Title: Elements metalliques d'assemblage
Inventor: SIMMONS ANTHONY GRANT
IPC: B21D39/00
Filed: 1998-04-17
Granted: 2007-03-27
Abstract: L'invention concerne un procédé pour assembler des éléments forgés, usinés ou moulés à un tube métallique. Selon un autre aspect, l'invention traite d'un objet métallique construit selon ce procédé. Le tube est chauffé de manière à assurer la dilatation de son diamètre, mais en évitant qu'il ne soit recuit, c'est-à-dire, en évitant des effets défavorables sur ses propriétés mécaniques. Ainsi, pendant que le tube est encore chaud, il est poussé sur une partie de l'élément central de telle sorte qu'il vienne recouvrir une rainure circonférentielle ménagée dans l'élément central. Ainsi, pendant qu'elle est encore chaude, la partie circonférentielle du tube qui recouvre la rainure, est roulée pour pénétrer dans la rainure, et une fois refroidie, elle est fixée, par serrage, dans cette rainure. L'invention s'applique, mais non exclusivement, à la construction de roues de véhicules, comportant un moyen ou centre forgé, usiné, formé ou moulé et une jante métallique.

Title: Optimized fault notification in an overlay mesh network via network knowledge correlation
Inventor: LINDHORST-KO GWENDA
IPC: H02H3/05
Filed: 2001-10-03
Granted: 2009-12-22
Abstract: Failures within a communications network are compensated for by establishing a set of two or more communications paths across the network between a source node and a destination node. At the source node a status of each one of the set of communications paths is maintained, and the data traffic is load-balanced across those ones of the set of communications paths having an operational status. In the event of failure of a physical network resource, a failure notification message is propagated to the source node, which registers a non-operation status of each path traversing the failed resource. Load-balancing of the data traffic continues across the remaining operational paths. Traffic may be prioritized based on service level agreements and quality of service protection guarantees.
