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: 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).

Abstract: The invention relates to an accessory adapted to be mounted on the end of an outlet conduit (4) of an air blast device (1). The accessory is in the form of a tube having an inlet, an outlet and a central passage therethrough, the axial passage or tube being mounted coaxially to the axis of the outlet conduit. The tube has a cross-sectional area that first decreases in the direction (F) in which the air is discharged from the air blast device and a cross-sectional area that then increases in the direction F, thus forming a convergent segment (A) followed by a divergent segment (B). The air blast device is of the type having an evacuation control valve disposed between its inlet and outlet for controlling air flow contained in a chamber or reservoir.

Abstract: The invention relates to an air blast device comprising an air flow control device disposed between an inlet conduit and an outlet conduit. The control device comprises an evacuation valve (16) that controls the flow of the air contained in a rear chamber to the outlet conduit (5). The air contained in the rear chamber serves to hold a main valve (2A) in its seat (2B). This blast device is characterized in that a seat (17) of an evacuation valve is located at the level of a front face (2C) of the main valve (2). In order to evacuate air contained in the rear chamber, evacuation valve moves toward the front in the direction opposite that of the main valve (2A) as it leaves its seat (2B).

Abstract: The invention relates to an air blast device comprising an air flow control device disposed between an inlet conduit and an outlet conduit, which control device comprises a so-called evacuation valve (16) that controls the flow of the air contained in a so-called rear chamber to the outlet conduit (5), this air holding a main valve (2A) in its seat (2B).

Abstract: A monostable valve for controlling the sudden discharge of a gas contained in an enclosure. This valve comprises, in a control conduit (17), a second shutoff (18) between a closed position wherein the gas contained in the control chamber (13) cannot escape and a discharge position wherein the gas contained in the control chamber can escape, a drive mechanism (19) for rapidly moving the control shutoff to its discharge position, and a mechanism (20) for returning the control shutter to its closed position, respectively, and in that the area defined by the cross section of the discharge conduit (11) is at least constant, even increasing from the rear chamber (9) toward the outlet conduit (6) in order to limit head loss, and the main shutter (12) has low inertia.

Abstract: The invention concerns a process for fitting a gas-injecting nozzle in the wall of an installation. The process is characterized in that an external supporting surface (11) whose shape matches the so-called internal supporting surface (12) of the passage (6) provided in the bedding brick is associated with the nozzle (2); the nozzle is placed opposite the passage (6) in the bedding brick: the nozzle (2) is moved in axial translation so as to adjust the position thereof along the longitudinal axis of the passage and move the front face of the nozzle into a desired initial position; the nozzle is locked in this desired initial position; and, at least periodically, the nozzle is inserted further forwards into the passage in the bedding brick in order to compensate the wear in the front face of the nozzle. The invention can be used to prevent clogging, such as in a cement producing plant.

Abstract: A dispensing device (1) for supplying a gaseous fluid (3) to a space (2) and abruptly emptying said space (2) to deliver its contents to an apparatus (4) once the supply has been cut off. The device (1) is characterized in that to reduce the fluid pressure in a supply chamber of the device and cause a sealing member to open abruptly once the supply of pressurized fluid (3) to the device (1) has been cut off, rather than discharging the pressurized fluid (3) in the supply chamber (5) to the atmosphere and that part of the supply circuit between said chamber (5) and the cut-off assembly, the pressurized fluid (3) which previously held the sealing member against a seal seat (10) is released into a discharge duct in the device.

Abstract: The invention relates to a piston for a quick dump valve disposed for filling a space after the evacuating or dumping of that space. The piston is in the form of a plate (21) having a short peripheral flange (22), the external face of which assures only relative guidance by engaging the cylinder with a play sufficiently great as to reserve a passage (3) for the gas supplied via the feed opening sufficient to allow this gas to reach the space and a medial flange (23), the edge of which has a bearing surface the shape of which is complementary to that of the seat (9) with which it cooperates in order to close the discharge passage. The valve is particularly adapted for improving the outflow of products at the outlet of silos.
