THE INDIA RUBBER WORLD 



[July 1, 1914. 



nal of the Society of Chemical Industry" of May 15. I refer 

 briefly to some of the points established: 



The viscosity of a rubber solution varies according to the 

 particular solvent used. Fine Hard Para after being washed 

 for 45 minutes on the rollers lost a good deal of its viscosity, 

 while Castilloa rubber suljjected to the same conditions also 

 lost viscosity, though not to the same extent. The author dis- 

 cusses the best method of graphically expressing the results 

 obtained in viscosity tests, and among other subjects touched 

 on is that of the effect of impurities in the solvent used, e. g., 

 xylene in benzene. Such impurities are shown to affect the 

 results, hence the necessity for employing pure solvents. A 

 scientific dissertation leads up to the remark that it is dififi- 

 ■cult to obtain absolutely concordant results for the initial 

 viscosities of solutions even of the same rubber and of the 

 same concentration, unless one works under absolutely uni- 

 form conditions. .All this and the absence of any claim on 

 the part of the author that viscosity determinations are yet 

 of technical importance indicate that in this matter we are 

 very much where we were four years ago. 



THE WEBER RUBBER CO., LIMITED. 



As some little confusion may exist as to the identity of this 

 firm, on account of the legal action reported in these notes 

 and elsewhere, it seems advisable to clear things up. The 

 Weber Rubber Co., Limited, is a firm formed a few months 

 ago to take over the business of the Weber Rubber Co. (the 

 plaintiffs in the action). The personnel and management are 

 quite distinct, and it seems rather a pity that the new firm 

 did not choose some other title. The Weber Rubber Co., 

 Limited, whose works are in Weber street, Collyhurst, Man- 

 chester, makes a specialty of rubber heels, and the manager 

 is Mr. Robert Flinn. 



In this correspondence for May the position of Mr. E. S. 

 Gray at the works of the Rubber Regenerating Co., TrafTord 

 Park, Manchester, was incorrectly given as under-manager 

 whereas it should have been assistant in a particular capacity.

make the formal opening attracted a very large number of 

 people, and it was found impossible to seat them all in the 

 main hall. Many more were accommodated in the galleries, 

 and yet it was impracticable to find room for all those who ap- 

 plied for tickets and desired to attend. .After the opening

 all the leading rubber people of London and many from all

Fifty-four different governments are taking part in this
