Patent DE-4127663-A1 (DE)
Inventor: LAUFENBERG ALFRED DR
IPC: G01N27/416
Filed: 1991-08-22
Abstract: The invention concerns a method of determining the concentration of an iodine/iodide-containing active substance in aqueous solutions intended for use in the cleaning or disinfection of containers such as bottles, drums, kegs, cases and tanks and/or pipe lines in the food-processing industry, as well as for industrial-scale cleaning in continuous washing plants, the concentration of the active substances in the solution being measured by determining the iodine/iodide content of the solution. The invention provides a rapid, reliable and accurate method which is not prone to interference and can be used on a continuous basis. In addition, it makes it possible to automate the process by which the active substance is kept at the required concentration. In particular, the method proposed can be employed in an integrated cleaning-in-place system. These advantages are achieved by the invention by virtue of the fact that the iodide-ion concentration in the solution is measured potentiometrically using electrodes which behave selectively towards iodide ions, and the concentration of the active substance calculated from the measurement results obtained, the iodine/iodide concentration in the solution lying between 0.1 and 1000 ppm, in particular between 1 and 20 ppm.

Title: Controlling melting and casting process for induction furnaces - utilising time deriv. of variation of temp. radiation without being dependent on characteristics of probes and crucibles
Inventor: STUERMER JOHANN
IPC: B22D46/00
Filed: 1991-09-27
Abstract: Controlling melting in a casting process, especially for determining the instant for pouring off the melt from an induction furnace comprises differentiating the variation of the temp. radiation (s) with respect to time (t). The max. value (U1) of the differential coefficient (ds/dt), occurring before the solidus point, is normed. Once the value (U1) is subsequently exceeded, a time interval (delta tz) - which is determinable beforehand - is started, and the pouring-off process can commence after the elapse of this interval. USE/ADVANTAGE - Used in general melting and casting installations, especially with small induction furnaces in fine casting technology (for example, dental technology). In contrast to known methods based on direct temp. measurement - which require extreme accuracy and exact knowledge of the casting temp. - it is not dependent on the characteristics of the probes and crucibles, and can be universally used.
