Abstract: A powder coating composition comprising an intimate mixture of at least one thermoplastic and/or thermosetting resin binder and optionally, at least one crosslinking agent and constituents conventional in powder coating compositions, such as, pigments, fillers and additives, comprising aluminum particles having a D50 in a range of 8 to 20 ?m whereby the aluminum particles are treated with compounds selected from the group consisting of silica, (meth)acrylic polymers, polyesters and wax; the powder coating composition provides coatings with a value of thermal emissivity in a range of 0.4 to 0.55 with total solar reflectance values in a range of 60 to 70% in the infrared (IR) and/or near IR (NIR) wavelength region of 0.3 to 2.5 ?m, to minimize the heat transportation through a substrate coated by the powder coating composition, e.g., from a warm building to a colder environment.

Abstract: A portable system for air separation or air dehydration, or both, is carried on a truck or equivalent vehicle. The air separation system includes, at a minimum, a feed compressor and a gas separation membrane. The air dehydration system includes a feed compressor and an air dehydration membrane. The feed compressor receives power from the engine of the vehicle, only when the vehicle is not moving under its own power. Heat from the vehicle engine may also be used to heat the compressed air stream to prevent the formation of water. The system can also be used to perform air dehydration and air separation simultaneously. The system is substantially self-contained, and can be easily driven from one location to another, simply by driving the vehicle to another location. The invention is especially useful in providing air separation or air dehydration services, or both, for relatively brief periods, at multiple locations.

Abstract: A system for making dry, hydrocarbon-free compressed air includes a compressor, a membrane drier, and a carbon bed connected in series. A moisture separator may also be included to remove liquid water from the stream. A filter may be placed after the carbon bed to remove residual carbon dust. The output of the system can be connected to operate virtually any pneumatic device, such as a control valve or pneumatically-operated instrument. Because the chemical content of the compressed air is not changed, it remains breathable, and does not create a safety hazard.
