Abstract: A method of forming a wear-resistant reinforcing coating on a substrate, such as concrete, wood, metal or particulate. A reinforcing fiber mat is placed on the substrate and a liquid matrix material is mixed with small colored stones. The mixture of matrix material and stones is poured onto the mat, and the liquid wets the mat and contacts the substrate. After curing, a composite coating is formed with stones as the wearing surface. A membrane can be interposed between the substrate and the reinforcing coating to prevent adhesion and “starving” of the mat.

Abstract: A workstation for sealing the spar of an aircraft. A robotic arm can be positioned on a platform with a sealant application system. The platform can be moved along a path adjacent the spar to move the robotic arm. The robotic arm can move the applicator of a sealant applying system to a portion of a spar that is to be sealed. The sealant system can be positioned on the platform to be moveable along the path. The robotic arm can be moveable relative to the platform. The path can be positioned overhead of the spar. The spar can be rotated by a rotating fixture so that the platform can be moved in opposite directions relative to the path. A controller can control the movement of the platform along the path, movement of the robotic arm relative to the platform, movement of the applicator by the robotic arm, and the application of sealant by the sealant applying system.

Abstract: A method of forming a coating on an inner periphery of a tube with a cylindrical barrel, a mouth on one axial end of the barrel, and a shoulder located between the barrel and the mouth. The method involves holding the tube, and subsequently jetting powder into the tube from a spray gun, through a bottom side opening on the other axial end of said barrel. A first passage guides to the spray gun a first air stream together with the powder. A second passage feeds to the spray gun a second air stream with the powder. A third passage suction collects surplus powder through the tube mouth. A fourth passage suction collects surplus powder through the bottom side opening of the tube. At least one of the passages is subject to a feedback control such that flow rate and/or internal pressure therein are maintained at target levels.

Abstract: A fire resistant, self-adhesive rolled roofing membrane is used on low sloped roofs for insulating a surface from weather. The roofing membrane includes an asphalt-saturated fibrous material having a roofing surface area, for example, roofing granules on a portion of the top surface and a clean surface area on another portion of the top surface. The roofing membrane includes an adhesive surface area on a portion of the bottom surface opposite the roofing surface area and a parting agent covered surface area on another portion of the bottom surface generally opposite the clean surface area to prevent adhering to the clean surface area when rolled. The adhesive surface area includes a layer of self-adhesive material, such as rubberized asphalt, capable of adhering to the clean surface area when strips of the roofing membrane are overlapped. The adhesive surface area is covered with a release backing to prevent adherence to the roofing surface area.
