Illinois Tech Graduates Women in Chemistry War Course

TLLINOIS INSTITUTE OP TECHNOLOGY graduated 24 women in an industrial

chemistry war-training course on August 22. The course is part of the institute's Engineering, Science and Management War Training program, and the women are going into war work immediately. Illinois Tech was the first school in the Nation to offer such courses training women for technical war jobs. Other sec­tions in industrial chemistry will be opened later, as well as courses in ordnance inspec­tion and industrial drafting—the other courses which arc offered in the program.

Published under the Auspices of the Rubber Division of the American Chemical Society

N O T E : The prospect of a severe and long-continued shortage of rubber makes it more necessary than ever for the industrial consumers of rubber to under­stand its properties. Such knowledge will greatly aid them in determining what substi tute materials can be used to greatest advantage.

This book is designed for all those connected with t he rubber industry, whether research workers, analysts, compounders or development engineers. It is an author i ta t ive reference work for both the theorist and the practical man.

Outside the rubber industry, this Monograph will prove invaluable to students, and t o research and development men in numerous in­dustries which supply raw materials for the manufacture of rubber goods. Engineers in the petroleum and chemical industries, on whom the responsibility of stepping up synthetic rubber production will now fall, will be greatly helped by the chapters on the physics of rubber and on substitute rubbers. Finally, this book will be useful to large-scale consumers of rubber: to textile plants, which now employ latex extensively; to the footwear and clothing industries; to au tomot ive and other mechanical engineers; and to industrial maintenance engi­neers everywhere, who have become dependent on mechanical rubber goods for factory and field installations.

CHEMISTRY AND TECHNOLOGY OF

RUBBER

Danish Glass Works Resumes Operations KESI^MPTION of operations by the glass works at Kersor, Denmark, after two years' idleness because of lack of coal, is reported officially from Denmark.

The plant has a capacit}* to produce a considerable part of that country's re­quirement, approximately 6,000 tons annually, and has been put back into activity because stocks have become exhausted and the demand has risen. Some 7,000 tons of coal have been as­signed to the factory. Stocks of other raw materials are said to be adequate.

It will be several months before the new Danish glass is on the market, it is stated, as the ovens must be fired, and the initial product is likely to be defective.

Recovery of Steel Plant By-Products Planned in Brazil 1 HE Brazilian Government expects to recover large quantities of chemical by-products from operation of a steel plant being constructed in that country. The plant should be in full operation by the end of 1943. Estimated by-products will be tar, 15,200,000 liters annually;

benzene 3,880,000 liters; toluene, 896,000 liters; solvent naphtha, 93,000 liters; ammonium sulfate 5,200 tons.

Resistance to Heat, Fatigue Increased in New Alloys

U O U R aluminum alloys of beryllium, said to retain their high tensile strength

even when subjected to the high t em­peratures encountered in the newest air­plane engines, have been developed b y the Aluminum Co. of America, New Ken­sington, Penna. The alloys are revealed in Patents 2,286,624 to 2,286,627, granted to Lewis W. Kempf and Walter A. Dean o f Lake wood, Ohio. I t is claimed that t h e new alloys are not weakened by tem­peratures as high as 600° F.

Arginine (To be sung to the tune of "Tangerine")

A R G I N I N E — i t ' s got guanidine. In the liver i t gives rise to ornithine. Arginine—it yields putrescine. Also known as tetra methylene diamine. There are those who say arginine, Hasn't got a lot to do with creatine. Now I don't intend to be mean— But I'll say this for creatine, It's amidines from arginine.

"Dry" Bans Alcohol Tires A TELLING point against alcoholic rub­ber is pointed out by the New York Times in quoting a "letter to the editor" from an ardent prohibitionist of Nashville, Tenn. He said, "Fellow prohibitionists, let us refuse to use this product of an evil in­dustry in any way, shape, form, or fashion, as we have in the past. We had rather walk than ride on tires made of alcohol."

FLUORESCENT BALANCE IAMP

directed Frontal Illumination Mounted at the iront of the balance case,

the paz-aholic reflector directs all light over the entire working area of the balance.

The lamp is rigidly supported by a clamp which cannot mar the case finish, can be at­tached to all makes and styles of balances, and wfcien in position permits free movement of the sliding· door. The weight of the re­flector is greatly reduced by making a separate unit of the auxiliary so that it can be placed on. the laboratory bench close to the balance. The G. E. fluorescent tube supplied with the lamp produces approximately 750 hours of g-lareless, efficient light of daylight quality. S-3820 Balance Lamp, Fluorescent, Sargent.
