Allan Browne has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11124919
    Abstract: A strander apparatus includes a disk and a plurality of cradles, each of the cradles includes a reel and a cradle shaft, the cradle shaft extending in an axial direction from the disk. Each reel dispenses cable. The strander includes a main shaft, wherein the cradles are disposed on the cradle shafts radially about the main shaft. Planetary gears are disposed between the main shaft and the plurality of cradle shafts. The strander operates in one of a planetary mode and a rigid mode. In the planetary mode, while the main shaft rotates, the planetary gears are engaged to rotate each of the plurality of cradles on the respective cradle shafts. In the rigid mode, the planetary gears are disengaged.
    Type: Grant

  • Patent number: 8124673
    Abstract: Low-viscosity drag reducers, systems for delivering low-viscosity drag reducers, and methods of making low-viscosity drag reducers are disclosed. The low-viscosity drag reducers have a viscosity less than 350 cP at a shear rate of 250 sec?1 and a temperature of 60° P. This low-viscosity allows the drag reducers to be delivered through a long and relatively small diameter conduit of a subsea umbilical line without an unacceptable level of pressure drop or plugging of the conduit. The low-viscosity drag reducers can be delivered to a subsea flowline carrying fluids produced from a subterranean formation to 10 thereby provide significant drag reduction in the flow line.
