Title: Innovations of Leo M Lester
Introduction
Leo M Lester is an accomplished inventor based in Medford, MA (US). He holds a total of four patents, showcasing his expertise in the field of valve technology. His innovative designs have contributed significantly to the efficiency and functionality of fluid control systems.
Latest Patents
One of his latest patents is the "Precise Throttling Ball Valve." This invention provides a ball valve designed for precise throttling of fluid through the valve. The valve features a housing with a fluid passageway and a valve seat positioned within it. A valve stem extends through the housing into the valve seat, connecting to a spherical valving member that is rotatably mounted. The valving member includes a passageway that is cylindrical at the upstream end and partly closed at the downstream end by a throttling wall. An oblong outlet extends through this wall, aligned orthogonally to the passageway and the rotational axis of the valve stem.
Another significant patent is the "Position Indicator Apparatus for Rising Stem Valve." This apparatus includes a switch with a rotatable post that connects to a power source and a signal. The switch is mounted in a fixed position relative to the valve housing. A connecting beam links the switch post to the valve stem, allowing the movement of the valve stem to rotate the switch post. This rotation completes or breaks the circuit to the signal based on the position of the valve stem.
