Provided is a seamless composite roofing system for a gravel built up surface. The system includes a first fluid application flood coat of bentonite emulsion applied over a gravel built up surface at a rate of 15 gallons per 100 square feet and a second fluid application flood coat of bentonite emulsion applied at a rate of 10 gallons per 100 square feet. The second flood coat includes approximately 3 to 6 pounds of chopped reinforced fiberglass per 100 square feet, and is applied over the first flood coat after the first flood coat cures. A fiberglass reinforcement layer with approximately 3 to 6 pounds chopped reinforced fiberglass per 100 square feet is applied over an area surrounding any roof top penetrations, followed by an elastic trowel grade mastic layer. An asphalt primer is then applied over the second flood coat, followed by a reflective Energy Star Rated top coat.

A method and system provide for reducing gaps between two mating parts. Either or both parts may be nondestructively inspected at a plurality of locations on a surface to gather a data set relating to the part thickness. The data set may be used to calculate a set of as-built thickness values for the part and a set of deviations from a design model. A mating area may be determined for mating surfaces of the parts. One or more layers of sacrificial material in the mating area may be prepared for any deviations greater than a design allowance. The system may include a ply cutting device and an additive manufacturing device coupled to a computer to receive the sacrificial material layer data and shim data and to cut the one or more layers of sacrificial material and to construct the shim. A shim may be constructed for any deviations equal to or greater than a minimum shim thickness. The one or more layers of sacrificial material may be applied to the part, cured, and machined to a desired thickness. The shim may be applied between the part surfaces. The parts may be fitted and assembled together.

A repair method for a civil engineering work. The method includes the depositing, directly onto a portion of the work to be repaired, of a reinforcing structure formed from one or more successive layers of at least one reinforcing material which are each extruded in contact with the surface onto which the material is to be deposited, using a robot system, with the material being extruded in strips.

A compressor unit (38) for supplying pressurized medium to a tire mounted on a vehicle wheel rim (34), having a compressor (58) for exerting pressure on a fluid medium that is to be conveyed into the tire. The compressor unit (38) is dimensioned to be accommodated in a center bore (44) of the vehicle wheel rim (34) when the vehicle wheel rim (34) is in the mounted state on a wheel hub (62); and the compressor (58) can be driven by a drive unit (56) positioned in the vicinity of the center bore (44) of the vehicle wheel rim (34). The compressor unit (38) is usable with a vehicle wheel rim (34) having a pressurized medium supply device (22) for a tire that is mounted on the vehicle wheel rim (34), as well as a vehicle having a vehicle wheel that includes such a vehicle wheel rim (34).

A glazing panel repair device (1) has coupling means (27) for coupling a pump arrangement (22) to the device to provide holding suction to secure the device to the glazing panel and pressure cycling to a repair zone. In one embodiment, the coupling means is for coupling a single pump to provide holding suction to secure the device to the glazing panel and pressure cycling to a repair zone.

The invention relates to a method of repairing a blade (1) made of composite material, extending in a so-called axial direction (X), the said blade (1) comprising a root (2) and a blade (3), the axial end of which opposite the root (2) comprises an area to be repaired, the said blade (3) comprising an intrados (4) surface and an extrados (5) surface.

A conditioning agent (typically for use in repairing a flaw in a glazing panel) is contained in a sealed container which is itself disposed internally of a flexible outer walled container. Pressure applied to the outer flexible walled container can cause release of the conditioning agent from the internal conditioning agent container. The conditioning agent preparation may comprise a hygroscopic solvent (such as acetone) combined with one or more primer additives to prime the surface of the glazing panel for repair.

The present invention provides a repair resin composition for repairing breaks in a vehicle windscreen and curing units for curing the repair resin after it has been inserted into the break. The present invention also provides a method of repairing a vehicle windscreen, comprising inserting a resin into a repair zone, wherein the resin comprises a photoinitiator that activates when exposed to light of an activation wavelength, wherein the activation wavelength is between 370 nm and 425 nm, and curing the resin by emitting light including light within the activation wavelength range onto the repair zone.

A puncture repair liquid unit and a puncture repair kit each has an extraction cap and a container. The extraction cap has a first flow path, a second flow path, and a third flow path. The first flow path extends between a first inlet connectable to an external compressor device for generating compressed air and a first outlet opening in the container. The second flow path extends between a second inlet opening in the container and a second outlet for taking out a puncture repair liquid from the extraction cap to supply to a punctured tire to be repaired. The second inlet communicates with the first outlet via the space of the container. The third flow path communicates with the first and second flow paths outside the space of the container so that a portion of the compressed air in the first flow path flows into the second flow path.
