Patent EP-0277427-A1 (EP)
Inventor: HODGKINSON TERENCE GEOFFREY
IPC: G02F1/01
Filed: 1987-12-16
Abstract: The invention provides methods and devices for processing an optical signal. In one embodiment, an optical device (101) for scrambling an input optical signal comprises an optical switch (10) which switches the optical signal between two intermediate optical paths (13,14) under control of a scrambling signal from a control circuit (12). The polarisation of the signal in one of the intermediate optical paths (13) is rotated by a TE-TM converter (15). The polarisations of the two intermediate signals are thereby made mutually orthogonal. These mutually orthogonal signals are then recombined by a directional coupler (16) to provide a combined output optical signal with a scrambled polarisation alternating between othogonal states according to the frequency of the scrambling signal. 
     The invention may be applied to improve signal reception, for example, in coherent optical transmission systems.

Abstract: Une antenne à cornet hybride à large bande comprend un cornet (1) de section circulaire alimenté par un guide d'alimentation circulaire (3). Une tige diélectrique (7) est montée en porte-à-faux dans l'extrémité d'étranglement (4) du cornet (1) et présente une section conique pour permettre au guide (3) de s'y adapter. Ladite tige a une section avant conique dont la base est de même diamètre que le guide et dont le diamètre du sommet est égal à environ 2 mm immédiatement à l'extérieur de l'embouchure (11) du cornet (1). Les différentes dimensions de l'antenne - diamètre du cornet au niveau de l'étranglement et de l'ouverture, angle d'évasement, diamètre décroissant de la tige en raison de la conicité et longueur de la tige - sont toutes choisies afin d'obtenir un équilibre des effets opposés se produisant sur la largeur de faisceau et pour obtenir ainsi une largeur de faisceau fixe pratiquement indépendante de la fréquence sur une large bande. Une largeur de bande étendue, située dans ce cas entre 8 et 16 GHz, est ainsi obtenue avec une largeur de faisceau pratiquement constante sur la bande.

Abstract: For formed parts such as are used, for example, in vehicles, synthetic resins are normally used as binders for the fibre materials. In contrast, it is proposed to use gypsum binders or modified gypsum binders, which can be modified with small additions of plastics, for producing these formed parts, which accurately retain their shape even under the action of moisture. Further advantages are the non-flammability and the reduced gaseous emissions.

Abstract: Un récepteur de recherche de personne (10) est compatible avec des transmissions provenant d'émetteurs de recherche de personne analogiques ou numériques. Le récepteur de recherche possède une structure de commande qui lui permet d'être programmable dynamiquement pour changer sa fonctionnalité, y compris la programmation de fréquences de canaux que le récepteur de recherche va recevoir. La programmabilité des fréquences de canaux permet au récepteur de recherche de personne d'être utilisé pour effectuer des recherches de personne sur un plan national, régional, local, une zone éloignée, et pour envoyer des avis de recherche à un groupe dans une région locale ainsi que pour effectuer une commutation des fréquences de canaux qui sont utilisés intensivement pendant les périodes de pointe pour passer à des canaux moins utilisés. Le récepteur de recherche de personne transmet les chiffres d'un code d'identification du récepteur dans un ordre d'importance croissante ce qui réduit de manière considérable la consommation d'énergie de tous les récepteurs syntonisés sur une fréquence particulière pour déterminer si un avis de recherche doit être reçu, ce qui permet de prolonger la vie des piles du récepteur. Le récepteur affiche le lieu d'origine des messages de recherche, soit comme une origine locale soit d'autres origines. L'antenne (12) du récepteur est syntonisable en continu pour permettre la compensation des variations du gain de l'antenne dues aux facteurs de l'environnement qui peuvent dégrader sérieusement la force du signal.

Abstract: The invention relates to a drive unit for a mixing and/or kneading machine (1) having at least one tool (3a) revolving in a vessel (2) and also rotating about its axis. The tool (3a) is here mounted in a rotary body (4) eccentrically and approximately parallel to the axis of rotation thereof and is set in revolving motion by the rotation of the rotary body (4). The drive force acting on the rotating rotary body (4) is transmitted from a drive motor (7) via a reduction having a planetary gear (8) to the tool (3a) which also rotates about its own axis and which, for this purpose, is joined securely against rotation to a planet wheel (9) of the planetary gear (8), which rolls over its sun wheel (10) arranged coaxially to the axis of rotation of the rotary body (4). In order to vary, independently of the selected reduction between the sun wheel (10) and the planet wheel (9), the relation between the speed of revolution of the tool (3a) and its own speed of rotation, the sun wheel (10) is, according to the invention, rotatably mounted and has its own additional drive (15) for the actual rotation of the kneading tool(s) (3). As a result, these speed of rotation ratios can readily be adapted, for example, to the viscosity or consistency, variable during a mixing process, of a product to be treated. <IMAGE>

Abstract: An apparatus and method for processing first and second signals, the second signal representing information which is delayed in time with respect to corresponding information represented by the first signal and there being included in the information represented by each signal information which represents a common effect, occurring at the same time, in each of the two signals. The apparatus includes correlating means which generate first data suitable for producing a positive time correlation curve from the two signals and second data suitable for producing the equivalent of a negative time correlation curve from the two signals or an autocorrelation curve from either one of the two signals. The information representing the common effect results in data common to both first and second data. One of the first and second data is therefore subtracted from the other, thereby removing or substantially reducing the information representing the common effect. The apparatus and method are particularly suited for measuring the speed of travel of a cable in a cable making machine, where lateral movements of the cable away from its desired path produce a common effect on sensors spaced lengthwise of the direction of travel.

Abstract: A mechanism for automatically orientating cup bodies (U) includes a cup body rotating means (3, 2a-e), means (5, 6) for measuring a peripheral configuration of the side wall of a cup body (U), and a central control means (8) for comparing the peripheral configuration of the side wall thereof with the peripheral configuration of the side wall of a sample cup body. The central control means (8) determines whether the two peripheral configurations coincide with each other, and determines the angle by which the cup body (U) is to be rotated to orientate it in the right position for the connection with a handle thereto, if the two peripheral configurations do not coincide with each other. Then, the central control means (8) signals the cup body rotating means (3, 2a-e) to rotate the cup body (U) through the required angle to orientate the cup body (U) in the right position.
