Abstract: A method for communication between an external computer and a charging cable with an in-cable control box for charging battery-powered electric vehicles includes providing the charging cable with a data line for communication with the vehicle. A hardware interface between control box and computer allows access to the data line through the computer. Data for the control box is sent from the computer to the hardware interface, modulated by the hardware interface to the signal of the data line, and transmitted to the control box. Data for the computer is sent from the control box through the signal of the data line, converted by the hardware interface, and sent to the computer. The data is sent from control box to computer by modification of the pulse width of the signal of the data line and sent to the hardware interface, which forwards the data to the computer.

Abstract: A printing press and a method for controlling a printing press include rotatably mounted cylinders. At least two adjacent cylinders roll on one another through bearer rings. At least one of the adjacent cylinders can be rotated actively relative to at least one of the bearer rings by a setting device.

Abstract: A method and device for electrically braking an electric drive in a machine for processing printing material, includes a power electronics connected between the electric drive and a DC voltage intermediate circuit. A further electric braking device is switchable between the electric drive and the power electronics. Upon a failure of a power system, a computer initiates a generator-type braking operation through the power electronics. The further electric braking device is switched on upon the failure of the power electronics.

Abstract: An apparatus for feeding sheets in sheet-processing machines includes a transport belt which transports sheets from a first location to a second location. The transport belt can be driven at variable speed by a drive. The speed of the transport belt can be controlled by a control device in such a way that, through the use of a combination of at least two speed profiles, the number of sheets on the transport belt and the transfer of the sheets at the first and second locations can be adjusted. A printing press having the apparatus is also provided.

Abstract: A process provides for the safe operation of a printing machine. The printing machine has a first cylinder driven by a first motor, and a second cylinder driven by a second motor. The first cylinder accepts sheets of paper from the second cylinder or delivers them to the second cylinder by a gripper system. In the case of a deviation in the synchronized running between the cylinders, the gripper system is retracted at least in part far enough into the first cylinder that the possibility of a collision of the gripper system with the second cylinder is eliminated.

Abstract: A module for a machine for processing sheet printing materials, has interfaces for control communication, a memory unit which can be read and written and which contains the properties of the module, and also a communications device which is used for communication with further modules and/or a higher-order control system of the machine. The communications device is operatively connected to the memory unit.

Abstract: A method and a corresponding inking unit permit positioning of a roller into at least two different operating positions. The roller is, in particular, a vibrator roller of an inking unit for a rotary printing machine. The roller is positioned by controlling or regulating a magnetic bearing device in which the roller is mounted.
