Title: Innovations of Robert J Delmer in Irrigation Technology
Introduction
Robert J Delmer is an accomplished inventor based in Huntington Beach, CA (US). He holds a total of 4 patents that showcase his innovative contributions to irrigation technology. His work primarily focuses on developing methods and devices that enhance the efficiency of water usage in 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 innovative design ensures a nearly constant drip-flow irrigation rate to plants, even as water pressure decreases along the length of the hose.
