Abstract: A network of terminals, where each terminal is operable by a student in a group as a response apparatus, is in contemporaneous communication with a teacher station. The modes of operation include visual, i.e. hand writing, hand drawing and typing, as well as audio, in particular the voice of the user, which may contemporaneously accompany the visual, such as when explaining what is being drawn. Such an apparatus can also be used by a teacher to author a lesson, including graphics and audio, providing information and questions which are recorded at the teacher station. The communication means between the student apparatuses and the teacher's station is in a preferred embodiment of the invention via an 802.11 wireless gateway when the students are in the same room as the teacher or in close proximity, or via the Internet especially in the case where individual students are remotely located from the teacher.

Abstract: A cut-off register controller is usable in a longitudinal fold forming assembly of a rotary cylinder printing press that is provided with at least one form folding assembly plane which consists of two adjacently defined longitudinal fold formers. The web ribbon or the partial web ribbons, which are longitudinally formed and folded by the formers are collated at an exit of the former assembly by the operation of a roller pair and are formed into a combined ribbon. That combined ribbon is then fed into a folding apparatus. A number of control circuits are located downstream of the formers and corresponding, in number, to at least the number of formers. The control circuits are usable for controlling the cut-off register of the printed web. Each control circuit has at least one detector and one adjusting member which is usable to adjust the distance between the web or stand and the former.

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 method is used for adapting an inking unit of a printing press. During a setup phase for the printing press, at least a first actual value with regard to an ink application that is set at the inking unit and that is applied to the printed material, is determined by use of a first measuring device. The inking unit is initially set using this first actual value. During continuous printing of the printing press, a plurality of second actual values, with respect to a printed image formed on the printed materials, are determined using a second measuring device which is different from the first measuring device. These second values are fed to an ink adapting device for the inking unit. At least one of these several actual values, which corresponds to the setting mode in the setting phase, is set in the ink adjusting device as its setpoint value. The ink adjusting device detects deviations of the other second actual values for this setpoint value and adjusts the inking unit to minimize these deviations.

Abstract: A printing device, which is usable to produce printed products, is supplied with a material web of a predetermined length. The length of the required web is defined by the printed product to be produced. The material web is assembled from several partial webs, having defined lengths. The supply of these partial webs to the printing device is provided automatically with the use of a material management system. A control unit of this system determines the length for the partial webs that have been chosen for a certain production request. These partial webs are sent to the printing device in a certain sequence so that the last one of these partial webs to be used has the least web length of the several partial webs. The minimum length of the last partial web is determined by an end of the partial web finishing the production. This sequence is determined, at the earliest, after the cycle time has ended.

A locking mechanism for the piston rod can be engaged and disengaged by the use of fluid pressure.

Abstract: A printed image is produced at least one printed image location using a printing machine with at least one illuminating device that produces at least one printed image at a number of printed image locations. These respective printed images belong to the same page of a printed product to be produced by the printing machine. This page of the printed product exists in the form of a file containing image data before it is produced as the printed image. That file contains image data of all of the printed images of the page of the printed product. A raster image processor is aligned with each printed image location and converts only image data of the printed images of the page of the printed product into raster data, with that printed image being assigned to a respective printed image position. A network is provided for use in the electronic communication of at least image data. Each raster image processor is connected to this network by an interface which receives data.

Abstract: A page of a printed product having a plurality of information fields arranged in different printed columns is provided. At least one perforated line, extending parallel to the height of the page, is generated in the page between at least two printed columns. The at least one perforated line is formed over the entire height of the page. At least one printed column, along with its at least one information field, can be completely separated from the remaining part of the page via a separation process to be performed along a single such perforated line. The perforated line to be used to execute the separation process extends through a pictogram that is situated along both sides of this perforated line. The pictogram visualizes the position of this perforated line. A longitudinal perforation device for a web-fed rotary printing press can be used to produce this page and has at least one perforating blade for generating the perforated line. The longitudinal perforation device is configured as an autonomous module.
