RUBBER IN AIRCRAFT CONSTRUCTION. 



IN a lecture recently delivered before the Aeronautical Society. 

 ■"■ London, Captain G. S. Walpole remarked that materials, other 

 llian metal, used in aeronautics were less satisfactory, owing to 

 the fact that they are more easily influenced by time, temperature 

 and humidity, and that the best results cannot be obtained with 

 the same directness and precision of forecast. 



He showed that in such rubber parts as shock-absorbing devices 

 and tires in airplanes, not only shape, size and arrangement were 

 to be considered, but also the coinposition and properties of the 

 material. In this connection, he complained of the lack of co- 

 operation between rubber manufacturers and aircraft designers, 

 instancing the ignorance of manufacturers as to the work re- 

 (piired of .shock-absorbers. The ideal shock-absorber, he asserted, 

 should be like a "pudding," which gives to a load and slowly re- 

 sumes its shape. Steel springs are unsuitable, because when 

 loaded, they "hit" back at once. He also considered the possi- 

 liility of obtaining increased shock-absorbing power from shock- 

 absorber rings by employing different rubber mixtures, discussed 

 the use of rublier for conveying petrol, oil, and hot water, and 

 described the rubber-proofing of fabric for balloons. Tests of 

 airplane tires were shown on slides, one wheel having been 

 loaded to .S tons, which caused the spokes to collapse, but 

 did not affect the tire. 



In dealing with other materials, he discussed the development 

 of the waterproof form of "fiber," and remarked that the ordi- 

 nary form is not isotropic, but has markedly different properties 

 towards humidity in two directions at right angles to each other 

 — a quality to be carefully watched in magneto work. 



THE MARKET FOR CHEMICALS AND COMPOUND- 

 ING INGREDIENTS. 



NEW YORK. 



Copyright iQiy. 

 YY/ ITH the declaration of war came the uncertainty as to what 

 *' the Government will require in base metals. Pig lead has 

 been in great demand and sellers have adopted a waiting policy. 

 Tile inactivity in copper is due to buyers holding off for future 

 developments. Spelter continues to be weak and prices have 

 declined. Tlie antimony market has been dull and prices steady. 



The shipping difficulties that have beset the foreign and do- 

 mestic rubber chemical trade for some time have continued dur- 

 ing tlie past month. There has been a good demand, the many 

 inquiries received by the dealers during April showing that buy- 

 ers are wisely anticipating future requirements. 



China Clay. The steady call, limited supplies and freight 

 diflScuIties have resulted in advanced prices for this material. 



Glue. All the various grades are in demand and higher prices 

 have l)een recorded (hiring the montli.
