LINEAERMOTOR-FREMDRIFTSSYSTEM.

摘要

A system for propelling individual carriages along an endless path from a first speed abutted in a stack in a carriage collection section, to a second speed spaced apart in an operational section, and to a third speed in a stack-forming section where the carriages return to the first speed in the stack. Novel carriages are propelled by a linear motor wherein each carriage has attached a synchronous and a hysteresis secondary. A first primary positioned adjacent one part of the path develops electromagnetic waves for engaging the synchronous secondaries to provide controlled spacing of the carriages, and a second primary adjacent another part of the path develops other electromagnetic waves for engaging the hysteresis secondaries to provide controlled abutting of the carriages.
