Latest Patents

Douglas R Powell holds a patent for an apparatus and methods aimed at liquefying and storing gas. This invention enhances the safety and efficiency of producing liquid oxygen using a small-scale liquefaction device. The patent describes a system where a switch is electrically coupled to a storage dewar pressurizing means. This switch is activated by a portable dewar when it engages with the storage dewar. Additionally, the system includes a cryocooler and/or cooling fan that enters a low power mode when the dewar liquid level reaches a predetermined level. It returns to full power mode when the liquid level drops below another set point. A cold finger of the cryocooler extends within the dewar to prevent overfilling, maintaining a temperature gradient that ensures the gas liquefies effectively.
