Abstract : The work includes the preliminary design of the overall system operation shown by block diagrams of the subsystem functions and operations and timing diagrams for the three modes of ultrasonic inspection: reflection, transmission, and Delta-Scan. Progress to date includes the completion of the design of the X-Y scanner, the purchase of a 4 x 6 x 3-ft tank, and the purchase of the mechanical components, electromechanical controls, and displays necessary for the fabrication of an X-Y scanner capable of operating in the manual or computer controlled mode. The design for the gimbal control is essentially complete with some of the components already in fabrication. A Convair-owned Automation Model UM 771 reflectoscope has been modified to accept programmable gain control from the computer. The electronic circuitries for the gating and computer interfacing have been designed and several have been fabricated. (Modified author abstract)
