Abstract: A system and a method for sterilizing objects, in particular medical instruments and accessories, using gas plasma, also called ionized gas. The gases used to form the plasma do not require to exhibit an intrinsic sterilizing activity. The sterilizing properties result from the passage through an electric field generating the plasma, an electric field which is provided by microwaves, a gas stream including oxygen in molecular form (O2) or as a gas element, and atomic or molecular species capable of emitting UV radiation once they have been energized. The system and method provide the advantage of making it possible to treat heat-sensitive and thermolabile objects at temperatures less than 50° C. using gases presenting no risks for the operator.

Abstract: The invention relates to a drive mechanism for a motor vehicle sliding door, said door being integral with at least one driven arm having a sliding zone in which a pin integral with a drive element is able to slide so that said door may tack and slide between a closed position, in the vehicle bodywork plane, and an open position, in a plane approximately parallel to said bodywork plane.

Abstract: A fan in which, in order to improve straightening of the airflow, the axial length (L) of the guide vanes lies between 40 and 60 mm, and their angle of inclination &OHgr; with respect to a radial plane lies between 25 and 35°.

Abstract: The invention concerns a blade having an axial length L, expressed in meters, equal by approximately 20%, to the value of L0 given by the following formula (I): L0=0.426262−5.14288.D+23.1798.D2−44.2505.D3+30.8841.D4, D being the blade diameter expressed in meters. The invention enables to substantially reduce the blade axial space requirement, for a given diameter and for obtaining the desired performance. The invention is useful for cooling a motor vehicle engine.

Abstract: A stator device for an axial flow fan has a plurality of first stator elements and a corresponding plurality of second stator elements, the first stator elements being disposed axially rearwardly of the second stator elements so as to define an air flow slot therebetween.

Abstract: A device for fixing a motor-fan unit to a heat exchanger comprising an inner support forming a housing for fixing the motor casing of the motor-fan unit and having a lateral opening providing a passage for ancillary equipment of the motor, an outer support surrounding the inner support and adapted to be fixed to the heat exchanger and connecting armatures joining the inner support and the outer support

Abstract: A fan module with an axial flow fan and a shroud member. The axial flow fan has a hub and a plurality of fan blades, each blade extending radially from the hub. At the tips of the blades are air guide members secured to respective fan blades and concentric with the hub. Each air guide member has an axially-extending arcuate portion, and a respective lip portion extending radially outwardly from each said arcuate portion. The axially-extending portion has an axial length substantially equal to or less than the axial length of said hub. The shroud member has a surface cooperating with the air guide members in an arrangement to reduce tip vortices.
