  • Patent number: 9658039
    Abstract: Embodiments disclosed herein provide an Explosive Device Simulator (EDS). Embodiments of the Explosive Device Simulator may include two or more chemical components that are non-explosive when separated from each other within the EDS, but which form an explosive mixture or substance when combined. Because the individual chemical components are non-explosive, the Explosive Device Simulator may be stored, transported and handled safely for long periods of time and without increased security, protective measures, or special training. Further, the chemical components may be chosen such that the Explosive Device Simulator creates a realistic explosion (e.g. loud and bright), but which produces minimal concussive forces and is therefore safer to use as a training aid.

  • Patent number: 9586308
    Abstract: The present invention relates to a coated abrasive article containing abrasive agglomerates based on target cores that provide an extended surface. Target cores are defined as geometric shapes, e.g., spherical, rectangular, tetrahedral, conical, cylindrical, pyramidal or combinations and mixtures thereof. The preferred cores are porous structures with their own abrasive capacity as a grinding aid element. They are bonded on substrates, e.g., textile fabrics, plastic films, saturated or no treated papers, vulcanized fibers, non-wovens and mixtures thereof to produce extended surfaces on which are deposited the working abrasive particles, e.g., aluminum oxide, silicon carbide, zirconia alumina, ceramic aluminum oxide and mixtures thereof, through an electrostatic field to improve performance capabilities. The electrostatic field promotes orientation of the deposited grains around the cores with exposed sharp edges over the extended area, causing as a secondary effect the compacting of the abrasive grains.
