Pont chemicals, ..meimdomiyJmted.in............ laboratory and field, help assure safe, abundant food supplies for our exploding population Bv Emil y Hk in k An ample harvest; of vine-ripened tomatoes is a sight that should please most people, whether they grow the succu lent fruits In farm or garden or simply like to eat what others produce. To men in the Du Pont Industrial and BioAemiciib Dept, however, it's a special satisfaction. Ton years ago, a grower considered a yield of ten tons of tomatoes per acre excellent; today he counts on 20 tons and Isn't sur prised If he gets 25. , Improved plant strum, better fertilizers and greater mechanisation- me factors' in- this- remarkable-increase; But a significant share of the credit goes to a Du Pont chemical, 'Mnnzate'* maneto fungicide, first used com mercially on tomatoes in 1951; the material now is all but standard. It's notable for its effectiveness against a variety of diseases, particularly the notorious late blight. This harvest of tomatoes, moreover, is linked to man's age-old struggle to feed himself adequately. For late blight, so successfully stopped today, Is the disease that caused the famous Potato Famine of the 1840's, during which ten per cent of the Irish starved and an equal number fled for their lives. Agricultural chemicals not only are disaster control measures but a form of crop Insurance as well. Although the last decade has been filled with talk of farm surpluses, agriculture actually is much more nearly in balance than some other industries. Without chemicals to safeguard production, ..we would, have to have far larger granaries to store for the year of crop failure, as Joseph did. Boost Production, Trim Costs Today agricultural chemists also are looking hard for ways to lower production costs and thus to get farmers out of the price-cost squeeze, common enough elsewhere but especially painful In this industry. Ways of Increasing production must be sought, authorities point out, because we shortly will face a food problem so huge that, ironically, its very scope makes it all but incomprehensible. Tomorrow's story is outlined in population statistics: By 1980, experts predict that there will be 275 million Americans, nearly 100 million more than there are now. By 2000, there will be twice as many as there are today. Estimates for the world are even more alarming--nearly seven billion by the year 2000, compared with fewer than Three billion today,................................................................ In other words, we have less than 40 years to find ways of filling four billion more dinner plates. U.S. farmers will have far less land by then.

Improved farm management, soil conservation and Increased mechaniza. tion will help boost efficiency. But certainly one of the most important factors is chemistry. At Du Pont, the search for new farm chemicals begins with the testing of new compounds for possible biological activity, "We test them as protectants for seeds, as insec ticides, foliar fungicides, soil fungicides, nematocides, herb icides and plant growth rcgulants," explains Dr. Rayner Johnson, manager of agricultural chemicals research. The agricultural scientist focuses on small worlds in order to solve the problems of the population specialist's large one, A step at a time he learns that a new chemical is effective against one fungus on one plant species at one rate of application in one type of soil under one set of climatic conditions. Hundreds of field tests will be in volved before the compound is registered with the U.S. Dept, of Agriculture for full-scale use against tomato diseases. If It is suspected that the material will work on potatoes, too, the same steps must be retraced. The researcher looks at a map and sees a patchwork quilt: a weed killer registered for use on pineapples In continued toto to 'Itso: Ato'V. 7 ..V Hawaii, sugar cane in Puerto Rico, cotton in the.South, citrus In California, asparagus in New Jersey. Without the satisfactory completion of work by scien tists in two even smaller worlds, however, some of the patches would be missing. Finding a promising pesticide is easy enough; hundreds of thousands of chemicals that may show biological effects are as yet untested. "The greatest single item in developing an agricul tural chemical today is the work required to prove its safety in all respects," says Johnson. Chemicals that look promising in greenhouse tests go at once to the company's Haskell Laboratory for Toxicology and Industrial Medi cine. Scientist:.; (here test them on laboratory animals and send bad preliminary information on approximate lethal dose : A LI) i. A good many materials are dropped straight way as too dangerous for the average person to handle. Haskell follows with "ten-day subacute" tests, which give an idea of the cumulative effect of the compound, and a check for skin irritation. If It survives these, it's cleared for testing In the held. test runs oy me rnousana In 1960, Industrial and Biochcmicals Dept, research men put out more than 6,700 test plots in 13 states. They studied fungicides on apples, celery, cherries, cucumbers, grapes, peaches, peppers, potatoes, strawberries and to matoes; herbicides in com, cotton and soybeans; insecti cides on cotton, tobacco and a variety of vegetables. Such work is painstaking, frequently tedious. A single foliar fungicide test, for instance, may involve 80 plots and 2,000 operations--soil preparation and fertilization, plant ing, cultivating, 12 applications of chemicals in small doses, disease evaluations and yield counts. Produce from such plots m carefully destroyed, since safety to the consumer is not yet assured. If plot work looks promising, Haskell Lab begins 90dny feeding testr mi laboratory mi minis.

