    • Fault tolerant operation is disclosed for a primary instance, such as a process, thread, application, processor, etc., using an active copy-cat instance, a.k.a. backup instance, that mirrors operations in the primary instance, but only after those operations have successfully completed in the primary instance. Fault tolerant logic monitors inputs and outputs of the primary instance and gates those inputs to the backup instance once a given input has been processed. The outputs of the backup instance are then compared with the outputs of the primary instance to ensure correct operation. The disclosed embodiments further relate to fault tolerant failover mechanism allowing the backup instance to take over for the primary instance in a fault situation wherein the primary and backup instances are loosely coupled, i.e. they need not be aware that they are operating in a fault tolerant environment. As such, the primary instance need not be specifically designed or programmed to interact with the fault tolerant mechanisms. Instead, the primary instance need only be designed to adhere to specific basic operating guidelines and shut itself down when it cannot do so. By externally controlling the ability of the primary instance to successfully adhere to its operating guidelines, the fault tolerant mechanisms of the disclosed embodiments can recognize error conditions and easily failover from the primary instance to the backup instance.

    • An improved conveying system in a parallel processing production line for dynamo-electric machine components having a magnetic core, the conveying system having a main conveyor extending along all of the processing machines of the production line and a load/unload device for transferring components between the main conveyor and a selected processing machine. Components to be processed are loaded directly from the main conveyor onto the load/unload device without the use of an intermediate conveyor. The load/unload device has a base platform with an alignment area at which transfer between the load/unload device and either the main conveyor or a selected processing machine occurs. Two component holders (e.g., collets) are movably mounted on the base platform for alternate positioning at the alignment area. The load/unload device alternately positions the gripping ends of the component holders adjacent the main conveyor and a selected processing machine. The central axis of the load/unload device remains fixed during movement of the load/unload device.
