Hyde Offers Independent

Power Unit Systems To

Meet SOLAS Requirements

SOLAS Regulation II-1/29.20 re- quires that all tankers 40,000 gross tons and over fit an independent means of quickly regaining control of the rudder should a single failure occur in the steering gear piping sys- tem. The deadline for the steering system upgrades is September 1, 1988.

Hyde Products, Inc., of Cleve- land, Ohio, a long-established man- ufacturer of ship's steering gears and other shipboard machinery, has developed a series of independent power unit systems to meet the

SOLAS requirements. More than 60

Hyde IPU systems have been deliv- ered for installation on tankers worldwide.

Hyde offers a series of four stan- dard power units, from 10 to 30 hp, each available in two configurations.

Hyde also offers a variety of cylin- der-mounted "Fast Acting Valves" which can be fitted to any make or type of steering gear. The Hyde IPU system provides a recharging capa- bility if steering system oil is lost, a rudder-locking capability and lim- ited steering capability within 15 degrees of rudder angle. Hyde's

Type "A", two-stage design also provides full rudder torque steering capability to or from the hardover angle without increasing the horse- power requirement. Non-follow up steering control is provided from the steering gear room and, if desired, from the bridge or other locations.

The Hyde systems have been ap- proved by ABS, Lloyd's, the U.S.

Coast Guard, NK (Japan) and Bu- reau Veritas. Steering gears built by most U.S., Japanese and European manufacturers have been upgraded with Hyde IPU Series independent power unit systems. Hyde's highly engineered, efficient design has made its IPU system's price com- petitive in the world market.

SKF Introduces Keyless

Bushing; Will Market

Nilos Rings In U.S. —Literature Available

SKF Component Systems has an- nounced the availability of a new mechanical friction joint, the SKF

SH-Bushing. Also announced by the company was the organization of a new unit to market the Nilos Ring, a metallic seal for bearings.

The SH-Bushing makes it easier to join any hub to a shaft quicker and with less chance of failure than with conventional key joints. The bushing/hub remains infinitely ad- justable radially and axially on the shaft.

The SH-Bushing will not create stress in the shaft, and in some applications, the shaft diameter may therefore be reduced. There is no need to machine keyways and axially secure the joint. Retrofit is another advantage, the quickest

June, 1988 method of repairing a key joint is to simply install an SH-Bushing over the old keyway.

SH-Bushings may be used in ex- treme hot or cold environments and are designed to accommodate the tolerances of cold-rolled, commer- cial grade, unground shafting. They are available from SKF and its dis- tributors in over 70 standard metric and inch sizes.

The Nilos Ring, manufactured by

Ziller & Co., West Germany, forms a direct contact sealing lip with either the inner or outer bearing ring so precisely that performance is never affected. After a short break-in peri- od, a groove is formed in the bearing ring surface that effectively be- comes a miniature labyrinth seal.

Nilos Rings are available from

SKF for virtually any bearing size, type or application. Even sealed bearings are further protected by utilizing the Nilos Rings. All-metal

Nilos rings are also available in stainless steel or brass.

HURRICANE GLORIA

SEPTEMBER 1985

MARINEFAX IS PROUD

TO HAVE BROUGHT YOU

SOME OF THE WORST

WEATHER IN HISTORY.

Hurricane Gloria, September 29,1985. Eighty knot winds and hundreds of boats damaged or destroyed. But some mariners had an Alden Marinefax® weather chart recorder aboard and had prepared for the storm.

For over a decade Marinefax has been bringing you the weather-in advance. Charts that help you plan your course around the worst weather-or into the best.

Over the years, Marinefax has changed with the times.

Today's Marinefax TRI has fully automatic chart reception, and features an exceptionally precise radio which locks onto the frequency, eliminating the "drift" common to most other radio receivers. Our dry-paper charts are big and bright, with exceptional resolution, even in multi-contrast satellite photographs.

At Alden we specialize in the weather-only weather. So each Marinefax is built to the same standards of performance as our professional meteorological equipment. Standards which have won Alden Marinefax seven consecutive NMEA awards for performance and reliability.

For more information on how Marinefax TRI can bring you the weather, contact Alden Electronics, 136 Washington

Street, Westborough, MA 01581. (617) 366-8851.
