摘要： A watertight vertically elongated rigid shell or hull of a size small enough to be transportable over highways has a detachable snorkle extending from its top and contains a power source which may be used to drive pumps within the device and/or to drive mechanical devices, such as rotating blades, winches, belts, drills or propellers, which are located externally of the hull. The hull of the device is divided into upper and lower compartments, of which the lower compartment can be completely or partially flooded with water which acts as a ballast helping to stabilize the device and controlling submersion thereof and its submerged position.

摘要： Staged combustion apparatus is disclosed for generating repetitive explosions. The apparatus includes a first chamber in which a gas under pressure is ignited by an ignition source, such as a spark plug, and a second chamber in which gas under pressure is ignited by gas discharging from the first chamber. The second chamber includes a discharge outlet and a dump valve is provided responsive to the gas pressures in the two chambers for permitting the discharge of gas under pressure from the second chamber when it is ignited. The gas discharge, for example, may be conducted about the tooth of a ripper plow to aid in earth fracture.

摘要： The sea sled includes a pair of pontoons mounting depending rollers for straddling a pipeline disposed on the sea bottom. Water jets fluidize the sea bottom to form a trench in which the pipeline settles. The slurry formed by the water jets is removed from the trench by the eductor system which includes a pair of conduits each having a suction inlet at its lower end for location within the trench, a discharge at its upper end, a pair of pump nozzles each having an inlet external to the associated conduit and an outlet within the conduit directed toward the corresponding discharge, and a pair of primary nozzles, the outlet ends of which respectively project into the inlet ends of the pump nozzles. A high pressure, low volume, fluid is pumped from the surface through the jet nozzles. Ambient fluid is entrained with the high pressure, low volume fluid emanating from the jet nozzles in the respective pump nozzles to deliver low pressure, high volume fluid to their corresponding discharges. The action of the pump nozzles in the conduits creates a suction whereby the slurry from the trench is pumped from the trench through the conduits and discharged to opposite sides of the trench.

摘要： A generally horizontal, perforated pipe extends across the bottom of a waterway to be dredged and, in some embodiments, is connected to a suction pump above the water level. The perforations in the horizontal pipe are cleaned of debris by a plurality of horizontal nozzles supplied with water under high pressure which direct high velocity water streams across each perforation to mix with sand along the bottom of the waterway and thereby abrade any obstructions which have settled over the perforations.

摘要： A system for gathering solids disposed on the ocean floor by dragging a collecting apparatus along the ocean floor so as to deposit the solids in an extended pile, the collecting apparatus having a relatively large inlet opening and a relatively small exit opening. The solids are brought to the surface by conveying apparatus that draws the solids from the pile and drives them up to the surface, the conveying apparatus being independent of the collecting apparatus.

摘要： A tractor includes an internal combustion engine and is adapted for underwater operation, with inlet and outlet means extending to above the surface of the water for supplying air to the engine and exhausting combustion gas therefrom. A dredging implement in the form of a blade and auger, directs material from the floor to adjacent one end of a conduit means as the vehicle is transported over the floor. An impeller associated with the conduit means transports the material therethrough and from the other end of the conduit means, which is positioned above the surface of the water. The dredging implement may alternatively take the form of a pair of wing members, each angled upwardly and inwardly in the rearward direction to direct material to adjacent the one end of the conduit means. Means remote from the vehicle, and positionable on shore, are included for operating the submerged tractor.

摘要： A system of subaqueous excavation and material removal having the combination of a hopper dredging vessel, hopper barges with independent dumping capacity and a prime mover vessel such as a tug, each barge having a stern notch and a bow portion which is contoured to be received in a like stern notch of an adjacent barge so that two or more barges can be arranged and affixed into an assemblage, end-to-end with bow portions fitting and secured into the stern notches. The dredging vessel and prime mover vessel also have like bow portions whereby they can connect into the assemblage. Rapid and effective securing of the assemblage, the dredging vessel and prime mover vessel are obtained through pneumatic fenders attached to the sides of the stern notches and a pneumatically controlled cushioning fender couple attached to the stem which is received between vertical expansible fenders at the apex of the stern notch. By expansion of the fender couple and the apex fenders, the vessel is effectively secured to the assemblage. In order to separate the assemblage and the vessel, the fender couple and the tubular members are deflated. Conduits to carry dredged material are located on each barge and the dredging vessel. Each has a tubular outlet extending proximate the bow portion which is received in a larger tubular inlet extending proximate the stern notch, there being an arrangement of annular members about the engaging conduits which are expansible and securely connect the conduits together whereby dredged material may be delivered from the dredging vessel simultaneously to each of the barges in the assemblage.

摘要： A submarine dredge comprises a rotatable bucket wheel surmounted by a hood. Compressed air is fed beneath the hood so that the water level beneath the hood is maintained a substantial distance below the high point of the path of the buckets. As a result, the buckets discharge into air much more readily than they would discharge if totally submerged. The solids discharged from the bucket are caught in a hopper within the wheel, and means are provided to supply water to the hopper so that a water-soil mixture can be removed by suction. Water jets are played into the buckets to assist discharge therefrom and the jets are controlled visually either remotely or directly.
摘要翻译： 海底挖泥船包括一个由发动机罩覆盖的可旋转斗轮。 压缩空气在发动机罩下方进给，使得罩下方的水位保持在低于桶的路径高点的相当距离。 因此，如果水桶完全浸没，排放比排放更容易。 从铲斗排出的固体被捕获在车轮内的料斗中，并且提供装置以向料斗供水，以便可以通过抽吸去除水土混合物。 将水喷射到铲斗中以帮助排放，并且可以远程地或直接地控制射流。
