Apple, developer of modern innovations such as the iPhone, iPod, and Macbook, has submitted a patent application for a vaporizer.
The application is titled simply “Sublimator/Vaporizer” and describes a device that allows for the vaporization of an unidentified substance via a dual-chamber system. The abstract says, “A chamber body is to receive therein a substance that is to be vaporized or sublimated into a vapor. A plate whose bottom face rests on the substance inside the chamber body is temperature regulated, e.g., using a heater therein, which releases heat directly above the substance that lies below. The plate slides downward as the substance is consumed by vaporization or sublimation.”
The device described in the application is cylindrical in shape, including a thermal jacket and a body unit as well as a lid.
