"As you know, Doctor, I esteem ihe scientific method, whether applied to the capture of evildoers or the design of a painting implement. Thus I invite your attention to the part brushmaking science has played in designing `Tynex' nylon bristles to pick up paint, hold it and release it smoothly. "The magnifying glass reveals that these bristles arc both tipped and flagged. The pointed lips and the split ends in crease paint-holding capacity and contribute to the smooth ness of the paint film. Both are clues to brush quality. "Moreover, a brush made with `Tynex' bristles allows one to paint with any finish on any surface. The bristles retain their resiliency, even in water-base paint, and produce handsome results with no annoying streaks. "To sum up, Doctor, a uniform, man-made bristle, plus the skill of brushmaking artisans, is what makes this brush so superior. It's really that simple." <9 TYNEX NYLON BRISTLES BETTER THINGS FOR BETTER LIVING ...

An automat ie suit, sounds vaguely like something a knight, might, don for hall le I I.'.h no!. In l'm-1. a typical automatic wash-a nil-wear suit looks and feels like a conventional siinunerweight suit. Bui t here is a difference. First of all, the labries in automatic garments are made with a high percentage of I )u Font. "1 faeron" polyester fiber. "Orion" acrylic fiber or. in a few cases. 100 pet* cent nylon. Such fabrics are not able for ( heir recovery from wrinkling at certain elevated temperatures, the feature that makes automatic wash-and-wear possible. The garments also are tailored candidly, using lining materials, thread and other components that are stable and sturdy enough to withstand machine washing and drying-. Inside seams are stitched to prevent puckering and edged so they won't ravel and pull apart, it's these things dim distinguish automat ie clothing from wash-and-wear of" file drip-dry variety.

People in those cities will hi* seeing typical produels of American industry t hings most of us accept, wit limit a second though!.- The very ordinariness of the displays is a key to the success of the Ik S. approach. When the American pavilion opened last fall at Zagreb, Yugoslavia, for instance, the main attraction was a full scale, fully slocked supermarket. A stalk of local citizens "shopped" in it conl.ini.ioi.Lsly. cheeking out bags of grocer ies that, were given to every 100th visitor, Knfhusi.ism ran so high, in fact., that the Americans had i.o quit giving away the food parcels. At fair's end flic entire market was sold to businessmen who set it up in Belgrade. While the .supermarket drew throngs in Zagreb, a 'Turkish mother ami her Iwo begrimed young sons joined the crowd watching a laundromat in action in the American pavilion at. tin* Izmir 'Prado Pair.

The watchers, most of them broiight up on pump-and-buckol. launder ing, gaped in fascination. The idea was getting across: in Turkey, too, many might, have these things sonic day. Ho went scene after scene Iasi year in Italy, Japan, Morocco, Prance, 8|lain, .Sweden, <1 recce. Austria mid Tunisia. There were variations i.o suit the particular |>eoplc wlio watched, ol course, but. (lie basic theme re mained the same: Show them how we live. American participation in world trade fairs is a joint effort of flu* (invert uncut. ;u k I hundreds of private busi nesses of all sizes. It's designed t.o counteract. the advances Husain and her satellites made by eoiivcntrnl ing on the fairs, almost unchallenged by the free world, during the immediate postwar yearn. The growing threat was recog nized in lllfi-l, and 1'resident Kisenbower drew on an emergency fund t.o set. up the Otliei- of I nternal ional Trade hairs in I he Hop:irfmenl of Uonnnorre.

There were 200,880 -owners of Du Pont stock at the end of 1057, up from 168,675 a year earlier. Moat of the increase is due to the new employe-stockholders created by Du Font's Thrift Plan.

Electroplating, Adler explains, gives a more uniform-copper thickness. Actually, he says, the variation is legs than one per cent. Equally important is the leeway the manufacturer lias in choosing the steel core--from annealed low carbon to hard-drawn high carbon steel. National-Standard's experience with copper dates back to 1906, when the company came into existence as a producer of stranded copper lightning conductor cable. Since then it has made many specialty copperplated wires. The present process .is an extension of this activity. Several years ago the company introduced a lightly coated copperplate*} steel wire for use as television an tenna lead-in wires, tinsel, jewelry chain and building tie wire. Then, with the nation's communications industry burgeoning, National-Standard concentrated on develop ing heavier coatings to meet such special needs as precise copper concentricity and wire strengths up to a quarter- million pounds per square inch......................................... ' The company started experimenting with an electro plating machine originally developed by Herbert Kenmare and Walter J. Manson in New Jersey, Later National- Standard called in Du Pont electroplating specialists, who spent weeks at the Niles plant tailoring Du Pout's copper plating solutions to fit Hie new machine.

