Abstract: A vibration damping method on a vehicle wheel suspension is provided in which, in a hydraulic vibration damper, the damping force increases highly progressively as a function of the piston speed, especially in the range of a piston speed of essentially 0 to 2 m/s, increasing at first slowly and essentially linearly and then especially beyond a piston speed of essentially 2 m/s increasing highly progressively.

Abstract: A calender for a sheet material, e.g., paper, having at least two treatment stations through which the sheet material passes in succession. To regulate a desired parameter of the sheet material, each treatment station may include a plurality of adjacently arranged adjustment zones positioned in a row extending across a width of the sheet material. The adjustment zones of one of the treatment stations are positioned to be offset relative to the adjustment zones of the other treatment station by a fraction of a width of the adjustment zones, e.g., one-half the width. The particular arrangement enabling improved correction potential without increasing structural expenditure.

Abstract: A calender includes at least one roller stack. The upper roller and lower roller of the roller stacks are deflection compensation rollers. The upper roller and/or the lower roller have an outer covering made of a flexible plastic and is designed to bend easily. The roller adjacent to the upper and lower roller is a hard roller.

Abstract: A bearing for a heated calendar roll comprises a bearing ring having a first surface. The bearing is rotatable about an axis. A first radially fixed hydrostatic bearing arcuate segment has a first surface which mates with the first surface of the bearing ring. The hydrostatic bearing has at least one bearing pocket. The bearing pocket has a device for permitting hydraulic fluid to flow into the at least one bearing pocket. The hydrostatic bearing is disposed substantially at a circumferential position with respect to the bearing which corresponds to a bearing load from the calendar roll. A second hydrostatic bearing arcuate segment has a first surface which mates with the first surface of the bearing ring. The second hydrostatic bearing has a first radially adjustable bearing pocket. The radially adjustable bearing pocket has a device for permitting hydraulic fluid to flow into the radially adjustable bearing pocket.

Abstract: A method and apparatus is provided to convey materials in strip form by air pressure floatation. Plenums are provided along the path of floatation to alternately create positive and negative air pressure support areas which induce a wave-like conveying motion to the strip.
