Abstract: It is described a system and method to monitor railway wheels, which includes obtaining images of the railway wheel by means of stereo cameras and performing a three-dimensional and two-dimensional model of the railway wheel by means of these images. This two-dimensional model is subjected to analysis of the profile of the railway wheel, comparing it with a two-dimensional model of an ideal wheel and thus measuring the effective wear of its profile. The three-dimensional model is subjected to analysis of the surface of the railway wheel, also comparing it with a three-dimensional model of an ideal wheel and thus measuring the effective wear of its surface.

Abstract: A system and method for automated control of reclaimers includes a boom, a bucket wheel, and a translation system. This system comprises memorizing operating parameters used during a turning movement of the boom, allowing identification of positions where there was an overflow or an unsatisfactory reclaiming flow. With this memorized information, the flow controller makes changes to the boom turning speed (Vg), increasing it in positions where the reclaiming flow was low and decreasing it in positions where there was overflow.

Abstract: Industrial demand for hexafluorosilicic acid (H2SiF6) is often lower than the amount produced from fluoride recycling processes. One alternative for using this surplus is manufacturing a soil conditioner by neutralizing the hexafluorosilicic acid with calcium oxide (CaO) inside an open, Kullman type reactor. The reaction ensures alkalinity to the soil conditioner having a pH of about 10, moisture less than about 40%, phosphorus (P2O5) at about 2.5%, calcium at about 22%, about 0.5% magnesium, about 10% silicon (about 30% to 40% water-soluble), about 18% fluoride, neutralization power of about 5% to 15%, and total neutralization power of about 5% to 12%. The resulting product, called AgroSiCa, is easily manageable with very high contents of Ca and Si (total and soluble), and also contains Mg, P, Fe, Zn, and F. When applied to soil, it contributes to the supply of nutrients, provides a better root growth and improves the plants development.

Abstract: An apparatus for airborne electromagnetic surveying is provided, comprising a central hub defining an equatorial plane, a transmitter loop, and radials connecting the hub to the transmitter loop. The loop generally lies in a plane during flight, and comprises loop sections, some of which are connected with flexible joints allowing the loop to flex out of the plane during lift-offs and landings. A loop section comprises current conducting elements connected to current conducting elements of adjacent loop sections forming a transmitter loop circuit. A radial connects to the hub at a point that is substantially offset from the transmitter loop plane, thereby contributing to the stability of the transmitter loop connection point in an up-down direction relative to the hub. Additionally, a loop section comprising rigid conductive elements retained in a spaced-apart relationship by a frame member is also provided.
