| 21 | Wind Turbine Installation Comprising an Apparatus for Protection of Anchor Bolts and Method of Installation. | US13109927 | 2011-05-17 | US20120124924A1 | 2012-05-24 | Norman L. Tooman |
| A wind turbine installation comprises anchor bolts having a sheath or sleeve which extends above the cement foundation and the overlying grout layer. If desired, the sleeve may partially extend inside the base flange of the wind turbine tower. The sleeve may be manufactured from polypropylene, polyethylene or other materials having satisfactory mechanical properties, primarily that the material be capable of withstanding sufficient plastic deformation to cause the material to conform to the shape of the threads of the anchor bolts without the material failing. This swaging operation results in a crimped end which forms an interference fit with the threads of the anchor bolt thereby preventing or limiting the intrusion of water or other liquids into the bolt-sleeve annulus during the installation of the turbine foundation. | ||||||

| 23 | Precise columnar member and method of producing the same | US10129396 | 2002-05-06 | US20020162372A1 | 2002-11-07 | Junzo Ozawa; Kazutaka Aoyama; Takashi Asakura; Katsuaki Yokoi |
| The present invention relates to a metallic, precise columnar member having an outer diameter with high accuracy, wherein the columnar member comprises a plurality of flattened thread ridges having a predetermined outer diameter provided on the surface of a metallic columnar blank in an axial direction. The method of the present invention comprises the steps of using rolling to form a plurality of thread ridges on the surface thereof and using rolling or drawing to make the tops of the thread ridges flat. | ||||||
| 24 | Method of making threaded fasteners | US375145 | 1989-06-30 | US4941337A | 1990-07-17 | Ralph S. Emery |
| A threaded fastener is made by a method which involves forming a portion having an external thread form and a shank portion. The shank portion has at least one substantially circumferential groove the depth of which is such that the effective stress area thereby produced is less than the minimum effective stress area of the external thread form and is also such that yield of the threaded fastener occurs in use in the region of the or each groove at a predetermined load. The depth of the or each groove may be such that the diameter of the shank portion at the base of the or each groove is in accordance with the relationship: ##EQU1## where D is the diameter at the base of the or each groove (m).delta. is the tensile strength of the wire (N/m.sup.2)F is the load (N) required to produce yielding of the fastener in the region of the or each grooveK is a constant which is a function of the stress concentration factor appropriate to the shape of the groove and the type and composition of the material used to make the wire. | ||||||

| 26 | Method of an apparatus for semi-hot forming of metallic workpieces in a rolling operation | US3686911D | 1970-05-14 | US3686911A | 1972-08-29 | PLAGEMANN JURGEN; CONRAD HORST |
| In a semi-hot forming operation, a workpiece is supported between two tool rollers which are rotated in the same direction. During the rotational cycle of the rollers the workpiece is first electrically preheated to a desired temperature after which the forming operation takes place. The contact pressure between the rollers and the workpiece is relatively low during the preheating operation and is increased when the roll forming takes place. To heat the workpieces effectively, the rotational speed of the roller can be varied to preheat at a regulatable reduced speed and then to form the workpiece at an increased rate of speed. The circumferential surfaces of the rollers are segmented with a smooth portion and a profile portion, with the preheating taking place when the smooth part of the rollers are in contact with the workpiece and the forming taking place when the profile portion is in contact with the workpiece.
