Abstract: An air gun system producing blasts resulting from the rapid opening of a main valve by movement of a piston which, as it moves out of its seat, releases air accumulated under pressure in a tank, the opening of the valve being triggered by an electric control module located on or in immediate proximity to the air gun controlled by an automatic command generator, in which the control module communicates with the command generator using two-way wireless communication.

Abstract: A sealing strip comprising a part of a configuration for fastening to a guide wall of a conveyor, the fastening configuration allowing for interlocking via elastic deformation of one of two parts of the fastening configuration.

Abstract: The invention relates to a sealing strip comprising a part (6A) of a means (6) for fastening to a so-called guide wall of a bulk conveyor, characterized in that the fastening means is a means of interlocking via the elastic deformation of one (6A) of two parts composing said fastening means.

Abstract: The subject of the invention is a guidance surface (4) designed to carry an endless conveyor surface, this surface being characterized in that the curvature of the guidance surface is determined by a horizontal roller (7) and two fixed lateral surfaces (8) located on either side of the aforementioned roller, where each lateral surface is extended beyond the bearing surface occupied by the belt, and, at least locally, at least one of the lateral surfaces is fixed to the chassis by means of rapid fixing devices so as to constitute an access door.

Abstract: The subject of the invention is a retention device for a conveyor roller, characterised in that the roller (7) is mounted on a tilting support (13).
