Abstract

586,226. Refrigerating systems. YOUNG, T. N., and GLEDHILL, E. G. B. Dec. 18, 1944, No. 25357. [Class 29] [Also in Group XXVIII] Apparatus for temporarily stopping a liquidcontaining pipe in order to effect repairs comprises means for forming an ice plug including a container formed in two parts 1, 2 hinged together at 5 which is adapted to be assembled around the pipe to hold a charge of a refrigerant such as solid carbon dioxide which makes contact with the pipe. Split gaskets 12 are located in grooves in the sides of the chamber and closely encircle the pipe. Solid carbon dioxide is placed in the chamber before the parts are secured together by the clamping bolt 9, and methylated spirit is introduced through the charging funnel 14 to enhance the cooling effect, gaseous carbon dioxide evolved being allowed to escape through a cock 17. An insulating jacket 18 is provided. In a modification the parts of the cylindrical chamber are arranged so that the pipe is eccentric to the chamber, and after the larger half of the chamber has been packed with refrigerant it is inverted to effect refrigeration. A perforated tube extending through the chamber contains a drying agent. Two-part metal liners may be inserted within the chamber to accommodate pipes of a different diameter. Specifications 586,225 and 586,228, [Group XXVIII], are referred to.
