摘要： A convex type bottom with a bearing rim for bottles for industrial gases, obtained by hotforging a steel billet, has the lower outer surface consisting of a central circular flat area (2), a first frustoconical annular area adjacent the central area (2), inclined upwards, a second frustoconical annular area adjacent the first frustoconical annular area, inclined downwards, and a subvertical frustoconical area (6) radiused, on the one side, to the second frustoconical annular area and, on the other side, to the flat surface (7) of the bearing rim (8). Provided on the inclined frustoconical annular areas are corrugations (3, 4, 5).
Such a configuration of the bottom permits the defects to be eliminated due to creeping of the material during forging.-

摘要： The present invention relates to a reinforcement device for the tubular shell of an artillery projectile of the type intended to carry a useful load. The portion of the tubular shell to be reinforced is that comprised between the driving band and the base plug of the projectile. The reinforcement device according to the invention consists of a metal structure (5) having a cylindrical side surface with an outer diameter substantially equal to the inner diameter of the portion of the tubular shell (4) to be reinforced. This metal structure (5) can have several embodiments depending on the useful load contained In the projectile.
