    Abstract: A pressure vessel comprising a cylindrical stress liner, a pair of end plates, a plurality of annular shrink rings positioned about the circumference of the stress liner, and a plurality of coolant-filled annular cooling coils positioned about the shrink rings is disclosed. Nonuniform stress producing bending stresses in the shrink rings are eliminated by the method comprising the steps for detecting a stress concentration in a shrink ring and causing coolant to be recirculated from a reservoir through the coil about the shrink ring.

    Abstract: The invention relates to a process for rapidly letting-down the pressure in continuous high pressure polymerization systems for the polymerization of ethylene. In this process, the let-down hot reaction mixture is passed into an expansion vessel in such a way that the jet of let-down hot reaction mixture issuing from the let-down line is led into the partially water-filled expansion vessel at an angle of from 0.degree. to 45.degree. to the water surface, so that the jet does not enter below the surface but must touch or strike it. The method described makes it possible to let the mixture down partially and thus to slow down the decomposition in the case of explosive decomposition reactions occurring in the polymerization system.

    Abstract: What follows is a description of a unique arrangement forming safety equipment for installations containing a medium under pressure. The safety equipment includes a wall of the installation whose thickness is reduced in a predetermined region relative to the remaining region of the wall and an element disposed within the installation which extends over and beyond the reduced thickness region of the installation wall. The element is provided with bulges at its ends which define along with the inner surface of the installation wall a reduced flow cross section. This reduced flow cross section is chosen so that the pressure prevailing during normal operation in the space defined by the inner surface of the installation wall and that portion of the element between the bulges is the same as the pressure prevailing in the installation.

    Abstract: An improved rupture disc pressure relief arrangement for use with a high pressure vessel is described comprising a rupture disc having one surface thereof exposed to the internal high pressure of the vessel and means for establishing a variable pressure at a second surface of the disc. A disc which ruptures at a predetermined differential pressure can be employed over a relatively large range of operating pressures by varying the pressure at the second surface when changes in the operating pressure are made. The need for replacement of the rupture disc with changes in the operating pressure of the vessel is thereby avoided.

    Abstract: A housing has an outlet and can be mounted on a vessel so that the outlet communicates with the inlet opening of the vessel. The housing accommodates a reel on which a hose is mounted and the hose carries one or more hydrodynamic cleaning devices which can be lowered into and withdrawn out of the vessel by turning of the reel. A valve can close the outlet when the cleaning device is not to be used.
