Abstract: A self-aligning dynamic hinge sleeve for attachment to a pitch hinge in a position that places the hinge sleeve in contact with a pitch bearing. The hinge sleeve is comprised of an inner race, a middle race and an outer race, wherein the middle race is an elastomeric material, or another soft material, that bonds the inner and outer races together and allows the inner race and outer race to rotate with respect to each other. As the pitch hinge transmits forces and moment to a pitch shaft, the dynamic hinge sleeve aligns with a pitch bearing secured onto the pitch shaft. This results in a self-aligning pitch bearing rotor that significantly reduces the level of peak that loads upon a bearing and thereby permits the use of self-lubricating bearings in a rotor.

Abstract: In the manufacture of roof tiles comprising extruding a continuous shaped ribbon of tile forming material onto a succession of pallets, and cutting the ribbon where pallets adjoin to form individual green state tiles on pallets, there is performed the step of causing a cutting tool to engage with the upper surface of the ribbon only for part of the length of each pallet whereby a recess is formed in the upper surface of each tile. In a particular embodiment the recess is a channel cut in the tile at a location immediately downstream of the extruding step. The recess is also subsequently smoothed by applying a smoothing roll thereto.

Abstract: Process for forming coated pitch prills by mixing pitch prills with finely divided carbonaceous material and agitating the prills and carbonaceous material until a layer of carbonaceous material adherently bonded to the pitch prill is formed. Preferably the pitch prill is a substantially spherical particle having an average diameter between about 1 and about 5 millimeters. The finely divided carbonaceous material is preferably carbon black.
