Title: Innovations by John M Macdonald
Introduction
John M Macdonald is a notable inventor based in Santa Fe, NM (US). He has made significant contributions to the field of protective barrier technologies, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is focused on in-situ leak testing of glovebox, isolator, or containment unit gloves. This invention provides a test plug for in-situ testing a glove installed in a glovebox, utilizing a top plate and a base plate, along with a diametrically expandable sealing mechanism. This mechanism engages the base plate to expand when the distance between the top and bottom plates is reduced. An inlet valve on the top plate allows for the introduction of pressurized gas into the glove, while a pressure gauge monitors the interior glove pressure.
Another significant patent developed by Macdonald involves puncture detecting barrier materials. This method and apparatus enable continuous real-time monitoring of the integrity of protective barrier materials, particularly against toxic, radioactive, and biologically hazardous materials. The invention measures conductivity, resistivity, or capacitance between conductive layers in multilayer protective materials, with significant changes indicating a physical breach of the barrier.
