Title: The Innovative Contributions of William A. Delmer
Introduction
William A. Delmer is a notable inventor based in Huntington Beach, California. He has made significant contributions to the field of irrigation technology, holding a total of seven patents. His work focuses on improving the efficiency and effectiveness of irrigation systems, which is crucial for agricultural practices.
Latest Patents
One of Delmer's latest patents is a method of making constant flow irrigation tape. This innovative drip irrigation tape hose features a primary flow path that communicates water along its length. Additionally, a secondary drip-flow path leads from the primary flow path to an emitter site located outwardly of the hose. The design includes a pair of variably spaced apart walls, with at least one wall formed with a continuously-open channel that defines part of the secondary flow path. The variable-area part of the secondary flow path is determined by the radial spacing of the walls. Notably, one of the walls responds to internal water pressure in the primary flow path, allowing it to open and close the variable-area part of the secondary flow path in response to changes in water pressure. This design ensures that the hose can provide a nearly constant drip-flow irrigation rate to plants, even as the water pressure decreases along the length of the hose.
