Abstract: A system and method for transferring a satellite from an initial orbit into a mission orbit. The method includes anchoring to the satellite of an external unit having a tank containing a reserve of propellants. The system includes an autonomous spacecraft having an electric propulsion module and a small internal reserve of propellants, located in a parking orbit close to the initial orbit. The spacecraft with the external unit attached to the satellite is docketed in an initial orbit, to produce a fluidic connection of the propellant tank of the external unit to the propulsion module of the spacecraft. The external unit and satellite is transferred into the mission orbit by the electric propulsion module of the spacecraft supplied with propellants directly from the external unit, thereby releasing the satellite into the mission orbit.

Abstract: Disclosed is a space vehicle, such as a satellite, the vehicle including: at least one equipment-carrying module for carrying equipment of the vehicle; at least three posts extending at least partially in the same longitudinal direction and on the periphery of the equipment-carrying module, each post being provided with at least one releasable locking device; and a reinforcing structure which rigidly connects each post transversely to at least two other posts.

Abstract: The invention concerns a press for blow-molding. This press (10) comprises a frame (11) on which there are mounted two movable plates (12, 13), each supported a half-mold (14, 15) and actuated by a mechanism for opening and closing the mold, which is formed of the two half-molds. Each of the movable plates is attached to a beam mounted on two axles (19, 20) so that it slides along these axles in opposite directions. The opening mechanism essentially consists of an actuator, two transmission blocks (29) and two pairs of connecting rods (33) connected to said movable plates. When the actuator drives the transmission blocks (29) in the direction of arrow A, the rods cause the mold to close. When the transmission block turns in the direction of arrow B, displacement of the rods causes the mold to open. The invention has applications for high speed molding presses in which the mold must be opened in rapid cycles.
