| 20080196889 | Reverse Circulation Cementing Valve - A method for reverse cementing may include providing a valve having a sliding sleeve, an outer sleeve situated about at least a portion of the sliding sleeve and connected to a casing string, and a spring configured to position the valve in an open position. The method may also include: running the casing string and valve into a well bore while the valve is in an open position; reverse cementing, while the valve is in an open position; and closing the valve after reverse cementing by allowing the valve to contact the well bore. | 08-21-2008 |
| 20090166044 | Selectively Activated Float Equipment - A valve for a well pipe, the valve having the following parts: a valve collar connectable to the well pipe; an index piston coaxially positioned within the valve collar for longitudinal translation within the valve collar between closed, flow-open, and locked-open configurations; a detent in the index piston, wherein the detent restricts fluid flow in a circulation direction through a flow path through the index piston; a spring that biases the index piston toward the closed and locked-open configurations; and a plug of the valve collar that mechanically communicates with the index piston to be in corresponding closed, flow-open, and locked-open configurations. | 07-02-2009 |

| 20120067530 | Idle End Assembly - The present invention relates to a roller blind idle end assembly for roller blinds comprising a splined bush, a support bearing and an end pin, wherein the splined bush is supported by the support bearing and rotatable relative thereto in use; the end pin projects from the support bearing and is slidably coupled thereto such that the end pin is adapted to move axially relative to the support bearing and projects therefrom to engage with a receiving element of a mounting bracket; and wherein the end pin is rotationally fixed relative to the support bearing. This assembly reduces wear between an idle end pin and an idle end bracket and the likelihood of failure of the blind. | 03-22-2012 |

| 20090095351 | PIPELINE ADDITIVE CONTROL DEVICE AND METHOD - A pipeline additive injection system including: an injection pump for injecting an amount of additive into a pipeline; a battery for powering the injection pump; system sensors to monitor system conditions; and a controller for retrieving system data from the system sensors and for controlling operation of the injection pump based on the system data to achieve additive injection compensation. | 04-16-2009 |
| 20090248326 | VIBRATION SENSOR - A vibration sensor includes a housing, a high G accelerometer installed in the housing to measure vibratory accelerations communicated to the housing; a low G accelerometer installed in the housing to measure vibratory accelerations communicated to the housing; and a processor installed within the housing to receive data from the high G accelerometer and the low G accelerometer. A method for using the vibration sensor includes employing the low G and the high G acceleration data. Another vibration sensor includes intrinsically safe buttons. | 10-01-2009 |
