Abstract: Elément perméable au gaz comprenant une masse réfractaire poreuse au moins dans sa partie interne, placée dans un réceptacle métallique constitué par une enveloppe latérale obturée à l'une de ses extrémités, par un fond pourvu de moyens d'amenée d'un gaz de soufflage. L'invention consiste à équiper intérieurement le réceptacle métallique (2) d'un déflecteur (11), solidaire du fond (7) et dont les parois sont parallèles à l'enveloppe latérale 6, mais s'étendent sur une hauteur inférieure à celle de l'enveloppe (6), de manière à ne pas affleurer la surface libre (3) de la masse réfractaire (1). L'invention permet, d'une part, d'éviter que les infiltrations de métal en fusion entre l'enveloppe et la masse réfractaire se prolongent jusqu'à venir obturer les moyens d'amenée du gaz de soufflage (8) et, d'autre part, de canaliser les gaz à travers la masse réfractaire.

Abstract: A switchboard control system in which a plurality of switchboards are connected to a time division exchange and controlled by the time division exchange. A speech signal and a control signal (a signal of key information, display information, subscriber number information and other information necessary for the exchange operation by a switchboard operator), which are delivered and received by each switchboard and the time division exchange, are transmitted together by a common transmission line on a time-division-multiplexed basis. On the side of the switchboards are disposed a position controller, by which the signals are multiplexed and separated and the common transmission line and the switchboards are interconnected. For delivering and receiving the signals, a common channel signalling equipment is connected to the time division exchange and a remote common channel signalling equipment is provided in the position controller. Between these equipments, the control signal is transferred via the common transmission line and, between the remote common channel signalling equipment and each switchboard, it is transmitted via a control signal line constituted as a common bus separately of a signal line for the speech signal.

Abstract: Un système de traitement de signaux permet de traiter des signaux intelligents variant dynamiquement et représentés par des fréquences différentes en transférant ces signaux dans une bande passante plus étroite que la gamme des fréquences. Le système utilise un circuit compresseur (27) comprimant uniquement les signaux se trouvant dans une bande passante définie au préalable. Des circuits filtres actifs (35) façonnent les signaux comprimés en une enveloppe de puissance prédéterminée ayant des composantes de signaux de fréquence fondamentale et des éléments constituants en relation harmonique des fréquences fondamentales. Un autre circuit compresseur (37) est utilisé pour comprimer davantage les éléments constituants des signaux de l'enveloppe de puissance. Un agencement de réaction négatif (29) assure une limitation dynamique de la compression effectuée par le premier circuit compresseur (27) en fonction de l'augmentation de compression effectuée par le second circuit compresseur (37). Un dispositif combinatoire linéaire (57) est utilisé pour recombiner les éléments constituants en relation harmonique fournie par le second circuit compresseur et ainsi extraire et récupérer les signaux intelligents variant dynamiquement. Le système comporte un nouveau procédé de traitement de signaux qui consiste à définir en premier lieu une gamme d'éléments constituants de signaux d'origine à traiter comprenant des fondamentales de signaux et des composantes en relation harmonique de ces fondamentales puis à comprimer de manière essentiellement dynamique la gamme d'éléments constituants de signaux d'origine. Les amplitudes des composantes de signaux du signal comprimé dynamiquement sont commandées sélectivement pour définir une enveloppe de puissance qui est à nouveau comprimée dynamiquement pour obtenir des éléments constituants de signaux traités tout en assurant une limitation retardée de la compression des éléments constituants des éléments d'origine.
