The invention relates to a drive unit for rotationally and linearly moving a working element (3) with respect to a first housing element (1), wherein the drive unit comprises a first and a second motor (7, 8). In order to permit a simple design and a simple mounting and to reduce the required axial installation space and the costs, the drive unit has bearing means which, in the case of a linear movement of the working element (3) with respect to the first housing element (1), permit a primary part (7a) and a secondary part (7b) of the first motor (7) and/or of the second motor (8) to be arranged in an axially non-displaceable fashion.

The invention relates to a material measure for a position measuring device, comprising at least one measuring track with incremental markings and at least one measuring track with absolute markings. The invention also relates to a position measuring device comprising a material measure according to the invention and a scanning unit that can be moved in relation to said measure for scanning the incremental markings and the absolute markings. The aim of the invention is to provide a material measure for a measuring system that is simple and cost-effective to produce, permits the determination of an absolute position and overcomes the disadvantages of prior art. To achieve this, the material measure according to the invention is characterised in that the incremental markings are formed by magnetically active elements and the absolute markings by magnetically passive elements.

The invention relates to a device for receiving a workpiece for a workpiece carrier circulation system of a production machine, comprising a workpiece carrier with a workpiece receiver and a holder arranged on the machine for receiving the workpiece carrier in a detachable, temporary manner. According to the invention, the workpiece carrier (1), which can be received in the holder (18) and rotated around an axis (D), has a rotor section (5), which interacts with a stator (20) provided on the holder (18) when the workpiece is received in the holder (18) by forming a torque motor.

The invention relates to a rotary-table bearing assembly, comprising: a rotary-table bearing, which has an inner ring, an outer ring, and rolling elements arranged in one or more rows, which roll on the inner ring and on the outer ring; and in each case an assembly component having a clamping segment, to which assembly components the outer ring and the inner ring are connected. According to the invention, the clamping segment (16, 28) of at least one assembly component (3, 4) is designed radially elastic on the assembly component (3, 4), and/or the outer ring (11) and/or the inner ring (12) has a radially elastic connecting segment (25), by means of which the particular ring (11, 12) is connected to the assembly component (3, 4).

A drive device (10) for a valve (1), to a valve (1) for controlling a gas and/or liquid flow (40), and a system (60) for controlling a medium (40). The drive device (10) has a housing (11) for accommodating a coil (17d), which is fixed with respect to the housing (11), and a drive rod (14), on which a pole shoe (15d) and a permanently-magnetic element (16c) that is magnetized, or a soft-magnetic element (16c) that can be magnetized, in the axial direction of the drive rod (14) are attached such that the drive rod (14) can be moved with a translational motion relative to the coil (17d) by magnetic force. The drive rod (14) can be coupled to a shut-off body (33) of the valve (1) that can be moved with a translational motion such that a translational motion of the drive rod (14) affects a translational motion of the shut-off body (33) for opening and closing the valve (1).
