9(JI{E70 UI GERMANS REVEALED
Government Chemists Successful ly Probe Into 500 Patents

Washington, April 5.-After exton- sve experimenting with approximate Iy 500 German owned or controlled dye patents, the proper combinations of the patents for the quantity pro- duction of the dyes have been deter mined, and the Federal Trade con- mission has granted applications of the F.. I. du Pont de Nemours and company, of Wilmington, Delaware, for licenses under these patents to manufacture the dyes which have been unobtainab1e since 1914. Eight applications made by the National Aniline and Chemical company. of Buffalo, New York, have been grant ed by the commission also.
 The licenses were not granted un- til careful research and investigation by the trading with the enemy divi- sion of the Federal Trade commits sion to determine the proper combin ations of patents necessary to make particular dyes or groups of dyes. Examination of the patents disclosed the fact that in many instances in sufficient descriptions were given to enable anyone to follow the correct formulas. In some cases where at tempts to combine the ingredients were made, explosions or failure from ether causes resulted. In other cases the formulas worked without hitch when tried in a laboratory; but were a failure when an effort was made to produce the dyes in commercial quantities.
 After the proper combinations of patents for the mercantile production of dyes were established further
 
 sary to discover which patented for mula or formulas it was necessary to l follow in order to introduce the dyes ! into fabrics. It was not until these l problems were solved satisfactorily ! that the licenses were approved. The licenses for American use of 1 the enemy patents in nearly all cases are for the entire life of the patent l instead of only for the duration of I the war.
 | Additional licenses to American ! firms to manufacture drugs under l enemy patents have been issued by ] the Federal Trade commission, too. ! Licenses have been issued to the An ! toine Chris company, of New York, l 10 manufacture "barbital," (veronaD to the Calco Chemical company to manufacture "pro-caine," (novo- l caine,) and to the Diarsenol Chemi- l cal company, of Buffalo, to manufac- l ture "arsphenamine," (salvarsan.) l Announcement has already been made of former licenses to manufac- ! ture these drugs under enemy owned 1 patents.
 The first licenses for the manufac- 1 ture under German patents of 'neo- 1 arsphenamine," (neo- -salvarsan,) have 1 been issued by the Federal Trade 1 commission to the Farbwerke Hoechst l company, of New York. the Taka-
 mine Laboratory company of New l York, the Diarsenol Chemical com l rany, of Buffalo, and the Dermato- 1 logical Research Laboratories of Philadelphia.
 In granting applications for li- 1 censes to manufacture "barbital," which is regarded as one of the best l and safest hypnotics and nerve calm 1 atives, it is provided that the old l name 'veronal' may be used on 1 packages In an explanatory sense. | This drug has practically supplanted ! cocaine as a local anaesthetic having ] the effectiveness but none of the dan- l gerouS habit forming qualities of l cocaine. Before the first license was | issued to make ''pro-caine" it had | sold in the United States as high as 1 $720 a pound, but now can be ob-
 tained at less than $1o0 a pound.
 As in other licenses under enemy owned or controlled patents, the con-
 cerns to benefit by the licenses will
 pay the Alien Property Custodian
 per cent of their gross receipts from
 the sales of the articles involved oI
 2 per cent of a valuation determined
 by the Federal Trade commission.