More than a mile of wire is in the machine at one time. Once the plating is complete, the wire is drawn to standard aiias ranging from .040 inch to ,81(1 inch in diameter. Copper and steel are teamed up to complement each other's best properties. Alone, copper wire resists cor rosion and is a superior electrical conductor, but it isn't strong enough to support itself properly in many applica tions. Steel, on the other hand, is strong but has dis couraging rust resistance and electrical properties.

It plans to add more as demand grows for electroplated wire with 15 to 40 per cent of the electrical conductivity of solid copper wire. The Niles firm also lias licensed a St, Louis ground rod manufacturer, who is producing coat-. tags of 20 to 26 per cent conductivity on heavy steel wire. .

More than a dozen manufacturers-- among them Baker, Tomlinson, Shaw Manufacturing, Sherman-Berfcram and Wlddicomb-Mueller--are using "Dacron" mjtjriu* now* \j ox-itsim ditj w j u iit u ciuce sofas and chairs containing the man made fiber at the June furniture market. Current models employ the cushion ing material as a complete filler for book or seat cushions, or as a wrap-around for Marshall .springs (innersprmgs) or foam rubber cores. It also works well in styling such tilings as tufted backs and special trim effects. Pubic enthusiasm for "Dacron" fiberfill products previously on the mar ketTM--pillows, comforters, sleeping bags and insulated underwear--will be repeated in the case of furniture, Du. Pont Textile Fibers spokesmen predict. It's being eyed for many other cushioned products as well. The unusual resiliency of "Dacron" polyester fiber, scientists explain, is the work of hexagonal benzene ringe that give its long molecular chains a girder-like structure. These are stiffer than the single strand chains of most other fibers. Once heat-set in a particular shape, "Dacron" fiber resists change and strives to return to its original form when It's bent. Creases that remain sharp in wash-and-wear cloth ing are an example of this property. To best bring out this quality of "Dacron" for cushioning, Du Pont lab oratory men worked for months to find the right combination of size, crimp, fin ish and length of fiber. The result was "Dacron" fiberfill, which has some phys- Iv/-'*d-!l |Ji v Id o fhli -Idi,fb wrU1f1fiot* 11 Oill l lfllbuirs'iaco. Qrvif the parent fiber. Its prime quality in furniture is rim- ply this; It's comfortable to sit, lie or lean on. It firms up gradually when compressed, and distributes your weight evenly instead of concentrating it on "pressure points," It's much more resil ient than natural fibers, can take more punishment and weighs less per cushion because of its lofty bulk. Extra benefits for the housewife; "Dacron" fiberfill won't rot or mildew, isn't attacked by moths, can be washed, dries quickly and isn't harmed by clean ing solvents. It has no odor, is lint-free and noiiallergenic. Finally, its resiliency keeps cushions plump and neat. All of which is important to remem ber, of course, but the fundamental tost obviously is this; sit on it yourself. ISHINGS FRONT Nuir it's smart to he thill--for a carpet* that is. .

That's why it's simplest and safest to use products that control a whole range of pests. The new DuPont Garden Insecticide, for instance, is a liquid combination of methoxyehlor, a less toxic chemical relative of DDT, and malathion, an organic phosphate that fights most of the hard-fo-kill insects. You can apply it--and other materials as well--with the handy new Du Pont Garden Hose Sprayer, which has two interchangeable nozzles for fine or coarse spray, ' a special control valve and back siphanage protection. Convenient to use, especially in small gardens, are DuPont squeeze dusters--polyethylene containers that need only light finger pressure to spread dust uniformly, Bose Insecticide & Fungicide, Floral Dust, Tomato Dust, Vegetable Garden Dust and 6 per cent Chlordane Dust . come this way. Each of the first four is compounded from a number of chemicals for all-out attacks. Rose Insecticide & Fungicide, for instance, contains methoxyehlor, lindane,. ' "Fermate" ferhain fungicide, sulfur and a miticide. This shotgun approach to post control--protecting plants simultaneously against a number of assailants--is : considered the best method for the amateur gardener.

