Abstract: The invention relates to a method for the production of (R)- or (S)-8-chloro-6-hydroxyoctanoic acid alkyl esters of the general formula (R)-II or (S)-II in which R has the meaning C1-4-alkyl, from 8-chloro-6-oxooctanoic acid alkyl esters of the general formula I in which R has the above meaning, by enzymatic reduction using alcohol dehydrogenases, such as Lactobacillus brevis or Thermoanaerobium brokii, in the presence of cofactor regeneration systems. The resulting (R)- and (S)-8-chloro-6-hydroxyoctanoic acid esters can be converted in a known manner into (R)-?-lipoic acid and (S)-?-lipoic acid, respectively.

C. with a protic acid, and isolating pure tetrahydrofuran and .gamma.-butyrolactone from the resultant reaction mixture by distillation.

Abstract: An elastic engine mount includes upper and lower bearing plates. A hollow-cylindrical spring block has top and bottom ends being clamped between the bearing plates and defining an inner space. A bolt protrudes into the inner space from the upper bearing plate. The spring block is formed of an elastomer and has conduits formed therein with at least one open end and a varying cross section. The conduits are disposed in a plurality of planes and are mutually parallel within each respective plane. A transverse elastic wall for additional damping is centrally fixed to the bolt for dividing the inner space into two liquid-filled chambers. The elastic wall has through openings formed therein and has an outer periphery clamped between the lower bearing plate and the bottom end of the spring block.

Abstract: The substituted 5-(phenoxyalkanoylamino)-uracil compounds have the following formula I: ##STR1## wherein R.sub.1 and R.sub.2 are each independently hydrogen; a branched or linear alkyl group having 1 to 6 carbon atoms; a branched or straight chain alkenyl or alkynyl group having 1 to 6 carbons atoms; a cycloalkyl group having from 3 to 7 carbon atoms or a cycloalkylmethyl group having a cycloalkyl residue of 3 to 7 carbon atoms; or a phenylalkyl group having an alkyl residue having from 1 to 3 carbon atoms and a phenyl residue, the phenyl residue being unsubstituted or having a halogen, methoxy, methyl or trifluoromethyl substituent; R.sub.3 is a hydrogen, methyl or amino groups; R.sub.4 is halogen, methoxy or methyl groups, and n is 1 or 2.

Abstract: The invention is directed to a ventilating apparatus including a ventilating device and a closed breathing circuit wherein fresh gas is metered by means of a controller via a fresh gas line. A reservoir having a changeable volume is connected to the fresh gas line. In this way, at least the quantity of respirating gas which is consumed is again replenished. This arrangement is improved such that a very small quantity of respirating gas can be metered with the compliance of the entire system being low and remaining necessarily constant. With the invention, a system is obtained which is easy to control with the smallest possible configuration and least complex measuring sensors. For this purpose, a reservoir connected downstream of the metering unit is branched off of the fresh gas line and is provided with a level indicator. The signal of the level indicator indicates the level and is supplied as an actual value to the controller and compared to a pregiven desired value.

Abstract: A chassis mount for a vehicle having a chassis and a wheel suspension includes an approximately frustoconical rubber body having a lower surface and being retained in the chassis. A central bushing is disposed inside the rubber body. A bolt has ends and is guided in the central bushing. A fork structure articulatingly connects the ends of the bolt to the wheel suspension. A hydraulically damping mount element has two liquid chambers communicating with one another through an overflow conduit. The chambers include a working chamber with an upper surface. The hydraulically damping mount element is mounted as a modular component onto the lower surface of the rubber body with the lower surface of the rubber body forming the upper end surface of the working chamber.

Abstract: The present invention generally relates to the mounting of panes or windshields in a frame, particularly to the mounting of panes or windshields of a vehicle, e.g. an automobile, in the body frame work. The invention provides a pane or windshield ready to be mounted comprising, along its edges, a first profiled bead of adhesive material, already cured and being elastic but not plastically deformable. The first bead comprises an essentially closed hollow chamber and in its interior a second bead of plastically deformable not yet cured adhesive material consisting of a substance chemically compatible to the material of the first bead. The second bead, serving as the real adhesive material, is protected from environmental influences without the need to remove a cover foil or a packing prior to mounting the window.

C. to 350.degree. C. and pressures of from 50 bar to 350 bar over a catalyst containing cobalt as the active metal and one or both of the elements copper and phosphorus, if necessary in the presence of an aliphatic alcohol.

Abstract: The invention is directed to a pumping arrangement for supplying a ventilating apparatus with breathing gas. The pumping arrangement includes a piston which runs in a cylinder and the piston is connected via a coupling with a drive unit for generating the pumping strokes. The coupling engages a motion transmitter in the form of a piston rod. Gas connecting ports for the breathing gas to be pumped open into the inner chamber of the cylinder. The pumping arrangement permits the piston-cylinder unit to be simply removed and to be reinstalled with reliable guidance. An automatic latching occurs such that a release and removal of the piston-cylinder unit from the ventilating apparatus and its uncoupling from the drive unit is possible only in a rest condition and not during operation.

Abstract: A hydraulic-damping two-chamber engine mount includes a working chamber and a compensating chamber. A conical jacket-like elastomeric wall has an end surface and a bearing plate is disposed on the end surface and borders the working chamber along with the elastomeric wall. The bearing plate has a cylindrical attachment with an end protruding into the working chamber. A rigid intermediate plate has an overflow conduit formed therein providing communication between the chambers. An integrated tension stop in the form of an annular stop plate has an inner edge suspended with play on the end of the cylindrical attachment for damping axial and radial mobility of the stop plate. A substantially conical jacket-like stop ring is provided for engaging the stop plate from above.
