  • Patent number: 10350670
    Abstract: The die forming process includes first passing a circular coarse thread cutter over the forming surface of the die at an angle away from parallel to a side edge matching a pitch for coarse threads to be formed by the die. The coarse thread cutter is truncated with a notch within a flattened tip, the notch forming upper portions of crests in the forming surface of the die. A fine thread cutter of circular form is then utilized to cut portions of the root of the dual threaded die. The fine thread cutter is angled relative to side edges of the die at an angle substantially half of an angle at which the coarse thread cutter is angled. The fine thread cutter cuts at a variable depth as the fine thread cutter advances along the root between the crests to form flanks of a bridge within the root.

    Abstract: A fatigue-resistant Nitinol instrument has a working portion in the deformed monoclinic martensitic state and an austenite finish temperature in the range of 40° to 60° C. Because the operating environment of the instrument is about 37° C., the working portion remains in the monoclinic martensitic state during its use. The relatively high austenite finish temperature and fatigue resistance is achieved by subjecting the nickel-titanium alloy to a final thermal heat treat in a temperature range of about 410° to 440° C. while the nickel-titanium alloy is under constant strain of about 3 to 15 kg. Further, the high austenite finish temperature is achieved without subjecting the alloy to thermal cycling to produce shape memory. Additionally, there are no intermediate processing steps occurring between obtaining a finished diameter of the wire or blank through cold working and the final thermal heat treat under constant strain.

    Abstract: Combination of a dental implant and an insertion tool for inserting the dental implant into a bone of a patient. The dental implant includes an anti-rotation means having a non-circular cross-sectional contour with at least one planar force transmission surface in the form of an anti-rotation surface (7a, 7b, 7c, 7d). The insertion tool includes an anti-rotation means having a non-circular cross-sectional contour with at least one planar force transmission surface in the form of a torque transmission surface (11a?, 11a?; 11b?, 11b?; 11c?, 11c?; 11d?, 11d?). One of the anti-rotation means forms a recess (6), and the other forms a bolt (10) having a rotational axis and designed to be received in the direction of the rotational axis in the recess (6), such that the at least one anti-rotation surface and at least one torque transmission surface can cooperate to transmit torque between the parts.

    Abstract: A cutting element for use in a cutting operation, comprising a cutting edge (CE) capable of cutting out material from a workpiece during the operation, to form therein a workpiece corner of angle alpha. There exists at least one view of the cutting edge in which a portion of the cutting edge is delimitable by a first (L1) and a second (L2) line oriented tangentially to the portion of the cutting edge portion at respective tangency points A and B. The lines form therebetween a cutting angle corresponding to the workpiece corner angle alpha and have a vertex 0. For a bisector of the cutting angle intersecting the portion of the cutting edge at the point C, the projection C of the point C of the portion of the cutting edge on a line OL passing through the vertex 0 perpendicularly to the plane of the one view is located between projections A1 and B? of the respective points A and B of the portion of the cutting edge on the line OL.
