Abstract: The object of the invention is a more energy-efficient system for utilizing waste heat and residual gases from the engineered generation of carbon compounds, such as carbon black, graphite or from sugar pyrolysis, using a coupling of energy-heat or a thermal heat-generating plant for generating electrical energy, in particular for operating melt furnaces, and/or for utilizing the waste heat in endothermal processes. The invention also relates to the use of waste heat.

Abstract: The invention relates to a spectral fluorometer arrangement including at least one laser light source, particularly for use in measuring the luminescence in the course of a qualitative and quantitative determination of a sample material, the region of which to be excited is arranged in the object point of an emission monochromator and spectrograph, respectively, a holographic grating of said monochromator being provided with a central opening for passage of the exciting laser beam, and beam directing means are provided outside of the plane of symmetry of said emission monochromator and spectrograph, respectively.
