Hydraulic Institute Releases Air Operated Pump And Test Standards

The Hydraulic Institute (HI), Parsippany, N.J., has just added two new standards to its ANSI/HI Pump Standards: the American National Standards for Air Operated Pumps (ANSI/HI 10.1-10.5-2004), and the American National Standards for Air Operated Pump Tests (ANSI/HI 10.6-2004). Air Operated Pump Standard This new standard is for air operated pumps, including positive displacement reciprocating pumps used for general liquid transfer, which are driven by means of compressed gas (usually air) from an outside source. The pump may be designed with a single diaphragm or double diaphragms connected to a reciprocating shaft in which one side of the diaphragm is in contact with the liquid being pumped, and the other side is in contact with the compressed gas (air). The standard includes the following sections: • Types, Configurations and Nomenclature• Definitions• Design and Application• Installation, Operation and Maintenance Air Operated Pump Test Standard This new standard applies to the test of air-operated diaphragm and bellows pumps.

The New Soldier Field: Melding Tradition with Modern Convenience

As one of the founding teams in the league that would become the NFL, the Chicago Bears are steeped in traditions that run deeper than most. The roster of retired Bears jerseys on display in the lobby of the team headquarters is awe-inspiring, the names timeless: Blanda, Butkus, Ditka, Payton, Sayers. The faithful converge on Soldier Field every home Sunday, win or lose, to shiver in the open air as the wind howls off Lake Michigan. Even the stadium itself, until recently a crumbling Greek temple with peeling plaster and questionable plumbing, has been part of the team’s mystique for more than 30 years. In such a franchise, change does not come easy.

NRDC Demonstrates Green is Good with LonWorks-Based Open Systems

For more than three decades, the Natural Resources Defense Council (NRDC) has been a leading voice for environmental advocacy in the US. When the group decided to open a regional office in Santa Monica, California, they knew it had to be environmentally friendly. The building, named for Robert Redford, actor and long-time environmentalist, would combine cutting-edge technologies and materials with energy-efficient architecture to create a showcase for green-building design and promote environmental activism. The building, extensively remodeled by the NRDC and opened in November 2003, pushes the envelope for environmental design and construction techniques.
