Abstract: A power tool includes a handle (38) which allows the user to operate the tool via a trigger (44). The handle is arranged relative to the body (36) of the tool such that the user may operate the tool in a plurality of positions relative to a workpiece. The handle (38) is positioned such that a force applied thereto along a line of action allows operation of the tool along that line of action regardless of in which of the plurality of positions the power tool is held relative to the workpiece. Furthermore, the handle (38) is configured to be accessible from more than one side thereof each accessible side corresponding to a given one of the plurality of different positions.

Abstract: A coupling mechanism for a power tool is provided on one portion of the tool and comprises a generally cylindrical projection with a side wall having a radial recess extending part-circumferentially along the side wall. A further projection is formed on the side wall which extends in both directions parallel to the axis of the cylindrical projection and in a direction radially outward from the side wall as well.

Abstract: A fluid-film foil bearing has a resilient bearing insert assembly disposed between a rotatable and a stationary member. The insert assembly comprises a plurality of resilient corrugated spring pad supports separated from each other to provide a series of spaces and a compliant, unitary foil mounted on the pad supports, the foil having a plurality of perforations aligned across its entire width and over the spaces which are operative under dynamic conditions both to initiate foil deflection and to cause uniform replenishment of fluid lost through side leakage.
