Yes, Wyandotte is rushing its$25,000,000 expansion program to provide more of the chemicals you need DON'T let these pictures fool y o u ! T h e y were taken early last July —and we've b e e n mow-*r fast since then. We're going FULL SPEED AHEAD on o u r h u g e e x p a n s i o n program to p r o d u c e more alkalies, more chlorine, synthetic detergents and glycol products. It's a big j o b — b u t it's moving right along. T h e tremendous demand for some Wyandotte Chemi cals still exceeds o u r production. But the day i s c o m i n g w h e n we'll have e n o u g h of everything for everybody. Meanwhile, we're allocating t h e available supplies as fairly as we know h o w . Why not l e t u s know your needs? We'll do o u r best t o fill them.

O T S Reports Copies of the following reports can be obtained at the prices indicated from the Office of Technical Services, Department of Commerce, Washington 25, D. C. Orders sliould be accompanied by check or money order, payable to the Treasurer of the United States. The details of German textile develop ments designed to increase the strength of viscose fibers, to spin two fiber substances simultaneously and t o dehydrate moist synthetic fibers, are now available to the American textile industry. The Germans claim to have produced synthetic fibers with increased dry and wet strength by coagulating viscose in zinc-containing, weak acid baths, stretch ing the threads in a hot weak-acid bath and then decomposing them to cellulose hydrate. The baths, composed of 4 to 10% ammonium sulfate, sulfuric acid, and other commonly used salts, contain only 3 % zinc sulfate. The strength-increasing treatment produces fibers as strong as those treated with three or four times the quantity of zinc sulfate, reduces clogging

to holes in the spinnerets, and increases the spinning periods. Stretching and decomposing the threads which consist partly of cellulose xanthogante are carried out in water at tempera tures in excess of 70° C. The weak-acid condition of the water is produced by the coagulating liquid which adheres to the thread or by adding 1% of acid to the bath. Two formulas and spinning direc tions for viscose containing 8% cellulose and 6.5% alkalies are included in the re port. Orders for translated copies of PB 31,528 (Process for Manufacturing Viscose Fibers of Increased Dry and Wet Strength; mimeographed, $10.50, 5 pages), P B 31,532 (Spinning with Double-Bottom Spinneret; mimeographed, $17.50, 9 pages) and PB 31,542 (Continuously Op erating Hydro-Extractor; mimeographed, $14, 6 pages) may be obtained from Re search.

Remote speed control is said to be ac complished by use of a flexible cable shaft up to 10 feet away from the motor. For complete remote control, a small pilot motor can be used to drive the speed con trol mechanism.

Lewis (Continued from page 2814) Chemists' Association, the Chemists' Club of New York, the Engineers1 Club of Boston, and the National Academy of Sciences. H e is an honorary member of the Institute of Chemical Engineers (Brit ish). This year Princeton University bestowed upon him the honorary doctor ate degree. He was recipient of the Perkin Medal in 1936. An intimate of Lewis states that while the doctor cherishes the honors which have been bestowed upon hixn, >>i« greatest pride comes from the achievements of men who have studied aad worked under him. "Doc"—as Lewis is known t o hie associates—is fond of hiking and habit ually takes a long brisk walk after lunch and after dinner. A favorite vacation pastime is mountain climbing, especially in the company of his grown-up children. Lewis was married in 1909 t o Rosalind Denny Kenway. They have four children and two grandchildren, and live on Lom bard St., Newton, Mass., not far from the scene of his boyhood chores. Doc and Mrs. Ijewis took two English children into their home for the duration of the war. He has served as a deacon in his church, and for many years has taught a Sunday school class of boys. As a token of affection, one of the classes pre sented their "Doc" a 20-inch slide rule. 2865
