Abstract: A system for applying a tensile load to a component includes a failsafe structure, a principal part of which is configured to act in compression during application of the load to the component, but which includes a mechanical fuse configured to act in tension during application of the load to the component. The mechanical fuse being configured to fracture upon the application of a predetermined tensile force thereto.

Abstract: A rotating arrangement comprising a rotating assembly mounted on an associated bearing defining a geometric axis of rotation for the rotating assembly, the rotating assembly comprising: i) a first part mounted on the bearing for rotation relative to the bearing about the geometric axis; ii) a second part engaged with the first part for independent relative angular adjustment about a second axis, eccentric to the geometric axis, and iii) a third part engaged with the second part for independent relative angular adjustment about a third axis, eccentric to the second axis; whereby said relative angular adjustment about one or both of the second and third axes can be used to adjust the position of the centre of mass of the rotating assembly to be substantially co-incident with the geometric axis of rotation.
