Title: Innovations by Lewis A. Medlar

Introduction

Lewis A. Medlar is an accomplished inventor based in Oreland, Pennsylvania. He has made significant contributions to the field of fluid control technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of fluid flow systems.

Latest Patents

One of Medlar's latest patents is for a fluid flow control valve with maximized noise reduction. This innovative valve design includes a perforated cage and a perforated closed-end tube that operate as two sequential stages of restriction and pressure drop for the fluid flowing through the valve. A movable plug works in conjunction with the cage to regulate the net amount of flow restriction, thereby controlling the pressure drop and fluid flow rate. The tube's perforations are specifically sized to redirect the maximum amount of first-stage noise back into the tube, which is lined with sound-absorbing material. This design minimizes the noise level that passes downstream of the valve.

Another notable patent by Medlar is a pressure transmitter with a simplified pressure sensing head. This device features a pair of flat barrier diaphragms and a central control diaphragm situated between them. The first chambers, located between one barrier diaphragm and the control diaphragm, are filled with an incompressible fill liquid, while the second chambers are filled with a different incompressible fill liquid. The fill liquids create a dome shape in the barrier diaphragms, eliminating the issue of 'oil canning.' The pressures of the fill liquids act on a minute displacement sensing element, producing an electrical output signal that reflects the difference between the pressures of the two fluids.
