    • Arc welding systems, methods, and apparatus that provide dual-spectrum, real-time viewable, enhanced user-discrimination between arc welding characteristics during an arc welding process. Welding headgear (110) is configured to shield a user from harmful radiation and to include a digital camera or cameras (150, 160) to provide dual-spectrum (i.e., both visible spectrum and infrared spectrum) real-time digital video image frames. The welding headgear (110) is also configured with an optical display assembly for displaying real-time digital video image frames to the user while wearing the headgear (110) during an arc welding process. Image processing is performed on the visible and infrared spectrum video image frames to generate dual-spectrum video image frames providing an integrated and optimized view of both the visible and thermal characteristics of the arc welding process which can be viewed by the user on the optical display assembly in real time.

    • A process for increasing a granular particle density of a polymeric product using at least one particle density promoting agent is described. The process includes passing a gaseous stream comprising at least one monomer through a fluidized bed reactor in the presence of at least one to form a polymeric product having a first granular particle density of less than or equal to about 850 kg/m 3 , contacting the polymeric product with at least one particle density promoting agent to increase the granular particle density of the polymeric product by at least 2 %, withdrawing the polymeric product having an increased granular particle density and a recycle stream comprised of unreacted monomers, and cooling and reintroducing the recycle stream into the fluidized bed reactor with sufficient additional monomer to replace the monomer polymerized and withdrawn as the polymeric product.
