Abstract: Polyurethane cushions are formed on the surface of a textile such as carpet. The polyurethane is made in the reaction of a polyurethane forming composition that is frothed, and contains water as a blowing agent. The polyurethane forming composition is cured between the substrate and a containment layer, both of which prevent the blowing gasses from escaping during the curing process. The process allows low density attached cushions to be formed controllably.

Abstract: Pneumatic hurricane shutters are designed to temporarily cover a window or door in a building or other structure. The shutters have a lightweight rigid frame for surrounding the openings and mounting on fasteners attached to the building. Elongated pneumatic tubes are connected to frame rails and span the space between the rails to protect the opening. The frames can be locked in place to prevent inadvertent removal once in place. The frames and deflated tubes can be stored until the approach of a storm at which time the frames may be attached to the building and the tubes inflated to protect the openings.
