Abstract

329,401. Ball, F. L., Moulton, F., and Lead Wool Co., Ltd. Feb. 22, 1929. Indicating leaks. - Apparatus, in which the ends of a cylinder 4, arranged inside the joint 3 to be tested, are sealed by inflatable tubes 9 to form an annular space for the testing fluid, is centred by screws 15. The tubes 9 are supported by members 6, which are either angle or T in section, and are drawn together by bolts 13 or detachable clamps, and, in the case of large pipes, flat plates extending, to the pipe surface are inserted between the members 6 and the tubes 9; the plates or the members 6 may be shaped to fit the tubes 9 and the whole apparatus may be sectioned circumferentially to facilitate erection. Each tube 9 comprises an inner openended rubber tube 23 which is inserted into a tube 24 built up of alternate layers of rubber and canvas; the ends of the inner or outer tubes are then joined by lap and scarf joints respectively. Specification 212,715 is referred to.
