Abstract: A method for transmitting data stream packets within a wireless communication network, includes the following steps: at at least one node: computing, from the signatures Si of the streams Fi to which the node has subscribed and for each of these streams Fi, reserved resources RBres wherein there is no collision, and resources RBcomp potentially in competition, wherein collisions are possible, checking whether the current resource RB is reserved or whether it is in competition, if the current resource RBres is reserved if the node is the packet transmission source or if the node has already correctly decoded the packet, transmitting the packet of the stream associated with the resource, if not, attempting to decode the packet of the stream and, if the decoding is correct, storing the decoded packet in memory, if the current resource RBcomp is in competition, applying a method for managing stream collisions on the resources where n>1.

Abstract: Apparatus for spraying a fluid, including a pipe, a scraper capable of moving in the pipe, and a casing defining a storage volume for accommodating the scraper in a position for storing the scraper, the scraper being configured to push fluid in front of it which is present in the pipe when the scraper moves in the pipe, the storage volume being in fluid communication with the pipe and being configured to allow the scraper to move between the storage volume and the pipe. The scraper includes a first magnet, and the casing includes a second magnet capable of exerting a first force on the first magnet to move the scraper from the storage volume to the pipe.

Abstract: A valve including a body having an inner central orifice and a chamber, a piston formed by a rod and by a head mounted in the chamber, the rod extending outside the body and moving in a bore of an application system. The valve includes a first sealing device around the rod on one side of the valve where the rod extends outside the body, part of the chamber being filled with a pressurized control fluid to obtain movement of the piston against the force of a spring housed in the body. The valve includes a second sealing device around the rod, between the first sealing device and the chamber. The valve includes a vent duct in the rod that communicates with the inner central orifice between the first and second sealing devices and emerges in the open air or in part of the chamber communicating with the open air.

Abstract: Valve for a system for applying a covering product, including projecting or recessed shapes on a peripheral part, configured to cooperate with projecting or recessed shapes of a dedicated mounting and dismounting tool, these projecting or recessed shapes of the valve being configured to transmit a rotational movement to the valve, and to be secured to the tool. The projecting or hollow shapes of the valve include a first peripheral profile having at least one planar surface, and a second peripheral profile located behind the first profile relative to an outer end of the valve. The second profile has at least one first planar surface aligned with the planar surface of the first profile, and at least one second planar surface angularly offset relative to the planar surface of the first profile, such that the second planar surface of the second profile forms a shoulder relative to the first profile.

Abstract: An installation including an atomizer configured to atomize a fluid, a robot and a first station, the robot being configured to move the atomizer in a predetermined reference frame between at least a first position and a second position, the atomizer being configured to atomize the fluid when the atomizer is in the first position, a distance being defined between the atomizer and the first station, the distance when the atomizer is in the second position being strictly less than the distance when the atomizer is in the first position. The first station includes at least one sensor configured to measure at least one value of a parameter of the atomizer when the atomizer is in the second position.

Abstract: An electrostatic rotary sprayer for coating product including a spraying cup, a body and a drive turbine assembled in the body and configured to rotate the spraying cup about an axis of rotation defined by the body. The sprayer also includes electrodes for charging the coating product sprayed by the spraying cup, these electrodes being assembled on a ring attached on the body, and a skirt for discharging air around the cup. An annular slit, supplied by a pressurized air flow circuit with pressurized air, is defined radially between the ring and the skirt, with its outlet oriented toward the front of the sprayer.

Abstract: An electrostatic rotary sprayer for a coating product, including a spraying cup, a body, a drive turbine assembled in the body and configured to rotate the spraying cup about an axis of rotation defined by the body. The sprayer also includes electrodes for charging the coating product sprayed by the spraying cup, these electrodes being assembled on a ring attached on the body and each supplied with high voltage through a resistance. Each resistance extends axially outside the ring and is equipped, at its end opposite the electrode that it supplies, with a first electrical connection plug on a second plug of corresponding geometry provided on the body, with a movement parallel to the axis of rotation, and in that the ring is configured to be assembled and connected on the body, or disassembled and disconnected from the body while being equipped with electrodes and resistances.

Abstract: The present invention relates to compositions based on olefinic copolymers and/or polyacrylates in the form of stable and concentrated emulsions. Such compositions are particularly effective as additives for lowering the pour point of crude oils and/or for inhibiting paraffin deposition in crude oils, especially in one-pot form.

Abstract: An assembly device without visible screws for assembly of two parallel wooden slats comprises an intercalated fixing element engaged in two positioning grooves arranged side by side in the side faces. The fixing element comprises a metal slide having: a base part equipped with an oblong aperture extending longitudinally in the central part for the screw to pass through, two securing wings oriented in opposite directions from one another and designed to press in the grooves when the screw is tightened, and a screw head whose external dimension is greater than the visible second gap which is arranged above the grooves between the upper edges of the two wooden slats.
