THE INDIA RUBBER WORLD 



[January 1, 1917. 



unaccelerated products showed the same breaking point, but the 

 elongation of the accelerated product was found to have been 

 reduced one half. 



MISCKr.r.ANF.OUS. 



AyilhraijuiiKiiic: Recommended in 3 to 5 per cent strength in 

 batches containing rubber substitute. In a typical mixture con- 

 taining rubber sul)stitute it reduces the duration of vulcanization 

 from 2 hours to one-half hour. 



Antipyrinc: Acts like anthraquinone. (Ditmar.) 



Naphlhylamiiic: Acts like anthraquinone. (Ditmar.) 



Urea: This and such derivatives as guanidine have been found 

 useful. (King.) 



FormanUidc: Many patents cover the anilides, such as for- 

 manilide, C„H, . NH.CH :0. 



Thioformanilidc: CoH,, . NH.CH :S. Cited l>y King. 



Albumen: The direct addition of proteins to rubber, as de- 

 scribed by W. Esch in German patent No. 273,482, November 

 22, 1912, presents an interesting possibility. The protein, usually 

 egg albumen, 15 parts, is mi.xed with 2 parts hydrated lime or 

 magnesium hydroxide to form a paste. Low grades of rubber, 

 when mixed with this paste, dried, sheeted and smoked to render 

 the albumen insoluble, are considerably improved thereby. 



GASOLENE FROM OIL SHALES, 



Probably the advancing cost of gasolene and other products 

 derived from petroleum will one day render profitable the 

 distillation of the vast deposits of so-called hydrocarbon shales 

 of the Green river formation of northwestern Colorado and 

 northeastern Utah. The United States Geological Survey has 

 been investigating these deposits for three years past, and the 

 director in his report states that very rough but cautious calcu- 



lations indicate that the distillation of shale from beds over 

 three feet thick in Colorado alone will yield more than 20 

 billion barrels of crude oil from which 2 billion barrels of 

 gasolene can be extracted. A detailed report of these investiga- 

 tions, with a statement of the possible gasolene production by 

 llic Kittman process, is now in press. 



HEAVY AMERICAN EXPORTS DUE CHIEFLY TO 

 THE WAR 



TPH.VT the European war has been principally responsible for 

 •'• our tremendously increased exports of the past year is 

 incoutrovertibly shown by the official Commerce Reports of the 

 United States. Our exports for the ten months ending October, 

 1916, amounted to $4,443,326,271, of which shipments to the 

 value of $3,541,446,875 went to the .Allies and their colonies, 

 whereas our entire exports to all other countries totaling 

 $901,879,396. only slightly exceeded one-fourth those to belliger- 

 ent countries. Considering only commodities suitable for mili- 

 tary and naval purposes our export trade for the ten months 

 ending October, 1916, amounted to $2,541,733,040 as compared 

 with $549,369,725 for the corresponding period of 1914, or nearly 

 a live-time advance. 



The following items are of particular interest to the rubber 

 trade :
