<BODY> <div> Spectra Composites Take Undersea Exploration To Greater Depths The Naval Ocean Systems Center (NOSC) is now using Spectra® fi- bers for reinforced composites in the fairing—or hydrodynamic hull— and in the internal mounting struc- ture of its unmanned submarines, which are technically called Ad- vanced Underwater Search System Vehicles (AUSS). Spectra fibers, engineered by Al- lied-Signal Inc., provide unique combination of a high strength-to- weight ratio and minimal signal dis- tortion for undersea supplications. Pound for pound, Spectra fibers are 10 times stronger than steel. And, its near-zero dielectric constant per- mits excellent signal transparency. In addition, Spectra fibers exhibit outstanding chemical/abrasion re- sistance and low moisture regain. Other undersea applications be- ing considered or now utilizing Spectra composites in structural support systems include: unmanned submarines and submersible robots used for mine detection, sea floor mapping, geological testing and Two good investments, ||| •5 z i * ? photography, plus vessel recovery equipment.

State-of-the-art presentations about the underwater industry will cover welding equipment and pro- cesses, mechanical and internal weld properties, maintenance and inspection procedures, and welding applications in shallow and deep water. Fifteen papers will explore a wide range of current interests, including "State-of-the-Art Developments in the Underwater Welding Industry"; "New and Future Underwater Welding Equipment"; "Underwater Nondestructive Testing Tech- niques"; "Semi-Automatic Wet Welding"; "History of Structures in Service—Followup Inspections"; "Underwater Welding Applications in Shallow and Deep Water"; "Proven Procedures for Underwater Project Management"; and "Auto- mation and Robots in Underwater Welding."

Aqua-Chem, Inc., Milwaukee, Wis., recently announced plans to move to a new office facility in Trammell Crow's Park Place on the northwest side of the city. The glass and brick structure, now under con- struction, will house Aqua-Chem's corporate staff and two of its divi- sions, Cleaver-Brooks and Water Technologies. The announcement was made by Bob Agnew, president and CEO of Aqua-Chem, Inc., who explained that consolidating the company's 325 Milwaukee employees in one central location will be very useful in improving communication and overall effectiveness. Aqua-Chem has been solving tough problems with innovative technology for nearly 50 years. The company pioneered portable battle- field distilling plants to purify salt water and brackish water during World War II. It then developed the first of thousands of distilling plants for ships, offshore oil rigs, power plants and major land-based desali- nation systems.
