Abstract: A battery including an autonomous protection device electrically connected in series between the plurality of electrochemical cells and one of the positive pole and the negative pole of the battery.

Abstract: A method for dry fluxing at least one metallic surface of an article comprising the steps of:a) passing at least one initial gas mixture comprising (1) at least one of an inert gas and a reducing gas and (2) an oxidizing gas mixture comprising water vapor into at least one apparatus for forming excited or unstable gas species, the initial gas mixture including 50 ppm to 6% water vapor;b) converting the at least one initial gas mixture to at least one primary gas mixture comprising excited or unstable gas species; andc) treating the surface to be fluxed, at a pressure close to atmospheric pressure, with a gaseous treatment atmosphere comprising excited or unstable gas species and substantially free of electrically charged species obtained from the primary gas mixture.

Abstract: A method for wave soldering a circuit having two or more faces comprising the steps of:(i) passing at least one initial gas mixture comprising at least one of an inert gas, a reducing gas and an oxidizing gas into at least one apparatus for forming excited or unstable gas species;(ii) converting the at least one initial gas mixture into at least one primary gas mixture comprising excited or unstable gas species and substantially free of electrically charged species;(iii) treating each of the two or more faces of the circuit with the at least one primary gas mixture at a pressure close to atmospheric pressure; and(iv) contacting the two or more faces of the circuit with at least one wave of a liquid soldering alloy.

Abstract: A device making it possible to carry out wettability measurements under a controlled atmosphere, comprising an apparatus (5) for measuring the wettability of at least one surface portion of a sample by a liquid metallic solder, at least partially included in an enclosure (6) which includes a gas injector which comprises at least one set of ducts (10) mounted in series and/or in parallel, at least one portion of which includes gas injection orifices, and is fed by at least one gas supply pipe connected to the set at a primary connection node, the dimensioning of the set respecting the following relationship:.SIGMA..omega..sub.i /.SIGMA..phi..sub.i .gtoreq.1 preferably.gtoreq.1.5;where .SIGMA..omega..sub.i represents the sum of the internal cross sections of the gas supply pipes which feed the set and .SIGMA..phi..sub.i represents the sum of the cross sections of the gas injection orifices of the set of ducts.
