THE INDIA RUBBER WORLD 



849 



The International Rubber Exhibition 



THE Fifth International Exhibition of Rubber, Other Tropical 

 Products and Allied Industries, was opened in London, June 

 3, by Sir Owen Phillips, G. C. M. G., M. P., in the presence 

 of a large and distinguished gathering representative of all parts of 

 the British Empire and many foreign countries. 



ELXHIBITION MARKED GREJ^T ADVANCES 

 The exhibition drew a large and interested attendance of spec- 

 tators each session. In addition to the display of standard crude 

 rubbers, manufactured products and rubber-making machinery, 

 chemicals and ingredients, the notable feature of the exhibition 

 was the marked advancement in processes and products since the 

 last exhibition, notably gas-cured and gas-filled rubber, the rapid 

 preparation of crude rubber from latex, and rubber flooring. 

 THE PEACHEY PROCESS 



Prominent among the new 

 developments was the gas 

 cold cure of the Peachey 

 Process Co., Limited, ex- 

 plained by Messrs. Peachey 

 and Herring-Shaw. Fabrics 

 and other rubber products 

 cured by this process elicited 

 much enthusiasm from the 

 visitors to the exhibit, which 

 was one of the popular at- 

 tractions of the show. 



EXPANDED RUBBER 



The display of expanded 

 rubber product made by 

 Onazote, Limited, was also 

 a center of great interest. 

 The material known as 

 "Onazote" is a remarkable 

 new development in rubber 

 foam expanded with nitro- 

 gen gas under a process 

 patented by C. L. Marshall. 

 The material is considered 

 to have great possibilities 

 in its applications, due to 



its structure and internal gas pressure. .-Kmong the more obvious 

 of these uses are floats for various purposes, padding and 

 cushions for seats, balls, tire-filling and floor-covering. In the 

 latter use a good thickness of the expanded rubber is provided 

 between two substantial skins, which take the abrasive wear. 

 RUBBER FLOOR COVERING FEATURED 



Throughout the exhibition and, in fact, throughout the trade 

 today, there is evidence of a great revival of interest in appli- 

 cations of rubber floor-covering. The North British Rubber Co., 

 Limited, are the pioneers of rubber flooring in roll form. Their 

 "Parafior" rubber flooring is a most attractive article and, wear- 

 ing quality considered, it compares favorably with linoleum in 

 price. The Peachey Process Co., Limited, showed fine samples 

 of rubber flooring in colors produced by their curing process. 



Rubber tiling, with slots and keys, on a new interlocking prin- 

 ciple, was shown by the United Dutch Rubber Works, Limited. 



CRUDE RUBBER PROCESS 



The Davidson process of mainifacturing crude rubber from 

 latex was demonstrated by working models of the complete 

 plant. Rolls of perfectly dry rublK>r were produced from the 

 latex in 25 minutes from start to finish of operations. 



A special preservative known as "Siroxidine" is employed to 

 preserve the fresh latex in fluid condition for an indefinite length 

 of time. Should a big demand develop for crude latex in Europe 

 or America, there would apparently be no diffculty in shipping 



it in tank steamers for further treatment by the special coagulant 

 and machinery comprised in the process. 



BRAZIL'S EXHIBIT 



Prominently displayed on the splendid stand occupied by the 

 Government of Brazil was the following notice : "Rubber pro- 

 duction being absolutely unprofitable at present prices. Para and 

 .Amazonas arc changing over to other production, as timber, 

 vegetable oils, tanning and coloring materials, besides nuts and 

 cocoa, which always formed an important item in the Amazon 

 exports." 



The Brazilian exhibit as a whole was one of the most attractive 

 in the exhibition. Particular admiration was evoked by the 

 collection of native Brazilian timbers. 



PROMINENT EXHIBITORS 



.'\mong the prominent 

 American exhibits was that 

 of the Hunter process of 

 conditioning rubber, which 

 employs the natural element 

 of humidity in combination 

 with the proper tempera- 

 ture in circulation, shown 

 by Francis Shaw & Co., 

 Limited, Manchester, Eng- 

 land. This company spe- 

 cializes in plantation and 

 rubber manufacturing ma- 

 chinery, and is the British 

 representative of the Hunter 

 Dry Kiln Co. As this sim- 

 jile and practical method of 

 improving the compound 

 attracted so much favorable 

 attention, its adoption in a 

 number of British plants 

 will probably follow. 



North British Rubber 

 Co., Limited, Castle Mills, 

 Edinburgh, made a most at- 

 tractive show of its general 

 line, including mechanical goods, footwear, clothing, sporting, air 

 and surgical products. Distinctive and popular features of this 

 exhibit were the "Paraflor" rubber carpeting and the "Clincher" 

 golf balls, both of which attracted a great deal of attention. It 

 was, beyond any question, one of the most comprehensive and 

 effective exploitations of the show. 



Pirelli & Co., Limited, the prominent Italian manufacturer 

 of electric cable, india rubber, gutta percha products and pneu- 

 matic and solid tires for motor cars, cycles, etc., made a most 

 effective show, which, by the way, also included mechanical 

 and surgical goods as well as clothing and sporting effects. 



The "Pirelli" solid twin tire on one band was the subject of 

 much interest. It is built up with an open V to prevent stones, 

 etc., from being caught up and embedded in the rubber. The 

 two tire sections are designed to take the camber of the road. 



An interesting exhibit was that of .Mfred Smith, Limited, 

 Clayton, Manchester, who exhibited its lines of substitutes and 

 accelerators. "Velosan," one of the company's prominent spe- 

 cialties, is in active request among rubber manufacturers every 

 where. Alfred Smith, Limited, was established in 1856. 



Typkc & King, Limited, had a very attractive stand in which 

 were exliibitcd the company's various lines of antimony sulphides, 

 substitutes, mineral rubber and a general line of compounding 

 mgrcdients used in rubber manufacture. The "T & K" trade- 

 mark is accepted as a quality standard among rubber manufac-
