Patent DE-4231777-A1 (DE)
Inventor: TACKE MAURUS DR
IPC: G01N21/72
Filed: 1992-09-23
Abstract: In a flame spectral analysis process by optical of measurement emission, the relatively narrow-band emitted radiation of a flame (1) and/or its waste gases, and relatively wide-band components of a background or parasite radiation (3a/3b) also present are separated by an optical narrow-band filter (4a, 4b) and the radiation passing through the filter (4a, 4b) is detected. This invention should allow rapid, reliable and highly sensitive spectral emission analysis to be carried out, so that, for example, even low noxious substances concentrations may be detected and optimum operational conditions may be set. For that purpose, the emissions from at least two gaseous components of the same flame (1) are detected simultaneously and independently from each other with a natural flickering frequency. The radiation (5a, 6a) passing through a first narrow-band filter (4a) tuned to a first gaseous component is received by a first detector (7a) and a first detector output signal is formed, and the radiation (5b, 6b) passing through a second narrow-band filter (4a) tuned to a second gaseous component is received by a second detector (7b) and a second detector output signal is formed. A correlation between the time functions of the detector output signals due to the natural flickering frequency of the flame (4b), which depends on the gaseous components, is used when the detector output signals are further processed for suppressing the detector output signal components generated by the components of the background or parasite radiation passing through the filter (7b). Also disclosed is a device for spectral emission analysis of flames and/or their waste gases.

Title: Coil for generating an alternating magnetic field
Inventor: HALSTRUP ERWIN
IPC: G01N27/72
Filed: 1993-07-09
Abstract: A coil (1) serves to produce an alternating magnetic field (2), one partial region of which serves as a measurement field (5) in which a specimen (6) to be examined can be positioned. This specimen can be examined with regard to dielectric properties. Moisture-level measurements can furthermore be carried out. The coil has a winding which is connected to an AC voltage source (9) and has at least two terminals, the first terminal being at a low potential (L) which is earthed or close to earth and the second terminal being at a high potential (H) which is higher than the low potential. In the case of a multilayer winding, the winding layer (8) connected to L potential faces the measurement magnetic field (5) which is produced and further winding layers follow on in layers towards the rear end. The individual winding layers are in this case designed virtually as disc windings. The last winding layer, remote from the magnetic field (5) is connected to the high potential (H) of the AC voltage source. By virtue of this winding design, a geometrical field separation between the alternating magnetic field and the electric field is achieved and mutual interference can thereby be reduced as far as possible. <IMAGE>