In special reproductive tests, rats are followed through three generations. More than 3,300 animals may be involved. Meanwhile, the analytical chemists have been hard at work in another-small world. Before the compound could he made in field test quantities, they had to characterize its structure precisely and determine its purity. Their most exacting task, however, is finding ft way to measure how much residue, if any, remains on the food crop at harvest. Under the 1954 pesticides amendment to the Federal Food, Drug and Cosmetics Act, the Food and Drug Ad ministration sets the safe level of residue that can be per mitted in a food crop. This is a tiny fraction--often onehnndredth--of the amount that has been found to have no effect on laboratory animate. Good agricultural practice, however, may cause even less of the chemical to remain; if so, the lower level usually becomes the legal tolerance.

Pointing out that "creative research has never been more important," he observed that as 1961 began, Du Pont -like most of American industry-faced a formidable paradox. On one hand, the company's 1960 sales had been ' "' higher than ever before; $2,143 million. On the other, 111 . iPC earnings were down from $8.92 per share in 1969 to $8.10 per share. The drop, he said, was due to the steadily increasing pressures of competition, declining prices and higher manufacturing costs.

Says Guy Legault, technical advisor to the City two adjoining Hocks, the cavity, known as "the most expensive hole in Canada," remained undeveloped despite its strategic location and Montreal's postwar boom, Today, the hole is vanishing, covered by an $80 million development known as Place Ville Marie--a whole Planning Dept,, "By 1962, what we call our `new office building core' will have added 8.6 million square feet of floor space since World War II," But even in a forest of construction, a tree Ike the rising Cruciform is the attention-getter. Each of its four city center with a three-block shopping promenade, a arms would be an imposing building in its own right. Yet monumental plaza and a 42-story, cross-shaped office building believed to be the biggest in the British Commonwealth. Designed by I. M. Pei & Associates for Webb and Knapp (Canada) Ltd,, the Cruciform Building will have the Cruciform's design makes It possible to have nearly all office areas within 40 feet of windows, By late summer, the structure will be fully enclosed -sheathed in nearly 800,000 square feet of aluminum and glass. Like 13 other new Montreal buildings, the Cruetform is curtain wall construction: a thin panel "skin* hung on a steel skeleton. Designing curtain wall buildings for Montreal posed particular problems for architects. The city is known for its extremes of weather. In a typical winter, it gets more snow than Moscow; in summer Its humidity and heat re mind New Yorkers uncomfortably of home. Even worse from the architects' viewpoint, the temperature often drops or rises as much as 40 degrees in a few hours. When curtain wall construction started to catch on some live years ago, architects hunted hard for a material to give a foolproof weather seal. The thin, light components are in almost constant motion, heating and cooling rapidly. Du Pont neoprene synthetic rubber was a logical can didate for the duable seals and gaskets. Samples that have been exposed to weather for nearly 30 years still are virtually unchanged. Most Important, neoprene offers the .resilience needed to take wind pressure and thermal ex pansion and contraction without breaking the seal. It also has good resistance to sunlight, ozone, oils and chemicals present on adjoining materials. Neoprene compression seals perform well on the job site, too. Carefully designed and manufactured to the architects* specifications, they arrive ready for rapid in stallation. Workmen with no special skills cun snap them over the panels or insert them into frames. Realizing that the rigors of the Canadian climate make heavy demands on weather stripping, architects are specifying neoprene seals and gaskets of some type in nearly every building. On the Cruciform Building, for instance, there will be 8,400 windows in the curtain wall panels fabricated by Vampco. Ltd., for Canadian Pittsburgh Industries, Ltd. The preformed gasketing around the single, quarter-inchthick glass plates is U-shaped, installed right on the job. But rubber firms and fabricators are also molding a variety of other seals and gaskets specified by architects. All told, an estimated 794,000 feet of neoprene--about 150 miles-- will be used to keep out the weather. The 14-story Prudential Assurance Co, Building, (hough iinl fill kiln wall, still has 512 windows a have (he second floor, Kaeh is complete willt neoprene thermal breaks and weal her stripping on sash and frame, adding up (o 37,(M)!) linear feet seven miles of neoprene.

