Find hereIn the palm of his handUntil recently, when a prospective buyer would come to the Koupal Angus ranch near Dante, South Dakota, to look at bulls, La Vern Koupal (pictured at far left) would grab a thick stack of records and carry them out to the rolling pastures. "I''d be digging through the papers, and the wind would be flipping the pages, and I could never find the right page," says Koupal.Now he takes his $850 Palm Pilot Out of his coat pocket, writes in a bull number, and instantly gets all the production and bloodline information he and the buyer need. "It''s unreal what this technology can do," he says. 4. Air Dryers. Air dryers remove both liquid and water vapor from the compressor discharge air before it reaches the air brake system. They can be either heat exchangers or equipped with a desiccant type in-line filtration system. They are essential in the prevention of air line freeze-up, and they keep the air system free of moisture. Brake diaphragms, seals and other plastic or rubber parts live much longer in a clean dry atmosphere.5. Combination quick release valve and gladhand that combines the functions of the trailer brake quick release valve and the service gladhand. It reduces brake release lag time to within a half a second. Benefits include less brake drag saving fuel and extending brake lining life. 6. Better matching of tractor and trailer air brake systems. Vehicle manufacturers are now treating the tractor trailer combination as one unit in order to obtain more standardization of valve crack pressures, brake piping sizes, plus application and release timing. NITROGEN GENERATORSNitrogen generators use either membrane or pressure-swing-adsorption (PSA) technologies. Membrane generators made by Balston, a division of Parker, produce up to 99.5% pure, commercially sterile nitrogen at dewpoints to -58[degrees]F from compressed air. They use proprietary membrane-separation technology to divide air into two streams: one 95 to 99.5% pure nitrogen, the other oxygen-rich with carbon dioxide and other trace gases.Compressed air flows through bundles of individual, hollow fibers made of semipermeable membranes. Each fiber has a perfectly circular cross section and a uniform bore through its center. Because the fibers are so small, a great many can be packed into a limited space, providing enough surface area to produce a relatively high-volume flow of nitrogen. ©2003 www.concrete-saw.net.
