Abstract

The present invention relates to a system for determining a measure for an absorption of a sample. Such a system has an excitation radiation source, a sample holder, a detection device, and an evaluation device. During operation of the system, the excitation radiation source generates and emits electromagnetic excitation radiation having an excitation wavelength. In addition, it periodically modulates the excitation wavelength within a spectral tuning range during operation of the system. A sample can be received on the sample holder and, during operation of the system, the excitation radiation illuminates the sample received on the sample holder. The detection device detects periodic heating and cooling generated by the absorption of the excitation radiation in the sample, generates a detection signal which represents the periodic heating and cooling, and outputs said detection signal. The evaluation device is operatively connected to the detection device in such a way that the evaluation device receives the detection signal from the detection device during operation of the system, wherein the evaluation device is designed in such a way that it determines the measure for the absorption of the sample from the detection signal during operation of the system. According to the invention, the system has a filter gas cell in addition to the sample holder. The filter gas cell is arranged in a beam path of the excitation radiation between the excitation radiation source and the sample holder. A filter gas having a spectral absorption range is received in the filter gas cell, wherein the spectral absorption range and the spectral tuning range of the excitation radiation source overlap in such a way that the modulation of the excitation wavelength leads to an intensity modulation of the excitation radiation behind the filter gas cell in a beam direction.

A device for optically imaging a scene (SZ) has at least one optical detector (S1) and an optical arrangement which is arranged in front of the optical detector (S1) and by means of which the scene (SZ) can be imaged in a focal plane (F) of the optical arrangement. The detector surface of the optical detector (S1) is arranged outside the focal plane (F), and the optical arrangement has an amplitude mask or phase mask (M) which enables improved algorithmic reconstruction of a sharp image of the scene (SZ) from a blurred image captured by the detector (S1). In the device, in an alternative an optically non-linear filter (N) is additionally arranged in the region of the focal plane (F) and, in the case of incident optical radiation with an intensity above a threshold intensity, changes its optical properties in such a way that it blocks or at least attenuates said radiation. By means of said device, an optical sensor system is realized which has an improved protective effect against interference radiation, in particular incident laser radiation, with virtually unchanged overall size.

The invention relates to a process for recycling at least one polyolefin containing impurities in which polymer-containing waste containing the at least one polyolefin is provided and the at least one polyolefin is selectively dissolved in at least one solvent. At least one precipitating agent is then added to the polyolefin solution, wherein before, during or after this addition a temperature of the mixture is established which leads to melting of a portion of the at least one polyolefin and to formation of a melt phase and a liquid phase having a higher proportion (based on the total polyolefin mass in the polyolefin solution), i.e. a higher mass, of polyolefin than the melt phase. This is followed by a mechanical separation of the melt phase from the liquid phase and a drying of the liquid phase and/or the melt phase to obtain a low-impurity polyolefin fraction, and a polyolefin fraction enriched with impurities, as solids.

Abstract

Polyamides are known for their very good mechanical properties, thermal stability and media resistance and are therefore used as an important technical plastic in many fields. The processing thereof to fibers via the melt spinning process or to filaments by extrusion constitutes an essential processing step in the textile industry and 3D printing. Like most plastics, polyamides are also readily combustible materials, and therefore their applicability in fire-sensitive areas is limited. It is therefore necessary for technical textiles to be rendered flame-retardant. A proven strategy for this purpose is the aftertreatment of the textiles in a coating or impregnation step in which the flame retardant is applied.
