Abstract: In the case of a horizontally and vertically acting viscous vibration damper for damping vibrations of large masses exhibiting large amplitudes, at least one tube is disposed within the damper casing filled with viscous damping medium. Although this tube is able to move freely in the horizontal direction, i.e. parallel to the damper casing base, it is prevented from moving in the axial direction. The damping characteristics are thereby maintained, even in the event of vertical vibration movements.

Abstract: An elastic support unit has a supporting element including an elastic part and a sliding part arranged so that under the action of load, first the elastic part is elastically deformed and the supporting element acts within a first elastic region, then the sliding part allows the supporting element to slide over a slide path and the supporting element acts within a second sliding region, and thereafter upon passing the sliding region the supporting element uses its stress reserves and after exceeding the stress reserves uses plastic deformation of the elastic part, so as to form thereafter an elastic stop and thereby act in a third additional region.

Abstract: A vibration damping adjustable support for machines. A base plate supports elastically a machine. A bearing element is disposed below the base plate for supporting the base plate and an adjustment device is provided for changing the supporting condition of the bearing element. A regulating provision is furnished for effecting a change in the support conditions for a shafting arrangement of an elastically supported machine by way of changing the supporting forces. Depending on the deviations from a set point value found with a surveying measurement device the supporting force of spring bodies disposed below the base plate are changed until the set point is reached again. In this manner relatively small deformations of foundations of the base plate can be achieved by way of relatively large adjustment distances at the elastic supporting element for aligning and realigning of shafting arrangements.
