Abstract: The invention relates to a method for the selective purification of aerosols. The invention consists in electrostatically collecting all of the particles present in an aerosol, but with separation of the mechanisms on one hand for charging particles by unipolar ion diffusion in order to charge and then collect the finest particles, and on the other hand for charging particles by means of Corona discharge in order to charge and then collect the largest particles on a substrate different from the substrate for collecting the finest particles.

Abstract: An assembly for picking and transporting nano-objects, comprises a cassette having first and second components, which are provided with means of mutual assembly and with means for holding the filter. The first and second components define, when the components are in an assembled configuration, a cavity in which the filter is housed and held therein. The means of mutual assembly comprise first clipping means secured to the first component, second clipping means secured to the second component and able to collaborate with the first clipping means so as to clip the two components together. A picking device comprises suction means to which the cassette is able to be removably attached. The first and second clipping means are configured such that they are not accessible from the outside when the components are in the assembled configuration with the cassette fixed to the device.

Abstract: The invention relates to a support (5) for a cooking vessel, comprising a plurality of wings (25). The wings (25) are arranged in such a way as to at least partially define a free site (27) to be positioned over a burner (3) of a hot tray (1). Two consecutive wings (25) from the plurality of wings (25) define an opening (37) between each other. The support (5) for a cooking vessel is characterized in that an outer surface of each wing (25) has a concave form, and in that the concavity of the outer surface (29) of each wing (25) is oriented away from the free site (27).

Abstract: Gas burner (1) comprising a mixing chamber (5); a burner head (19) provided with a plurality of openings (22) in fluidic communication with the outside, the burner head (19) constituting part of the wall of the mixing chamber (5), the burner head (19) comprises: a central hole (18); a first zone (23) comprising openings of a dimension of between 0.8 and 1 mm; a second zone (25) surrounding the first zone (23) and comprising openings of a dimension of between 0.8 and 1.5 mm; a solid annular intermediate zone (31) situated between the first and the second zone (25); the burner head further comprising an annular shoulder (21).

Abstract: The present invention relates to a compact barbecue, which can be connected to a cylinder or cartridge (2) of gas for cooking food, comprising a base (10), a combustion chamber (20) connected to the base (10) and including a front opening (23), a radiating gas burner (3) arranged inside the combustion chamber (20) opposite the front opening (23) thereof, characterized in that the barbecue (1) is foldable, the base (10) being movable relative to the combustion chamber (20), from a first so-called functional position (P1), in which the base (10) is arranged substantially transversely in relation to the combustion chamber (20) and ensures the stability of the barbecue (1) on the ground, and the front opening (23) of the combustion chamber (20) is cleared towards the outside, to a second so-called transport position (P2), in which the base (10) is arranged substantially longitudinally relative to the combustion chamber (20) and closes the opening (23) of the combustion chamber (20), wherein the combustion chamber

Abstract: The device comprises a target member (4) and a support (1) for supporting the target member. The support includes a receptacle head (12) for the target member, including a housing (15) open to the outside via an outwardly flared frustoconical seat (16). The target member includes a flange (42) having a spherical annular lateral surface adapted to bear tangentially against the seat (16), and a plate (45) upstanding perpendicularly on the flange in an equatorial plane an imaginary sphere (44) of which the lateral surface of the spherical annular flange is part. The plate has two parallel plane retroreflecting faces and a hole (46) passing completely through it and centered on an axis perpendicular to the faces of the plate and passing through the center of the spherical surface, and the hole is open at both ends via a bevel (461).
