Abstract

1401438 Joint making packing DUNLOP Ltd 20 Oct 1972 [30 Oct 1971] 50552/71 Heading F2B An inflatable seal 10 for sealing the gap 23 between two members 12, 213 of, e.g. an autoclave, comprises a relatively flexible expander section 14 for location in a groove 11 in one of the members and a relatively rigid sealing section 15 movable, on inflation of the seal, Fig. 2, into engagement with the other member. The seal is made of rubber and reinforced by fabric 22 and its sides 18 and 19 are corrugated. A connection (not shown) is provided for the supply of pressurized liquid or gas to the inflation chamber 20 to inflate the seal. To retain the seal in its groove 11 the base portion 17 is a tight fit in the bottom of groove. Alternatively, one or both sides of the groove may be undercut to accommodate in ridge or ridges on the seal or the seal may be formed with a groove engageable with a ridge in the groove 11. The seal may be in the form of a ring closed at both ends.
