Abstract: A cutter used to spirally slice a vegetable including a frame; a shaft supported on the frame, the shaft being freely rotatable and movable along an axis; a holder attached at one end of the shaft; a cutting assembly supported opposite the holder having a first annular blade defining a first bore adapted to form a first peel, a cross cutter adapted to break the first peel into a segment, and a second annular blade defining a second bore, wherein the second annular blade is spaced axially outward from the first blade relative to the holder and wherein the second blade has a diameter smaller than a diameter of the first blade and is adapted to cut a second peel from the core left by the first blade.

Abstract: A method of creating a zonal isolation above a target zone in an underground wellbore comprises: inserting a slurry injection tubing into the wellbore; arranging within an annular space surrounding said tubing an particle accumulation means, such as an expandable screen or an area where the slurry velocity is reduced; and pumping a slurry comprising a carrier fluid and granular material down via the slurry injection tubing and the target zone and then up into the annular space, such that at least some granular material accumulates and forms an elongate zonal isolation in the annular space between the target zone and the particle accumulation means, which zonal isolation is removable and exerts a limited radial force to the surrounding formation, thereby reducing the risk of formation damage.
