Abstract: An energy supply is provided along a route with at least one distribution station, wherein a first voltage is applied at the input and a second voltage at the output. The second voltage is lower or higher than the first voltage. A plurality of components are arranged along the route. A component, which is supplied with the second voltage, includes a power supply unit for transforming the second voltage into a third voltage.

Abstract: In a method and network for the analysis of synchronized data traffic, at least one network participant stores sent and/or received data packets in a mirror memory, and the data in the respective mirror memories are frozen and made available for evaluation via the entire data network, upon the occurrence of a trigger event in at least one of the active network participants, while maintaining the synchronized data traffic.

Abstract: A system includes a plurality of electrical switches. Every switch is associated with at least one monitoring device for detecting the respective switching condition of the switch. All of the monitoring devices are interconnected through a data connection through which the switching conditions of all of the switches are made known to every monitoring device.

Abstract: A clock signal recovery device has a digital data signal input for the input of a digital data signal and a clock signal output for the output of a recovered clock signal. The digital data signal has a given nominal clock signal frequency. The clock signal recovery device is a digital circuit.

Abstract: A depot or a storage facility for a plurality of material rolls, which rolls are intended for further processing in a processing machine, includes two outer shelving blocks in addition to at least one inner shelving block that is situated between the two outer shelving blocks. A storage location of the inner shelving block can be loaded or unloaded by a retrieval device which can access the shelving block from both longitudinal sides of the shelving block.

Abstract: In order to check the functionality of a conventional current converter at low cost, a device for checking a current converter is provided. The current converter includes a test current conductor and a test pulse circuit. The latter has an energy storage device, a charging device for charging the energy storage device and a switching element for discharging the energy storage device via the test current conductor. As a result, a discharge current can be generated in the test current conductor, wherein an evaluation unit for detecting a current converter signal caused by the discharge current is provided.

Abstract: A system for checking the loading of a print forme magazine, which stores at least two print formes, utilizes at least one code reader to read a code which is carried by the print formes. The code reader reads the coding of the printing formes in a secondary region. The coding of at least two printing formes, which are arranged adjacently, horizontally or vertically together, is read by the code reader. The code reader has an image sensor and an illumination system for lighting the secondary region. A system is also provided for transporting at least one print forme stored in the print forme magazine to a cylinder. An analytical unit can be connected to the code reader, or to another registration device, and stores information regarding the transport of each printing forme, that is stored in the print forme magazine, to the cylinder. The analytical unit that may be connected to the code reader is provided with a signaling device.

Abstract: A processing machine, such as a printing press, is supplied with materials, such as rolls of paper, under the control of a control system. The control system is of a higher order than either of the material supply system and the processing machine. It is connected to both the supply system and the processing machine for transmitting data using signals.

Abstract: In a method and network for transferring data and signals between terminal equipment via one or more switching stations, the data and digitized signals are combined in cells, with each cell having a header in which connection information is contained that designates a transmission or routing target. The terminal equipment and switching stations are synchronized so that the cells are transferred in a synchronized manner via one or more switching stations. Signals and high quality of service (QoS) data thus can be transferred through the same network.

Abstract: The tension of a web in a multi-web system is regulated. At least two webs initially run through a first processing step independently of each other and are subsequently combined with each other to form one resultant web strand. The web tensions of these two initially independent webs are adjusted to each other through a first regulation process. Each of these webs has its web tension regulated on the separate web path by a dedicated second regulation process which is different from the first regulation process.

Abstract: Tension in a web of material that is passing through a web treatment machine, such as a web-fed rotary printing press, is controlled. The desired value for the web tension is modified to counteract defects that may influence web tension during production operation of the web treatment machine. The modification of the web tension is done in advance of, or concurrently with the arrival of the defect that influences the web tension.
