Abstract: A collapsible steering column assembly includes a shroud comprising an outer tube that supports a steering wheel through a bearing and an inner tube that is fixed to a part of the vehicle, the column assembly being able to collapse telescopically by the outer tube moving over the inner tube, the assembly further including an energy absorbing strap that is fixed to the inner tube and a plough which is fixed to the outer tube, whereby in use the assembly is so arranged that upon a telescopic collapse the relative movement between the inner tube and the outer tube forces a part of the plough through the strap to progressively peel away a part of the strap from the remainder of the strap.

Abstract: A roller for use in devices configured to comminute material has a wear surface. The wear surface comprises inserts that are spaced apart differently to provide a desired wear characteristic in the wear surface. In one embodiment, some inserts may also have diameters or widths that are smaller than other inserts. For example, columns of inserts adjacent an end of the roller may have diameters that are smaller or larger than inserts in columns located near the center of the roller or otherwise positioned between the two ends of the roller. As another example, a middle portion of the wear surface may have inserts that include inserts of a larger or smaller diameter than inserts adjacent the ends of the wear surface.
