The resultant extrudate exhibits reduced chatter, which is categorized according to the Reed Scale as less than or equal to 2.||02-02-2012|
|20100264644||FITTING FOR CORRUGATED CONDUIT - A fitting for joining a corrugated conduit to a structure associated therewith is disclosed. The fitting comprises a hollow body having an inner chamber and at least two body resilient tabs extending from an end. The at least two body resilient tabs define at least two body gaps therebetween. Each of the at least two body resilient tabs defines an outwardly extending detent. The fitting also comprises a retaining ring including a flange and at least two ring resilient tabs extending from the flange and defining ring gaps therebetween. Each of the at least two ring resilient tabs defines an inwardly extending detent adapted to engage a corrugated conduit. Each of the at least two body resilient tabs is selectively inserted in a corresponding one of the at least two ring gaps, and the outwardly extending detents selectively engage an end of the flange of the retaining ring.||10-21-2010|
|20090321973||Method Of Partially Engraving Foamed Plastic Extrusions - A method of only partially engraving foamed plastic extrusions and foamed plastic extrusions so engraved, the method comprising formulating the plastic to leave residual foaming agents after extrusion and contacting one or both sides of the extrusion with an embossed engraving roller or rollers controlled to limit penetration and contact of the foamed plastic with the outer portions only of the roller embossment to activate residual foaming agents to foam the plastic around such penetrating portions.||12-31-2009|
