  • Patent number: 9546759
    Abstract: Natural gas is produced when LNG that is contained in an insulated LNG cargo tank(s) of a non-self-propelled LNG carrier (i.e., a barge) evaporates as a result of heat leakage through the walls of the insulated cargo tank(s). The natural gas is transferred from the barge to a tugboat or a towboat that is equipped with natural gas burning engines through a flexible gas transfer assembly so that the tugboat is powered by the natural gas fuel. The pressure in the cargo tank(s) on the barge is, therefore, effectively managed to prevent or substantially reduce the buildup of pressure within the LNG cargo tank(s). The LNG can then be contained within the LNG cargo tank(s) for an appropriate period of time and can be delivered at an appropriate and acceptable equilibrium pressure and temperature.

  • Patent number: 6053790
    Abstract: A flotation device carries two or more people down a waterslide on shaped flotation tubes, coupled by flexible straps into a train. The bows and the sterns of adjacent buoyant bodies are complementarily shaped, preferably the bow being circularly convex and the stern concave as viewed in plan. The straps hold the bow and stern together at a minimal gap, constraining relative rotation by the convex/concave engagement of the bow and stern. In addition, lateral shoulders on the bow abut against the ends of the concave stern to prevent rotation beyond a predetermined angle, for example wherein the bodies in the train are relatively rotated to a bend having about a ten foot radius. This structure provides sufficient flexibility to traverse relatively tight turns in the waterslide course while preventing buckling or accordion-fold collapse when the train of buoyant bodies encounter an obstruction such as a splash down pool.
