Abstract: « Procédé de mesure de vitesse ou déplacement ou position d'un moteur électrique, notamment dans un actionneur de freinage automobile »  L'invention se rapporte à un procédé(E1) de mesure de vitesse et/ou position d'une partie mobile(R1) au sein d'un moteur électrique(M1), notamment rotatif. Une unité électronique de commande(ECU) réalise les étapes suivantes :  activation(E10) dudit moteur, et application d'une tension d'alimentation aux bornes d'alimentation(M19) moteur, mesure(E12) d'un signal de variation d'intensité et/ou de tension aux bornes d'alimentation,analyse(E13) dudit signal de variation pour en détecter un ou plusieurs évènements(p1-p14, i1-i14) représentant un déplacement de ladite partie mobile dudit moteur.  On obtient ainsi une mesure directe du déplacement ou de la vitesse du moteur, par un traitement électronique, sans nécessiter de capteur spécifique dans le moteur ou l'actionneur.  L'invention se rapporte aussi à une unité de commande, ou un moteur ou actionneur, ou un frein ou un véhicule, mettant en œuvre un tel procédé.  Figure pour l’abrégé : Fig.1

Abstract: A method for the control of the proportion of two gases which are delivered to a mixed gas line for use for example in a respiratory breathing apparatus in which the gases are delivered to a mixed gas line from a pressure control vessel, comprises continuously monitoring the pressure in the control vessel and when the pressure therein is at an initial predetermined pressure admitting a first gas into the pressure control vessel until the pressure therein increases to a predetermined higher pressure and then stopping the admission of the first gas and initiating the admitting of a second gas into the pressure control vessel, continuing to admit the second gas until a predetermined additional higher pressure is achieved in the pressure control vessel, discontinuing the admission of the second gas when the predetermined additional higher pressure is reached and initiating the withdrawal of the mixed gas through the mixed gas line, continuing to withdraw the mixed gas through the mixed gas line until an initial pressure is again reached in the pressure control vessel at which time the complete process is repeated again. The apparatus includes a first control valve in a first gas supply line to the pressure vessel and a second control valve in a second gas supply line to the pressure control vessel. A third control valve is arranged in a mixed gas delivery line which connects the pressure vessel. All of the three valves are connected by a control device which is responsive to the pressure in the pressure vessel and the individual control valves are set for opening and closing at different control pressures so that the inflow of the first and second gases and the delivery of the mixed gases will be continuously controlled thereby.

Abstract: A succession of superposed digitized sections of an object are produced from a three-dimensional representation of the object. A powder or a mixture of powders is spread in the form of a fine layer and heated to a temperature close to solid phase sintering temperature of the powder or the mixture of powders. The layer is brought to the sintering temperature by scanning with a laser beam the layer such that a selected part of the powder, corresponding to one of the digitized sections of the object to be produced, is sintered in solid phase by the additional energy supplied by the laser. Additional layers of the powder or the mixture of powders are spread, heated and scanned with the laser beam until all the digitized superposed sections of the object to be produced are obtained.
