| 20090165273 | Gas turbine rotor assembly method - Methods of assembling a rotor assembly of a gas turbine engine having a plurality of components. The method comprises, in one aspect, determining a static unbalance force of each component using the mass and the center of mass location, and determining an optimum assembly arrangement minimizing static unbalance forces. Optimal component stacking positions, among other things, may then be established. | 07-02-2009 |

| 20100232920 | COUPLER FOR EARTH MOVING OR MATERIALS HANDLING MACHINE - A coupler is configured to couple an implement to an earth moving or materials handling machine. The coupler includes a locking member for locking a pin of an implement into a coupler in the recess. The locking member is driven by a hydraulic arrangement, with the hydraulic cylinder body being formed integrally with either the coupler body or the locking member. The coupler may be adapted to accommodate a range of implement pin spacings and/or diameters, so that the coupler can be used with different implements and in particular with different makes of implement. | 09-16-2010 |

| 20100058622 | TOOTH BAR MOUNTING - A mounting for a tooth bar to a mounting surface of a thumb sub-assembly, the mounting including one or more inwardly narrowing slots located adjacent the mounting surface and into which a part of a mounting portion of the tooth bar can be wedgingly engaged, there being fixing means for fixing the tooth bar into engagement with the mounting surface following the mounting portion being wedgingly engaged. | 03-11-2010 |
| 20100232919 | PIVOTING IMPLEMENTS AND ADJUSTMENT ARRANGEMENTS FOR EARTH MOVING OR MATERIALS HANDLING MACHINES - An implement pivots with respect to an earth moving or materials handling machine to which the implement is attached. The implement may be a bucket adapted to pivot laterally with respect to an excavator or other machine to which the bucket is attached. An adjustment arrangement includes a linear actuator which operates along a substantially fixed axis to drive the pivoting movement. The linear actuator may drive a rack which engages with a pinion to cause pivoting movement. | 09-16-2010 |
