Abstract: In order to print a print web (1) by means of a plurality of printing groups (5), the print web (1) is guided in the region of the printing groups (5) on a support band (10) which is transported at the same speed and multiple printing is carried out by printing groups (5) arranged next to each other in the direction of transport of the support band (10). Preferably, the printing groups (5) are arranged on vertical machine stands (6), which are disposed near to each other and parallel to each other, and terminate with plate cylinders (7) at the same level, thereby enabling the print web (1) to run through a print zone (3) in a substantially horizontal manner.

Abstract: With many coated plates, in particular zinc (galvanized) and organic coated sheet metal as are employed in the automobile industry, the coating material has a significantly lower boiling point than the melting point of the sheet metal material. Therefore in the case of laser welding of this type of sheet metal with zero gap in the overlap abutment area to a explosion like vaporization of coating material, which take along or entrain molten sheet metal material and strongly damage the quality of the joint. For improving the connection it has already been proposed that no gap be provided between the sheets, but rather these are positioned directly over each other and then first by means of first laser beam to warm until vaporization of the coating and subsequently to weld the uncoated sheets by means of a second laser beam. The disadvantage therein is above all the elaborate apparatus set up or complexity for the two required optical systems.

Abstract: With many coated sheets, in particular zinc-coated sheets as used in the automobile industry, the coating material has a much lower boiling point than the material of the sheet. On welding said sheets together the above leads to explosive evaporation of coating material which seriously affects the quality of the connection. In order to improve the quality of the connection it has already been disclosed that narrow gaps between the sheets can be produced by means of spacers, through which the coating material can escape. The spacers can be produced for example, by means of laser bombardment of the sheets. A disadvantage is the relatively long time necessary for machining, which causes large costs in particular for serial production. The aim of the invention is to reduce the time necessary for machining the sheets whilst at least maintaining, preferably improving the quality of the machining.

The method comprises: displaying a starting region of the matrix, the starting region having one or more rows with each row having a field corresponding a data record; determining a field corresponding to the matrix position which the computer user indicates via a first user interface; obtaining a data record to which the determined field is related; identifying the rows of the matrix relating to the obtained data record; displaying, on detection of a user request via a second user interface to continue to display, a second region of the matrix which contains at least one identified row.

Abstract: The administration of a computer system of server and services is supported by providing entries in an administration log. The log helps to track the cause of a failed service to the relevant setup change of a server. In one aspect, the steps for perform such a tracking includes receiving input data that describe a setup change of a server and input date that identify the server, determining the service that is affected by the setup change, and writing a log entry that includes the input data and the identification of the affected service. In a further aspect, writing of the log entry is done in two parts, where the first part includes the input data that identify the server, the affected services, and a navigation link to the second part and where the second part includes the input data that describe the setup change.

Abstract: For increasing the load bearing capacity of spot-like weld seams for producing a durable joint between at least two components, it is known to lengthen this linearly, that is, to weld with a longitudinal orientation extending more than 30 mm. Such linear weld seams, however, do not endure high loads. The task of the present invention comprises providing linear weld seams with increased load bearing capacity and a process for their production. This task is solved by a process specifically for increasing the load bearing capacity of a linear weld seam for producing a durable joint between at least two components, wherein the location with the highest probability of a weld seam break is determined and then, at this location, a discontinuity is introduced into the weld seam, in such a manner that the tangent of the connecting line exhibits an angle of 15° or more.

Abstract: The invention relates to a device for electrically controlling an automatic weapon. A housing (2) is laterally fastened to the weapon in a manner that enables it to be detached. An electric drive motor (1) is mounted on said housing and drives a threaded spindle (6) running parallel to the firing direction. A spindle nut (10) can be displaced on said threaded spindle. A driver (9) is placed on the spindle nut in such a manner that a draw bolt coupled to the weapon breech is located in its trajectory and can be displaced out of an initial position back into a drawn position when the spindle nut (10) is in the extreme position. In the drawn position, the draw bolt is retained by a catch lever mounted on the housing. The catch lever is arrested when the spindle nut (10) is in the extreme position that corresponds to a safety state of the weapon.

Abstract: In the manufacture of automobile body parts the application of anti-corrosion base coating by means of cataphoretic painting (KTL) is well known. However a gap occurs in particular in the contact areas of the components joined to each other, into which the cataphoretic paint can penetrate only incompletely or possibly not at all. Thus, this type of gap is conventionally sealed following cataphoretic painting, in order to ensure corrosion protection for the entire assembly. The present invention makes it possible to dispense with the sealing in the production of an assembly of joined conductive components and nevertheless to ensure a sufficient corrosion protection. This is achieved by introducing topographic changes in the components projecting from their surface in the known contact areas and then joining these components such that they are spaced apart by the projecting topographic changes in such a manner that during cataphoretic painting the paint wets the entire surface of the assembly.

Abstract: When laser beam welding two or more work pieces, the weld seam is usually visible on the work piece that is farthest from the laser beam, on the side of this work piece away from the laser beam. If this side is in an exposed area, then it must be reworked, which is expensive. The task of the present invention therefore consists of providing a method and a device for laser beam welding, with which a laser-welded seam can be formed without being so noticeable. The task is solved by determining the critical energy input per area unit and time unit into the work piece to be welded, above which an appearance of the welded seam to a degree exceeding a predetermined level will occur on the side away from the laser beam of the work piece that is farthest removed from the laser beam, and that the laser beam is controlled or regulated in such a way that the critical energy input per area unit and time unit is not exceeded.

Abstract: During welding with high output power, the gaps between the pieces being joined may not exceed a maximal gap width. It is the task of the present invention to provide a process for laser beam welding, which on the one hand ensures maintaining (not exceeding) a maximal gap width between the sheets and on the other hand makes possible a maximal utilization of the achievable welding speed. This task is solved in that the sheets, prior to welding, are first spot welded, wherein they are clamped only during this spot welding in order to ensure the maintenance of a maximum gap width.
