A high speed granule delivery system and method is disclosed for dispensing granules in intermittent patterns onto a moving asphalt coated strip in the manufacture of roofing shingles. The system includes a granule hopper and a rotationally indexable pocket wheel having an alternating series of pockets and lands formed into the circumference thereof, and which is positioned adjacent a nozzle in the bottom of the hopper. Upper and lower side portions of the pocket wheel define and are exposed to upper and lower extents of a store of granules. A seal on the bottom of the lower extent of the store of granules seals against the raised lands as the wheel is indexed. In use, the pockets of the pocket wheel drive through and are filled with granules in the store of granules. As each pocket is indexed beyond the seal, it is exposed to the moving asphalt coated strip below and its granules fall onto the strip to be embedded in the hot tacky asphalt.

A multiple step coating process for coating a construction element having side portions, one of which is an unmasked transport side portion, and whereby at least three sides portions are coated, comprising: (A) advancing the element past a vacuum coater first coating station on the unmasked transport side wherein a surface layer is applied onto one or more of the non transport side portions of the element; and (B) subsequently advancing said coated element into further vacuum coater coating stations wherein a surface layer to the unmasked transport side of (A) and/or one or more of the remaining sides of the element.

Embodiments relate to surface treating a substrate, spraying precursor onto the substrate using supercritical carrier fluid, and post-treating the substrate sprayed with the precursor to form a layer with nanometer thickness of material on the substrate. A spraying assembly for spraying the precursor includes one or more spraying modules and one or more radical injectors at one or more sides of the spraying module. A differential spread mechanism is provided between the spraying module and the radical injectors to inject spread gas that isolates the sprayed precursor and radicals generated by the radical injectors. As relative movement between the substrate and the spraying assembly is made, portions of the substrate is exposed to first radicals, sprayed with precursors either one of the spraying modules or both spraying modules using supercritical carrier fluid, and then exposed to second radicals again.
