摘要： In a method and a device for identifying foreign bodies in a base textile material, the base textile material is subjected to beams and the beams reflected on the base material are detected and converted into an electrical signal. In order to detect foreign bodies in the material in a targeted manner and to differentiate them from each other, so all or only the unwanted foreign bodies can be, for example, eliminated, the beams have two defined and different wavelength ranges and the reflected beams are simultaneously and jointly detected from the two wavelength ranges. Preferably, a first defined wavelength range can be selected in such a way that the beams reflected on the base material provide random values in the electrical signal, for at least two different foreign bodies, and another defined wavelength range for the beams is selected in such a way that the reflected beams provide an electrical signal for the two foreign bodies, in a different ratio from the first wavelength range. The device contains a radiation source for radiation in at least two wavelength ranges, and a receiver for measuring the beams which are fully reflected by the material.

摘要： The invention relates to a method and a device for detecting foreign matter in a fibre composite moving in the longitudinal direction and consisting substantially of wool or cotton fibres. To provide an improved, easier and rapid method of detecting polypropylene in fibres intended for textile products the fibre composite is irradiated with infrared light (2, 3) in a defined wavelength range, the reflected light filtered (13) and the filtered fraction of the light measured (11). Values which significantly deviate from a base value indicate the presence of foreign matter.

摘要： A device for registering parameters of an elongated test material that takes up little space, can be manufactured easily and is cost-effective includes a light source for illuminating at least one region of the test material. The light source is in the form of a radiator of planar construction which is preferably designed for the emission of diffuse light. The radiator is connected to an electrode that is transparent and that can be applied to the radiator in the form of a layer.

摘要： To test a bottle for contamination, the bottom of the bottle is laterally illuminated with a measuring light beam from a source. This measuring light beam is deflected, as if in a waveguide, in the ring of residual liquids at the bottom of the bottle. Light reemerging from the residual liquid is imaged on a detector by an imaging lens. The detector measures the spectral composition of the deflected light and compares this with theoretical values which should be yielded by the liquid with which the bottle was last filled. If deviations from the theoretical values are excessive, the bottle is rejected. The process described provides a simple way of determining whether a multi-trip bottle has contained an extraneous liquid.
