| 20080272609 | Claw for a Container Transporting System - A clamp grip for a container transport system including rare earth permanent magnets encapsulated in non-magnetic material such as high quality steel. Flexible positioning of the magnets allow for adapting to varied design specifications. A rotatable control cam or cams may be used to adjust grip arms between a grip and a release position. Air gap distances between permanent magnets may be designed to maximize repelling force to assist in the functioning of clamp grip mechanism. | 11-06-2008 |

| 20120326459 | EXTENDED RANGE SINGLE-JOINT ELEVATOR - An oilfield elevator is disclosed and has first and second body halves pivotally-coupled at a hinge and moveable between an open position and a closed position to receive and move a tubular segment. Slips are slidably received within corresponding tapered slots in the elevator and are configured to translate vertically within the tapered slots and, at the same time, radially so as to be able to capture a wider range of tubular having varied outside diameters. Tension handles are pivotally-coupled to the first and second body halves and moveable between locked and unlocked positions. Locking the tension handles engages the slips via biasing members, and forces the slips into radial contact with the tubular segment. Unlocking the tension handles releases the biasing members. | 12-27-2012 |
