| 20100078305 | Scrubber for fluid coker unit - Fouling in the scrubber section of a fluid coker unit is reduced by providing baffles to improve the uniformity of the gas flow profile in the scrubber by reducing the gas velocity of the cyclone outlet gases in the scrubber section of the unit. These baffles are located with the objective of reducing the rotational component of the gas flow in the scrubber created by the alignment of the gas outlets of the cyclones. The baffles are preferably located in the shed section of the scrubber and comprise upstanding perforated plates located at the periphery of the scrubber section to disrupt high velocity gas jets in the region of the interior wall of the scrubber. | 04-01-2010 |

| 20080313914 | VEHICULAR CRASH TEST MEASURING SYSTEM - A fixture for positioning an ATD relative to a vehicle includes a housing attached to the vehicle having a first end and a second end. A locator is mounted on the housing and is movable along the housing between the first end and the second end to identify a position of the ATD relative to the housing. A target is disposed on the ATD and is spaced apart from the housing for alignment with the locator. A first measurement device outputs an angle of the housing that identifies an angular position of the target relative to a plane extending through the first end of the housing. | 12-25-2008 |

| 20110005839 | Retention Means for a Seal Boot Used in a Universal Joint in a Downhole Motor Driveshaft Assembly - A driveshaft assembly for a downhole motor comprises a housing and a driveshaft rotatably disposed within the housing. The driveshaft has a central axis and a first end. Further, the driveshaft assembly comprises a driveshaft adapter having a first end coupled to the first end of the driveshaft with a universal joint. The first end of the driveshaft adapter includes a counterbore. The first end of the driveshaft and the universal joint are disposed in the counterbore. Still further, the driveshaft assembly comprises an end cap disposed about the driveshaft and coaxially coupled to the adapter. Moreover, the driveshaft assembly comprises a seal boot disposed about the driveshaft and adapted to restrict fluid flow through a annular gap positioned between the driveshaft and the end cap. The driveshaft assembly also comprises a locking assembly adapted to restrict the end cap from moving axially relative to the adapter. | 01-13-2011 |
