Abstract: The vessel comprises a part having an end portion which is introducible into a second vessel part and which has a cylindrical outside surface formed with an annular recess. The second vessel part has a connecting part having a cylindrical inside surface formed with a recess in the form of an annular groove and having a connecting duct which extends from the outside into the recess tangentially. When the two casing parts are in a connected position the two recesses bound a guide duct for a flexible closure part which is made, for example, of a steel string or cord or the like and which is introduced through the connecting duct into the guide duct to interconnect the two casing parts and withdrawn from the guide duct to release the two casing parts (1, 1a, 2a).

Abstract: This invention is concerned with an improved safety rupture disk assembly. This rupture disk assembly, which is designed for a fluid containment vessel, comprises two main parts: a removable rupture disk, and a cover plate. The rupture disk, of course, is designed to rupture, or fail, at a predetermined pressure, and to be easily removed and replaced by another rupture disk in the event of a failure. The cover plate is designed so as to "float" over the rupture disk and automatically seal the opening of the vessel after the pressure within the vessel has been release by disk failure. Additionally, nuts, washers and sealing wires are provided for positively securing the cover plate over the opening resulting from disk failure and for preventing inadvertent securing of the cover plate.
