Abstract: A fixed-wing unmanned aerial vehicle (UAV) includes a propeller gimbal operably coupled to the body of the UAV at the forward end and the propeller gimbal is configured to pivot the propeller about a gimbal pivot axis to change a propeller angle. A controller of the UAV may be configured to control an attitude of flight of the UAV by controlling operation of the motor, the propeller gimbal, and the control surface assembly. The controller may be further configured to determine in-flight trajectory modifications that may require high maneuverability via high angle-of-attack attitudes of flight that are implemented via the propeller gimbal and trajectories determined from a dynamics model of the fixed-wing UAV.

Abstract: An active chemistry capable of being combined with a carrier to produce a coating for fertilizer or other granular or compacted products, where the coating is capable of being applied at ambient temperature and is capable of reducing moisture adsorption and caking of the granular product. The active chemistry may be a functionalized polymer such as maleic anhydride/acid (from maleic anhydride), itaconic acid, diisobutylene, methacrylic acid, alkyl acrylates (i.e. butyl acrylate), hydroxyl ethyl methacrylate, 2-acrylamido-2-methyl propane sulfonic acid, 3-allyloxy-1,2-propanediol acrylic acid, acrylamide, or a combination thereof.

Abstract: A fertilizer coating that provides nutrients and/or biocatalysts, as well as added dust control and caking control. The fertilizer coating may comprise a carrier, one or more micronutrient dispersants, and one or more micronutrients. The carrier may be aqueous-based or oil based. The coating may further comprise one or more biocatalysts in an aqueous media.

Abstract: A method for improving the rheological properties of mineral slurry comprising adding a copolymeric dispersing agent to the slurry to disperse silicate minerals. Also disclosed is a method for flotating mineral slurry.

Abstract: A method of removing impurities from silicates or clays through selective flocculation. The method comprises mixing a chemical product with silicates or clays, where the chemical product comprises a copolymer of acrylic acid, acrylamide, or a combination of acrylic acid and acrylamide with at least one of the following monomers: hydroxyl ethyl methacrylate, 2-acrylamido-2-methyl propane sulfonic acid, and/or 3-allyloxy-1,2-propanediol, or a derivative thereof; allowing impurities to separate from the silicates or clays; and removing the impurities from the silicates or clays. The chemical product may further comprise tannic acid, where the active tannic acid to active polymer concentration is 1% to 25% tannic acid, or more particularly 1% to 5% tannic acid.
