  • Patent number: 8408047
    Abstract: A universal adapter to be detachably connected to the round fuel cap retaining lip of most any fuel tank filler neck so that smoke (i.e., a vapor) under pressure can be delivered to the fuel tank of a motor vehicle to test the fuel system for leaks. When connected, the universal adapter lies entirely outside the fuel tank filler neck. The universal adapter includes a circular ring-shaped rim that is manufactured from a flexible material having a spring memory. The flexible rim of the universal adapter is stretched and attached in surrounding sealing engagement against the fuel cap retaining lip of the filler neck. The universal adapter also includes a vapor inlet tube to which the nozzle of a vapor supply hose is attached. According to one embodiment, smoke produced by a smoke-generating machine pressurizes the fuel tank by way of a vapor delivery path which includes the vapor inlet tube of the universal adapter and the fuel tank filler neck of the motor vehicle.

  • Patent number: 4066098
    Abstract: An articulated branch assembly comprising pipe member and appropriately arranged combinations of fluid carrying swivels, ball joints, or rubber hose is fixed to the outboard end of a conventional marine cargo loading arm. The branch assembly is used for bunkering vessels while the arm is supported off the cargo manifold adjacent to the bunker manifold. Fitting marine cargo arms with the bunkering assembly and supporting the arm off the cargo manifold permits, for a large percentage of vessels, simultaneous bunkering and cargo transfer through the other cargo arms in the bank. The branch assembly also: eliminates in many cases the need for a separate bunker arm(s), avoids overstressing of the smaller, weaker bunker manifolds, and makes the bunker manifolds more accessible without resorting to long lengths of hose or auxiliary bunkering saddles.
