    Abstract: The invention relates to a measured value acquisition and processing unit (5) that facilitates the acquisition and processing of very small measuring signals in the range of interfering signals, such as, for example, noise, spillovers, etc. This means that the useful values to be detected usually contain interfering portions. The inventive measured value acquisition and processing unit (5) separately acquires these interfering portions by means of a switch element (10) disposed in the area of feed of the measured signals by means of which the measuring circuit is short-circuited in such a manner that the measured signal is not coupled in but only interfering signals that might occur in the measuring circuit are detected. The inventive method provides a large range of dynamic ratio for the detection of measured values at low costs.

    Abstract: A protective device is disclosed for combination with an electrical switching device including a main current line or for integration in such a switching device. In at least one embodiment, the protective device includes a switching element and a switching apparatus, which is provided for the actuation of the switching element and is influenced by a current flow through the main current line. In at least one embodiment, in order to influence the switching apparatus, a current transformer is integrated in the main current line and an electrical resistance of a secondary winding surrounded by the current transformer can be measured. A method for operating a protective device is also disclosed wherein the switching apparatus is triggered so as to actuate the switching element if the measured resistance reaches or exceeds a predetermined or predeterminable threshold value.

    Abstract: Samples of fine dusts in air or gases are collected for analysis and measurement by atomic absorption or atomic fluorescence by conducting the air or gases across a surface of a sample container and causing the dust to be deposited electrostatically on the said surface. The sample container is then heated to a temperature sufficient to vaporize the particles of dust, and the vaporized particles are then brought into the beam path of an atomic absorption or atomic fluorescence spectrometer.
