rvbbcr indus A throw rug on a well-polished floor can cause a painful fall. If you have such a danger zone in your home, play safe with Du Pont "Rug Anchor". "Rug Anchor" is a sponge rubber underlay for small rugs. Sponge rubber is naturally non-skid. For added protection, "Rug Anchor" has a specially textured surface that hugs both the floor surface and the rug. On almost any kind of flooring, this underlay helps prevent slipping and creeping. Your rugs look neater with "Rug Anchor". There's no need to stop countless times each day to smooth or straighten a roving rug. Phone your local rug dealer or department store and order "Rug Anchor" now. It is sold in convenient widths that trim to any size rug. <JDP0NJ> BETTER THINGS FOR BETTER LIVING . . .

Formulas for com bin mg' these chem icals with natural and man made rubber to achieve the limper balance ha\'e been evolved over many years. The modern rubber industry began one day in 18Mb when ( diaries (land year carelessly allowed a mix ture of crude rubber ami sulfur to fall on a hot stove in his labiirafory.

(Joodyear reasoned that if the heat were controlled, crude rubber rtuiId he made as tough and clastic as desired. He ban discovered vulcanization. Vulcanized rubber, while it represented a major advance, si ill had drawbacks. For one thing, vulcan ized ion was a time-consuming uroccss. And the rubber, even after lhis leiigthv (re.-t! inenl. was af tacked rap idly by the oxygen in the at:-. t'regress in clearing these I wo hurdles was slow. Chemists sought diligently for a way to hasten the curing process. 'They found that certain metallic ox ides. such as lime, litharge and magnesia,, were modend civ effective hut by no means the final answer. Then in HUM! a I larvard-editcafed scientist named < leorge C ienslager made a startling discovery, l ie found fha!, small amounts of aniline, an oily organic liquid, art :elera led the vulcanization process. This plentiful chemical was even more welcome lo (he rubber in dustry because it also produced compounds that, were stronger and longer Iasiing than those made with sulfur alone. Its one major disadvantage was high Inxic-ily. Researchers, however, bun id that nontoxic aniline derivatives did the job mam Ik ;I ter. ill in >\r MivrbKs i i i ;i ,i> These dorival ive.s were kin to the famous aniline dyestuffs, so it, was logical that 1 )\i Pont, which began manufacturing dyes during World Wai* 1, should turn in 11)22 l,o the product ion of chemicals for the robber industry. In a short time (he ('ompany developed a. line o.l, chemical, accelerators. These stepped up pro duction and reduced costs by speeding die vulcani zation process. For example, al one time it required several hours to properly vulcanize a passenger car tiro: now il takes less than one hour.

(Taiies A. Kraus, who developed the ethyl chloride process for making tetraethyl lead some 60 years ago, is not the man to let retirement interfere with his normal working schedule. He has proved this almost daily since June, 1946, when he stepped down after 22 years as a chemistry teacher and director of chemical research at. Brown University in Providence, Rhode: Island. Today the bearded scient ist, spends as much time in the college laboratory as he ever did. and university odicials admit thru., putting him on the retired list was an empty gesture. At 75, I )r. Kraus can look back on a career which has brought him a full measure of recognition, including four honorary degrees and the Priestley Medal, one of American chemistry's highest, awards. A former presi dent, of the American Chemical Society, lie also holds the Nichols, Clibbs, Richards anil Franklin Medals. 'Phis Hose application to business has not warped his sense of proportion, though. Pie delights in poking Inn at importance, including his own.

