New Early-Warning Device Protects Electric Motors- Literature Available Insulation failure is by far the most frequent cause of costly burnouts in marine electrical ma- chinery. While a motor or gen- erator is idle, its coil is under continuous attack by shipboard atmosphere and contaminants. In- sulation resistance eventually drops below safe levels. If the condition is undetected, a burnout results seconds after start-up. Ex- pensive rewinding is required and, when the affected motor is essen- tial and non-redundant, the re- sulting delays can be far more costly. Marine Safe Electronics of Can- ada, Ltd., is now offering the ma- rine industry an economical al- ternative. The Fail-Safe (patent pending) motor generator protec- tor is an early-warning device that promises to prevent virtu- ally all such burnouts. Easily mounted in the starter enclosure of motors or on the main switchboard of generators, the device continuously monitors insulation resistance in idle ac equipment. When resistance falls below a preselected level, the Fail- TELLS ALL. mi-mm saraim mmt:m One of the main reasons that our ESZ-4000 is the world's fastest- selling satellite navigator is , because it tells everything you j want to know — without even being asked. Every detail of where you are and where you're headed is constantly dis- played. Including position, time, speed, heading, and course and distance to any one of nine prestored waypoints. And with the push of a single button, you can read tne next ten satellite passes and the last six fixes. THE INSIDE STORY. Automatic inputs from speed lo; and gyro are standard, not option; And between satellite fixes, the ESZ-4000's computer updates your satellite naviga- tor's unmatched reliability, three-year warranty, worldwide shipboard service, ship's position every 10 seconds, using computed set and drift to make sure deaa-reckoned position is as accurate as possible. The more accurate the navigator, the more miles you'll save. The more time. And fuel. In fact, a large vessel may save the cost of the ESZ-4000 in the course of a single voyage. No wonder Navidyne has sold more ESZ-4000s than any other single model on the market. WAIT THERE'S MORE.

The device is U.L.-listed and has been approved or accepted worldwide by the U.S. Coast Guard, American Bureau of Ship- ping, Lloyd's Register of Ship- ping, Det norske Veritas, and Germanischer Lloyd. It has com- pleted an extensive testing pro- gram on several major vessels, with results meeting or exceed- ing the manufacturer's expecta- tions.

Zapata Completes Acquisition Of Offshore Marine Limited Of U.K. Zapata Corporation has said that the previously announced ac- quisition of Offshore Marine Lim- ited from The Cunard Steam-Ship Company Limited, a Trafalgar House Limited subsidiary, has been completed. The acquisition, by Zapata Off- shore Services Limited, Zapata's U.K. subsidiary, involved 24 off- shore oilfield supply vessels. Za- pata's marine service fleet now totals 75 vessels, which work un- der contract to offshore operators worldwide. Zapata Corporation is a diversi- fied natural resources company, primarily involved in the devel- opment of energy and proteins. In addition to marine services, its businesses include offshore drill- ing, oil and gas operations, ship- ping, coal mining; commercial fishing and related processing; and construction and dredging.
