An x-ray technique-based nonintrusive inspection apparatus is provided which is capable of inspecting 600 containers an hour which is small, and which is easily maintainable. Features of the apparatus include 'radiation locking' with 'active curtains', &#x201c;continuous scanning&#x201d; utilizing an x-ray line scanner subsystem and a CT scanner subsystem, good structural integrity, radiation containment in a self-shielding manner, an easily maintainable driving arrangement, shielding curtains that can be raised and lowered quickly, a container jam release mechanism, and efficient air conditioning.

Machines having torques variable as a function of the angle of rotation such as piston driving mechanisms like compressors, cam driving mechanisms, printing machines and looms, are driven by an electric motor in such a way that a trend in angular velocity which is dependent upon the angle of rotation, in particular also a constant angular velocity of the main driving shaft (2) of the driven machine, may be predetermined. To do this the angle of rotation (3) as well as the torque (4) are picked up off the main shaft (2) and fed to an adaptive control system (S) which, starting from the desired values (s0) of the angular velocity as a function of the angle of rotation, applies a corresponding correcting variable (Y) to the electric motor (1) and iteratively adapts it periodically in order to bring the trend in angular velocity of the main shaft (2) into agreement with the desired value (s0).
