Abstract: Disclosed herein are fiber reinforced cement composite materials incorporating a fiber blend that includes cellulose pulp and synthetic fibers in a ratio selected to provide the composite material with improved water absorption characteristics and the same or improved mechanical properties as compared to equivalent composite materials reinforced with predominantly or all cellulose fibers. Also disclosed herein are fiber blends comprised of a combination of cellulose fibers and polypropylene fibers adapted to reinforce cementitious composite articles manufactured by the Hatschek process and autoclave cured.

Abstract: A direct evaporative air handler for providing supply air to humidify and cool an enclosed space such as a data center. The air handler includes an evaporative cooler and a return air port that is positioned upstream of the evaporative cooler to allow recirculated air from the enclosed space to pass through the evaporative cooler. The air handler includes an additional return air port that is positioned downstream of the evaporative cooler to allow recirculated air from the enclosed space to bypass the evaporative cooler. The air handler includes an outdoor air port that is positioned upstream of the evaporative cooler to allow outdoor air to pass through the evaporative cooler and further includes an outdoor air bypass port that allows outdoor air to enter the air handler without passing through the evaporative cooler. The temperature and humidity of the supply air can be controlled under various ambient conditions by controlling the amount of air that enters the air handler through each port.

Abstract: An integrated air handling system having a make-up air system that treats outside air and a recirculating system that mixes the treated outside air with building return air. The make-up air system may include a filter, a dehumidifier, a humidifier, a combination of a dehumidifier and a humidifier, and/or an exhaust fan. The mixed air is supplied to a structure.

Abstract: Described herein are articles for handling and use that include one or more spaces in predetermined and select locations. The one or more spaces may be more centrally located, on the edges of the article, on opposite edges of the article or in one or more positions that aid in handling and use of the article. The shaped spaces may be in any form, wherein simple shapes are more cost effective, such as those that resemble a square, rectangular, circle or oval.
