Wiley Uses Almar 362 To Provide Smooth Hatch Cover Operation With large cargo ships it is neces-sary to have huge hatch covers that operate smoothly and quickly. If not -?it means lost revenue to the ship-owner. An important cog in the oper-ation of the cover is the axle, hinge and linkage system that needs to stay smooth and corrosion free for easy operation and maintenance. Wiley Manufacturing Company of Port Deposit, Md., a subsidiary of Microdot, Inc., switched to using Al-mar 362, a special alloy of high strength and excellent corrosion re-sistance in the making of these vital parts. Project engineers on the hatch cov-ers that range in size from 15 feet wide and 20 feet long to 27 feet wide and 45 feet long report that previous materials used caused some corro-sion problems because of the salt-sea atmosphere. They said the hatches would operate but that they would score the bearings and finally the hatch would take ten times as long to open if not corrected. The Almar 362 is made by Alle-gheny Ludlum Steel Corporation. Wiley tests the hydraulically oper-ated hatch sections so that they can be opened in one minute. On board the cargo vessels when installed the hatches are called on to open in about two minutes with some of the very large ones slightly longer. "We feel it is better to test the hatches at a faster rate here and we S/T KEYSTONER PROVES IT! PROTECT IT WITH FARBOIL The s.t. "KEYSTONER" has averaged only 45 gallons of coating on the entire hull per year for the last four years. In 1964, Farboil's Farbo-Coat 50/51 system was ap-plied to 75,000 sq. ft. of surface of the s.t. "KEY-STONER" from keel to rail. Since then only 182 gallons of Farbo-Coat have been used for touch-up of mechan-ical damage repairs. During this entire period, including the recent dry-docking, only 390 gallons of Super Tropical Anti-Fouling were used. At the first annual dry-docking, after the original system was applied, the ship was refloated without need for any coating or Anti-Fouling whatsoever. The s.t. "KEYSTONER" is just one example. Over two million DW tons of shipping are protected by Farbo-Coat 50/51 system, and more than 2,000 commercial vessels use Farboil paints and coatings. Prove it to yourself. Protect your fleet with Farboil. ELFflRBOIl COMPANY m A DIVISION OF BEATRICE 8200 FISCHER RD?

The Almar 362 material is pur-chased in 10- and 12-foot lengths and then cut to size as needed. The bar is purchased in 5, 4, 3, 2and inch diameters and then reground 0.015 before installing. The finished bars, pins and axle hinges range in size from 10 inches long to 6% inches long. Designed for the chemical process and industrial equipment industries, Almar 362 is well suited for Wiley's use because of its high strength and excellent corrosion resistance. York Trailer Appoints Canning Dir. Of Eng. Michael H. Conning Michael H. Canning has been appointed director of engineering of the York Trailer Company Ltd. Group, Northants, England. He joined York about a year ago as manager, research and develop-ment, and will continue to be re-sponsible for the group's technical development work, based at Mar-ket Harborough. Mr. Canning was previously with International Harvester in Chicago, where he was in charge of advance design work in the re-search and development division. Serodino Building Twin-Screw Towboat Serodino, Inc., Chattanooga, Tenn., has received an order from Blue Grass Barge Co., Inc., Nicholasville, Ky., to build a twin-screw towboat. The dimensions of this towboat will be as follows: 65 feet by 24 feet by 8 feet, and it will be equipped with 850-total-bhp diesel engines. Packaged Air Ejector Offers Space Spacing A packaged, two-stage air ejector has been developed by Schutte & Koerting Company, Cornwells Heights, Pa., to produce vacuum on the condensers used with steam turbines in nuclear, fossil-fueled, and marine powerplants. The ejector is unusual in that it utilizes "twin" first-stage and sec-ond-stage jet ejectors and a com-mon, surface-type inter and after condenser. The design provides an excellent capability in a compact, packaged form. Information on twin-element jet ejectors and other types of jet vacuum pumps can be obtained by writing to Dept. JA-74 Schutte and Koerting Company, Cornwells Heights, Pa. 19020. ' 54 Maritime Reporter/Engineering News
