Power Factor Savings With

Energy Efficient Motors

A new generation of premium quality energy-efficient motors with power factor correction to 95 per- cent has been announced by Reli- ance Electric Co., Euclid, Ohio.

Highly efficient and compact ca- pacitor technology provided by Re- liance Electric Company's affiliate

Cornell-Dubilier Electric Corpora- tion, offers the capability to in- clude power factor correction ca- pacitors as an inherent part of the motor circuitry on the Reliance

Electric Duty Master" XE energy efficient A-C motor product line.

Designed to provide a full load power factor of approximately 95 percent, these motors will deliver both kw and kva energy savings.

Capacitors are mounted inside the motor conduit box and exter- nal indicating lights provide posi- tive indication of functioning ca- pacitors. A terminal connection block is provided in order to sim- plify motor installation and pro- vide ease of capacitor replacement.

The XE/IPF A-C motors are engi- neered for rugged marine, mill and chemical plant environments and are suitable for both indoor and outdoor service.

Available in ratings 15 horse- power through 350 horsepower, the IPF (Inherent Power Factor) feature is offered as a standard op- tion on production, as well as stocked XE motors.

Anderson Moves To

AAPA Chairmanship

Lloyd Anderson

Lloyd E. Anderson, executive director of the Port of Portland, became chairman of the American

Association of Port Authorities (AAPA) at its 72nd Annual Con- vention in Seattle, Wash., Septem- ber 11 to 16.

AAPA represents the interests of some 176 seaports in the West- ern Hemisphere before various governmental bodies, including the

U.S. Congress.

Mr. Anderson has served as president of the Institute for

Transportation of the American

Public Works Association and was named by that organization as one of the top 10 public works leaders in the country last May during

National Public Works Week.

Burrard Yarrows To

Build Two Icebreakers

For Can. $108.5-Million

Burrard Yarrows Corporation of

Vancouver has received an order from the Canadian Government to build two Type 1100 Navaid/Light icebreaking vessels at a total cost of Can. $108.5 million. Construc- tion will begin early next year.

The icebreakers are to be con- structed at the Burrard Yarrows yards in either Esquimalt or North

Vancouver, commencing in March 1984. Each vessel will create 400 person-years of work, with deliv- ery of the first vessel to take place on October 1, 1985 and the second on January 15, 1986.

The principal characteristics for this new Coast Guard icebreaker are: Length 83.00 meters; Breadth 16.20 meters; Depth 7.75 meters;

Displacement 4,662 tons; Horse- power 8,445; Speed 15.3 knots;

Range 6,500 Nautical Miles at 15 knots; Crew 52.

The ships are to be equipped with twin-screw diesel electric propulsion and the hulls will be suitable for icebreaking purposes as Arctic Class II vessels.

Michigan Wheel nozzle:

The state of the art.

Concentrating solely on refining propulsion technology for over 79 years has given Michigan's marine architects the expertise to develop open and ducted propel- lers with proven performance, speed and dependability.

THE MICHIGAN WORK-HORSE

The 4-blade Work-Horse, with its thick machine-pitched cross-sec- tions, runs noticeably smoother than the 3-blade props it replaces.

The extra blade area also makes it ideal for installations where clearance is limited. Designed particularly for hard-working tugs and pushboats, its heavy-duty leading edges are rounded for greater abrasion and fracture resistance. Corrosion is a mini- mal concern because it's cast in either Michalloy-K bronze, Ni-Bral or CF3 mod stainless steel alloys.

MICHIGAN NOZZLE

SYSTEMS. When Michigan

Nozzle Systems—which feature Kaplan-style blades- are compared to open props, they deliver more thrust with equal power, or com- parable thrust with less power. Fuel savings have been reported up to 25%.

Bollard thrust increases from 40% to 50% are also common. Thus, the logic for retrofitting with a Michigan

Nozzle System becomes obvious: When operational costs go down, profits go up.
