Abstract: An automated transport system for use in a material handling system. The automated transport system employs a distributed control system including a top level controller (transport controller), a plurality of second-level controllers (control logic computers) and a plurality of third-level controllers (intelligent drivers). The transport controller (TC) receives material commands from a conventional material control system (MCS). The TC breaks the command into sub-commands directing selected control logic computers (CLCs) to acquire, move to a destination or otherwise interact with a particular container designated by the MCS command. The transport controller selects the CLCs based on the transport system topology, the content of the MCS command and knowledge of which regions of the transport system are controlled by respective CLCs. Each CLC implements the sub-commands by issuing to the intelligent drivers low level control commands to accelerate, elevate, rotate, load or unload the container.

Abstract: An inner rigid pulley core is formed from a plurality of plate members extending radially from a centrally disposed shaft; or a predetermined axis of rotation at which the plate members meet and are connected together in the absence of a shaft. A cylindrical pulley shell is secured to the free ends of the plate members to form with the rigid pulley core a pulley with a face which in total acts as a beam (composite type). In one of the embodiments, where the radial plates are secured to each other, about the predetermined axis of rotation, the axial ends of the plates are extended near the axis of rotation on each end of the pulley to form ears about which an annular ring is secured to form shaft ends to facilitate mounting of the pulley. In another embodiment (where the plates are secured together about the axis of rotation) a cast end bell with stub shaft ends is secured to the pulley core and shell to facilitate mounting of the pulley.
