SPECIAL REPORT Radiation processing wins fanfare , but surprisingly few radiation-treated products hit the market. The problem: Radiation sources are fairly expensive, and the cheapest—spent nuclear fuel elements—are many years dis­tant. Page 16.

F E A T U R E Textile chemicals have healthy market prospects. Mills and finishers bought $390 million worth of chemicals in 1955, but they form a much larger potential for chemical pro­ducers. Page 124.

I N D U S T R Y Koppers1 new coal chemicals plant is a new con­cept, says company official. Commercial use of coal tar prod­ucts is now limited to those which boil below 500° F.; Arroyo plant aims for points between 500° and 700° F. Page 22. Rayonier gears for intensive research on cellulose. Its new $1.3 million laboratory at Whippany, N. J., boasts latest facilities for improving some of the end products of chemical cellulose-more than 500 in all. Page 23. National Plant Food Institute ups its budget with an eye to bigger fertilizer markets. Consensus is that farmers need to be educated to the profits of increased fertilizer use. Page 26.

R E S E A R C H British researcher studies mosquito repellents, eliminates the human element. He deals only with compounds whose odor repels and may come u p with a general theory to aid in the choice or synthesis of repellents. Page 33.

G O V E R N M E N T Russia's atomic power plans appear overly ambitious in the light of actual progress, says AEC's Davis. Her ability is not to be discounted, he warns, but her new pro­gram looks more and more like that of the U. S. Page 34. Industry braces for possible action on the part of trust-busters. A new report from Senate antitrust subcommittee in­dicates that the 50 biggest manufacturers increased their share of the market from 17% in 1947 to 2 3 % in 1954. Page 36.

M A N A G E M E N T Getting both money and manpower for basic research is a hard job these days. Midwest Research Institute tells how it has succeeded in getting both. Page 40.

E D U C A T I O N Colleges can now buy nuclear reactors at bar­gain basement prices. For smaller colleges especially, reactor cost is prohibitive, bu t the subcritical assembly fills the bill as an inexpensive teaching tool. Page 42. School's out for the Delaware Summer Science Day C a m p — the working idea of the ACS Delaware Section. The camp's 27 members swapped a month of vacation for a round of classes, lab projects, field trips, and plant tours. Page 44.

I N T E R N A T I O N A L Israel could expedite her economic devel­opment if she had low-cost power. This power could come either from Middle East oil or nuclear reactors. Page 52.

AT LAST! A SENSITIVE HEAVY-DUTY

LABORATORY BALANCE AT LOW COST

Π222ΠΠ3 High capacity (up to 6 kg.) is made compatible with high sensitivity in two new all-around bulk-weighing balances by TROEMNER.

MODEL 195-B (illustrated) has a sensitivity of -1 g. , capacity of 3 kg. (7 lbs.), tare capacity of 3A lb., beam graduated to 1 0 0 g., 50 g., or 8 oz.; 8" removable nickel-plated pan. Price $ 9 5 ; without beam, $75.

MODEL 2-89B has .2 -g . sensitivity, 6-kg, capacity, 1 -lb. tare capacity, beam grad­uated to 5 0 0 g., 100 g., or 16 oz.; 9" pan. Price $ 1 1 0 ; without beam, $90 .

Both models offer an easy-reading angled index and pointer, and smart gray-and-black corrosion-resistant finish. Nickel-silver or stainless steel scoops for bulk weighing of dry chemicals are optional accessories.

THESE NEW BALANCES will find constant use in the busy industrial or research laboratory. They are part of the complete Troemner line of quality balances and weights of every class, for every need. See your laboratory supply dealer, or drop us a card for Bulletin 1).

Now you can dry gases drier than dry!

LlNDE Molecular Sieves can dry your gases—air, hydro­gen, chemical streams—more thoroughly than any other commercial adsorbent. They will duplicate laboratory performances—m your plant—under normal production conditions.

Even though your gas stream may already he partly dried, Molecular Sieves will remove the last traces of moisture. Only a small volume of adsorbent is required. The same combination of high capacity and low dew-point is also obtained at high temperatures, u p to 2O0°F.

This is SUPER-drying ! Dynamic performance is shown in the accompanying graph. This superior performance also can be expected at higher relative humidities and at other temperatures and pressures. Of particular sig­nificance in production is the relative insensitivity of Molecular Sieves to incomplete regeneration.

This Week C O N T I N U E D

A C S N E W S Walter J· Bleor receives ACS 50-year member­ship, a tribute from former students and associates. Bloor's membership had lapsed while he financed graduate studies, and the group paid his dues for the missing years. Page 54.

A S S O C I A T I O N S The place is New York City and the week, Sept. 8 to 13. Final program for the 132nd ACS National Meet­ing lists over 1500 papers. Page 58.

P R O D U C T I O N Synthetic mica makers aim at bigger and better crystals and more of them. Last week, Synthetic Mica began processing its biggest melt yet—80,000 pounds -looking for the big ones. Page 110.

H EM 1 CALS Gallery introduces three amine boranes in re­search quantities. Perhaps their most interesting property: their function as selective reducing agents in nonaqueous sol­vents. Page 112.

Ε Q υ ι Ρ Μι E_NI Propellant research gives birth to a lab mixer. Atlantic Research designed one for its special handling require­ments, now offers it to others. Page 114.

B U S I N ESS & F I N A N C E Rubber firms wil l have a good year. Profits from synthetic rubber operations will finance enlarged operations, natural rubber holds steady, and the industry ex­pects upturns in tire shipments. Page 120.
