Patent EP-0479958-A1 (EP)
Inventor: REITER FERDINAND
IPC: F02M51/08
Filed: 1991-03-22
Abstract: Dans les soupapes d'injection de carburant à commande électromagnétique de type connu, le parcours d'ouverture du pointeau de la soupape est limité par une tige de butée qui, en position d'ouverture de la soupape, repose contre la face extérieure du pointeau opposé au siège de soupape. Des soupapes d'injection de carburant de ce type ont une longueur importante et ont un mauvais comportement dynamique dû à la masse élevée du pointeau. La nouvelle soupape d'injection de carburant présente, dans un trou borgne (6) du pôle intérieur étagé (1), une tige de butée (38) émergeant dans l'alésage traversant (34) de l'induit (30) en forme de tube. En position d'ouverture de la soupape, la pièce de fermeture sphérique (31) de cette soupape repose contre la tige de butée (38). L'induit (30) est relié directement à la pièce de fermeture (31), ce qui permet d'obtenir un élément de soupape à très faible déplacement. La soupape d'injection de carburant selon l'invention non seulement présente un bon comportement dynamique, mais est également courte et compacte. La soupape d'injection de carburant convient en particulier pour des installations d'injection de carburant de moteurs à combustion interne à allumage commandé d'un mélange comprimé.

Abstract: PCT No. PCT/GB91/00634 Sec. 371 Date Dec. 16, 1992 Sec. 102(e) Date Dec. 16, 1992 PCT Filed Apr. 22, 1991 PCT Pub. No. WO91/16531 PCT Pub. Date Oct. 31, 1991.A fuel supply control for an internal combustion engine designed to run on gaseous fuel (LPG or CNG) utilizes a feedback loop from a lambda sensor in the exhaust gases to a moving coil (82) mounted on a diaphragm (34) of a diaphragm-actuated valve (24) controlling the flow of gaseous fuel to the engine. The coil (82) is similar to the speaker coil of an audio speaker, and moves concentrically of a fixed permanent ring magnet (86) to impart a variable bias on the diaphragm(34) in accordance with the oxygen content of the exhaust gas stream as sensed by the lambda sensor, to control the fuel or air-and-fuel supply to the engine in accordance with desired engine operation parameters. The control has a sufficiently rapid and positive response that it can maintain the free oxygen content in the exhaust gases at substantially 2% for continuous operation of a catalytic exhaust purifier at or nearly at optimum efficiency.

Title: Revetements superficiels durcissables a la temperature ambiante, et leur procede de production et d'application
Inventor: BOSCO PAUL N
IPC: C04B41/84
Filed: 1991-03-28
Abstract: Revêtement à base de silice et procédé destinés à l'enduction des surfaces en verre, en métal, en céramique et en plastique par la formation de chaînes simples et réticulées de polymère O-Si-O. Le revêtement comporte généralement un liant et une matière de remplissage. Le liant est un mélange en suspension aqueuse de polymères à base de silice, de silice colloïdale, et de particules d'oxyde métallique. Il comprend quatre ingrédients principaux: un silicate de métal alcalin, du gel de silice, un agent réticulant tel que le méthyltriméthoxysilane ou le tetraéthoxysilane, et de l'eau. A la suite du durcissement, le liant forme une couche amorphe qui lie les matières de remplissage à la surface. Le revêtement de protection se forme à la température ambiante sans l'apport d'énergie sous quelque forme que ce soit. On sélectionne les matières de remplissage de manière à ce que le revêtement présente une résistance mécanique, une résistance au frottement et une résistance accrue à la corrosion. On peut également sélectionner les matières de remplissage de manière à modifier la constante diélectrique du revêtement, à améliorer son onctuosité à la surface, et à modifier son coefficient de dilatation thermique. Des matières de remplissage caractéristiques sont par exemple l'argile, la wollastonite, la syénite néphélinique, la stéatite, le silex, les fibres céramiques, les fibres métalliques, les microsphères céramiques, les microsphères en verre, le dioxyde de cérium, et le trioxyde de dichrome.

Abstract: In a flat plate antenna, insertion loss is reduced significantly by providing an extensive waveguide structure at the back of the ground plane (10) of the antenna. Depending on antenna size, the waveguide may feed the antenna at one or a plurality of points. According to a preferred embodiment, the transition from waveguide to stripline is made via a coaxial connection (20), with a quarter-wave transformation, including mode suppression walls (30) to direct the energy more efficiently. Alternatively, a direct waveguide to stripline transition may be provided. The technique has wide applicability to a number of antenna designs, including single- and dual-polarization structures, and linear and circular polarization operation.

Abstract: In the case of a low-noise pressure-relief device, a radially expanding relief duct (7) is connected to an axial inlet duct section (4), which relief duct (7) is formed between two plates (5, 6) which are arranged parallel to one another and at a distance from one another and in which relief duct perforated material strips (8-13) are held between the plates (5, 6), which material strips (8-13) form concentric rings which are spaced apart radially with respect to one another. These material strips (8-13) act as shutters in order to reduce an initial pressure P0 which is present in the axial flow duct section (4) to an output pressure P1, which is present outside the radially outermost material strip (8). Each of the material strips (8-13) which form a ring (which is fixed between the two plates (5, 6) and are spaced apart from one another radially) is covered in a subregion by a covering strip (17-22), the width of the covering strips reducing in the flow direction, that is to say radially outwards. In consequence, in a material strip having a uniformly distributed hole pattern (16), the free flow cross-section which is formed by the holes which are not covered in the individual rings which are formed by in each case one material strip becomes increasingly larger from the inside to the outside. In the case of this manufacturing method, only one long, perforated material strip is required from which individual sections are cut to length for in each case one ring. This cost-effective production is also optimum in terms of strength, as a result of the strip form and the ring design of the shutters thus formed. <IMAGE>

Abstract: A compact ion mobility spectrometer (IMS) with increased sensitivity and resolution for detecting the composition of an unknown substance is disclosed. The IMS comprises a unitary cylindrical housing (42), inlet means (50, 57) for introducing sample gas, outlet means (52, 59) for withdrawing sample and drift gas, two high voltage electrodes, and a detector (70). The first electrode (60) is pulsed to inject sample ions through an opening located in a second electrode (67) which defines a drift region (90). The second electrode (67) is cup-shaped having an open end and is electrically biased to create a non-uniform electric field gradient across said drift region (90). The electric field in said drift region (90) is axial and radial resulting in an increase in ion drift velocity at the detector (70) and a corresponding increase in detected peak signal amplitudes thereby increasing resolution. A shorter drift region (90) and the absence of an aperture grid near the detector (70), which cause ion collisional losses, helps to increase IMS sensitivity.

Abstract: (1) Various gear states are selected by movement of a shift lever 2 in a longitudinal shift path 13 and the gear stage is automatically shifted from starting to the maximum gear stage in an automatic speed change position D, so that an operator can run a vehicle with increased safety and easy operation without operation of the shift lever 2. (2) When a push button switch 3 provided in the shift lever 1 is pressed during the automatic speed change running, the gear stage during the running is fixed, so that inadvertent automatic shift is prevented to be held to the optimum speed stage when a burden is varied in running on a slope or in operation. (3) When the gear stage is fixed in the automatic speed change position D and the shift lever 2 is transversely moved in the transverse shift path 14, the operator can varies the stages while varying one stage a time with the operator's will. That is, the manual speed change or transmission can be selected regardless of the automatic speed change state. The operator can switch the transmission state to the automatic transmission state or the manual transmission state in accordance with various running states and operation states to thereby improve the operation efficiency of the operation vehicle.