But his Rhode Island friends insist that he never stays there longer than a weekend at a time. "Gets restless," one of them said. "He can stay away from the laboratory just so tong, then, back he comes," Dr. Kraus began experimenting with organic com pounds of metals shortly after the turn of the century. He worked first with tin and mercury as a physics instructor at the University of California in Berkeley from 1901 to 1904. He continued the work at intervals through the years, and thus was a logical candidate ethyl lead was distilled off. Within three months they had run the TEL yield up to 70 or 80 per cent. Du Pont chemists, meanwhile, had also been searching lor a satisfactory chloride process, and they recognized in the Kraus technique the answer they had been seeking. Dr. Wiliam S. Calcott, prominent in the Company's research, was sent to Worcester to look into the new process. Within three months Du Pont had adapted it to commercial production. "Dr, Kraus explained very clearly how life method worked," Dr. Calcott said recently, "Until a month or so ago, the basic process of producing TEL had changed very little. He did a thorough job," Defining Kraus solely in terms of TEL, however, is like saying that Newton once sat under an apple tree or that Franklin flew a kite. when Standard Oil of New Jersey looked around for a imm to 11,ekle Iho problem of TEL production 20 years later.

It's n fine Jihety hut you need to knoiv more aluntl shirts and socks thou the yarn they're made froni Wa]king into a store and asking for "'a pair of nylon socks, size (eleven," is like- going to an art dealer and saying. "1 want a painting made with Smith's oil colors.'' Right away, the man asks what kind of picture you want and which, artists you like. 11 all. depends, in short, on what you need. Mxeelkmt ns Smith's oil colors might be, they I.eJI you only one thing: the picture was done with good paint. The same; is true of nylon. It's an exceptional fiber and we've spoken before of its long wear and easy cart!. Rut there's a great (lord more to a garment than the fiber it's mark; from. In choosing garments, fabric construction is es pecially important. Ho (he more you know about it. the better you can satisfy your own requirements. If you want a comfortable material for summer, for example, you need t.o speak up and ask for it. So, to be sure you get what, you want, here are some guideposts to coolness and warmth: To feel, cool, you need a fabric made somewhat like u window screen that is, loosely woven or porous. Then the cloth will lei air circulate freely, so your body can maintain the right l.eni|M.;r;)|:iirc. You feel hot when your skill can't throw off excess lien! and mois ture fast enough. Suppose you want a warm fabric. Now a lightly woven one is warm. But it doesn't, let excess heat ami moisture escape. It's fine if you waul a wind breaker, but in summer word her it's hot.. If you wish to stay warm wilhout being uncom fortable, you can. 'Flic answer lies in yarns spun from short fibers, like springy nylon staple! or wool, A fabric made from spun tiylmi is warm because flu* fuzzy yarns contain mill ions of tiny dead air spaces. This dead air acts as insulation, on l.he principle of the storm window. Although such fabrics keep you warm they don't give you a Turkish- bath feeling. The spaces between fibers have a capillary effect, drawing moisture away from the body h o il can evaporate. Now for the question of quick versus slow drying. 'False men's nylon socks an an example. Hocks made from mullifUa.rm.mt yarn...smooth, virtually end less I 22 J strands dry fast. Thai's because wafer simply runs off (J(< long, smooth fibers, so flint (.here in very little uu)isllire !<;('(. to evaporate when l.h* socks are hung up io dry. I hit .'-.pun nylon, with its fuzziness and dead air sj >nco-e holds moistmv somewhat. longer and doesn't. dry os rapidly. Which typo of socks should you buy? Well, as wo said, you're ).1m* expert. Arc you a traveling man who needs socks that dry ex fra fast? Or are yen a person who likes fuzzy, extra warm ones? It's all up to you. Off on nylon is mixed with silk, rayon, eoii.oti or wool. I'v using" blended fabrics, designers can make new and valuable fabrics that fake advantage of nylon's dura hi lily, light weight and abrasion resist mice. A nylon-cotton sports shirt, fur instance, can bn especially strong. And a rayon-nylon lilou.se usually will give extra wear. Bui. you wouldn't expect, such garments to lie ideal ieal in performance with nil nylon. Bo far we've been dealing with types of fabrics. Textile and garment manufacturers have oilier factors to consider, such, an styling" and workmanship. Whether your nylon garments are cosi ly or inexpensive depends largely on styling. Good workmanship, of course, should go info any gaimeul. You should expeel to get seams that are correctly sewn with nylon thread, and well-finished so they won't ravel Belts, shoulder pads and other accessories should he washable or remov able. Linings mid bindings on nylon articles such as swimming trunks should In* nylon so (I icy'll dry quick ly and give long wear.
