Abstract: An apparatus and a method for automated semantic annotation of a process model having model elements named by natural language expressions, wherein said apparatus comprises at least one semantic pattern analyser which analyses the textual structure of each natural language expression on the basis of predefined semantic pattern descriptions to establish a semantic linkage between each model element to classes and instances of a reference process ontology for generating a semantically annotated process model.

Abstract: The invention relates to an isolating switch system. The isolating switch system includes an isolating switch for interrupting a main line running between an electric power source and an electric consumer. The isolation switch is controlled in dependence on an ignition switch. The isolating switch system includes a signal generating unit, a signal detector unit and a signal processing unit. The signal generating device generates an electric signal that can be fed to the electric consumer and conducted to the ignition switch. The electric signal, in dependence on a switching state of the ignition switch can be conducted to the signal detector unit via a conduction path. The signal processing unit, upon detection of the electric signal, causes the isolation switching system to open or close the main circuit line. The electric signal generated by the signal generating unit is a pulsed signal.

Abstract: The invention relates to a hydraulic accumulator, particularly in the form of a suction stream stabilizer, having an accumulator housing (10) which is provided with two fluid connections (16) between which a deflection device (22) is arranged which has an adjoining housing part (26) which accommodates a separating element which separates the interior (18) of the accumulator housing (10) from an accumulator volume (30). Solutions for long-term and functionally reliable operation can be achieved on account of the separating element being formed from a piston (28) or a bellows (50).

Abstract: A piston-type accumulator includes an accumulator housing provided in the form of a cylinder tube (1). A separating piston (15) separates two working spaces (5) and (6) from one another in the housing and can be displaced in an axial direction within a piston stroke area (19) of the cylinder tube (1). The cylindrical tube is closed at one axial end by a closure part (7). The closure part is defined by deforming a deforming area (9) of the wall of the cylinder tube (1). The deforming area adjoining the piston stroke area (19) is provided in the form of part that exists as a single piece with the housing. A stop body (25), which limits the movement of the separating piston (15) before reaching the deforming area (9), is provided inside the cylinder tube (1) at the location where the piston stroke area (19) transitions into the deforming area (9).

Abstract: A device for damping pressure surges in a fluid with a housing (10) and a piston (14) that can be longitudinally displaced inside the housing (10) against the pretensioning force of a spring energy store (12). The piston (14) interacts with another piston (24), which is guided in a connecting piece (26) of the housing (10) in a manner that enables it to be longitudinally displaced. During the operation of the device, the piston (14) exerts a pressure force onto the other piston (24) when the other piston is in any displacement position. Even pressure surges occurring with a high frequency can be reliably controlled in a functionally reliable manner.
