Abstract: An aircraft provided with at least one electric machine accommodated in a compartment separated from an outside environment by a cowling, the aircraft comprising a ventilation system for conveying air from the outside environment to the electric machine. The ventilation system comprises a duct connected to the electric machine and extending up to a free section, the free section being situated in the outside environment, the duct passing through a passage in the cowling, the duct extending partially into the compartment and partially into the outside environment, a free space surrounding the duct in the passage and separating the duct from the cowling, the ventilation system comprising a scoop that faces the free section without closing it off according to a vertical axis when the aircraft is on horizontal ground.

Abstract: A motor vehicle has a motorized steering lock including a bolt which locks the steering column by engaging in a recess in the steering shaft in the column. The bolt is actuated by an internally threaded slider which is carried on an externally threaded drive rod, and which cooperates with abutment surfaces formed on the bolt so as to displace the latter between its locking and unlocking positions. Besides its threaded portion, and in extension of the latter, the drive rod has a portion of reduced diameter such that, when the drive rod is rotated, the slider can slide axially along the portion of the drive rod having the reduced diameter, to a position in which its internal thread is out of mesh with the external thread of the drive rod.
