Abstract: In one embodiment, a concentrated solar power system includes a solar tower, multiple solar receivers mounted to the solar tower at different vertical elevations, and a plurality of heliostats provided on the ground within a heliostat field, wherein each heliostat is configured to concentrate solar radiation on any of the solar receivers mounted to the solar tower.

Abstract: The present invention discloses a heat transfer chain comprising circular links made from elliptical cross section solid wire, having a greater radius: lesser radius ratio of 1.5 to 3.0, having the axis formed by the greater radius of the elliptical section lined up with the diametrical direction of the circular link, achieving this way an increase in the chain's durability (less wear in time), and at the same time obtaining greater heat transfer efficiency due to a high surface area to unit of mass (ton) ratio in the installed chain. The present invention may be applied primarily to rotating chain furnaces, wherein these experiment transitory increases and reductions in temperature, for heat transfer between two or more phases, commonly seen in the concrete, paper and fertilizer industries.

Abstract: A device for sampling, diluting and analyzing particles and substances normally located on surfaces. The device includes a collection system which, through a rotating collecting surface and a scraper gathers the sample. The device also includes a tank-like storage system to store the diluting solution and a dilution chamber that permits the sample to mix with the solution and be diluted. This mixture is subsequently placed in contact with a detection system which is capable of discerning the presence or not of the substance being sampled.
