Abstract: The invention relates to a pressing system, including a press having a first pressing tool and a second pressing tool. The first pressing tool and the second pressing tool being movable relative to one another to form a working space. A workpiece, a pressure generating device for generating a pressure curve acting on the workpiece in the working space, a temperature generating device for generating a temperature curve acting on the workpiece in the working space the workpiece running through an elongation curve (DVW) depending on the pressure curve acting in the working space and on the temperature curve acting in the working space. The first pressing tool and the second pressing tool running through a respective elongation curve (DVP1, DVP2) depending on the pressure curve acting in the working space and on the temperature curve acting in the working space, wherein the first pressing tool and/or the second pressing tool are designed such that their elongation curve (DVP1, DVP2) deviates by no more than 3.

Abstract: In connection with an electrode holder for immersion-type flow-type and attachment-type measuring systems in analytical chemistry, in particular for pH, conductivity, oxygen and chloride measurements, or the like, comprising an outer pipe in which an inner pipe carrying the measuring probe is supported in axially sliding relationship, and a stopcock blocking the supply of measuring agent by means of a plug of the stopcock when the inner pipe is retracted from the measuring agent it is proposed to leave the plug open on one side in the area of its passage channel and to have a remaining rear wall of the passage channel facing the supply opening of the measuring agent.

Abstract: A multiple combination electrode with associated multi-point plug mount, wherein the three measuring systems provided are arranged in a single electrode shaft provided on its one end with the measuring plane and carrying on its other end a plug-mount part forming, together with an associated matching plug-mount part fixing the connection cable, a triple plug unit with concentrically arranged plug contacts.
