Abstract: The invention relates to a device for coupling an agricultural implement to an agricultural tractor (1), comprising two frames (10) each provided with two base plates (11a) arranged such that each base plate (11a) of the frame (10) carried by the agricultural tractor (1) is brought into position under the base plate of the frame carried by the agricultural implement, in such a way as to form, with the latter, a pair of base plates consisting of a base plate pierced by a hole of predefined cross-section and dimensions and a base plate (11) comprising a centering member (18, 19) of decreasing cross-section starting from a base section of dimensions and cross-section matching those of the hole of the other base plate. In addition, tilting means are designed to cause, in a position where the centering members (18, 19) are partially engaged with the facing holes, a relative tilting of the two frames during which said centering members serve as the pivot for said tilting.

Abstract: The invention concerns a method and a device for variable flow heating for controlling ventilating fresh air room by room in a building. The invention is characterised in that said method provides sequential control of the air using a central management unit (48) programmed to be configured, either in a mode controlling the temperature levels in the main rooms (8) wherein it maintains the set temperature in said rooms and senses the possible complete closure of the (or all) the air outlets (5) supplying said main rooms, or at least if one of the main rooms is no longer supplied, in a mode controlling fresh air wherein it controls the opening of the air outlet(s) of each room not initially supplied during a time interval for making up for the lack of fresh air supply, and by closing the air outlets in all the other rooms during the same interval.

Abstract: A domestic air conditioning and/or heating method, particularly for apartment buildings, using an outside unit (2) and an inside unit (1) connected to one another via fluid and electrical lines (3). The outside unit (2) includes a compressor, a ventilation system and an exchanger while the inside unit (1) includes a ventilation system and an exchanger. A low pressure inside unit (1) supplies pressurized air at a pressure no higher than 8 mm and the air is bulk-fed into a false ceiling (6) forming a decompression chamber and comprises supply grills (15-17) for blowing air into each of the rooms to be served.
