Patent DE-19816881-A1 (DE)
Title: Differentiating materials, colors and contaminants in granulated plastic scrap
Inventor: FEY DIRK
IPC: G01N21/89
Filed: 1998-04-17
Abstract: A line of the material (10) is laser-illuminated (5). Light returned is intercepted by the same optical system (2) and analyzed spectroscopically. The material is classified (13) in terms of basic materials and/or color and/or contaminants. It is separated. Preferred features: Illumination of materials and measurement of reemitted radiation is carried out in a system employing a mirror drum and torroidal hollow mirror constructed from individual segments. The spectrally-resolved light is measured by a multi-anode photomultiplier tube as a spectrum. To perform analysis, color identification and contaminant recognition is executed by signal processing, programmed logic, and by mathematical algorithms with calibration vectors. The signals are processed using multi-channel analog methods in accordance with mathematical models, summing all channel signal contents and classifying the sums. A processor carries out determinations from measured and reference spectra stored in memory. Mathematical classification models are employed.

Filed: 1999-02-09
Abstract: A device for determining the pressure between a contact wire and a pantograph of an electrically-powered vehicle is provided with a measuring device for the static pressure, which is determined based on the distance between two elastically interconnected components of the pantograph, this being dependant on the static pressure; and an acceleration sensor which is coupled with the pantograph in order to determine the accelerations of the pantograph in the direction of the pressure. The output signal of the acceleration sensor is combined with the output signal of the measuring device in order to calculate the pressure. The acceleration sensor is configured in such a way that it has a seismic mass (3) which is spring-mounted on the pantograph (6). The position of the seismic mass in relation to the pantograph is detected optically and a corresponding optical signal is then transmitted to an optoelectrical converter which is separate from the pantograph in terms of potential.
