| 20080203603 | METHOD OF FORMING COMPOSITE ARTICLES - A method for forming a composite article includes injecting first and second compositions into a die head at different points so as to produce a partially mixed composition that is discharged from the die head. The second composition contains less filler material than the first composition. | 08-28-2008 |
| 20090126307 | PLANKING SYSTEM AND METHOD - A novel planking system utilizing an inventive groove design is provided. The novel groove is defined by two opposing side walls and a groove end wall. The groove side walls present two generally opposed tongue-engaging projections that automatically provide a uniform space between planks during installation, and accommodate expansion of the planks after installation by breaking away when force is exerted on the projections by an adjacent plank. The present invention is also concerned with a combination of planks having an inventive tongue-and-groove configuration, as well as inventive methods of assembling planks to accommodate the expansion and contraction of the assembled planks after installation. | 05-21-2009 |
