Britain-Marine Industry (continued from page 27) Selby. The Appledore-built re- search vessel Charles Darwin has a 20-ton gantry for lowering and rais- ing survey equipment at the stern, and the Yorkshire Dry Dock cargo ships have MacGregor single-pull covers—to mention but a few of the latest installations in the U.K. Circle 52 on Reader Service Card NEI Clarke Chapman A part of Northern Engineering Industries, NEI Clarke Chapman is a long-time supplier of deck cranes, winches, and windlasses. Despite the general recession in shipping, the company has been expanding its production and work force, largely by taking advantage of opportuni- ties in the offshore industry. A joint venture company has been formed with the Australian Aquila Company to manufacture offshore cranes for the North Sea industry and mooring equipment. The com- Right—The crane shop at Clarke Chap- man's Victoria works. Shown are eight elec- tric deck cranes (two ship sets) for Blue Star reefers building at Harland & Wolff and an offshore crane for the Heimdal platform in the North Sea pany has acquired the assets of Donkin & Company, well known for the manufacture of steering gear, windlasses, and capstans. Among re- cent contracts are eight deck cranes for the four Blue Star reefers now under construction at Harland & Wolff, and an offshore crane for the Heimdal platform in the North Sea. The holding company, NEI, ac- quired the Pearlson Engineering Company of Miami five years ago, and manufactures hoisting equip- ment for that company's Syncrolift® ship-lifting platforms installed around the world including the two largest, at Todd Pacific Shipyards Corporation's Los Angeles Division, and the Vickers submarine facility at Barrow in Furness, U.K., which is now under construction. Circle 53 on Reader Service Card Perkins Perkins Engines in Peterborough, England, is a world leader in the design, manufacture, and marketing of diesel engines, including marine diesels in a range from 40 to 800 bhp, and outputs from 25 to 825 kva for generating duty. In March 1984 Perkins acquired the diesel engine business of Rolls- Royce Diesels International based at Shrewsbury, which raised its top output for propulsion engines from 350 to 800 bhp. The Shrewsbury engines are well suited for heavy- duty workboats, with conservative long-life ratings and appropriate op- tions such as clutched power takeoffs. Also incorporated are ser- vice features allowing long periods of continuous operation. The Shrewsbury engines also compete effectively in the light- duty commercial and pleasure sec- tors, where their efficient design, (continued on page 34) Raytheon Service Co. MARINE DEPT.

The heart of the Wilden air-oper- ated double diaphragm pump is its unique air valve which shifts the air supply to both dia- phragms alternately with com- plete reliability under all condi- tions of head and flow. Up to 90% solids and over 250' heads are no problem for the WILDEN PUMP. Our double diaphragm design cuts velocity in pump to half total discharge velocity. The most abrasive slur- ries are handled with ease since there are no seals and no metal to metal contact. Volume is infinitely variable by controlling air flow to pump, from a few gallons per minute to over 14,000 gallons per hour. No pressure relief valve is required and the pump can run dry inde- finitely. Wilden pumps are available with wetted parts in aluminum, cast iron, stainless steel, and Hastel- loy C. Non-wetted parts in alu- minum or cast iron. Elastomers in Neoprene, Buna N, Nordel, Viton®, and Teflon®. WILDEN PUMP Sl ENGINEERING CO. 22069 VAN BUREN ST., P.O. BOX 845.
