Publication number: 20220090784Abstract: Delivery mechanisms and distribution mechanisms are varied, adjusted, or modified based on a desired fuel application. Dimensions, flow rates, pressures, viscosities, temperatures, friction parameters, and combinations thereof may be varied, adjusted or modified. The fuel application may include a scrubber application. The scrubber application uses a delivery mechanism to deliver a wet or dry scrubbing agent at a low pressure to a distribution mechanism. The distribution mechanism distributes the scrubbing agent within the scrubbing chamber. The delivery mechanism is adjustable based on properties of a feedstock utilized to deliver the scrubbing agent, properties of a propellant, or properties of the scrubbing application. The distribution mechanism is adjustable based on desired distribution characteristics including shape, size, or velocity of drops, mists, or particles distributed.Type: ApplicationFiled: December 7, 2021Publication date: March 24, 2022Inventors: John Alvin Eastin, David Vu

Patent number: 10081805Abstract: Bio-regulators from a group of quaternary ammonium moieties modify a gene expression in a plant to induce enhanced growth and robustness. Such bio-regulator may be applied to seeds through coating or encapsulating, to plants through root drenching, spraying and dusting. Bio-regulators may be duel-acting; causing beneficial modification to gene expressions in desirable plants while modifying gene expression in undesirable plants, making them more susceptible to herbicides. Bio-regulators are Ester Compounds, BMIA Compounds or related salts, BMIA Compounds or related salts of those compounds.Type: GrantFiled: October 10, 2016Date of Patent: September 25, 2018Assignee: KamTec, LLCInventors: Henry Yokoyama, James H.

Patent number: 9820426Abstract: Systems, methods, and apparatuses for applying specially formulated spray materials. The feedstock for the spray materials includes one or more immiscible materials. To mix immiscible materials at low pressure, the materials are applied from separate inputs of a fixture to separate channels where they are permitted to flow to and spread over surfaces or edges at selected thicknesses. On the surfaces or edges the materials are each subject to flowing air that forms small particles or drops even though the materials may be viscous. The particles or drops are mixed together and may be applied to a combustion device or spray device or any other device utilizing the mixture.Type: GrantFiled: October 5, 2015Date of Patent: November 21, 2017Assignee: Kamterter Products, LLCInventors: John Alvin Eastin, David Vu
