Abstract: The invention relates to an assembly (1) for a railway vehicle, of the type comprising a first chassis (8) and a second chassis (9) which is connected to the stationary chassis (8) to tilt laterally with respect thereto on each side of a position of rest, the assembly (1) further comprising means (10) for moving the second chassis (9) laterally. The movement means (10) comprise an arm (28) for driving the second chassis (9) laterally, which arm (28) is mounted so that it can pivot about a longitudinal axis (X—X). Application, for example, to a power pick-up assembly for a tilting railway vehicle.

Abstract: A circuit for regulating the air conditioning of premises that are stationary or mobile, the premises being air conditioned by means of a conditioning unit controlled by a corrector that receives on its inputs both a reference temperature magnitude and a magnitude representative of the temperature of the premises, the circuit including a member for non-linear and non-stationary simulation of the assembly constituted by the conditioning unit and by the premises, and wherein the corrector comprises means for handling saturation in such a manner as to take account of amplitude limitation in the signal for controlling the process and the model of the process. The invention is particularly applicable to regulating the air conditioning of rail vehicles.
