"As you know, Doctor, I esteem the 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. "Surely you see that these bristles have finely tapered tips. This accounts for the ease with which paint is released. And these split ends help to increase paint-holding capacity. Both are significant clues to brush quality. "As for wear, I shan't bore you with a dissertation on nylon's durability. Suffice it to say that `Tynex' bristles wear three to five times longer than the ordinary kind. They are also easier to clean. "To sum up, Doctor, a uniform, man-made bristle, plus the skill of brush making artisans are what make this brush so superior. It's really that simple." BETTER THINGS FOR BETTER LIVING ...

Some .mUioril.ics have flefined weeds as planks growing where they are not. wanted. Others, more charitably,, have calk'd them plants whose virtues are still undiscovered. Whatever words are used, the fact remains that weeds are (.lie thistles in tmflire's (lower bed. the "bad guys" ol` the plant, world. For one thine, these botanical bandits hold up American agriculture for an estimated three to live billion dollars every year. They roh crops of food and water; rugWised, for example, requires three times as mueli water as corn, 'I'he billion and a half dollars runners spend on lighting weeds amounts lo more than seven per cent, of the value of I heir crops. Weeds also nick commerce and industry for a sizable sum. Figures arc scarce on non farm weed control costs, huf. a large railroad, for example, may spend a half million dollars or more a year keeping its right-of-way clear of vegetation. The traditional method of coni rolling weeds lias been by direct physical assault, usually hoeing or mowing. But labor costs an* high, and the weeds begin growing again as soon as the hour or mower is out of sight. Mori; and more, the men concerned with destroying weeds are turning to chemicals, just as fanners have enlisted chemicals i.o protect crops against bisects and disease. (Ilicmical weed omi.ro) is usually cheaper in the long rim, and its effects are generally loaifer-lasl int;.

Additional units were: placed in production during the year, as well as research and de velopment laboratories for the support of operations. 'Hit: major portion of i.he eolist.ruction project, esti mated t.o cost, well over a billion dollars and repuled to be the largest ever undertaken, has been completed. How ever, it is likely that some construction forces will bo at work on (.lie site for an indefinite period. The Company continued to operate the Indiana Ord nance Works at Charlestown, Ind., to meet Army produc tion schedules. This plant was built and operated by the Company for (.lit: Government in World War II. Its principal product is military smokeless powder. Capacity production from expanded furi lilies to pro duce titanium metal is expected early in 1955. Thin expan sion was started in 1952 at the request, of the Government. 'The Company over the years has sponsored various programs to support scientific education in colleges and universities. Appropriations for this purpose have been increased from lime to time arid total $805,000 for the academic year 1955-50. Recognizing the growing need to encourage science and engineering in colleges and universities. Hie Company lias expanded its (iaatieial support for such work. It has also extended it to help support, improvement of teaching, now the largest single phase of the program. Studies indicated a neetI to help advance the teaching of science and maihematics in high schools. Since it is in secondary schools that students begin to decide on (.heir careers, inspiring teachers at (Ids level can encourage students who have n talent for science and engineering. 'Hie program, authorized in !95'!. provides-: for grants totaling .375,00(i. .11, wilt go t.o I l colleges aiwi universities for f raining high school teachers in these fields for flit! 1955-50 academic year. Because progress in college and university science teaching also needs encouragement, f.wo plans have been developed. Under one, grants for at postgraduate teaching assists ntships were made to as many university chemistry departments. In the <4 her plan, grants were mace to 59 privately supported liberal arts colleges and smaller tech nical schools l.o advance I he- teaching of clieiuLsf rv. Industrial support, of postgraduate science studies through fellowships was pioneered by I)n 1'onf in .1918. .Since then, more mid more such fellowships have been granted by industry and others. Couscqurnl ly Du Pont now is placing relatively greater emphasis im .support, of leaching. For the 195a-5(i academic year the Company is providing 57 pn.si graduate fellowships for 8K iast it utioiis. In 1949 the program was broadened when a total of $1.90,1)00 in grants was made Cor unrestricted fundamental research in chemistry in fen universiues. The amount, has now been increased to $279,000 fur 8-1 institutions. Jn no pan. of its program for support of scientific education does the Company .stipulate specific research work t.o he undertaken, nor docs it. require any commit monk as to future employment. The benefit to Du Pouf lies in general progress in (.host: brandies of leaning on which the Company's opera lions art: bused. Advancement in leaching ami fundi.menial research in the sciences creates a reservoir of ability and new knowledge essential lo industrial research, in the broader view it; is also essen tial to national prosperity ar.d security. Last year conrt.ruct.ion began on three additional laboratory buildings at. (.lie Experimental Sf.nlion, near Wilmington. When ilicy are completed early in I9f>(>, oil ten manufacturing departments and (.he Chemical and Engineering depart incuts will have facilities for long-range research at the Experimental Station. In all. more than 1,009 technical people then will be engaged in research at the station. A like number of research personnel will continue to be located in labora tories at: plant sites. Since its establishment more than 50 years ago, the Experimental Station lias been concerned primarily with long-range research aimed at diversifying the Company's business. A formal program of fundamental research was started there in 1927 and 1ms become an important activity of each research division. A fruit fu! source of scientific knowledge, it, has provided the basis for the discovery of new products and processes. The discovery of a new class of synthetic, crystalline polvriers, for example, provided the foundat ion for development of nylon fibers and molding plastics as well as the more recently developed '`Dacron", "Mylar" and "Gronar".

