An adapter for connecting a separated-outlet fluid cartridge to a single-inlet static mixer includes a lock mechanism and a lock release mechanism. The adapter includes a connection portion that engages the mixer. The lock mechanism has at least one snap arm that lockingly engages the cartridge in a snap fit manner so as to secure the adapter to the cartridge in fluid communication. When in the locked position, separate fluids are evacuated from the cartridge into the mixer where they are mixed prior to dispensing. The lock release mechanism quickly and easily unlocks the at least one snap arm from the cartridge for allowing a user to separate the adapter from the cartridge. The adapter sealing engages with both the mixer and the cartridge so that fluid flowing from the cartridge to the mixer does not leak.

An apparatus and method for installing an aircraft bulkhead connector with a bulkhead is disclosed where access to only one side of the bulkhead is required. The disclosure is also applicable to installation of bulkhead connectors in aircraft fuel tanks. An aircraft bulkhead connector and installation tool is also disclosed. The bulkhead connector includes a female end portion and the installation tool includes a male end portion. The male end portion of the installation tool is removably engaged with the female end portion of the bulkhead connector, such that the installation tool protrudes beyond the female end portion of the bulkhead connector. The installation tool may be inserted through an aperture in a bulkhead and used to both position and hold the bulkhead connector during the installation process.

A method of joining fiberglass-reinforced composite pipes includes joining an inner tube of each pipe by fusion to form a fused bond, joining fiber reinforced polymer tubes of each pipe by depositing a silica glass particle epoxy directly on the fused bond and on bonded edges of the fiber reinforced polymer tubes as a composition to cover tube edges and the fused inner tube bond, and curing the composition.

A fluorine gas functionalized surface of a fixture is chemically bonded to a fiberglass sump using a resin. The resin chemically reacts with the functionalized surface creating a strong, chemical bond between the fixture, which penetrates the shell of the sump, and the fiberglass shell of the sump. For example, the surface of the fixture is functionalized by a fluorine-containing gas mixture in an autoclave at a temperature, pressure and duration that creates CO double bonds at the surface of a polyethylene fixture. The resin chemically reacts with the CO double bonds and bonds with a fiberglass transition fitting capable of being joined to the shell of the sump.

A system for connection between parts of a structure, comprising providing the parts (1, 2, 3 and 4) to be connected with elements in the form of ribs or drill holes (5), on the surfaces of zones or areas of connection of said parts; placing the parts to be connected in a mold (7), in the relative position they will occupy within the structure, with the ribs or drill holes (5) inside said mold; and injecting, into the mold, a resin or melted adhesive plastic such that it fills the drill holes (5), the inner holes of the parts and the spaces (8) defined therebetween.
