The invention relates to a method for at least partially deconstructing a flat display screen (10), the screen (10) comprising: - a substantially flat faceplate (11) comprising four side edges and a visible part (12) on a front face of the screen (10), said visible part (12) being intended to display images, - a frame (13) that mounts the faceplate (11) by partially covering at least the front face and two side edges, the method comprising steps of: - disposing (100) a single screen (10) on a holding device (20), and - clamping (110) the single screen (10) to the holding device (20). The method is essentially characterized in that it also comprises a step of: - effecting plastic deformation (120) of the frame (13) while maintaining the integrity of the faceplate (11).

The invention relates to a method for at least partially dismantling a flat screen, said screen (10) comprising: a substantially flat base (12); connectors (50) solidly connected to the screen (10); back-light lamps (11) connected to at least one connector (15) and solidly connected to the screen (10) by means of said connector (15); at least two lateral edges (R1, R3); and at least one plate (30) substantially perpendicular to at least one of the lateral edges (R1, R3), said plate (13) covering the connectors (15) and the end of the lamps (11) connected thereto and being provided with openings (14) for the passage of said lamps (11) to the connectors (15). The method comprises the following steps: when the screen (10) comprises a faceplate, the faceplate is first removed (100) in order to reveal the lamps (11) and the above-mentioned plate (13), and the lamps (11) are dismantled (120) from the screen without breaking same.

The invention relates to a method for the production of glass fibres, comprising the following steps: supplying the starting ingredients including silica, a material that can provide a supply of alumina and at least one flux; melting the starting ingredients at a temperature of between 1300°C and 1500°C; subjecting the molten mixture to fibre forming; and collecting the fibres thus obtained. According to the invention, the above-mentioned material that can provide a supply of alumina consists of coal fly ash. The invention also relates to the mineral fibres that can be obtained by this method.

The invention relates to a method for cold-cutting a lamp (21) having an inner pressure that is lower than the atmospheric pressure and containing a pollutant. Said method includes: keeping the lamp in position; cutting (102) said lamp at at least one cutting point; prior to cutting, submerging (110) said cutting point in a liquid or pasty composition; keeping said cutting point submerged during the cutting; and suctioning (130) part of the composition into each cut-off portion (26A, 26B). Said method is essentially characterized in that the composition is dilatant and has a temperature no lower than the pour point thereof, prior to the cutting step. The method is also characterized in that, after the cutting, the temperature of the dilatant composition (104) is reduced to a temperature lower than the pour point thereof, such as to increase the viscosity thereof and create a sealed stopper.

The invention relates to cleaning equipment for cleaning a tank intended for storing inflammable products and that defines an internal volume (Vint) provided with an opening, this equipment comprising a shutter (1) suitable for closing the opening, a flexible hose (2) that passes through the shutter (1), a trolley (3) sized in order to be able to be introduced into the internal volume (Vint) of the tank, and a cleaning head (4) borne by the trolley (3), connected to the flexible hose (2), and designed in order to spray a cleaning liquid delivered at high pressure by the flexible hose (2). The equipment of the invention also comprises a rod (5) connected to the trolley (3) and passing through the shutter (1), and the trolley (3) comprises a chassis (30) provided with rolling members (300) so as to be able to adopt, in the tank, a position controlled by an action exerted on the rod (5) in the space (Ext) external to the tank.
