Abstract: An arrangement for an aircraft turbine engine, including a shaft and a follower element rotatably coupled to the shaft by a spline connection, the arrangement including upstream and downstream connections for radially centring the follower element relative to the shaft; means for spraying a lubricant into a collection cavity; a passage for receiving lubricant, which passage opens into the collection cavity and into a cavity for lubricating the splines which is partially defined by the upstream and downstream radial centring connections; and a passage for discharging lubricant, which passage opens into the cavity for lubricating the splines and outside the arrangement.

Abstract: A propulsion system includes a drive shaft that rotates about an axis, a fan, a fan shaft that drives the fan about the axis, a reduction mechanism coupling the drive and fan shafts, a compression section driven by the drive shaft, and an inlet channel that extends between the fan and the compression section. The inlet channel includes inner and outer ferrules delimiting an air inlet flow path, the inner ferrule having a minimum radius. The reduction mechanism includes two reduction stages including two or more planet gears circumferentially distributed around the axis, each planet gear including a first portion meshed with the drive shaft and a second portion meshed with the fan shaft and being mounted fixed with respect to the inner ferrule and having a maximum radius greater than the minimum radius such that the air inlet flow path extends partly between the two or more planet gears.

Abstract: Fluid product dispenser having a reservoir (R) with a threaded neck (R1) forming an external helical thread (R2), a closure element (T) having a threaded skirt (F1) forming an internal helical thread (F2), and a band (H) engaging around the threaded skirt (F1). The skirt has tabs (F11), each forming a segment (F21) of the internal helical thread (F2). The fastening member (F) has an angular indexing mechanism for positioning it with respect to the external helical thread (R2) with a determined angular orientation, and the segments (F21) of the internal helical thread (F2) of the threaded skirt (F1) come into corresponding threaded contact with the external helical thread (R2) of the neck (R1) in the final assembly position.

Abstract: A assembly for dispensing a fluid product having a first fluid-product dispenser with a first reservoir, a first dispensing member, such as a pump, provided with a first dispensing head and a first pusher, and a second fluid-product dispenser with a second reservoir, a second dispensing member, such as a pump, provided with a second dispensing head and a second pusher. The second dispenser is removably mounted on the first dispenser so as to prevent the actuation of one of the two dispensers.

Abstract: Fluid product reservoir having a neck defining an opening, the neck having an upper annular edge defining an outer ridge and an inner ridge, the opening being defined by an inner wall connected to the upper annular edge by the inner ridge. At least one cutout is provided at the upper annular edge, this cutout extending on the inner wall, interrupting the inner ridge, but does not extend as far as the outer ridge, such that the upper annular edge is continuous over its entire periphery, including at the cutout, this cutout further forming a base defining a ridge with the inner wall of the opening.

Abstract: A fluid dispenser device having a fluid reservoir (10), a pump (20) mounted on the reservoir (10) for selectively dispensing the fluid, and a dispenser head (30) connected to the pump and incorporating a dispenser orifice (31). The device includes at least two laterally-actuated elements (40, 50) distributed around the dispenser head (30), the laterally-actuated elements (40, 50) being displaced simultaneously in a direction that is approximately transverse to the central axis of the device, and each co-operating with a peripheral edge (11) of the reservoir (10) so as to exert an axial force thereon.

Abstract: A fluid dispenser device comprising a body (10) defining a dispensing orifice (11), and a reservoir (20) containing one or more doses of fluid, said reservoir (20) having a piston (25) which, at rest, forms a leaktight stopper, said device being characterized in that it further comprises a resilient element (30), such as a spring, that co-operates firstly with said reservoir (20) or with said piston (25), and secondly with a cocking member (40), said cocking member (40) being mounted to be movable manually relative to said body (10) so as to compress said spring (30), and being mounted to be lockable relative to said body (10) in at least one locked position in which said spring (30) is compressed, said device including at least one triggering member (50, 51) adapted to release said spring (30) so as to move said at least one piston (25) relative to said reservoir (20) so as to expel a dose of fluid.

Abstract: A process is disclosed for the preparation of a hydroxyl apatite material by means of hydrothermal conversion using as starting material a calcitic skeleton which has been purified of organic substances. The conversion is carried out under saturated steam pressure, preferably at a temperature in the range of from 100.degree. C. to 250.degree. C. The influence of the reaction, or rather the defect density of the materials is preferably achieved by the addition of fluoride ions. In addition, the adaption of the material to differing implantation areas as hard tissue replacements as well as the preparation of workable compact implants is described.
