Abstract: A work chamber is filled with a hydraulic liquid and is disposed between the legs of the spring body of a hydraulic radial bearing. The work chamber is connected to a compensating chamber via a transfer channel. The desired absorption of disturbing noises in the region of 130 Hz is obtained with a special dimensioning of the cross-sectional area of the work chamber, the dynamic swell stiffness of the spring body and the length (L) and the total cross-sectional area (A2) of the transfer channel. The ratio of the effective cross-sectional area (A1) of the work chamber to the cross-sectional area (A2) of the channel lies preferably between 0.1 and 10 while the ratio of the length (L) of the transfer channel to the total cross-sectional area (A2) of the transfer channel is in the range of 0.1 to 4.0.

Abstract: A volume-changeable work chamber (10) is filled with a hydraulic liquid and is disposed between the legs (8a, 8b) of the spring body (8) of a hydraulic radial bearing (2). The work chamber (10) is connected to at least one compensating chamber (20a and/or 20b) via at least one transfer channel (14a and/or 14b). the desired absorption of disturbing noises especially in the region of 130 Hz is obtained with a special dimensioning of the cross-sectional area (piston surface, A) of the work chamber (10), the dynamic swell stiffness of the spring body (8) and the length (L) and the total cross-sectional area (A2) of the at least one transfer channel (14a and/or 14b). The ratio of the effective cross-sectional area (A1) of the work chamber (piston, 10) to the cross-sectional area (A2) of the at least one channel (14a and/or 14b) lies preferably between 0.

Abstract: The invention relates to a process for the stereoselective preparation of cyclohexylcyanohydrins by reaction of 4-substituted cyclohexanones with a cyanide source in the presence of an oxynitrilase.

Abstract: A method for producing (S)-cyanohydrins of general formula ##STR1## in which R and R' independently represent (1) hydrogen; (2) a substituted or unsubstituted saturated alkyl group which may include amine, imine, hydroxy, C.sub.1 -C.sub.8 -alkoxy, halogen, carboxyl, C.sub.3 -C.sub.20 -cycloalkyl groups and/or a N,O,S-heteroatom-substituted aromatic ring as substituent; (3) a substituted or unsubstituted, singly or multiply unsaturated alkenyl- or alkinyl group which may include one or several amine, imine, hydroxy, C.sub.1 -C.sub.8 -alkoxy, halogen, carboxyl, C.sub.3 -C.sub.20 -cycloalkyl groups and/or one optionally N,O,S-heteroatom-substituted aromatic ring as substituents; (4) a substituted or unsubstituted aromatic or heteroaromatic group.

Abstract: A mount is formed from a rubber-metal mount and a damping device inserted therein. The rubber-metal mount is comprised of two support members interconnected by an elastomer member. The damping device has an inner hydraulic chamber and an outer hydraulic chamber which are interconnected through throttle passages and an annular passage. When the mount is to be used for operation without the damping device, the damping device is simply omitted.

Abstract: An engine mount has two support members which are interconnected by an elastomer element. The elastomer element is surrounded on its outer side by an annular chamber that forms a first hydraulic chamber to effect hydraulic damping of the engine mount. A second hydraulic chamber is provided inside the elastomer element. And the hydraulic chambers are in fluid communication with one another via throttle passages and an annular passage.

Abstract: A hydraulic mounting has a nozzle plate with a membrane separating a working chamber from an equalizing chamber and a ring channel connecting these chambers. A filler channel leads radially from the outside into this ring channel and makes it possible to fill the hydraulic mounting, without air bubbles, with hydraulic fluid. A closure member closes off the filler channel on the outside.
