Abstract: The device 1 for positioning the measuring element of a measuring apparatus comprises a traverse 14 on which the measuring element is arranged. The device further comprises a track 11 on which bearings 12, 13 run, and on which the traverse 14 is held by means of bearings 124, 125. The measuring element of the measuring apparatus can be positioned radially in relation to the track 11 and along the track 11. The traverse 14 comprises multiple components, wherein the components 141, 142 of the traverse 14 are interconnected with one or several bearings 143, or the components 141, 142 of the traverse 14 are held inside each other so as to be telescopically slidable. Radial positioning takes place in that the angle ?14 between the components 141, 142 of the traverse 14 is changed or in that in the case of a telescopic traverse 14, which constitutes a chord in the track 11, the length is altered.

Abstract: The apparatus for the positioning of a measuring device has an annular or arcuate track to which a measuring device is attached. To position the sensing head of the measuring unit radially with respect to the material under test, a crossbeam is provided which supports the measuring device. Bearings are arranged between the track and the crossbeam. In the apparatus for positioning, the position of the crossbeam with the measuring device can be changed in a radial direction to the track with respect to the track.

Abstract: An apparatus for applying a coating of solid particulate powder to the interior surface of tubular, cylindrical articles includes a conveyor for transporting the articles to and from a powder spray station whereat powder is sprayed into one open end of the articles. The conveyor includes an endless belt conveyor movable in a direction perpendicular to the spray from the nozzle and the axes of articles supported on the conveyor. The articles are supported on the conveyor by lugs in the form of rollers which support the articles in grooves defined between adjacent pairs of lugs.
