Patent EP-0085258-A1 (EP)
Inventor: OVERINGTON MARTIN THOMAS
IPC: F02B19/12
Filed: 1982-12-24
Abstract: An internal combustion engine of the spark-ignited piston type has a piston crown of "pent-roof' shape and a cylinder head combustion chamber of corresponding shape. Formed on one inclined face [22] of the combustion chamber [20] is a recess [30] of generally ovate profile, having a plane roof [32] parallel to the face [22] and having a side wall [31] perpendicular thereto. The exhaust valve port [29] opens through one end of the roof of the recess [30] and the spark plug [37] protrudes through the other end. During the compression stroke as the piston [12] approaches top-dead-centre, gas is displaced by the "squish" effect from between the approaching inclined faces [16] and [21] of the piston crown and combustion chamber roof on one side of the apex [18,] [23] and travels across the combustion chamber and into the recess [30] in the other side of the roof thus producing gas movement and turbulence in the recess [30] where ignition takes place.

Abstract: The device for facilitating the extracorporeal circulation of some of the blood of a living being is characterised in that it comprises means permitting compression of part of the circumference of a limb of the said living being, over a certain length of the said limb, in such a way as to concentrate the peripheral venous blood flow of the limb in at least one vein (12) situated in the part of the circumference of the limb which is not compressed by the device, at least the sampling of the blood being carried out on the non-compressed vein. The method involves compressing a part of the circumference of the arm of a patient in such a way as to concentrate the peripheral venous blood flow in a non-compressed vein from which the blood sample is taken and in an advantageous manner into which the blood is reinjected after it has circulated outside the patient. Application of the device and the method in particular for plasmapheresis. <IMAGE>

Abstract: Le sommier à lattes avec rouets à corde, destiné à être utilisé en tant que composant de support pour bases de siège ou de lit, se compose d'un cadre (1) sur lequel sont montés des rouets à corde (3) de chaque côté du cadre (1). Les lattes élastiques (2) sont maintenues par une corde (4) et par des rouets (3) montés sur les lattes élastiques (2), et par les rouets (3) montés sur le cadre. Le fonctionnement du sommier à lattes avec des rouets à corde se caractérise en ce qu'il modifie sa forme pour soutenir l'utilisateur en fonction des mensurations de l'utilisateur, et que le degré de déformation peut être déterminé par l'utilisateur pour obtenir une adaptation optimale. Le sommier à lattes avec rouets à corde peut être construit de manière à modifier sa forme également dans la direction de la largeur selon le même principe déterminant la déformation longitudinale. Grâce à cette capacité d'épouser la forme du corps de l'utilisateur, la partie de coussinet ou matelas peut être également plus mince que dans des bases conventionnelles de siège et de lit, ce qui permet d'en assurer aisément la ventilation.

Abstract: A first embodiment of an assembly fixture (2) for locating an electrical connector (42,102) and a cable (54) with respect to each other for assembly includes adjustable connector locating guides (18, 20) mounted on a base plate (4) and adjustable cable guides (68, 70) mounted on a spring-loaded tiltable cable platform (6) spaced above the base plate (4). As the cable (54) is forced downwardly into the connector (42, 102), the cable platform (6) tilts to accommodate the relative motion of the cable (54) with respect to the fixture (2). After the cable (54) is assembled to the connector (42, 102), the cable platform (6) returns to its normal horizontal position, partially removing the connector (42, 102) from the connector locating guides (18, 20). A second embodiment of an assembly fixture (104) includes a connector support (114) which has spaced lands (120) which support the entire area of the connector (124,132) to prevent breakage of the connector (124, 132) during assembly.

Abstract: @ in a communication system which includes a plurality of stations (23,24) interconnected for communications by a first bus (21), a second station (22) includes a device, such as a processor (25), and a resource, such as a memory (32) or a peripheral unit, interconnected for communication by a second bus (36). An interface mechanism (34) connecting the first bus with the second bus allows the device to access the first bus over the second bus, and allows a first station to access the resource via the first and second buses. Deadlock detection circuitry (47) detects cotemporaneous attempts by the device to access the first bus and attempts by the first station to access the resource. Deadlock resolution circuitry (26) responds to deadlock detection by disconnecting the device from the second bus to allowthe first station to access the resource, and by reconnecting the device to the second bus when the first station ceases to access the resource. If the device is operating under program control, the deadlock detection and resolution are transparent to the program (Fig 1).

Abstract: Un indentation formée dans un échantillon est balayée et son image est saisie en utilisant un dispositif de mise en image par balayage unidimensionnel. Lorsque l'indentation est quadrangulairement pyramidale un signal représentant la longueur d'une ligne diagonale de l'indentation est produit; lorsque l'indentation est sphérique un signal représentant le diamètre de l'indentation est produit, calculé à partir du signal de sortie du dispositif de prise d'image. Le balayage au moyen du dispositif de prise d'image à balayage unidimensionnel n'est pas effectué sur toute la largeur de l'indentation mais au travers d'une première région avec une largeur réduite qui comprend une première ligne diagonale de l'indentation lorsque celle-ci est quandrangulairement pyramidale et qui comprend une ligne représentant le diamètre de l'indentation dans une première direction lorsque l'indentation est sphérique. Lorsque l'indentation est quandrangulairement rectangulaire, le balayage s'effectue en outre au travers d'une deuxième région de largeur réduite qui comprend une deuxième ligne diagonale de l'indentation, ou bien au travers d'une troisième et d'une quatrième régions qui comprennent deux sommets de la deuxième ligne diagonale de l'indentation et qui sont parallèles à la première région, respectivement.

Abstract: A process wherein, to produce the preform, pulverulent glass starting material is deposited on a substrate by a method in which it is electrostatically charged before the deposition and accelerated toward the substrate surface to be coated by means of a counterelectrode. If the substrate is a rod-shaped substrate (1), which may be made from conductive material, this substrate can itself be used as the counterelectrode. If the substrate is a glass tube whose internal surface is to be coated by deposition of the pulverulent glass starting material, the counterelectrode used is an annular electrode (16) surrounding the glass tube (10). The charging of the particles of the pulverulent glass starting material, which is sprayed onto the surface to be coated, is effected on emergence from a spraying device (2) whose spraying nozzle (3) is connected to a high voltage. After deposition of one or more layers, the material applied is sintered and at the same time electrically discharged. <IMAGE>
