Heat sink for an electric circuit board

Abstract: A heat sink (4) intended for mounting along the edge (3) on an electrical circuit board (1) in order to cool heat-generating components (2) on the circuit board. The heat sink (4) is designed with on the one hand a longitudinal slot (5) for mounting on the circuit board (1) and on the other hand a mounting flange (6) located in substantially the same plane as the slot (5). The design of this mounting flange (6) means that a circuit board (1) provided with a heat sink (4) can be mounted in guide tracks or equivalent in the same manner as a circuit board (1) without heat sink (4). The design of the heat sink (4) also means that the same heat sink (4) can be used for different circuit boards (1) and different components (2).

Process, plant and emulsifying substance for disposing of pollutant-containing materials

Abstract: The invention relates to a disposal method for solid and liquid materials contaminated by at least predominantly lipophilic pollutants, in particular hydrocarbons and the like, especially for oil-contaminated soils and waters, and to plants and emulsifying substances suitable for carrying out the process. The contaminated materials are intimately mixed with at least one emulsifying substance and, if required, with water, to give a microdisperse emulsification of the pollutants. The emulsion is then separated off from the material, with addition of water, and preferably biologically degraded.

Method, system and emulsifier substance for treatment of materials containing harmful substances

Abstract: The invention concerns a method for treatment of solid and fluid materials contaminated by at least predominantly lipophilic harmful substances, in particular hydrocarbons and the like, especially for oil-infested grounds and waters, as well as suitable systems and emulsifier substances for carrying out the method. The contaminated materials, for microdispersed emulsifying of the harmful substances, is intimately mixed with at least one emulsifying substance as well as possibly with water. Subsequently, the emulsion is separated from the material while adding water, and preferentially biologically decomposed.

Device for the selective detection of objects

Abstract: Un dispositif pour la detection selective d'objets, tels des aeronefs, missiles, helicopteres et similaire, au moyen de rayons emanant des objets, de preference des rayons infrarouges, comporte au moins une unite de detection (1). A device for the selective detection of objects, such as aircraft, missiles, helicopters and the like, by means of rays from the objects, preferably IR rays, comprising at least one detection unit (1). Ce dispositif comporte au moins deux entrees optiques situees a distance l'une de l'autre sur une ligne de mire allant du dispositif a l'objet. This device comprises at least two optical entrances arranged at a distance from each other on a sight line from the device to the object. L'unite de detection (1) comprend au moins un moyen de focalisation (15) destine a focaliser les rayons sur un plan focal. The sensor unit (1) comprises at least one focusing means (15) for focusing the radiation on a focal plane. L'unite de detection est equipee d'au moins un element detecteur (16) sensible au rayonnement et apte a emettre des signaux correspondant au rayonnement. The detection unit is equipped with at least one detector element (16) sensitive to radiation and able to emit signals corresponding to the radiation. Le dispositif est apte a balayer de maniere variable un angle de visee en azimut et/ou en elevation. The device is adapted to scan variably an angle of view in azimuth and / or elevation. Le dispositif comporte egalement une unite d'evaluation (2) apte a recevoir lesdits signaux. The device also comprises an evaluation unit (2) capable of receiving said signals. L'invention est caracterisee notamment en ce que l'unite d'evaluation (2) est apte a selectionner des objets qui lui semblent etre de taille similaire par rapport a l'angle mesure depuis la position du dispositif, d'une part des objets de grande dimension se trouvant a une distance eloignee, tels des aeronefs, etc., et d'autre part des objets de faible dimension situes a une distance rapprochee, tels des oiseaux, en supprimant des signaux dont l'amplitude en fonction de l'angle d'azimut ou d'elevation balaye est relativement grande compare a des signaux presentant une intensite relativement faible. The invention is particularly characterized in that the evaluation unit (2) is adapted to select objects that seem to be of similar size with respect to the angle measured from the position of the device, first objects Big dimension is at a remote distance, such as aircraft etc., and on the other hand small dimensions of objects at a close distance, such as birds, by suppressing signals whose amplitude as a function of the azimuth or elevation angle swept is relatively large compared to signals having a relatively low intensity.

Cooling body for an electric circuit card and method to arrange such a cooling body in an electronic unit

Abstract: A heat sink (4) intended for mounting along the edge (3) on an electrical circuit board (1) in order to cool heat-generating components (2) on the circuit board. The heat sink (4) is designed with on the one hand a longitudinal slot (5) for mounting on the circuit board (1) and on the other hand a mounting flange (6) located in substantially the same plane as the slot (5). The design of this mounting flange (6) means that a circuit board (1) provided with a heat sink (4) can be mounted in guide tracks or equivalent in the same manner as a circuit board (1) without heat sink (4). The design of the heat sink (4) also means that the same heat sink (4) can be used for different circuit boards (1) and different components (2).

Arrangement for a seat

Abstract: L'agencement pour siege decrit est destine a etre installe dans le dossier d'un siege afin de masser le dos d'une personne assise dans le siege. The described arrangement for seat is intended to be installed in the back of a seat to massage the back of a person sitting in the seat. Cet agencement comprend deux organes pulsatoires identiques (5) destines a etre disposes dans des evidements menages dans le materiau de rembourrage du siege. This arrangement comprises two identical pulsating elements (5) to be disposed in recesses in the seat cushioning material. Chaque organe pulsatoire (5) comprend un moteur d'entrainement electrique (11) servant a entrainer un certain nombre d'elements de massage (29-32). Each pulse element (5) comprises an electric drive motor (11) for driving a number of massaging elements (29-32). Les moteurs d'entrainement (11) sont connectes a un systeme de commande electrique commun qui, pendant un cycle de travail limite dans le temps, fournit par intermittence une tension aux moteurs d'entrainement (11). The drive motors (11) are connected to a common electric control system which, for a limited duty cycle over time, provides a voltage intermittently to the drive motors (11).

A vision system with a picture capture device and a picture reproduction device.

Abstract: A video system comprises a device for capturing images (1) with at least two cameras (5, 8) each having an optical means (6, 9) and an electro-optic detection means (7, 10), and that having an image reproduction device at least one display area (15) for simultaneously displaying images from the cameras. The video system is characterized in particular in that a first camera (5) for recording a first image with a first angle of relatively large aim, an object field (4) while a second camera (8 ) is for recording a second image with a second angle of lower sight (11) contained within said first viewing angle, said object field. The image reproducing device (2) is intended to reproduce the first picture, the second picture replacing to an optional degree that part of the premierre image that corresponds to the second viewing angle. The first and second viewing angles have the same direction relative to the object field as in the pictures reproduced by the image reprouction device (2), the enlargement of the relationship object field / expansion of image reproduction is identical to the first and second images.

Connected to the housing section (7) is an inlet channel (26) for the engine's surplus fuel and an evacuation channel (17) which is connected to the fuel chamber (2).

Influence Of Domeheating On Offset And Gain Correction In An IR-CCD Missile Seeker

Abstract: Dome heating effects in an IR-CCD missile seeker have been investigated. The background radiation as a function of time after launch and the charge generated in the IR-CCD storage well has been calculated for two dome materials. Demands on the signal processing in order to maintain an optimized seeker sensitivity and dynamic range during the flight envelope are also discussed.
