Patent WO-2004020717-A1 (WO)
Inventor: KRUMM VALENTIN
IPC: D03D51/02
Filed: 2003-07-18
Abstract: L'objectif de l'invention est de configurer le démarrage et l'arrêt de systèmes d'entraînement séparés, destinés à des métiers mécaniques et à des mécaniques d'armure, de façon à réduire le plus possible et/ou à égaliser les courants ou les puissances électriques nécessaires, tout en conservant un niveau de fiabilité élevé sur le plan de la technique de régulation et du fonctionnement. Cet objectif est atteint, pour la phase de démarrage, de la manière suivante : le métier mécanique fonctionne tout d'abord dans un mode lent, à partir d'un moment de démarrage (t2) qui peut être fixé avant ou après le moment de démarrage (t1) de la mécanique d'armure ou au même moment que ce dernier. La mécanique d'armure subit une accélération pour parvenir à la vitesse de rotation de service, l'accélération dépendant uniquement du système d'entraînement. Le métier mécanique quant à lui passe brutalement du mode lent à la vitesse de rotation de service lorsqu'une valeur de position, de vitesse de rotation ou de couple de rotation, ou un instant (t3) prédéterminés sont atteints. Pour la phase d'arrêt, on procède de manière inverse : le métier mécanique est freiné brutalement pour passer en mode lent et pour pouvoir s'arrêter à un moment (t11), qui peut être fixé avant ou après le moment d'arrêt (t12) de la mécanique d'armure ou au même moment que ce dernier. La mécanique d'armure est freinée de manière plus lente que le métier mécanique qui, lui, subit un freinage tout d'abord brutal. Dans un mode de réalisation préférée de l'invention, il est possible de configurer le démarrage de la mécanique d'armure de façon prédéterminable ou sous le contrôle du système d'entraînement, de sorte que la vitesse de rotation de service, nécessaire au fonctionnement, dans la trame de départ, soit atteinte à un moment ultérieur par rapport au moment du coup de peigne du métier mécanique, et l'arrêt de la mécanique d'armure s'effectue avant l'arrêt du métier mécanique (après le coup de peigne).

Inventor: VENKATASUBRAHMANYA SRINIVASAN
IPC: H04L1/00
Filed: 1969-09-12
Abstract: 1,274,706. Error correcting system. R.C.A. CORPORATION. 10 Sept., 1969 [12 Sept., 1968], No. 44608/69. Heading G4A. The invention relates to an error detecting and correcting system. An n bit word is arranged into k blocks each having a check bit and a word composed of the blocks is transmitted serially or in parallel. To form the blocks the n bit word is arranged into k subsets S 1 -S k , where k must be a prime number. The subsets form the rows of a matrix whose ith column is X (i-1)t+1 , X (i-1)t+2 ,...X it 0,0,0, X it  ... X (i-1)t+1  cyclically shifted i-1 positions, where t=(k-3)/2 e.g. for n=14, k=7, t=2. A parity bit aj is formed for the jth subset of the matrix e.g. a 1  = X 1 #X 3 #X 6 #X 14  where # = exclusive OR and is inserted in the position occupied by the centre 0 in each row as shown in brackets in the matrix. Digits to form k blocks B1-k to be transmitted are obtained from the columns of the matrix such that B 1 =X 1 X 2 A 4 , B 2 =X 3 X 4 A 5 , B 7  = X 13 X 14 A 3  so that each block contains three digits from three different subsets. The blocks are transmitted and when received are used to form a syndrome Z = Z 1 Z 2 Z 3 ...Z 7  formed by the modulo 2 summation of the digits in each subset formed from the received words. If the words are correct each Z i =0 and Z i =1 only if an odd number of received S i  is in error. If an information bit in a single block is wrong the syndrome Z will include a pair of "1"s. If a check bit in the block is wrong Z will have a single 1 and the position of the "1" or "1"s will indicate the faulty bit e.g. if B 1  is incorrect Z=e 1  1  e 2  1  0 e 3  1  0 e 2  1  e 1  1  where e is "1" if the corresponding received x or a is wrong. Since the pattern is symmetrical and a similar pattern cyclically shifted will apply to the other blocks B 2 -B 7  an analyser can be used to check the pattern, e.g. Z 1  = (Z 1 #Z 7 ) + (Z 2 #Z 6 ) +Z 3 +Z 5 =0 thus if d 1 =Z 1 , d 1  = 1 only if the symmetry pattern is as above or all zeros. A similar pattern cyclically shifted holds for the other values. If the error is correctable then exactly one of the d's is a "1". If more than one "1" is present there is an error in one or more analysers. If all the d's are zero then the error is not correctable. In binary operation the bit identified by the syndrome pattern is complemented to correct the error. If k = 19, B=8 which is a common size of a byte in computers.

Title: Cct. for production of harmonics from fundamental pulse - has push-pull with two transistors of opposite conduction
Inventor: PILZ RUDOLF
IPC: H03B19/14
Filed: 1973-10-12
Abstract: The circuit has an output transformer whose primary winding centre tapping is connected through a capacitor to a supply voltage terminal. Its secondary side is in the form of an oscillating circuit. The transistors' inputs are connected through their own differentiating circuits to a generator delivering the fundamental frequency pulses. A capacitor of one differentiating circuit has a trimmer for adjustment to the frequency to give better characteristics. A capacitor ensures that both transitors bear the same load. A change of the differentiating component effects mainly the curve shape and thereby the phase condition of the impulses. In this way the unavoidable wandering from the ideal rectangular potential is in effect compensated.
