Latest Patents

One of his latest patents is an automated propellant blending apparatus and method. This invention utilizes closely metered addition of countersolvent to a binder solution with propellant particles dispersed within. The system precisely controls binder precipitation and particle aggregation. A profile of binder precipitation versus countersolvent-solvent ratio is established empirically. This profile is then used in a computer algorithm to determine countersolvent addition parameters near the cloud point. This control is crucial for managing the transition of properties of the binder during agglomeration and finishing of the propellant composition particles. The system is designed to be remotely operated by computer, enhancing safety, reliability, and product properties while also increasing product output.
