Abstract: A steering column mechanism (10) comprises a lower body (14), an upper tube (16) that is movable depthwise relative to the lower body (14) along an extension and retraction path, in a direction of retraction and in a direction of extension opposite the direction of retraction, and a locking mechanism (34) for locking the upper tube (16) relative to the lower body (14), movable between a locked position and an unlocked position. A retractable stop (58) is movable relative to the lower body (14) and relative to the locking mechanism (34) between an active position and a retracted position. In the active position, the retractable stop (58) limits the travel of the upper tube (16) in the direction of retraction to an adjustment stop position, whereas in the retracted position, it does not interfere with the upper tube (16). The retractable stop (58) is linked to the locking mechanism via an interlock (65) in such a way as to be in the active position when the locking mechanism (34) is in the unlocked position.

Abstract: A device for indirect cold production for a compression, absorption, adsorption or chemical refrigerating system comprises an evaporator in heat exchange relationship with the fluid to be cooled in one or more condensers, themselves in direct heat exchange relationship with the evaporator or the refrigeration circuit reactor, circulation between the evaporator and the condenser being established by gravity flow using a phase change fluid and separate vapour and liquid pipes.

Abstract: A cooling plant bringing into play a reaction between a solid and a gas, comprises at least two solid-containing reactors connected to an evaporator and a condensor by means of tubes in which the gas flows. Means are provided for cooling the reactor. Said means comprise a heat exchanger filled with a refrigerating agent and connected by tubes to a condensor in heat exchange arrangement with a fan.
