Title: John S Haglund: Innovator in Aerosol Concentration Technology

Introduction

John S Haglund is a notable inventor based in College Station, TX (US). He has made significant contributions to the field of aerosol technology, particularly with his innovative patent that enhances the concentration of aerosols.

Latest Patents

Haglund holds a patent for a "Circumferential slot virtual impactor for concentrating aerosols." This invention features a disk-shaped housing with an endless circumferential slot designed to receive aerosols. The slot functions as an acceleration nozzle, while a receiver nozzle is positioned radially inward from the acceleration nozzle exit. In the annular gap between these nozzles, negative pressure is selectively applied to draw a major flow of the aerosol axially away from the nozzles. Simultaneously, a minor flow of the aerosol is drawn radially inward into the receiver nozzle. This design allows a portion of the larger particles to leave the major flow and merge with the minor flow due to particle momentum, thereby increasing the concentration of larger particles in the minor flow. The acceleration nozzle is designed with convex curvature along its opposed interior surfaces, which facilitates smoother aerosol flow and reduces large-particle deposition.
