COMPUTER DEVICE FOR ULTRASONIC INSPECTION Russian patent published in 1994 - IPC

FIELD: analogue-graphic computer engineering. SUBSTANCE: device has a housing with an orthogonal scale grid applied onto it, central and auxiliary slots formed in the housing and receiving central and auxiliary slides, a runner moving along the perimeter of the housing cross-section, flexible tape driving unit. The central slide has trajectories of forward and reflected ultrasonic beams applied onto it. The auxiliary slide has a distance scale applied onto it. The runner has a rectangular transparent window with scales applied onto its orthogonal frames. The closed transparent flexible tape with images of a hair-line and standard types of preparation of edges of articles to be welded is wound around the driving unit, the flexible tape being movable around the housing. EFFECT: widened range of problems to be solved and enhanced speed. 1 dwg
