Abstract: ABSTRACT        There is provided an optical external modulator that can modu-late the polarization of incident light without regulating the state of polarization of the light entering the modulator.  Such a modulator can be suitably incorporated into an optical telecommunications system.  An optical external modulator according to the invention comprises a sub-strate 1, an optical transmission line 7, a polarization modulating section 11 and a phase changing section 8 for changing the state of polarization of the light passing through the optical transmission line by applying stress to the optical transmission line 7 as a function of a modulation signal given to the modulator such that the phase difference between the X-component and the Y-component of the light being propagated through the optical transmission line 7 is shifted by (2m-1)*.pi./2 (m is a positive integer).

Title: Dispositif de commande au fond dans un puits de production et procede correspondant
Inventor: TUBEL PAULO
IPC: E21B47/06
Filed: 1996-02-09
Granted: 2008-01-29
Abstract: L'invention porte sur un dispositif de commande au fond dans un puits de production permettant de commander automatiquement des appareils au fond en fonction de paramètres de fond captés et sélectionnés. Cette invention présente cette particularité notable que l'autocommande est mise en marche au fond en l'absence d'un signal de commande initial en provenance de la surface ou émis par quelque autre source extérieure. Ce dispositif de commande comporte généralement des capteurs au fond, des dispositifs électromécaniques au fond et des circuits informatisés de commande au fond au moyen desquels les circuits de commande agissent sur les dispositifs électromécaniques d'après les données d'entrée provenant des capteurs au fond. De la sorte, en utilisant les capteurs au fond, le dispositif informatisé de commande au fond sera en mesure de surveiller des paramètres de fond réels (tels que la pression, la température, le débit, l'arrivée de gaz, etc.) et d'exécuter des instructions de commande lorsque les paramètres de fond sous surveillance sortent d'une plage sélectionnée de fonctionnement (indiquant, par exemple, des conditions dangereuses). Ces instructions de commande automatique amèneront un dispositif de commande électromécanique (comme une vanne) à mettre en marche un appareil approprié (manoeuvrer un manchon coulissant, par exemple, ou une garniture d'étanchéité ou fermer une pompe ou d'autres dispositifs d'écoulement de fluides). Le dispositif de commande au fond réalisé au titre de cette invention comporte également des émetteurs-récepteurs permettant une communication bidirectionnelle avec la surface ainsi qu'un dispositif de télémesure servant à établir des communications à partir du puits de production, en surface, vers un site à distance.

Title: Electrical switch and variable resistance module for vehicle brake pedal or accelerator and method of operation
Inventor: CRIPPEN RANDALL M
IPC: H01H21/28
Filed: 1997-02-05
Granted: 2000-05-23
Abstract: A method and apparatus for actuating an electrical switch and providing a variable electrical resistance usable to sense displacement of a movable member. The apparatus includes a housing for receiving the electrical switch, a variable resistance element and an actuator with a body member and a transverse cylindrical sleeve. An electrically conductive wiper is coupled to the actuator and contacts the variable resistance element, which varies with pivotal movement of the actuator. The body member is pivotably supported by an aperture of the housing about an axis of the cylindrical sleeve and a spring member biases the actuator toward an initial position, wherein the actuator is pivotable against the bias of the spring to actuate the electrical switch and to provide the variable resistance by positioning the electrically conductive wiper along the variable resistance element. A guide surface within the housing guides the actuator and the electrically conductive wiper in fixed relation relative to the variable resistance element when the body member is pivoted within the housing. The cylindrical sleeve protrudes through an aperture of the housing and is coupled to the movable member by a collar with a set screw without having to calibrate the variable resistor or the switch actuation timing.

Abstract: Cette invention concerne un procédé d'inhibition de la relaxation du spin nucléaire induite par une surface, et du piégeage en surface d'un gaz rare hyperpolarisé, de préférence du <129>Xe, à l'aide de surfaces recouvertes d'un polymère. Ce procédé consiste à inhiber la quantité d'interaction du gaz rare avec le revêtement polymère de la surface d'un appareil qui entre en contact avec ledit gaz rare. Ce procédé consiste de préférence à inhiber la relaxation du spin nucléaire d'un gaz rare en remplaçant au moins certains des protons dans le polymère par des substituants possédant un spin nucléaire différent de zéro et/ou une perméabilité aux polymères réduite. Le deutérium constitue un substituant préféré ayant un spin différent de zéro. Une modification préférée permettant de réduire la perméabilité consiste à introduire dans le polymère, un substituant tel qu'un halogène, et de préférence du fluor. L'invention concerne également des conteneurs possédant des surfaces qui ont reçu un revêtement de polymère inhibant le piégeage du gaz rare et la relaxation du spin nucléaire. En outre, cette invention concerne également des procédés permettant d'accroître la production et d'améliorer le stockage d'un gaz rare hyperpolarisé, en diminuant la relaxation du spin nucléaire et en limitant le piégeage du gaz rare dans le revêtement polymère d'un appareil contenant ledit gaz rare.
