A lighting apparatus for use with line scan cameras in plants for detecting and recognizing objects in a flow of materials such as goods to be sorted, in which several separately controllable diodes and an optical device are provided, with the diodes being disposed at least in one row next to one another over the width of the respective section of the plant and the optical device regularizes the light emitted by the diodes in such a way that a secure detection of the objects and its properties such as material composition, color, size or the like is ensured by cameras. The optical device comprises two diffusers and an interposed lens.

Method and apparatus for sorting waste paper pieces of different grades and conditions. The method includes moving a plurality of waste paper pieces in a conveying direction on at least one sorting belt, each waste paper piece having a surface, irradiating at least one area of the surface with radiation, registering the radiation reflected from the surface, and sorting the waste paper on the basis of the reflected radiation, wherein waste paper pieces of at least one type are separated from waste paper pieces of at least one other type. The apparatus includes at least one sorting belt for conveying a plurality of waste paper pieces in a conveying direction, at least one radiation source arranged above the sorting belt for irradiating at least one area of the sorting belt, at least one evaluation device which registers the radiation reflected from the pieces of waste paper, and at least one sorting device arranged downstream from the at least one radiation source, wherein waste paper pieces of at least one type are separated from waste paper pieces of at least one other type using the at least one sorting device and on the basis of outputs from the evaluation device.

Method to determine the purity of treated used glass, whereby the sample quantity is taken from the treated used glass and arranged in one layer and is sent trickling down a free-falling path, the foreign bodies according to non-ferrous metals and opaque foreign materials being blown out and weighed after a separate identification, and the ratios of non-ferrous metal additions to the whole sample quantity and of the opaque foreign materials to the whole sample quantity respectively being determined. In order to be able to carry out such a method in a particularly simple manner, it is provided that the foreign materials are continuously weighed together, and depending on which kind of foreign materials--non-ferrous metals or opaque foreign materials--has been identified, the increase in weight is attributed to this identified group.

Method to determine the purity of treated used glass

An apparatus for sorting pieces of waste of materials having different properties comprises a disk revolving about a substantially vertical axis and comprising a conically upwardly and outwardly tapering rim defining a conveying path, which is concave in cross section, the rim constituting an outer guide wall, and a feeding device for feeding successive pieces to the revolving conveying path at a feeding station. The revolution of the conveying path generates a centrifugal force holding the pieces against the outer guide wall, and a sensor device is arranged along the conveying path for sensing the different properties of the successive pieces. Devices controlled by the sensor device remove single pieces at discharge stations dependent on the sensed properties of the pieces.

Method and apparatus for sorting waste

A method for determining the purity of treated used glass, in which the sample quantity is taken from the treated used glass stream and the foreign bodies still contained therein, separated according to non-ferrous metals and opaque foreign materials such as ceramic and porcelain particles and stones, are sorted out, weighed and put in relation to the weight of the whole sample. In order to be able to analyze a sample in a simple manner, it is provided that the sample is piled in one layer and allowed to trickle over a free-falling path and that foreign bodies made from non-ferrous metals are blown out and thereafter opaque foreign bodies are blown out and collected in containers separate from the non-ferrous metals.
