A REALLY NEW TYPE OF GARDEN HOSE Artists sometimes exaggerate, but ours happens to be playing it pretty straight. This new type of rubber garden hose is light enough for a four-year-old to handle . . . and it does stay flexible. Even on those chilly spring and fall days it doesn't stiffen and become hard to handle. You can forget about reeling up this hose after every watering, too. It's built for outdoor living. . . takes sun light and weathering without a crack. There's no dan ger from loo much pressure, either. Shut off the hose at the nozzle and answer that phone--this hose won't swell or burst. A rugged neoprene cover protects the strong rayoncord reinforcement . . . gives this hose a long outdoor life. Remember the name neoprene when you buy garden hose. You'll see and feel the difference when you use it. N EORREN The rubber made by Du Pont since 1932 REG, U.

It's the latest bane of bank robbers, whose activities may be crippled by ... By PAUL GIGUERE A Boston bank is trying out a new kind of bandit trap that shoots film instead of bullets. It's an automatic movie camera that operates silently and invisibly from behind a one-way mirror, never blinks and has absolutely no nerves. It can capture on film everything that happens during a holdup. Little the bandit can do will interfere with the mechanical eye. The one-way mirror, only slightly larger than a peep hole, is bullet proof. Disguise wouldn't do much good, either. The bandit could wear a diver's helmet, but FBI experts studying the film later quite probably could get telltale-clues by the way he walks and moves his arms, by his general appearance and his clothing. For good measure, the film would show just where he stepped, so that detectives possibly could pick up heel marks on the floor. A heel impression has proved as helpful as .a fingerprint in the solu tion of several famous crimes. Within a short time, the bandit's performance also could be-released to television as a real-life drama that someone in the audience might solve. Once the hoodlum is captured, the movie record will continue as a relentless foe. He'll need a persuasive lawyer to talk away the recorded evidence. More than this, however, the criminal might be tripped up by the camera patrol before ho even stages the holdup. Films taken daily would be checked routinely by law enforcement officers; and since most robberies have to be cased in advance, known thugs entering the bank could be spotted and placed under surveillance. Masks, of course, cannot be worn, during casing. Suspicions behavior by anyone entering the bank during business hours might also become apparent in routine examination of what the camera saw. Evidence of odd actions could serve to alert the bank. FBI LIKES CAMERA TECHNIQUE The development of the camera technique comes at an ex cellent time, because banks all over tha country, particularly at new suburban branches, have been plagued by the worst rash of robberies on record. - Special FBI bank robbery conferences have been held with local law enforcement agencies throughout the nation. The effectiveness of the automatic camera patrol was extolled at a recent forum of Massachusetts police chiefs by Edward J. Powers, special agent in charge of the Boston office of the Federal 4 Chief H, J. Pelletier and Sj?t, T. II. Kane of ColuiMsel. Mu m force show liow police screen film from hidden earner Bureau of Investigation. Both the FBI and the Massachusetts Bankers Association have encour aged study of the camera method. - Behind the introduction of this new idea, however, is something more than a camera and special techniques. It became a practical possi bility with the perfection and production of re markable light-sensitive motion picturefilmssuch as Du Pont High Speed Rapid Reversal Pan, Type 931A. The high speed of this film makes it possible to take good movies under the subdued lighting conditions usually found in banks. Experts of Smith's Photographic Store in Boston, who have worked closely with federal and state agencies on the use of special cameras for bank protection, report that they have had good experience with the super-sensitivity and stability'of such films. Illumination from"a'lamp' post or ordinary light, bull: sufliccs to capture del ail tin I he lihn, t.iie a to re nay.-!- Moat of i he cameras l nod lor bank jn-oLection have not been operated eoni.intHuislv al Lull motion picture .speed, allhough this is possihte ivit.li a sufficientl.v large magazine.

