Abstract: The bollard consists of an upper part (1) and of a base part (4) let into the ground (3). The upper part (1), which is equipped with lighting elements (2), may be readily pushed away or hurled away by a vehicle ramming into it. The electrical supply for the lighting elements (2) is provided by means of an inductive coupler (10) having an iron core which is divided into two halves (7, 12). One core half (11) carries the primary winding (13), which is connected to a cable, and is fixed to the base part (4). The other core half (12) carries the secondary winding (14), which feeds the lighting elements (2), and is fixed to the upper part (1). After the upper part (1) has been rammed, it is possible for a non-specialist in electrical installations to fix a replacement upper part (1) onto the undamaged base part (4). <IMAGE>

Abstract: Pour obtenir une liaison guidée entre le ressort de contact et le support de couplage lors de la fabrication de supports de couplage avec contacts à ressort pour semiconducteurs constitués par un support en plastique, un manteau en métal introduit dans le support et des ressorts de contact introduits dans le manteau on propose ce qui suit: chaque ressort de contact avant son introduction dans le manteau, lui-même introduit dans le support, respectivement chaque manteau muni de ressort de contact introduit dans l'ouverture de réception du support relative à la partie du manteau fixe par rapport au support, sont tournés autour de leurs axes longitudinaux dans un but d'alignement. Ainsi la position par rapport à la branche du ressort et du canal polygonal formé est identique pour chaque pièce de ressort à contact introduite qui suit la pièce et pour celle qui la précède. La partie en ressort de contact qui est guidée lors de la rotation et lors du guidage assure au moins temporairement sa position relative en liaison forcée avec le manteau.

Title: Thermostat numerique pourvu d'une protection contre les interruptions d'alimentation
Inventor: HENDRICKS DONALD B

Abstract: Un thermostat numérique (10) à micro-ordinateur est alimenté par une tension d'alimentation provenant d'un condensateur d'alimentation en tension (124) de capacitance élevée (par exemple 3,3 farad). Le condensateur d'alimentation en tension (124) est chargé normalement par une tension à courant alternatif provenant de la chaudière et qui est redressée par un pont redresseur biphasé (126). Les données relatives au temps et à la température sont stockées dans une mémoire à accès sélectif permettant la lecture et l'écriture (79). Le micro-ordinateur (48) commande le fonctionnement du thermostat (10) en fonction de la température détectée et des données concernant le temps et la température. Un circuit détecteur de tension (136) détecte la tension d'alimentation provenant du condensateur d'alimentation en tension (124) et coupe la tension d'alimentation du micro-ordinateur (48) et d'autres parties du circuit de commande du thermostat lorsqu'une interruption prolongée de l'alimentation à courant alternatif provoque une diminution jusqu'à une valeur prédéterminée de la tension d'alimentation. Celle-ci continue à être appliquée à la mémoire à accès sélectif de lecture/écriture (79) de manière à sauvegarder les données relatives au temps et à la température. Lorsque l'alimentation à courant alternatif est rétabli et lorsque le condensateur d'alimentation en tension (124) est rechargé, le thermostat numérique (10) est prêt à reprendre son fonctionnement sans que l'utilisateur ne doive réintroduire toutes les données stockées relatives au temps et à la température. La capacitance du condensateur d'alimentation en tension (124) est suffisamment grande pour permettre au condensateur (124) de délivrer le courant nécessaire pour sauvegarder les données relatives au temps et à la température stockées dans la mémoire à accès sélectif (79) pendant des interruptions prolongées de courant, sans avoir recours à un accumulateur d'appoint.

Abstract: Des fibres à mode et polarisation uniques sont produites en introduisant le phénomène d'anisotropie dans une fibre optique de géométrie autrement arbitraire et de profils d'indice de réfraction arbitraires mais de guidage. Le phénomène d'anisotropie qui peut être induit par l'application de contraintes transversales à la fibre optique est suffisant pour établir des conditions dans lesquelles un mode de lumière polarisé linéairement "fuit" de la fibre. Dans le cas de fibres optiques à profil en gradin ayant un noyau (10) et un revêtement (11), le phénomène d'anisotropie peut être tel qu'un mode de propagation de la lumière est complètement éliminé de la fibre. Dans une alternative, dans de telles fibres, le phénomène d'anysotropie peut être tel que la fuite du mode indésiré de la fibre est progressive, de telle sorte que la fibre atténue effectivement ce mode, éliminant ainsi la propagation de ce mode lorsque la fibre possède une longueur suffisante.
