    • An enhancement to a typical four-function calculator. With this enhanced calculator, lottery players may generate psuedo-random integer combinations for their use in selecting numbers on which to place their bets. The enhanced calculator allows users to select the type of lottery game for which the number combinations will be generated by specifying the quantity of numbers generated and the bounds of the range within which the numbers will be generated through two key strokes of dedicated keys. The first key stroke utilizes a key designated by the particular lottery game. The second key stroke utilizes a key designated by a popular range of numbers used by the various lotteries. This invention relieves the user from having to rely on his limited supply of "magical" dates, ages, social security numbers and so forth.
    • 增强典型的四功能计算器。 使用这种增强的计算器,彩票玩家可以生成伪随机整数组合,用于选择要投注的数字。 增强的计算器允许用户通过指定产生的数量的数量和通过专用键的两个关键行程产生数字的范围的范围来选择将产生数字组合的彩票游戏的类型。 第一个关键笔划使用特定彩票游戏指定的键。 第二个关键笔划使用由各种彩票使用的普遍数量的数字指定的键。 本发明缓解了用户不得不依靠他有限的“魔法”日期,年龄,社会保障号码等。

    • This invention relates to a computer numerical control (CNC) machine tool system having a novel terminal controller and system therefor to control a machine tool generally with at least two axes and more probably three, with stepping motor controls for point-to-point positioning of the machine tool to an almost infinite variety of steps (generally not more than 200). The novelty resides in the ease of programming directly on the terminal controller of the CNC machine tool system. Generally at least some editing and offsets will be programmed from the machine tool.The terminal controller consists of a microprocessor with some RAM and ROM, together with address and data bus plus I/O for magnetic tape handling and display for 6 to 8 digits in each of the X and Y positions, together with numeric keyboard for data input to the program steps and functional keys to control operation-automatic, manual and step-by-step, as well as controls for program input from tape to memory and memory to tape.Particular features include the ease of inputting a program and preparing a tape and then editing the tape while in operation. Further features include circular and linear interpolation. For circular interpolation there are no quadrant limitations and a full or partial circle may be cut.
    • 本发明涉及一种具有新颖的终端控制器及其系统的计算机数控(CNC)机床系统,该系统用于通常具有至少两个轴并且更可能三个控制机床,步进电机控制用于点对点定位 机床几乎无限多种步骤(一般不超过200台)。 新颖之处在于直接在CNC机床系统的终端控制器上进行编程。 通常至少有一些编辑和偏移将从机床编程。 终端控制器由具有一些RAM和ROM的微处理器,以及地址和数据总线以及用于磁带处理的I / O和在X和Y位置的每个位置显示6到8位数字,以及用于数据输入的数字键盘 程序步骤和功能键来控制操作 - 自动,手动和分步,以及从磁带到内存和内存到磁带的程序输入控制。 特殊功能包括输入程序和准备磁带,然后在运行时编辑磁带的方便。 其他功能包括圆形和线性插值。 对于圆弧插补,没有象限限制,可以切割全部或部分圆。
