 as tst' Talk on fyrann.
 The large number and the great va riety of Pyralin articles being made to- day causes it to be almost impossible to do justice to the subject in the few mia utes' allotted to me. Bacause of this fact and also. because any slight knowl- edge I might be able to give in such a short talk would be of little interest un- less you understand something Of the na- ture of Pyrahu itself, have deemed 1t advisable. to devote the major portion of my talk to the, manufacture of Pyrslin, and then if time permits to enumerate the various ways in which 1t is used. e Although others have claimed the orig inal invention it Is generally conceded now that the first practical material of this nature was discovered by John Hy- al. of rolier bearing fame, about the year 1880. Since that date various changes have been made in tne ingredi- ents used and the methods. of manufac- ture, resulting in numerous patents be- ing issued and several companies being formed with different trade names for their product.

 The name Py-aiin is owned blythe Du Pont Co., and Is vsed exclusively by that company to designate its product in this particular field of manufacture. Similar material is being made today by other companies in this country whose products are Known to the trade by va rious names. such as sCenuioid, Fiber Ibid. Yiscolbid and Parisian Ivory Like material Is also being produced in Eng land, France, Germany and Japan, but nearly All of this latter production IS used in their own countries sin the man ufaeture Of artica4s. many of which arc exported to the United States
 The manufacture of Pyralin was be- gun by the Arlington Go. of Arlington, N. J., about 1890, and continued by this company uEt!l the year 1915 when ii was purchased by the Du Font Co.,. Be ginning with a production of a few pounds a week in two or three small buildings the plant at Arlington has grown until it now comprises over 100 buildings covers 50 acres Of land, and has a. capacity of over 100000, pounds Of Pyralin and one and one-Aalf mil lion articles per month
 The basic ingredient used in the man ufacture of Pyralin is . pure white tIs. sue paper made from the best grade of white rags. All the paper now being used at Arlington ts made at the Nor wich plant located in Greenev.lie. The local plant manufactures no other pa2el except this tissue and when running ful time can produce from five to six ton day.
 The only raw material excepting wa. ter which is used in the making of onl paper is the above mentioned whit, rags These rags are received in bale averaging about 800 pounds in weight The rags are first sorted by hand am all discoiored rags and foreign nnattel thrown out. After sorting, the rags which are in various sizes. are TUT through two cutting machines which ren der them uniform in size. They art | then ready for the beating or pulpins machines of which we have ten
 | Tn these heaters the rags are i'm nersed in water and are forced undei heavy steel roll containing bars; thi l roll grinds and beats the wet rags unt. the. stock is reduced to .ine white pulp The time taken for this operation varic according to the size of the heater ant 1 the quantity of stock, but. the averag is about ten to twelve hours per beate 1 load The pulp next passes through Jordan engine which further rehnes it removing Jumps. etc. and 1t is theI l ready for the Fourdrin.er paper ma chine
