Patent DE-4038674-A1 (DE)
Inventor: TARANTIK KARL DIPL ING
IPC: G01D5/14
Filed: 1990-12-04
Abstract: The device disclosed comprises a coarse-resolution indicator (1) and a fine-resolution indicator (2). Associated with the coarse-resolution indicator (2) is a coarse-resolution magnetic-flux sensor (4). Associated with the fine-resolution indicator (2) are also magnetic-flux sensors (6, 7).

Patent DE-4126580-A1 (DE)
Inventor: BEISSWENGER THOMAS DR
IPC: C07D307/33
Filed: 1991-08-12
Abstract: 2.1. D-(-)-Pantolactone is an important intermediate in the synthesis of D-(+)-pantothenic acid or D-panthenol and can be obtained from the racemic compound by elaborate racemate resolution methods in the form of pantoic acid salts with chiral auxiliary bases and subsequent resolution of the pairs of salts with subsequent cyclisation of the pantoic acid. Since this synthesis is very elaborate, the object of the present invention is to provide a more suitable intermediate for pantolactone synthesis, which is to be obtainable straightforwardly and at low cost. 2.2. Such an intermediate is D-2,4-dihydroxy-3,3-dimethylbutyronitrile in an optical purity (D:L) of at least 80:20. D-(-)-pantolactone can be prepared in high yields by hydrolysis of the nitrile with concentrated acids. The nitrile is obtainable by reaction of hydroxypivalaldehyde with hydrogen cyanide in the presence of relatively large amounts of a D-oxynitrilase. 2.3. Preparation of D-(-)-pantolactone and D-(+)-pantothenic acid.

Patent DE-4207072-A1 (DE)
Inventor: MEYER HELMUT
IPC: G01G19/18
Filed: 1992-03-06
Abstract: The pile-lifting apparatus (2) at the feeder or delivery side of a sheet-fed printing press is incrementally adjusted in height by means of a brushless direct-current motor. The motor drives a shaft (6) and thus chains (7) to raise or lower the table (3) carrying a pile (4) of sheets, in accordance with the number of sheets in the pile, under the control of apparatus (8). After an interruption in the commutation sequence of the brushless direct-current motor, a progression to the following commutation phase is initiated. The weight of the movable object i.e. the pile is determined from the difference obtained between one of the motor variables with load and the specified motor variable without load. There is no need for an otherwise customary additional measuring apparatus for determining the weight of the pile (4). The variable may be a characteristic of the amount drawn by the motor, or the angle through which the rotor is moved at a fixed current. <IMAGE>
