Abstract: A cooler (1) for cooling hot bulk goods (17) preferably iron ore sinter: The cooler has a grate surface (16) for holding the hot bulk goods (17) to be treated to reduce the dust emissions and at the same time to also enable maintenance measures on the cooler (1). Covers are located in the region of the feed point (2) and the removal point (3). The device herein provides an additional boundary, which prevents the removal of dust particles of size over 150 ?m. The boundary is a stationary first wall (12) and a stationary second wall (11) and the boundary extends over a partial segment, and preferably over the entire region, of the uncovered grate surface (16). A supporting structure (18) is provided, to which the first wall (11) and the second wall (12) are fastened.

Abstract: A supply chute, and a system and a method for supplying sinter material from a sinter belt to a sinter cooler (26). A flow of the sinter material (16) is input into the supply chute (1). The flow of sinter material (16) after being input is concentrated by a device in the chute. This means that the flow is remixed for more uniform grain size distribution. The flow is thereafter widened by a widening device in the chute. Then the widened flow of sinter material (16), optionally after making the movement direction of the flow of sinter material (16) uniform, the flow is passed through a segregation device (8,25) and is there segregated, which means that a grain size distribution across the thickness and across the width of the flow is made more uniform. This occurs after the widened flow of sinter material moves in the direction of the output region (5).

Abstract: A cooling device (2; 50) for cooling bulk goods (4), which has a cooling shaft (8) and at least one supply chute (14) for introducing the bulk goods (4) into the cooling shaft (8). To achieve uniform cooling of the bulk goods (4), the supply chute (14) has a first wall (30) and a second wall (32) arranged opposite the first wall (30). At least part of the first wall (30) is arranged at a different angle of inclination (34) with respect to a vertical line (36) than the second wall (32).

Abstract: An organic photodetector detects infrared radiation, particularly radiation within the spectral region of over 1100 nm, the so-called imager region. Contrary to the currently known photodetectors, such as the Bolometer, II-VI semiconductor, and quantum well detectors, the photodetector contains semiconducting nano-particles for shifting the range of detection, requires no technical and cost-intensive effort in the production thereof, and may be constructed of flexible substrates by simple printing methods.
