Abstract: An air centrifugation device (1), associated to an internal combustion engine (2), which includes at least one cylinder (21), provided with air by an air intake (22), and rejecting combustion gases by an exhaust orifice (23), includes a wheel (11), provided with blades to accelerate the gases by a rotational movement, the wheel is mounted on an axle (12) and placed inside an envelope (13) containing the wheel, while the envelope has preferably a circular shape, the whole system including at least one air intake orifice (14) and at least two distinct exhaust orifices (15) and (16), provided to collect separately the oxygen molecules from exhaust orifice (15), and the nitrogen molecules from exhaust orifice (16), while at least one connecting pipe (3) is provided between the oxygen exhaust orifice and the air inlet system (24) of the internal combustion engine.

Abstract: A door stop device, includes a blocking mechanism (2) and a guiding arm (1), one of these being fastened to the opening part of the door, the other being fastened to the frame, the blocking mechanism (2) including a braking element (24) pressed against a braking roller (21) which is kept in contact with the guiding arm (1), the axle (22) of the braking roller (21) being allowed to move relatively to the body of blocking mechanism (2) within specified limits, the blocking mechanism (2) also including elastic elements (26) defined to bring braking roller (21) and braking element (24), back in compression against each other. A mobile interface unit (25), allows to modulate the load generated by the elastic elements (26), increasing the load when braking roller (21) is in locked position and decreasing the load when braking roller (21) rotates freely.

Abstract: A door check mechanism which provides infinite stable retaining positions for a motor vehicle includes an articulated guided arm mounted to one of the vehicle body or the door and a mechanism mounted on the other of the vehicle body or the door such that the guiding arm penetrates the mechanism with a relative displacement between the two parts. A wedging function results from a blocking of the guiding arm by the mechanism. The mechanism includes a carriage device with a braking roller held in contact with the guiding arm and a braking element to ensure the wedging function. When a load greater than a predetermined value is exerted on the door, an axle of the roller slides along lateral guiding slots until the roller is released from the braking element, thus allowing free rotation of the roller and releases the mechanism.

Abstract: The present invention relates to a door check mechanism providing infinite stable positions with applications more specifically in the area of motor vehicles, comprising on the one hand an articulated guiding arm (1), mounted to the vehicle body or to the door, and on the other hand a mechanism (9), mounted to the other part, either the door or the vehicle body, in such a way that guiding arm (1) penetrates through mechanism (9) with a relative displacement between these two parts, the wedging function resulting from a blocking of guiding arm (1) by mechanism (9). Mechanism (9) comprises a carriage device (2), including 2 braking-rollers (21) and (22), held against each other as well as against guiding arm (1), in order to ensure the wedging function.
