New Carboline Guide

Protective Coatings

The Carboline Company of St.

Louis, Mo., has released a new 35- page guide containing detailed tech- nical data on the company's full line of inorganic zinc protective coatings.

The guide contains information on a new economical primer, a fast dry primer for shop application, a fully weldable primer and others. Test da- ta, cost comparisons, recommenda- tions and product data sheels are also included. A useful chart tells when to use inorganic zinc coatings and when to use hot dip galvanizing to protect steel.

Tug Convention Papers

Now In Book Form

There are very few works of ref- erence for the tug designer, builder or owner. Most of them have been produced by Ship & Boat Interna- tional in the form of proceedings of their tug conventions. "Proceedings of the First North American Tug

Convention" is the third such book to be produced as a result of a gathering of owners, designers, builders, seamen, manufacturers,

Government officials, surveyors and other professions. The fact that this convention took place in Van- couver and did not have the appel- lation "international" should not be allowed to fool anyone. It was as "international" as the previous conference, held in London.

The standard of the papers pre- sented in Vancouver was perhaps higher than that of the two previ- ous conferences held in London.

Once again there was an inter- change of ideas among all sections of industry; once again there was much discussion "out of school," as one author put it; once again dele- gates were made aware of problems they had never faced or solutions they had never thought of; once again business contracts were set up and friendships cemented.

This book, edited by Kenneth D.

Troup, follows the same format as the previous copies, where the paper is printed in full and followed by the discussions, presented in a verbatum form. It is quite obvious from the quality of the written word that the various industries represented at the conference had sent their most qualified personnel.

There is no doubt that this vol- ume will take its place with its predecessors as a standard work of reference. Copies may be obtained at a price of $30 each from Thomas

Reed Industrial Press Ltd., Sa- racen's Bead Building, 36/37 Cock

Lane, London, E.'C.IA 9BY, Eng- land.

Peter H. Gunn

Joins Pacific Marine

Pacific Marine Corporation, ship- brokers, (a 'Delaware corporation), announced that Peter H. Gunn,

A.I.C.S., has joined the firm as a sale and purchase broker. Mr. Gunn will handle Pacific Marine's new- building contracting and second- hand ship sale activities. He brings with him 15 years' experience in the London sale and purchase mar- ket.

Pacific Marine Corportaion, with offices in New York, London and

Tokyo, offers a complete shipbrok- ing service, all offices now having three separate departments, each devoted to tanker chartering, dry cargo chartering and sale and pur- chase activities.

Miss Kari Dahl, formerly with leading Oslo brokers, has been pro- moted to assistant to Mr. Gunn, concentrating on the Norwegian market.

They couldn't stretch the hull, so we shrank the gearing.

The unusual hull design for this new roll-on roll-off ship really put the squeeze on its propulsion ma- chinery.

Two 9000 HP Pielstick diesel engines, made by

Crossley Premier Engines Ltd., and their gear re-

The 20,000-ton "RO-RO" Laurentian Forest, built by Port Weller Dry Docks Ltd., St. Catharines, Ontario, for Burnett Steamship Company, will carry newsprint to Europe and return with trucks and cars. ducers, had to fit into a pair of restricted pods.

And the gearing to reduce the engine output speed from 520 rpm to 110 rpm was specified as

Lloyd's Ice Class 1. This meant 25% higher rating — actually 11,250 HP — to withstand propeller shock loading from ice in the North Atlantic.

Conventional "soft gearing" would have re- quired a bull gear 50% greater in diameter — much, larger than the available space—or alternately a face-width so extreme that problems of deflection and end loading of teeth would have made the de- sign unsatisfactory.

The solution: Philadelphia Gear Reducers, with case-hardened and ground gearing. The bull gears were the biggest single helical hardened and ground marine gears ever made in this country.

But for this application, they were unusually com- pact; actually, 40% smaller than "soft" gears of the same capacity, because of the extra load trans- mission capability of hardened and ground gears.

Before you gear up for your next ship, let's get together and reduce the problems. Write Philadel- phia Gear Corporation, King of Prussia, Pa. 19406.
