INDUSTRY number can be doubled if necessary. Cargill says it will now be able to increase its research into animal nutrition, industrial and edible vegetable oils, corn and sorghum hybridization, grain storage microorganisms, use of agricultural by-products, marine design and propulsion, and elevator design. The staff of the new center will direct and supervise field research at Nutrena Mills' new research farm, several hybrid corn research farms, and the company's grain handling research unit.

AEC isn't stockpiling uranium r a w materials, but it does h a v e a lot in process Is
AEC
STOCKPILING uranium?
Not
intentionally, says David F. Shaw, Atomic Energy Commission's assistant general manager for manufacturing. However, he adds, all uranium winds up in stockpiles of either plutonium, enriched uranium, or depleted uranium. These stockpiles, created in the process of meeting defense needs, will probably turn out to be the source of future atomic energy. Rumor has it, Shaw says, that the Government will continue to stockpile uranium until 1966, and some call this program "overextended." They think AEC should curtail uranium purchases to help reduce government expense for the next few years. This is a false impression of the situation, Shaw points out. AEC buys uranium currently only for process feed in its plants; it has no objective so far for building a stockpile of uranium raw materials. To understand where AEC's uranium really is, the processes taking place as the metal approaches ultimate use in the fission process must b e recognized. These processes, Shaw told the Uranium Institute of America, meeting in Denver, constitute the production part of the atomic energy program. They also indicate the whereabouts of the uranium owned by A E C . Shaw accounts for it in: • Plutonium, created a t the expense of some U 2 3 5 , delivered t o the weapons stockpile. • Highly enriched U 2 3 5 also delivered to the weapons stockpile. • Uranium of various enrichments of XJ235 withdrawn from diffusion plants for research, for reactor fuel, and for use under the atoms-for-peace program. • Depleted, uranium, low in U 2 3 5 , from diffusion plants which accounts
for the largest part of the uranium processed. • In-process inventories of considerable size. Uranium "in process" at A E C plants includes the concentrates awaiting solution at refineries and varying amounts of orange oxide ( U 0 3 ) , green salt ( U F 4 ) , and metal in process or in transit between feed material plants. Several thousand tons of t h e uranium are always being irradiated at AEC's 13 large production reactors. A charge for one of these reactors, Shaw says, is several thousand fuel elements. Each element contains pounds of uranium. More tons of uranium are in storage awaiting chemical separation, Shaw says. The waiting period allows highly radioactive products in the irradiated metal to decay before further processing. At gaseous diffusion plants, hundreds of tons of uranium are in equipment and piping. E a c h of these three plants involves about 300,000 miles of piping, a large part of which is filled with gaseous uranium hexafluoride at all times. Shaw says A E C constantly reviews the uranium stockpile question. The commission now h a s firm commitments that will supply all present plant feed requirements. Therefore, he says, the time is approaching when it will b e feasible to buy for a raw materials stockpile if it is deemed important to national interest.

G-E silicone Anti-foam 60 disperses faster, controls foam more economically Rapid dispersion of small, uniform particles o f antifoam material is the key to fast, low-cost foam control. Here the performance of General Electric silicone Anti-foam 60 is outstanding. Anti-foam 60 dispersées almost instantly into minute, uniform particles tixat destroy foam bubbles fast. And with G-E Anti-foam 60 you get maximum b e n e f i t from s i l i c o n e ' s i n h e r e n t f o a m - d e s t r o y i n g action, and get it more economically because only a few parts per million are needed in most foaming systems. If defoaming can reduce your processing a n d filling time, eliminate costly boil-overs or i ncreas^e yomir batch capacity (in aqueous systems), get a free test sample of General Electric Anti-foam 6(0 by m a i l i n g the coupon below. We think you will find, a s many
others have, that Anti-foam 60 is the most economical answer to your problems. For n o n - a q u e o u s
systems—
G-E silicone fluids and compounds are also available for efficient low-cost defoaming of non-aqueous systems. Ask for free samples of SS-66 or SF-96. SS-66 is a low-viscosity silicone anti-foam compound. Typical uses include defoaming during esterification of vegetable oils—as well as in paints, inks, antibiotic fermentation and phenolic resin cooking. SF-96 fluids are available in standard viscosities from 40 to 100,000 centistokes for defoaming all hydrocarbons from light-end gasolines to heavy-end asphalts.

WÏÏVÉMKIQ lUJ Rfl drastically cuts anodizing rack replacement Titanium has proved to be an exceptional material for anodizing rack construction. In typical cases, titanium racks have outlasted conventional materials by as much as 30 tim es. This far outweighs the increased original cost. Titanium forms a thin, stable protective oxide film when exposed to air. Likewise, titanium polarizes readily and forms a protective film when anodized by a direct current in an electrolyte. In addition to offering exceptional corrosion resistance t o electrolytic solutions, titanium retains its currentconducting ability, This saves time and labor ordinarily required for stripping the rack after each use. Mallory-Sharon produces high quality titanium in standard shapes—rod, bar, sheet, strip, wire, etc. This material is being used by several anodizing rack fabricators. We'll gladly supply information that can help you reduce anodizing costs. Please write Dept.N 11.
