  • Patent number: 8967417
    Abstract: A sealing system for an outlet of a plastic-lined cylinder has a plastic liner outlet extending into a bore of a boss. An insert is engageable with the bore, forming a primary seal between the insert and portion of the liner outlet. Further, a tapered compression surface of the insert engages a tapered bore portion of the liner outlet adjacent the primary seal for compressing the liner outlet and closing any annular assembly clearance at the primary seal for obviating opportunity for seal extrusion under pressure. An axial position in the boss, and dimensional integrity, of the liner outlet is maintained by engaging an annular distal end of the liner outlet in the bore by a stop. The stop can be integral with the boss. Reverse extrusion of the primary seal due to trapped gas and rapid decompression of the cylinder can be defeated by providing a leak path.

  • Patent number: 8365938
    Abstract: A gas-tight detonation-proof container for the transport and storage of detonation-dangerous material that can be opened and closed by remote control is provided. The container, which is of the type that can be opened by separation, will also, if required, be able to be used for the active detonation of dangerous material inside the same. The detonation-proof transport container according to the invention is particularly characterized in that it is opened and closed by a locking ring disposed between the two parts of the container and is arranged such that it can be circumrotated in the parting plane. In the closed state, the locking rings holds together the two parts of the container and, for this purpose, has a double-sided multi-toothed bayonet coupling which, upon a limited circumrotation, locks in the two parts of the container.
