    • A method of fabricating a fuel assembly grid that includes providing a plurality of interconnected straps that form a lattice pattern, wherein the lattice pattern of the straps defines a plurality of cells, providing a sleeve that has a cylindrical portion and a flared portion, and inserting the sleeve into at least one of the cells. When inserted, at least a portion of the cylindrical portion of the sleeve will reside inside the cell and the flared portion will extend above the top end of the cell and overhang the perimeter of the cell. The flared portion is melted and flows over and fuses to the straps that define the cell. The straps may include weld tabs over which the melted material flows and to which it fuses. The melting and fusing steps also preferably cause any loose straps surrounding the cell to become attached to the sleeve.
    • 一种制造燃料组件网格的方法,包括提供形成格子图案的多个相互连接的带子,其中带子的格子图形限定多个单元,提供一个具有圆柱形部分和扩口部分的套筒,并插入 将套筒插入到至少一个单元中。 当插入时,套筒的圆柱形部分的至少一部分将位于电池内部,并且扩张部分将在电池的顶端上方延伸并且突出于电池的周边。 扩张部分熔化并流过并熔断到限定电池的带子。 带子可以包括焊接片,熔融材料在其上流动并熔化。 熔化和熔融步骤还优选地使围绕电池的任何松散的带缠绕到套筒上。

    • A method is provided for retrofitting an existing dead-bolt assembly with an electrically operated actuator (12, 112, 212, 312, 800). The electrically operated actuator automatically operates the dead-bolt assembly while preserving manual operation of the lock. The actuator assembly has rotating means for rotation of the drive bar (18), which in turn extends or retracts the bolt (14) of the lock. The rotating means may be a lever (28, 128, 238, 328, 438, 818) attached to the drive bar (18) that is pivotable about the axis of rotation of the drive bar (18). The actuator assembly has driving means that forces the rotating means to rotate. The driving means is responsive to an electrical signal, which, for example, may be initiated from a remote-controlled transmitter (502, 602). The driving means may include a motor (20, 120, 220) for rotating a rod (22, 122, 222, 322) that in turn operates an assembly that rotates or drives the rotating means. In response to an electrical signal, the driving means actuates the rotating means to affect either a locking or unlocking operation, which operations are always completed by placing the actuator assembly in a state whereby the bolt of the lock may subsequently be extended or retracted manually, or automatically by the driving means.
    • 提供了一种用于使用电动致动器(12,112,212,312,800)来改装现有的死栓组件的方法。 电动执行器在保持锁的手动操作的同时自动操作止螺栓组件。 致动器组件具有用于使驱动杆(18)旋转的旋转装置,其又使锁的螺栓(14)延伸或缩回。 旋转装置可以是连接到驱动杆(18)的杠杆(28,128,238,328,438,818),其可围绕驱动杆(18)的旋转轴线枢转。 致动器组件具有迫使旋转装置旋转的驱动装置。 驱动装置响应于例如可以从遥控发射器(502,602)启动的电信号。 驱动装置可以包括用于旋转杆(22,122,222,322)的马达(20,120,220),所述杆(22,122,222,322)又操作旋转或驱动旋转装置的组件。 响应于电信号,驱动装置致动旋转装置以影响锁定或解锁操作,这些操作总是通过将致动器组件放置在一个状态中来完成,由此可以手动地将锁的螺栓伸出或缩回, 或由驱动装置自动。
