Abstract: The apparatus for extracting a tree stump from the ground without the root has a frame including locating means for locating the frame in a predetermined central position on a tree stump. Shearing means oppositely disposed on the frame are pivotable toward each other to cut the tap root of the tree stump in a lateral direction at a predetermined distance below the ground level. The shearing means are pivotable by a first set of hydraulic cylinders and also receive additional movement from a thrust member that moves longitudinally with respect to the frame and engages the shearing members during such longitudinal movement. The thrust member also includes an annular cutter portion for cutting the lateral root of the tree stump substantially simultaneously as the shearing members cut the tap root. In one embodiment of the invention the cutter blades of the shearing members are placed next to each other in substantially continuous line to line contact after total shearing of the tap root of the tree stump.

Abstract: This invention relates to an improved method for the production of high purity dicumyl peroxide. As produced, dicumyl peroxide contains many impurities which must be removed. Generally, our invention comprises flash distilling crude dicumyl peroxide, separating and discarding the distillate and allowing the residual product to crystallize. The supernatant liquid from the crystallized dicumyl peroxide is then fed into the next batch of crude dicumyl peroxide to be distilled. In this manner high yields are obtained along with a very rapid distillation time. Because the supernatant liquid from each crystallization is fed back into the process, the dicumyl peroxide normally left in the supernatant is recovered in the subsequent steps.
