An apparatus is provided for releasably coupling a drawer to a rail, which can be pulled out in a longitudinal direction, of a drawer pull-out guide. The apparatus has a holding part which interacts with a mating holding part in the coupled state in order to establish the releasable connection. At least that region of the holding part which comes into contact with the mating holding part is made flexible, preferably by attaching a flexible piece of material, so that any longitudinal play of the drawer which may occur in relation to the rail can be compensated.

A rotor for an electric motor having a short-circuit element that has lamination packets in which the laminations of the short-circuit element are embodied with spring elements which press from two sides against permanent magnets of the rotor and as a result center the permanent magnets in the lateral direction independently of production tolerances. After the insertion of the permanent magnets between the spring elements, the short-circuit element with the permanent magnets is potted, for instance with synthetic resin, or spray-coated with plastic. The rotor has the advantage that it compensates for production tolerances of the permanent magnets.

The present invention discloses a sled mechanism for the optical pick-up head, which utilized a drive motor to drive a worm to make a worm wheel rotate. After driven by the worm, the worm wheel will drive a spur gear, which is engaged with a rack and drive the rack forward and backward, and then move the optical pickup head attached to the rack to the right position. In the meanwhile, a set of spring unit is utilized to compensate the tolerance of the components of the gear set.

The invention relates to a combing device for combing a fibrous material (F) which is supplied to a clamping assembly (1) that is supported in a machine frame (MS) and has a lower and upper clamping plate (2, 3), wherein the upper clamping plate (3) is movably supported with respect to the lower clamping plate (2) so as to form a clamping point (KS) and is pressurized by a loading unit (B1, B2) so as to produce a clamping force, and furthermore is provided with a feeding means (5) for intermittently supplying the fibrous material (F) to the clamping point (KS) of the clamping assembly, with which beneath thereof a combing cylinder (16) is associated that is rotatably supported in the machine frame (MS) and provided with at least one combing segment (19) on the periphery thereof, and wherein said plate is also provided with a tear-off means (8) associated with the clamping assembly. In order to obtain an improved loading device for the upper clamping plate which compared to the known solution exhibits good damping properties and has a low noise level, according to the invention the loading device is composed of bellows cylinders (B1, B2) which are pressurized with compressed air by way of a compressed air source (26) and which, with one end (35) thereof, are directly or indirectly supported on the machine frame (MS) and which, with the other end (30) thereof, are supported by elements (4a, 4b, 28) connected to the upper clamping plate (3).
