Abstract: A method and a device for making a dispersion or an emulsion (41) from at least two fluids known to be unmiscible, the fluids constituting a dispersed phase (40) and a dispersing phase (44), the dispersed phase (40) being driven through a porous body (24) into the dispersing phase (44). The invention is characterized in that the porous body (24) is vibrated by a mechanical, electrical or magnetic excitation.

Abstract: A vacuum cartridge, in particular for an electrical protection apparatus such as a switch or circuit breaker, comprising an enclosure of appreciably cylindrical shape closed by two end-plates, two contacts extending axially inside the enclosure, at least one of which contacts called the movable contact is connected to an operating mechanism and is slidingly mounted between a closed position of the contacts corresponding to a rest position of the apparatus and a position in which the arcing contacts are separated and form an electric arc between them, separation of the contacts resulting in breaking of the electrical circuit, and a means for producing an axial magnetic field for diffusion of the arc in the arc formation area. The cartridge comprises means for speeding up cooling of the contact material in liquid form flowing on the contact surface of said arcing contacts during breaking.
