摘要:
A turbomachine exhaust casing with connection roots between the structural arms of the casing and the annular endplates of the hub of the casing, each of said the roots having a profile that is optimized so as to reduce the level of stress in the connection portions, and thus increase the lifetime of the exhaust casing.
摘要:
A system for dispensing a strip of absorbent product in the form of a roll, of the type comprising a roll, formed of a wound strip of absorbent product, axially delimited by a first lateral side and a second lateral side, a dispenser for dispensing the absorbent product in the form of a roll, of the type comprising a frame and a cover which is mounted such that it can move, means for holding and guiding the rotation of the roll with respect to the frame, which means comprise a first holding element for holding the roll and which is borne by the frame, and a second guiding and positioning element which is borne by the cover such that it is fixed in terms of rotation and which can be housed axially in a lateral housing of the roll, characterized in that the second guiding and positioning element comprises at least one projecting portion on which an internal wall of the second housing is able to slide for guiding the rotation of the roll if the roll is a complementary roll, and which is able to dig into the strip of product of which the roll is formed if the roll is not a complementary roll so as to prevent it from rotating.

摘要:
The invention relates to a dispenser of rolls placed side by side, each held in rotation about a horizontal spindle (1), comprising a casing (10) surrounding the rolls, a cover (14) that complements the casing, at least one opening (2) in the lower part of the dispenser, and a sliding access panel (3) intended to partially close off the said opening so as to allow access to one of the rolls known as the roll in use, and at the same time, prevent access to the other roll known as the spare roll contained in the dispenser. According to the invention, the dispenser further comprises a mechanism intended to immobilize the access panel (3) under the spare roll and release it automatically and only when the roll in use is empty.

The invention relates to a dip comprising an acid aqueous solution having no ammonium ion, fluoroborate ions or citrate ion and containing per liter: between 10 and 60 g of Zn2+ ions and between 20 and 100 g of Mn2+ ions. The invention is characterised in that it comprises a buffer agent that maintains the pH at a value of between 3 and 7, preferably between 4.5 and 6 or better still between 4.8 and 5.5, and another agent, different from the buffer agent, which is used to bring together the deposition potentials of couple Zn/Zn2+ and couple Mn/Mn2+. The inventive dip used to deposit a Zn and Mn alloy by electrolysis.
摘要:
The invention concerns a double flow turbo-jet engine, including a re-heating channel of the primary flow and an ejection nozzle, the secondary flow emerging at least partially in the primary flow upstream of the re-heating channel, the re-heating channel including a burner ring, including a flame holder gutter in the form of a ring portion whereof the upstream section is situated in the secondary flow, receiving a fuel manihold and a protective tubular screen of the manihold. The invention is characterised in that the gutter includes an upstream recess linked with the secondary flow, and the screen includes, on its upstream section, at least one ventilation orifice of the space situated between the screen and the manihold.
