Abstract: A mixer in particular for viscous elastic materials has a processing channel having an outlet opening at one end which can be closed. The materials can be transported and simultaneously mixed along the processing channel using a a transport device. A feedback channel branches off from the processing channel near the outlet end and feeds back into the processing channel at an upstream location so that the material mixture can be circulated though the processing channel and the feedback channel when the outlet opening is closed. In order to be able to measure rheological quantities of the mixture during the mixing procedure, the feedback channel is configured as a measurement path. Towards this end a pressure sensor device can be provided for in the feedback channel to measure the transport pressure in the transported material mixture at at least two mutually separated cross sectional locations of the feedback channel.

Abstract: Process for the continuous monitoring of waste gas from an incinerator plant, which contains volatile mercury halides and optionally metallic mercury in the form of vapor, with respect to the entire mercury content, of the waste gas taking a continuous test gas stream from the waste gas, cooling the test gas stream to form a condensate which contains a reducing agent, continuously passing the test gas stream into contact with the condensate to reduce the mercury halides contained in the test gas stream to metallic mercury by the reducing agent contained in the condensate, and subsequently determining the entire metallic mercury content by analysis of the test gas stream.

Abstract: Improved flue gas purification process features a heavy metal separating process, such as an anion exchange process, in which a scrubbing condensate is treated to remove at least the Hg contained therein prior to extracting the flue ash, which was previously separated and collected, with the scrubbing condensate to extract soluble heavy metals therefrom. A further heavy metal separating process, such as a cation exchange process, in which the scrubbing condensate after the extraction step is treated to remove at least one of Cd and Zn contained therein is also featured and may be performed after the extraction step or after solid/liquid separation of the flue ash and condensate from the extraction step.

Abstract: A process for the purification of flue gas generated during the combustion of waste materials has a first embodiment wherein soluble heavy metals are precipitated and recovered in a compact form and wherein the soluble heavy metal-free extraction residue is returned to the combustion system where noxious organic substances are pyrolyzed. In another embodiment, substantially all of the heavy metals from the flue gas are collected in a single solid residue, which residue may be thermally treated to recover mercury and the treated residues subsequently returned to the combustion system wherein noxious organic substances are pyrolyzed or combined in a hazardous waste stabilizing substance.

Abstract: An apparatus for analyzing flowable material in intermittent sequence comprises a hollow dosing sphere having a predetermined inner volume for forming samples of constant volume of the material introduced thereinto; a hollow radiation sphere connected to the outlet of the hollow dosing sphere; a radiation source supported within and centrally with respect to the hollow radiation sphere for a homogeneous activation of the sample introduced thereinto from the hollow dosing sphere; a hollow measuring sphere connected to the outlet of the hollow radiation sphere; and a detector arranged in the hollow measuring sphere for sensing the activity of the irradiated sample introduced thereinto from the hollow radiation sphere.
