Abstract: The invention relates to a method and a transmission device for mobile radio transmission of measured data, the transmission device including a transmitter and a receiver which implement a Wi-Fi transmission process according to communications standard IEEE 802.11. The transmitter has a Wi-Fi module which is configured for allocating a vendor specific element of a beacon frame with measured data and for transmitting the measured-data beacon frame. The receiver includes a different Wi-Fi module which operates in a promiscuous mode and is configured for receiving and recording all beacon frames; for filtering the measured-data beacon frame; and for assigning the measured-data beacon frame to the corresponding transmitter.

Abstract: The invention relates to a method for transferring data between an electrical measuring device (2) and a control computer (4), the data being transferred via a Modbus protocol (20) that is tunneled in the HTTP protocol (12) in connection with a TCP/IP transmission protocol (14). The principle idea of the present invention is based on HTTP (12) being used as an external protocol and a Modbus protocol (20) being integrated, i.e. tunneled, into the HTTP protocol (12) as payload.

Abstract: An apparatus for overlapping sheets and depositing them in a stack has a conveyor for transporting the sheets in a horizontal travel direction along a travel path toward a stacking region at a rapid feed speed. A braking device on the path upstream of the stacking region can grip the trailing edge of a one of the sheets. At least one supporting air bar extends above the path into the stacking region and has nozzles from which compressed air exits in the sheet travel direction. A suction belt above the travel path between the braking device and the stacking region is movable in the travel direction at least at the rapid feed speed and has suction ports that can be switched on and off cyclically.

Abstract: The invention relates to an apparatus for imbricating sheets and depositing them on a stack (23), having a braking device, which is arranged upstream of the stacking region and acts in each case on the trailing edge of a supplied sheet (5) and having at least one transporting-air bar (19), which extends into the stacking region above the supply plane and has nozzles which expel compressed air.
