Abstract: A pass-through device for internalized component fuel tanks provides passageways for communication between the interior chamber of the fuel tank and the exterior. The pass-through device includes a communicative passageway for a fuel supply line and a through opening for electrical connections, and may include additional communicative passageways for fuel return lines, and purge and fresh air inlets. The pass-through device includes a main body preferably composed of nylon. The main body is bonded to a mounting plate preferably composed of polyethylene. The mounting plate provides a circumferential surface for weldably sealing the pass-through device to a polymeric fuel tank.

Abstract: A foldable walker (10) includes a first pair of opposed legs (14,16) and a second pair of opposed legs (13,15). A housing (25) is positioned between the first pair of legs (14,16). The housing (25) carries a lock/release mechanism (35) that includes a depressible button (36). The button (36) is connected to levers (45,47) such that when the button (36) is depressed, the levers (45,47) rotate to translate rods (51,53), respectively. When the rods (51,53) are so moved, pawls (68) connected to the rods (51,53) are rotated out of their normal engagement with bosses (60) carried by the first pair of legs (14,16). The first pair of legs (14,16) may then be rotated with respect to the housing (25) so that the second pair of legs (13,15) are positioned adjacent to each other and to the housing (25).

Abstract: A chair (10) having adjustable height includes a seat (11) and a number of leg members (12). An adjusting mechanism (30) includes an insert sleeve (40) received within a hollow area (31) of a leg member (12). The insert sleeve (40) has an internal thread (52) which threadably receives a leg extension (60) having an external thread (61). Rotation of the leg extension (60) within the sleeve (40) adjusts the length of the leg member (12).
