Abstract: 760,908. Bolted and riveted joints. NORTH AMERICAN AVIATION, Inc. Dec. 23, 1954, No. 37297/54. Class 83 (4). [Also in Group XXVI] A method of sealing a bolted or riveted joint in, e.g. aircraft fuel tanks, boat or seaplane hulls, comprises providing an elongated shallow recess of constant width in one of the joint members along the line of the bolts or rivets, said recess encompassing the bolt or rivet holes, providing an opening from the exterior of one of said members communicating with said recess, and injecting a sealing material into said recess to seal the joint. An aircraft fuel tank comprises the skin 2 of the wing, a supporting beam 3 having an enlarged opening 5, and a bulkhead 4. The skin is bolted or riveted to flanges on the beam 3 and bulkhead 4 and to seal each joint a channel 17 is provided in the surface 18 of each flange 12 for retaining a sealing material, e.g. a non- hardening polysulphide synthetic rubber. The channel is enlarged as at 17a to encompass the bolts or rivets. The sealing material is injected through an aperture 19 and to retain the material in the channel the faying surfaces of one or both of the members is provided with a coating 20 of non-hardening accelerated synthetic rubber comprised of an organic polysulphide liquid polymer. The coating may be disposed on one or both sides of the groove. A second aperture may be provided to indicate whether adequate sealing material has been injected and also to permit air to escape from the channel. If the joint is long a number of apertures may be provided. In a modification the sealing channel is of constant width. At the corners of the tank one edge 34 (Figs. 11 and 12) of side 33 engages surface 35 of adjoining side 36. Also, side 37 mates with the top surfaces 38 of side 36 and with surface 39 of side 33. To seal the joints groove 17x in surface 34 opens into groove 17y in top edge 39 of this side. The latter groove continues into member 36 where it meets groove 17z. After the sides are bolted or riveted together sealing material is injected through apertures 40, 41 and 42. Barrier material 20 is interposed between all three of the sides at the corner. A modified form of barrier comprises a thin aluminium wire 44 (Fig. 13), disposed between the faying surfaces at the outside portion of the joint, the wire being deformed when the joint is tightened up. The surfaces in this modification may also be coated with synthetic rubber. By providing more exacting manufacturing tolerances the barrier seal may be dispensed with.

Abstract: 1,103,554. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 31 Aug., 1965 [14 Sept., 1964], No. 37439/64. Heading B7K. An air cushion vehicle has an inflatable skirt 5 with regions of different stiffness. The stiffness of the skirt may be increased locally by bonded ribs 20 of hard rubber to the outside, as shown, or inside of the skirt. These ribs may each lie in a vertical plane, or may be inclined, e.g. at 45 degrees to the vertical. Alternatively ribs may extend along the bottom of the skirt in a broken line parallel to the periphery of the cushion (Fig. 12, not shown). These ribs are wedge-shaped in cross-section so that air leaving the cushion is detached from the skirt. In another embodiment (Figs. 6 and 7, not shown), inflatable ribs are bonded to the inner surface of the skirt, and lie in a vertical plane. In a further embodiment, the lower part of the skirt is attached to the body by lines which are in tension when the skirt is inflated, thus stiffening the skirt material locally, and a peripheral nozzle may be provided in the skirt in the region of the ties (Figs. 8 and 9, not shown). The skirt may be stiffened by attaching rubber, button-like members to the inside or outside of the skirt (Fig. 14, not shown), or alternatively it may be fabricated of alternate strips of relatively thick and relatively thin material (Fig. 13, not shown).
