  • Patent number: 11433336
    Abstract: A drive pinion of an air/oil separator of an accessory gearbox of a turbomachine, the air/oil separator being configured to be supplied at the input by an air flow to de-oil and to supply at the output, on the one hand, a de-oiled air flow and, on the other hand, an oil flow by centrifugation, the pinion being configured to drive the separator rotationally along an axis of rotation, the pinion being mounted facing a passage opening of the separator, the pinion comprising at least one guiding opening traversing the web plate defining at least one guiding surface inclined with respect to the axis of rotation in such a way as to guide along the axis an air flow to de-oil into the separator or a de-oiled air flow out of the separator via the guiding opening of the pinion.

  • Patent number: 11199203
    Abstract: The invention relates to a jet pump collector comprising a convergent duct extending along the longitudinal axis (AX) and comprising an intake opening for a fluid to be withdrawn, this convergent duct having a restriction shape terminated by a reduced end having a smaller cross-section than its intake opening. This convergent duct is equipped with a tube (17) orientated perpendicular to the longitudinal axis longitudinal (AX), this tube (17) comprising an outer portion extending outside of the convergent duct and being terminated by an intake opening (31) for a propulsion fluid, and an inner portion extending in the convergent duct and comprising a plurality of distribution openings (18, 19) for the propulsion fluid which are orientated towards the reduced end.

  • Patent number: 8343917
    Abstract: This invention relates to a combination of erythropoietin glycoisoforms, wherein such glycoisoforms may include a quantity of sialic acid ranging from 4 to 10 molecules of sialic acid per molecule of erythropoietin. The combination of glycoisoforms can be used for the treatment or prevention of sepsis, and used to prepare a pharmaceutical composition including such combination. The invention also encompasses a cell line producing a combination of erythropoietin glycoisoforms, procedures to obtain the cell line, a procedure to produce such a combination of glycoisoforms, and methods of treatment and prevention of sepsis.
