    • Parallel connected power supplies having parallel connected control
circuits which equalize output currents to a load even after one supply
is turned off

    • A power supply system comprises several power supplies, each of which has output terminals that are coupled in parallel to supply respective DC output currents at the same time to a single load. Each power supply also has a branch of a control circuit, and each branch from every supply is coupled in parallel to thereby form a complete control circuit. In these branches, control currents flow that cause the respective output currents from the several power supplies to equalize. Each power supply also has a circuit for automatically turning the supply off independent of the other power supplies when a component in the supply fails; and under such conditions, a switch in the control circuit branch of the failing supply automatically opens which prevents control current from flowing therein and enables the remaining supplies to share the added load.
    • 电源系统包括多个电源,每个电源具有并联耦合的输出端子,以将相同的DC输出电流同时提供给单个负载。 每个电源还具有控制电路的分支,并且每个电源的每个分支并联耦合,从而形成完整的控制电路。 在这些分支中,控制电流流动,导致来自多个电源的相应输出电流相等。 每个电源还具有一个电路,用于当电源中的一个组件发生故障时,独立于其他电源自动关闭电源; 并且在这种条件下,故障供电的控制电路分支中的开关自动打开,这防止控制电流流入其中,并使剩余的电源能够共享加载的负载。

    • Graphical information, such as a structural chemical formulae, composed of nodes and links between the nodes, or in a chemical formula ring positions and bonds, are coded by means of logic circuits responsive to actuation of a keyboard. The graphical data coded in binary digit form are stored, while contents of the store are scanned, decoded and applied in analog form to a display device. When recorded on a suitable medium they are made machine readable, for searching or similar processing. A luminous cursor indicates on the display the part of a structural formula that is subject to the next keyboard action. The store is organized about fixed display locations available as nodes. Alphanumeric characters identify atoms at nodes. Single, double or triple bonds in any of eight directions from a node towards another node may be registered and displayed. A cursor address register, a store address register and a comparator are used. Registering at one node a bond designated by character and direction transfers the cursor to the node at the other end of the designated bond. Other transfers of the cursor may be effected by the space bar with the use of the appropriate directional keyed instruction.
    • 由节点和节点之间的链接组成的结构化学式,或化学式环中的位置和键合的图形信息通过响应于键盘致动的逻辑电路进行编码。 存储以二进制数字形式编码的图形数据,同时存储器的内容以模拟形式被扫描,解码和应用于显示装置。 当在合适的介质上记录时,它们被制成机器可读的,用于搜索或类似的处理。 发光光标在显示屏上指示受下一个键盘操作的结构公式的部分。 该商店是关于可用作节点的固定显示位置的组织。 字母数字字符识别节点处的原子。 可以登记并显示从节点到另一节点的八个方向中的任一个中的单,双或三键。 使用光标地址寄存器,存储地址寄存器和比较器。 在一个节点上注册由字符和方向指定的键将光标移动到指定键的另一端的节点。 光标的其他传输可以通过使用适当的方向键控指令的空格键来实现。
