Abstract: The invention relates to an inertization device for establishing and maintaining an inertization level in a protective room. The inertization device has a controllable inert gas system for providing inert gas, a first supply pipe system connected to the inert gas system and the protective room to supply the inert gas to the protective room, and a control unit to control the inert gas system such that a presettable inertization level is established and maintained inside the protective room. In order to raise the inertization level inside the protective room rapidly to an accessibility level without requiring major structural measures, a valve controlled by the control unit is connected to the inert gas system and the first supply pipe system to supply the exhaust air prepared by the inert gas system as fresh air to the protective room.

Abstract: A lubricant distributor in which the path of movement of a metering piston may be continuously determined by means of an entry body-coil assembly, whereby the entry body moves relative to the coil with movement of the metering piston. The current position of the metering piston may preferably be worked out in a computing unit. Means for indicating the current position of the metering piston can also be provided. With the aid of the invention, constant monitoring of the operation of a lubricant distributor and thus the detection of operational faults are possible in a continuous manner which may be centrally analysed. The conveyed volume, which is dispensed precisely at each lubrication or friction point, may be determined on each working stroke so that, in particular, insufficient lubrication and faulty lubrication may be avoided.
