Cut gemstone providing a specific optical pattern

Abstract: A gemstone cut with a table facet, where the gemstone receives existing light from around the viewer and the facets on the bottom of the diamond effectively reflect the existing light back into the eyes of the beholder in such a manner as to maximize light performance, and to produce a unique and distinct look of light in the form of a flower with eight rounded pedals under the table facet which can be observed in natural ambient light.

Feedstock particle size distribution and water content dynamic in a pellet mill production process and comparative sieving performance of horizontal 3.15-mm mesh and 3.15-mm hole sieves

Abstract: Pellet feedstock particle size distribution is the main factor affecting pellet quality. Feedstock samples were obtained from different places in the production process of a commercial pellet mill. Particle size distribution and water content of the sieved particle fractions were analyzed. The results showed an alternation of particle size distribution and water content of the feedstock induced by the processing in the mill. Storage had a balancing effect on the water content distribution between the different particle size classes. Further experiments evaluated the reason for the underrepresentation of the 2.8–3.15-mm fraction in the feedstock. It was found that the major sieving factor for non-spherical wood particles was their width rather than their length, though the aspect ratio was important for the sorting between the 2.8–3.15-mm and the 2.0–2.8-mm sieve fractions. The significant differences between the particle width in the sieve fractions and the distribution of the particle aspect ratio improved when using a 3.15-mm mesh sieve instead of the 3.15-mm hole sieve. This indicates the better sieving performance of the 3.15-mm mesh sieve, which should be considered by pellet manufacturers and researchers investigating pellet feedstock.

Apparatus for feeding inserts into a mould of a press casting machine or a die casting machine

Abstract: of EP0823299Equipment for continuously feeding and locating inserts (9) in a moulding tool (5) or tool insert of a pressure die casting or injection moulding machine comprises a feed channel (15) close to the tool for holding and guiding inserts and a mechanism (17,18) for accurate positioning of an insert taken from the feed channel.
