Title: Innovations by Donald E Garfield

Introduction

Donald E Garfield is a notable inventor based in Meriden, NH (US). He has made significant contributions to the field of technology with a total of 2 patents. His work primarily focuses on measuring groundwater flow and adhesive bond strength, showcasing his expertise in engineering and environmental science.

Latest Patents

One of Garfield's latest patents is a groundwater flow measuring system. This innovative probe is designed to monitor groundwater flow seepage velocity and direction. It features an electrical heater and multiple temperature sensors positioned equidistant from the heater. The probe is lowered into a monitoring well, where it is immersed in groundwater. By sending energy to the heater and measuring the temperature response at the sensors, the system computes and records the groundwater flow velocity and direction. The temperature sensors can be resistance temperature detectors, thermocouples, or other advanced temperature sensing devices.

Another significant patent by Garfield is an apparatus and method for measuring adhesive bond strength. This improved apparatus includes a short, cylindrical specimen attached to a rigid base, which allows for movement along tracks. A rigid mold block is supported above the specimen, and the adhesive bond strength between two materials is determined by applying a shear force to the bond. The force and deformation at which the adhesive bond fails are measured, providing valuable data for material science.
