Abstract: An alarm system is capable of monitoring a plurality of zones (1-8). The system comprises a sensor module (7) in each zone, connected to an alarm sensor (1-6) and by a respective signalling path (8) to a central controller (9). Alarm indications produced by the alarm sensor can be stored in the module and an indication of the type of alarm indication can be signalled to the controller. The controller is able to act on the module to set or unset settable alarm sensors, and also to produce a visual indication in the zone of the module being an indication of the ability of a module to respond to alarm indications. 
     The sensor modules can also be connected in series and can monitor more than one alarm sensor.

Abstract: To avoid using the throttle control of turbo motor compressors for, for example, heat pumps, freezers and air conditioning units, which is usually associated with high losses and unwanted mains reactions, thyristor-controlled or transistor-controlled link converters for a variable output frequency and voltage are provided for controlling the speed of the electric motor 1. In this arrangement, the shaft 11 of the turbo motor compressors is magnetically or gas-dynamically or hydrostatically contactlessly supported in magnetic bearings 12, 13, 14 or gas-dynamic sliding bearings or hydrostatic gas bearings. As a result, no oil from the roller or sliding bearing normally used comes into contact with the working medium, for example a coolant, and a resultant disadvantageous influencing of the working medium, on the one hand, and of the bearing of the shaft 11, on the other hand, is reliably eliminated. In addition, all devices and monitoring systems required for the oil lubrication of the sliding bearings are omitted and the maintenance expenditure for the bearings 12, 13, 14 can be considerably reduced. <IMAGE>

Abstract: Procédé de fabrication de produits de polyester renforcé par des fibres de verre. On prépare un produit composite de renforcement et de résine prêt au moulage en utilisant un initiateur qui a été micro-encapsulé afin de prévenir la réticulation induite par l'initiateur des réactifs de la résine. L'initiateur est libéré pendant le moulage du composé par rupture des microcapsules en raison de la pression de vapeur interne développée à une température de moulage prédéterminée. L'encapsulation de l'initiateur provoque une amélioration de l'homogénéité et de la fluabilité des composés pendant le moulage et permet d'obtenir des produits de polyester moulés avec des degrés de polymérisation plus élévés et plus de surfaces finies exemptes de défaut.

Abstract: Système optique de stockage de données, utilisant un rayon laser (1) d'écriture modulé par les données et un rayon laser de lecture sans effacement de longueur d'onde prédéterminée. On décrit des supports optiques améliorés pour de tels systèmes, caractérisés par des couches multiples dont les caractéristiques optiques et l'épaisseur sont choisies pour s'adapter à une énergie d'écriture et de lecture et à une longueur d'onde prédéterminée, de manière à obtenir une condition d'"anti-réflexion" pour les parties non enregistrées du support et une réflectivité relativement plus élevée pour les parties enregistrées. Un support optique préféré comprend une couche d'aluminium très réfléchissante (c), une couche d'écartement en polymère relativement transparent (d) recouvrant la couche réfléchissante, et une couche optiquement absorbante (enregistrement) (e) recouvrant la couche d'écartement.

Abstract: Des marques de secteurs sont placées sélectivement dans chaque servo-piste grossière (M-15) du disque rotatif (10). Ces pistes concentriques de recherches grossières (11-15) préécrites sur le disque (10) sont utilisées par un servo-système pour le positionnement du mécanisme de lecture/écriture. Des moyens de lecture de pistes grossières détectent simultanément au moins deux pistes adjacentes de recherches grossières (54-55). Des moyens de détection (60) détectent la position relative de ces pistes de recherches grossières (54-55) dans la plage de détection des moyens de lecture de pistes grossières, et cette information concernant la position est utilisée par le servo-système pour commander sélectivement la position radiale des moyens de lecture de pistes grossières par rapport au disque rotatif (10). Les marques de secteurs écrites dans les pistes de recherches grossières (11-15) sont détectées de la même manière, et un signal est produit indiquant le début et la fin de chaque secteur. Un oscillateur (69) est verrouillé sur ce signal de secteur de sorte qu'un nombre fixe de cycles du signal de l'oscillateur correspond au passage d'un secteur du disque sous les moyens de lecture de pistes grossières. Un compteur (70) est ensuite utilisé pour compter le nombre approprié de cycles. Une marque de repère (30) représentant un point de référence de degré zéro est également placée dans la piste de recherche grossière (54). Lorsque la marque de repère (30) est détectée, elle remet le compteur (70) à zéro. Le comptage du compteur indique donc toujours la position de rotation (localisation de secteur) du disque (10).
