Abstract: Described is a system for the emergency evacuation of persons from a structure, such as a building, ship, raised platform, stadium or the like, comprising supporting means, designed to be positioned at a window of said structure for the emergency evacuation from said structure; at least one load-bearing structure, coupled with said supporting means, comprising in turn a plurality of modules, each comprising two inflatable longitudinal tubular elements positioned parallel to each other, said modules being positioned in series with each other; a slide having a surface on which the persons evacuated from said structure can slide, said slide being interposed between said two inflatable longitudinal tubular elements of said modules; and a pneumatic inflation system for the selective inflation of said two inflatable longitudinal tubular elements of said modules.

Abstract: The present invention relates to an emergency evacuation system (S) from a building (E) lying on a ground (T) and having one or more windows (F), comprising at least two evacuation units (1), each comprising in turn support platform (10) fixable to the frame of a respective window (F), a slide (11), having at least one module inflatable on command, wherein each slide (11) has a first end (110) coupled to the support platform (10) on which it is installed, and a second free end (111), and wherein each slide (11) is capable of passing from a closed position to a unfolded position; wherein a first of said evacuation units (1) is arranged at a lower height than a second evacuation unit (1) such that, when said slide (11) of said second evacuation unit (1) is in said position unfolded, said second end (111) free of said slide (11) of said second evacuation unit (1) is coupled to said support platform (10) of said first evacuation unit (1), wherein each evacuation unit (1) comprises at least one hinge (130, 13), an

Abstract: A filtering gate for the protection of a site includes two boxes arranged side by side and forming two corridors allowing communication between an inside of the site and an exterior of the site. A first and a second pair of leaves are located at an inside front and an external front, respectively, of the boxes arranged side by side, the leaves of each pair being movable parallel with respect to each other and transverse to a flow passing in the corridors, each leaf being movable independent of the other leaf of the pair, between a first position in which it blocks passage through one of the corridors and a second position in which it blocks passage through the other of the corridors.
