  • Sprocketed film transport
    Patent number: 4029405
    Abstract: A motion picture film and sound editing-projecting system which utilizes a single sprocket wheel to advance the film and which includes record and reproduce heads within the sprocket wheel. The sprocket wheel is directly connected to the armature shaft of a stepping motor, and a flywheel is frictionally coupled to the armature shaft to eliminate the cogging effect without preventing rapid acceleration.