If can he shil'led inslaniiv into fulbniolkm action by I figgcritig an alarm electronically or manually. Little motion is lost iti the three-second frames, and 200 feet of film is enough for an average day of batik business. Total film ivwl is only a lew dollars a day. and it's l.ltoughl t his cost might event ttallv be written off by reduced robbery in.suranee premiums. In one type of camera, a. fixed-focus, wide-angle lens sweeps a bank mitre than 100 feet long and almost as wide. Once enough hanks install the hint sent inels. and their existence becomes known, stick-up men will operate under a heavy psychological handicap.

Ill AMI >1 IN TIUNKrfMU'VriON' In the field of commercial transponai inn. all three of titanium's strong points,' corrosion resistance, strength and light weight, are of importance. The new General Motors experimental gas turbine car, the Firebird II, sports an ail-titanium body. Engine parts such as mufflers, rocker arms, head bolts and push rods are under considera tion for automotive use. : In marine service, valve trim, piping and sen water condensers have been tested and promise to outperform all coiners. Hardware and fittings have been evaluated on Star Class racing sailboats and are now being specified by some enthusiasts. Marine tests indicate that It would take 1,000 years to corrode titanium .001 inch. The use of titanium in commercial aviation has been accelerated by the tremendous development in military aircraft. Application of it in the engine nacelles of the Douglas DC-7 transport has resulted in a saving of 200 pounds per plane. As the jet age reaches commercial avia tion, titanium will play an important role in whisking pas sengers from breakfast In New York to lunch'in Los Angeles. ALSO AS ALLOYING AGENT One of the most unusual applications of high-purity titanium is as an addition agent in the manufacture of certain stainless steels, super-alloys and cast irons. The high purity addition has resulted in quality improvement of product, shortened melt cycles, more uniform efficiency and greater economy in the production of-these alloys. A major expense item in anodizing aluminum articles. Kindi as ire frays, grids and tumblers, has been replacing the racks from which the parts were, -suspended during the anodizing process. Titanium racks nave been found to re sist. (.lie cleaning, etching, brghteniiig ami anodizing solu tions used, Although these racks .in* more expensive than those c-f conventional materials, the increased lift-, esli- mated at more (ban I00 to I, justifies then- use.

Most of that day the truck climbed up mountains and wheeled down again, and arrived In Denver on sched ule a little more than a day and a half oat of Los Angeles. What's unusual about that? Nothing. Trucks of Pacific Intermountain Express do It every day. Their service is reliable and fast, and tires containing Du Pont nylon cord help make it that way. Problems caused by road failure of tires have been greatly reduced since P.I.E. decided to use only nylon cord tires. P.I.E. tracks operate under extreme conditions. Fur-' nacelle desert beat, heavy loads, constant speeds and high mountains put a strain on tires that used to limit their life to something in the order of 180,000 miles, oven with - retreading. By that time they either weren't sound enough to retread again, or had failed on the road.

The total life of such a tire may average up to 200,000 miles or so. One of the major reasons for switching to nylons. J'.l.E. officials say. is been use they can absorb abnormal punishment.

Hi-- The sign-off of a Du Pont "Cavalcade Theater" television show is often the sign-on of a new life for the filmed program. Chances are that someone in the viewing audience will see a use for the film to inform or entertain others, and will ask to borrow a motion picture print from Du Pont. Take "Disaster Patrol," for instance, the "Cavalcade" story of a typical Civil Air Patrol Squadron. C.A.P. officials say they detected an increase in recruiting activity soon after the story appeared on television. Now several squadrons are using prints of the film in their recruiting and public relations programs. "Ordeal in Burma" is another example. This inspiring story about American missionaries in Burma has been used by more than 300 churches throughout the country to stress the importance of missionary work and the need for its support. The telecast of "Man on the Beat" brought requests for the "Cavalcade" film from many police departments and police schools. The head of one school called it "one of the best films from a police public relations standpoint I have ever Been.' ' Prints of "Cavalcade's" salute to the American farm family, "How to Raise a Boy," have been used extensively by state 4-11 Clubs and Future Farmers of America groups since the telecast a year ago. Agricultural leaders have praised the program as a service to farm groups. 90 FILMS AVAILABLE FOR LOAN Since "Cavalcade" started on television in 1953, there have been more than 27,000 Individual, off-the-air showings of the SO films available for loan. More than 1.5 million persons have seen them. Civic groups, schools and business associations are among the most frequent borrowers. Probably no "Cavalcade" film has generated as many requests as "One Day at a Time," the true story of the founding of Alcoholics Anonymous. The film is In such demand by A.A. groups, hospitals and clinics that all of the available prints are booked for months ahead. The following reaction is .typical of letters that have been received; "Your sponsorship of this program has made it possible for millions of people to receive a message of hope for recovery which otherwise might never have reached them." Almost every "Cavalcade" film brings its share of requests. Someone, somewhere, sees a way of using-it to help him in his work or to help his community. To borrow "Cavalcade" 16mm sound films for showing to clubs or organizations, write to "Cavalcade" Films, Du Pont Advertising Dept., Wilmington, Del., for a catalog. There is no rental charge for the films; the borrower is asked only to pay return postage. Du Pont is glad that its films can work overtime to help bring interesting information to more people.

