Abstract: The mold wall forms the boundary of a cavity provided with a filling opening and is divided vertically into several segments, which are connected to each other in such a way that they can separate under the action of a force acting outward from the cavity. At least one pretensioned elastic element is installed outside the cavity, which is in effective contact with at least one segment, so that, because of the pretension, an elastic force acts on the segment in the direction toward the cavity. A tensioning element is provided to pretension the elastic element, this tensioning element being installed outside the mold wall to serve as an abutment for the elastic element, and that the elastic element be made of a creep-resistant material.

Abstract: In a method of moistening such articles as tools (drills, band saws, circular saws, thread cuttters and similar tools as well as stamping, drawing, and sectioning tools) or workpieces (metal or plastic articles being machined, pipes that are being sawn through, or sheet metal being rolled into structural piping for example) with a liquid (such as a lubricant or coolant for tools and workpieces or an adhesive for workpieces), wherein the liquid is removed from a reserve of liquid and supplied by way of a pipeline to a dispenser that is aimed at the area of the article to be moistened, the pipeline having flow controls and a blender for blending a gaseous medium into the liquid, the improvement wherein the liquid is mixed with the gaseous medium in a gyration chamber into a fluid that is supplied through tubing to a dispenser and sprayed onto the area to be moistened through the dispenser.
