Abstract: The invention relates to a method for measuring a tool received in a workpiece processing machine, the method having the following steps: providing a contact or noncontact tool sensing device for detecting positional data on the tool and for outputting signals representative of the positional data; providing an evaluation device for receiving and processing the signals and for outputting a tool geometry determined from the processed signals; detecting a sequence of a first number of positional data on the tool and outputting signals representative of said positional data to the evaluation device; processing the signals representative of the first number of positional data in order to obtain a first approximation of the tool geometry; comparing the first number of positional data to said first approximation of the tool geometry and excluding a subset of the first number of positional data depending on a predetermined criterion, in order to obtain a second number of positional data; processing the second number

Abstract: A network for monitoring bodily functions of a patient is disclosed. The network comprises at least two distinct network nodes that can be connected to a body of the patient. At least two of the network nodes can have at least one medical function, such as, for example, a diagnostic function and/or a medication function. The network nodes can communicate directly with one another via the body of the patient and can interchange data and/or commands.

Abstract: The invention relates to a graphite electrode with an electrical connecting element as well as to a furnace for graphitizing carbon-containing materials by means of such graphite electrodes. According to the invention, it was found that the drawbacks known from the prior art are eliminated by establishing an electrical connection between the graphite electrode and the connecting element by means of wedge-shaped contacting elements. The contact pressure between the contact element and the wedge-shaped surface on the graphite electrode required for electrical conductivity of the interface can be influenced by means of the wedge angle and the contact surface.

Abstract: To determine the position of rotationally drivable tools in machine tools, the moment of separation of the tool to be measured and a measuring beam, for example a laser beam of a light barrier, is used. The tool to be measured is first positioned in such a manner that the measuring beam is interrupted, and is then moved to a measuring position in which the moment of separation of the tool and the measuring beam occurs, and the measuring beam is no longer interrupted by the tool during at least one complete revolution. The moment of separation is used to determine the position of the tool.

Abstract: Wastewater containing impurities refractory to secondary treatment is first introducted into an aerobic biological treatment stage operating with an oxygen-enriched stream and subsequently into a precipitation stage where the biologically treated wastewater is combined with Ca(OH).sub.2 to precipitate Ca(OH).sub.2 CaCO.sub.3 sludge which adsorbs or occludes impurities. The clear liquid, separated from the resultant sludge, is passed to a second precipitation stage where it reacts with a CO.sub.2 and oxygen-containing waste gas at least in part from the aerobic biological treatment stage, thereby forming additional CaCO.sub.3. Waste gas withdrawn from the second precipitation stage, being enriched in oxygen is recycled to the aerobic biological treatment stage.
