The rubber industry has matched operating efficiency, and increased the 1933 progress of the can mukers; danger. by a major advancement in tube- making, eliminating the customary air leakage of two- to five pounds per week.
This new development by research engineers of the Firestone Tire & Rubber Company, is known as the Sealty te-Lenkproof tube. It has a tapered rubber valve stem, and the inside of the inner tube is coated
with a composition that seals the pares of the rubber.
The importance of immer tubes has not always been fully realized, al- though in some countries tubes are! considered so important they are called "tyres " as distinguished frum casinge" Inflation pres sure, the chief factor in safety and mileage, is dependent upon tubes.
