Title: Rotation-symmetrical workpiece production method
Inventor: KOESTERMEIER KARL-HEINZ
IPC: B21D22/16
Filed: 1997-04-01
Abstract: Ring-shaped drawing dies (20) are pushed over the workpiece (10) from both sides of the headstock to reduce and form it into the external toothing (12) of the chuck (11) assisted by a pressure roller (13,14) acting on the workpiece, in this same setting. Before drawing the workpiece is wrapped round the chuck by the roller or pressed onto the chuck on the side adjoining the headstock. During drawing, grooves are formed in the workpiece exterior to radially oppose the bevel inner toothing produced by a drawing die (30) as this rotates relative the headstock. After drawing, the roller works the workpiece exterior. Chuck and headstock are revolved along with the workpiece. The inside diameter of die matches the outside diameter of the workpiece being formed and chuck and headstock can together adjust axially relative the die ring to push this over the work and form this accordingly.

Title: New antifungal derivatives of melithiazole C
Inventor: HOEFLE GERHARD PROF
IPC: A01N43/78
Filed: 1997-04-11
Abstract: Melithiazole compounds of formula (I) (R = COOC2H5) are obtained by reacting the corresponding known compound (II) (= compounds (I) where R = CONH2) with (C2H5)3OBF4.  Similarly compounds (III) (= compounds (I) where R = CONHCH3 or CON(CH3)2) are obtained by reacting the known compound (IV) (= compounds (I), where R = COOCH3) or (I) itself with methylamine/trimethyl aluminium or dimethylamine/trimethyl aluminium (which produce aluminium amides in situ).  C-3 keto compounds of formula (V) (R has any of the definitions given above) are produced by hydrolysis of any compound (I)-(IV) and conversion of the C3-enol ether group to a keto group.  C-4 stereoisomers of formula (VI) are produced by base-catalysed epimerisation of compounds of formula (V) at the C-4 atom, followed by regeneration of the C3 enol ether group. W = OCH3, OC2H5 or NR1R2; R1, R2 = H or CH3. Similarly, C-5 stereoisomers of formula (VII) are produced by acid-catalysed epimerisation of (V) at the C-5 atom, in which the OCH3 group is optionally exchanged for a 2-4C alkoxy group, followed by regeneration of the C3 enol ether group. X = 1-4C alkyl.  C11 keto group-containing compounds of formula (VIII) are produced by condensation of (VII) with a compound of formula H2Y. Y = NOR3 or N-NR4R5; R3 = H, 1-6C alkyl, aryl (especially phenyl) heteroaryl or benzyl; R4, R5 = H, 1-6C alkyl or aryl (especially phenyl); or R4+R5 = (CH2)4-6.  C-11 alkenyl derivatives of formula (IX) are produced by reacting (VII) with a Wittig or Wittig-Horner reagent. R6, R7 = H, 1-6C alkyl, benzyl or aryl (especially phenyl) or heteroaryl. C-11 derivatives of formula (X) are produced from (VII) by: (a) reduction with a complex hydride and optional alkylation or acetylation of the resulting OH group to produce (X), where Z = H, or (b) reaction with a metallo-organic compound and conversion of the addition product to give (X), where Z = 1-4C alkyl or aryl.  Also claimed are compounds (III), (VI), (VII), (VIII), (IX) or (X) (R = CONHCH3 or CON(CH3)2) produced by reacting the corresponding compounds (where R = COOCH3) with a methylamine/trimethyl-aluminium or dimethylamine/trimethyl-aluminium compound (i.e. an aluminium amide produced in-situ).  Also claimed are C-3 keto compounds (II), (III), (IV), (I), (VI), (VII), (VIII), (IX) or (X) with C3-oxo groups, produced by hydrolysing the corresponding precursors and converting the C3-methyl enol ether group to a C3-keto moiety.

Title: Estimator of sleepiness of vehicle driver from eyelid movement
Inventor: KUMAKURA SAE
IPC: B60W30/00
Filed: 1997-04-14
Abstract: The frequency distribution is established over a first time interval. The normal frequency range is found from the distribution, the median of the normal range is calculated and a threshold time is found by adding a predetermined value to the median. Thus a minimum threshold time for a blink is established so as to extract the slow blinks as a function of the distribution frequency.  A calculation module (30) calculates the ratio of the appearance of slow blinks to the total number of blinks during a second time interval subsequent to the first time interval. The ratio is put on a display (3) and is used by a sleepiness level discriminator (50) to give an alarm when the ratio exceeds a threshold.

Patent DE-19722368-A1 (DE)
Inventor: PAAP KARL-LUDWIG
IPC: A01K85/16
Filed: 1997-05-28
Abstract: For big-game fishing artificial baits are used. Such baits like a wobbling spoon and a blinker are usually pulled in water by the fisher in such a way that they imitate by their bowed shape the movements of real fish. The imitation of nature by certain baits, however, is often inefficient with careful fish. This is why the inventive artificial bait has a caudal fin (3) which can be actively actuated in one direction or the other by means of a pulling member (9) meshing with both flanks (12, 13). Owing to additional breaks in the movement and an elastic design of the caudal fin (3) a particularly misleading imitation of a true fish behaviour is obtained, resulting in optimal bait efficiency, including with big game.
