are replaceable
Announcing NATSYNB 400 polyisoprene rubber-the one economical total replacement for all but the lowest grades of natural rubber. Replace freight and pier charges . . . the rate/cwt from New York to Chicago, for example, on a minimum truckload of M R S S is $1.10. NATSYN, no charge. Replace excessive handling and processing costs . . . natural rubber comes in 250-lb. chunks-bulky, hard to handle and store. NATSYN 400 comes in 75-lb. bales-unit containers on wooden pallets; polyethylene-wrapped bales in 5-ply paper bags (loose or unitized on pallets);
bales in 5-ply silicone-lined paper bags (loose or unitized on pallets). NATSYN processes faster than natural rubber. Needs no cleaning, guillotining, testing or mill breakdown. Can save you 2 to 4C Ib. in handling and processing. Replace shipping delays , , . Far East situation makes natural rubber supply uncertain. Delivery can take months. NATSYN can be delivered within 24 hours in prime rubber markets. So you never have to stockpile in anticipation of higher natural rubber futures. Or revise production schedules. Replace color variations . natural
..
rubber changes from lot to lot. The color of NATSYN 400 is equal to 1 X pale crepe. And consistent from batch to batch. Replace irregular cure rates . . . natural rubber cures are inconsistent, require constant testing. NATSYN 400 has a reliable, uniform cure rate. Replace rubbery odor . . . NATSYN odor is negligible. Won’t contaminate end products. Replace natural rubber . , , send for an evaluation sample of NATSYN 400: Goodyear Chemical Data Center, L-20, Box 9115, Akron, Ohio, 44305.

An ILLCO-WAY IonXchanger can be delivered to your plant completely assembled just the way you see it here -usually at lower cost because the assembly is all done in our own shop by our experienced people. SHIPPED ASSEMBLED
Such an IonXchanger is ready to go to work in very short order after arrival. Hook it up to inlet, outlet, drain, and electric power, put the resins (correct quantities furnished) into the tanks and you are in business. SHIPPEDASSEMBLED
Contrast this with piecemeal delivery of parts, field assembly by local help, or contract assembly at higher costs. The ILLCO-WAY method offers you a piece of equipment that has been completely assembled and checked before leaving our factory. The only minor disassemblies after that are of breakable parts such as flow rate indicators. In addition, we can furnish, in advance, accurate dimensional locations and sizes of all necessary connecting points. SHIPPED ASSEMBLED
Such a unit can be packed in several ways. It can be boxed, or it can be crated, or, if conditions are suitable, it can be set on a truck and delivered ready for skidding into position. The best method will be selected for each situation. SHIPPED ASSEMBLED
The IonXchanger shown above is a twobed, automatic , unit delivered to an Eastern power plant, for service at 200 psi working pressure. If you are interested in this or anv other kind of ionexchange equipmen't, write or telephone Mr. A. W. Michalson at ILLINOIS WATER TREATMENT COMPANY, 840 CEDAR ST.,ROCKFORD, ILL. 61101.

Mail Coupon for TAM’S new Paper, “ZIRCONIUM CHEMISTRY IN MODERN TECHNOLOGY” It‘s vital reading for forward4ooking executives and chemical engineers. There’s a lot of zirconium in nature, but technology has scarcely scratched the surface of the opportunities afforded by its unique properties and chemistry. For example, it forms both complex anions and cations.. it “ties” together diverse molecules in amazingly strong chemical bonds. ,.it promotes the effectiveness of other materials in reactions in which it does not itself enter. The intriguing properties of zirconium offer almost unlimited potential for modern technology, and remain only t o be exploited by forward-looking research, development and production men. We invite you t o send for this new Paper that pre. sents some fundamental properties of the zirconium atom and compounds, as well as applications and procedures. It may open new doors for economically improving the quality and performance of your present and future products and processes.
