Abstract
586,225. Refrigerating apparatus. YOUNG, T. N., and GLEDHILL, E. G. B. Nov. 3, 1944, Nos. 21567/44 and 3456/45. [Class 29] [Also in Group XXVIII] A portable device for temporarily freezing a short length of liquid-containing pipe so as to effect repairs comprises refrigerating apparatus including a power-unit and a compressor for the refrigerant and means for circulating the refrigerant through a chamber adapted to be assembled around the pipe. The chamber which with its flexible connections is normally mounted on the portable casing of the power-unit and compressor comprises semi-cylindrical parts 11, 12 hinged together at 13 and having inner cylindrical surfaces 20, 21 which are adapted to be clamped on to the pipe by a bolt 14. The flexible refrigerant supply pipe 7 is connected to a rigid inlet tube 23 secured on the chamber and containing a coiled tube 24 through which the refrigerant is delivered to the evaporated chamber 25. The refrigerant passes through passages 28, 33 and the bore 30 of the hinge to the lower expansion chamber 27 and back to the compressor through a flexible pipe 6. Insulating casings 39, 40 are provided and the device is adapted for pipes of different sizes by the provision of two-part liners having end flanges which engage ball catches (not shown) in an end face of the chamber. In a modification the refrigerant is admitted to the upper evaporating chamber through a spring-pressed valve, the upper and lower chambers being connected by a flexible pipe. In a further modification the evaporating chambers are arranged in parallel, the refrigerant being divided into two streams one passing through each chamber the streams being united on leaving the chambers. Specification 586,228, [Group XXVIII], is referred to.
