Abstract: A system and method for non-destructive examination of parts using three-dimensional CT imagery. The system comprises a computer controlled x-ray source, a scintillator screen, and an amorphous silicon sensor array, which electronically records and transmits a series of images taken from different angles back to the computer system having a CAD/CAM software program. The part being examined is stored as a CAD/CAM record. The various images from the silicon sensor array are stored in the computer system and reconstructed as a three-dimensional CT image. That CT image is converted to the CAD/CAM coordinate space so a comparison between the CT image and the stored drawing of the part being examined may be made to detect any defects in the part. The overlaid or superimposed images are displayed for an analyst so that determination of a defect and a location can be made.

Abstract: A portable chain lock for a chain binder used to tighten a chain holding a load on a truck flat bed. The portable chain lock has an open body with a pin fixed to a bottom wall and extending outwardly between a pair of sidewalls. One of the sidewalls has the first end of a locking chain fixed thereto while the other sidewall has a holding arm having an opening fixed thereto. The pin is passed through a chain link or other opening in one half of the chain binder when the chain binder is in the tightened position. The locking chain is wrapped around the other half of the chain binder with its second or free end looped over the holding arm and secured to the holding arm by a padlock passed through the opening in the holding arm, to thereby lock the chain binder in the chain tightened position.
