    • Projectile ramming apparatus includes a rammer pawl for engaging the base of a projectile with a rigidizable chain attached to the rammer pawl for providing reciprocating movement thereto. The rigidizable chaining includes a plurality of rows of links having adjacent links pivotally attached to one another. A perimeter of each link enables fixed engagement of adjacent links on each row upon coordinated pivoting of adjacent links in each row and, further, for enabling release of the fixed engagement upon reverse coordinated pivoting of adjacent links. A drive is provided for reciprocally moving the chain and for pivoting adjacent links in order to rigidize the chain as the chain is moved in a forward direction; and unlocking, or unrigidizing, adjacent links as the chain is moved in a reverse direction. The chain is moved at a generally constant velocity enabled by the link perimeter.
    • 射弹捣打装置包括一个夯锤,用于将射弹的底部与可连接到夯锤上的可固定的链条相接合,以提供往复运动。 可固定的链接包括具有彼此枢转地连接的相邻链节的多排连杆。 每个链节的周边使得能够在每排中的相邻链节的协调枢转时在每行上的相邻链节的固定接合,并且还用于在相邻链节的反向协调枢转时实现固定接合的释放。 提供驱动器,用于往复移动链条并用于枢转相邻连杆件,以便当链条向前移动时使链条刚性化; 并且当链条沿相反的方向移动时,相邻的链节解锁或解链。 链条以通过链接周边使能的通常恒定的速度移动。

    • A flip-flop circuit includes a differential stage coupled to a transparent latch. Respective sides of the differential stage, referred to as the “output side” and the “reference side,” are precharged high during a precharge phase. During an evaluation phase, the state of a data input signal is sensed. Depending upon the state of the data input signal, either the output side or the reference side is discharged. Also, during the evaluation phase, the transparent latch is enabled, and thereby samples and stores an output signal from the output side of the differential stage. Upon initiation of the next precharge phase, the transparent latch is quickly disabled (i.e., is placed in an opaque state), and retains its present state. Since only a single side of the differential stage is used to drive the transparent latch, the differential stage may advantageously be implemented in an asymmetric fashion. In yet an additional embodiment, complex logic may be added to the differential stage of the flip-flop circuit.
    • 触发器电路包括耦合到透明锁存器的差分级。 被称为“输出侧”和“参考侧”的差分级的各个侧在预充电阶段被预充电为高电平。 在评估阶段,检测数据输入信号的状态。 根据数据输入信号的状态,输出侧或参考侧都被放电。 此外,在评估阶段期间,透明锁存器被使能,从而采样并存储来自差分级的输出侧的输出信号。 在下一个预充电阶段开始时,透明锁存器被快速禁用(即,处于不透明状态)并保持其当前状态。 由于仅使用差分级的单侧来驱动透明锁存器,差动级可有利地以非对称方式实现。 在又一个实施例中,复合逻辑可以被添加到触发器电路的差分级。
