Abstract: A can or container reformed from an existing open ended can adds additional volume and integral thread portions to form a recloseable can. An existing can is inverted, drawn to increase the volume, an end wall pierced and reformed into an outwardly curled lip, thread portions formed along a perimeter portion of the can body adjacent a first end, and a new end seamed to the original open, second end of the can. A cap with thread lugs cooperates with the thread portions on the external perimeter of the reformed can to originally and subsequently reseal the can once the can has been opened.

Abstract: During implementing a composite metal part by compaction of an insert having reinforcing fibers in a metal body or container, gas used for compaction may enter the cavity formed in the container for receiving the insert between a lid covering the insert and the container, which can prevent or degrade compaction and diffusion welding of fiber sheaths of the insert therebetween and/or with walls of the cavity. To solve this problem, the present method includes initiating isostatic compaction by a phase including raising and maintaining temperature, followed by a phase including hot-feeding pressurized gas, and machining an assembly to obtain the part. The temperature raising phase includes a diffusion pre-welding of material rigidly connecting the pressure-adjusted walls of the lid and the container. The method can be used for designing parts having a tensile and compression resistance, such as parts for aircraft landing gear.
