    Abstract: A capacitive measuring device has a scale and a transducer, both provided with an array of electrodes. The position of the transducer with respect to the scale is determined in a processing circuit by evaluating the capacitances formed between the two arrays. These capacitances vary periodically as a function of the relative position of the transducer. The scale electrodes are spaced by a pitch (.lambda.). In order to increase the resolution, the transducer electrodes occupy possible initial positions spaced by an elementary interval (P) which is a submultiple of the pitch (.lambda.). The transducer electrodes are thus divided into N groups according to the initial position which they occupy. In order to compensate for manufacturing imprecisions of periodic type, the succession of transducer electrodes is highly non-periodic. To this end, the set intervals (I.sub.j) occupied by the sets of successive electrodes interpenetrate, and the number of unoccupied possible initial position between the bundles of electrodes is variable. A set of electrodes is a set composed of one electrode of each group.

    Abstract: Motorized indexed measuring head for a machine for measuring three-dimensional coordinates. Comprises one, two or more re-orientable elements to orient a probe feeler according to a plurality of indexed orientations. The orientable elements are guided in their rotation and sliding movements by undercut bushings and undercut shafts. The arrangement of the undercuts allows an accurate guiding in the rotation movement without impairing the indexing accuracy.

    Abstract: Method enabling a command to switch the measure mode to be entered in a single vertical axis dimension-measuring column. The mode witch command is entered by pressing the probe tip against the piece to be measured during a time interval greater than a predetermined value. The measuring and displaying system then engages in a search mode of the turn-back point of said piece to be measured.Application: measurement of inner or outer diameters by means of a single-axis measuring column. The method allows the hole's minimal and maximal points to be determined with a minimum of handling operations.

    Abstract: Tool rack for tools of a coordinate measuring machine, wherein the guiding and retaining surfaces of the tool rack are arranged on two planes offset vertically so as to cause the tool to tilt when it is unhooked. The inventive arrangement allows the mechanical efforts during uncoupling to be reduced appreciably. This reduction is due to the tool tilting and to the residual magnetic force being divided between three retaining point, with a positive effect on the coupling precision and on the tool positioning in the tool rack.
