Abstract: Spray nozzles are aimed at openings in the side of capture chambers. Fluid is pumped directly from sumps within the capture chambers through the spray nozzles and into the capture chamber openings. Vegetation passing between the nozzles and the capture chambers is sprayed, and any fluid not intercepted by vegetation is returned to the sumps after entering the capture chamber openings. The fluid level in each sump is regulated by a float valve which interrupts a flow of fluid fed by gravity from a supply tank.

Abstract translation: 喷嘴针对捕获室侧面的开口。 流体从捕获室内的水槽直接通过喷嘴泵入捕获室开口。 在喷嘴和捕获室之间通过的植被被喷射，并且在进入捕获室开口之后，任何未被植被遮挡的流体返回到水池。 每个贮槽中的液位由浮阀调节，该浮阀中断从供应罐重力供给的流体流。
