PCT No. PCT/SU88/00048 Sec. 371 Date Jun. 19, 1989 Sec. 102(e) Date Jun. 19, 1989 PCT Filed Feb. 29, 1988 PCT Pub. No. WO89/05451 PCT Pub. Date Jun. 15, 1989.The scanning device for ultrasonic control of articles comprises a suspension assembly (7) for mounting ultrasonic transducers on a motion mechanism (6) of the scanning device. The assembly (7), in its turn, includes flexible members (8) positioned above a surface (4) of an article (2) under inspection, having ultrasonic transducers (1) fixedly mounted thereon and contained within a housing (3), a beam (9) extending above the flexible members (8) and mechanically connected therewith, two self-aligning supports (10), each including two parts, that is, an arcuate member (16) and rollers (17) so arranged with respect to each other that their relative displacement takes place about a rolling axis (15) common to both supports (10), extending along the surface (4) of the article (2), and two rockers (11) operatively connected to the beam (9) and to the motion mechanism (6).
