The invention is an emergency closing system (100) for drainage pipes (T), comprising: a shutter balloon (200) inserted and constrained inside a pipe (T) and normally in a totally or partially deflated configuration; a compressed air tank (300); a compressed air supply line (400) connected to said tank (300); a compressed air outlet line (500) connecting said tank (300) to said shutter balloon (200); a solenoid valve (510) mounted on said outlet line (500) and normally closed; an air valve (520) mounted on said outlet line (500) and normally closed; an ON/OFF control (600) for opening/closing said solenoid valve (510), wherein said control (600), when activated, opens said solenoid valve (510), with said air valve (520) closed, in such a way that the compressed air inflates said shutter balloon (200), which occludes said pipe (T).

The invention is a new electrical connector (C), comprising at least one main body (1) suited to be mechanically coupled with a corresponding main body (1') of a corresponding electrical connector (C'), an electrical contact pin (3, 3') housed in said main body (1), a locking element (4) suited to lock the conductor of the cable in the contact pin (3, 3'), suited to fit around said contact pin (3), and wherein the connection of said locking element (4) to said contact pin (3, 3') results in that said locking element (4) is completely or partially inserted into at least one generically linear opening or slot (3f) or notch of said contact pin (3, 3').

Access chamber made of a plastic material, comprising two parts (C1, C2) made of different materials, and wherein the first, upper part (C1) comprising the edge (Cb) on which the cover (T) rests and the upper part (C1p) of the side walls (C1p, C2p) is made of virgin, non-recycled plastic, and wherein the second, lower part (C2) comprising the bottom (Cf) of the chamber and the lower part (C2p) of the side walls (C1p, C2p) is made of a recycled plastic material.

The invention is a dental implant (100, 101, 102) comprising a first threaded endosseous portion (200) having a central axis (X) and joined, so as to form a single piece, to a second extra-mucosal portion (300), which in turn is provided with a truncated cone-shaped portion (340) having an internally threaded axial hole (342) in which a fixing screw (510) for placing a prosthesis (500) is screwed. The implant also comprises a connector (400) comprising a first threaded portion (410) suited to be screwed into said hole (342) of said extra-mucosal portion (300) and a projecting portion (420). Said connector (400) is axially perforated and the inside of its axial hole (430) is completely or partially threaded so as to allow a fixing screw (610) for placing a prosthesis (600) to be screwed therein. The combination of said projecting portion (420) of the connector (400) and said truncated cone-shaped portion (340) defines a shape or surface suitable for coupling with said prosthesis (600).
