THE INDIA RUBBER WORLD 



[February 1, 1913. 



NEW TRADE PUBLICATIONS. 



THE printing department of the B. F. Goodrich Co., produces 

 exceedingly effective work. Another illustration of this fact 

 is to be found in a lot of a dozen folders recently sent out from 

 that department, descriptive of various products of the Good- 

 rich mill. One large folder entitled "Comfort and a Few 

 Facts," describes the hot water bottles made by the company's 

 drug supply department. About thirty varieties of bottles are 

 illustrated in the folder. Anotlier folder, with eight detached 

 Icallets included in it, has to do with the automobile and its 

 appurtenances. The detached leaflets are each devoted to some 

 particular tire trouble, which is described with a cut of a tire 

 showing the effect of this particular trouble, after which the 

 remedy is given. These leafl_ets are entitled : "Skidding," 

 "Anti-Skid Devices," "Over-Speeding," "Wheel Out of Align- 

 ment," "Bad Roads," "Running in Car Tracks," and "Over- 

 Loading." 



The Goodrich Company, in addition, has recently distributed 

 three little folding Icallets calling attention to three of its lines 

 of production, namely, surgeons' rubber aprons, dental dam, and 

 infant bulb syringes. The circulars are each printed in two 

 colors and adequately illustrate the articles described. Regard- 

 ing surgeons' aprons, the company calls attention to the fact that 

 aseptic reliability and facility of sterilization can only be suc- 

 cessfully realized by the use of high grade material. The com- 

 pany's dental dam is prepared from fine pure gum and will re- 

 tain its elasticity under all conditions. Furthermore, it is trans- 

 lucent and does not get sticky. These three folders will be of 

 interest to dealers in these various lines. 



Three other folders pertain to the hose department, one 

 describing and illustrating steatn hose, another the Goodrich 

 Sand Blast Hose, and the third, hose used in drilling. It is an 

 effective lot of commercial literature. 



With the object of making their "Analyzed Chemicals" more 

 generally known, and at the same time keeping in touch with 

 their old friends, the J. T. Baker Chemical Co., of Phillipsburg. 

 New Jersey, issue a monthly booklet entitled the "Chemist 

 Analyst"; containing papers by practical experts on subjects con- 

 nected with laboratory practice. 



In the latest number received, "Electric Combustion Furnaces," 

 "Air in the Electrolytic Determination of Copper," and other 

 subjects are treated, while Mr. J. T. Baker, the president, gives 

 his views on "Manufacturing Incompatibilities." As appealing to 

 the chemist and analyst, the title is fully justified by the contents. 



The sprightly little publication issued by the Beacon Falls 

 Rubber Shoe Co., Beacon Falls, Connecticut, contains in its 

 January issue the usual amount of entertaining and instructive 

 reading. It is a 16mo., consisting of 16 pages and cover and full 

 of moralizing and humor, with facts interspersed with fables. 

 Incidentally, it leaves the impression on the mind of the careful 

 reader that Beacon Falls footwear is eminently desirable. It 

 has one excellent feature that publications of this sort sometimes 

 lack — there is just enough of it. Enclosed in this little booklet 

 is a new price list for 1913. 



The Katzenbach & Bullock Co., of 100 William street. New 

 York, importers and dealers in chemicals, have just issued a 

 24-page catalogue 3;/. x dyi inches, giving a list of the chemicals 

 in which they deal. These chemicals are first given in alpha- 

 betical order, and then the various trades supplied by the firm 

 are alphabetically arranged, while under each trade is a further 

 classified list of the chemicals that are of particular interest to 

 that trade. This makes the book exceedingly easy for purposes 

 of reference. 



The Eureka Fire Hose Manufacturing Co.. manufacturers of 

 the Eureka "Paragon Red Cross" brand of fire hose, have issued 

 a large wall calendar, on which there are a number of photo- 

 graphic illustrations showing the fireman at his hazardous occu- 

 pation. 



SOUVENIR OF CANADIAN TOUR OF BRITISH MANUFACTURERS. 



In connection with the British manufacturers' Canadian tour 

 of last year, under the auspices of the Dominion Government, the 

 "Financial News" of London has issued a handsome souvenir 

 number of 72 pages, richly illustrated. It closely follows the 

 itinerary of the party; one of its special features being the 

 reproduction of the groups photographed at various points. 

 Views of picturesque Canadian scenery and of street scenes at 

 the different cities visited, enhance the attractiveness of this 

 artistic issue ; while the narrative text is concise and full of 

 information. 



RUBBER 

 LITERATURE, 



TWO RECENT BOOKS WHICH REFER TO RUBBER. 



As Viewed by Our English Correspondent. 



In the present paragraph I am not referring to any new book 

 on rubber, but to the chapters on rubber in a new book. This 

 book is entitled "Industrial and Manufacturing Chemistry" (Or- 

 ganic), by Geoffrey Martin, assisted by 

 numerous specialists familiar with Brit- 

 ish and American practice. Section IX, 

 Part I, dealing with the rubber industry, is by A. J. Carrier, B. Sc, 

 of whose nationality I must confess my ignorance. As the 

 space given to the subject only covers twelve pages, and a good 

 part of this is occupied by illustrations of David Bridge & Co.'s 

 machinery, it will be seen that condensation has had to be severely 

 employed. 



It is doubtful whether the rubber industry of today can be 

 satisfactorily dealt with in so short a space, and a few paragraphs 

 on the general topic of the manufacture of rubber goods can 

 convey but little of utility to seekers of information. We read 

 that inner air tubes for cycles and motors are made of high- 

 class rubber; while cruder rubber articles such as dolls, toys, 

 goloshes, etc., contain a very large amount of mineral fillers or 

 rubber substitutes. 1 don't knowr that a high-class golosh is 

 really a cruder article than an inner tube, and I have my doubts 

 about the large amount of substitute present. Raw caoutchouc 

 is said to melt under ordinary pressures at about 190 degs. F. 

 to a gummy mass (presumably Centigrade is intended). In the 

 paragraph dealing with Devulcanization and Re-manufacture of 

 Rubber it is stated that it has not been found possible up to the 

 present to free vulcanized rubber from its sulphur, and thus 

 transform it into a product akin to raw rubber. This, of course, 

 is quite correct, but why head the paragraph "Devulcanization"? 

 This part concludes with some useful trade statistics. Part II 

 is by Mr. Martin himself and deals efficiently with the topic of 

 synthetic rubber, and is probably the most up-to-date detailed 

 account of the chemistry of this somewhat abstruse and com- 

 plicated busmess. 



Another new and imposing volume, in which rubber finds 

 mention, is "Industrial Chemistry," edited by .\llen Rogers and 

 .■\Ifred B .\uhert and various collaborators. This is an entire'y 

 American production. The information on rubber and its manu- 

 facture covers only 2]/2 pages in the chapter on resins and gums. 

 The general statement that raw rubber is very impure, with 

 water, sand, wood, etc., will doubtless be objected to by planters 

 in the Far East. It is hardly correct to say that litharge is only 

 added as a filkr in inferior grades of goods. Lender "Reclaimed 

 Rubber" we read that the most widely employed method is Good- 

 year's, which consists in reducing the waste to a finely divided 

 state, mixing with normal rubber and sulphur and beating for 

 several hours under heavy pressure. 



.■\nother statement is that hydrofluoric acid is kept in hard rub- 

 ber containers. In England, at any rate, it is kept in gutta-percha 

 containers. Altogether, the rubber information strikes me as 

 decidedly weak, compared with the treatment of other materials 

 and manufactures in the volume.
