Stow Flexible Shaft

Engineering Handbook

Stow Manufacturing Co. has just published the fifth edition of their 74-page Flexible Shaft

Engineering Handbook for engineers to use in many applications. This handbook contains in- formation on the latest developments on Stow

Flexible Shafting, including the all new .190 diameter standard power drive and remote con- trol flexible shaft. Also included is information on the latest materials used to make flexible shafting for use in high temperature areas.

The Stow Flexible Shaft Engineering Hand- book is divided into seven major sections as follows: (1) basic information on flexible shafts ; (2) core selection ; (3) casing selection ; (4) standard flexible shafts; (5) value engi- neered flexible shafts ; (6) customer engineered flexible shafts; and (7) appendix. In addition, complete charts and graphs are given for select- ing the correct size shaft to suit the job.

ANTI-POLLUTION DEVICE: Colt Industries' Water Pro- cesses Section in Beloit, Wis., manufactures this marine sewage treatment system to control water pollution by ships. This equipment was part of a display at a recent meeting of The American Society of Naval Engineers at the Shoreham Hotel in Washington, D.C. These compact units make any ship self-sufficient in preventing harbor pollution from sewage system discharges. The liquid dis- charge from these units meets current official require- ments for preservation of water quality. The system is an electro-mechanical-chemical module which separates solid and liquid matter and treats each by appropriate methods including incineration. Unlike a biological sys- tem that depends on continual biological action, the unit can be started or stopped as desired. The single module, as shown in the photograph, has a 175-man capacity.

The solids removed from the sewage are reduced to inert ash in an incinerator by odorless, smokeless combustion.

Liquids are chemically treated and the pathologically safe effluent is discharged overboard. This does away with the necessity of emptying holding tanks of refuse when the vessel docks. Several of the modules can be used together to increase the total capacity. Units are available in sizes up to 17,000 gallons of influent per day. Only electric power and fuel oil supply for the in- cinerator are required to operate the units.

FORCE!

That's how little maintenance is required for the ADSCO Type "RJ" Ram-Pak Expansion Joint, now in new designs for greater economy, greater performance. Packing may be injected through ram under full-line pressure. Unitized construction provides integral external-internal guiding of the slip. Stainless steel limit stops on the slip prevent it from being pulled out of the body in case of anchor failure. Send for bulletin information.

Singapore may be half-way around the world from Mt. Clemens, Michigan, but shipowners ii both locations share the busi-ness philosophy that you can't go too far for a good thing. So, naturally they buy deck hardware from NABRIC0 in Nashville, Tennessee. In fact, people in the water transport industry all over the world consider dis-tance inconsequential in buying deck fittings when they're assured the quality construction and experienced en-gineering of NABRIC0 ... whether it's a DF-430 flush-mounted, water-tight hatch . . . winch . . . hose crane . . . locking pin and sock- ets . . . bitts . . . chocks . . . kevels ... or bow steering unit.

So, whatever you need in deck hardware and no matter how far away you are in u'll find we're right over the ir needs are marine. We'd like you how close we can be.
