Abstract: L'invention concerne un dispositif de communication tel qu'une carte d'identité personnelle se présentant sous forme d'un badge ou d'une étiquette portés sur l'extérieur des vêtements. Ce badge comprend une première couche de matériau (11) transparent comprenant une surface intérieure profilée en forme de motif répétitif rétroréfléchissant. Une seconde couche (12) également composée d'un matériau transparent comprend une surface interne profilée formant un motif rétroréfléchissant complémentaire. Un matériau (13) de cristal liquide dont l'indice de réfraction peut être modifié par l'application d'un champ électrique est intercalé entre les deux couches. Lorsque l'indice de réfraction de cette couche (13) de cristal liquide est proche de celui de la première (11) et de la seconde (12) couche, le rayonnement incident traverse le dispositif avec une diffusion faible. Toutefois lorsque l'indice de réfraction de la couche (13) de cristal liquide est modifié par l'application d'un champ électrique, le rayonnement incident est rétroréfléchi par l'interface profilée entre la première couche (11) avec la couche (13) de cristal liquide. Ce dispositif de communication est capable de rétroréfléchir la lumière incidente et de moduler le rayonnement en modifiant l'indice de réfraction de la couche (13) de manière que le faisceau réfléchi peut fournir une information à un récepteur. Ce système permet de transmettre une information dans un environnement de communication sans contact au moyen d'un dispositif ne nécessitant que très peut d'énergie de fonctionnement.

Abstract: An esophageal prosthesis (10) for preventing reflux of gastric fluids through the esophagus. The esophageal prosthesis process includes a tubular frame (11) with a sleeve (13) disposed around and longitudinally along the tubular frame as well as extending from the distal end (14) of the frame. The lower portion (28) of the sleeve has a readily collapsible lumen (15) that forms a one-way valve for preventing the reflux of gastric fluids in an antegrade manner through the esophagus. Fluids however readily flow through the sleeve in a antegrade direction. In response to a pressure build up in the stomach of a patient wanting to belch or vomit, the lower portion of the sleeve inverts through the passage (12) of the tubular frame, thereby relieving the pressure build up or voiding the patient's stomach. The tubular frame includes a plurality (19) of self-expanding zig-zag wire stents (20, 21, and 23) that maintain the patency of the esophagus and, in particular, the lower esophageal sphincter and any tumor that is causing stricture of the esophagus.

Le secteur cylindrique d'allumage (19), dans lequel une ouverture (24), placée sur l'un de ses cotés, communique avec l'enceinte de combustion (21), est disposé parallèlement au secteur de mélange (18). Des orifices de brûleur (25), qui se trouvent sur la limite existant entre le secteur de mélange (18) et le secteur d'allumage (19), constituent un réseau catalytique (25a). De ce fait et dans la mesure où la combustion catalytique se produit également sur le réseau catalytique (25a), après naissance d'une flamme en amont du catalyseur de combustion (22), chauffé par la chaleur émanant de la flamme et ce, afin d'élever la température jusqu'à ce qu'elle devienne une température susceptible d'assurer la combustion catalytique, la flamme part d'elle-même et le catalyseur de combustion (22) est alors en mesure d'amorcer la combustion. Cette combustion s'effectue en toute sécurité même si les parois de l'enceinte de combustion (21) sont minces. L'épaisseur du corps de catalyse peut être réduite sans porter préjudice aux caractéristiques de combustion et, partant, la hauteur du brûleur peut être réduite de façon à réduire également les dimension et l'épaisseur du dispositif de combustion catalytique.

Abstract: A process for the manufacture of alkanes comprising a cross-metathesis reaction between at least one starting alkane (A) and one organometallic compound (B) fixed to an inorganic support and comprising a metal bonded to at least one hydrocarbon-comprising radical. The reaction leads to the formation of at least one other alkane (C) which is a higher or lower homologue of the starting alkane (A), by cleavage of the hydrocarbon-comprising radical with the metal of the organometallic compound (B) and recombination of the radical with at least one other radical originating from a cleavage of the starting alkane (A). The metal of the compound (B) preferably is selected from transition metals, lanthanides and actinides, and the hydrocarbon-comprising radical of the compound (B) preferably is selected from alkyl, alkylidene and alkylidyne radicals.
