Abstract: A laboratory centrifuge includes elements (10) for the locking of a lid in a closed position, which locking elements (10) include at least one strike (11) and at least one bolt (12) mobile between a locking position and an unlocking position. These locking elements (10) also include operating elements (15) including a motor shaft (16) that is coupled to the bolt (12) through transmission elements (17). The transmission elements (17) include a crank (18), extending the motor shaft (16), which carries an actuating member (19) bearing on a contact surface (12c1, 12c2) formed on the bolt (12), so that the driving into eccentric rotation of the actuating member (19) about the motor axis of rotation (16?) causes its circulation and bearing along the contact surface (12c1, 12c2) and the rotational control of the bolt (12) between its locking and unlocking positions.

Abstract: A laboratory centrifuge includes two rotating parts (10, 11) associated by translation locking elements (13) including at least one female element (16) and at least one complementary male element (15). The male element (15) is associated with elements (20) for its operation to the inactive position, which include a rotating actuator member (21) carried by one of the rotating parts (11) and which cooperates with the male element (15) to ensure, by a rotational operation of the rotating actuator member (21) about its axis of rotation (21?), the displacement of the associated male element (15) from the active position to the inactive position.

Abstract: A speed changer is used to control derailleurs using cables from a single rotating handle, the deraileurs being connected respectively to an elastic return element. The speed changer includes at least two cable-maneuvering mechanisms. The mechanism for maneuvering the cable of the rear derailleur, which rotates integrally with the handle, can cause the rear cable to loosen or tighten when the handle is rotated in one direction. The speed changer is characterized in that the rotating assembly, formed by at least one mechanism for maneuvering the rear cable and the handle, can be connected to rotate intermittently with the mechanism for maneuvering the front cable of the front derailleur which, depending on the direction in which the handle is rotated, can cause the front cable of the front derailleur to tighten or loosen.

Abstract: The invention relates to a non-cleavable, plastidial targeting polypeptide derived from a protein from the inner membrane of plant chloroplasts. Said peptide is particularly suitable for importing proteins of interest in plants.

Abstract: The invention relates to nucleic acid sequences naturally imported into a plant cell plastid, and use thereof for directing an RNA sequence of interest to a plastid, which permits, in particular, the directed expression of a protein of interest in a plant cell plastid.
