Abstract: An integrated operational ground mobility and support system (10) that includes an aircraft (12) having one or more service openings on a side of the aircraft (12). The integrated support system (10) may have an airport interface terminal docking port (14) that has a ground support service sub-system. The docking port (14) mates with the aircraft (12) at the service openings and has multiple service levels. The ground support service sub-system provides services to the aircraft (12) through the service openings and on the service levels. The integrated support system (10) may have in addition to or in replacement of the interface terminal docking port an aircraft loader/unloader. The loader/unloader has ground support service sub-systems and mates with the aircraft (12) at one or more of the service openings. The service sub-systems of the loader/unloader include a passenger ingress/egress system (62) and provide services to the aircraft (12).

Abstract: A work transfer assembly including a transfer car movable along a path for transporting a workpiece carrier between separate processing stations positioned along the path. The car includes a push-pull chain made up of a plurality of links with one of the links defined by a pair of spaced support plates having upwardly extending support flanges interconnected by a shaft which rotatably supports a coupler member. The coupler member is a single unitary member having a pair of side plates interconnected by an abutment plate below which is an L-shaped plate defining a hook. The coupler member is rotatably supported for movement between a hook position with the hook in position for hooking a tray for removing the tray from a station and an abutment position with the abutment plate in position for abutting the tray for pushing the tray into the station.
