摘要： A reaction gas containing methyltrichlorosilane (MTS) and hydrogen is injected into the infiltration chamber (30) in which the substrate is placed and where predetermined infiltration temperature and pressure conditions obtain. The gas entering the infiltration chamber is preheated (by plates 46) so as to bring it up to temperature before coming into contact with the substrate. The residual gas containing the remainder of the reaction gas together with gaseous reaction products is extracted from the chamber. Infiltration is performed at a temperature lying in the range 960.degree. C. to 1050.degree. C., and preferably in the range 1000.degree. C. to 1030.degree. C., under a total pressure of not more than 25 kPa, and preferably equal to 7 kPa to 12 kPa, and the concentration of silicon-containing species in the residual gas is lowered at the outlet from the infiltration chamber, e.g. by injecting an inert gas (via 70).

摘要： The downstream portion of the diverging part of the nozzle of the rocket engine is extended by an ejectable diffuser which, downstream from the zone where it is connected to the diverging part, presents a zone of smaller cross-section that acts during a first stage of flight in the presence of significant outside pressure to recompress the flow of hot gases and to prevent a flow separation from appearing along with the wall of the diverging part. The ejectable diffuser may have a streamlined throat which constitutes the zone of smaller cross-section.

摘要： The centrifugal pump with an open-faced impeller comprises at least one open-faced impeller having blades placed inside a casing defining both a delivery pipe and a suction pipe facing the base of the blades situated in the vicinity of a central shaft for driving the impeller. An active axial balancing system for the rotary assembly is integrated in the impeller and comprises a balancing chamber interposed between the rear face of the body of the impeller and an outer rear portion of the casing, the impeller itself acting as the balancing turntable. A shroud-forming intermediate part is prevented from rotating relative to the casing and is interposed between an outer front portion of the casing and the impeller, a cavity is formed between the outer front portion of the casing and the intermediate part to receive a back pressure of predetermined value serving, in operation, to maintain small clearance without contact between the intermediate part that is prevented from rotating and the blades of the impeller.

摘要： The retractable-gasket ball valve includes sealing means fixed on the valve body, and including, in particular, a gasket for providing sealing between the shutter member and the valve body when the shutter member is in a closed position, and further including a slide for causing said sealing means to move between a retracted position which is also a rest position in which the sealing means is spaced spart from the spherical shutter member, and a contact position in which the gasket is pressed against the shutter member. The valve includes a first resilient element of low stiffness which tends to separate the sealing means from the shutter member when the valve is brought to its open position, and a second resilient element of relatively greater stiffness which is put under tension by the slide a few degrees before the mechanical closure position of the valve when the gasket is in contact with the shutter member, and which exerts control pressure on said gasket in contact with the shutter member.
