Abstract: The invention relates to a device for processing objects, said device being provided with a number of stations comprising supporting means for supporting objects in said stations, and with conveying means, by which the objects can be moved from one station to another station. A transport means, which is capable of rotating movement about a vertical axis of rotation and translating movement parallel to said axis of rotation, is fitted with gripping means for gripping and moving the objects between the various stations. The transport means is supported by at least three spaced-apart carriers, which are in turn supported by sliding pieces, which are journalled in such manner as to be capable of sliding movement in vertical direction. Two hinged-together links are provided between a sliding piece and the frame, one being hinged to the sliding piece, the other being hinged to the frame and both being hinged to a connecting rod which is movable in a plane extending transversely to the axis of rotation.

Abstract: A method and apparatus for scanning a rotating optical disc record carrier with a radiation beam which forms a scanning spot on the carrier and which is moved radially relative thereto. Pulses are generated at a frequency proportional to the angular velocity of the carrier, and clock pulses are generated at a constant frequency differing from and preferably higher than that of the velocity pulses. In response to each velocity pulse an accumulator is incremented by a first correction value (INC) and in response to each clock pulse the accumulator is decremented by a second correction value (DEC). The angular velocity of the record carrier is controlled to maintain a constant value of the average of the sum output of the accumulator over the intervals between successive velocity pulses, and the correction values are adjusted so that the ratio thereof is maintained proportional to the radial distance between the scanning spot and the axis of rotation of the carrier.
