Latest Patents
One of his latest patents is titled "Apparatus and process for continuous surface treatments of propellant." This invention relates to continuous triturators and malaxators featuring a horizontal drive shaft. The apparatus includes a semi-circular chute with vertical walls and a stirrer that has a concentric shaft carrying rigid blades. Notably, at least one in four blades is extended by a tongue that rubs against the chute, ensuring effective treatment of granular propellant powders. The materials used in the apparatus are conductors of electricity, enhancing its functionality.
Another significant patent by Cartier is the "Process for the purification of polycarbonates." This process effectively reduces the free and bonded residual phenol content in oligocarbonates produced through transesterification. By introducing water into the oligocarbonate at elevated temperatures under reduced pressure and purging the mixture with an inert gas, the process achieves substantial degassing. The resulting purified oligocarbonates exhibit remarkable resistance to yellowing, making them valuable in various applications.
