Title: Innovations and Contributions of James F Maxwell

Introduction

James F Maxwell is a notable inventor based in Provo, UT (US), recognized for his significant contributions to technology and engineering. With a total of 10 patents to his name, Maxwell has made remarkable advancements in various fields, particularly in nuclear magnetic resonance (NMR) and centrifuge technology.

Latest Patents

One of Maxwell's latest patents is the Digital Q-Meter for continuous-wave NMR. This innovative method allows for continuous-wave NMR measurements of nuclear magnetization at high magnetic fields, exceeding 2.5 T, without the need for analog down-mixing. The system utilizes an FPGA to control a digital clock pulse, stimulating a resonant circuit and providing a reference signal. An algorithm is employed to determine the real portion of a resonant circuit signal near the Larmor frequency of the species of interest, using only two measurements of the waveform per cycle. The FPGA also automatically adjusts a variable capacitance to tune the resonant circuit to the Larmor frequency.

Another significant patent is the Continuous loading and unloading centrifuge. This system is designed for treating tar sand and involves a centrifuge that, under centrifugal force, creates a three-layer system of wet sand, water, and petroleum. In this process, solvent-treated tar sand and water interact to strip solvent-solubilized hydrocarbons from the wet sand layer, which are then passed through the water and into the petroleum layer. The hydrocarbons are subsequently skimmed from the hydrocarbon layer for recovery.
