A ' / ' The new Kent cigarettes on" this' same group caused no drop in average skin temperatures'. In all the tests over a'period of six months about one third of the people were found to be' sensitive smokers and two thirds non-sensitive. .

' ,,.Research scientists of the Army and Navy'joined forces with i scientists working under grants from the National Defense Research Committee to develop a truly efficient filter for both gas masks and respirators. .The work culminated In the development of a v. ' revolutionary new filter material, which was subsequently adopted by the Metallurgical Laboratory of the University of Chicago/- then working on the nation's first atomic pile. :: . Today this new filter material removes radio-active ` contaminants .from the effluent gases discharged-into 'the air at : Atomic Energy Commission plants in various parts of the country.. It is also used in both gas masks and respirators. :Its adaptation for use as a cigarette filter which is--probably more widely the country. .

Previous filters, he pointed out, have been only relatively efficient. The new Kent filter, which is known as Mioronite because it removes nicotine and tar particles as small as two tenths of a micron (which is two ten thousandths of a millimeter) reaches a peak of efficiency heretofore unattainable in a cigarette filter. / Ih the development of the new filter, Dr. Parmele worked closely with Dr. Harold W. Knudsen, technical director of Hollingsworth and Vose, East Walpole, Mass., who was associated with the Naval Research Laboratory's work on the new filter material during the early days of World War II. v -. ,:i r. V-' ' St. . - ; ; 4 . I^ An affiliate of Hollingsworth and Vose Company, which did a great deal of war-time pioneer work and post-war development on filtering materials, is supplying the filter material for Kent cigarettes. , 0042036$ Months of intensive research and development work were carried out in Lorillard's research laboratory following the removal of this material from governmental security classification about two years ago, (more) .y- * - i * ; . At first the n e w filter material was so effective It 'removed all the smoke. The smoker puffed in only warm air. 'Various carrying'' agents'-for. tne! filter, were tried in an effort .to. reduce the., maximum,efficiency,of. the filter. Hundreds of :experimental cigarettes, were made and tested under controlled ;laboratory conditions. The ultimate goal'of this research and development work was to provide a filter which would remove maximum quantities of tobacco tars, which a r e 'irritants in cigarettes, and of nicotine; which' is highly toxic. At the .same time the smoke had to retain the fine flavor and aroma of the cigarette's tobaccos to fully satisfy the smoker's desire f o r smoking pleasure. The desired results were achieved by combining the new filter materialwith a carrier fiber in scientifically determined proportions. In addition, however, the cigarettes had to be easy drawing to meet the demands of smokers. Ultimately an ingenious method of interleaving the'filter material product with a cellulose substance was developed. This provided filter channels through which the smoke traveled. The filter action takes place as smoke moves through these channels. In explaining how the new filter works. Dr. Parmele pointed out that its action is dependent upon the phenomena related to physicai__chemistry. c c o N :.<7Cj) j i \ \ 6 - - r' "Basically,"it is quite simple", he'said. "The filter material, which; is a' secret'Jhineral*-ingredient, has certain - i ; -.*; : peculiar physical properties"when seen under the microscope. As the smoke ;is- drawn' through? the 'cigarette to the filter tip ' i. it travels through the chahhefs' provided by the interleaving of- the cellulose material. Here it must pass through the filter material. As it does so, both tobacco tars and nicotine become affixed to the filter material due to its unique surface activity, just as in the atomic plants this same filter material removes radio-active contaminants or in the gas masks and 'respirators it removes small particle dispersions of toxic smokes. "Until now filter cigarettes were either of cotton or paper or of combinations of cotton and paper, Because these materials do only a partial job of-removing tobacco tars and nicotines they-are relatively inefficient. Now, however, we have a cigarette filter which is so efficient that in tests it has even filtered out air-borne bacteria and other microorganisms. It thus permits smokers to Inhale air which contains fewer bacteria and dust particles than the air they normally breathe. Actually, we are doing on a small scale with tobacco smoke what the atomic energy plants are doing on a much larger scale with radio-active, contaminants.. In.both instances harmful materials are removed' by filtration. The basic scientific principles of this filtration are. the same in both instances and the differences are really those of degree,..". .

"We knew from virtually the very inception of our research that we could filter out everything, including the smoke," Mr. Ganger said. "But we realized that the smoker must get full flavor, taste and aroma if he is also to get smoking satisfaction .which is one of the basic reasons for his smoking in the first place.--.To get this balanced combination required hundreds of .hours of research and experimental work." P. Lorillard Company is the oldest tobacco company in the United States, dating back-to 1760 when Pierre Lorillard, a young French immigrant, opened a New York tobacco factory and store. For almost two centuries Lorillard has" been a pioneer in its industry. In 1 7 8 9 it published the earliest known American tobacco advertisement. It originated, the idea of putting up snuff in animal bladders which were dried and tanned like parchment and were the forerunner of cellophane, which this same firm years later was the first to use on packages of cigarettes to preserve freshness. It was also the first to use aluminum_foil and to use tear tape on cellophane wrappers. Th company*s products have 'served our armed forces in every- war the nation has foufcht. **. .. . . - .
