Abstract: A free-standing overhead fan apparatus includes a stand and a fan mounted on the stand. The stand includes a base positioned on ground level and an elongated member extending upwardly from the base. The fan is mounted at the upper end of the elongated member, preferably about seven feet above ground level. The fan includes a housing containing an electric motor and a rotating shaft extending from the motor. The fan also includes fan blades radially extending from the motor shaft. The fan is mounted on the stand such that the motor shaft and fan blades are rotatable about a vertical axis to emulate a ceiling fan.

Abstract: 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.
