Sealing compositions and application methods for sealing and protecting asphalt roof shingles or other porous roofing and construction materials are described for eliminating algae, mold and mildew, increasing granular adhesion, providing additional UV protection and significantly increasing the wind resistance of the roof or other construction material. The sealing composition includes an acrylic polymer that has been modified by a silicone surfactant to alter its wetting properties so as to promote wicking of the sealer under asphalt shingles and at open edges to prevent curling and water infiltration. The method of applying the sealing composition promotes uniform distribution of the product on the surface of installed roofs as well as enhances bonding between individual shingles by improved penetration on and between shingle layers to increase adhesion area.

A rechargeable type callus removal instrument is disclosed, that includes a main body having a flaring tube shape with one side opened. The instrument can include a callus storage fitted around the motor shaft of an internal motor that rotates with rotation of the motor shaft, thereby collecting calluses separated from a user's foot therein. A filing cap can cover an upper surface of the callus storage for removing calluses on the user's foot while rotating with the callus storage in contact with a callus surface of the foot. A guide member can be included to assist with forming an exterior barrier such that the calluses being removed by the filing cap are collected in the callus storage without scattering about to the outside. The callus removal instrument enables callus removal using a rotational force of a motor through electric recharging with an improved portability while preventing water infiltration.

Disclosed is a roof assembly for a modular building unit that comprises a roofing sheet that is welded to the frame of the modular building unit to form a unitary, continuous sealed weld between the roofing sheet and the generally horizontal structural frame of the modular building unit, and that is pitched to downwardly direct water toward one end of the modular building unit. The welded roof assembly prevents water infiltration into the modular building unit, and such watertight structure may then receive any gutter configuration the user wishes to implement without risking water infiltration into the building unit. The welded roofing sheet avoids the use of screws or other fasteners, and the associated possibility of water leakage around the screws and into the building unit. The welded roof also is able to employ a single slope all of the way through the full span of the roof, thus avoiding the need for a centrally pitched roof assembly, and its unitary construction avoids the tiling effect that results from the use of multiple, overlapping roofing sheets. The welded roof also avoids the need for silicon or other filler agents between the unitary roofing sheet and the frame of the modular building unit.

The invention relates to a ventilation well with hurricane-resistant function for a building comprising an inclined roof (11), intended to be adapted to said building in such a way as to extend over its entire height, communicating towards the exterior of the building at the peak of the roof, and having at least one lateral opening (3, 4) communicating with the inside volume of the building, characterised in that it further comprises a cap (5) which may be adjustable in height and/or removable at the top of the well.

An expansion ring assembly seals a gasket with respect to an annular wall of a rigid structure. The expansion ring assembly includes two arcuate expansion ring bands that cooperate to define a generally circular profile. At one side of the expansion ring assembly, a first pair of ends of the expansion ring bands overlap and include a ratcheting mechanism which allows the ring to incrementally expand but not to contract. At another location of the expansion ring assembly, a second pair of ends are joined by a drive mechanism for engaging and driving apart the opposing ends of an expansion ring to thereby non-incrementally expand the ring. The ratchet mechanism may be used to initially set and hold the expansion ring against a gasket in a desired position and to provide an initial expansion pressure, i.e., for a coarse adjustment. The drive mechanism may then be used to provide a final expansion pressure of the gasket, i.e., for a fine adjustment. Advantageously, the coarse adjustment followed by the final adjustment allows a user to quickly and precisely achieve a desired gasket pressure by manipulating the torque applied to the drive mechanism.
