Abstract: A method is for producing seals on faces of electrochemical reactor components intended to be stacked in order to form an electrochemical reactor Each component is in the form of a plate and having a first face and an opposing second face. The first face is designed to receive a first seal and the second face is designed to receive a second seal. The method includes shaping the first seals on the first faces of the components, the first seals being at least partially polymerized; depositing the second seals on the second face of the components; and shaping the second seals by compressing a stack formed from the components alternating with molding plates.

Abstract: The method of the invention relates to a method for welding a first (20) and a second (30) layers together. The second melting temperature of the second layer (30), Tm,2, is lower than the first melting temperature of the first layer (20), Tm,1. After having formed a layup (50) by placing the first layer (20) on top of the second layer (30), a rotating tool (70) is pressed and translated over at least a friction portion (15) of the upper surface (20u) of the first layer (20) such that the temperature reached by at least a portion of the upper surface (30u) of the second layer (30) is higher than the second melting temperature, Tm,2. Restraining means allow preventing molten second material from flowing out of the layup (50). Materials of first (20) and second (30) layers are chosen among the following materials: metals, semi-metals, or semiconductors.

Abstract: A stabilizer (1) includes a first passage (20-23) which connects a compressed gas source (2-3) to the circuit breaker and a second passage (9, 16, 34, 22) which makes the circuit breaker communicate with the atmosphere, these passages being normally closed, as well as means (10) for opening the first passage when the gas pressure in the circuit breaker is lower than a first value and means (31, 13) for opening the second passage when the gas pressure in the circuit breaker is higher than a second value. Application to high-tension air blast circuit breaker.
