JUDICIAL DECISIONS. 



/^ENERAL Electric Co. vs. Continental Fibre Co.— United 

 ^^ States Circuit Court of Appeals, Second Circuit, February 

 13, 1919. 



Infringement of Patent No. 1,061,770. Miller made a gear 

 or cog-wheel of highly compressed cotton, held under com- 

 pression by metallic end plates secured by rivets passing through 

 the cotton. Defendant makes disks of cotton duck impregnated 

 with bakelite, 60 per cent duck and 40 per cent bakelite, which 

 can be cut into gears. Held that, when used for gears, it vio- 

 lated Miller's Patent. ("The Official Gazette," United States 

 Patent Office, November 4, 1919.) ("Federal Reporter," Vol- 

 ume 256, page 660.) 



High Court of Justice — Chancery Division. Before Mr. Jus- 

 tice Sargant. November 13, 1919. 



In the matter of Muir's Patent. Petition for extension. This 

 is a device for absorbing the shock to a vehicle from striking 

 the road, by means of arranging a vacant space around the 

 hub, which is partly filled with balls or rollers or other forms 

 of wood or metal. The hub may be cushioned with rubber or 

 other resilient substance. The invention may do away with 

 the need for pneumatic tires and is now employed on motor 

 omnibuses, motor trucks and on heavy cars, so that solid rubber 

 tires may be fitted instead of pneumatic tires. The Court ex- 

 tended the patent for seven years. ("Supplement, The Illus- 

 trated Official Journal [Patents]," London, England, December 

 17, 1919.)

CHEMISTS AVAILABLE FOR RUBBER WORK. 



The Chemical Warfare Service of the War Department has 

 ■established an employment bureau under the charge of Major 

 Frederick M. Crossett as director, which is ready to supply 

 skilled chemists to any business that requires their services. 



The Government employed 5,400 chemists during the war, 

 who could not hope to obtain honors or distinction for their 

 work. Many of these are unable to go back to the work they 

 did before, owing to the changed conditions. The director has 

 a list of chemists who can be used in the rubber industries.

On the Mutual Motors Co. becoming bankrupt, the Firestone 

 Tire & Rubber Co. endeavored to regain tires and other rubber 

 goods that were in the possession of the Mutual Motors Co., 

 claiming that they had been sold on consignment. The Court, 

 Tuttle, J., delivering the opinion, held that the sale was absolute. 

 Petition not granted. ("Federal Reporter," Volume 260, page 

 341.) 



THE METRIC SYSTEM EXPLAINED. 



Learn only the units, dollar, meter, liter, gram — dollar, the 

 measure of value; meter, the measure of length; liter, measure 

 of bulk ; gram, for weight. You know all about the American 

 dollar. The metric units, meter, liter, gram, are just like dol- 

 Ijr, divided decimally and multiplied decimally. If you want to 

 compare metric units with present units, the meter is 10 per 

 cent more than the yard ; 500 grams is about 10 per cent more 

 than the pound avoirdupois, the lifer is 5 per cent less than the 

 United States liquid quart (13 per cent less than the British 

 liquid quart).
