Abstract: The present invention relates to a device for displaying current status during order processing in a production plant, with an inter-face (1) to a data processing system (5), from which up-to-date in-formation is obtained about order processing in the production plant, a processing unit (2) for processing the up-to-date information from the data processing system (5) relating to at least one process selected by an operator in graphic form, whereby processing in graphic form includes the graphic display of the allocation of material supply areas for the source process, the allocation of production areas for the make process and essential information for packaging and delivery for the deliver process, and an output unit (3) to output up-to-date information relating to the selected process in the graphic display on one or a plurality of monitors (4). The present device allows employees to have a fast and clear overview of the current status of order processing without additional training.

Abstract: The invention relates to a device and method for creating, providing and documenting assembly and test instructions comprising the following components; an acquisition device (1), an interactive electronic documentation device (5) connected thereto for processing the captured assembly and test instructions, to which device a telephone and address directory (6) and a document management system (7) for exchanging status messages, order-specific assembly and test documents, text modules, control files and order data are connected, a signature device (9) for verifying documents (8) created by the documentation device (5) and an archive system (11) which is connected to the signature device (9) and the document management system (7).

Abstract: A circuit arrangement includes a load sensing system (LS) with individual loads (10,14) arranged in series forming a series section, and in parallel forming a parallel section. A hydraulic supply circuit (12) includes a supply pump (P) and a runback (16) for fluid. The load sensing system (LS) determines the highest load pressure in the series section and the parallel section. The loads of the parallel section can be actuated independently from the pressure level of the loads of the series section due to the highest load pressure being transferred as a control pressure to a valve unit (18) such that, as long as the load pressure of the parallel section is higher than the load pressure of the series section, the valve unit restricts the runback (16) so that the pressure of the supply pump (P) matches or exceeds the pressure required in the parallel section. Sufficient fluid pressure for the load in the parallel section is ensured independently of the number of loads in the series section.

Abstract: The invention relates to a circuit arrangement comprising a load sensing system (LS) wherein individual loads (10,14) are arranged in series, forming a series section, and in parallel, forming a parallel section, in a hydraulic supply circuit (12) comprising at least one supply pump (P) and a runback (16) for fluid, the load sensing system (LS) determining the highest load pressure in both the series section and parallel section. The loads of the parallel section can be actuated independently from the pressure level of the loads of the series section due to the fact that the respectively highest load pressure is transferred as a control pressure to a valve unit (18) in such a way that, as long as the load pressure of the parallel section is higher than the load pressure of the series section, the valve unit restricts the runback (16) for fluid so much that the pressure of the supply pump (P) matches or exceeds the pressure required in the parallel section.

Abstract: A switching device for a machine, especially a digger, has at least one supply connection and one useful connection in addition to at least one hydraulic accumulator. An on-off valve is arranged between the supply connection and the useful connection, and separates the supply connection at least partially from the useful connection in one of its switching positions, in addition to ensuring that the hydraulic accumulator is charged on the fluid side via the supply connection. In another switching position, the supply connection is connected to the useful connection. A substantial improvement relative to conventional switching devices is attained by being able to guarantee an emergency function before the machine is used to perform work.

Abstract: A switching device controlling at least one hydraulically operating apparatus has two check valves working in opposition to one another in a feed conduit and a discharge conduit, respectively. The conduits are connected to the operating apparatus, as well as to a pilot valve. Two openable nonreturn valves are connected parallel to the two check valves. The control line of one openable nonreturn valve is connected to the blocking connection of the other openable nonreturn valve. The switching device is especially for controlling a hydraulic cylinder to provide a float setting at low cost, with reliable operation, and with few components.

Abstract: The invention relates to an accumulator charging valve, which for the connection of an inlet P supplying a hydraulic system 10 to an outlet T when an adjustable upper charging pressure in the hydraulic system 10 is reached and for separating this connection when an adjustable lower charging pressure in the hydraulic system 10 is reached, is provided with a control piston 42, which in one of its two switching positions breaks the connection between the inlet P and outlet T and in the other switching position makes this connection. By means of a separating device, a control connection B connecting the hydraulic system 10 to the accumulator charging valve can be separated from the outlet T. On reaching the adjustable upper charging pressure, by means of at least one sealing part of the separating device, the connection forming a leakage point between the control connection B and the outlet T can be sealed hermetically.
