Abstract: L'invention est relative à une méthode de trempe interrompue des alliages d'aluminium à durcissement structural. Elle comprend, à partir de la mise en solution : a) un refroidissement rapide, par trempe jusqu'à ce que le produit atteigne une température comprise entre 150° et 260°C. b) un arrêt de la trempe pendant quelques secondes à quelques dizaines de minutes (refroidissement à l'air) c) une reprise de la trempe jusqu'à la température ambiante. Dans ces conditions, on obtient des produits trempés revenues qui présentent des caractéristiques mécaniques voisines de l'état T6 et supérieures à celles de l'état T73 classique, avec une très bonne résistance à la corrosion (feuilletante ou sous tension) et un niveau de contraintes internes divisé sensiblement par 2 par rapport à l'état T6 classique.

Abstract: Système compatible de télévision permettant le codage de deux sources vidéo (VA, VB) d'informations d'images de télévision en couleur, comprenant une paire indépendante ou stéréoscopique d'images en temps réel. Une première source vidéo fournit un premier signal vidéo et une deuxième source vidéo fournit un deuxième signal vidéo en synchronisme dans le temps avec le premier signal vidéo. Le procédé de codage produit un signal vidéo composite (VE) de manière qu'un récepteur de télévision standard peut reproduire les images correspondant à la première source vidéo. Un récepteur de télévision non standard, c'est-à-dire un récepteur pourvu de circuits de décodage du deuxième signal vidéo, peut reproduire les images correspondant à la deuxième source vidéo et/ou les images correspondant à la première source vidéo. Le moyen de reproduire les images correspondant à la première source vidéo est fourni par un canal vidéo standard comme dans le récepteur de télévision standard, et ne nécessite aucun décodeur.

Abstract: Method for demodulating FSK signals in which zero crossings of the FSK signals are detected and processed further. A FSK demodulator including an address-generating logic and a memory connected to the address-generating logic. The FSK signals are delivered to the input side of and control the address-generating logic. At a system clock frequency, the necessary address sequence is supplied to the memory for reading out a pulse reply from the memory for each zero-crossing of the FSK signal. In the memory are stored time-sequential values of a pulse reply having a given duration which emulate the output of a digital non-recursive transversal filter having lowpass transfer characteristic upon an input pulse of given duration. The address generating logic supplies a definite counting address to each zero crossing on the input side which is not yet assigned to another zero crossing. The counting address sequentially assumes all sequence values for the given duration which are necessary for reading out the pulse reply from the memory and which last sequence value assumes a rest value after the completion of the read out process. Data read out from the memory during a given system clock period is summed up.

Abstract: Système et procédé permettant de positionner avec précision un organe transducteur (24) en alignement radial avec une piste de données sélectionnée sur un disque magnétique (22) en utilisant une commande par microprocesseur (54) et permettant de sauvegarder son alignement axial. Des servo-pistes divisées en secteurs (30), entremêlées radialement avec des pistes de données sur un disque magnétique, sont codées d'une manière unique à l'intérieur de groupes, le code comprenant l'emplacement des servo-signaux enregistrés à une première ou à une deuxième position à l'intérieur d'une pluralité de blocs de données situés sur les servo-pistes. Les servo-signaux enregistrés sont détectés par un transducteur (24) et comparés à une tension continue dans un comparateur (44) afin de produire une série d'impulsions d'horloge pour un registre à décalage (46). Une séquence prédéterminée d'impulsions correspondant aux emplacements possibles pour les servo-signaux enregistrés à l'intérieur du bloc de données dans un secteur (30) constitue la sortie de données vers le registre à décalage (46). La sortie du registre à décalage (46) est un nombre binaire correspondant à la servo-piste ou à la piste de données avec laquelle l'organe transducteur (24) est aligné radialement. Ces informations sont traitées pour identifier l'emplacement radial de l'organe transducteur (24). Un microprocesseur (54) détermine à partir de ces informations la séparation radiale entre l'organe transducteur (24) et la piste de données sélectionnées et produit en cas de besoin un signal provoquant le déplacement radial du transducteur (24).