Driving the expressway between the two cities takes seven minutes; the old ferry required about 40, - The tunnel is notable for its engineering achievemonts as well. "For the first time in vehicular tunnel design, an underwater tube has been built with portals emerging on man-made islands in the middle of the watercourse," re- ports the engineering consultant, Parsons, Brinckerhoff, Hall & MacDonald. From these Mauds in Hampton Roads, bridges stretch to the northern and southern mainlands. Motorists travel about one and a half miles under the . Roads and two miles over it. Twenty-three prefabricated steel-and-concrete tub sections make up the tunnel. These have teen sunk in place in prepared trenches and securely anchored. The tunnel is the longest of this type in the world. Inslde, the tunnel also features design innovations. Its .ceiling is porcelain-enameled aluminum, marking the first such use of this lightweight building material. The ceiling consists of 14,200 panels designed by Atlas Tile & Marble Works, Inc,, New York, extruded by the Aluminum Division of Bridgeport Brass Co,, Bridgeport, ; Conn., and enameled by Halrick, Inc., of nearby Danbury.; Hairick is a pioneer enameler of aluminum, using porcelain enamels supplied by Da Pont. . - The panels--12 feet, 9 inches long and 1 foot wide-- - have a number of points in their favor. They are only one-. ' third the thickness of conventional tunnel ceilings. Instal- liition, a matter of suspending eacb.parefabrwated panel In place, was quick and easy. ' What's more, the ceiling will require little mainte- nance, -since the. ceramic finish is immune to saifc-air corrosion and is easily cleaned. The promise of low long- - term maintenance costa, incidentally, was what really soli the tunnel fathers on porcelain-enaimelai aluminum. Like . the speed-up in transportation that the tunnel itself risjw resents, this modern building material was an effective ' way of meeting a problem. -- ' ' ' ' 24 heavy chemicals and insecticides. Lime also m the base for ingredients in your baking powder, toothpaste and even some candies. It's valuable, too, in metallurgical and flux ing processes and as a water softener. Impurities limit most limes for many of these uses. That's why an Oregon chemical plant or a Pennsylvania steel mill will buy Mississippi lime, confident that its con tent of magnesia, sulfur, alumina, iron, fluorine, phos phorus and other impurities is minute. As the mine's corridors probe deeper into the forma tion, gleaming white pillars are left standing as supports. Jumbo-mounted drills bore into the atone at levels up to 20 feet, cutting four 15-foot-deep holes simultaneously in a matter of minutes. Above the machine's reach, hand held drills continue the job. BLASTING CHEW TAKES OVER . Blasters load the holes-with DuPont "Extra" A-I dynamite in 11| by 8-inch cartridges, detonating it with Du Pont MS Delay electric Hasting caps to control the ex plosion most effectively and prevent excessive shattering. Working from a 90-foot truck-mounted boom, two men scale the ceiling with long steel hooks after each blast to dislodge loose rock fragments. . Mountains of blasted limestone are stored throughout the mine, waiting to be loaded into trucks by electric shovels and hauled to the primary crusher at the bottom of the mine shaft. Skip hoists carry the .stone to the surface, where it's crushed further. Some is sold as agricultural lime and livestock feci rotary and shaft kilns. From there it emerges as quicklime an incredibly thirsty product. When water is added, a tre mendous amount of heat is released. This hydrated lime is so fine that the total surface area of the particles in onethird pound equals that of a football field.

Du Pont engineers designed the refinery's tetraethyl lead blending plant and advised on its construction and testing. They continue to offer the refiner help in operating and maintaining the Mending plant. Tetraethyl lead,' cars, has become the life blood of gasoline refining. Auto engines will soon Mt 11:1 compression ratios, calling for 100-plus octane ratings to prevent engine knock, explained Bob Mifflin. "You can boost gasoline's octane number beyond a point with extensive processing, but it's terrifi cally expensive. It's more economical to gain the same objective by adding tetraethyl lead." But tetraethyl lead is toxic, so the design and opera tion of a blending plant is an exacting business. To keep it safe, Du Pont specialists regularly inspect operating tech niques and all equipment. They also screen and train all "Du Pont has done a terrific job," Jesse Boyce vol unteered, "During construction, those boys wore right out there with their slide rules and wrenches.

This wifely lament has been taken to heart by the chemical specialty manufacturers who are incorporating Du Pont "Ludox" colloidal silica in their home cleaning at; dirt ordinarily will accumulate. Surfaces thus stay clean Take these two products, for .example--"duo-deilay" double action cleaner for rags and upholstery and a new rug shampoo being -marketed by the Fuller Brush Co. Diluted in water, both are brushed or sponged on the fabric to loosen dirt. Up to this point they work like other fabric cleaners.

A couple of issues back we told how Eastern Products Corp. of Baltimore was treating the painted slate of Its Venetian blinds with "Ludox" to slow the soiling process. ANTI HU I* ACTUS, TOO For years industrial floor wax formulations have in cluded the Du Pont colloidal silica to make them Blipretardant and thus safer to walk on. In this instance, hard particles of "Ludox" are pressed into larger wax particles, providing a snubbing action that reduces slipperiness. Now the same idea has been adopted by a maker of household floor waxes. The A. S. Harrison Co. of South Norwalk, Conn., recently introduced "Preen" self-polishing wax containing "Ludox". The new wax is outstanding for its durability, the manufacturer says. It should remain attractive and protect a kitchen floor for an average of three months, lie estimates. "It's primarily a true wax, not a resin or shellac," explains Allrich S. Harrison, president, " `Ludox' reduces surface slipperiness while maintaining the valuable proper ties of the wax film. It gives us a safe waxed surface with a slip resistance well above minimum requirements."
