Abstract: A conveying system to be used in the printing industry, especially in mailroom technology, includes a revolvingly driven conveying member that is provided with supporting elements that are fixed to a traction rope in a stationary and optionally torsion-proof manner. The conveying member can be provided with another rope that has the same length as the traction rope, revolves substantially parallel thereto, and is used as a guide rope or second traction rope. Grippers that are disposed laterally on the belt-shaped conveying member, which is formed by ropes and supporting elements, are arranged on the supporting elements in order to grab and hold individual printed products or groups of printed products. The conveying member is deflected onto different deflection planes via guiding devices while being twisted between such deflections such that the three-dimensional position of the supporting elements and the conveyed printed products can be modified.

Abstract: A stack-like arrangement of printed products with folded edges, in which arrangement the printed products are all arranged with identical orientation, has an increased stability, if it comprises stack sections, within which the folded edges of the printed products indeed lie on top of each other, but wherein the stack sections are arranged displaced in relation to each other, such that the stack sections with folded edges protruding from the arrangement alternate with stack sections with edges opposite the folded edges protruding from the arrangement.

Abstract: The invention relates to a device for receiving printing products (6, 7, 8, 9) in a transfer zone (37). Said device comprises at least one receiving element (1) that has a support element (2), a base element (3) and a bearing element (4), said support element (2) and base element (3) being able to support printing products (6, 7, 8, 9) laterally and from below and the bearing element (4) being able to receive printing products (6, 7, 8, 9) astride said element. According to the invention, a deflection element (5) is provided which can preferably deflect a printing product (6, 7, 8, 9) that is fed to the receiving element (1), in such a way that at least one part of the fed printing product (6, 7, 8, 9) is positioned on the side of the received printing products (6, 7, 8, 9) facing away from the support element (2).

Abstract: The invention relates to a piston pump, having a piston that has a longitudinal bore, that includes a valve seat face upon which a valve closing body is pressed by a valve spring. The valve spring is a helical compression spring, whose winding diameter increases from a winding end that engages the valve closing body to a winding end that rests on a spring seat face formed in the longitudinal bore of the piston. The piston pump of the invention has the advantage that the valve closing body along with the valve spring can be installed in the piston in an axial motion; the valve spring is directly accessible, and a correct seating of the valve and valve spring in the longitudinal bore can be checked visually after installation.

Abstract: This invention relates to a piston pump in a brake system having a piston, which is drivable in a reciprocating motion in a cylinder by an eccentric tang. To avert damage to a ring seal, a support ring is provided which keeps the ring seal spaced apart from a guide sheath for the piston in the cylinder by a distance that is at least as long as a stroke length of the piston. This prevents running scratches on the piston from coming into contact with the ring seal.

Abstract: A reciprocating pump including a piston through which fluid can flow. The piston includes an inlet valve which presses a valve ball against a valve seat in a longitudinal bore in the piston. One end of the piston has a cap-shaped support elements attached thereto against which the inlet valve spring is supported and which engage around an end behind an undercut in the piston.

Abstract: A contact arrangement has a contact spring which is prestressed against a seating edge of an actuation element by a prestress bend. The pre-stress bend lies at an angle of between 0 through 30 degrees relative to the seating edge so that roll-off is produced at the contact location. Such contact arrangement is especially advantageous for switching high-current loads since roll-off at the contact location reduces the welding tendency and makes an easier break-open of the contact when the contact is opening if there is a slight welding of the contacts.

Abstract: The relay exhibits a coil body on whose one flange an armature retaining element is integrated over elastic stays. A bar-shaped armature is secured in the frame-like armature retaining element, whereby the elastic flexural stays serve as a bearing for the armature. Additional fastening parts for the armature are thereby eliminated. A friction-free armature seating also thereby derives.
