Granted: 2008-01-29
Abstract: L'invention concerne un implant (22) amovible pour disques, à centre élargi, destiné à la stabilisation de vertèbres cervicales (16, 18) adjacentes. Cet implant présente une section transversale sensiblement rectangulaire avec une hauteur (H) minimale et une largeur (W) supérieure à la hauteur. L'implant est monté amovible sur un applicateur en vue de son insertion dans la région anatomique entre deux vertèbres cervicales adjacentes dont on a enlevé le disque intervertébral, et, une fois introduit, l'implant est positionné par un mouvement d'avant en arrière dans l'espace discal de manière que la partie centrale élargie, de largeur plus grande, et les parties terminales de diamètre plus petit de l'implant, entrent en contact avec les corps des vertèbres adjacentes, l'implant étant ensuite tourné pour amener les côtés de l'implant de forme rectangulaire, définissant la largeur de l'implant, avec sa dimension (W) plus large, à s'engager avec les corps des vertèbres adjacentes. Un dispositif de verrouillage, sous la forme d'un barre de stabilisation (29), est ensuite fixé sur l'implant pour l'empêcher de continuer à tourner. La barre de stabilisation comprend une structure empêchant un mouvement de rotation relatif entre la barre de stabilisation et l'implant, ainsi qu'une structure faisant saillie dans l'espace entre les vertèbres cervicales pour empêcher un mouvement de rotation par rapport aux vertèbres.

Patent CA-2300083-C (CA)
Title: Propylene oxide purification
Inventor: RUETER MICHAEL A
IPC: C07D301/32
Filed: 1998-07-27
Granted: 2008-04-22
Abstract: Propylene oxide obtained by an epoxidation process which uses methanol as a solvent may be effectively treated to remove acetaldehyde by subjecting the crude epoxidation reaction product to fractional distillation. The methanol solvent is utilized during such distillation to lower the relative volatility of the acetaldehyde impurity, thereby making it possible to obtain a bottoms fraction containing substantially all the acetaldehyde. Purified propylene oxide having a reduced acetaldehyde concentration is removed as an overhead stream.  Water may also be effectively separated from the propylene oxide using this procedure.

Abstract: A cooling apparatus for a fuel cell system having high cooling efficiency. The cooling apparatus includes a chemical heat pump circuit using isopropyl alcohol, acetone, and hydrogen gas as a heat carrier. The chemical heat pump circuit includes an endothermic device incorporated in the fuel cell and an exothermic device for releasing heat from the circuit. The temperature of a heat carrier is increased to a first temperature by the heat of the fuel cell. The chemical heat pump circuit uses the heat of the heat carrier after it is heated to the first temperature to heat the heat carrier to a second temperature, which is higher than the first temperature. The heat of the heat carrier is used for other useful purposes or is simply desorbed. After the heat carrier is heated to the second temperature, the heat carrier is easily cooled by a cooling fan. Thus, the cooling apparatus has a high cooling efficiency.