As l.o flu* companies in Argentina and Brazil, this was reported to you last, year. .Joint ownership of Canadian Industries Ltd. (C-J-L) was terminated in July. Under the plan approved by its stockholders, C-J-L's business and assets were divided Ixiiween two new Canadian companies. C-I-L became a holding company, known as On Font, of Canada Securities Ltd., holding all of the stock of one of the new eompmiiei, Du Pool Company of Canada Ltd., to which was transferred C l Its nylon and cellophane business and assets and certain of its non-tnanufarl min;.;, assets.

The upholstery can take a breath of air through invisible pores built into the deeply grained pattern. And this new development is important not only to furniture manufacturers and up holsterers but to all who sit. Before Russel Wright designed the Castleton grain and IJu Pont made sure it could breathe, upholsterers had lo set; that air somehow escaped Irom plus! ic-covercd anas. They used a do! h back in;: on a cushion, for example, nr made us*! of vents nr grommets. Nall;ruby, a clot.hbackeii i ushiim isn't reversible. With "Ifobriliie" t hat breathes, nr, air is I rapped inside (.lie cushion. When you sit. down, the air in I he cushion is pushed mil through the tiny pores. Air cnin.imies i.o pass through the upholstery so that, it. remains i ool and dry. The person who relaxes im a l ast let on-covered seal of foam rubber enjovs the I'ul! comfort of the resilient, porous tilling. There is no (neaped air to build up pressure and create a hard seat.. The cushion, entirely covered with Castlcf.on. can be turned or reversed any time. Besides add nr. comfort for the occupants and making possible reversible cushions of vinyl plastic, die new Castleton retains all the easy eare qualities of l.radilinnnl "Fabrtlile", 'The upholstery wipes clean with a damp sponge. Less soil accumulai.es in the first, place because the material's dry, high-slip finish encourages the dirt to keep moving. Taking advantage of a knitted backing, Castleton is engineered chemically to stay pliable even tinder heavy service conditions. The new upholstery is available to furniture manu facturers and upholsterers in 15 colors, selected by Russel Wright, Furniture upholstered in Castleton may soon be purchased at most furniture dealers.

