Abstract: Dans le système décrit, le dosage de carburant est arrêté pendant la décélération du moteur et, après cessation de cette dernière, accru, pendant une brève période, par rapport au dosage nécessaire au fonctionnement normal à cet instant de marche du moteur, afin d'accélérer, au moyen de cet enrichissement du carburant, la reconstitution du film de carburant dans la tubulure d'admisssion sans affecter la composition du mélange carburant-air. Pour le dosage précis de l'enrichissement du carburant, on utilise comme critère d'interruption de cet enrichissement le signal de sortie ''mélange riche'' d'une sonde lambda (21).

Inventor: RICHESON WILLIAM EDMOND
IPC: F01L9/20
Filed: 1989-12-21
Abstract: A pneumatic powered valve actuator is disclosed and includesa valve actuator housing (19), a working cylinder within the housing having a pair of opposed contoured end faces  (53, 55), and main piston (13) reciprocable within the cylinder along an axis. The main piston has a pair of oppositely facing primary working surfaces (38, 40) contoured substantially the same as the opposed end faces of the working cylinder to mate therewith providing a small minimum volume and, therefor, a high compression ratio. A pair of air control valves (15, 17) are reciprocable along the axis relative to both the housing (19) and the main piston (13) between open and closed positions for selectively supplying high pressure air to the piston primary working surfaces. The contoured end faces each include a central opening, an outer annular flat surface, and an intermediate frustoconical surface (86) connecting the central opening and the flat surface. A piston motion damping arrangement is operable subsequent to initial piston movement and responsive to continued piston motion for compressing a trapped volume of air thereby slowing piston movement and an array of reed valves return some of the trapped air which has been compressed to a pressure greater than the pressure of the high pressure source to the high pressure source. The reed valves are adjustable to selectively control the quantity of trapped air which is returned to the high pressure source. There are auxiliary pistons (29, 31) defining variable volume chambers (91, 95) for supplying an air control valve reclosing pressure and there is a resilient bumper on each auxiliary piston for engaging and closing the corresponding air control valve (15, 17) if the pressure in the variable chamber is inadequate to close the air control valve.

Abstract: A pneumatic oscillator especially useful for generating breathable gas pulses in a resuscitator and/or lung ventilator device has a reciprocable piston or equivalent controlling a poppet valve arrangement that includes a sealing lip (32) coacting with a resilient facing (33). The sealing lip (32) provides for sharp definition of a line of contact on the resilient facing (33) and penetration of the latter by the lip (32) is limited by stop means (36), preferably abutment(s) coacting with the facing (33) adjacent to the line of contact with the sealing lip (32). This prevents wear and/or excessive indentation of the facing (33) with consequent shift of the contact line and alteration of the oscillator characteristic with time.

Abstract: A tappet assembly for use in the valve train of an automotive type internal combustion engine has a roller (18) at one end adapted to be engaged by the cam lobe of a camshaft for that engine. A spring biased piston (28,36) is incorporated in the assembly for movement into frictional engagement with the roller (18) at low engine speeds to dampen out vibrational or shaking forces present in the engine at this speed level by increasing the resistance to rotation of the roller. At higher engine speeds, the piston (28) is moved progressively away from frictional contact with the roller (18) by engine oil galley oil pressure, which increases with engine speed, to a point where the piston (28) is completely removed from engagement with the roller (18) and the roller is permitted to freely rotate at a point when the engine vibration or shaking forces are no longer present.

Abstract: The invention relates to a process for producing an atmosphere for thermal treatment of metals, formed by providing a gaseous nitrogen stream, according to which a crude gaseous nitrogen stream having a residual oxygen content is first formed by air separation by selective adsorption, to which stream is added a stream of hydrogen at least sufficient to remove, by water vapour formation by catalytic reaction, the essential part of the residual oxygen, characterised in that the following measures are employed in combination: a) the air separation by selective adsorption is carried out so that the gaseous nitrogen stream has a residual oxygen content of between 0.1% and 3%; b) the catalytic reaction to form water vapour is brought about exclusively with catalysts whose use does not involve external application of heat and c) the catalytic reaction to form water vapour is carried out in such a way that the residual oxygen content is less than 30 vpm, with a water vapour content of between 0.2% and 6%, relative to the nitrogen stream, being set up. Exclusive application to the annealing or brazing of copper, decarburising annealing of steels, nitriding of steels, and sintering of copper, nickel, copper-nickel alloys, where appropriate with lead, and copper-zinc alloy.

Abstract: Dans un procédé de cémentation d'éléments de paliers à roulement en acier au nickel faiblement allié, lesdits éléments sont cémentés dans un gaz de cémentation dissocié, refroidis, réchauffés à la température de trempe, austénitisés dans la couche de cémentation et, finalement, trempés. Afin qu'il ne se produise, lors de la cémentation, aucune fragilisation des éléments de paliers à roulement, par l'hydrogène dissocié du gaz de cémentation, lesdits éléments de paliers à roulement sont refroidis, à partir de la température de cémentation jusqu'à environ 300°C, dans un gaz inerte en mouvement, puis maintenus à cette température, de façon que suffisamment d'hydrogène dissocié s'échappe de la couche de cémentation desdits éléments. Le réchauffage subséquent de ces éléments, pour les porter à la température de trempe ou à une température de recuit intermédiaire, s'effectue avantageusement immédiatement après maintien à 300°C.
