Title: The Innovations of Roger A Comes
Introduction
Roger A Comes is an accomplished inventor based in Midlothian, Virginia. He holds two patents that showcase his contributions to the field of measurement and synthesis processes. His work has significant implications for both environmental monitoring and chemical manufacturing.
Latest Patents
One of Roger's latest patents is titled "Methods and apparatus for measuring sidestream smoke." This invention provides a system for continuously and instantaneously measuring sidestream smoke produced by test cigarettes. The design includes a hood assembly that fits over the ports of a conventional smoking machine. An exhaust system continuously draws the smoke through the hood, while a laser beam passes through the smoke before being sensed by a photodiode detector. The resulting electrical signal is used to calculate the extinction coefficient of the smoke for comparison purposes.
Another notable patent is the "Process for synthesis of carboxamides." This invention improves the synthesis process by reacting 3-p-menthyl halide with magnesium to form a Grignard reagent. The reagent is then reacted with hydrocarbyl isocyanate at low temperatures to produce N-hydrocarbyl-p-menthane-3-carboxamide. The resulting product comprises a mixture of geometric isomers, with a weight ratio of 3-p-menthyl to 3-p-neomenthyl that can reach up to 9:1 under optimal conditions.
