Abstract
758,388. Joint-making packing. DUNLOP RUBBER CO., Ltd. Jan. 31, 1955 [Feb. 13, 1954], No. 4290/54. Class 122(3) [Also in Group V] An inflatable pressure seal for use in an aircraft, particularly for preventing loss of pressure from around the edges of a cockpit canopy or of a door or other opening in a pressurized fuselage, is made by securing a vulcanizable base portion 3 and resilient bead portion 4 at diametrically opposite locations to a vulcanizable fluid-tight tubular portion 1 and vulcanizing the assembly when in a collapsed condition as in Fig. 2. The base portion 3 which is intended for fitting along the edges of the cockpit or of the door opening may be formed from a channel-shaped extrusion while the resilient strip 4 is adapted on inflation of the portion 1 to engage with the edges of the cockpit canopy or of the door, and may have a passage 6 extending longitudinally therethrough. The parts 1, 3, 4, which are of natural or synthetic rubber, are secured by adhesive and the whole assembly placed in a mould and vulcanized, air being blown at the same time through the portion 1 to prevent the two halves from sticking together. The portion 1 may have an outer reinforcement 2 of woven fabric. The part 4 may be of soft. rubber, the passage 6 then being omitted.
