Abstract
Abstract A transport mechanism having a wheel with uniformly spaced radial peripheral slots adapted to engage the axial leads of diode components transports the diodes, one in each set of peripheral slots from a supply bin past a polarity sensing station which registers the polarity of the diode in the slot and controls a drop gravity gate mechanism subsequent to the polarity sensing station to drop diodes of a given polarity and retain in the slots those diodes of the opposite polarity until the retained diode reaches a subsequent discharge station which includes a physical reversing path between the discharge station and the ultimate delivery point for all diodes whereby diodes delivered from both the drop station and the discharge station are delivered to a common delivery point with uniform polarity orientation.
