Abstract: A gearing assembly for a vehicle drivetrain. The assembly includes a first shaft rotating about a first shaft axis; a second shaft with a second shaft axis parallel to the first shaft axis; a first freewheel clutch gear mounted to the first shaft; a second gear mounted to the first shaft; a third freewheel clutch gear mounted to the second shaft and engaged with the second gear; and a fourth gear mounted to the second shaft and engaged with the first gear. When the first shaft rotational speed is greater than the second shaft rotational speed, the first shaft drives the second shaft via the second and third gear, the first gear being overrun; and when the second shaft rotational speed is greater than the first shaft rotational speed, the second shaft drives the first shaft via the fourth and first gear, the third gear being overrun.

Abstract: A power pack for a vehicle selected from a group of different vehicles is disclosed. The power pack includes an internal combustion engine and a continuously variable transmission (CVT) operatively connected to the engine. The CVT includes: a drive pulley operatively connected to a crankshaft of the engine, the drive pulley being rotatable about a drive pulley axis; a driven pulley rotatable about a driven pulley axis; a belt connecting the drive pulley to the driven pulley; and a housing at least partly enclosing the drive pulley, the driven pulley and the belt. The power pack also includes a sub-transmission selected from a group of different sub-transmissions depending on the selected vehicle. The selected sub-transmission is mounted to the housing of the CVT. The housing of the CVT is configured to mount any sub-transmission of the group of different sub-transmissions. A method for assembling a power pack is also provided.

Abstract: It is provided a WPC extrusion profile comprising a WPC material, in which plant fibers are embedded in a plastic matrix, wherein the WPC material has a content of naturally growing plant fibers of between 30 and 75 wt-%, and the WPC extrusion profile includes at least one foam-filled hollow chamber. The at least one hollow chamber of the WPC extrusion profile is completely filled up with a foam, in particular a closed-pore foam. The foam includes or consists of a plastic material of the same type of plastic as the matrix of the WPC material. The foaming is effected by using a physically acting blowing agent, in particular CO2, wherein the density of the foam is less than 0.4 g/cm3 and the average cell size of the foam has a mean diameter of less than 0.4 mm.

Abstract: The invention relates to a process for producing spongiosa bone ceramic. Between the demineralization of the bone material and the sintering to a ceramic, an extractive washing operation is carried out using demineralized water, by means of which calcium oxide components are removed from the demineralized bone matrix.
