Abstract: Structurally sound quick assembly reusable housing shelters are assembled at disaster sites. These rapidly deployable shelters are assembled on site, and can be disassembled after their use is complete, and deployed to another disaster location. The components are built in a factory setting, so that all the tolerances can be maintained. The identical components are interchangeable. Wall and roof panels of the shelters are coated with a rugged polyurea coating, which is waterproof, mold-proof and with no corrosion. Identical T-shaped uprights are spaced equally apart along an outer perimeter of the shelter. The wall and roof panels nest in place between adjacent T-shaped uprights, which each have a flat backend and a centrally located, perpendicular protruding buttressing web extending outwardly from shelter's exterior. T-shaped roof rafters spanning respective uprights of the housing shelter unit, and have notches engaging upper portions of each upright, or vice versa.

Abstract: A non-rotary, linear reciprocating floor sander includes a housing having a bottom opening, wherein a rotating electric motor is supported by the housing. A vertical output shaft extends within the housing and engages gears controlling a pair of flat platens enclosed above and on sides by the housing. The platens have lower surfaces with bonded sandpaper pads adapted to be in contact with a floor to be sanded. The vertical output shaft controls reciprocating movement of the platens linearly in a plane in opposite directions, so that the platens move toward and away from each other, thereby reducing little induced force or vibration transmitted to the housing.

Abstract: A crush resistant seamless roofing system is formed by a layer of adjacent panels having loose joints filled by expanding rising foam adhesive, which is trimmed to remove excess foam adhesive above a top plane of the roofing system. The roofing system thus formed is covered by a fabric layer and a coating. Further, the seamless roofing system is combined with a base layer, located beneath the panels, the base layer comprising bonded panels of a lightweight fireproofing material, resistant to moisture and foot traffic.

Abstract: An electrical generating system includes a plurality of linear operating magnetos impeded within a roadway pavement, whereby the passage of vehicle wheels from moving motor vehicles directly depresses linear solenoid plungers for generating electricity, without the need for the extra energy consumption drawbacks, such as bellows, compressed air or ratchet mechanisms.

Abstract: A method and an industrial robotic device for uniformly applying coatings at appropriate thickness and pitch upon a surface moves a spray applicator foam dispenser between two parallel tracks. The uniform application of foam at each pass is assured, by accelerating the speed of the foam dispenser at the end of each pass, by providing respective curved uphill distal ends of the tracks, so that the spray applicator foam dispenser moves up the curved distal ends and returns quickly while changing speed tilt and direction at the end of each pass.
