A composite multi-layer barrier is produced by first vapor depositing a barrier under vacuum over a substrate of interest and then depositing an additional barrier at atmospheric pressure in a preferably thermoplastic layer. The resulting multi-layer barrier is then used to coat an article of interest in a lamination process wherein the thermoplastic layer is fused onto itself and the surface of the article. The vacuum-deposited barrier may consists of a first leveling polymer layer followed by an inorganic barrier material sputtered over the leveling layer and of an additional polymeric layer flash evaporated, deposited, and cured under vacuum. The thermoplastic polymeric layer is then deposited by extrusion, drawdown or roll coating at atmospheric pressure. The resulting multi-layer barrier may be stacked using the thermoplastic layer as bonding agent. Nano-particles may be included in the thermoplastic layer to improve the barrier properties of the structure. A desiccant material may also be included or added as a separate layer.

A roofing shingle for enhanced wind/rain durability embodies two transverse lines of adhesion. A first discontinuous line of adhesive joins the butt edge of an overlying shingle to the underlying shingle. Secondly, a band of sealant adjacent the top edge of an underlying shingle seals against an overlying shingle to prevent penetration by wind driven rain to the roof deck. A reduced headlap is thereby permitted, thereby either reducing shingle size or extending shingle coverage. Exposed portions of the sealant band improve the erosion resistance of underlying shingles.

A method and system for improving gas exchange properties of oxygenators which utilize hollow fiber membranes for removing carbon dioxide or adding oxygen to a patient's blood via extracorporeal circulation by removing moisture accumulating in the fibers are disclosed. The system utilizes a vacuum source for drawing sweep gas into the oxygenator, a moisture collection unit for storing moisture removed from the oxygenator, the moisture collecting unit being in communication with the oxygenator and the vacuum source and a flow control mechanism having an open position which allows sweep gas exiting the oxygenator to flow to the moisture collecting unit and a closed position which stops the flow of sweep gas from the oxygenator to the moisture collecting unit. The vacuum source draws sweep gas through the oxygenator and moisture collecting unit when the flow control mechanism is in the open position and the vacuum source creates a vacuum buildup in the moisture collecting unit when the flow control mechanism is in the closed position. The vacuum in the moisture collecting unit provides a sudden increase to the flow rate of the sweep gas to draw moisture with the sweep gas exiting the oxygenator when the flow control mechanism is returned to the open position.

Thermal processing of recycled asphalt pavement (RAP), having up to approximately 8% or more moisture content, dries and preheats the material to enhance efficient recycling in a hot mix asphalt plant. A combustor and heat exchanger reheat circulating hot oil, which with hot gas, moves through a hollow auger and around the RAP counter to the flow of RAP. Moisture is forced outward from within the particles and is flashed away by the hot exhaust gas. A similar secondary heater heats the RAP to just below asphalt coking temperature before the hot dry RAP is added as an aggregate to the hot mix asphalt plant.

The invention relates to improved resin bonded sorbent compositions and articles of manufacture fabricated therewith, such as air conditioning and refrigeration components. The introduction of desiccants into resinous molding compositions enables the elimination of more conventional bagged desiccant containments. The novel molding compositions of the invention and parts fabricated therewith are multi-functional, beneficially combining structural, mechanical and adsorptive capabilities without requiring the usual reinforcing additives. Consequently, with the omission of reinforcing additives the novel molding compositions of the invention are further characterized by higher moisture adsorptive capacities by allowing for higher sorbent loading factors than prior adsorbent-containing molding compositions.

A sensor and detection methods are provided for detecting nitric oxides (NOx) in an exhaust gas based upon ion mobility spectrometry (IMS) technique. An ionization chamber having an interior electrically conductive shell receives exhaust gas. A spark electrode having a needle tip extends into the ionization chamber. A shutter grid is coupled between the ionization chamber and an ion drift tube. A substantially continuous spark discharge is established between the electrically conductive shell and the needle tip of the spark electrode for ionization of the exhaust gas. Negative NO₂ ions are kept inside the chamber by biasing the electrically conductive shell and the shutter grid at a negative voltage. Then a positive pulse is applied to the shutter grid to cause the shutter to open for negative NO₂ ions to exit into the ion drift tube. The IMS sensor is small-sized, low-cost, robust, and reliable.
