Abstract: The invention describes a method of positioning a welding torch (10) and a welding wire (13) at the center of a seam (32). The welding torch (10) is positioned by means of a robot arm on a predetermined or programmed position between two seam edges (34, 35), after which an alignment process is run whereby the robot arm moves the welding torch (10) in one direction until a short circuit occurs between the welding torch (10) or the welding wire (13) and a seam edge (34, 35) of the workpiece (16), and the welding torch (10) is then displaced in the opposite direction by the robot arm until another short circuit occurs between the welding torch (10) or the welding wire (13) and another side seam edge (34, 35) of the workpiece (16). A control system (4) then evaluates the displacement path in order to calculate a seam center, on which the welding torch (10) is positioned. No additional hardware components are needed in order to implement the method.

Abstract: A method and a fire-alarm system controls stationary fire-extinguishing systems. The fire-alarm devices of the fire-alarm system are equipped with one or more detectors. If at least one pre-adjustable alarm threshold of a fire identification characteristic is reached, the fire-extinguishing device is activated and the fire detectors are selectively switched to a higher stage of sensitivity. The detectors to be switched are locally selected depending on the actual development of the fire in terms of space. The dynamic adaptation of the sensitivity of the detectors to the development of a fire permits analyzing the development of the fire through the generated smoke, water vapor or extinguishing-water mist, and to influence the fire-extinction process in a targeted manner.

In order to provide simple constructional conditions it is proposed that the two eccentric shafts (2, 3) are provided with a different angular position (&phgr;) and that the connecting rods (4) of the two eccentric shafts (2, 3) extend in an inclined manner with respect to each other.

Abstract: A method for the finishing treatment of work pieces, uses a processing device including a tool spindle for a processing tool and a numerically controlled (NC) feeding device. The force of the contact pressure applied to the work piece on the side of the work piece is measured and the measured force values are supplied to the numerical control (NC), which determines and fixes the feed rate at which the processing tool is advanced against the work piece. The finishing treatment is carried out in a force-controlled operating mode, in which the feed rate is controlled depending on the force of the contact pressure acting on the processing tool. A processing device is employed whose tool spindle is movably supported in the direction of the feeding movement on leaf springs on the feeding device. The processing device includes a force-measuring device effective between the tool spindle and the feeding device and operating substantially free of deformation.
