Lockheed Oil Spill Remover On Display In San Francisco The shiny new prototype of an oil spill re- moval device, which resembles the paddle wheel of an old river boat, recently went on display in San Francisco, near famed Fisherman's Wharf. Called Clean Sweep by its developer, Lockheed Missiles & Space Co., of Sunnyvale, the four- foot-diameter, seven-foot-long Clean Sweep unit is mounted between the twin hulls of a catamaran. The Clean Sweep on display is a production prototype of oil recovery devices which Lock- heed plans to build and market to companies, consortiums, refineries and Government agencies engaged in combating oil slicks. Lockheed recently received a patent for Clean Sweep, and the firm has been awarded a contract by the U.S. Coast Guard to develop an air- transportable eight-foot-diameter unit to tackle high seas oil spills. The Clean Sweep concept is a series of parallel metal discs joined by overlapping metal vanes set in slots around the outside edge of the "drum." As Clean Sweep rotates in a slick, oil is drawn into the drum and adheres to the sides of the discs. Wiper blades set permanently at a near vertical position inside Clean Sweep wipe oil from the discs. The oil runs into a central channel inside the unit's axle is pumped to storage. The metal vanes act to draw oil inside Clean Sweep. As they move up the back side of the rotating unit, their overlapping position prevents excess oil from passing out of the drum. Following its display on the San Francisco waterfront, the catamaran-mounted Clean Sweep will be used for testing prior to the start-up of production for commercial units. Hamlet And Rawson Named GE Marine Sales Managers Robert F. Hamlet Edward M. Rawson Robert F. Hamlet has been appointed Gen- eral Electric's regional marine sales manager for the Gas Turbine International Operations, and Edward M. Rawson has been appointed GE's manager of marine gas turbine propul- sion system sales in Europe. The announce- ment was made by Agostino J. Travaly, man- ager of gas turbine marine sales for the Gas Turbine Business Operations. As manager of regional marine sales, Mr. Hamlet is responsible for the development of marine heavy-duty gas turbine business in the European area. Prior to his recent appointment, Mr. Hamlet held several marine sales positions, including a position as sales engineer for GE's Marine Sales Organization in New York. He was re- sponsible for major shipowners and oil com- panies. A graduate of the Massachusetts Mari- time Academy, Mr. Hamlet received a B.S. de- gree in marine engineering. He has been in GE's marine business since 1957, when he join- ed GE's Marine Turbine and Gear Department in Lynn, Mass. Based in London, England, Mr. Rawson is responsible for the sale of marine heavy-duty gas turbine propulsion systems. Prior to his recent appointment, he was marine sales rep- resentative for the Far East and Australia. Mr. Rawson, a graduate of the Massachusetts Mar- itime Academy with a B.S. degree in marine engineering, has been in the marine business with GE since 1956. He has held sales posi- tions in the Marine Turbine and Gear Depart- ment, Lynn, Mass., the Domestic Marine Sales Operation, New Orleans, La., and the Industry Control Department's marine operation, Ro- anoke, Va. According to Mr. Travaly, "The rapid world- wide growth of gas turbine marine business re- sults in our expansion of manpower abroad to meet the needs of the maritime industry." GE is the world's leading producer of gas turbines which are used worldwide by the mar- itime industry, electric utilities, and gas trans- mission companies. Market growth for gas turbines has more than quadrupled from 1965 to 1970. Mooremack Seeks Subsidy For Refitting Six Freighters Moore-McCormack Lines has applied to the Maritime Administration for a Federal subsidy to help meet the estimated $978,768 cost of re- fitting six of its C-4 Constellation class freighters for additional container capacity. The line said it will spend $163,128 on each ship to install deck fittings for 96 containers, and convert some of the fittings for 40-foot units to accommodate 20 footers. Most of the cost per ship, $107,884, will go for structural changes in hatch covers. The six ships were delivered in 1964 and 1965 and are now employed in service between U.S. Atlantic ports and the East Coast of South Amer- ica and between the U.S. Atlantic ports and South and East Africa. The vessels have a speed of 24 knots and carry a 36-man crew. Each ship has accommo- dations for 12 passengers. Fast, efficient and highest quality drydocking and repairs in Hong Kong '-•mf^i.
