Patent number: 5078797Abstract: A process for obtaining a plate of zirconium alloy comprising at least one portion of excess thickness of at least 0.5 mm relative to a large adjacent face, the portion having edges with angles equal to 90.degree. to 105.degree. and flanks which are connected without depressions to the large adjacent faces. According to the process, a surface portion of a blank plate located straight above a desired portion of excess thickness is coated with a continuous coating which is resistant to a pickling composition to be used, the coated portion widened beyond the desired portion of excess thickness by 0.5-1.5 times the amount of the excess thickness. The coated blank plate is immersed a plurality of times, without passage of electric current, in a pickling bath comprising HF, an oxidizing agent and water, and having a dissolved Zr content less than 12 g/l and a temperature below 35.degree. C. Each immersion removes less than 0.3 mm of thickness over the portions of the blank plate which are not coated.Type: GrantFiled: December 13, 1990Date of Patent: January 7, 1992Assignee: Compagnie Europeenne du Zirconium CezusInventor: Jean-Claude Bertrand

Patent number: 4549242Abstract: This invention concerns a multi-pole circuit breaker with molded case and static tripping unit, comprising an electronic device to process the signals delivered by current transformers associated with each pole, which electronic processing device is part of a subassembly inserted in a compartment of the molded case and delivers a tipping signal to a tripping coil in the case of an overload or a short-circuit. A feature of the circuit breaker according to the invention is that the aforementioned compartment is sealed off from the rest of the inside of the molded case and is in open communication with the ambient atmosphere by means of ventilation holes provided in the outer walls protected from the circuit-breaking gases generated inside the casing and is cooled down by the air circulating through these ventilation holes, while the aforementioned current transformers are housed in the other separate part of the casing.Type: GrantFiled: June 7, 1982Date of Patent: October 22, 1985Assignee: Merlin GerinInventors: Jean-Pierre Nebon, Pierre Barnel, Robert Denis, Claude Bertrand
