Abstract: A tool for removing a portion of a casing from a wellbore. The tool includes a base having an opening or bore formed therethrough. A plurality of hydraulic cylinders may each have a first end portion coupled to the base and a second end portion distal the base. A first crane may be coupled to the base. A tong may be coupled to the first crane, and the first crane may be adapted to move the tong into alignment with the opening in the base. A second crane may be coupled to the base. An attachment may be coupled to the second crane, and the second crane may be adapted to move the attachment into alignment with the opening in the base and proximate the second end portions of the cylinders.

Abstract: A method for reducing the amount of asparagine, a pre-cursor of acrylamide, in food products that are thermally processed. This invention permits the production of foods having significantly reduced levels of acrylamide. The method relies on contacting a potato feed such as potato slices containing asparagine, an acrylamide pre-cursor, with a leaching solution to extract asparagine out of the potato feed. Thermally processing the leached potatoes will result in a potato product having a lower level of acrylamide than a non-leached, thermally processed potato product.

Abstract: Cell walls having asparagine are weakened by one or more cell weakening mechanisms to permit penetration of one or more acrylamide-reducing agents into the cell walls prior to cooking in order to reduce the formation of acrylamide. The methods disclosed herein are especially applicable to sliced food products such as sliced potatoes. Alternatively, the mechanism can be applied to non-sliced foods such as cocoa beans and roasted coffee beans. The cell weakening mechanisms can include microwave energy, ultrasonic energy, pulsed or constant pressure differentials, a cell weakening enzyme, and lime.
