Abstract: A self-contained emergency breathing apparatus is provided comprising a hood (10) surrounding substantially sealingly the head of a person and comprising an assembly (18) formed of a cylinder of breathable gas at high pressure, a pressure reducer, an ejection nozzle, a duct for sucking the air contained in the hood and mixing this air with the ejected gas and carbon dioxide absorption means. The apparatus may be stored for a long period of time and be used for a short period of time for escaping from a zone having risks of asphyxiation.

Abstract: An apparatus for the thermal treatment of a thin part (1) includes a thermal light source including linear lamps (17) of very high unitary power such as "tungsten-halogen" lamps, and a housing (2) containing the part to be treated. The apparatus includes inside the housing (2) a chamber (4) delimited by the sidewall and the bottom (3a) of the housing as well as by a silica window, making it possible to create about the part to be treated particular conditions for thermal treatment. Within the treatment chamber there is arranged a compensation means (22a) for the thermal losses of the part to be treated. The thermal light source is configured like a light box (16a) by superimposing several modules (43) having a polygonal cross-section.
