    Abstract: PROBLEM TO BE SOLVED: To determine variation in the color of a molten plastic quickly and accurately by introducing a light through a light emitting duct and a sensor head to a molten molding material and transmitting the light reflected therefrom to a spectrometer through a light receiving duct. SOLUTION: Uncolored plastic granules 1 and granules 2 containing a large quantity of coloring agent are fed an extruder 4 having two shafts turning simultaneously at same speed while meshing tightly and heated up to a temperature higher than the melting point while being mixed uniformly. An extrusion molding is delivered to a catcher 5. At the end of the extruder 4 mixed with the free ends of a light emitting duct 7 and a light receiving duct 9, a sensor head 6 projects into the extruder 4 through screw engagement. The light emitting duct 7 is coupled with a light source 8 and the light receiving duct 9 is coupled with a spectrometer 10. Pulse from the spectrometer 10 is delivered to an analyzer 11.

    Abstract: The method involves subjecting the particles to electromagnetic radiation that is scattered on the particles, determining the intensity of the scattered radiation in at least two different scattering regions and setting them in relation to each other. One scattering region contains the forward scattering region and another the rearward scattering region. Independent claims are also included for the following: (1) an arrangement for determining collective physical parameters of particles in gases; (2) a use of the method for aerosols in gases; (3) a computer program for implementing the method; (4) a data medium with a computer program.

    Abstract: The disclosure is a probelike apparatus (16) for spectroscopic analysis of a fluid medium (19) by attenuated reflection. Two light beams from a light source (11) impinge upon the boundary (18) between a prism (17) and the medium (19) to be analyzed and the intensities of the light beams reflected at the boundary are measured in a detector unit (22). The two light beams differ in their angle of incidence on the boundary and/or in their polarization state. Measurement is preferably carried out under total reflection.

    Abstract: A process for the continuous colour measurement of plastic articles by means of a device (I) is new. Light is conducted via a transmitter optical fibre (II) and a sensor head (III) into the plastic melt and the reflected light is guided via a receiver optical fibre (IV) to a spectrometer or multi-range photometer (II) and (IV) are arranged such that they are the same distance apart from each other. Also claimed is (I).
