摘要： The invention relates to an elastic coupling in disc construction, in particular for damping torsional vibrations of an internal combustion engine, having the following features: a first coupling half, which comprises two side discs, which are connected in a rotationally-fixed manner on the outer circumference; a second coupling half, which is formed by at least one middle disc assigned to a hub, which is arranged between the side discs and enveloped thereby; the two coupling halves are pivotable to a limited extent to one another against the force of at least one elastic coupling element; the side discs delimit a liquid-tight inner space, which receives the middle disc, at least one damping chamber, which is variable in volume during the mutual pivoting of the coupling halves and is filled with a damping medium, is arranged in the radial outer area of the inner space; a floating damping ring, which is pivotable to a limited extent in relation to each of the two coupling halves, is introduced into the inner space, the damping ring forming at least one first partial chamber of the damping chamber with the first coupling half and forming at least one second partial chamber of the damping chamber with the second coupling half; the floating damping ring being divided over the circumference of the coupling into individual ring segments, which are separate from one another, and which are mounted to slide on the radial exterior on the middle disc and/or on the radial interior on an outer edge of at least one side disc. The elastic coupling according to the invention is characterized in the state which is not loaded in the peripheral direction by the damping medium or one of the two coupling halves, the ring segments, at one or both axial ends, have a predefined spacing in the radial direction of the coupling in relation to the middle disc and/or in relation to the outer edge of at least one side disc, and the ring segments are mounted in a bending or tilting manner on the middle disc and/or at least one side disc in such a manner that the predefined spacing at the axial end of the ring segments in relation to the middle disc and/or the outer edge of at least one side disc is bridged by bending or tilting in the state of the ring segments which is loaded in the peripheral direction by the damping medium or one of the two coupling halves.

摘要： The invention relates to a tube for an optical instrument, such as a microscope, having several rotary joints (19, 20, 21) connected serially one behind the other. Each of the rotary joints (19, 20, 21) includes a brake (32, 33, 38) via which the rotary joints are secured against an unintended rotation. The brakes of the rotary joints (19, 20, 21), which are connected serially one behind the other, are simultaneously releasable by actuation of the single operator lever (39). For this purpose, a system of pins (42) and tilt levers (43) is mounted in the tube via which the actuation of the operator element (39) is transmitted to the brakes (32, 33, 38) connected serially one behind the other.
