摘要： A winder for continuous winding of a material web, like a paper or board web, on a winding spool to form a wound reel. A contact pressure drum is rotatably supported on a displaceable transport device and the drum itself is displaceable with respect to the transport device to form a widening nip with the wound reel. The transport device also supports a primary bearing for holding an empty spool during the start of the winding process. The bearing for the empty spool is between the contact pressure drum and a secondary bearing for supporting the wound reel in the final winding position. The primary bearing for the initially empty spool is fixed in location on a transport device. The transport device is in turn transportable toward and away from the secondary bearing for the wound reel. The contact pressure drum is supported to move along with the transport device as well as also being displaceable with respect to the transport device to maintain the line pressure during increase in the wound spool diameter.

摘要： Method for the conversion of the enantiomers of .alpha.-lipoic acid into the corresponding racemic mixture by racemizing the .alpha.-lipoic acid (pure optical isomers of .alpha.-lipoic acid or mixtures of optical isomers of .alpha.-lipoic acid wherein one of the optical isomers is present in excess) at temperatures of between 110.degree. C. and 200.degree. C. at pressures of from normal pressure up to 50 bar for a reaction time of 10 to 48 hours.
