Abstract: A flammable gas diluter includes: a dilution vessel comprising an outer envelope defining a longitudinal flow passage from an inlet to an outlet; at least one air inlet for directing a flow of air into the inlet of the diluter; and a flammable gas inlet arrangement. The dilution vessel has a plurality of gas flow directing formations arranged between the flammable gas inlet arrangement and the outlet, each being at a different position along a length of the dilution vessel. At least one of the plurality of gas flow formations is an inwardly directing gas flow formation for directing gas flow away from the outer envelope and at least one of the gas flow formations is an outwardly directing gas flow formation for directing gas flow towards the outer envelope.

Abstract: The present invention is an improved footstep for an aircraft galley or similar monument that is retractable into the galley when not in use. The overall size of the footstep is significantly reduced by the use of a spring loaded detent mechanism. The present invention is designed to allow the footstep to remain in the deployed, horizontal position by means of a spring and plunger that cooperate to create a detent or over-center position. Further, the present invention permits the footstep to automatically return to the stowed position by virtue of the spring and plunger detent system.