The answer was, "Some other time. Dee." But like any resourceful teen-age daughter, Dee soon changed the decision to "Okay." Furniture was switched, a color scheme devised, and a trip made to the paint store. Early one Saturday, Dee started to paint. The progress of her day is shown in the pictures on these pages: a smooth paint job, only one roller dropped on the floor, easy cleanup and no ruined clothing. The "Lueite" wall paint Dee used is a new acrylic emulsion paint DuPont is Introducing on a national scale this month after highly favorable test marketing in the Philadelphia area and several other cities. It's the latest of the so-called latex paints. In these paints, the film-fanning synthetic resins are dispersed in water instead of being dissolved in mineral spirits or turpentine. Latex paints spread readily, dry quickly and can be retouched without brush or roller marks showing. Mayonnaise? Baffling , . , When a consumer opens Ms first can of "Lueite" wall paint and sees a creamy material almost as thick as mayonnaise, he is likely to be baffled by directions on the label that recommend no thinning and no stirring. Re assurance comes during application, when a blob of the paint quickly flows into a smooth, uniform film without pull or "drag" on the brush or roller. There is none of the dripping or splattering which normally accompanies such a job. No paint runs down the handle onto hand or sleeve, even when the brush or roller is applied to a ceiling. Many of the new paint's advantages are gained through a property known as thixotropy-a characteristic that causes a paint to lose body during application. Because of the motion of the brush or roller, the viscosity (thickness> of the paint diminishes, and it flows out into an even finish. A "self-priming'' paint, "Lueite" adheres well to almost any clean surface, requiring no undercoat even on speckled areas. It is free of the pungent odor often as sociated with oil-thinned paints. Lite other water-thinned paints, "Lueite" is ex tremely easy to remove before it dries. Brush marks on the baseboard or molding, or smears from a brush acci dentally dropped on the floor, can be whisked away quickly with u wet sponge or cloth. The paint also is easy to remove from most clothing with a wet rag and a Utile detergent. If there are missed spots or "holidays" on the painted surface, retouching can be done quickly with assurance that the paint added will spread evenly and blend perfectly with surrounding areas. Brushes, rollers and other equipment can be washed in soapy water. The new coating also offers several notable advan tages over previous wall paints in appearance and durabil ity. Among these are extremely low sheen (flatness), out standing color uniformity due to the even and stable dispersion of pigments, and long color retention. The new wall paint, for all its advantages, dees not eliminate the responsibility of the painter for proper sur face preparation and careful application. While "Lueite" can be used on almost any type of surface, the surface must be dean. No paint adheres well to a dirty, greasy surface. But "Lueite" greatly simplifies the task faced by home painters about to launch interior decorating projects.

Held upright, the spray container sends hair spray, suntan lotion, insec ticide or whatever through a soda-straw-shaped dip tube. When the container is inverted, the slider of "Delrin" moves, opening a new exit route that keeps the propellent in place behind the material it's supposed to push. Because it's highly resistant to organic solvents, "Delrin" replaced brass in this assignment. It keeps com pany with several other plastic parts that are notable for their tiny size and intricacy.

