摘要:
A flexible sheet material of thickness less than half a millimeter for making tensioned structures such as false ceilings, in particular, the material including microprojections formed by displacing the material from which it is made, said material presenting an acoustic absorption coefficient which is higher than that of the same material without said projections.

摘要:
The invention concerns a false wall element comprising a stretched fabric in a frame with lateral edge provided with means catching the edges of said fabric, said lateral edge comprising a rigid profiled section forming a free edge curved in the plane, with curvature corresponding to that of a part of the edge of said fabric fastened on said curved edge. Said false wall elements are used for making curved stretched suspended false ceilings and stretched false walls with curved profile.

摘要:
A fully-featured minimalist backpack including a back portion having at least one main pocket, a thoracic strap extending from a bottom of the back portion, and two shoulder straps extending from a top of the back portion. The shoulder straps may each be connected to a front portion of the thoracic strap. The thoracic strap may have one or more pockets. A slot for a personal electronic device may be included in the main pocket. Various configurations for retaining eyeglasses and earphone cables may be included. The thoracic strap may have distal ends that are magnetically attachable to each other. An elastic band may be located between the shoulder straps. One or more secondary or hidden pockets may be included.

摘要:
This invention relates to a system for supplying fuel to an aircraft engine, wherein an electronic computer subdivides the stroke of the throttle lever into a plurality of zones, in each of which the thrust of the engine varies between a maximum value and a minimum value. The computer ensures a modulation of the thrust about the value corresponding to that displayed by the position of said throttle lever. No mechanical link is provided between the lever and the fuel admission valve.
