Abstract: A door lock, in particular a motor vehicle door lock, which is equipped with a locking mechanism that substantially consists of a rotary latch and at least one pawl. Each of the two locking mechanism parts is rotatably supported on a base about a respective axis. For this purpose, a bearing surface of each locking mechanism part slides along a fixed support body. According to the invention, the support body is provided with an open bearing trough for receiving the bearing surface.

Abstract: A latch for a motor vehicle, in particular an electrically operable latch, comprising a locking mechanism having a catch and at least one pawl, it being possible to ratchet the catch in at least one main ratchet position by means of the pawl, and a further ratchet element located between the catch and the pawl in the engagement region and arranged on the catch, the ratchet element being pivotably accommodated in the catch.

Abstract: An electromotive drive for motor vehicle applications, in particular for applications for and in a motor vehicle lock. For this purpose, the drive is equipped with an electric motor, a drive disk which can be actuated by the electric motor and can be rotated about an axis, and at least one spring assigned to the drive. The spring transmits a force to the drive disk which aids the drive within the scope of the invention.

Abstract: A door lock, in particular a motor vehicle door lock, comprising a locking mechanism consisting substantially of a catch and at least one pawl. Each locking mechanism component is mounted on a base in a rotatable manner about an axis. Additionally, a fixed support body is provided for at least one locking mechanism component. According to the invention, the locking mechanism component is designed to be rotatable about a bearing pin at a distance from the support body during a normal operation and comes into contact with the support body solely in the event of a crash with a simultaneous deformation of the bearing pin.

Abstract: A motor vehicle lock, in particular a motor vehicle door lock, which is equipped with a locking mechanism essentially consisting of a rotary latch and a pawl. Furthermore, an actuating lever chain for the locking mechanism is provided. The actuating lever chain has at least one actuating lever, a coupling element, and a trigger lever on the locking mechanism side. Furthermore, an inertia element is also provided for acting on the coupling element at least in the event of a crash. According to the invention, the coupling element is disengaged during normal operation and is only engaged in the event of a crash by means of the inertia element.

Abstract: An apparatus for safely operating at least two components which are movable relative to one another in a machine for processing printing materials, includes drive motors each driving a respective one of the movable components. At least one control computer detects movement of the movable components. The control computer is set up in such a way that, if a spacing is reduced between the movable components, at least that movable component, which is the cause for the reduction in the spacing between the movable components, is brought to a standstill. A printing press having the apparatus is also provided.

Abstract: A method for operating a machine that processes printing substrates in sheet form, in particular, a printing press, including a delivery device (1) which contains a drive (2) for conveying the substrate sheets and at least one opening (8) through which the substrate sheets are conveyed from the inside (4) of the delivery device (1) to an externally accessible region (6), and further including a control device which controls at least one closing device (7) for opening or closing the opening (8) and which is operatively connected to the drive (2) of the delivery device (1). Also provided is a device for carrying out the method. The present invention has the feature that the opening (8) is closed or is closed by the control device when no substrate sheet is conveyed through the opening (8).

Abstract: A suction system for supplying an internal combustion engine with combustion air, especially in an automobile. The suction system includes at least one separate air collector from which individual suction pipes each lead to the air inlets of the respective cylinders of the internal combustion engine. The suction pipes are configured as ram tubes for the top speed areas of the internal combustion engine. At least one compensation flap is located in the air collector. When closed, the compensation flap divides the air collector to provide a long pre-suction section and when open, instead of a long pre-suction section provides an air collector with an increased volume.
