Abstract: A filling machine includes a filling tube passing through a spout endpiece to delimit with the spout endpiece, part of an air return circuit. The filling tube is vertically movable and delimits an exit passage for the liquid. A control circuit is provided for moving the filling tube to a low position and driving an obturation device to open the exit passage, putting the air return circuit, when the exit passage of the filling tube is immersed in the liquid, to atmospheric pressure, moving the filling tube towards its leveling position, putting the air return circuit in communication with a pressurized chamber, and bringing the filling tube to a leveling position.

Abstract: A device for moving an object comprises a base and a platform able to receive the object; six supports each having an upper end connected to the platform and a lower end connected to the base and an actuation device connected to at least three of the supports. The upper end and lower end of each support in combination have at least five degrees of freedom. The actuation device is suited for giving predefined periodic movements to said at least three of the six supports, these three supports being called controlled supports, thus giving a periodic movement to the platform relative to the base with at least three degrees of freedom.