Then, know-how about intricate mold ing and proper attention to the process. Finally, good materials of unvarying quality.

Robert Faust, operator of the Colonial Hug and Car pet Company in Edgemoor, Del,, smiles reflectively. "No doubt about It; when a woman conies into the store looking for a carpet of a certain color she means exactly that-a certain color. With a woman, red Isn't merely red. It's either a `brownish red* or a `bluish red* or maybe even a `reddish redd Sometimes, I think, the lady hopes I have some sort of magic palette and can mh up her `certain color* and give her a custom-dyed carpet right on the spot," Faust chuckles, "And texture? You'd think the housewife plans to spend the rest of her life walking on her hands, the way she caresses a carpet before she buys it. It's an inexplainable sort of gesture--something like a man kicking the tires of a brand new car, I guess. She may never touch the'carpet with' her'hand" again, once it's on the floor, but unless it 'feels plush* in the store it hasn't very much chance of getting into her house at all," Faust's comments just about sum up the major con siderations faced by manufacturers and retailers who seek to meet the demands of the carpeting consumer. This feminine color and texture discrimination are prime reasons why carpeting specialists are welcoming a new form of "Orion" acrylic fiber. Carpels of the new staple, called "Orion" virgin carpet acrylic, were intro duced last year by Alexander Smith and C. H. Masland and Sons, Says C, H. Masland, III; "for years we've awaited a synthetic fiber with wool-like characteristics, since we use wool as par. By this measure, we're convinced Orion' is the best of the acrylics and helps ns achieve the finest, most versatile carpet yarn available," "Orion" acrylic fiber for apparel was introduced In I960, but "Orion" tor carpeta-ls a new variation engineered to provide the required ruggedness. It differs from "Orion" apparel fiber as carpet wool differs from cashmere. Carpeting men have always been preoccupied with the color question. Since carpets are generally sold in stock hues, manufacturers seek to provide as many shades or combinations as possible, so that the buyer (women make a majority of the nation's rug and carpet purchases) can find the color nearest to that special one she has in mind. Dyeing carpet fibers can be compared with painting a wall; paint on a white surface gives a much better color definition than the same paint m a dark surface. With dye applied to the brilliant whiteness of "Orion" virgin carpet acrylic, Smith and Masland have been able to produce delicate color blends never before obtainable. Moreover, the colors are fade-resistant; laboratory and field tests exposed carpet samples of "Orion" to sun light for periods up to twice the industry's accepted standard and there was no color change. ' ' The new carpeting's pleasing "hand"' and' plushness come mainly from the fiber's bulk-for an equal weight, there are more "Orion" fibers per pound than there are wool fibers per pound--and from the manner in which manufacturers have engineered the carpet construction itself. Carpets in a wide range of styles and textures are offered by both Masland, which blends "Orion" with wool, and Smith, which combines it with a modacrylic fiber. In merciless beatings administered in laboratory and field studies, the new carpeting has proved itself to be an outstanding performer. It retains its texture despite re peated subjection to rotary brush scouring; standard cleaning procedures, applied promptly, quickly remove traces of shoe polish, syrup, black coffee and ink; it shows only moderate wear after an accelerated stairway traffic teat that reduces wool carpet to unacceptable appearance, R. W. Howison, Smith vice president, says; "We tell our customers that `Orion' carpet fiber is a tested, proven success. That's one reason we've added two more grades of `Orion' virgin carpet acrylic in 1961." 19 the speed of sound and faster than the earth's rotation. Many purposes have been suggested for the B-70: troop transport, reconnaissance, launching platform for space vehicles, 'Proponents see it also ns the forerunner of a civilian transport that could make the Now York-Los Angeles run in 75 minutes. Whatever its destiny in the air, the B-70 already has made engineering history. Its designers boldly called for new production materials and advanced techniques. Re sult; a plane that bridges the gap between today's aircraft and tomorrow's space ships. One of the major difficulties engineers faced was developing skin to withstand the 500'F. temperatures that friction will create on the plane's exterior. They chose stainless steel. To get around the weight problems that single-layer steel posed, they came up with a sandwich panel construction consisting of a core of honeycomb foil between two thin steel plates. Core thicknesses range from one-quarter inch up to three inches. Next the North American men had to find a reliable way" of-holding,,their sandwich together, Their system calls for inserting a layer of another metal foil between honeycomb and panel. Then, in an automatic brazing process, an oven melts the foil to bond the structure. Condition of Cores Checked Finished panels must be inspected with great preci sion to make certain that the brazing foil created a good bond between the skins and the honeycomb core; that cores weren't crushed; and that no contaminants crept in. North American testing specialists use a novel tech nique known as "in-motion radiography." "We attach x-ray film to a panel and then angle it into position in front of our x-ray source, which we have coned down to a silt," explains inspection foreman Wally S, Demining. "Then we move the panel slowly in front of the x-ray tube as we make the exposure. The speed varies .between.one..and..five. feet.a minute." .................... For this exacting work, North American uses Du Pont industrial x-ray films, Types 506 and 510, These films are on "Cronar" polyester photographic film base, which is widely known for its strength and stability. The x-ray films also offer unusual clarity and consistency of emul sion to add to the accuracy and economy of the procedure. The in-motion technique saves significantly on both time and money, Demining reports. By blurring out the brazing layer closest to the x-ray tube, it allows a larger area to be radiographed. Shooting in motion permits greater coverage per setup, too. Once they pass inspection, the honeycomb panels are ready to take their place in the B-70, For this stage in the assembly, North American developed a fusion welding technique that leaves the skin smooth and unseamed. Again inspection is in order. North American's effort is simplified and speeded by DuPont Industrial X-ltny Day Pack Roll Film, which can he handled safely in day light. Packaged in 200-foot lengths, it can he pulled from the roll. like masking, tape as. needed. After .welding, the welding head is removed from its travel mechanism, re placed with an x-ray head and exposure made in motion. The resulting radiographs detect hairline cracks or other equally minute structural weaknesses. Small mat ters? Yes, indeed, says North American. But this is the sort of care that will give the B-70 a dean chance to show how fantastic she really is when she darts skyward for the first time late in 1962.

