Abstract: In line circuit breakers with a combined overcurrent/short-circuit current tripping device, tripping should take place in a well defined manner in the case of an overcurrent and in the case of a short-circuit current. For this purpose, gaps (A, B) need to be set precisely. If the housing is made from a cost-effective housing material such as thermosetting plastic it is subject to shrinkage. As a result, the mentioned gaps may change. An armature (24) is mounted in such a way that it changes its rest rotary position in the event of shrinkage of the housing. A magnet yoke (28) as part of the overcurrent/short-circuit current tripping device is mounted and shaped in such a way that the rotation is compensated for precisely, so that the mentioned gaps do not change despite the shrinkage.

Abstract: A product section is produced in a printing machine that has at least one former. A web or a partial web of material is guided over the former. At least one web or one partial web is initially guided over a plow fold device and then over one, or another odd number of turning bars. This at least one web or partial web is then united, without passing through the former, and on a side that has been folded in by the plow fold device, over at least one guide roller as a partial strand with a partial strand that was guided over the former as a strand bundle before this partial strand is cut transversely in a transverse cutting direction into product sections.

Abstract: A web-fed rotary printing machine has at least one printing unit and at least one Turning bar that is usable to redirect a travel direction of a web that is to be conveyed. The turning bar has an effective length, for redirecting the web. A projection of this Effective length corresponds with the width of the incoming web which is of at least four Adjacently arranged printed pages in newspaper format.

Abstract: The invention relates to a electromechanical switching device having two movable contact elements interacting with a fixed contact. Said switching device has a housing. When viewing a fixing side from the top, said housing is divided into two areas bordering with a longitudinal side of the housing, one of the movable contact elements and the corresponding fixed contact being located in said areas, wherein each of the housing areas has a narrow partial area and a broad partial area bordering therewith. The broad partial area of the first housing area is adjacent to the narrow partial area of the second housing area and the narrow partial area of the first housing area is adjacent to the broad partial area of the second housing area. The actuation directions of the movable contact elements are directed opposite each other.

Abstract: At least one of a transverse elongation and a longitudinal elongation of a printing material are compensated for. The printing material passes through serially arranged printing couples in a printing press. A component of the transverse elongation is compensated for after passage of the printing material through a first printing couple and before its entry into a second printing couple. This can be accomplished by the use of a framing controller. Alternatively, this transverse elongation can be compensated for by the displacement of at least one printing forme which is situated on a subsequent printing couple. The printing forme can be displaced transverse to a production direction of the printing material, relative to a reference mark on the printing material. An elongation of the printing material, which is known at the time of image generation on a printing forme of a subsequent printing couple can be compensated for by proper configuration or positioning of the printed image on the printing form.

Abstract: A rotary offset printing press has at least one printing unit which is used to print a web with six printed pages arranged in an axial direction next to each other. The printing press also includes a folding apparatus. A transport cylinder of the folding apparatus is arranged with a periphery that can also receive at least six section lengths of the printing product, which six section lengths are arranged in the direction of the periphery of the transport cylinder.

Abstract: A printing machine includes at least one printing group, one folder and at least one turn-and-mix stage that supplies the printed web output from the printing group to the folder. A web path from the printing group to the folder, when projected into a horizontal plane, is bent or deviates in the area of the turn-and-mix stage. The turn-and-mix stage or superstructure, includes a horizontal cutting device at an input side, for use in cutting the web into at least two partial webs. At least two horizontally displaceable turning bars are provided, and the partial webs pass around these turning bars.

Abstract: A printing machine is comprised of several printing groups, at least one dryer and at least one folding apparatus. At least two of the printing groups are arranged side by side in the axial direction of the cylinders in the printing groups. A longitudinal direction of the dryer extends perpendicular to the axes of rotation of at least one cylinder group which defines a printing gap.

Abstract: A modular device comprises a housing and a terminal arranged therein with a clamping screw, a pressure plate and clamping frame, a first recess on the connection side for transversely receiving a busbar passing through the housing and clamping frame, and the insulating gap between the outer edge of the clamping frame within the housing and the outer side of the adjoining closed housing side being smaller than the air insulating gap between the outer edge of the clamping frame in the region of the recess and the outer side of the adjoining housing side.

Abstract: In order to achieve optimized insulation resistance in a rail mounted device (1) having a recess (13) for a bus bar, a terminal (17) having a narrowing in the area of the recess (13) is used so that the distance of the air insulation relative to an adjacent device is maintained.
