NEW TRADE PUBLICATIONS 



THE Peachy Process Co., Limited, 40 Gerard Street, London, 

 W. 1, has recently issued a pamphlet covering matters re- 

 lating to the capitalization of the company; the chief advantages 

 of the Peachcy process of cold vulcanization; a short biography 

 of the inventor ; and separate reports by Dr. Henry P. Stevens 

 and Frederick Kaye on the technical value of the process and 

 validity of the patents. These are followed by a brief historical 

 review of Goodyear's hot vulcanization process and a state- 

 ment of its drawbacks. 



The E.\ci-e-Picher Lead Company has issued a 16-page 

 booklet listing the lead products which it manufactures, many 

 of them being used largely in the rubber industry. The book- 

 let is illustrated with half-tone illustrations of the various Eagle- 

 Picher plant.i, and includes a graph showing the derivatives of 

 lead. 



.\t the Chemical Exposition recently held pj New York 

 City, the Buffalo Foundry & Machine Co.. Buffalo, New York, 

 distributed a booklet covering some recent developments in vacuum 

 dryers, evaporators, vacuum pans, chemical equipment, etc. 

 Many manufacturers of rubber goods are well acquainted with 

 the "Buflovak" line of equipment and will be interested in its 

 newer developments. 



The National Aniline & Chemical Co., Inc., New York 

 City, manufacturer of dyestuffs and miscellaneous coal tar prod- 

 ucts, has issued a handsome 24-page illustrated booklet containing 

 a very readable brief history of the development of the American 

 dyestuff industry, showing the important place this firm occupies 

 in that field and presenting much information regarding its serv- 

 ice and products for the treatment of textiles and rubber. The 

 list of intermediates and other coal tar derivatives includes sev- 

 eral accelerators, notably aniline oil and thiocarbanilide, much 

 used in rubber manufacture. 



"Carspring," the latest catalog of belting and cotton 

 ' rubber-lined fire hose, published by the New Jersey Car Spring & 



Rubber Co., Inc., Jersey City, New Jersey, serves for a reference 

 book as well as a catalog. It includes a technical discussion in 

 regard to the construction of belts, together with data compiled 

 from a series of tests made at Stevens Institute of Technology, 

 Hoboken, New Jersey, and offers in handy form some valuable 

 information for plant engineers and students of belting efficiency. 

 The booklet is attractively printed in two colors and is adequately 

 illustrated. 



.The illustrated c.\talog of the Davol Rubber Co., Provi- 

 dence, Rhode Island, is said to present the most complete line 

 of druggists' sundries, hospital and stationers' rubber goods on 

 the market today. It is printed on fine quality paper, profusely 

 illustrated with cuts in color and black and white, and will be 

 found by the buyer superior in many respects to a line of samples. 



An ATTRAcrrivE folder entitled "The A B C's of Refrigera- 

 tion," issued by The Technical Products Co., 501 Fifth avenue.

A NEW PUDLIC.VTION, OF WHICH VOLUME I, NuMBER 1, H.\S JUST 



come to the Editor's desk, is The Planter, an illustrated monthlj 

 paper, official journal of The Incorporated Society of Planters, 

 and published by them at Kuala Lumpur, Federated Malay States. 

 .As is but natural, the magazine is devoted mostly to rubber 

 culture and its constant problems and activities, but its lighter 

 side shows the characteristic trait of the Englishman to take 

 his sports and his jests with him wherever he goes. The August 

 issue contains among others, articles on "The Future of Rub- 

 ber," "Brown Bast — the Mystery Still Unsolved," and "Sugar 

 in Malaya." We wish success to The Planter. 



"Commercial VEiiia.ES of Great Britain, Volume II, 1920," 

 published by The B. F. Goodrich Co., Limited, London, England, 

 contains complete specifications of various types of trucks, char-a- 

 bancs, etc., arranged to be of great value to manufacturers, deal- 

 ers and users of commercial vehicles. Upwards of a hundred types 

 of vehicles are considered, ranging from J4 to 6 tons normal 

 capacity, or to 10 tons when used with trailer. 



.'Analysis of the various tire sizes used shows that out of six 

 Ij'i-ton trucks considered, three preferred front tires measuring 

 S60 by 90 mm. single (or 90 to 720 mm. rim), while three also 

 agreed upon rear tires 860 by 90 mm. twin. In 2-ton trucks six 

 out of twelve analyzed called for front tires 870 by 100 mm. or 

 100 for 720 rims single, and rear tires twin of same dimensions. 

 The same dimensions of tires were also popular with four out of 

 seven 2J^-ton trucks analyzed. Three-ton trucks showed more 

 diversity in tire sizes, five out of seventeen using front tires 900 

 by 120 mm. or 120 for 720 mm. rims, while only two used the 

 same rear tire size, 103 by 140 or 140 for 851 twin. Three VA- 

 ton commercial vehicles used front and rear tires the same size, 

 930 by 120 mm. or 120 for 771-mm. rims, the remainder of the 

 eleven analyzed calling for many different tire sizes. Among the 

 4-ton trucks, tire sizes varied still more, three preferring front 

 tires 900 by 130 mm. or 130 for 720 rims, and two each front tires 

 900 by 120 or 120 for 770 riins, and 880 by 120 or 120 for 720-mm. 

 rims. Rear tires 1,010 by 120 mm. or 120 for 850 were chosen by 

 two 4-ton trucks, while two others agreed upon 1,050 by 120 or 

 120 for 881. 



The others among the nineteen 4-ton trucks analyzed showed 

 wide variations, .\mong eighteen types of S-ton trucks there was 

 more uniformity. Three each used front tires 900 by 160 or 160, 

 for 720-mm. rims, and 880 by 120 or 120 for 720-mm. rims. For 

 rear tires five used 1,050 by 160 twin or 160 for 850, and four 

 used 1,030 by 140 twin or 140 for 850. Out of five 6-ton vehicles 

 two used front tires 970 by 160 or 160 for 771 and rear tires 

 1.050 by 160 or 160 for 850-mm. rims.
