ABSTRACT:
Ultrasonic leak detection apparatus which includes a cycloidal transfer mechanism for sequentially feeding a plurality of workpieces to a test station. An elevator at the test station alternately lifts workpieces in sequence to an elevated position to a test chamber and lowers workpieces from the test chamber to the transfer mechanism. An enclosure cooperates with the elevator to form the test chamber in which the workpiece is pressurized and microphones detect any leakage of air through cracks or the like. A reject station downstream of the test station includes facility for removing defective workpieces from the transfer line.
