摘要： A measuring device for hollow cylindrical surfaces, such as bores and the like, comprises a housing to be fixed in the bore by clamps, a measuring arm rotatable by a first step motor, a measuring head axially movable along the measuring arm substantially parallel to the axis of the bore surface by a second step motor and a sensor incorporated in the measuring head and radially movable relative to the measuring head against the force of a leaf spring in contact with the bore surface. The leaf spring supports strain gauges, the output signals of which are representative of the radial or transverse paths of the sensor and thereby for the shape of the bore surface to be measured.

摘要： In a method of opto-electronic inspection of a two-dimensional pattern on an object, especially a printed board, a micro-inspection is carried out by subjecting line-by-line scanned picture elements in pixel-by-pixel fashion to a sequence of picture operations for inspection of dimensions and spacings, and the respective result is compared with the corresponding scanned pixel. At the same time a macro-inspection is carried out by combining the scanned pixels to frames and by respective reduction thereof to a single characteristic picture information, whereupon a comparison is again performed, but this time with the corresponding picture information of a reference picture. In this way it is possible to perform a quick and fully automatic real-time inspection of two-dimensional patterns, for instance printed boards, both for minute and hardly visible defects and for macro-defects.

摘要： A workpiece prepuncturing device for use with a sewing machine having drive means for reciprocating a needle and means for feeding a workpiece into association with the needle to sew a stitch comprises a perforating tool which is located at a spaced location from the needle which is comparable to a multiple of the stitch length. The perforating tool cooperates with a counter tool which is mounted on the opposite side of the workpiece and is movable toward and away from the workpiece in timed relationship to the speed of the feed and the reciprocation of the perforating tool. The counter tool is supported in a base portion of the sewing machine by an elastic suspension, and it is in drive connection with the main shaft of the machine which operates the needle and the feed for the workpiece.

摘要： Method and apparatus for positioning and altitude-stabilizing an inert mass slewable on a movable base in at least one axis are disclosed. Oppositely rotatable driving parts are supported on either the base or the mass, and the driven parts on the other of the base or mass are friction coupled to the driving parts under the control of one or more control devices. The control devices are controllable electromagnetic clutches or brakes, and control of the magnetic field is achieved by the hyperexcitation through feedback and intensification of the measured magnetic field strength and/or the control torque.
