"We''ve finished the GPS collection project for fire hydrants and have since GPS-ed storm drain inlets and about 20% of the water valves," says David Allen, GIS manager for Euless. "Our storm drain maps were generated for a Governmental Accounting Standards Board statement but are useful to the fire department in containing chemical spills."Another usedlawnmowers benefit: Firefighters no longer have to GPS-locate hydrants. "I typically go out and GPS the new ones as they are installed," Allen says. "Since this is only a few each month, it is easy for me to keep the maps current."

Pump it up"Centrifugal pumps have become more robust, with much tighter tolerances and stress analyses of components to increase efficiency and machine time to failure," according to Bruce Smith, North American sales manager for Fristam Pumps Inc., Middleton, Wis. Shaft deflection that results in moving parts hitting stationary components in the pump is a major contributor to pump failure, and manufacturers are addressing that concern.Liquid ring pumps are coming into play in the industry as an alternative to standard centrifugal pumps, adds Smith. Although these scavenger pumps have been around for a quarter of a century, pharmaceutical manufacturers have embraced the technology and forced redesigns that have expanded their applications. Liquid ring pumps are particularly adept at handling fluids with entrained air, an issue with cream, which tends to foam during transit. Liquid ring pumps do a superior job in fully evacuating a tank, a material-savings advantage that appeals to ice cream manufacturers and liquid egg processors, according to Smith. Pump improvements have been accelerated with the application of computational fluid dynamics (CFD) software, points out Russell Jones, business development manager-pumps for Alfa Laval in Pleasant Prairie, Wis. "From an R&D point of view, CFD is a big advance in optimizing design and increasing pump efficiency," he says. The technology has been instrumental in boosting pump efficiencies from the 40 percent range to 60 to 70 percent in recent years.

BIAM''s output this year? "We estimate we can make about 800,000 to 1 million (heads)," Yan said at the AMM conference. Grandis Metals'' rough estimate for worldwide annual consumption of titanium casting billet by the golf industry--excluding Japan but including the U.S., China and Japan--is 1,500 to 2,000 tonnes per year. The use of purchased scrap is between 700 and 1,000 tonnes, while sheet represents some 200 to 400 tonnes, bar 100 to 150 tonnes and welding wire 60 to 100 tonnes, according to Grandis. When Ruger Investment Casting built its Prescott, Ariz., plant in 1996-97, its entire output was dedicated-to golf club heads. Today, while Ruger doesn''t disclose golf''s portion, general manager John Thorne agreed that it was significantly less than the plant''s capacity. Ruger already is participating in, or actively pursuing, business in a wide range of markets, including marine applications, industrial, oil and gas and architectural products, among others.
