Title: Daniel Mathieu and His Patent for Pressure Measurement in Pulsed Columns.

Introduction

Daniel Mathieu is an inventor associated with Avignon, France, and the Commissariat à l’Énergie Atomique et aux Énergies Alternatives. His patent concerns measuring pressure differences in a pulsed column, with an approach designed to reduce the effects of pressure fluctuations caused by pulsation.

Latest Patents

The available information identifies one patent associated with Mathieu: Device for Measuring a Pressure Difference Within a Pulsed Column. The device uses two dipping tubes that enter the column at separate points. Gas is introduced through each tube and bubbled into the liquid, while a measuring system determines the pressure difference between the tubes.

The tubes enter the column through cavities sized to keep the gas-liquid interfaces within those cavities during pressure changes caused by pulsation. The interface-level changes are inversely proportional to the densities of the liquids in the cavities, helping compensate for pressure variations within the liquid. The device can also be used to measure the interface level in a decanter. Mathieu is credited with 1 patent.

Career Highlights

Mathieu’s documented patent work addresses pressure control and measurement in pulsed-column equipment. The invention’s design focuses on reducing the influence of pulsation-related pressure changes, supporting more reliable measurements in the column.
