Abstract

1,208,420. Pipe couplings. HALL THERMOTANK INTERNATIONAL Ltd. 13 March, 1968 [13 Dec., 1966], No. 55687/66. Heading F2G. An air duct 1 for coupling an inlet or outlet port 4 of a cargo container 2 comprises a rigid tubular nose unit 3, which may be frustoconical or cylindrical, having a circumferential groove 6 in which is disposed a hollow, inflatable; annular gasket, and a shut-off valve 9 connected by a pressurizing pipe 8 to the gasket. The gasket may be expanded into a groove 7 in the wall of the container, and the unit 3 may have a locating flange 10 and incorporate a heating element for defrosting the unit. The valve may be a three-way valve, or a non-return valve combined with means to render the. valve bi-directional or a separate pressure release valve.
