Abstract: The invention relates to a fuel burner (2) that is to be integrated into a furnace (3) or a boiler and is arranged in said furnace (3) or said boiler in a target position, the burner (2) comprising means (C1-C9) for measuring an offset relative to the target position.

Abstract: A burner designed to be fitted in a combustion chamber, the burner including: a central nozzle configured to have an oxidizer and fuel supply; several peripheral nozzles configured to have an oxidizer and fuel supply and which each have at least one upstream fuel injector in order to pre-mix the fuel and the oxidizer in the nozzle; at least one oxidizer input connected to the said central and/or peripheral nozzles; wherein peripheral nozzles each have a flame stabilizer located at the end of the peripheral nozzle designed to exit into the combustion chamber, as well as a tip injector to inject fuel at the end of the peripheral nozzle.

Abstract: A premix burner made up of an air inlet tube of length L and a single specific gas injection, the gas injection includes an upstream gas injector, a mixer, a downstream gas injection situated at a distance L3 from an upstream end of the air inlet tube and a stabilizing element, where the gas injection constitutes a one-piece mechanical assembly that ensures a self-stable elementary flame.

Abstract: A cardio-pulmonary compression board includes a board (10) configured for a patient. A leg (20) is pivotally connected to the board, and the leg includes a free end portion having a mechanical feature (35) configured to be received in a compression device to adjustably secure the compression device at a distance from the board in an operational position. A locking mechanism (32, 42) is configured to releasably maintain the leg in the operational position, which is transverse to a plane of the board.

Abstract: A burner module in an air stream has a feed pipe of substantially circular cross section and an axis, fuel injection orifices situated on the pipe and intended to produce a flame, oxidant injection orifices and fins arranged symmetrically with respect to a plane P of flow of the fuel upstream of the burner module and laterally on the pipe on each side of the fuel injection orifices. There are at least two fuel injection orifices in a section of the pipe and they have an axis that makes an angle ? with the plane of flow P of the oxidant. In this way, gas is injected at several orifices situated in at least two divergent planes. These two planes delimit a space to which fuel and to which oxidant are not supplied.
