Abstract: Modular section for tracks, in particular cycling paths or the like, characterized in that it comprises at least one base module (2) having a lower surface (2a) which can be anchored to a constraint surface such as a ground or a road surface and an upper surface (2b) defining a supporting plane and lying at a higher level with respect to the constraint surface; at least one connection module (3) stably connected to a side edge (L) of the base module (2) and configured to connect with a respective junction element (4) or to a corresponding connection element (5) of at least a modular section (1) of adjacent tracks; the base module (2) and the connection module (3) also having respective front and/or rear connecting means for coupling to respective base modules (2) and connection modules (3) to realize a succession of modular sections (1) mutually connected along a development direction of the track.

Abstract: An antenna for submarines comprises a base member extending along a main direction of extension between its bottom end, which is fixable to a structure of a submarine, and its top end, at least one movable stem, juxtaposed with the base member and extending along the main direction of extension between its bottom end and its top end, electrical connection means between the stem and the base member and movement means by which the stem is moved relative to the base member along the main direction of extension between a lowered position and a raised position. The connection means comprise a wire-shaped element extending between two end portions connected to the stem and to the base member, respectively, where at least the end portion connected to the stem is equipped with an underwater connector.
