Title: The Innovative Contributions of Lawrence James Sanchez

Introduction

Lawrence James Sanchez is a notable inventor based in Ann Arbor, MI (US). He has made significant contributions to the field of environmental technology, particularly in the area of exhaust sampling. His work is crucial for understanding and mitigating the impact of vehicle emissions on the environment.

Latest Patents

Sanchez holds a patent for a "Raw proportional toxic sampler for sampling exhaust." This innovative device captures components of interest on a resin column from a sample of exhaust gas emitted by an operating vehicle. Makeup air is added to the residual exhaust gas flow exiting the resin column at a junction downstream. The makeup air flow rate is determined using a laminar flow element along with pressure and temperature gauges. The sample and makeup air are drawn together through a blower, with the flow rate calculated based on differential pressure across the blower and the temperature of the gas. The controller adjusts a proportional control valve in the makeup air line to regulate the sample flow rate, ensuring it is maintained at a predetermined proportion of the exhaust gas flow rate.
