Abstract
601,278. Refrigerating. YOUNG, T. N., and GLEDHILL, E. G. B. Oct. 12, 1945, No. 26756. [Class 29] [Also in Group XXVIII] Apparatus for temporarily stopping a pipe to effect repairs comprises two closed refrigerating chambers adapted to be assembled round the pipe and each having a charging opening for a refrigerant. The two parts are hinged together by a pin 3 engaging lugs 4, springs 5 normally urging the parts together, the inner walls of the chambers being shaped to fit closely on the pipe or on a two-part liner 41. A series of liners having different internal diameters is provided, and each half liner is flanged and secured by spring-pressed ball catches 48. Each chamber has a charging opening in a side wall and in one of its end walls, closed by interchangeable plugs 14, 18, The chambers are charged with a mixture of solid carbon dioxide and methylated spirit, the plug 14 having a small gas vent 16 and the plug 18 having a safety-valve 19, the plug 14 being arranged in the side or end opening according to whether the pipe is horizontal or vertical. The chambers are secured together by a channelshaped locking bar 23 which engages grooved flanges on the chambers, and carries a handle 24.
