Title: The Innovative Contributions of Donald E. Lovelace
Introduction
Donald E. Lovelace is a notable inventor based in Carson City, NV (US). He has made significant contributions to the field of irrigation technology, holding a total of 5 patents. His innovative designs have improved the efficiency and functionality of irrigation systems.
Latest Patents
One of Lovelace's latest patents is the pop-up gear driven sprinkler head. This invention features a gear driven sprinkler head with a pop-up spray nozzle powered by a water-flow motor. The nozzle can rotate incrementally through an adjustable arc, allowing it to irrigate a specific sector size. It also automatically reverses at the endpoints of the selected irrigated sector. The ability to interchange nozzles ensures matched precipitation rates for different sector sizes. This design addresses the issue of reduced throw distance at high rotational speeds, which is a common problem in prior art assemblies.
Another significant patent is the solenoid-operated pilot-actuated valve. This diaphragm-type valve is particularly useful for irrigation purposes and can also be applied in industrial settings where controlling large amounts of flow energy with a small control signal is necessary. The valve operates by establishing fluid pressure in a diaphragm chamber, which keeps the valve closed. When the solenoid is energized, it opens the bleed tube, allowing the diaphragm to move and the valve to open. This design includes a self-cleaning action in the annular passage, enhancing its reliability.
