Abstract:
Pressure of a gas in a gas accumulator coupled to a fluid circuit is measured in a system involving separating gas from pressure fluid in a gas accumulator by a separating element, measuring pressure of the pressure fluid with a pressure detector coupled to the gas accumulator when the separating element is in a preadjustable position having a gas pressure assignable to it, detecting the preadjustable position by a monitor coupled to the pressure detector, and initiating measurement of the fluid pressure upon detection of the separating element in the preadjustable position.
Abstract:
A hydraulic accumulator has a dividing wall located in a housing and separating the housing into a liquid chamber and a gas chamber. The dividing wall is held by a retaining part connected to a connecting part. The retaining part at least partly surrounds the connecting part for producing the connection.
Abstract:
A pressure store includes a housing (2) having a first sub-chamber (8) arranged between the housing (2) and a flexible separating diaphragm (40), a second sub-chamber (54) arranged between the separating diaphragm (40) and a supporting body (48), and a third sub-chamber (28) encompassed by the supporting body (48). The first sub-chamber (8) can be filled with a first fluid. The second sub-chamber (54) and the third sub-chamber (28) are connected to one another in fluid-conducting fashion and can be filled with a second fluid. The first and the second sub-chambers (8, 54) vary in respective sizes as a result of movements of the separating diaphragm (40) as a function of the respective filling state. The first fluid is a storage medium and the second fluid is working medium. The second sub-chamber (54) is increased in size during the extraction of storage medium from the pressure store and is reduced in size during the filling of the pressure store with storage medium.
Abstract:
The present invention relates to an optical bandpass filter system that has at least one combination of a bandpass filter that provides a first nanostructured metallic layer (4) and a bandstop filter comprising a second nanostructured metallic layer (7), which are arranged one behind the other, and the layer thicknesses of which are different. The bandstop filter is tuned to the bandpass filter in such a way that it blocks a contiguous wavelength range that partially overlaps a pass-band width of the bandpass filter. With the suggested optical filter system it is possible to create various filter characteristics side by side in a small space with a small pass-band width.
Abstract:
The invention relates to a hydropneumatic piston/cylinder arrangement, in particular for use as a spring element and/or shock absorber element, comprising a cylinder (1) and a piston (15) which is axially movable in the cylinder chamber (5) of said cylinder, the cylinder chamber being tilled with hydraulic fluid. The piston (15) is connected to a piston rod (13) which extends outwards in a sealed manner from one end of the cylinder (1), and the base of said piston, which is remote from the piston rod (13), can he operatively connected to a pneumatic spring mechanism (7) in order to convey fluid. Said piston/cylinder arrangement is characterised in that a piston accumulator (7), the accumulator piston (19) of which directly adjoins the hydraulic fluid situated in the cylinder chamber (5), is provided as the spring mechanism.

Abstract:
A method and an apparatus for automatic extraction of process model comprising model elements named by natural language expressions and annotated with semantic linkages to a reference process ontology are disclosed. The process model is split into partial process models by which an annotated partial process model is created. Process goals are decoupled from each annotated partial and hierarchical process goal tree is generated for each annotated partial process model.
Abstract:
A device for the pulsed release of an amount (3) of fluid that is stored in a storage housing (2), in particular for implementing a start-stop function in automatic transmissions, with a piston (5) that is supported against a first energy storage device (4) and that, with the capacity to move within the storage housing (2), limits in conjunction with the latter the amount (3) of fluid that can be held and that, when triggered by an actuation means (6) and released by a locking means (7), pushes the amount (3) of fluid out of the storage housing (2) in a pulsed manner, the locking means (7) having individual catch means (8) that in the locked position keep the piston (5) in its pretensioned position, and that, when actuated by the actuation means (6), release the piston (5) in a release position, is characterized in that in any travel position of the piston (5), the catch means (8) are at least partially in contact with the inside wall of the piston (5) facing them, and that for locking of the piston (5), the catch means (8) act in that end region (9) of the piston (5) that is located adjacent to the stored amount (3) of fluid.
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.
