摘要： A method and apparatus for mining of hydrocarbons from a hydrocarbon-containing clathrate such as is found on the ocean floor. The hydrocarbon containing clathrate is disaggregated from sediment by first disrupting clathrate-containing strata using continuous mining means such as a rotary tilling drum, a fluid injector, or a drill. The clathrate-rich portion of sediment thus disrupted from the sea floor strata are carried through the apparatus to regions of relative lower pressure and/or relative higher temperature where the clathrate further dissociates into component hydrocarbons and water. The hydrocarbon is recovered with the assistance of a gas that is injected and buoys the hydrocarbon containing clathrate helping it to rise to regions of lower pressure and temperature where hydrocarbon is released. The sediment separated from the hydrocarbon returns to the ocean floor.

摘要： A dredge supporting a pivotal ladder with a suction auger on its free end. A shroud assembly including front, center and rear sections surrounds a large portion of the periphery of the auger. The shroud assembly is pivotal about the axis of the auger and the front and rear sections are each independently pivotal relative to the center section so that the center section can be maintained at a relatively constant attitude independent of the inclination of the ladder and only a leading one of the front and rear sections, depending on the direction of movement of the dredge, is necessarily opened while the trailing section can remain closed adjacent to the auger. The articulation of the several shroud sections enables the suction auger head to operate in both directions with reduced turbidity and, therefore, increased efficiency.

摘要： An excavator is provided with a box type casing including a pair of rotary cutters mounted on the bottom portion of the casing; blades provided at the outer periphery of the cutters provide excavating action with soil so excavated being discharged through a discharging tube having a sucking port around the rotary cutters; further provision being made for slide cutters on the periphery of the casing. In operation the inter action of the rotary cutters provides discrete and alternate ditch bores whereafter the areas between the ditch bores are excavated to form a ditch of desired length and width.
