Abstract: The invention relates to a pretreatment process for a brazing composition that comprises metallic particles with a granulometry in the order of the micrometer or nanometer, one or several binders and one or several solvents, said process comprising: a desolvation step of the brazing composition, so as to obtain a desolvated brazing composition, then a compacting step of the desolvated brazing composition so as to obtain a preform of metallic particles, said preform being able to be used for the sintering of an electronic, photonic, thermal or mechanical component onto a substrate, the brazing composition being represented either by a brazing paste, or by a suspension of metallic or metallic oxalate grains in suspension in a solvent.

Abstract: A method for controlling takeoffs of mechanical energy and/or air on a turbine engine for the propulsion of an aircraft. It is based on a protocol for the exchange of a request/authorization between and by the energy manager and a system for controlling the turbine engine. This protocol is implemented as a result of a modification of the takeoff requirement. It is intended to check whether the surge margin is compatible with the modification of the takeoff requirement and, if the need arises, to apply temporary measures in order to prevent surge in the turbine engine, for example by providing at least a part of the energy requirements by a buffer. This permits the optimization of the operation of a turbine engine for the propulsion of an aircraft, while avoiding the risk of surge of the turbine engine.

Abstract: The invention concerns a lid (2) comprising a skirt (3) for covering the opening of a can (1), in particular a paint can. The invention is characterized in that the skirt (3) comprises a peripheral edge (30), at least one stud (71) formed in the edge (30) and elastically coupled to said edge (30), at least one lock (72) mounted sliding on said edge such that said lock may take up a locking position wherein said lock is adapted to retain said stud in a position for engaging the lid on the can.

Abstract: The invention concerns a floating aquatic platform structure including a transparent base, capable of accommodating pieces of furniture and people, and the means to keep it upright within an area of natural or man-made water. The aquatic platform is designed in the form of a rigid set of self-supporting frames (1,17,18) in a geometrically simple shape, grouped together by base modules (2) with a limited number of frames, each frame (1,17,18) supporting a transparent slab (15) inserted into said frame and whereby the means for keeping the aquatic platform on the surface include floats (8,9,10) placed on at least two opposite sides of the platform.

Abstract: In a method and a unit for cleaning pieces contaminated with organic matter using a cleaning fluid, at least a part of the cleaning fluid circulates in a loop between a unit (1) for cleaning pieces, in which the cleaning fluid is charged with organic material on contacting the pieces and a processing unit in which living microorganisms biologically decompose the organic matter contained in the fluid leaving the cleaning unit (1). The method includes an at least partial sterilisation of at least a part of the cleaning fluid circulating in the installation, for limiting or preventing the presence of living microorganisms in the cleaning fluid serving the cleaning unit (1). The method and apparatus apply to the degreasing of pieces.

Abstract: An installation used to clean objects includes: a closed loop washing circuit (5A, 5B, 5C, 5D), a rinsing circuit (7A, 5B, 5C, 5D), a single pump (8) and at least one routine operating mode.
