Abstract: The present disclosure generally relates to containers and container end closures, and more specifically metallic end closures for small diameter metallic beverage containers. The present disclosure also relates to the tooling used to form the novel end closure, where the tooling is itself novel. The change of the angles on the die core ring improve the mobility of the metal while forming the end closure. Specifically, when manufacturing the new end closure with the new tooling, the press output is increased by over five times.

Abstract: An aircraft system for an aircraft is disclosed having a controller that is configured to receive at least one signal during a landing procedure of the aircraft and to determine that the aircraft is at a predetermined stage in the landing procedure, on the basis of the at least one signal. The predetermined stage in the landing procedure is before a command to extend at least one landing gear of the aircraft is issued during the landing procedure. The controller is configured to cause initiation of at least a part of a procedure to interrogate an aircraft braking system, on the basis of the determination.

Abstract: A method of printing and of authenticating a marking, having a visible printed anti-copy pattern produced by pseudorandom noise that is generated on the basis of a secret generation key, includes processing at least one image of the printed anti-copy pattern. The anti-copy pattern is printed onto a marking substrate using predetermined printing conditions. The phase of marking control involves: regenerating the pseudorandom noise on the basis of the secret generation key; creating, computationally, a digital file of an image of a simulated printed anti-copy pattern which corresponding to a projected printing quality of the regenerated pseudorandom noise; capturing at least one image of the printed anti-copy pattern; and comparing the captured image of the printed anti-copy pattern with the image of the simulated anti-copy pattern in order to determine, computationally, a mathematical distance between the image of the printed anti-copy pattern and the image of the simulated anti-copy pattern.

Abstract: A device for guiding an element in an orifice in a wall of a turbomachine combustion chamber is disclosed. The device includes a coaxial ring and bushing mounted one inside the other. The bushing includes two coaxial annular parts that are fastened to each other by welding and that define a groove for guiding a rim of the ring. Welding zones between the parts of the bushing are situated away from the path of the rim of the ring when moved along a privileged transverse direction of ring movement relative to the bushing when the combustion chamber is in operation.

Abstract: A turbomachine combustion chamber has primary and dilution air inlet orifices formed by die stamping to have edges that project into the inside of the combustion chamber, and stress relaxation and/or reduction means in the edges or in the vicinity of the edges of said orifices, said means comprising, for each orifice, one, two, or three slots formed in the edge or around a fraction of the edge of said orifice.

Abstract: A turbine engine annular combustion chamber includes inner and outer longitudinal walls connected upstream by a transverse chamber bottom and including a single-piece cowling covering the chamber bottom. Each of the longitudinal walls is inserted between corresponding flanges of the chamber bottom and of the cowling. The longitudinal walls, the chamber bottom and the cowling are assembled together by a plurality of first fixings between the longitudinal walls and the chamber bottom alternating with a plurality of second fixings distinct from the first fixings between the longitudinal walls and the cowling.

Abstract: A turbine engine annular combustion chamber, including longitudinal walls connected by a transverse chamber bottom and a single-piece cowling, the chamber bottom and the cowling each including an inner flange and an outer flange each with a plurality of holes made in it for the passage of fixing systems for fixing the cowling on the chamber bottom. Each fixing system has associated with it at least one tangential slot formed on the corresponding flange of the chamber bottom and/or on the corresponding flange of the cowling, each slot being formed in the immediate vicinity of the corresponding fixing system.
