Abstract: A fluid system for a pump circuit (10), in particular a hydraulic high-pressure pump circuit, has a function block (12). In the housing of the function block, fluid-conducting paths extend and are connected to valve components (32, 46) at least partially. A filter device is an at least partially integrated constituent part of the function block of the fluid system. The filter device (46) with its filter housing (56) can be connected to the function block (12) such that at least one filter element (70) is received in the installation space (72) of the function block.

Abstract: The invention relates to a process control system comprising a calculating unit enabling a charge value (W) to be determined from operations occurring in the process control system. Preferably, said process control system comprises a process control computer with a web server and a computer which is used to access the processes control computer via Internet. The charging value (W) is especially a service fee which is to be paid to an application service provider by a user of the process control system.

Abstract: The invention relates to an adsorber element and to a method for the production thereof, comprising a carrier material (1) on which adsorbent particles (3) are arranged as the adsorber layer using a binding agent (2). According to the invention, the adsorber layer comprises inorganic fibers (4) and the binding agent (2) is designed as a colloid.

Abstract: A method is disclosed for a system including at least one process management computer and a number of field devices, whereby status and control signals are transmitted between at least some of the field devices and the process management computer using a TCP/IP protocol over a communication channel, preferably a radio connection and/or the Internet. A process management system includes a process management computer with a web-server, a client computer with an Internet browser and a number of sensors and actuators. The process management system may preferably be operated by way of the Internet, using the client computer.

The filter device is an at least partially integrated constituent part of the function block of the fluid system as a result of the fact that a filter device (46) with its filter housing (56) can be connected to the function block (12) in such a way that at least one filter element (70) is received in the installation space (72) of the function block.

Abstract: The invention relates to a humidity- and/or heat-exchange device, for example a plate heat exchanger a sorption rotor, an adsorption dehumidifying rotor or the similar, provided with humidity- and/or heat exchange surfaces which make it possible to introduce humidity and/or heat into a fluid flow and/or to remove them therefrom and/or to exchange said humidity and/or heat between fluid flows. The inventive device is also provided with a coating, which makes it possible to cover said humidity and heat exchange surfaces and consists of a zeolithe material and a bonding agent. In order to improve the performance of the humidity- and/or heat-exchange device, the zeolithe material is embodied in the form of a synthetic nano-zeolithe consisting of particles whose size is <1000 nm.
