The inaugural honor fell to Kent Line's 108-meter- long (about 354 feet) vessel Arroyofrio Uno of 5,080 dwt which loaded a cargo of trailers bound for Zeebrugge and by so doing commenced a new daily service that will run between Dartford and the Belgian port. Centerpiece of the new "miniport" is the por- table MacGregor-Navire (MGN)-designed pon- toon and bridge ramp which, designed to cope with tidal extremes as high as 9.66 meters (about 31V2 feet), is the essential element enabling the horizontal loading of cargo—the pivot around which the project has revolved. The Dartford linkspan, being T-shaped, is designed to service two RO/RO vessels simulta- neously. Vessel lengths of 200 and 150 meters can be accommodated on the downstream and upstream berths, respectively. Vessels of up to 23,000 dwt and 36-foot draft can use the facility and adjustable "landing" ramps at each end of the pontoon will enable ships having threshold heights of between 0.875 meters and 3.37 meters above water level to use the berths. The 2,6002 surface area of the pon- toon and the 8 meter clear width of the bridge ramp is designed to provide ample room for turning traffic and for its transit to the hard- The first ship to berth at the new MacGregor-Navire- designed linkspan situated at Dartford, U.K. on the River Thames, the Arroyofrio Uno, is shown as she embarks a cargo of trailers bound for Zeebrugge, Belgium. Regarded as a new "gateway to Europe," this new RO/RO ferry terminal is expected to make a major impact on U.K. Con- tinental freight shipments. standing area ashore in two simultaneous lanes. The unit was design-appraised and built un- der the survey of Lloyd's Register and is classed as being suitable to withstand the most severe requirements laid down for road bridges. The successful completion of the Dartford International Ferry Terminal (DIFT) represents a high level of technical and commercial achievement for all concerned. Certainly it is confirmation that MacGregor-Navire's exten- sive linkspan technology, harnessed to other fac- tors such as the unrivalled road and rail trans- port links of the Dartford location, can make a major impact on the life of a region.

According to the manufacturer, this unique actuator fills applications in any piping system involving automatic valve operation where the valve must quickly close (or in certain instances open) in the event of air supply or electrical fail- ure, thereby providing for more reliable fluid handling. The Jamesbury V15SR is made of polyester thermoplastic and stainless steel construction which makes the actuator extremely corrosion resistant—this is not a coating, but a unique molded polyester thermoplastic construction. The Jamesbury V15SR is rated at 60 psi sup- ply pressure (125 psi max.), suitable for operat- ing ball valves in lA -inch to 2-inch sizes. The actuator is available in both spring-to-close and spring-to-open designs. It is an extremely com- pact actuator and weighs only five pounds. The spring return cartridge is a sealed housing with a spring of infinite life design. A high visibility position indicator is mounted on top of the spring return cartridge. Optional limit switches mount directly to the V15SR without requiring linkage. For more information and free literature from Jamesbury, Circle 233 on Reader Service Card
