Abstract: An architecture for supplying air to a high-pressure compressor of an auxiliary gas generator from a pressurized cabin of an aircraft, comprising: a load compressor rotationally driven by a common rotation shaft providing a mechanical coupling between the high-pressure compressor and a high-pressure turbine of the auxiliary gas generator and supplied by an outside air intake; a first regulation valve assembled at the outlet of the load compressor to control all or part of the air flow delivered by the load compressor; a second regulation valve assembled at the outlet of the pressurized cabin to control the air flow drawn from inside the pressurized cabin; a mixer receiving the outputs of the first and second regulation valves to add the air drawn from inside the pressurized cabin to all or part of the air delivered by the load compressor.

Abstract: An architecture for supplying air to a high-pressure compressor (140) of an auxiliary gas generator (14) from a pressurized cabin (12) of an aircraft, comprising: a load compressor (16, 52) rotationally driven by a common rotation shaft (146) providing a mechanical coupling between the high-pressure compressor and a high-pressure turbine (144) of the auxiliary gas generator and supplied by an outside air intake (18, 58); a first regulation valve (22) assembled at the outlet of the load compressor to control all or part of the air flow delivered by the load compressor; a second regulation valve (22) assembled at the outlet of the pressurized cabin to control the air flow drawn from inside the pressurized cabin; a mixer (24) receiving the outputs of the first and second regulation valves to add the air drawn from inside the pressurized cabin to all or part of the air delivered by the load compressor; and a third regulation valve (26) assembled at the outlet of the mixer to control the air flow injected into the

Abstract: This toothpaste contains reagents for controlling the tooth brushing time by the change in color occurring after a predetermined brushing time. It contains essentially a citrate/citric acid buffer having a molarity of 0.07 to 0.35 M and a pH of 4 to 5.5 in the proportion of 10 to 50%, and chlorophenol red in the proportion of 0.02 to 0.1%.

Abstract: A self-propelled carriage for inspecting the primary vessel of a fast reactor is capable of displacement within the interspace between the primary vessel and the containment vessel in order to inspect and test any predetermined zone of the primary vessel, the carriage being associated with a drive mechanism and applied against the oppositely-facing wall of the containment vessel. The carriage is suspended from a composite cable actuated by a handling apparatus for introducing the carriage into the interspace and withdrawing it therefrom. The composite cable supplies electric power as well as the different fluids required for positioning and operation of the inspection devices which are mounted on the carriage.
