Patent EP-0485305-A1 (EP)
Inventor: FRIGIERE RENE
IPC: F23Q2/28
Filed: 1991-10-09
Abstract: This device is of the type comprising an electricity generator comprising a fixed or essentially fixed part (2) and a movable part (3) which is normally kept at a distance from the fixed or essentially fixed part (2) by a return spring, and the actuation of which has the effect of causing an ignition spark between two electrodes, the first (7) of which, fixed or essentially fixed and constituted by the burner/valve of the apparatus, is connected to the terminal (9) of the fixed or essentially fixed part (2) of the generator and the second (8) of which is fixed and has a rear extension (8a) which is elastically deformable and situated on the trajectory of the terminal (11) of the movable part (3) of the generator in such a manner that this terminal (11) comes into contact with it at the moment of the release of the electrical energy necessary for the production of the ignition spark, that is to say at the end of travel in the direction of ignition of the movable element (3) of the generator. 
<??>The second electrode (8) is made over its entire length from a metal wire which is elastically deformable and a good conductor of electricity, such as a spring steel.

Abstract: L'invention concerne un système de régulation des détonations d'un moteur à combustion interne à allumage par étincelle pourvu d'une commande de courte durée à l'aide de laquelle, en cas de détonations, la valeur d'un point d'allumage réel basé sur une entrée sous forme de diagramme caractéristique est remise à zéro par une course de commande dans le sens d'un retardement d'allumage. En l'absence de détonations, le point d'allumage réel est déplacé par une course de commande dans le sens d'un avancement de l'allumage pour regagner l'entrée du diagramme caractéristique. Selon l'invention, une adaptation de longue durée est réalisée grâce au fait que la sortie du diagramme caractéristique (1), en cas de détonations (K), est remise à zéro ou modifiée par une valeur d'adaptation (LZ) en s'écartant de la limite de détonation de sorte que la commande de courte durée se base sur une nouvelle sortie du point d'allumage ou sur une nouvelle valeur. Les valeurs d'adaptation (LZ) sont acquises en fonction des cas de détonations survenant pendant un intervalle de contrôle. Des variables appropriées pour l'acquisition des valeurs d'adaptation sont les valeurs moyennes des courses de commande dans l'intervalle de contrôle concerné.

Le jeton a un corps ayant sensiblment la forme d'un disque plat à surfaces opposées, avec des marques de code (44) imprimées ou frappées directement sur l'une des faces du jeton ou sur les deux. Les marques d'identification (44) comprennent des variations de surface alignées au moins partiellement à un certain angle par rapport au plan de la surface du jeton, ces marques étant décelables sous forme de variations réflectrices ou non-réflectrices, par exemple au moyen d'un détecteur optique ou d'une paire de détecteur-émetteur optique. Les marques d'identification peuvent être des anneaux ou des variations transversales étendues dans une direction qui va du centre jusqu'au rebord du jeton, lequel jeton est de préférence circulaire. Le code d'un jeton particulier est défini tout au moins par la présence d'une marque ou d'un dessin d'identification à un endroit déterminé, l'espacement des marques d'identification, et la correspondance ou la non-correspondance de marques sur les côtés opposés ou à des endroits différents du jeton. Le code peut être détecté lorsque le jeton passe à côté d'un détecteur, la rotation du jeton n'étant pas significative.

Abstract: A method of forming a multiport optical fiber coupler in which a bundle of seven optical fibers are located in close-packed hexagonal array within a capillary tube and twisted. An optical source is coupled to an outer fiber. A fused, tapered coupler is formed, the tapering being stopped when the minimum of optical power outputs is first maximized. This provides a 6x7 optical fiber coupler. Also disclosed is a 7x7 optical fiber coupler formed by fusing the coupler during formation sufficiently to provide that the maximum insertion loss through the device between any input and output is minimized.

Abstract: An apparatus and method for determining the cardiac output is described. In this case, a prescribed quantity of indicator dye is injected into the blood circulation, and measurement of the dye concentration is carried out over a sufficient period. The calculation of the cardiac output is performed using the prescribed quantity of injected indicator dye (m0) and the dye concentration time curve (cind(t)), on the basis of the principle of the conservation of mass in accordance with the formula given by Stewart Hamilton. <IMAGE>   The dye concentration time curve is measured non-invasively at suitable body locations by light-transition or light-reflection measurement of irradiated light. In this case, the internal reference variable is provided by a further dye, serving as reference dye, with known characteristics. Haemoglobin is preferably used as reference dye. <IMAGE>

Abstract: In a process for the preparation of hydrochloric acid, which is free of the other halogens, fluorine, bromine and/or iodine, or hydrogen compounds and salts thereof, from a crude dilute hydrochloric acid, in particular a crude hydrochloric acid obtained in waste gas scrubbing, which contains at least fluorine as another halide, a fluoride precipitant in the form of a soluble chloride salt is added to the crude dilute hydrochloric acid for separating off hydrogen fluoride and fluorides, and the resulting precipitate is separated off during the precipitation reaction and before the subsequent distillation and/or rectification. The prior separation, provided if necessary, of hydrogen bromide and/or hydrogen iodide and salts thereof from the crude dilute hydrochloric acid is carried out by adding chlorine in such a quantity that the elemental halogens bromine and/or iodine are set free, and these are separated off and obtained as a reusable product. The purified hydrochloric acid can be taken without difficulties to any desired industrial further processing. <IMAGE>

Abstract: The present invention purports to provide a tape recording/reproducing apparatus capable of causing a plurality of tapes having different width respectively to travel smoothly and its cassette. The cassette positioning spring 1 gives an appropriate pressing force even in the case that the cassettes have different thicknesses, and the cassette are respectively fixed at predetermined positions so that the lower edges of the magnetic tape 3a, 3b are positioned at the same height. The flange 9 of the guide post 12 is shifted in an up-and-down direction in response to a magnetic tape width signal detected through the cassette detecting switch 13 or the beginning edge detector 14a, or the ending edge detector 14b, so that even narrow magnetic tape 3a can travel at the predetermined height. Furthermore, by changing the inclined angle and/or the inclined direction of the movable post 10, a downward torsion force is applied to the narrow magnetic tape 3a. In this fashion, magnetic heads to be used are selected in accordance with the magnetic tape width detected by the cassette detecting switch 13 or the beginning edge and the ending edge detectors 14a, 14b.

Abstract: The invention relates to a method for forming dental impressions using an impression tray (1, 2) having a groove-shaped mould case (15). In an individualisation process step preceding preparation of the impression, a highly viscous curable impression material (11) is applied around the edges (4, 3) of the impression tray, and the impression tray is then pressed with its edges against the mobile mucous membrane. After curing of the highly viscous impression material the impression tray is removed from the jaw together with the impression material. In a subsequent process step, the mould case of the impression tray, which has previously been fully individualised, is filled with a curable impression material of low viscosity, and the impression tray is then pressed onto the jaw with its edges resting against the mobile mucous membranes. The patient is instructed to mobilise the mobile mucous membranes. After curing of the impression material of low viscosity whose maximum final hardness is 30 Shore A the fully individualised impression tray is removed from the jaw together with the impression material. The grooved bottom of the mould case of the impression tray which has previously been fully individualised can be lined with a curable, kneadable material. …<IMAGE>…
