Abstract: An inline edge-sealing apparatus and method for sealing the kerf surfaces of cut cellular PVC board includes a rotary saw with either a tandem sealing disc or with an integral elevated sealing surface that is dimensioned to provide precise interference with kerf surfaces for friction and heat to melt and seal the surfaces in an aesthetically desirable manner. A kerf splitter, such as a kerf splitting pin, rod or riving knife, may be provided following a saw blade with integral kerf-engaging surface to avoid disruption of the sealed surface when cut boards exit the saw blade teeth.

Abstract: A method of automatically advancing a polymer cut-board, such as cellular polyvinyl chloride, through a stationary, non-spinning sealing element having a rounded or cylindrical surface that contacts and compresses a cut edge of the board to provide a sealed skin surface to the cut edge.

Abstract: A polymer board with a cut edge is automatically advanced through a stationary, non-spinning sealing element that contacts and compresses the cut edge and provides a sealed and smooth surface to the cut edge.

Abstract: A weatherstrip with improved stackability has a rigid base portion including a planar surface and a flexible strip portion adhered over a corner of the base portion and extending outwardly at an angle to the planar surface of the base portion.

Abstract: A board anchor includes flat faces that are complementary to angled flat faces of grooves of boards between which the anchor is secured by a fastener that passes through a fastener aperture of the anchor and into an angled groove face of a board and into an underlying supporting structure beneath the board.

Abstract: A method of coating an extruded member includes advancing an extruded member through a coating die and applying an outer layer material on to the extruded member with the coating die while a floating support supports the extruded member and makes vertical adjustments to the extruded member to maintain a substantially constant thickness of the outer layer material.

Abstract: A polymer board with a cut edge is automatically advanced through a stationary, non-spinning sealing element that contacts and compresses the cut edge and provides a sealed and smooth surface to the cut edge.

Abstract: An alkyl-tin stabilizer composition is treated with a calcium compound to reduce the carboxylate content level of the stabilizer.

Abstract: This invention includes methods for cleaning and sterilizing tissue harvested for implant with shock waves by submerging the harvested tissue in a volume of fluid in a holding vessel including a shock wave applicator with a focal volume in the volume of fluid, and applying a pressure shock wave pulses to the harvested tissue from the shock wave applicator in sufficient amounts to eliminate biological contaminants in the harvested tissue.
