Abstract

20,301. Bugden, T., Martyn, H. C., and Arbon, A. Sept. 12. Stopping pipes and tubes.-To minimize the destructive action of deposits in gas mains on inflatable bags employed for stopping the mains, the elastic inflatable bag is protected by enclosure in another bag of some non-elastic flexible material which resists the action of the deposits. Holes may be provided in the outer bag for the escape and entrance of air during inflation and deflation. The inflating- tube c is connected to the inner bag by a rubber disk e, which is securedto the tube c and cemented to the inner bag b. The outer bag a extends a short distance over this rubber disk e, and an outer disk f of rubber cloth is cemented to the disk e and sewn to the bag a.
