A dynamic power cable (100) is described, comprising: - at least one cable core (110) comprising an electric conductor (115) surrounded by an insulating system (200) ; - a metal layer (120) in the form of a metallic foil (121) folded around the cable core (110) along a longitudinal direction (A), wherein the metal layer (120) is made of a copper-tin alloy having a tin content of from 0.5% to 14% by weight, with respect to the alloy total weight.

A spongy structure (1) is described, comprising a reticular body (2) having a plurality of cells (3) interconnected with each other and extending three-dimensionally over a volume (V); the reticular body (2) is composed of a base unit which is repeated for a plurality of times in the volume (V) defining a regular structure.

Delivery nozzle (10) to regulate a delivery flow towards an interior of a tub of a swimming pool, comprising a hollow body (20) comprising a longitudinal through opening (30) adapted to allow the passage of said delivery flow, a stem (25) arranged within said through opening (30) along a longitudinal axis (L), a hollow threaded set screw (60) comprising a head (63) adapted to be engaged by a screwing tool, comprising a longitudinal through opening (70) adapted to allow the passage of said delivery flow, an external threaded portion (64) adapted to be screwed with a threaded wall (46) arranged within the longitudinal through opening (30), so as to switch said hollow threaded set screw (60) from a more screwed configuration to a less screwed configuration along said longitudinal axis (L), wherein said longitudinal through opening (70) of said hollow threaded set screw (60) comprises a housing portion (72) adapted to house at least a portion of said stem (25), wherein said delivery nozzle (10) is adapted to switch from an open configuration to a closed configuration of the delivery flow.

A corewinder (100) to form a core (200) for tissue paper logs (300) from cardboard strips (201, 202) is described, the corewinder (100) comprises an unwinding station (10) adapted to unwind two or more reels (11, 12) of a cardboard strip (201, 202); a forming station (20), placed downstream of the unwinding station (10) and adapted to spirally wind at least an upper strip (201) and a lower strip (202) being unwound from the reels (11, 12) one on the other, joining them to form a tube (203); a cutting station (30) placed downstream of the forming station (20) and configured to cut the tube (203) being formed to obtain a core (200); the corewinder (100) also comprises a dispenser assembly (40) for an adhesive film (41), configured to unwind an adhesive film (41) connectable to said upper strip (201) to obtain a core (200) at least partially covered by said adhesive film. A process to make a core (200) at least partially covered by such an adhesive film (41) and a tissue paper log (300) comprising such a core (200) are also described.
