Abstract: The method of the invention relates to the individualised updating of a set of independent audible announcement transmitting systems, for example in stations, from a centralised system for recording and storing an audible data base, in digital form. According to the invention, the new audible data are recorded and they are stored in digital form in the data base of the centralised system, the data specific to an independent system are classified in a delimited area of the memory, the digitised audible data specific to an independent system contained in the said area are reproduced, for example on a diskette, and the audible data contained on the diskette are loaded into memory in the independent system in question. In preference, the data base of the centralised system contains phrases comprising variable parameters, and the operating system of the independent system assigns to each variable parameter characterised by a distinctive symbol, an elementary word or an set of elementary words, selected from the memory of the independent system on the basis of the nature of the parameter, of its distinctive symbol and the instructions from the operator.

Abstract: A modulator arrangement comprises two Mach-Zehnder modulators, a main modulator (2) and a compensation modulator (3) having non-linear transmission functions. The modulators (2, 3) are controlled by a modulating control signal (V), via electrodes (16, 17). A carrier wave (S1) from a laser (7) is power divided (a, 1-a) into part-waves in a power divider (5) between the modulators (2, 3). The modulated part-waves (S2, S3) are superimposed at an output (14) to produce a resultant modulated wave (S4). A linearized transmission function between the control voltage (V) and the power of the resultant modulated wave (S4) has a radius of curvature whose length is maximized within a control voltge range, so as to minimize intermodulation distortion. The mean slope of the transmission function is maximized within this range. At a common control voltage (V) for the modulators (2, 3), the modulator arrangement has an optimal transmission function at a length ratio b = √3:1 between the modulators (2, 3), and a power ratio between the part-waves of √3 :9. The main modulator (2) is the shortest and modulates the strongest part-wave.

Title: Integrated optics pockels cell voltage sensor.
Inventor: JAEGER NICOLAS AUGUST FLEMING
IPC: G01R1/067
Filed: 1991-01-31
Abstract: An integrated optics Pockels cell for use in a voltage sensor includes a crystal exhibiting the electro-optic effect in which an integratd straight line wave guide substantially aligned with a z axis of the crystal is incorporated. The wave guide has two substantially orthogonal polarization axes substantially aligned with an x and y axis of the crystal respectively. In operation light polarized at a selected angle of orientation to the x and y axes of the crystal is applied to one end of the wave guide and polarized light leaving the wave guide and polarized along two substantially orthogonal axes one of which is at about the same orientation to the x and y axes as the polarized light entering the wave guide is detected to determine the electric field to which the sensor has been subjected. Preferably the sensor will include polarization maintaining optical fibers appropriately oriented to the wave guide for delivering and receiving polarized light to and from the wave guide.

Abstract: L'invention a pour objet une installation permettant d'isoler un élément à palier magnétique contre les vibrations, par rapport à son stator, c'est-à-dire par rapport à son environnement, et inversement. Il peut s'agir en particulier d'un rotor (3) qui produit des vibrations parasites du fait de sa rotation. L'installation proposée permet d'assurer que la position de l'élément à palier magnétique suive les mouvements lents du stator, mais que les perturbations correspondant à des fréquences plus élevées ne soient pas transmises. Des opérations rapides appropriées de régulation de la position sont néanmoins possibles simultanément. L'élément essentiel de l'invention est un intégrateur double (15) qui produit un signal artificiel de capteur de position, largement exempt de perturbations, pour une régulation de la position avec de faibles vibrations, signal qui est ajouté peu à peu au véritable signal de capteur de position. L'invention peut être appliquée en particulier dans un volant pour la stabilisation des satellites, où elle permet un réglage de la position relative en même temps qu'une isolation par rapport aux vibrations.

Abstract: Un appareil amélioré de teinture par tuyères permet de teindre des tissus (11) légers ou relativement lourds dans un même appareil avec une plus grande efficacité et une qualité améliorée des produits. L'appareil comprend un mécanisme unique (7) de pliage monté sur l'extrémité de sortie d'un tuyau de transport (11) de manière à tourner autour du tuyau de transport (11), de sorte qu'une tuyère de sortie (15) orientée vers le bas définie par le mécanisme de pliage (7) effectue un mouvement alternatif le long d'un trajet de déplacement généralement linéaire, transversal au tuyau de transport (11), et de sorte que le tissu (1) qui traverse le tuyau de transport (11) soit déposé dans une chambre (10) de traitement liquide en plis surjacents relativement droits, afin de maximiser la capacité de l'appareil de teinture et d'améliorer la stabilité du tissu traité dans l'appareil. En outre, selon un aspect supplémentaire de l'invention, on peut obtenir une capacité plus élevée en utilisant un tuyau de transport (11) avec une pluralité de systèmes vaporisateurs (3, 4) du bain de teinture, ayant de préférence un profil en V, de sorte qu'une première zone de transport soit de préférence légèrement inclinée vers le bas et qu'une deuxième zone de transport qui contient la tuyère de pliage soit généralement inclinée vers le haut. L'invention concerne également un procédé apparenté de teinture de matières textiles.

Abstract: A process for removing organic liquid contaminants from an aqueous solution in which the contaminants are entrained comprises passing the solution through a contacting zone containing a fixed bed of a particulate thermoplastic elastomeric block copolymer selected from the group consisting of monovinyl aromatic-conjugated diene block copolymers, monovinyl aromatic-monoolefin block copolymers, and hydrogenated derivatives of such block copolymers; and recovering a substantially oil-free aqueous stream from the contacting zone. A method for removing hydrocarbon contaminants from soil comprises contacting hydrocarbon-contaminated soil with the above block copolymer and forming a homogeneous mixture of the block copolymer and the hydrocarbon-contaminated soil, contacting the homogeneous mixture with water, recovering block copolymer-encapsulated hydrocarbon contaminant from the homogeneous mixture, and recovering contaminant-free soil from the remaining mixture. A method for recovering an organic liquid film from a liquid body or solid surface comprises uniformly distributing the above block copolymer over the organic liquid film to encapsulate the liquid film in the block copolymer, and recovering organic liquid-encapsulated block copolymer from the solid surface.
