    • The adjacent terminals of adjacent battery cells are grouped in regularly spaced pairs of contacts. A first commutating member has a plurality of regularly spaced contact members effective to connect the contacts of each pair but one and is movable sequentially through a plurality of positions to vary the unconnected contact pair. One of the contact members adjacent the unconnected contact pair provides a first output terminal. A second commutating member has a single contact member effective to connect the contacts of one of said pairs and provide a second output terminal and is movable sequentially through a plurality of positions to vary the connected contact pair. Actuator means are movable sequentially through a plurality of positions in a first direction and a second direction and are connected through a unidirectional clutch to the second commutating member to move it in one direction to increase the number of cells connected across the output terminals with movement of the actuator means in its first direction and through a unidirectional clutch to the first commutating member to move it in the same one direction to decrease the number of cells connected across the output terminals with movement of the actuator means in its second direction, thereby varying the output voltage in a stepped fashion and equalizing the discharge of the individual cells with such variation.
    • 相邻电池单元的相邻端子被组合成规则间隔的触点对。 第一换向构件具有多个规则间隔的接触构件,其有效地连接每对的触点,但是可以顺序地移动通过多个位置以改变未连接的触点对。 与未连接的触点对相邻的接触构件中的一个提供第一输出端子。 第二换向构件具有有效地连接所述对之一的触点的单个​​接触构件,并提供第二输出端子,并且可以顺序移动通过多个位置以改变所连接的触点对。 致动器装置可沿第一方向和第二方向顺序地移动通过多个位置,并且通过单向离合器连接到第二换向构件以沿一个方向移动,以增加跨过输出端子连接的单元的数量, 致动器在其第一方向上并且通过单向离合器连接到第一换向构件,以沿着相同的一个方向移动它,以通过致动器装置在其第二方向上的运动来减小连接在输出端上的单元的数量,从而改变 输出电压,并以这种变化均衡各个电池的放电。

    • An internal combustion engine having interconnected main and auxiliary combustion chambers, respectively, supplied with air-fuel mixtures through separate main and auxiliary intake passages is provided with an inlet valve having a single stem carrying two valve elements, one controlling each inlet port. At least one of the valve elements is resiliently positioned on the stem to permit relative movement between the elements and thus obtain positive seating of both valve elements on their respective valve seats. The arrangements permit actuation of the valve by conventional single valve actuating means.
    • 具有分别通过单独的主和辅助进气通道供应有空气 - 燃料混合物的主燃烧室和辅助燃烧室的内燃机设置有入口阀,其具有承载两个阀元件的单个阀杆,一个控制每个入口端口。 阀元件中的至少一个弹性地定位在杆上以允许元件之间的相对运动,从而获得两个阀元件在它们各自的阀座上的正向安置。 该布置允许通过传统的单阀致动装置致动阀。
