Abstract: Disclosed is a polyurethane foam comprising less than about 10 weight percent melamine and less than about 10 weight percent of one or more additional flame retardant compounds, both based on the total weight of the foam. In an embodiment, the weight ratio of melamine to the additional flame retardant compounds is in the range of from about 0.5 to about 2.0. The foam is a reaction product of one or more polyols, one or more isocyanates, one or more blowing agents, and one or more catalysts. In an embodiment, the foam has a density of within the range of from about 0.9 to about 4.25 lb/ft3, a 25% IFD in the range of from about 7 to about 150 lb/50 in2, and an air flow in the range of about 2.0 to about 5.5 ft3/minute. In an embodiment, the melamine is ground melamine.

Abstract: A carpet underlay including an effective amount of an antimicrobial compound. A rebonded carpet pad may include foam particles bonded together by a binder including zinc pyrithione. The underlay may include a laminating film on one or both sides of the pad. The laminating film may include zinc pyrithione as an effective antimicrobial.

Abstract: A refrigeration/rethermalization food service system is described. The system includes a food service cart having hot and cold chambers for receiving pre-plated foods. A hot air plenum is provided along a sidewall of the cart in the hot chamber, and a cold air plenum is provided along a sidewall of the cold chamber. To rethermalize foods in the hot chamber, heated air is forced into the hot air plenum from a docking station, and the heated air is evenly distributed from the plenum into the hot chamber. To refrigerate foods in the cold chamber, chilled air is forced into the cold air plenum from the docking station, and the chilled air is evenly distributed from the plenum into the cold chamber. The substantially uniformly distributed convective air currents provide substantially even heating and cooling of foods located in all portions of the hot and cold chambers.

Abstract: A method and apparatus for removing TDI from a gas in which the gas containing the TDI is forced through a scrubber tank. A first water spray is in fluid communication with the gas flowing through an inlet pipe and initially reacts the TDI in the gas with water. The gas is directed against a water surface at the bottom of the tank and thereafter, flows up an interior side wall of the tank. Deflectors mounted on the side wall disrupt the laminar flow of the gas and redirect it in a turbulent manner through a second water spray prior to the gas exiting the scrubber tank.
