Title: Roderick I Guthrie: Innovator in Molten Metal Detection

Introduction

Roderick I Guthrie, an inventive mind hailing from Westmount, Canada, has made significant strides in the field of molten metal detection. With three patents to his name, his work focuses on advancing technology for the measurement of particulates in molten metals, contributing vital improvements to the metallurgy industry.

Latest Patents

Among his most notable patents, two inventions stand out: the "Apparatus for the Detection and Measurement of Particulates in Molten" and the "Method and Apparatus for the Detection and Measurement of Particulates." Both inventions provide a robust method for detecting non-conductive particulates in molten metals like aluminum, gallium, zinc, and lead.

Guthrie's latest patented apparatus utilizes a specialized passage of about 300 micrometers in diameter to create a current path between two electrodes carrying a current ranging from 1 to 500 amperes. This ingenious design allows liquid metal to form an effective Faraday cage, which screens the path. Particulates of 15 micrometers or larger can generate detectable voltage pulses between the electrodes—greater than 5 microvolts—rendering a swift evaluation of particle size distribution possible within less than three minutes. This rapid analysis enables operators to make immediate decisions regarding the necessity of further cleansing of the metal.
