    • A power generator circuit is adapted to be driven by the output of a vehicle alternator (10). The circuit includes an input (22) for receiving a rectified DC output from the alternator, and a pair of step-up transformers (TFR1, TFR2) which are connected to the AC output from the alternator. Rectifiers are connected to the outputs of the step-up transformers, and are connected in series with the rectified DC output from the alternator to provide a relatively high voltage DC output. This output can be used to operate power tools, for example. The circuit includes a welding output (18, 20), and allows normal charging of the vehicle battery (32) when not being used as a power source.
    • 发电机电路适于由车辆交流发电机(10)的输出驱动。 电路包括用于接收来自交流发电机的整流DC输出的输入端(22)和连接到交流发电机的AC输出的一对升压变压器(TFR1,TFR2)。 整流器连接到升压变压器的输出,并与交流发电机的整流直流输出串联,提供相对高压的直流输出。 例如,该输出可用于操作电动工具。 电路包括焊接输出(18,20),并且当不用作电源时允许车辆电池(32)正常充电。

    • In order to reduce the flow resistance of a coolant flowing through a passage (63) in the support plate (64) of a boiling water reactor and entering the transition piece (50) at the lower end of a fuel assembly resting on said support plate (64), the lower rim (60) of the transition piece (50) forms a conically tapered surface which fits into a corresponding conical counter-surface (62) at the upper edge of said passage (63). The lower rim (60) of the transition piece (50) forms a circular inlet which is concentric with the passage (63) and has a size equal or slightly larger than the passage opening. Fingers (70) protruding laterally into said opening and extending down into said passage (63) are used to center the low rim (60) within the passage (63). Additionally, the end caps (90) of the fuel rods may be stream-lined and the lower tie plate (53) of the fuel assembly may be spaced apart from the inner surface of a fuel channel (52) by a plurality of ribs (86) which form a plurality of peripheral through holes (86') on each of the four inner surfaces (84) of the rectangular fuel channel (52).
    • 为了降低流过沸水反应堆的支撑板(64)中的通道(63)的冷却剂的流动阻力,并进入位于所述支撑板上的燃料组件的下端的过渡件(50) (64)中,过渡件(50)的下边缘(60)形成锥形锥形表面,该锥形表面装配在所述通道(63)的上边缘处的对应锥形对置表面(62)中。 过渡件(50)的下边缘(60)形成与通道(63)同心的圆形入口,其尺寸等于或稍大于通道开口。 用于将侧边突出到所述开口并向下延伸到所述通道(63)中的手指70将所述低边缘(60)定位在所述通道(63)内。 另外,燃料棒的端盖(90)可以是流线型的,并且燃料组件的下连接板(53)可以通过多个肋(...)与燃料通道(52)的内表面间隔开 86),其在矩形燃料通道(52)的四个内表面(84)中的每一个上形成多个周边通孔(86')。
