Abstract: L'invention se rapporte à un coupleur servant à relier par couplage des composants électroniques haute vitesse pour l'échange bidirectionel de signaux entre eux et conçu en particulier pour l'acheminement de tels signaux en direction de diodes laser, excitées par deux signaux haute fréquence ou par des impulsions trés courtes, et en provenance de photodiodes haute vitesse. Le coupleur se compose d'un dispositif obtenu par l'assemblage d'au moins deux structures à lignes de transmission planes différentes, le conducteur central porteur de signaux (22, 31) étant partagé par toutes les structures ainsi assemblées, tandis que les plans horizontaux (26, 27, 29, 32, 33, 34, 36) maintiennent la position caractéristique de chacune des structures ainsi assemblées par rapport au conducteur. La variation d'impédance caractéristique, qui passe de l'impédance de ligne habituelle de 50 ohms à une impédance de diode de 5 ohms, est obtenue progressivement le long du dispositif par l'intermédiaire de l'effet cumulatif des variations d'impédance individuelles de chaque structure à ligne de transmission formant le coupleur, ces variations résultant du changement graduel des dimensions de la section transversale du coupleur dans le sens de la longueur.

Abstract: Un dispositif sert à connecter des lignes de courant de commande dans des installations de distribution électrique de basse tension. Le dispositif doit permettre de maintenir aisément le courant de commande dans un panneau de distribution à tiroirs enfichables jusqu'à une position de test du tiroir enfichable et d'interrompre le courant lorsque le tiroir est déplacé au-delà de cette position. Le dispositif comprend deux barres de contact avec des prises mâles et femelles. La première barre de contact est fixée au tiroir et l'autre est mobile sur un trajet limité, étant montée sur deux tiges de guidage dont les extrémités ont une section transversale élargie. Dans la position de test, des éléments élastiques assurent un encliquetage qui entraîne une mise en contact complète entre les deux barres de contact dans cette position, déjà lorsque l'on insère le tiroir. On peut ainsi câbler aisément et avec peu de frottement, dans un espace réduit, une pluralité de lignes de commande dans un panneau de distribution à tiroir enfichable, et atteindre une position de test en tirant le tiroir.

Abstract: L'invention se rapporte à une structure lourde, par exemple, un pont comprenant un élément sujet aux vibrations de basse fréquence lors de l'édification, c'est-à-dire lorsque la structure est instable; un autre élément faisant partie intégrante de la structure après édification sert de masse d'un absorbeur dynamique pour amortir ces vibrations. Dans l'exemple donné, un rail de lancement (46) utilisé dans l'édification d'un pont au-dessus d'une rivière est monté en porte-à-faux au-dessus de la rivière; ce rail de lancement comporte un pied support (50) qui se déploie à l'aide d'un vérin intégral pour venir en contact avec le sol et former une structure stable. Le pied support comprend une partie inférieure (54) qui est suspendue lors de l'édification à partir de la partie supérieure du pied par un ressort à gaz, le ressort à gaz et la masse de la partie inférieure constituant ensemble un absorbeur dynamique du rail de lancement dans l'édification d'un pont. Après l'édification, des charges structurelles sont transmises directement à la partie inférieure du pied par l'intermédiaire d'un tourillon. Le ressort à gaz comprend un réservoir d'air, dont le volume effectif correspond au moins approximativement au corps amorti.

Inventor: FREUND LUDWIG
IPC: G01P13/04

Abstract: The invention relates to a method and an arrangement for detecting a direction of movement, especially a direction of rotation, using two signals which are phase-shifted by 90 DEG  and are derived from two receivers (3, 4) arranged offset relative to one another in the direction of movement. It is the object of the invention to generate the signals that are phase-shifted by 90 DEG  without the accuracy of the phase shift depending substantially on the accuracy of the mechanical positioning of the receivers. According to the invention, the object is achieved when in order to determine the direction of movement two sinusoidal signals that are phase-shifted by 90 DEG  are formed from periodic output signals of the receivers by adding and subtracting the output signals. The sum signal and the difference signal are digitised in a known way and further processed in order to establish the direction of movement. The application of the invention enables a less precise manufacture and installation of the sensor. <IMAGE>

Abstract: The mould is designed for pressing ceramic wall and floor tiles (26) affording one or more re-entrant grooves (28) or recesses (31) in the reverse face, of which the undercut surfaces are suitably angled in relation to an axis normal to the fixing plane and of width as much as equal to the depth of the tile. The ridged reaction plate (10) of the bottom die (3) is capable of vertical motion and affords one or more upwardly projecting longitudinal inserts (21) with angled lateral surfaces by which the re-entrant profile is generated; the inserts are forced to descend during the forcing stroke in relation to the bottom die plate (10) through a distance equivalent to half the stroke or thereabouts, and thereafter, elevated marginally by springs (24) just enough to distance the tile from the top surface of the bottom die and enable its removal in a sideways direction. 
     The back of the single tile, ceramic or otherwise, obtained with the mould affords one or more grooves running either the full length of the body or less, of which the cross sectional profile exhibits parts undercut from the reverse face to significant and even bold depths, in relation to the thickness of the tile, and is of geometry such as to accommodate a close-fitting longitudinal anchor strip (38) of of a relative fixing device, having matching profile; the rear face of the strip has flexible lugs (37) that can be snapped firmly into and, if necessary, removed from corresponding slots (36) fashioned in a longitudinal support (35) of ridged profile secured beforehand to the subsurface.
