Abstract: The invention relates to a crepe facilitating aqueous composition comprising at least one water-insoluble, non-surface active thermoplastic material having a softening or melting point within the range of from 40° C. to 100° C., and at least one water-soluble polymer, preferably a cationic water-soluble polymer. As the composition is comprised in a wet fibre web during creping thereof, a more uniform creping is obtained while the integrity of the web is preserved and dust formation is reduced, and a tissue product having improved properties is provided.

Abstract: Elastic bearing comprising an inner bushing and an outer bushing located at some distance from it, and an elastic part inserted between them, whereby between the elastic part and at least one surface of one of the bushings, there is lubricant in a cavity, the bushings and elastic part being rotatable relative to one another. To increase the useful life and to guarantee correct lubrication, in the cavity the elastic part has elevations on its surface, which are arranged to guarantee a proper distribution of the lubricant.

Abstract: A hydraulically damping elastic bearing comprises an outer tubular member and an inner tubular member disposed radially inwardly of the outer tubular member to be separated therefrom. An elastic member is disposed between the inner and outer tubular members and has at least one chamber filled with a damping medium. At least one elastic radial stop is mounted to extend at least partially from the outer tubular member toward the inner tubular member. The elastic radial stop is disposed outside of and displaced from the chamber of the elastic member. Such an elastic radial stop may be resiliently deformed to produce a radial force on the inner tubular member and the outer tubular member by a wedge which is disposed between an extended end of the elastic radial stop and the inner tubular member. Alternatively, the extended end may be radially spaced from the inner tubular member by a predetermined radial distance and a different wedge may be disposed between the extended end and the inner tubular member.

Abstract: Bearing for the elastic mounting of machines, machine parts and/or vehicle parts in which the rubber body located between the fasteners is designed so that the oxygen in the atmospheric air cannot come in contact with the rubber body. For this purpose the surface of the rubber body facing the atmosphere is covered by a liquid-tight membrane which is impermeable to gas and/or oxygen, and the cavity betwween the rubber body and the membrane is filled with an inert gas and/or an inert liquid. Alternatively, the surface of the rubber body facing the atmosphere can be coateed with a gas-tight, elastic material.

Abstract: Hydraulically damping elastic bearing with two rigid end walls opposite one another in the axial direction, and at least two chambers located one behind the other and containing damping fluid, at least one of which has a circumferential wall designed as an elastic spring element, whereby the chambers are separated from one another by a partition which is at least partly elastic exhibiting slits for an exchange of fluids. The elastic partition should thereby be designed so that when there is flow against the membrane from different chambers at the same pressure, a different pressure reduction is possible. For this purpose, the elastic partition is asymmetrical in cross section in relation to its center line, at least in the area of the slits, so that the opposite surfaces of the elastic partition are at different distances from the center plane in the area of a slit.

Abstract: Hydraulic damping single-chamber mounting for motor vehicles with two rigid end walls axially disposed opposite one another, and at least two chambers containing damping fluid disposed axially behind one another. In a first of the two chambers, the damping fluid can be both compressed and decompressed. A rigid partition separates the two chambers. The partition is fixed and rigidly clamped on its outside circumference. The chambers are in communication with one another by means of a circular channel running around a central axis of the rigid partition. The rigid partition is located radially inside an elastic, axially-movable membrane. The membrane is fixed and rigidly clamped on its outside circumference. The rigid partition has at least one overpressure valve which operates for each direction of positive pressure between the chambers to prevent noises during cavitation in the decompression phase and pressure peaks in the compression phase within the first chamber.

Abstract: A hydraulic-damping rubber mounting for motor vehicles, particularly for engines of such vehicles, has two rigid end walls which are disposed opposite to each other in the axial direction, and at least two fluid chambers which are disposed axially one behind the other, for containing damping fluid. The chambers communicate with each other through a throttle means. A partitioning wall which delimits and separates the two chambers is axially movable, and is pressed against a sealing surface by way of a prestressed rubber spring so that, at large amplitudes, the reduced pressure which normally might cause cavitation in a chamber is eliminated by way of a bypass opened by stressing the rubber spring so as to open communication at the sealing surface, such that no interfering noise effects occur.
