    Abstract: A method for maintaining pressure in a wellbore during drilling operations includes the steps of providing fluid from a reservoir through a drill string, circulating the fluid from the drill string to an annulus between the drill string and the wellbore, isolating pressure in the annulus, measuring pressure in the annulus, calculating a set point backpressure, applying back pressure to the annulus based on the set point back pressure, diverting fluid from the annulus to a controllable choke, controllably bleeding off pressurized fluid from the annulus, separating solids from the fluid, and directing the fluid back to the reservoir. An apparatus for maintaining pressure in a wellbore during drilling operations includes an adjustable choke for controllably bleeding off pressurized fluid from the wellbore annulus, a backpressure pump for applying a calculated set point backpressure, and a processor for controlling the adjustable choke and backpressure pump.

    Abstract: There is provided a sheet driver for use in a medicament dispenser including a medicament carrier having a plurality of pockets for containing medicament wherein said pockets are spaced along the length of and defined between first and second sheets secured to each other and separable by drivable pulling action, the sheet driver comprising a base; ascending from the base, a shaft defining a rotational axis; on the base, a drive surface for receipt of drive to rotate the base about the rotational axis; about the shaft, a torsion spring defining first and second spring legs; mounting about the shaft and the torsion spring for rotation about the rotational axis, a hub defining a hub surface for receipt of a sheet of the medicament carrier. A first leg receiver of the base receives the first spring leg of the torsion spring and a second leg receiver of the hub receives the second spring leg of the torsion spring such that relative rotation of the base and the hub results in tensioning of the torsion spring.

    Abstract: An electronically-controlled viscous fan drive in which the output drive to the fan is electronically controlled by the movement of viscous fluid from a fluid reservoir and into the operating and working chamber of the coupling during normal operation. A radially balanced valve disk coupled to a spring controls the relative movement of viscous fluid from a fluid reservoir to the working chamber by sealingly engaging and disengaging a fill hole fluidically coupling the fluid reservoir to the working chamber. The clutch plate and cover and body, along with the features defined between the clutch plate and cover and body are cast to the desired size and shape, therein allowing easier and more precise manufacturing and more cost effective manufacturing as compared with traditional designs that are stamped and having machined-in features.

    Abstract: Methods and apparatus for rotating a stripper assembly in use with a rotating drilling head. A drive system is disposed external to the rotating drilling head and generates rotational motion to match the rotation of a drillstring running through the rotating drilling head. A connection transfers rotational motion from the drive system to the stripper assembly. In one embodiment, the drive system comprises a housing disposed about the drillstring and a one or more contact members connected to said housing and operable to contact the drillstring. One or more biasing members urge the contact members into contact with the drillstring so as to transfer rotational motion from the drillstring to the housing.