The modem mobile home most not only be convenient and attractive, but it must be prepared to lead a dual life of highway vehicle and stationary house. The exterior finish mast withstand the wear and tear of road traffic and the effects of southern sun, northern blizzards, or coastal salt air. For this reason, many manufacturers have taken a cue from the automotive industry and finish their mobile homes in durable Du Pont "Dulux" enamel. The Vagabond Coach Manufacturing Co. of New Hudson, Mich., one of the oldest in the business, lias used Du Pont finishes from the time ft started in the early '30s. Vagabond's 1955 models gleam in exterior combinations of sparkling "Dulux" colors--Bittersweet and Majestic White, Glacier Blue and white, and Spring Green and white. The birch interiors of Vagabond homes are finished with "Dulux" clear finish. "We are now painting all trailers," says George F. Miles, treasurer, "because color is important to most, people these days--in their houses, their automobiles one! their clothing. Mobile home customers are now more con scious of color on the outside than on the inside." Dealers agree with manufacturers on the selling power of color. This is especially I rut.'.

What does the trend mean for ear owners t Hero to answer our questions is Paul Richard, an automotive engineer mho is the eyes and ears of Du Pout's Petroleum Chemicals Division in the Motor City Q. What does a higher compression engine mean to the motorist? A. It means belter ear performance. It actually gives greater horsepower and better fuel economy. If you were to increase the engine's compression ratio in your present car, it would automatically produce more horsepower. If you were a conservative driver and never used this maxi mum horsepower, the higher compression engine would give you more miles to the gallon than you're getting now, Q. Yet today's cars seem to give no better mileage than the older ones. Why? A. They're heavier. The same amount of gasoline is hauling more weight around at higher speeds, Q. Which of the 1955 model U, S, cars has the highest compression ratio? A. This year both Buick and Cadillac have a compression ratio of 9 to 1. Five other ears have compression ratios of 8,5 to I, The lowest this year is approximately 7.3 to 1. This compares with a weighted average of compression ratios of 5 to 1 in 11)30, so you can see how engine com pression has climbed. Q. I've heard that a high compression engine operates at a higher temperature. Is this good or bad? A. A high compression engine does operate at a higher temperature (luring the combustion part of the cycle. During other parts of the cycle, however, it actually runs cooler. This is demonstrated by the fact that a smaller a low eompmssion engine of the worm horsepower. This point is 11 ml. you get more actual work on I, of the flic! in a high compression engine. I mss gasoline in wasted in beat to Lilt! cooling .system. Is il. good or bad? It's good. Any heal. engine- steam, gasolitm, dies-cl or what have you--is more efficient when il operates-; al, a higher eombusf ion temperature. (tL How high are cninprossion ratios likely to go? is there any practical limit on how high they can go, or will limy just go oil increasing indefinitely? A. in the industry, compression ratios as high as 12 to I are foreseen by i960. It's a little hard to say what the limit may he. One limiting factor is fuel. 'Hie higher the compression of an engine, in general, the higher the octane number of the fuel required for knock-free operation. At present there is a. practical ceiling on i.lie untune numbers of fuel that, call he produced economically in the vast quantities new led for automotive consumption. We can make 100 octane fuel, of cour.se, but it's difficult to make it in the quantities required al. o price the motorist warn Id be willing to pay. A 10 to 1 engine, for example, would require a fuel of about I 00 to I (in octane. I'm taking a little poetic license here, because our octant; scale ends al. 100. But engine requiromonfs arc going beyond that old 100 mark. O. 1 low is (lie petroleum industry facing up to this situation? A. By 1060 refining processor; now 1 icing developed are likely to be in operation. ! in proved antiknuek additives also are being worked on. Anolher facet, is that auto manufacturers may design I heir engines so that higher compression ratios cun be used without increasing octane requirements very much. The design of the combes! ion chamber, carburetor and spark advance can govern to some degree lliu octane requirements, in effect, you design the engine to burn its fuel-air mixture more rapidly. OCTANE l<ATONES U.IMIt LAST O. Flow high is the octane mini her of gasolines now cm the market? A. Gasoline