Harris Awarded $5-Million Addition To Navy R&D Contract for Satcom Work Harris Corporation, Palm Bay, Fla., has been awarded a $5-mil- lion modification for incremental funding under a previously awarded cost-plus-fixed-fee re- search and development contract for the Navy's EHF satellite com- munication program. The Naval Electronic Systems Command, Washington, D.C., is the contract- ing activity. Jacobs Joins Contromatics In Marketing/Sales Position The appointment of Christo- pher J. Jacobs, assuming the dual roles of vice president, mar- keting, and director of interna- tional operations, has been an- nounced by Contromatics' president John P. Kempton. In this new management position, Mr. Jacobs is responsible for marketing mat- ters and the development of an in- ternational manufacturing and sales network. He had been director, marketing and sales, with the subsidiary of STATE OF THE ART- PROFITABILITY. GEC making Fisher control valves in seven plants throughout the world. He was educated in Eng- land, was commissioned in the Royal Air Force, and joined his previous company in 1960 working for them in India, People's Repub- lic of China, Europe, Australia, and the U.S.S.R. in many diverse roles. Contromatics is a major manu- facturer of high-performance but- terfly and ball valves serving the marine process, power, and gen- eral service industries. Malcomson Named Manager Of Manufacturing For Raytheon And Sorensen Stanley Clark, president of Raytheon Marine Company and Sorensen Company, Manchester, N.H., has announced that Mal- colm R. Malcomson has been ap- pointed manager of manufactur- ing operations of these two Raytheon companies. He will re- port directly to Mr. Clark. Mr. Malcomson will be respon- sible for planning, procurement, production, product assurance, and inventory control for manufactur- ing operations for Raytheon Ma- rine and Sorensen products. Raytheon Marine produces ma- rine electronic navigation and communication equipment for ships, workboats, fishboats, and recreational boats. These products include radars, ARPA, loran, fish- finders, radiotelephones, and more. Sorensen produces linear, phase- controlled, and modular switching power supplies, as well as custom and semi-custom power assemblies for laboratory, industrial, and OEM applications. Before joining Raytheon, Mr. Malcomson was vice president of operations and president of Iotron Corporation; prior to that he was president of Mark Systems, Inc. Leslie Offers Data Sheet On Heavy Fuel Viscometer A free data sheet describing its heavy fuel viscometer is now available from Leslie Co. of Par- sippany, N.J. For proper atomiza- tion and maximum efficiency in a combustion system designed to burn heavy fuel oil, it is essential to control the viscosity of the fuel to a specific value. The Leslie di- rect viscosity control system with its balanced dual capillary princi- ple of measurement provides a constant viscosity for any mixture of a wide variety of heavy fuel oils. The viscosity of the fuel is meas- ured continuously (not periodi- cally sampled) and deviation from a specific value is corrected auto- matically.

How? Simple. Federal engineers every open and ducted propulsion system to help most any work boat attain maximum operational effi- ciency in fuel savings and maneu- verability.This, in turn, lowers your overhead costs and helps lead to optimum profitability. And to ensure that all propulsion, engine, hull and use requirements are perfectly matched, Federal offers customers a no-charge technical analysis and recommendation service. Power Thrust" is an excellent example of Federal's engineering expertise because it helps to reduce the stem vibration common to many work boats. Its rugged 4-blade design runs noticeably smoother than the standard 3-blade props it replaces. The extra area of four blades, which reduces diameter requirements, makes it ideal for in- stallations where clearance is limited. To resist damage, Power Thrust is cast with heavy cross- sections and leading edges. Avail- able in Federal-formulated "B" bronze, Ni-Bral or CF3 mod stain- less steel, it's highly resistant to corrosion, too. Diameters up to 72 inches are standard. Federal Ducted Systems deliver an optimum level of operational efficiency due to their technically- advanced design. They feature a 4-blade Kaplan-style propeller, installed inside either a steel or fiberglass nozzle. This Federal engineered ducted propeller sys- tem will deliver either more thrust with equal power, or comparable thrust with less power when com- pared—size for size—with open props. Typical bollard thrust increases range from 40 to 50%. Fuel savings up to 25% are also commonly reported.
