Abstract: A process for chiral separation of ethyl 3-amino-1-[(3R,4S)-4-cyanotetrahydropyran-3-yl]pyrazole-4-carboxylate (VI) from the racemic mixture of ethyl 3-amino-1-[(3R,4S)-4-cyanotetrahydropyran-3-yl]pyrazole-4-carboxylate and ethyl 3-amino-1-[(3S,4R)-4-cyanotetrahydropyran-3-yl]pyrazole-4-carboxylate (V).

Abstract: A chassis of modular construction for commercial vehicles has a front vehicle subframe and a rear vehicle subframe connected thereto, an individual wheel suspension having a spring and/or shock-absorber strut and also an upper transverse link and a lower transverse link formed on the front vehicle subframe on each side of the vehicle. The front vehicle subframe is composed of two side consoles assigned in each case to one side of the vehicle, an upper crossmember connecting the two side consoles to each other at the top and a lower crossmember connecting the two side consoles to each other at the bottom. Each side console is connected to the rear vehicle subframe. One of the upper transverse links is mounted on each side console and one of the spring and/or shock-absorber struts is supported thereon. The two lower transverse links are mounted on the lower crossmember.

Abstract: A supporting structure of a commercial vehicle, e.g., a lorry, includes an axle support element, a front element and a longitudinal member element. The axle support element has, on each side of the vehicle, an axle-support side part which has a front attachment end, for the fastening of a longitudinal member of the front element, and a rear attachment end, for the fastening of a longitudinal member of the longitudinal member element. The attachment ends of the axle-support side part are configured in such a manner that the longitudinal members may be fixed on along the respective attachment end at a plurality of points which differ from one another with regard to the vertical level, based on an underlying surface on which the vehicle is standing.

Abstract: A headlight device for motor vehicles has a light source for emitting light beams, a reflector for reflecting at least a part of the light beams emitted by the light source in a light outlet direction on a region in front of the vehicle, and a dispersing element which is bringable in beam path of the light beams reflected by the reflector.

Abstract: A motor vehicle headlight assembly switchable between low-beam and high-beam modes of operation includes a housing, a reflector component mounted in the housing for displacement relative thereto between a plurality of beam aiming positions, and a light source component mounted in the housing for movement relative to the reflector component between a low-beam position and a high-beam position. A motor is provided for displacing the reflector component between the plurality of beam aiming positions relative to the housing. To selectively move the light source component between, and for holding the light source component in at least one of, its low-beam and high-beam positions relative to the reflector component, use is being made of the motor and of an electromagnet operated in sequential cooperation with the motor.

Abstract: A headlight for a low beam and a high beam in a vehicle has a reflector, a light source, an adjusting device operative for displacing the light source relative to the reflector between a position for a low beam and a position for a high beam, the adjusting device including holding means which produce a holding force for fixing the light source in one of the two positions.

Abstract: In an arrangement for mounting a fuel tank to the undercarriage of a motor vehicle by way of a support bracket and a tension strap extending around the fuel tank, the support bracket includes means engaging one end of the tension strap while the other end of the tension strap forms a loop portion with a bore and a connecting member having one end with a threaded shaft extends through the bore and through a transverse connecting member for engagement with the loop and the other end of the shaft has a hook-like head hooked into an eyelet in the bracket. A nut is threaded onto the threaded end of the shaft for tightening the tension strap and holding the fuel tank in firm engagement with the bracket.

Abstract: The headlight has a light source (10) in the form of a gas discharge lamp and a reflector (12) which has a first reflector part (16) and a second reflector part (18). A converging light beam is reflected from the first reflector part (16) and a lens (26) and a stop (22) with an edge (24) for producing a light-dark boundary are arranged in the path of that beam. The second reflector part (18) is arranged above and/or beside the first reflector part (16) and is moveable between a position for low beam light, in which a light beam directed downward is reflected from it, and a position for high beam light, in which a light beam with a greater range is reflected from it. The light reflected by the second reflector part (18) in the position for low beam light can issue from the headlight and contribute to the formation of the low beam or be absorbed inside the headlight.

Abstract: Steam generator for nuclear power plants including a cylindrical housing, a tube bundle for conducting primary medium enclosed by the housing, at least one tube support plate holding the tube bundle, the cylindrical housing including a base member secured to the tube support plate and defining therewith inlet and outlet chambers for the primary medium, the cylindrical housing having a pair of opposing flanges on portions of the cylindrical housing located on opposite sides of the tube support plate, and flange connection means for tightly connecting the portions of the cylindrical housing on opposite sides of the tube support plate, the flange connection means being releasable for assembling and disassembling the tube bundle and including a stud bolt connection, the flanges having opposing sealing surfaces, a lip seal disposed between the sealing surfaces and having radially outwardly protruding lips tightly welded to one another, the lips having a radially inner region secured by respective circular bead wel
