    摘要： A thread restoration tool (10), including: a first (30A) and second (30B) jaw, being horizontally rotatable (72B) one in relation to the other, for gripping the thread (22) in between; at least one knife (20A, 20B), extending from at least one of the first (30A) and second (30B) jaws, for being inserted into the thread (22) by the gripping; a vertical to horizontal convertor (208), for converting vertical motion of a vertically positioned rod (36) to the horizontal rotating of one of the jaws (30A, 30B) in relation to the other, thereby the gripping of the thread (22) is operable via the top (44A) of the rod (36) being disposed above the thread (22), thereby reducing occupied space (220) around the thread (22), required for the gripping.

    摘要： The present invention is a die positioning system for use in positioning mobile or fixed dies. The system includes a pair of key bars, a pair of key disc inserts, a set of key discs, and a set of disc backers. The key bars and key discs serve to offset manufacturing dies or die holders. Using key bars and/or key discs from different pairs of key bars and/or sets of key discs also allows for precise angulation of the dies or die holders. The key discs are held in place between the die and die holder, or between the die holder and key base, by the key disc inserts and angled (if feasible) by the disc backers. The key bars, located between the key disc inserts and the die or die holder allow additional offset of the die or die holder. The solid, stacked configuration of the key bars and key discs prevents the die or die holder from gradually or suddenly losing its positioning.

    摘要： A die for cutting screw-threads, especially for cutting threads into steel for reinforcing concrete and the like with an external thread cutting machine to which the die is operatively connectible by means of a mounting portion having a support surface is disclosed. The die includes a cutting portion having a plurality of cutting teeth arranged in a cutting plane and a guide portion adjacent said cutting portion, which guide portion has a plurality of teeth arranged in a guide plane. The length of the guide portion corresponds to about 3 to 6 times the length of the cutting portion and is approximately 10 to 20 times the length of the cutting plane.
