Abstract: A method of assembling a bore repair assembly for use with a wind turbine. The wind turbine includes a gearbox assembly that defines a first bearing bore and a second bearing bore coaxially aligned with the first bearing bore. The method includes coupling a first support assembly with respect to the second bearing bore. A boring bar is positioned coaxially within the first bearing bore and through the second bearing bore. The boring bar is rotatably coupled to the first support assembly. A boring bar drive assembly is coupled to the boring bar for rotating the boring bar about a central bearing axis.

Abstract: Described is an anti-vibratory handle for installation on a reciprocating tool supplied with a pressurized fluid and producing vibrations in the direction of an axis of reciprocation of the tool. The anti-vibratory handle comprises a stationary portion mounted to a body of the tool, a mobile portion comprising a hand-grip member and an articulation between the stationary and mobile portions. This articulation comprises a pivot assembly interconnecting the stationary and mobile portions, the pivot assembly defines a pivot axis substantially perpendicular to the tool reciprocation axis, and the hand-grip member of the mobile portion is spaced apart from both the pivot axis and the tool reciprocation axis. The articulation also comprises a resilient vibration-damping assembly interposed between the stationary and mobile portions to avoid transmission of vibrations through the articulation.

Abstract: A method and device for removing pollution from polluted water, consisting of a rod on which are mounted an array of spaced magnesium plates and an array of spaced copper plates. The copper plates are in contact with the magnesium plates. Polluted water passing through the plates results in precipitates of the pollutants which can be mechanically removed.
