摘要： A self-contained tensioner and tightener device for a threaded stud characterized in that an expandable hydraulic tensioning device is disposable between a locking nut and a foundation surface from which the stud projects, and the locking nut and the elements of the tensioning device when removed from the stud are necessarily displaced onto and retained by a take-up finger extending from the tensioning device coaxial with the stud, whereby the entire tensioning and tightening assembly is self-contained and none of its parts necessarily separate from the combination when the combination is removed from the stud.
摘要翻译：一种用于螺柱的独立式张紧器和紧固器装置，其特征在于，可膨胀液压张紧装置在锁定螺母和基座表面之间是一次性的，螺柱从该基座表面突出，并且锁定螺母和张紧装置的元件从螺栓必须移动并由从与螺栓同轴的张紧装置延伸的卷取指状物保持，由此整个张紧和紧固组件是独立的，并且当组合被移除时，其整个部分必须与组合分离从螺柱。

摘要： A reusable positive locking device having a nut threaded onto a bolt shank to a certain closure position wherein a locking element is screwed onto the bolt shank against the nut and a crown element cupped over the end of the bolt shank is screwed onto the bolt shank to engage the locking element and is then given an additional increment of turning so as to elastically deform biasing means between the crown element and its threaded engagement with the bolt shank, thus closing up play among the bolt shank and the locking element and the crown and the nut, the threaded connections between the locking element and the bolt shank and between the the crown element and the bolt shank being of a different direction, and the locking and crown elements being held together against relative rotation by releasable detent means.
摘要翻译：一种可重复使用的正锁定装置，其具有螺纹连接到螺栓柄上的螺母到一定的关闭位置，其中锁定元件被拧到螺栓柄上以抵靠螺母，并且在螺栓柄的端部上方的冠状元件被拧到螺栓柄上，接合锁定元件，然后给予额外的转动增量，以便在冠部元件与其与螺栓杆的螺纹接合之间弹性变形偏置装置，从而封闭螺栓柄和锁定元件和冠部之间的游隙，并且螺母，锁定元件和螺栓柄之间以及冠部元件和螺栓柄之间的螺纹连接处于不同的方向，并且锁定和冠部元件通过可释放的制动装置保持在一起而不被相对旋转。

摘要： Apparatus is disclosed for decontaminating a nuclear reactor pressure vessel. It comprises a buoyant annular frame which descends into the vessel as the water level within it is lowered. Spray nozzles move around the frame on trolleys in a reciprocating fashion and spray water under high pressure on the inner surface of the vessel wall, resulting in automatic washdown of the reactor vessel.

摘要： Apparatus is disclosed for decontaminating the wall of a boiling water reactor cavity. A chassis on wheels is rollable on the refueling floor along the cavity curb. A pair of horizontal wheels roll against the curb. A support member extends upwardly and laterally from the chassis to clear the personnel handrail. A mast depends from the support member into the cavity and includes a horizontal reaction wheel bearing against the cavity wall. A vertically positionable carriage is mounted on the mast and carries water spray nozzles directed against the wall.
