  • Patent number: 11105598
    Abstract: A self-glowing solid material comprises a man-made metal mixture containing at least one rare earth metal and an oxide of iron. The material is inducible by flame initiation to self-glow with yellow-to-red colors (577-to-700 nanometer wavelengths). A stealth tracer ammunition comprises a projectile body having a tip and a base, and a solid pellet disposed in the base. The pellet may be made from the above-mentioned self-glowing solid material or another suitable material. The pellet becomes incandescent as a result of being heated when the ammunition is fired. The incandescent pellet emits a glow observable only from behind when the ammunition travels downrange after being fired. An illuminant comprises a bimodal blend of a man-made metal mixture containing at least one rare earth metal and an oxide of iron. The bimodal blend is a blend of smaller-sized fragments and larger-sized pellets. The illuminant is capable of ignition and dispersion in response to ballistic energy to create illumination.

  • Patent number: 11104805
    Abstract: Highly saturated scarlet dye ink for a high-speed inkjet process and a method of preparing the highly saturated scarlet dye ink are disclosed. In particular, an ink composition according to the present invention includes a dye including a compound represented by Formula 1, and further includes, in addition to the dye, distilled water, a surfactant, and an additive. The ink composition develops a highly saturated scarlet color that is unable to be developed by existing inks for digital textile printing (DTP), and has high water solubility, excellent heat resistance, and light-fastness, and thus may be effectively used as dye and ink for a high-speed inkjet process.

  • Patent number: 11034617
    Abstract: The present invention relates to a novel cementitious product produced from steelworks slag additivation to obtain material having properties suitable for use in the partial or total clinker replacement for the production of different types of cement. The process, which is also object of this invention, aims to adapt the properties of steelworks slag, by means of thermochemical treatment, including and preferably, but not only, still in the liquid steelworks slag pot, taking advantage of the thermal input of steel processing, to form a greater amount of alite (essential compound to increase pozzolanicity), under controlled conditions. After additivation, preferably, but not exclusively, the additivated steelworks slag is subjected to quenching, comminution and concentration to stabilize the alite fraction, to release the present phases and to remove any excess contaminants, such as metallic iron.
