Abstract: The invention relates to a method for controlling and/or monitoring a compressor system comprising several components, namely one or more compressors (11, 12, 13) and one or more peripheral devices (14 to 21), and also a control/monitoring unit (22), wherein the compressors (11, 12, 13) and peripheral devices (14 to 21) are arranged or connected in a certain configuration. The method distinguishes itself in that in a measured-value-capture step, measured values are captured within the compressor system or the components, in an allocation step, context information is allocated to the measured value or measured values in advance, simultaneously, or after the measured-value capture, in order to standardize the measured values, and in an evaluation step, the measured value or measured values standardized by the context information is used in a control, monitoring, diagnostics, or evaluation routine.

Abstract: A method for controlling and/or monitoring a compressor system is provided. The compressor system includes one or more compressors and one or more peripheral devices. The compressors and peripheral devices are arranged or connected in a predetermined configuration. The compressor system is controlled and/or monitored by a control/monitoring unit. The method involves creating one or more derived models on the basis of one or more initial models of the compressor system that are based on a P&I diagram. The derived models take into account the operative interrelationships among the individual compressors and peripheral devices, and optionally also dynamic processes. The one or more derived models form the basis for subsequent control, monitoring, diagnosis or evaluation routines.

Abstract: A communications system, with a network, is usable to transmit at least image data to at least one illuminating device. The illustrating device illustrates a printed image location in a printing machine. A network is provided for the control and/or monitoring of the printing machine. A network for the communication of data to be processed in a pre-printing stage is also provided in that pre-printing stage, which prepares that image data. These two networks are connected to the same signal line or transmission link or are each constructed identically, with respect to their data transmission properties. The communications system, with the network, can control or monitor a printing machine having a number of sections, with at least two of these sections having a section controlling device. These section controlling devices are connected to the network, and control or monitor their respective sections. The network has the same data transmission properties in each of these sections.

Abstract: A state information system for acquiring measured values of chemical and/or physical variables during the production, processing or finishing of a material, in particular in the case of a printing material web in a web-fed press, includes at least one sensor for recording the chemical and/or physical variables, the state information system being provided on or in the material such that the operating process carried out with the material remains unaffected by it.

Abstract: In order to create preconditions, in a web-fed rotary press, for good format variability of the printed products and economic utilization of the printing material, at least two printed pages of different heights are arranged in the circumferential direction on a form cylinder.

Abstract: The present invention relates to a device to prevent damage to printing groups of web-fed rotary presses that print webs fed by a cylinder which is placed on a reel changer. A fault detector is provided that has a deflection device next to both web edges. It can create a deflective force transverse to the web plane transport, which can be overcome by the tension of the web during normal operation. A monitor is also provided that detects changes. With the aid of this device, damage to printing groups can be prevented (especially arising from defects occurring during reel exchange) by locating the fault detection device in front of the first printing group of the web-fed rotary press, and each of the two monitors of the fault detector is designed as an optical sensor that emits a signal which depends on shading by the web, and its optical axis is tilted in the lengthwise direction of the web in relation to the direction of the deflection force that is essentially perpendicular to the transport plane of the web.

Abstract: In carrying through quality management while printing a web on a rotational roller printing machine high accuracy is obtained by a periodic returning, simultaneous measuring of color density and spectral distribution in at least one selected point of the periodically returning printing pattern; the continuous registration and storing of the measuring results over the entire duration of the production process; an analysis of the measured results by predetermined criteria at least at the end of production. For doing so a device is provided with at least one adjustable measuring head spanning the width of the printed web, containing a spectrometer and a light source; the measuring head can be activated depending on the product by means of an encoder assigned to the rotational roller printing machine. Further, a control device is provided that can continuously record the measuring signals of each measuring head.

Abstract: In the case of a web breakage detector for web processing machines and more particularly for web feed printing machines, comprising a device for monitoring the web tension and adapted to produce a signal in the event of the web tension decreasing, a high degree of reliability and ease of operation are possible if said monitoring device is designed in the form of a pressure measuring device, which comprises a web pressure sensor for detecting the pressure in a gap delimited during normal operation on the one hand by the web and on the other hand by a stationary cover passed by the web, such sensor being adapted to produce a signal in the event of a pressure drop occurring in the gap.
