THE INDIA RUBBER WORLD 



[October i, 1908. 



India Rubber World received additional lists of the same kind, 

 but at the time these notes were being compared it was impossible 

 to give anything like a complete list of the visiting manufacturers 

 actually in London for this purpose or who were certain to be in 

 attendance. The list up to date, however, includes the leading 

 firms both in Great Britain and on the Continent. The difficulty 

 of being more complete in this respect is enhanced by the fact 

 that in every case the names of the intended representatives of 

 each company had not been learned. Mr. F. E. Buckleton is 

 named in the catalogue as the Convenor of the conference. 



THE RTTBBEa CONFERENCE. 



An important feature of the Exhibition was the International 

 Rubber Conference, which was attended by scientific men from 

 all the countries represented by exhibits at Olympia. One of the 

 illustrations in this paper is a view of one of the earlier sessions 

 of this conference. A number of papers were arranged for in 

 advance, and others were not announced before they were read. 

 Besides, the discussions, also to be published later, were partici- 

 pated in by a number of other members. At the time of pre- 

 paring this report the gentlemen named below were scheduled to 

 read papers, or deliver lectures, but all had not given notice of

NOTES AND PERSONALS. 



The advance notices in the English newspapers contained gen- 

 erally notices similar to this from the Liverpool Daily Post and 

 Mercury of September 8: 



"During the Exhibition Mr. H. C, Pearson, Editor of The 

 India Rubber World, New York, will give lectures on the fol- 

 lowing subjects: — i. Stereopticon lecture on the manufacture of 

 rubber goods in the United States and Canada, with views of 

 the exteriors of typical factories in the various lines of manu- 

 facture, such as rubber foot-wear, druggists' sundries, insulated 

 wire, clothing, etc., to be followed by views of the interiors of 

 factories making the same line of goods, including automobile 



parts. He will also show washing, drying, calendering and vul- 

 canizing. 2. A talk on crude rubber production will cover specif- 

 ically the gathering, /. e., tapping, coagulation, handling and ship- 

 ping of crude rubber in the Amazon countries, and in Panama, 

 Costa Rica, Nicaragua, Mexico, Hawaii, Ceylon, and the Fed- 

 erated Malay States, with typical views of the countries them- 

 selves. 3. A talk on synthetic rubbers, also on substitutes and 

 their assistants." 



The India Rubber, Gutta Percha and Telegraph Works Co., 

 Limited, had a stand on the walls of which was shown the 

 Evolution of Rubber Tiling from 1889-1908. The final result was 

 very beautiful, their imitation granite eflfects being exceedingly 

 rich. The whole floor of their exhibit was covered with beautiful 

 tiling also, while on the counters was shown fine samples of 

 hard rubber in various forms, insulated wires, cables, etc. 



Merens Brothers, as a part of their exhibit, showed a length 

 of J4 garden hose 670 feet long, made by a new machine that 

 makes hose in any length and without the use of the braiding 

 machine; in other words, it imitates the regular J4 rubber garden 

 hose, cloth wrapped and steam cured. 



Typke & King, Limited, showed some wonderful substitutes in 

 snow white, crimson and yellow, also rubber soling in which 

 their colors were used, green, yellow, red and black. The yellow 

 in these soles was particularly good. They had also in large glass 

 jars samples of their full line of colors and compounding in- 

 gredients. In two huge jars of water was shown their "Parateka" 

 in amber color and in black. It is a floating substitute with a 

 specific gravity of 0.964. 



The postmaster general of the German empire sent two im- 

 portant officials to make special inquiries regarding rubber. The 

 French government was specially represented by M. Dybowski, 

 the general inspector of colonial agriculture. 



An excellent musical program was rendered by Herr Meny's 

 Bleu Viennese Band three times daily — for an hour, beginning at 

 noon; in the middle of the afternoon; and from 7 to 10 o'clock. 



MORE ABOUT "TABBYITE." 



■"PHE company exploiting "Tabbyite" [see The India Rubber 



i 



World, September i, 1908 — page 404] have supplied some 



further details. They say: "We do not claim it to be a substitute 

 for rubber in the general sense, but we do know from practical 

 tests of the material, covering a period of three years, that it is 

 well adapted for insulating purposes, hard rubber flooring, mat- 

 ting, and the like. It differs quite materially from elaterite in 

 that it is soluble in the usual solvents, and its base is ozokerite. 

 It contains probably about 8 per cent, ozokerite, and a number of 

 volatile and non volatile oils. It is quite easily manipulated, 

 which distinguishes it from elaterite, the latter being quite diffi- 

 cult to handle in a commercial way. It is also quite diflFerent 

 from gilsonite, the latter being an asphaltene bitumen, and ex- 

 ceedingly brittle." The people mining Tabbyite regard the Utah 

 deposit as the only one in existence, and add : "It seems to be a 

 mixture of asphalt and paraffine base oils subjected to some 

 action in the way of heat pressure that has given it its present 

 character." 



Valentine B. Lang, vice president and general manager of 

 The Hartford Rubber Works Co. (Hartford, Connecticut), died 

 of heart trouble on September 22, at his home in Hartford. He 

 was born in New York city in 1858. Mr. Lang was elected vice 

 president of the Hartford company at the annual election July 17, 

 1906, and the additional title was conferred on him March 8, 1907. 

 He had previously, for some time, been connected with Morgan 

 & Wright, and was in charge of the construction of their large 

 rubber works at Detroit, Michigan. Mr. Lang was a thirty- 

 second degree Mason. He left a widow.
