Abstract: L'invention concerne un moteur électrique à haut rendement comprend généralement un composant magnétique métallique amorphe en vrac se présentant sous forme polyédrique. Dans ce composant, une pluralité de couches de bandes de métal amorphe sont laminées afin de former une partie généralement tridimensionnelle de forme polyédrique. Le composant magnétique métallique amorphe en vrac peut comprendre une, de préférence, deux surfaces arquées opposées l'une à l'autre. Ce composant magnétique peut être activé à des fréquences comprises entre environ 60 Hz et 20.000 Hz et présente (i) une perte dans le fer inférieure ou environ égale à 1 watt par kilogramme de matière métallique amorphe, lorsqu'il est activé à une fréquence d'environ 60 Hz et à une densité de flux d'environ 1,4 Tesla (T); (ii) une perte dans le fer inférieure ou environ égale à 20 watts par kilogramme de matière métallique amorphe, lorsqu'il est activé à une fréquence d'environ 1000 Hz et à une densité de flux d'environ 1,4 T et (iii) une perte dans le fer inférieure ou environ égale à 70 watts par kilogramme de matière métallique, lorsqu'il est activé à une fréquence d'environ 20.000 Hz et à une densité de flux d'environ 0,30 T. Les caractéristiques de rendement du composant magnétique métallique amorphe en vrac selon l'invention sont sensiblement meilleures en comparaison avec les composants en acier silicieux activés dans la même plage de fréquence.

Abstract: The invention relates to a reflector with high total reflection which is resistant to mechanical stresses. Said reflector comprises a reflector body and superimposed thereon a) a functional coating such as a varnish, b) a reflecting layer structure composed of a reflecting metallic layer and optionally arranged thereon one or several transparent ceramic layers, for example layers having an optical depth of .lambda./2. The reflecting layer structure contains, as its surface layer, a protective layer. Said protective layer is a silicon oxide of general formula SiOx, wherein x is a number from 1.1 to 2.0, or it is aluminum oxide of formula Al2O3, in a thickness of 3 nm or more. The protective layer protects the underlying layers from mechanical damages. In the DIN 58196 abrasion test the protected surface does not show any damages after 50 test cycles with 100 abrasion strokes. The inventive reflectors are used in illuminating or lighting engineering as reflectors for lights for workstations, primary lighting, secondary lighting, graticule lighting, luminous ceilings or as light reflecting lamellae.
Patent CA-2352889-A1 (CA)
Inventor: OLGUS LARS
IPC: H04L47/56
Filed: 1999-12-01
Abstract: In a point-to-multipoint link traffic is transmitted in packets across the shared medium. Access to the medium is controlled by permits sent by a central node to multipoint nodes in response to a queue record of the number of packets awaiting transmission at the multipoint nodes. When circuit emulated traffic, or traffic with tight delay and delay variation requirements, is to be sent across the link, permits are sent by the central node unsolicited at regular intervals in accordance with information stored in a scheduler. The scheduler may be a single or several circular memories comprising cells representing time slots on the link. The cells contain scheduling information corresponding to one or more multipoint nodes. The central node consults the scheduler to determine if a permit is scheduled. If no permit is scheduled the time slot may be allocated to an unscheduled service on the basis of a queue record.

Title: Reseau a division optique utilisant un diviseur de faisceau a polarisation a taux d'extinction eleve
Inventor: LIU JIAN-YU
IPC: H04Q11/00
Filed: 2000-06-02
Abstract: Selon cette invention, un multiplexeur à insertion-extraction de longueur d'onde optique assure la communication entre deux liaisons optiques qui prennent en charge le multiplexage par répartition en longueur d'onde (MRL). Un diviseur de longueur d'onde sépare spatialement le signal d'entrée en deux ensembles de canaux. Un filtre optique tel qu'un filtre d'interférences sépare spatialement un sous-ensemble de canaux d'entrée en une structure de canaux séparés. Une structure de commutateurs optiques programmable à insertion-extraction achemine sélectivement les canaux depuis les ports d'entrée vers une structure de ports d'extraction, substitue les canaux d'une structure de ports d'insertion aux canaux extraits et achemine les canaux d'entrée restants et les canaux insérés vers une structure de ports de sortie. Les canaux provenant des ports de sortie de ladite structure de commutation à insertion-extraction sont ensuite combinés puis transmis dans la deuxième liaison optique. Dans un autre mode de réalisation, on utilise un filtre d'extraction à circulateur constitué d'un circulateur optique et d'une série de réseaux de Bragg de filtrage pour sélectionner une série prédéterminée de canaux d'entrée devant être traités par la structure de commutation à insertion-extraction, le filtre d'extraction à circulateur laissant passer les canaux restants comme des voies rapides.

Title: Method for transferring cryogenic liquids and associated cryogenic fill nozzle insulating boot
Inventor: CHAMBERS SAMUEL DOUGLAS
IPC: F17C13/10
Filed: 2002-04-02
Abstract: The present invention discloses a method of transferring cold substances through a nozzle with moving parts. Also, an insulating boot is disclosed for helping to effect the method.      Generally, the method is for use in transferring cryogenic substances such as during the refueling of liquid natural gas vehicles. The present method causes an insulating layer to be created between a removable boot and a nozzle separating the ambient environment from the moving parts of the nozzle, purging the layer with a dry gas such as nitrogen to remove moisture and restricting the incursion of such moisture from the layer and therefore, from the moving parts to avoid freezing up of the moving parts. The layer may also used to help avoid freezing up of the abutting interface created between the nozzle and receiving line when the nozzle is removably engaged to a receiving line.

Title: Knock-on sweep structure and tools therefor
Inventor: RUCKLE JARROD RAY
IPC: A01B35/22
Filed: 2002-07-31
Abstract: Sweep retaining structure includes a spring wire retainer with a base supported in a groove on the underside of the wedge support which mates with a stem portion of the sweep. The wedge support is apertured, and a central curved portion of the retainer passes through the aperture and supports a sweep-contacting end above the surface of the wedge support. The end is biased toward a contact area on the sweep to engage the area and eliminate sweep loss problems by preventing the sweep from slipping downwardly from the mounted position. To remove the sweep, a tool is inserted through the slot to depress the retainer end, and the sweep is forced off the wedge support. A raised area on the sweep directs soil away from the retainer and contact area to reduce wear and eliminate depression of the end during operation. The underside of the raised area positions the wire end and provides bend-resisting support for the wire.
