Abstract: A hand operated tool used to remove the burr from the inside end of a cut metal pipe comprising two rollers adapted to be placed inside the end of a pipe, means to expand the rollers with a hand squeezing motion on the handles of the tool and rotating the pipe or tool until the burr is rolled outward making the inside of the pipe free of any obstructions.

Abstract: The invention involves a method and compositions for cleaning all oily, natural or synthetic stains or residue from any stone surface, natural or man-made. The method comprises surrounding the stain with a container which is open at the bottom, pouring in a solvent material, covering the container with an airtight lid to prevent evaporation and allowing the solvent to remain on the stain for from 1 to 24 hours. Thereafter the lid is removed and an adsorbent powder is added to the container to the top of the absorbent liquid. The absorbent powder is allowed to stand for 1 to 24 hours and then the powder is removed and the surface being cleaned is allowed to air dry for 24 hours.
