Title: The Innovative Contributions of David P Ward

Introduction

David P Ward is a notable inventor based in Dallas, TX, with a remarkable portfolio of nine patents. His work primarily focuses on advancements in agricultural technology, particularly in the handling and application of anhydrous ammonia.

Latest Patents

Among his latest innovations is the "Anhydrous Ammonia Vapor Charge Unit for an Applicator Tank." This invention maintains a pressure charge on an applicator tank by utilizing a secondary anhydrous ammonia tank positioned adjacent to the applicator tank. Ammonia vapor from the secondary tank is passed through a vapor compressor and injected into the applicator tank, enhancing the pressure charge. In a second embodiment, a portion of the liquid flow stream of ammonia is separated, passed through a heat vaporizer, and then injected into the applicator tank to maintain the pressure charge. The heat vaporizer preferably uses hydraulic fluid from a tractor to heat the anhydrous ammonia.

Another significant patent is the "Anhydrous Ammonia Flow Dividing Manifold." This device divides a flow of anhydrous ammonia, which contains both liquid and gas phases, into separate flow paths. The manifold features a first mixing nozzle that concentrates the flow in one direction against an enclosed end of a mixing chamber, while a second mixing nozzle directs the flow orthogonally against another enclosed end of a second mixing chamber. A flow divider structure is positioned around the second mixing chamber, featuring multiple flow ports that are angularly spaced and extend orthogonal to the second flow direction.
