to be separate units, and for the in- line engines are of nodular cast iron. Unlike the original designs, the 8- and 9-cylinder bedplates and frames are monobloc castings secured by tie-rods. On the other hand, the Vee-type engines have a welded steel bedplate and a special cast iron frame for which tie-rods are not nec- essary and are therefore replaced by stud bolts.

(NAO), a Philadelphia, Pa., process equipment manufacturer, has introduced the Portable Burner Ignitor (NPBI). The hand-held unit is used to ignite burners in boilers and process furnaces and is the new- est development from NAO. Safe, easy and inexpensive are features of the NPBI. The unit is safe to operate since direct contact with the flame is avoided. The igni- tor is controlled by the operating push button. Another feature of the NPBI is that it is easy to work. A small disposable propane cylinder is attached to the ignitor handle, then the ignition switch is flipped "on" and pressed until the ignitor is lit. In addition to being safe and easy, the unit is also inexpensive. The total cost of the unit is less than $200, plus $2 to $3, the cost of a dis- posable propane cylinder. Other advantages of the Portable Ignitor include durability, long life, lightness, and assorted ignitor lengths. Areas exposed to heat are made of stainless steel for extended life, without affecting the light- weight design. The ignitor weighs less than two pounds, and is avail- able in three standard lengths—36, 48 and 60 inches. NAO is an internationally known manufacturer of combustion and pollution control equipment since 1912, and maintains offices in Hous- ton, Texas; Tokyo, Japan; Milan, Italy; London, England, and has agents around the world.

The three, plus another now under construction in France, will give Royal Caribbean an eight-ves- sel fleet. The new vessels, to be named the Nina, the Pinta, and the Santa Maria, are two tenders and a utility boat for use at Labadee, the line's new port of call on the northwest coast of Haiti. The two tenders, designed by the line's senior marine superintendent Thorlief Berg, will be 72 feet long, 25 feet wide, with a draft of 6 feet. They will each accommodate 250 passengers for the five-minute ride from the Song of Norway (another of the line's cruise vessels) to La- badee's passenger pier. The Santa Maria is scheduled for delivery this month, with christen- ing ceremonies to be held in Miami at Royal Caribbean's berthing facili- ties on the Port of Miami. The Pinta is a utility vessel, fitted for cargo duty in support of the pas- senger activities at Labadee. Only Westfalia's OtvDemand Purifying System Removes M the Dirt and Water from your 1010 fuel. Whether your fuel oil is heavier or lighter than water, only Westfalia's two-stage Unitrol/Secutnol system assures maximum purity even under widely varying feed conditions. Here's why. On-demand vs timer-controlled de-sludging. Other oil purification systems are timer-controlled, which means they de-sludge only at pre-set intervals. If heavy seas stir-up the "muck" in your fuel tanks, the intervals may be too far apart. Result: dirt gets into your day tank and fuel lines, causing disastrous engine wear...In the Westfalia system, a unique sensor continuously monitors de-sludging intervals, discharging dirt and water only when the sediment-holding compartment is full. So there's no chance for dirt to get into your fuel because of too few de-sludgings — or fuel wastage from too-frequent de-sludgings. And either stage can be operated independently, thus adding even more flexibility. No water in fuel lines. With Westfalia's unique design, there's no way water can enter the clean fuel line. With other systems, this is a distinct possibility. Reliable purification. No matter how wide the variations in density or feed characteristics, you get the most efficient, reliable purification. Automatically, with no need for gravity disc changes. For maximum reliability we've substituted simplicity for complex electronics and intricate circuitry. Thus Westfalia purifiers are more dependable and much less likely to break down than other separators. Contact Centrico for the Westfalia system you need. Westfalia is proud to be part of the ongo- ing construction program of the new and growing U.S. Navy. Centrico, Inc., 100 Fairway Court, Northvale, N| 07647 (201)767-3900
