Title: Innovations by Lester B Engelmann
Introduction
Lester B Engelmann is an accomplished inventor based in Woodland, CA (US). He has made significant contributions to the field of engineering, particularly in the area of backflow prevention technology. With a total of 3 patents to his name, Engelmann's work focuses on enhancing safety and efficiency in water systems.
Latest Patents
Engelmann's latest patents include a "Method and apparatus for automatic remote testing of backflow preventers." This innovative apparatus allows for the automatic and remote testing of check valves and backflow preventers. The system utilizes pressure sensors that communicate with chambers upstream and downstream from the check valve being tested. These sensors can be pressure transducers or pressure switches, designed to ensure accurate readings. The method confirms zero or substantially zero liquid flow through the check valve, utilizing either an existing water flow meter or an auxiliary water flow switch. The differential pressure between upstream and downstream is sampled and compared with predetermined standards, resulting in a pass/fail report that can be communicated to a remote facility.
Another notable patent is the "Apparatus and method for automatically disabling pressure relief valve." This invention focuses on the automatic disablement of a pressure relief valve used in conjunction with a backflow preventer in a fire line. The system includes a normally open solenoid valve in a pressure sampling line, which is actuated by a water flow switch. This mechanism ensures that even in the event of a check valve malfunction, the pressure relief valve remains closed, preventing catastrophic water pressure loss in the fire line.
