Abstract
Abstract A sorting mechanism for magnetic core handlers utilizing a sort gate or block that is provided with tubular openings, and is directly attached to the output shaft of a conventional stepper motor that has a shaft which can be rotated between a neutral position and at least one position from neutral. The gate is shifted directly by the movement of the motor shaft in response to a test signal for a core being tested, and suitable vacuum means can be supplied to the sorting chambers to exert a vacuum force to pull tested cores through the properly aligned opening in the sort block.
