A Better Thin`g "Ws! foWrpWB*''e tter Living , , through Chemistry New England chose "DULUX" for this office on wheels Interior of converted bus is comfortable yet businesslike. Company uses "Dulux" on its regular fleet of trucks, buses. Bus, converted by W. F. Lacey and Sons Co., toured dew England cities last year. Here Worcester mayor, center, greets N.E.T. men. Durable "Dulux" enamel keeps this rolling office of the New England Transportation Co. tops in appearance. Since the converted bus is the showpiece of the company's transportation fleet, appearance in this case is mighty important. Brain child of Pierre "Spike" Dumaine, company president, the hus-tumed-office boasts interior wood paneling, a radio telephone, built-in TV set, range and refrigerator. Company executives drive up to a customer's door in it. Says one: "When you invite a man inside for refreshments and a talk, he's away from the interruptions of his own office. It's not just a gimmick; it serves a practical purpose." Turning a 15-year-old transit bus into the handsome vehicle you see here was the work of W. F. Lacey and Sons Co. of Medford, Mass. "Dulux" enamel, chosen for its brilliance of color and outstanding wearing quality, was used on the exterior. The office-bus made a grand tour of New England cities last fall, winter trips to the area's ski regions, and a spring junket through the Middle Atlantic states. Most of the time it was parked outdoors. Still the finish is almost unblemished, and, thanks to dependable "Dulux", will remain that way through many trips to come. <M>DUUI REG. U.S. PAT.OFF.

McCORMICK When the Company announces a new product, acquaint ances of Du Pont might be Inclined to ask, "How does it fit into the over-all Du Pont pattern?" In the ease of silicon, they might have asked the question more pointedly than usual. What was a chemical company doing refining this semimetallic element? Yet, like sodium, titanium and other metallic and near-metallic elements well mention later, silicon fitted snugly into place at Du Pont. There was :an-acute -need for the element, research was active silicides with pigment possibilities. Sounds simple, but the curds were stacked against than. There was no such thing available as-pure silicon, and, thus, through basic research in the pigments field, Du Pont found itself trying to make the element itself. World War II suddenly made the silicon tail more important than the silieide pigment dog. The word was passed that a purer silicon would-help 'the armed forces with a new thing called radar, and couldn't -wo help?

'..... Precious metals have their day, too. For decades, Du Pont has made formulations of precious metals for decorative purposes. The gold on your dinner plate or glassware, for instance. Research in this field is primarily of the product-improvement variety, designed to make a coating that will be easier for the manufacturer to apply and will be better looking and more durable for the eon- ' sinner.''

In a roundup article of this type, we can't cover re search on every Company product allied to metals. A major field of our endeavor is in protective metal finishes, but a single example of this research must do. During the Depression years, when Du Pont was just as concerned with doing research as it is in good times, R.T. " Hucks"of"Finishes- research- conceived "the' idea ofcombin.Jngr.in..a..la.cquer,..partM8s....ol.;m.efal..I:ie...altmini!ni...K.itli...dnr-..;. able pigments, such as fine;particles of green chromium oxide.

These auto finishes have! brilliant highlights and dark, deep tones in the shadow areas. Metals research plays its part in Company explosives, too.

MACKEY llur GrasseHi Chemicals Dept, informant positively glowed while describing the use of lumber treated with chromated zinc chloride on offshore oil drilling platforms in the . Gulf of Mexico, ' "Textile mills in tire CarGliias" he added, "can give you another side of the story--the almost unbelievable num berofyears CZC treatment has added to the life of lumber.". ' To follow up these leads, we first visited Houston's oilmen to learn about offshore drilling in general and the value of Du Pont Chromated Zinc Chloride in particular. Here we found the same enthusiasm, only it was more vocal. At 'Continental Oil's headquarters, we talked to James C, Craig, superintendent of marine development. Offshore drilling platforms, like the one pictured here, are being built by Continental and other oil companies in many areas of the Gulf. Each is worth a small fortune, costing up to $400,000. ;; "Lumber for the rig decking, or platform floor," 'Craig-said,."is -m~: danger of -being met-afire by welding sparks, so our decision to use lire-retarianf wood was a natural one. We asked the advice of the engineering firm of Brown 8s Boot, who recommended CZC. That, too, seemed ' a natural, for we like other features of CZC-tieated lumber --rot resistance and freedom tooth from vapors and a ' slippery surface during hot Gulf of Mexico' summers," from F. R. Haulier, designing engineer of Brown & Root Marine Operators, Inc., we learned more on the subject. "From the competitive point of view, wood is the best structural material for oil platform decking. This is despite the fact that the Gulf dampness rots wood, and drilling muds attack it. '. "By treating with CZC," Hauber said, "we can stop rotting and make wood much better able to resist fire with out reducing its strength1 car other good features. We built a platform off Galveston' in 1948, and its CZC-treated decking is still in good shape.: Since first specifying the ..iie'oF'Di.Foil.CErinillwi.Zinc.CMoHili""in.*47,.we've A final stop in Houston took us to the treating plant where a solution of GZC had been forced under heat and high pressure into wood for the decking. In addition to doing such work for industry, this company, like a majority of wood preservers, carries on hand a stock of impregnated "Preserving wood in this Gulfregion has always made good sense," they-explained. "The-heat and humidity here are Heal for termites and rot. In recent .years, treating has become even more necessary because virtually all lumber in the country is sapwood from second- or third- needs to be treated.to make up the difference.

Copy cards informed them that the coal was Famous Reading Anthracite, and that anthracite black with a touch of red was a style note of the autumn season. Promotion of coal in store windows may seem unusual, but it's only a sample of the vigorous merchandising adopted by The Philadelphia and Reading Coal and Iron Co. Like the rest of the anthracite industry, Reading's sales efforts are aimed at capturing new markets for hard coal and winning back markets lost to competing fuels. The little red spots on the coal loom large in the company's merchandising program. They are an easily identifiable trade-mark, established in the public mind by 15 years of promotion. The company feels that the trade mark and the slogan, "When it's red, it's Reading," have become symbols of anthracite quality to consumers. Reading registered its red trade-mark in 1928, but technical difficulties slowed its adoption. Colored wood pulp, one of the early materials sprayed on the coal, turned purple on exposure to weather. Other trials were little more successful. Finally, in 1939, Philadelphia and Reading took its problem to the Du Pont Finishes people, who developed a special red paint for the job. The identifying "red for Reading" paint has to meet several specifications: It must be inexpensive to use, must stick to the wet surface of freshly washed coal, and must dry quickly so that the red spots don't become red smears. The spray nozzles that apply the paint at the breaker have to be specially adjusted, too. They must splutter rather than spray to achieve a spotting effect. "The high quality of our product and the signifying red trade-mark are our biggest assets," a Philadelphia and Reading spokesman told us. BEDROOM SET--drapes and bedspread feature new Fiber E-cotton combination. FIBER E RUG--it's practical, and the crimp stays through repeated washings. UPHOLSTERY--luster of crimped Fiber E Rayon is outstanding. rayon with a uwave*>r> Fiber E Rayon is another Du Pont contribution to luxurious and practical modern living. Its "wave," or unusual curl, actually improves with trashing and gives it long-lasting beauty. Shown here are some of the modern, practical products being made from Fiber E by textile manufacturers. We say practical, because Fiber E launders easily and doesn't lint or lose ils luster.
