Abstract: An exemplary embodiment of an apparatus for detecting microbiological activity in an industrial process may include a plurality of satellite units, a processing unit, and a main analysis unit. Each satellite unit may be configured to sample a liquid from the industrial process at a plurality of respective locations, periodically analyse a sample, carry out an impedance analysis to count and measure the size of particles passing through an orifice, and generate sample results data corresponding to the number and size of particles in each sample. The processing unit may be configured to compare the sample results data to a predetermined criterion and to generate an alert signal if the particle data is outside of the predetermined criterion. The main analysis unit may be configured to carry out a combined impedance and electromagnetic emission analysis of a sample of liquid from the industrial process following generation of the alert signal.

Abstract: The present invention refers to a method for producing a glass body with high silicic-acid content by drawing a softened glass mass from an elongated, substantially cylindrical crucible in that SiO2 granules are supplied from above into the crucible, the SiO2 granules are heated to a softening temperature, so that the softened glass mass which comprises a melt surface is formed, the softened glass mass is drawn off via a bottom opening of the crucible so as to form a glass strand, and the glass strand is cut to length to obtain the glass body, wherein due to the supply of the SiO2 granules a bulk heap is formed that covers the melt surface in part while leaving a melt edge, and wherein the melt surface is optically detected.
