Abstract: A system (1) and method for the detection of wagon swing (6) are provided. Wagon swing is detected by specific sensors (5a, 5b, 5c, 5d) when a wagon (6) presents excessive swing when passing through a certain section of a railway track (2), in which such detection is made by measuring specific distances, advantageously disregarding an angle of attack of the wagon wheels (6) measured between an axis of such wheels and a horizontal plane on which railway tracks (2) are located.

Abstract: The present invention relates to a process for producing an aqueous suspension of precipitated calcium carbonate, an aqueous suspension of precipitated calcium carbonate obtainable by the process, a precipitated calcium carbonate obtainable by the process, a product comprising the precipitated calcium carbonate as well as the use of the natural ground calcium carbonate (NGCC) in a process for producing an aqueous suspension of precipitated calcium carbonate.

Abstract: A calcium carbonate-containing material and a process for preparing the inventive calcium carbonate-containing material, wherein a paint includes the inventive calcium carbonate-containing material, and to the use of the inventive calcium carbonate-containing material. The calcium carbonate-containing material is prepared from an avian eggshell, wherein the calcium carbonate-containing material has a weight-median particle size d50 of from 0.5 to 10 ?m, and/or a weight top cut particle size d98 of from 2.0 to 40 ?m, and wherein the calcium carbonate-containing material includes organic matter in an amount of below 1.5 wt. %, based on the total dry weight of the calcium carbonate-containing material, and wherein the calcium carbonate-containing material has i) a brightness from 90 to 100%, according to R457, and/or ii) L* from 95 to 100, according to DIN 6174.

Abstract: The present invention refers to a process for producing nano precipitated calcium carbonate (nano-PCC), as well as to the nano precipitated calcium carbonate (nano-PCC) obtained by such a process and a system for producing the nano precipitated calcium carbonate (nano-PCC) comprising at least one dry mill, preferably a dry sandmill. Furthermore, the present invention refers to the use of the nano precipitated calcium carbonate (nano-PCC) as well as to the use of the inventive system for producing nano precipitated calcium carbonate (nano-PCC).

Abstract: The present invention relates to a process for the preparation of precipitated calcium carbonate allowing for a more sustainable and cost-efficient use of milk of lime. The obtainable products show good optical properties as well as fine particle size distributions.
