Abstract: Equipment (60) for the surface emission of infrared radiation, comprising a thermally insulated wall (62) forming a tunnel (63), and a number of unitary surface emission devices (1) each arranged with respect to and in the thermally insulated wall (62), characterized in that, in combination: each unitary surface emission device (1) comprises a box (21) arranged in the thermally insulated wall (62) and in which there is formed an opening (22) facing the downstream face (30) of the catalytic combustion wall (3); a number of transparent ceramic window panes (23) are mounted in such a way as to form, with the various seats of catalytic combustion (2), a respective number of circuits (24) for discharging the flue gases (25); the thermally insulated wall (62) comprises a secondary surface emission metal sheet (64) in a direct heat-exchange relationship with the tunnel (63) and forming with the remainder of the wall (62) a channel (65) for the flat circulation of burnt gases (25).

Abstract: Device (1) for the surface emission of infrared radiation, comprising a combustion chamber (2) having a wall (3) made of refractory material, permeable through its thickness, suitable for the passage of a mixture (4) to be burnt (combustible gas (30) plus oxidizer gas (31), for example air) from its upstream face (3a) to its downstream face (3b), and the internal developed surface of which is coated with a catalytic combustion material, and an upstream chamber (5) supplied on one side with the mixture to be burnt and closed on the other side by the catalytic combustion wall. The combustion chamber (2) includes at least one heat exchange wall (6), placed upstream of and facing the catalytic wall (3), in order to receive via its downstream face (6b) at least most of the heat radiated by the upstream face (3a) of said catalytic combustion wall, said heat exchange wall made of refractory material also being permeable through its thickness and suitable for passage of the mixture (4) to be burnt.

Abstract: A process for reconstituting or reconstructing a composite object having a defect which affects at least its surface includes: (a) placing at least one added piece or material, the shape and dimensions of which are matched to those of the defect, in or on the defect, the piece or material including mechanically strong, continuous or staple fibers; (b) placing a polymer material in or on the defect to obtain a plastic matrix in which the fibers are distributed; (c) placing a gas-drain for draining the gases given off by the plastic matrix and a cover for extracting the gases, in succession and one on top of the other, on the added piece, which together with the rest of the object form an enclosure which is sealed with respect to the external atmosphere and circumscribes the defect and the added piece; and (d) while evacuating the sealed enclosure, heating the added piece using a radiant source, the emission from which includes infrared radiation, and placing the source with respect to the defect so as to irrad
