Abstract: In a locking device for the fixation of a lid (1) on an opening (8) of a pressure container with at least two locking segments (5) displaceable at right angles to the axis of the opening 98), which segments (5) bear protrusions (6) and groove-like recesses along their circumference, which in the locked position cooperate with recesses (7) and protrusions along the brim of the opening (8), the displacement actuator (4) of the segments (5) is linked to the segments (5) and to at least one point of application that is on the lid (1) or on a member (3) connected to the lid (1). The segments (5) are arranged in the direction of the circumference of the lid (1) and are pivotably supported on the lid (1) by a swivel arm (16), separate from the displacement actuator (4), being interposed.

Abstract: In a method for extracting ingredients, particularly foreign substances, from liquids or solids dispersions by using compressed extraction agents such as, for instance, supercritical or liquid carbon dioxide, the liquid or dispersion is applied as a thin film in a pressure-tight reactor and the surface of the thin film is treated with the extraction agent, particularly carbon dioxide, wherein the surface of the thin film is constantly renewed over at least a portion of the layer thickness of the thin film by mechanically acting on said liquid or dispersion.
