Abstract: A computer-implemented method for determining an operational state of an industrial plant includes acquiring alarms raised within the plant and adding them to a pool of important alarms, determining whether a physical state of the plant indicated by a first alarm causes a second alarm or meets a predetermined state-dependent condition and, if so, moving the first alarm to a pool of informative alarms; and determining the operational state of the plant and/or a corrective action for improving this operational state based on the alarms in the pool of important alarms.

Abstract: The invention relates to a melt filter (1) for filtering plastic melts, comprising a screen rotor (3) which is arranged such that it can be rotationally driven between two housing plates (2) and which has recesses (5) along a circular path (4) for receiving exchangeable filter elements (6), and comprising a melt channel (7) which penetrates the housing plates (2) in the region of the circular path (4) and is associated with the screen rotor (3).

Abstract: A network node for a wireless communication network, in particular for a wireless sensor network, includes a wireless communication device operable in a first communication mode in which the communication device emits; with a first transmit power, first communication signals for contactless communication with other network nodes in the communication network. The communication device is further operable in a second communication mode, in which the communication device emits, with a second transmit power, second communication signals for communication with a transponder, whereby the second transmit power is greater than the first transmit power. In the first communication mode, by the communication device there is detectable the presence of a transponder in the environment of the network node by the first communication signals.

Abstract: The present invention relates to innovative antifouling additives, to a process for producing them, to coating systems comprising the antifouling systems of the invention, to a process for producing the coating systems, and to the use of the antifouling additives and coating systems of the invention for preventing the underwater fouling of surfaces of objects which are in contact or come into contact with water.
