Patent number: 10627308Abstract: A wind tunnel device defines a cyclical tunnel to receive continuous airflow. Airflow is delivered through the tunnel to a testing region that includes a first portion carrying an arm including a spray tip configured to spray particulates in the testing region at an angle, and a second portion including an enlarged cutout region configured to receive the angled sprayed particulates. As airflow carries the angled spray particulates into the second portion, the enlarged cutout region enables the spray particulates to pass through and exit the second portion of the testing region. Analysis in the second region may be conducted through transparent walls free of openings to minimize exposure of the spray particulates to the exterior of the device. A scrubber is adapted to extract spray mist from the airflow as the airflow exits the testing region and is re-circulated through the cyclical tunnel.Type: GrantFiled: September 20, 2018Date of Patent: April 21, 2020Assignee: WINFIELD SOLUTIONS, LLCInventors: Eric P. Spandl, Jon Martin Gehring, Gregory Keith Dahl, Joe V. Gednalske, William Thomas Hambleton, Lillian C. Magidow

Publication number: 20160360744Abstract: Disclosed herein are methods of applying agricultural compositions including a pesticide, a fertilizer, or a combination of two or more of these, and about 0.1% v/v to 1.0% v/v of an adjuvant composition. The methods provide for aerial application of the agricultural compositions at wind speeds of up to 170 mph without substantially increasing the number of driftable droplets dispensed compared to the number of driftable droplets dispensed by applying the agricultural compositions without the adjuvant.Type: ApplicationFiled: June 12, 2015Publication date: December 15, 2016Inventors: Lillian C. Magidow, Joe V. Gednalske, Gregory Keith Dahl, Eric P. Spandl, Anthony Goede
