Abstract: A satellite propulsion system comprises: at least one tank containing a propulsion reagent, and at least one tank containing a pressurizing gas that pressurizes the propulsion reagent, at least one transport means for transporting the pressurizing gas from the pressurizing gas tank to the propulsion reagent tank, the transport means comprising at least one opening allowing a continuous leak-off of pressurizing gas, and at least one device intended, after the satellite has entered operational orbit, to isolate a zone comprising the opening from the rest of the propulsion system.

Abstract: A material is provided having a lamellar, non-centrosymmetric macroscopic structure, essentially consisting of a mixture of at least two populations of objects that are heterogeneous in blocks along an axis, each object consisting of at least two blocks, characterized in that each of the objects is connected to adjacent objects via interactions that involve at least two mutually incompatible blocks of the object and two blocks that are compatible one-to-one with the first of the blocks, and mutually incompatible along the chain of each one of said adjacent objects. The objects can be, in particular, block co-oligomers or copolymers.

Abstract: Novel compounds, having an azlactone function, of formula (I), to be used as multifunctional coupling agents, and a method for coupling a biomolecule and a target molecule using such a compound are described. A diagnosis reagent, a kit for implementing the coupling method, a method for separating, detecting and/or characterizing at least one molecule of interest, and a composition including a novel compound are also described.

Abstract: A device for dispensing a fluid or pasty product includes a dispensing member fixed to a container including a neck and a cap, about the dispensing member, wherein the neck includes a ramp and an edge of the cap includes a ramp, the ramps being mutually mobile in rotation between a dispensing position wherein the dispensing member can be actuated and a locking position wherein the ramps prevent the dispensing member from being actuated.

Abstract: The invention concerns a device for dispensing a fluid or pasty product comprising a dispensing member (4) fixed to a container (2) with a sealing ring (10), said container (2) including a neck (7), said dispensing member (4) having mounted thereon a push-button (3) capable of being depressed to operate said dispensing member (4), said push-button including a dispensing orifice (14) enabling a product to be expelled when said dispensing member (4) is operated, and a cap (5), integral with said push-button (3), upon translation about a median axis of the dispensing device towards said container (2), an edge of said neck (7) including a ramp (8), and edge of the cap (5) including a ramp (11), said ramps (8, 11) being mutually mobile in rotation between a dispensing position wherein the dispensing member (4) can be actuated and a locking position wherein they prevent the dispensing member (4) from being actuated.

Abstract: An electromagnetic linear actuator having a stationary annular assembly with a magnetic outer shell and a magnetic inner core. Monostable or bistable control components may be mounted interchangeably between the outer shell and inner core. An assembly which is moveable in the axis of the annular assembly includes two magnetic plates which face the extremities of the annular assembly and a rod which is mounted so that it can slide inside the core. The first core is made of a material chosen for its frictional characteristics. The actuator may be used to control the valve of a regulator in the fuel supply circuit of a satellite engine.
