Abstract: A rotor system for an aircraft includes an open rotor assembly comprising an open rotor assembly comprising a plurality of rotor blades connected to a rotor mast, wherein the rotor assembly is tiltable relative to a wing of the aircraft between a first position corresponding to an airplane mode of the aircraft and a second position corresponding to a helicopter mode of the aircraft; and a drive system for providing rotational energy to the open rotor assembly via the rotor mast. The drive system includes at least one electric motor for generating rotational energy to a motor shaft; and a gearbox connected to receive rotational energy from the at least one electric motor via the motor shaft and to provide rotational energy to the rotor mast via a rotor shaft, wherein the at least one electric motor is fixed relative to the wing of the aircraft.

Abstract: A batcher unit for a book block finishing machine can include at least one receiving member to receive a plurality of sheets and stack the plurality of sheets into a book block having a binding face lying in a binding plane. The batcher unit can also include at least one adhesive applicator to apply adhesive to the at least one binding face of the book block to bind together the edges of plurality of sheets. The adhesive applicator can be moveable in relative to the binding plane and can direct a stream of adhesive toward the binding plane along a first adhesive axis when the adhesive applicator is in a first position, and along a second adhesive axis when the adhesive applicator is in a second position. The first and second adhesive axes can intersect the binding plane at respective angles.

Abstract: A book block finishing machine includes a forming unit to receive a printed web and a sheeting unit downstream from the forming unit to receive the web and to separate the web into at least one plurality of sheets. The machine also includes a batcher unit that includes at least one hopper to receive and stack each plurality of sheets to form at least one book block. The batcher unit also includes at least one adhesive applicator. Each adhesive applicator is operable to apply adhesive to at least one edge of each book block to bind together the plurality of sheets forming each book block.

Abstract: An apparatus for conveying a plurality of sheets into a receiving member includes receiving member and a conveyor for conveying a plurality of sheets into the receiving member so that the sheets are stacked one upon another to form a book block. The conveyor can have a downstream end that is moveable relative to the stack of sheets in the receiving member. The apparatus can also include an actuator connected to the conveyor that is operable to move the downstream end of the conveyor relative to the stack of sheets in the receiving member.

Abstract: A batcher unit for a book block finishing machine can include a plurality of receiving members. Each receiving member can be operable to receive and stack a corresponding plurality of sheets. The batcher unit can also include a plurality of adhesive applicators. At least one adhesive applicator can be associated with each receiving member. Each adhesive applicator can be displaceable relative to its associated receiving member to apply adhesive to at least one edge of the stack of sheets in the receiving member to form a book block, and each adhesive applicator can be operable to be independently displaceable with respect to the other adhesive applicators.

Abstract: The present invention is directed to a sheet feeding apparatus and method. In particular this invention comprises a sheet feeding apparatus having a first conveyance member, a second conveyance member, and a sheet bending member. The first conveyance member conveys a sheet from a source of sheets at the first speed. The second conveyance member is positioned near the first conveyance member, and conveys the sheets away from the first conveyance member at a second speed that is less than the first speed of the first conveyance member. The sheet bending member is positioned to engage the sheet as the sheet moves from the first conveyance member to the second conveyance member. The sheet bending member engages the sheet to produce a gap between the tail end of the sheet and the second conveyance member. The lead edge of the next adjacent sheet from the first conveyance member is then fed into the gap.
