Abstract: Method and sorting system for sorting out waste glass cullet with a higher content of iron oxide from a single-layer material stream of waste glass cullet. The material stream contains waste glass cullet with a higher and a lower content of iron oxide. The material stream is irradiated with visible light and the visible transmission light passing through the waste glass cullet is detected, the material stream is irradiated with infrared light in a frequency range of at least 1100-1200 nm and the infrared transmission light passing through the waste glass cullet is detected, a waste glass cullet is classified as having a higher content of iron oxide if the ratio of the intensity of the infrared transmission light to the intensity of the visible transmission light exceeds or falls below a predetermined threshold value, and the cullet classified in this way is separated from other waste glass cullet.

Abstract: Crawled vehicle for the preparation of ski pistes; the crawled vehicle comprising a frame; two wheels assemblies displaced at opposite side with respect to the frame; two crawls, each of them wounded respectively around to one of the two wheels assemblies; and at least one supporting device, for each wheels assemblies, coupled to at least two wheels of the wheel assembly and connected in an articulated jointed manner to the frame for coupling the at least two wheels of the wheels assembly to the frame; wherein the supporting device has a first supporting element, which supports one of the at least two wheels of the wheels assembly; and a second supporting element, which supports another of the two wheels of the wheels assembly; and wherein the first supporting element and the second supporting element are connected to one another through a first articulated joint in a first point.

Abstract: The invention relates to a method and an apparatus for detecting leaded pieces of glass in a single-layer material flow of objects composed predominantly of waste glass, with the objects being irradiated with substantially monochromatic UV light (3) and the fluorescent light resulting therefrom being detected. It is provided therein that the object is additionally irradiated with visible or infrared light (4); the transmission light of the visible or infrared light (4) is detected after the passage through the object; and an object is defined as containing lead if both the fluorescent light for at least one predetermined wavelength range corresponding to the fluorescence of leaded glasses is present in a predetermined intensity range and also transmission light in a predetermined intensity range with an intensity of larger zero.