Behind all this activity is a decision most corpora lions hesitate to make, since it's no small matter for i business firm to nrnko sweeping alterations in its trade mark and official company colors. More than the expend! tare of money is involved--also at stake is the less tanglbli but highly valued asset known as "public recognition o the brand." Characteristically, though, Phillips--cited by Fortum as one of the most aggressive organizations in one of tin world's most competitive Industries--didn't bat its cor porate eyelash when a special study group reported: "Tin colors of our gas stations are wrong.

Having been tile major paint suppliers for Phillips for many years, these men were well aware of Phillips' conviction that "paint is not an expense - it's an investment.'' Conse quently, they lost no time evaluating the job and drawing lip specifications calculated to give the big oil company the most mileage for its new paint dollar. Background for Decision . . . They worked against a background of data gathered over many months by Phillips marketing, advertising and engineering specialists in col la lit > rat. ion with color eon sullants, dealers, jobbers, customers and motorists. Noi only had the studies weighed tin* immediately obvious factors of cost and time but also such abstracts as image association, customer identification, color attitudes and preference, impact, legibility, simplicity, distinctivenous, adaptability and design penetration. Ultimate decision: drop the tail and maroon station colors and the orange and black trade-mark colors for brilliant white and red. Specified by Phillips for the monumental paint job were Du Pont "Dulux" primers, undercoats and finishing colors. According hi Charles W. 1 'alehen, chairman of the Phillips committee charged with coordination of the renovation job, " `I kiiux' is easily applied, thereby helping fo reduce time and cost factors; if meets the exacting color ennsislency standards we prescribe: and it has the high durability we demand of paint prod nets in an investment of this magnitude.'' Regarding the over-ail project, K. B. Adams, board chairman of Phillips, says: "A main part of mir business is, of course, to sell products, dust as we modernize mn plants, streamline our operations and keep our products at top quality to stay ahead in the industry's keen com petition, we have fo keep our 'merchandising look' up Id dale. In flie past, we've done this several times in various ways, hut this is the first lime we've had a major overhaul on so many features of the face we show to I lie public." He adds: "Although sales have been good, Phillips couldn't risk standing pal in Hie highly competitive race fur customers. Therefore the tan and maroon colors simply had to be dropped since they had proved to be difficult: to see at night or at the high speeds of today's turnpike driving. Moreover, population si lifts iu tile suburbs have placed special emphasis on the importance of good service station lighting anil down-the-road brand recognition.

