Abstract: A clamp assembly device for connecting a rotating control device bearing assembly to a main body of a rotating control device. The device includes clamp members configured to retain the bearing assembly in place on the main body, a clamp actuator for driving clamping and unclamping of the clamp members and a lock pin controlled by a lock pin actuator. The lock pin actuator is configured to lock and unlock the clamp assembly device by moving the pin between locked and unlocked positions along an axis substantially parallel with the axis of rotation of the bearing assembly.

Abstract: A sealing element for a rotating control device includes an elastomeric body having a central bore for sealing against a pipe passing therethrough. The elastomeric body has an upper portion which is internally reinforced with a frame and a lower portion formed with a plurality of protrusions. The radial protrusions provide columnar support to the lower portion permitting the lower portion to resist centrifugal and frictional forces against the lower portion during drilling and other operations. The sealing element may be used to form an assembly with reusable parts for connecting the sealing element to a mandrel of a rotating control device.

Abstract: A scale system includes a frame for placement over a toilet and a net to catch waste, for example from bowel movements. A scale is connected to the frame to register a change in tension experienced by the frame as waste is received by the net. The resulting weight measurement may be shown on a digital display. Once the user is done, a release lever on the frame may be triggered to release the net and waste into the toilet.

Abstract: A method of automatically carrying IC-chips, on a planar array of vacuum nozzles, to a variable target in a chip tester uses a set of laser distance sensors to align the vacuum nozzles with the target. Alignment occurs when certain combinations of distance and distance changes are sensed.

Abstract: A pipe gripping device is taught which is useful for moving pipe into and/or out of a well. The pipe gripping device includes a first set of slips for holding a pipe in a pipe light condition and a second set of slips for holding a pipe in a pipe heavy condition. The second set of slips are actuatable independently from the first set of slips. The pipe gripping device can include a slip moving system which prevents the slip carrier blocks from being driven outwardly against the housing, to thereby prevent the carrier blocks from locking, by being driven against the housing.

Abstract: A system for recognizing objects is comprised of: 1) a camera that has a lens which is uncovered; 2) a housing which encloses the camera, and has a window for the lens; 3) a rotating means, which is inside of the housing and which carries the camera, for receiving electronic control signals and rotating the camera at different angles in response thereto; and, 4) a control means for generating the electronic control signals such that the rotating means selectively points the camera lens -a) through the window at any one of several predetermined angles, and b) inside of the housing at the surface for calibrating the camera. With this system, the objects that are recognized can be human faces at different heights relative to the window in the housing. By pointing the camera lens inside of the housing, the lens is protected from damage even though it is not covered; and a calibration surface inside of the housing enables the camera to be calibrated while the lens is protected.

Abstract: A hydraulic system and method are provided for supplying high pressure hydraulic fluid to a cylinder for operating a ram, e.g. a shearing and/or shut-off ram for a blowout preventer. It comprises means for supplying high pressure hydraulic fluid to the cylinder, said hydraulic fluid supply means comprising first and second storage means for storing hydraulic fluid under pressure, first conduit means for supplying hydraulic fluid under pressure from said first storage means to the cylinder, a pressure sensing device for determining the back pressure in said first conduit means, second conduit means for supplying hydraulic fluid under pressure from said second storage means to the cylinder and valve means for automatically opening said second conduit means when the back pressure in the first conduit means reaches a predetermined amount.
