Abstract: This invention relates to a display module for a modular display system that is highly configurable. The module is for displaying a model and includes a base for supporting the model and one or more sidewalls extending upwardly from the base to at least partially surround the model. The base includes a plurality of coupling elements for coupling the module to an adjacent module.

Abstract: The subject of this invention is a transfer suction roll (21) for transferring a material web with a perforated suction roll shell (22) that is pivot-mounted in roller bearings (25) and a suction box (24) mounted inside the transfer suction roll (21). The suction box (24) defines a suction zone (37) on the perforated suction roll shell (22) by means of seals (32). According to the invention, a suction hood (26) is arranged on the outer circumference of the transfer suction roll (21) through which air can be sucked out of the suction box (24) through the perforated suction roll shell (22).

Abstract: The color scanning signals generated by scanning the original are first converted into three primary color signals having actual color values in a predetermined color coordinate system corresponding substantially identically to theoretical color values of the original. It is only after this conversion that the primary signals or signals derived from these signals are converted to another color rendition system, or the gradation is altered, or the color rendition of individual colors in the overall image or in discrete areas is altered, or any other non-linear processing takes place.

Abstract: A method for electrostatic assistance of the printing process in printing machines, in which method a printing substrate, being of a material which is not electrically conductive, is passed between a printing cylinder coated with printing ink and a contact pressure roller which mechanically presses the substrate against the cylinder and which is provided with a non-conductive or weakly-conductive outer layer, during which procedure the application of a high voltage between the printing cylinder and at least one of the electrode arrangements running in a longitudinal direction to the contact pressure roller results in electrons and ions being sprayed by corona discharge onto the surface of the contact pressure roller, which, as a result of its rotating and/or its intrinsic conductivity conveys these charged particles into the printing gap and enables them to flow off over this gap, and also a corresponding printing machine.