During this postwar period, production capacity was greatly enlarged by a $1,200 million modernization and expansion program. Fourteen new plants, besides the four now being built, are included in this growth. The Company's enlarged productive capacity enabled it to meet increased demand for Du Pont products. During this period, sales rose 194 per cent, from $849 million in 1946 to $1,909 million in 1955, or an annual growth rate of 18 per cent. Physical volume of 1955-sales was 121 per cent greater than for 1946. D: -: \ : 3 '' h t : : b*. >. :: . ;: -J - J > <} ! N i,! : ! i i ! f: i.f 5: : 8 Jin'S i i F: .

"Our representatives don't usu ally have such dramatic duties, but the work is never dull and benefits both the petroleum industry and the consumer." Davo Riekard himself is typical of Petroleum Chemicals representatives. He joined the division after finishing his war-interrupted education at Rensselaer Polytech (B. Ch,E,, '40). His Du Pont training gave Mm a wide variety of practical, experi- ence. In 1950, for instance, Davo was assigned as marketing and safety service representative in Den ver. His territory included five neighboring states and Alberta and Saskatchewan in Canada. Refineries throughout this vast area depended on Mm for tech- nieal information, safety consultation, marketing services and news of Du Pont petroleum chemicals. In 1952 Dave wag made a technical assistant in the Oiwatlims Section In Wilmington, Del. Here he worked on design, construction and safety problems involved in adding tetraethyl lead to gasoline in pro- elsely controlled quantities. Other assignments followed, and his duties today include liaison between the Petroleum Chemicals Division and two major oil com pa nits, and the coordination of services to these accounts at all their locations throughout the country.

Americans now eat about 70 million pounds of this fungi a year. Ten years ago they ate only about half that many. There is a twofold reason for the tremendous growth in the mushroom business--better distribution and better growing methods. An increased demand for mushrooms is of little value unless the fungi can be produced and distributed in large enough quantities to satisfy consumers. Mushrooms are not by any means easy to grow. For one thing, much tedious hand labor is involved in preparing and seeding the compost beds in which they are raised. Furthermore, thin work must be done in the dark. The crop also is plagued by a number of insects and diseases. For many years growers tried unsuccessfully to get rid of the large (sdarid) and small (phorid) mushroom flies. The larvae of these insects hatch in the warm, moist com post of the growing beds and quickly eat the young mush rooms. Entire crops have been lost in this way. Formerly, control measures consisted of dusting the mushroom houses with pyrethrum dusts to kill the adult flies. This had to Ik done two or three times a week, NOW FEWER DUSTINGS Now many growers use Du Pont "Marlate" 50 methoxychlor insecticide in a ton per cent dust and are able to reduce the number of dustings to one or two a month because of its good residual properties, '' Another Du Pont product improving yield and quality of cultivated mushrooms is formaldehyde. It is used to disinfect mushroom houses, equipment and compost beds to control "bubbles" and other fungus diseases that can quickly run through a mushroom house. Keeping growing mushrooms the right temperature is as important as pampering tropical fish. An increasing number of mushroom houses are being refrigerated to get the 45 to 60F. temperature considered optimum for grow ing firm, top-quality mushrooms.
