Atlantic-Pacific Mfg.

Named Distributor For

Mitsubishi Life Rafts

Atlantic-Pacific Mfg. Corp. has been designated the exclusive North

American distributor for the Mitsu- bishi Inflatable Life Rafts, which will supplement its line of rigid life floats and other flotation equipment.

Atlantic-Pacific Mfg. Corp. of 124

Atlantic Avenue, Brooklyn, N.Y., is the manufacturer of the nationally known brand of APCO marine life- saving equipment and is the oldest manufacturer of flotation equipment in the United States.

These rafts are available in 4, 6 and 8-man capacity and packed in either a neoprene valise or fiberglass container. The SOLAS type is avail- able in 10, 15, 20 and 25-man ca- pacity.

The Mitsubishi self-inflating life rafts for use on deepsea shipping or coastwise vessels conform to the con- ditions set forth in the International

Conference on Safety of Life at Sea 1960 (SOLAS). 7of the last 10 tankers built in the

U.S. use Norriseal butterfly valves.

Equitable Delivers Four Watertaxis

For African Offshore Oil Operations

Equitable Equipment Company, Inc., New Orleans, La., shipbuilder, has delivered the four new high-speed watertaxis shown above for work in West Africa's offshore oil fields.

The vessels, 32-foot personnel launches, were built by Equitable for Suthercraft Ltd., Port

Harcourt. They are each powered by a single General Motors 8V7IN diesel engine and have top speeds of 25 miles per hour. The new boats were shipped from New Orleans to

Port Harcourt via cargoship. Equitable is a wholly owned subsidiary of Trinity Industries.

The reason is Norriseal quality. Norriseal valves are extra rugged and dependable—built to outlast other valves and require less main- tenance. They provide positive shut-off time after time with 360° disc sealing and handle working pressures up to 200 psi.

Norriseal design insures long, leakproof operation. O-ring shaft seals, separate from the seat, prevent leakage from the valve bore, lock in lubrication and make replacement of both the seals and the seat easier, faster and lower in cost. Replaceable body O-rings provide end seals and eliminate the need for flange gaskets.

Norriseal offers variety as well as quality. We make valves in sizes from 2" to 28" with manual or automated operators. We offer a variety of body and disc metals, including bronze and a large selection of elastomers. 'Cleveland' Name Board To Kings Point

Zink, Orient Overseas Line; Victor Shen, vice president, O.O.L.; Capt. Carl Larkin and

Rolfond Fay, American President Lines, San Francisco; John Hsia and James Liang,

O.O.L., San Francisco.

When Orient Overseas Line re- cently purchased the famous S/S

President Cleveland, her name be- came the S/S Oriental President.

Orient Overseas Line donated the old name board to the collec- tion of the U.S. Merchant Marine

Academy at Kings Point, N.Y.

Capt. Joseph F. Corcoran, USMS, the Academy's Western Region

Representative and a Kings Point alumnus, class of 1943, accepted the historic memento from Victor

P.S. Shen, vice president of Orient

Overseas Line, and Capt. Carl Lar- kin, assistant director offshore op- erations, American President Lines, the ship's owner for 25 years.

N.Y. Metropolitan SNAME Hears G.E. Authors —Nominates Officers For 1973-74 Season

Pictured at the New York Metropolitan Section meeting, left to right: I. Hilary Rolih, chairman, papers committee; Robert D. Markhoff, General Eleotric Company; Nicola F.

Pergola, executive committee; B. Siegel, John W. Mann and M.A. Prohl, authors, and

Charles W. Wilson, chairman of the Section.

The New York Metropolitan

Section of The Society of Naval

Architects and Marine Engineers met on March 13 at The New York

Times Building, 229 West 43rd

Street, in New York City.

After a social hour and buffet in the Executive Dining Room, the technical session was held in the

WQXR Auditorium. The paper presented was "Improved Turbine

Operation by Drainage of Steam

Systems and Monitoring of Vibra- tion," by J.W. Mann, M.A. Prohl and B. Siegel, all with the General

Electric Company.

This paper reviews recent opera- tional problems caused by water induction into propulsion turbines and the resulting heavy vibration.

The phenomenon is described as an orbiting vibration of the turbine shaft. Analysis shows the condi- tions required to produce this re- sult. The steam system is discussed with a view to reducing the op- portunities for water induction and specific recommendations are made for improved drainage. A newly de- veloped vibration monitoring sys- tem is described which can be used to reduce turbine speed when very large vibration levels occur.

Also during the meeting, chair- man of the nominating committee

E.A. Catlin announced the nomina- tion of the following officers for the 1973-74 season : Donald Carpen- ter, chairman; Thomas J. Sartor

Jr., vice chairman, and Robert P.

Fulton, secretary-treasurer. I. Hil- ary Rolih and Nicola F. Pergola were nominated to the executive committee for a 'two-year period.

Norriseal valves meet all standards and regulations. Norriseal butter- fly valves are manufactured to meet Coast Guard, ABS, Lloyd's

Register of Shipping and Det Norske Veritas regulations, as well as military standards.
