Abstract: A vibration damper for damping roll vibration of a power unit (2) mounted on a vehicle body (1). The vibration damper (A) is composed of a disc plate (12) fixedly connected to the power unit (2) in a manner that the axis of the disc plate (12) is generally parallel with a roll axis of the power unit (2). The disc plate (12) is sealingly disposed in a chamber (11a) formed in a generally circular casing (11) which is coaxial with the disc plate (12). A viscous fluid is filled in a space defined between the disc plate (12) and inner surface of the casing (11). The casing (11) is formed of a plastic which is higher in linear expansion coefficient than a metal forming the disc plate, thereby allowing the space filled with the viscous fluid to expand along with thermal expansion of the viscous fluid.

Abstract: On the roller shutter shaft (1), via which the roller shutter is guided, two externally located driver wheels (6, 7) are arranged in a fixed manner, while two internally located driver wheels (8, 9) are mounted in a rotationally fixed manner but axially displaceably. Between one externally located and one internally located wheel (6, 8; 7, 9), there is in each case situated a helical spring (10) which surrounds the roller shutter shaft (1), and one end (11) of which is connected in a stationary manner to a wall (4, 5) and the other end (13) of which is connected in a fixed manner to the internally located wheel (8, 9). By axial displacement of one of the internally located wheels (8, 9) into a circular-profile shaped part (16) of the roller shutter shaft (1), twisting of the internally located wheel (8, 9) is made possible. As a result, a torsional force is imposed upon the helical spring (10) which exerts a torsional force on the roller shutter shaft (1). The rotational forces acting on the roller shutter shaft (1) as a result of the weight of the roller shutter can be compensated with this torsional force so that the roller shutter can be stopped and then remains stationary in any position.

Abstract: By determining at least three unbalance measured values which are determined at different measurement speeds of rotation, constraining forces during balancing can be detected with the aid of the evaluation device (7). In this case, at least three unbalance measured values are detected at different measurement speeds of rotation by the evaluation device (7) during one or more unbalance measurement passes. The evaluation device (7) forms at least two differential values of the unbalance measured values, which are adjacent to one another in terms of speed of rotation, per correction plane from these unbalance measured values. If this results in differential values which are smaller at higher speeds of rotation than at lower speeds of rotation and in which case the reduction follows a quadratic characteristic, a constraining force is detected and signalled. <IMAGE>

Abstract: In a potato harvester having a screening and conveying chain (2) ascending rearwards after the swath pick-up device (8), and furthermore having a leaf chain (9) which follows the screening and conveying chain and which rotates round a separating band extending transversely, the separating band consists of two separating-band portions (1a; 1b) conveying in opposite directions from the middle to the sides. These separating-band portions (1a; 1b) are designed for throwing off the undesirable constituents on different sides of the machine and for transferring the potatoes onto respective following conveying and sorting bands (4a; 4b) extending forwards from the rear. The split design of the separating band results in an especially clean separation between leaves, undesirable constituents and potatoes, even on four-row versions of the potato harvester with double the crop quantity in comparison with a two-row version. <IMAGE>

Abstract: A seat belt retractor (10) includes a mechanism for reducing the tension in the seat belt webbing (16). The retractor also includes a rewind spring (40) which biases a retractor spool to wind the webbing onto the spool (16). The tension reducing mechanism comprises a comfort spring (104) which is selectively engaged to counteract the biasing force of the rewind spring. The counteracting force of the comfort spring is applied throughout any range of movement of the vehicle occupant with the webbing fastened around the occupant. The amount of the counteracting force may be varied by the occupant. The comfort spring is engaged to oppose the rewind spring throughout winding up and unwinding of any length of webbing which is wound onto the retractor spool after the webbing is fastened around the occupant. The counteracting force of the comfort spring is proportional to the length of webbing wound onto the retractor spool while the webbing is fastened around the occupant.
