    Abstract: A visco-type seal is disclosed wherein a sealing pressure is built up in a fluid by means of one or more helical windings, the fluid being enclosed in a narrow clearance between a stator and a rotor. The alignment of the rotor within the stator is insured by providing a thin layer of material at the outer ends of at least one of the helical windings so that the clearance in a radial direction between the stator and the rotor at this location is less than the clearance existing in a radial direction between the helical windings and the stator. In one embodiment, the stator is designed as a sleeve which has a flexible connection in the radial direction with respect to a wall. The stator or a sealing element fastened thereto is movable in an axial direction by means of a resilient force to obtain a proper sealing when the device is at rest.

    Abstract: A closure assembly for a pressure vessel having at least one open end in which a plurality of girder assemblies extends across the open end, with each of the girder assemblies consisting of a plurality of girders which are connected together. Each girder assembly is individually releasably connected to the vessel.

    Abstract: An apparatus forming a closure seal especially adapted for utilization wherein high internal pressures are to be contained within a cylindrical high pressure cell. The closure seal is formed of a concave inner cylinder which readily transforms the pressures exerted within the cell to lateral forces which are exerted between the concave closure seal and the cylinder walls of the cell.

    Abstract translation: 一种形成封闭密封件的装置，特别适于利用，其中高的内部压力将被包含在圆柱形高压电池内。 闭合密封件由凹入的内筒形成，其容易地将施加在单元内的压力转换成施加在凹形封闭密封件和单元的圆筒壁之间的横向力。
