摘要： A manipulator for positioning a part includes a manipulator mandrel, manipulator arms, a pneumatic actuator ball plunger, drive motors, and shaft encoders. The motors drive the manipulator mandrel vertically perpendicular to a plane of directed X-ray beams and one whose rotation axis is vertical and perpendicular to the plane of the directed X-ray beam. The motors include positioning encoders which generate encoding pulses representative of movement of the manipulator mandrel along either axis. The pneumatic ball plunger provides for the acquiring of a gripper which holds a part to be inspected in the X-ray beam. The manipulator mandrel includes two L-shaped arms inwardly extending towards the ball plunger for acquiring a gripper having outwardly extending flanges.

摘要： An X-ray inspection system for manually or automatically performing digital fluoroscopy inspections and/or computed tomography inspections by X-ray examination of manufactured parts incorporates a computer system which automatically analyzes the inspected parts for flaws. The system includes apparatus for automatically positioning the parts in an X-ray machine for obtaining fluoroscopy and tomography views of the part and for acquiring data from the inspections at production rates. The system automatically identifies the location of rejectable flaws in the parts during the fluoroscopy scanning and subsequently identifies those locations for obtaining tomography scans, if the identified flaw location is questionable. The system can automatically reject parts containing flaws identified during the fluoroscopy inspections. This system operates in a real-time environment by providing analysis of one part while a subsequent part is being subjected to X-ray examination. The data obtained during each examination is archived and stored for tracking the part in further manufacturing processes.

摘要： An X-ray inspection system includes an X-ray source for generating a directed X-ray beam and a linear array detector for measuring the intensity of the received radiation and generating electrical signals representative thereof. A method for aligning the detector with the directed X-ray beam includes removing any part between the X-ray source and the detector, opening an X-ray beam limiter, positioning the linear array detector for maximum signal from each detector element, reducing the X-ray beam limiter opening, detecting whether any signal from a detector element is reduced, moving the limiter for producing a maximum signal on each signal, securing the X-ray beam limiter, and positioning the detector array for maximum signal.

摘要： A cable assembly for an electrical signal transmission system comprises a plurality of elongated conductors, a conductive shield surrounding each conductor, and a dielectric layer between each shield and its respective conductor. The shielded conductors are embedded in a dielectric material and the dielectric material is wrapped in a double conductive shield. Adhesive layers are located between the double shield and the dielectric material and between the two shields making up the double shield. This cable assembly results in a signal transmission apparatus which has increased immunity to the effects of external electromagnetic fields, electrostatic charge, and mechanical vibration. It is particularly useful in transmitting low level signals produced by ionization detectors used in x-ray inspection apparatus.

摘要： A gripper for holding a manufactured part in a X-ray inspection system. The gripper includes a stationary jaw, a slidable jaw, a gripper base, a wear plate, a centering bushing an end plate, and a cam actuated spring mechanism for opening and closing the jaws. Both jaws are removable and adjustable in a keyway. Set screws are used to hold the jaws in place for a predetermined separation and allows a part to be positioned off center. The removable aspect allows for various jaw configurations. The centering bushing includes a cam shaped opening for accepting an end of an pneumatic activated ball plunger of a numerically controlled part manipulator. The centering bushing aligns the gripper to the longitudinal axis of the part manipulator.