rated at do octane is now generally avails hie at- premium pumps. In many locations it's possible to buy even higher octane fuel in the premium grade. These fuels meet flic requirements of present engines, and they are evidence of cooperation between the automotive and petroleum industries for the inof.nris.f's beneiit. The two exchange information through the American Petroleum Institute and the Society of Automotive Engineers, for example. In addit ion, represen fill ives of the oil companies and their additive suppliers are sin tinned in Detroit lo stay abreast, of developments. My job is to help keep Du Pont and our petroleum customers up to date on the fuel and lubrication requirements of new vehicles. This lets us know the direction our research al, Du Pont should be taking. We're following Detroit's work on automotive gas turbines, for example, with great interest, although no turbine-driven cur may tie on the road for ton years. We also keep the automotive people informed on new develop ment* in chemical addivil.os. This exchange of information is invaluable to all concerned. O, What is the petroleum industry promising for file next few years im far ;ih higher octane fuel is concerned? octane gasoline. It wuHoriginally osl 1 mated that wc wouldn't have; tills until I Olid, bill, the climb in octane numbers is being accelerated. The addition of more id methyl lead will be? partly responsible, but. most of the increase in the years ahead will come through improved relining. G. .Besides n higher antiknock requin men!., what prob lems are high compression engines presenting for ihe petroleum industry? A. .Engine deposits left in the combustion chamber by fuel and oil are a serious problem. They cun raise fhe octane requirement of an engine approximately eight, points, and cause knocking. Cleaner burning gasolines and lube oils that leave k?s:.; residue in tins combustion chamber are an approach io the problem. Du Pont.'.*-; petroleum laboratory and ol here, toy nil that n more volatile tube oil would cut down engine deposits, for example. This more volatile lubricant, designated as a multi-grade oil is ticing marketed now by many refiners ;is iheir fop grade oil. It can reduce deposits, thus lowering the engine's octane requirement si good f.l rn.su or four number;-;. III66KHT IfIMb I'KEILM'I'ION Engine deposIL-; arc also responsible for I he toughest problem presumed by high compression en gine;.; preignifion. Ah compression ratios climb, flic? deposits glow t;ntier certain operating conditions, igniting the fuel air mixture promaturely. This raises the oclarn; nsquirement, may cause power loss, and in severe eases e;e\ break pistoils and warp exhaust valves. iP . ;'!' r' '? ' ;;; ;i' .< . hi ' . .. ' '' .. O. Wli at. can you do fo lick thin? A. There arc two possible attacks. One is to reduce deposits. 'Hie* other is to modify I lie deposifs in some way so that they will be less harmful. Du Pont, along with the rest of those concerned, is pulling a lot of research effort on flic problem I predict if will tic licked. r^ . " | o. Mow ran I tell whether my car needs regular or premium gas? A. Cheek the owner's manual, which usually specifies the grade; required. If il, isn't specified, then Irv regular. If the car muchly knocks on regular, you nerd premium. Premium gasoline also warms up f he engine fasler. reducing the danger of crankcase dilution and lofting the engine make better use of the fuel it receive*. <>. Will you Hnmiiifirire wlmfc the motorist can expect in the way ol'over-all performance in his fttlure cars'? A. Future cam will have more power, giving still better performance than is available today. By performance 1 mean acceleration throughout flic entire speed range. .Because high compression engines arc more efiieient, this improves! performance will mil be achieved at the expense of fuel economy. Auto manufacturers anil refiners are working together lo make Ibis possible.  M ......._............ 41 Hh;;r a.in. t!n* ;>IIheld llii-ii till P*mi rlrot ihi' ('mnln>rlmnl RI I'vr NtCII.O.

Klerlroplaling consisted almost entirely of plat in ip gold nr silver for aesthetic elTcefs. 11 was not, until l In.! arrival of (.he automobile Hint, electroplating as wo know if. gained momentum. I'lari v decorative and oven functional parts. such ns head lamps and rritiiaf.or grilles, wore often made of brass. A bright, attractive luster on these parts required hours of fed ions hand rubbing. When a layer of nickel was deposited on the brass, lime and labor were saved, and elerlruplahing was on its way to breaming a major industry. < >ne of the country's earliest supply linns in flic elec troplating field was founded in 1885 by l.wo Herman im migrants named Knessjer and I lassladier.