On his back were strapped his bed roll, cooking equipment, and a new elght-by-eight-foot jade-green nylon tent tied in a horseshoe roll over his pack. The three Explorer Scouts, who had been taking tarns breaking down the crusted snow with the snowshoes, finally called a halt and began setting up camp. Within minutes the trio had raised the snug, taut shelter, built a cheery fire, and set snow water holing in a cooking pot. The climatic conditions were extreme, but ideal for the youthful campers, who were putting the new nylon tent through a rough do-it-yourself winter camping test. The new four-ounce nylon fabric, developed by Du Pont in cooperation with Burlington Industrial Fabrics Company, had been announced earlier after an extensive testing program, and the youths were trying it out on their own. The new fabric, woven of Du Pont nylon Type 330, is expected to find favor among the estimated five to ten million Americans who have taken to camping, both as a family recreation and a way to cut expenses on vacation.

During World War II, the Army made available a two-man mountain tent of nylon, but coating and condensation problems (the fabric didn't breathe, and beads of moisture formed on the inside) limited civilian acceptance. Special Combination Weaves . , , Later, designers and manufacturers of custom-built tents developed special combination weaves that elimi nated these problems and did away with special coatings. Spectacular expeditions, .such, as .those made by . Sir Edmund Hillary in the Himalayas, used a nylon-cotton tent fabric successfully, and other expeditions from Alaska to the Andes have since been outfitted with nylon tents of one kind or another. The military also has studied use of nylon shelters in several types of survival gear. The recent development by Du Pont and Burlington now makes available to the general public a nylon tent that's even better than the custom models. Continuing evaluation is being conducted by America's leading tent manufacturers. Lighter in weight than other tent fabrics, the new "breathable" material nevertheless has strength to spare, and a new weaving and finishing technique elimi nates the need lor coatings. Condensation has been re duced to a satisfactory level of acceptance. The fiber also shows superior resistance to deteriora tion usually associated with storage, and to extended exposure to sunlight. The nylon material permits conven tional methods of fabrication, A labeling program also has been Instituted by Du Pont to assure a quality control program available to all tent manufacturers. Sixty-four of the new tents were purchased by the Navy for Operation Deepfreeze, In another rigorous test, more than one hundred tents made of the new fabric were tried out last year at the National Jamboree of the Boy Scouts of America in Colorado. "The tents were tremen dously well received by both scouts and leaders alike," recalls V. J. Gonnella,. one. of the... section leaders .at the Jamboree, He remembers particularly the enthusiasm of the head of the Philippine delegation, "I'm sure he would have purchased all of them if they'd been for sale," Gon nella says. "The resistance of nylon to rot and mildew caused by a hot and humid climate interested him, since these constitute the Filipino's worst tent problem," Among companies offering tents of this fabric tins Spring are Eureka Tent and Awning Co,, Binghamton; Seattle Tent and Awning Co,; Fulton Cotton Mills, Atlanta; Ames Harris Neville, Portland, Ore,, and Denver Tent and Awning, Whether you head for the beach, the national parks or a snow-covered mountain, camping is for everybody, and you needn't be a seasoned woodsman to enjoy it-- especially if your tent is of Burlington's "Easy Livin' " cloth engineered with Du Pont nylon Type 330. provide drainage for the south side of Chicago and as . pollution prevention measure.
