Abstract: A packaging machine (1) having at least one registration device is described, in particular a log-in device (13, 16) for checking the personnel-related access authorization. In order that a log-in procedure for gaining access to the packaging machine (1) is associated with the smallest possible expenditure of time and/or effort, at least one of the log-in devices (13, 16) includes a reading unit for wireless and/or contactless reception of transmitted information from wireless and/or contactless readable portable data storage media (12, 18), as well as an alternative input device for the wired input of information. A data storage medium is also disclosed.

Abstract: An apparatus for separating aerosols or particles from a gas stream composed of a flow housing through which the gas containing the components to be separated flows, a separator, which is arranged in the flow housing, and a corona electrode, which is provided upstream of the separator in the direction of flow. The corona electrode is located substantially outside the gas flow. An air volume stream from the corona electrode flows into to the gas flow to transport charge carriers generated by the corona electrode into a charging zone in the flow housing.
