  • PURIFICATION AND EXTRACTION OF CANNABINOIDS
    Publication number: 20210370198
    Abstract: A method for purification and extraction of cannabinoids includes: providing a cannabis oil including phospholipids and cannabinoid acids; contacting the cannabis oil with a degumming solvent, wherein the degumming solvent and cannabis oil are substantially immiscible; and separating an aqueous phase including the degumming solvent and at least a portion of the phospholipids from an oil phase including the cannabis oil. The method may further include contacting the oil phase with an extraction solvent, where the extraction solvent and oil phase are substantially immiscible; and separating an aqueous phase including the extraction solvent and at least a portion of the cannabinoid acids from a second oil solvent phase including the oil phase and/or simply the liberated cannabinoids following acidification of the extraction solvent.

  • Self-sealing fastener
    Patent number: 8869579
    Abstract: A fastener suitable for use in airplane manufacture or repair that is coated with a pre-mixed moisture cure sealant. The sealant layer is coated with a frangible moisture barrier that will break apart when the fastener is installed, thus exposing the sealant to atmospheric moisture. Once exposed to moisture, the sealant will begin to cure. Preferred embodiments also provide a moisture indicator that provides a visual indication that the outer moisture resistant layer has been damaged.
