Abstract: A highly efficient dry sorter (1) for continuous operation has a conveyor be lt cover (4) with longitudinal grooves, with the corresponding conveyor surface arranged obliquely in such a way that the coarser coal runs off over the grooves while the fine st coal or substance remains in them. It is thus possible for the finest coal to be extracted from the top while the coarser granules are removed by the lower longitudinal side. T he belt conveyor (2) is given the necessary permanent tilt by the fact that to the underside (16) of the conveyor belt cover (4) are allocated edge supporting strips (17,19) designed to correspond to supporting rollers (22,23) arranged at a distance along the bearing frame (3). These supporting rollers (22,23) are supplemented by pressure rollers permitting the even securing of the edge region on both the upper and the lower longitudinal sid e (20). Dry fine coal is sorted with a high throughput rate and can be further processed  without any drying, thus giving rise to the minimum outsize quantities, as tests have shown.

Title: Dispositif d'impregnation de bandes en materiau poreux
Inventor: DUERR WOLFRAM
IPC: D21H23/32
Filed: 1995-07-31
Granted: 2001-07-17
Abstract: Dans des dispositifs connus d'imprégnation sous pression, une chambre qui se rétrécit en continu dans la direction de transport se situe entre un rouleau entouré par la bande à imprégner et la paroi intérieure d'un bac qui contient le milieu d'imprégnation. Le milieu d'imprégnation est amené à la chambre sous une haute pression qui augmente davantage dans la chambre par des effets dynamiques. Cette haute pression cause des problèmes d'étanchéité aux fentes d'admission et d'écoulement, ainsi qu'au niveau des côtés frontaux du dispositif. Le fonctionnement du dispositif peut être perturbé par des peluches qui se détachent de la bande de papier ainsi que par le milieu d'imprégnation qui pénètre entre les surfaces de glissement. L'invention vise à réduire ces inconvénients. Dans un nouveau dispositif, les garnitures d'étanchéité ont des fentes alternativement étroites et larges (12, 23, 24), à la manière de garnitures d'étanchéité à labyrinthe. Les rainures (12, 23, 24) sont pourvues d'orifices d'écoulement (14, 25, 26) du milieu d'imprégnation qui les traverse.

Abstract: Un système de communications multiplex à division des longueurs d'ondes comprend un poste de tête (2) et une pluralité de terminaux 1 interconnectés par un câble de fibres optiques (3). Le poste de tête (2) émet des longueurs d'ondes modulées en ondes continues (.lambda.¿1?-.lambda.¿k?) et une longueur d'onde de signalisation (.lambda.¿0?) utilisée pour indiquer, dans chaque créneau temporel, les longueurs d'ondes disponibles pour l'émission dans le créneau temporel suivant. Chaque terminal (1) est conçu de façon à recevoir la longueur d'onde de signalisation, à déterminer à partir de celle-ci le fait que le créneau temporel suivant contiendra ou non des paquets de données pour ce terminal et, si oui, à recevoir ces paquets. Le terminal (1) est conçu de telle sorte que, s'il doit émettre un paquet de données, il détermine à partir de la longueur d'ondes de signalisation le fait que le créneau temporel suivant contient ou non déjà des paquets de données pour le poste destinataire et, si oui, évite la collision de données en n'émettant pas son propre paquet de données. Le terminal (1) détermine ensuite une longueur d'ondes libre (.lambda.¿q?) à partir de la longueur d'ondes de signalisation (.lambda.¿0?), module la longueur d'ondes libre avec le paquet de données qu'il doit transmettre, et modifie la longueur d'ondes de signalisation.
