Patent CA-2419316-A1 (CA)
Inventor: HICHWA BRYANT
IPC: G02B6/35
Filed: 2001-03-16
Abstract: A bi-stable micro-machined electro-mechanical system ("MEMS") switch. In a preferred embodiment, the bi-stable MEMS switch is used in an NXN optical signal switching system. Spring arms act in conjunction with a hollow beam portion of a movable center body of the switch to accommodate strain in the arms as the switch is moved from a first position to a second position, thus avoiding buckling of the spring arms. Both the first and second switch position occur at local minimums of mechanical potential energy, thus providing two stable switch states. The center body is moved in relation to static portions of the switch by an actuator, such as an electro-static comb drive.

Abstract: L'invention concerne un procédé de raffinage d'un produit pétrolier pour extraire les hydrocarbures aromatiques et pour séparer les huiles paraffiniques et les cires paraffiniques. Le procédé fait appel aux équilibres de phase, selon lesquels des cires solidifiées ou cristallisées, normalement présentes dans le produit pétrolier, sont utilisées pour extraire des huiles d'une phase de solvant liquide contenant des hydrocarbures aromatiques dissous dans le produit pétrolier non raffiné. La cire contenant les huiles (26) est séparée du solvant contenant les hydrocarbures aromatiques, puis elle est traitée pour la séparation des cires et des huiles (28). Dans les produits pétroliers contenant peu de cire ou pas du tout, de la cire supplémentaire peut être ajoutée, puis recyclée en retour pour être utilisée ultérieurement dans l'extraction des huiles d'un produit pétrolier. Ce procédé offre une application particulière dans la préparation d'huiles lubrifiantes à indice de viscosité élevé, où la présence d'hydrocarbures aromatiques et de cire peut être nuisible.
