Patent EP-0316691-B1 (EP)
Title: Device for checking the closed state of a closing element
IPC: E05F15/655
Filed: 1988-11-05
Granted: 1993-03-10
Abstract: The invention relates to a system for monitoring the closing of a door or other such barrier, such as a sliding door of a vehicle. This system has a circuit outside of the door which serves to emit a signal indicating the open or closed state of the door. In the production of this signal, the need for any electromechanical limit switches or indicating devices mounted on the door and coupled galvanically with the circuit is avoided by providing, in accordance with the invention, a circuit that is mounted on the door. Both circuits have at least one inductive element. The inductive elements are coupled only inductively with one another, but are not in physical contact with one another, so that the production of the signal indicating the open or closed state of the door can be performed contactlessly.

Filed: 1988-10-12
Granted: 1992-01-02
Abstract: A gasolene fuel injector in which the valve member (24) is in the form of a plate which is attracted towards a pair of pole faces when a winding (17) is energised. The extent of movement of the valve member is limited by a non-magnetic spacer member (27) which is of annular form. In order to reduce the possibility of the valve member sticking to the spacer member the contact area between the valve member (24) and spacer member (27) is minimised by the provision of inwardly extending tongues (28), the tongues being engaged by the valve member.

Abstract: Un rail de roulement (17) est monté sur un support (2) et passe entre deux rails de support (15, 16) parallèles fixés l'un au dessus de l'autre à un autre support (1). Les rails de support et le rail de roulement s'étendent sur toute la longueur du support concerné. Chaque rail de support (15, 16) comporte sur ses faces supérieure et inférieure une rainure longitudinale (18, 19, 20, 21), qui forme une voie de roulement pour les corps de roulement (22) guidés par une bande sans fin pourvue de cages. Sur le rail de roulement (17) sont prévus des contre-rails (23, 24). Les bandes à cages présentent des deux côtés des nervures (32) parallèles à la voie de roulement. Ces nervures (32) servent à guider les bandes à cages latéralement dans les rainures longitudinales (18, 19, 20, 21). Cet appui longitudinal rend possible le guidage précis de longs supports longitudinaux, prend peu de place en hauteur et est facile et bon marché à fabriquer et peut convenir pour chaque longueur de support.

Abstract: Machine-outil possédant un plateau de montage de la pièce à usiner. Selon les techniques conventionnelles, une pièce à usiner est découpée avec une première machine-outil et une rainure est formée ensuite dans une surface plate à une extrémité de l'outil par une autre machine-outil. Ce procédé exige que la pièce à usiner soit démontée d'une machine-outil et fixée dans une autre. La présente invention permet d'éliminer ces inconvénients. Le châssis (1) d'une machine-outil est pourvu d'un plateau de montage de la pièce à usiner (2). Ce plateau (2) est pourvu d'un plateau rotatif (3). Afin d'usiner la pièce, on place cette dernière sur le plateau rotatif (3). Afin de soumettre la pièce à un processus autre que l'usinage, on la place sur le plateau (2). Dans ce dernier cas, la pièce peut également être placée sur le plateau (2) et sur le plateau rotatif (3) de manière à s'étendre sur les deux plateaux.

Abstract: Instrument composé d'un cylindre en alliage à mémoire de forme permettant de maintenir constant le diamètre interne du passage d'un organe tubulaire, cet instrument étant traité de manière à augmenter le contraste de l'image radiographique en soumettant au moins une partie du cylindre à placage ou à dépôt sous vide d'un métal présentant une densité supérieure à celle de l'alliage à mémoire de forme. Par conséquent, cet instrument peut être introduit à demeure à l'endroit désiré de l'organe tubulaire. Cette invention se rapporte également à un dispositif de maintien du diamètre interne d'un passage, pouvant rester dans le passage ou en être extrait, ayant essentiellement une forme cylindrique, combiné avec un alliage à mémoire de forme bidirectionnelle dont la dimension radiale varie en fonction des changements de température. Ce dispositif comprend un cathéter pouvant adapter l'instrument de maintien de diamètre interne sur la surface périphérique externe d'un élément s'adaptant à l'instrument à proximité de la pointe, et une gaine de cathéter dont les deux extrémités sont ouvertes, pouvant loger le cathéter sur lequel est monté l'instrument contracté dans le passage, et dont le diamètre interne est égal ou inférieur au diamètre externe de l'instrument déployé pour maintenir le diamètre interne. Ledit instrument peut être maintenu de manière fiable dans la gaine de cathéter pendant qu'on le monte sur le cathéter. Il n'est ainsi pas nécessaire de faire circuler de grandes quantités d'eau de refroidissement afin de maintenir un diamètre réduit pendant l'enroulement de l'instrument autour du cathéter sans former d'interstices, ce qui permet également de réduire l'inconfort du patient. Grâce à l'utilisation de la gaine de cathéter, l'instrument de maintien du diamètre interne n'est pas exposé à l'organe tubulaire, ne se coince pas pendant l'introduction et ne subit pas de déformations.

Abstract: A rolling mill wherein the frame or frames for pairs of superimposed rolling tools can be lifted off the base by a crane. Each rolling tool carries a first clutch element receiving torque from a separable discrete second clutch element on a support which is adjacent a properly installed frame. The support is mounted on a reciprocable carriage, together with or independently of a drive for the second clutch elements, and can be moved in the axial direction of the tools toward and away from the adjacent frame. The upper second clutch element of the pair of second clutch elements on the support is movable up and down by a fluid-operated motor toward and away from a position of alignment with the corresponding first clutch element. The second clutch elements have pins which enter registering sockets in the adjacent first clutch elements, or vice versa, and the second clutch elements are axially movably mounted in their bearings on the support and are biased toward the respective first clutch elements. The second clutch elements are disengaged from the respective first clutch elements by moving the support away from the adjacent frame. A sensor cooperates with a stop to ensure that each movable second clutch element moves to a position of accurate alignment with the respective first clutch element, and the carriage can be moved toward the frame only when the alignment of the movable second clutch element with the respective first element is completed.

Abstract: A method of generating pure and decaying sinusoidal waveforms is readily implemented on arithmetic processors found in telecommunications circuits. The method is based on finite-difference equations and provides a sequence of signals having a high degree of spectral accuracy compared with presently-used methods. The sequence of signals can be generated in real-time without templates (ROM-stored patterns) because the method requires only two multiplications (16,18) and one addition (12) for each signal value generated in the sequence. The method finds application in dual-tone, multi-frequency (DTMF) telephone dialing systems.
