Abstract: Un circuit d'asservissement permet de commander electroniquement le fonctionnement d'un moteur electrique (100). La frequence de rotation du moteur est convertie en une forme d'onde de frequence variable par un tachymetre (115, 120). La sortie du tachymetre est appliquee sur un circuit de conversion qui comprend un detecteur de crete (125) qui convertit la forme d'onde de sortie du tachymetre (115, 120) en un signal d'ondes carrees. Le signal d'ondes carrees est, a son tour, applique a une entree d'une porte OU exclusif (150). Le signal d'ondes carrees du detecteur de crete est egalement applique a un registre a decalage (140) qui, apres une temporisation, applique le meme signal a une autre entree de la porte OU exclusif (150). Avec ces connexions, la porte OU exclusif (150) produit une sortie d'ondes carrees dont le cycle de travail est proportionnel a la vitesse du moteur a courant continu. Cette sortie peut alors etre amplifiee et appliquee directement au moteur electrique (100) pour l'entrainer, ou integree et appliquee dans un amplificateur (180) pour entrainer le moteur (100) selon des techniques d'asservissement standard.

Granted: 1989-08-09
Abstract: Un explorateur optique pour un systeme de tracage pour l'exploration d'une configuration irreguliere bidimensionnelle (13) utilisant un principe de deflexion de rayon optique. Une tete d'exploration (12) est montee de maniere non rotative au-dessus de la configuration sur un chassis (23) mobile dans deux directions coordonnees. L'image d'un element photosensible (30) montee sur la tete d'exploration est reflechie sur la configuration par un miroir pivotant (34) dans la tete d'exploration et est deflechie a frequence elevee dans les deux plans orthogonaux par l'interaction d'une paire d'electro-aimants perpendiculaires entre eux avec un aimant permanent (67). La paire d'electro-aimants consiste en des bobines perpendiculaires entre elles (68, 72) enroulees autour d'un noyau (69). L'axe geometrique (78) du miroir effectue une nutation autour d'un axe d'exploration pour obtenir une image d'exploration circulaire sur la configuration de l'element photosensible. L'axe autour duquel le miroir effectue une nutation, appele axe d'exploration, peut etre decale a partir d'un axe de reference fixe (35) pour obtenir des ecarts pour l'image d'exploration et produire a la fois des ecarts en avant et des ecarts "de coupe" perpendiculaires aux ecarts en avant. Un circuit de commande envoie des signaux alternatifs dephases a deux bobines pour provoquer ce mouvement de nutation du miroir. Le decalage de l'axe de nutation par rapport a l'axe de reference est effectue par application de signaux a courant continu sur ces bobines.

Title: Apparatus for keeping the tension of metal strips at a constant level
IPC: B65H23/10
Filed: 1983-03-02
Granted: 1986-07-16
Abstract: Strip processing lines require tension or back tension to be applied to the strip, as the case may be. These requirements are best met by the proposed chain bridle. The recoiling of adjacent slit strips on a tension reel will result in varying rewinding speeds and tensions due to the different thickness of the individual strands. Thick strands will be rewound too tight and thin strip too loose. Therefore, the chain bridle is installed before the tension reel to keep the tension of the various strands or a wide strip at a constant value. The strip (1) is clamped between two circulating chain systems (4a,4b), one arranged below and the other above the strip passline. One chain system (4b) is fixed, the other one (4a) is adjustable. The chain segments (4) of the chain systems (4a,4b) are provided with a covering and are moved parallel to the strip (1) through support rolls (5) and guide gibs (6a) with entry and exit guide curves (6) with the latter ensuring an adequate clamping pressure of the relevant opposite chain segments (4). The segment covering (7) may consist of an elastic coating (11) provided with additional shapes or profiled surfaces (12).
