft. The driven member includes first and second portions separable from and re-mountable to each other to allow service to the joint.Type: GrantFiled: June 10, 2009Date of Patent: September 4, 2012Assignee: Magna Powertrain of America, Inc.Inventors: Carl F.
