WRITE FOR CATALOGS ON OUR MARINE SHAFT SEALS AND ALSO OUR RP/MECHANICAL SHAFT SEALS SYNTRON A DIVISION OF FMC CORPORATION 398 Lexington Ave. ? Homer City, Pa. 15748 Telephone 412-479-8011 69MS1 "Face Type» Marine Shaft Seals Are Right Up Your Alley. Positive sealing, long life, low maintenance. Never need adjustment, nor will they score or gall shafts. SYNTRON sealing components can be replaced without drydocking. Up to 48" dia. THIS IS THE SEAL! The decision to use the Voith Schneider Propeller system (verti-cal-axis propeller providing con-trollable pitch and thrust direction) was based on the excellent experi-ence in Europe and the unique way in which these units solved so many operational problems, the au-thors explained. Both the 165-foot, 41-car Galena and the 131-foot, 28-car Needles land on a concrete roadways with a 1 :10 slope which are part of the highway. The level of the lake va-ries as much as 70 feet during the year. There are no guides for the ferries so they must be able to position themselves and hold their positions during loading and un-loading. The ability of the V.S.P. system to produce thrust in any direction provides this capability. Further considerations were ease of repair and low headroom re-quired. The Galena's V.S.P. units, one at each end, are located 18 feet 7yi inches off the centerline, one being to port and one to starboard. Each unit is driven by a 350-hp electric motor driving through right-angle gears. Electric power is supplied by four diesel-driven 250-kw, 460-volt, 3-phase, 60-cycle generators, with any three operat-ing in parallel at one time. Service speed was given as 10 knots. The Needles' V.S.P. units are located on the boat's centerline, one forward and one aft. They are each driven by a 225-hp diesel en-gine connected to the V.S.P. by a 1.82:1 reduction gear, two flexible couplings and line shafting. Serv-ice speed was given as 7 knots. American Ship Buying Nashville Terminal And Other Facilities The American Ship Building Co. has announced the signing of a preliminary agreement to purchase the terminal business and certain other assets of Central-Cumber-land Co. and Cumberland Storage & Warehouse Co., both of Nash-ville, Tenn. George M. Steinbrenner III, chairman and chief executive offi-cer of American Ship, and Dr. Ja-cob O. Kamm, president, indicated the purchase was accomplished through an exchange of American Ship common stock. Purchase price was in the area of $1,000,000. Assets included in the transac-tion are riverfront terminal facili-ties in Nashville for both railroad and barge shipments; a steel dis-tribution operation including facili-ties, contracts, leases and crane and truck equipment, and 20^-acres of riverfront industrial land pro-grammed for a planned industrial park. All of the new operations will be placed in American Ship's Building Material Group and will be integrated with the Cincinnati Sheet Metal & Roofing Division. American Ship already owns and operates terminal facilities on the Ohio River in Cincinnati. "This is an ideal acquisition for us," explained Mr. Kamm. "It ex-pands our terminal operations, gives us greater steel handling fa-cilities and permits future expan-sion of building materials manu-facturing in the Nashville area." SNAME Pacific Northwest Section Hears Paper Describing V.S.P. System On Lake Ferries Principals at the Pacific Northwest Section, SNAME, meeting in Victoria, B.C. were, left to right: M. Markey, chairman; T. Gilbertson, author; F. McLean, holding model of one of the ferries, assistant deputy minister, B.C. District of Highways; John Case, author, and Jacques Heyrman, chairman of the British Columbia area of the section. Two unique car-passenger ferries for operation on the Arrow Lakes of British Columbia, Canada, were described in detail at a recent meeting of the Pacific Northwest Section of The Society of Naval Architects and Marine Engineers. The paper, entitled "Two V.S.P. (Voith Schneider Propulsion) Pro-pelled Car Ferries," was presented by John N. Case, president, and Tom Gilbertson, construction su-pervisor, Case Existological Lab-oratories Limited, Victoria, B.C. 54 Maritime Reporter/Engineering News
