Abstract: An opto-electronic, threaded parts inspection device. The device includes a source for generating a thin, planar beam of collimated light which is disposed on one side of a parts carrier. The laser light beam is rotatable about two axes, normal to one another and both normal to the longitudinal axis of parts passing through the beam. A sensor unit is disposed on the other side of the parts carrier so that the light beam falls thereupon. The threaded parts inspection device can be adjusted to pass light over different features of the threaded parts as they are moved past the inspection device by the parts carrier. By measuring how much of the light is interrupted by the profile of the passing threaded parts, it is possible to detect deviations in the pitch angle and major and minor diameters of the threaded workpieces.

Abstract: A diverter for redirecting a single member or portion of a generalized set of material passing thereby. The device includes an electromechanical actuator which moves from an extended to a retracted position. A flexible strip has a first end attached to actuator and a second end fixed with respect to the actuator. The device is positioned proximate a gravity slide down which a stream of material moves in a first direction. When the actuator moves from its extended to its retracted position, the resilient strip flexes out into the path of the moving material. Any of the material striking the flexible strip will be deflected into a second direction which diverges from the first direction.
