    摘要： There is disclosed an easily releaseable, internally threaded fastener having at least one axial slot which extends substantially through the wall of the fastener. The external wall of the fastener is non-cylindrical, e.g. hexagonal, or three-lobed, to permit the application of a fastening torque to the fastener. The fastener is surrounded by a retainer sleeve having a mating, internal wall portion which provides hoop strength to the fastener. The retainer also has an annular recess in its internal wall whereby the retainer can be slid axially, or rotated, to release the fastener. The fastener assembly includes a metal spacer seated in each axial slot of the fastener to permit the even transmission of the fastener application torque. In preferred embodiments, the fastener is formed by cutting several axial slots through the body of the fastener, but terminating short of severing the threads, thereby providing a fastener which, when released by the retainer, will yieldingly fail, thus avoiding the mechanical shock of release which is experienced upon the release of separate fastener segments.

    摘要翻译： 公开了一种容易释放的内螺纹紧固件，其具有基本上延伸穿过紧固件的壁的至少一个轴向槽。 紧固件的外壁是非圆柱形的，例如， 六角形或三裂片，以允许将紧固扭矩施加到紧固件。 紧固件由具有匹配的内壁部分的保持器套筒围绕，该内壁部分为紧固件提供环箍强度。 保持器在其内壁中还具有环形凹部，由此保持器可以轴向滑动或旋转以释放紧固件。 紧固件组件包括安置在紧固件的每个轴向槽中的金属隔离件，以允许紧固件施加扭矩的均匀传递。 在优选实施例中，紧固件通过切割穿过紧固件主体的多个轴向狭槽而形成，但是终止于不能切断螺纹，从而提供紧固件，当紧固件释放时，紧固件将会屈服地失效，从而避免了机械冲击 在释放单独的紧固件段时经历的释放。

    摘要： An assembly for attaching a re-entry vehicle to its booster with a high preload force includes a split nut and a split band for encompassing the nut and retaining it in a collapsed condition in which it forces the booster against the re-entry vehicle at the desired preload level. The split band is held in an assembled condition about the nut by a plurality of separation bolts and a plurality of yieldable belleville washer and bolt assemblies. Actuating the separation bolts allows the band to move to a disassembled condition and the split nut to an expanded condition. However, the rate of their movements is controlled by the spring rate of the belleville washers whereby the preload is released in a gradual manner.

    摘要： Plastic pad at center of concave bevel of each semicircular segment maintains lateral and axial alignment when segments spread apart by pipe. In another special configuration, inside and outside segments are offset semicircles, with a greater dimension across opposed edges when abutting than middle. Inside threads of segments relieved at edges, with full threads at center and progressive decrease to each edge. Segments have cone portions opposite bevel, for engagement with concave seat of housing to tighten threads. Ring rotatable relative to housing but axially fixed has convex cone spaced from seat and engaged by bevel of segments for spreading. Resilient ring in peripheral groove of segments. Outside notches at segment edges receive housing pin or ring, to prevent relative rotation and restrain lateral play at abutting edges. Numerous variations of construction disclosed.

    摘要： A quick-release fastener device for fitment to the shank of a screw, stud or pin or the like device. The fastener is characterized by the provision of a collet member, which is composed of a number of segmental collet elements, and a retaining member which surrounds the collet member to retain the elements thereof in a cooperative relationship. The collet member is displaceable within or from the retaining member to permit separation of the collet elements one from the other and, hence, to permit quick release of the fastener from a device to which it is fitted.

    摘要： 1,122,696. Machining composite workpieces. G. C. MEIBUHR. 19 Aug., 1966 [25 Aug., 1965], No. 37331/66. Heading B3T. [Also in Division F2] A method of making a screw-thread insert comprises the steps of cutting a cylindrical metal tube in an axial direction to form first and second semi-circular metal pieces, holding these pieces together in a chuck with their cut portions abutting along a line 72, machining the outside and inside diameters to a circular condition, with tools 77 and 78, and, if required, forming inside and outside chamfers at the exposed end of the composite member with tools 79 and 80, producing a continuous screw-thread on the outside surfaces, which screw-thread is thus matched at the abutting cut portions, holding together the two matched threaded members 74 and 75 by means of a nut 82 threadedly engaging the newly cut thread, and cutting off an axial length of the threaded arcuate metal pieces by means of a tool 83.
