    • A lateral connector assembly for connecting a bone engaging fastener to an elongated member, such as a spinal rod includes a lateral connector having an elongated opening for receiving a portion of the bone engaging fastener therethrough. The lateral connector includes a plate portion and an integral yoke portion, which yoke portion is attached to the elongated member by way of a clamp. The lateral connector assembly can include variable angle means between the clamp and the yoke portion of the lateral connector that permits rotation of the lateral connector about an axis projecting outward from the spinal rod. The plate portion and the yoke portion of the lateral connector are oriented at non-perpendicular angles, preferably an angle greater than 100 degrees. In a further embodiment the plate portion of the lateral connector is curved so that as the bone engaging fastener slides along the elongated opening, it assumes variable angular orientations relative to the lateral connector assembly and the elongated rod.
    • 用于将骨接合紧固件连接到诸如脊椎杆的细长构件的侧向连接器组件包括具有用于接收通过其中的骨接合紧固件的一部分的细长开口的侧向连接器。 横向连接器包括板部分和整体轭部分,该轭部分通过夹具附接到细长部件。 横向连接器组件可以包括位于夹持器和横向连接器的轭部之间的可变角度装置,其允许横向连接器围绕从脊柱杆向外突出的轴线旋转。 横向连接器的板部分和轭部被定向成非垂直的角度,优选地大于100度的角度。 在另一实施例中,横向连接器的板部分是弯曲的,使得当骨接合紧固件沿着细长开口滑动时,其相对于横向连接器组件和细长杆呈现可变的角度取向。

    • A portable accordion file organizer including rectangular front and back panels, accordion walls connecting opposite sides and the bottom of the front and back panels, and N sequential divider panels Pn secured to the accordion walls between the front and back panels. Each divider panel has a height greater than the height of the divider panel in front of it and less than the height of the divider panel behind it. The divider panels also each have a cutout section in its top edge wherein the cutout sections of adjacent divider panels are laterally spaced from one another on alternating sides of the center of the divider panel, and have a height which is substantially at least the difference in the height of adjacent divider panels.

    • A programmable electronic calculator for numerical evaluation of mathematical problems operates through the application of one or more basic mathematical operators, properly grouped, to each input numerical operand of a mathematical problem according to the accepted rules of mathematical combinations. One may select any numerical operand, any of the four basic arithmetic operators, left parenthesis and right parenthesis to denote groupings, a storage register for receiving a numerical operand to be used in computation or a numerical operand representing a result of a partial or final computation, or a storage register whose contents it is desired to print. Entry of each numerical operand and mathematical operator is accompanied by a printed record of that numerical operand and that mathematical operator so that the mathematical problem may be continually monitored as it is being entered. Depression of an equals key is followed by evaluation of previously designated operations and printing of the result. Selection of a left (or opening) parenthesis causes the contents of first and second accumulator registers in an arithmetic unit to shift to third and fourth accumulator registers in the arithmetic unit respectively. Selection of a right (or closing) parenthesis causes the shifting and combining of previously stored numerical operands to produce the result of the arithmetic combination embraced within a sequence denoted by a mating left parenthesis. One may select a learn mode in which steps are entered in a learn memory by working out a mathematical problem, each selected operation corresponding to a step in the learn memory. Thereafter, one may select an automatic computation mode to cause the operations previously stored in the learn memory to be carried out in sequence until a desired result is obtained or a predetermined point in the program stored in learn memory is reached.
    • 用于数学问题数值评估的可编程电子计算器通过根据公认的数学组合规则,将一个或多个基本数学运算符应用于数学问题的每个输入数值操作数,进行适当分组。 可以选择任何数值操作数,四个基本算术运算符,左括号和右括号中的任一个表示分组,用于接收要用于计算的数字操作数的存储寄存器或表示部分或最终计算结果的数值操作数 ,或其内容需要打印的存储寄存器。 每个数字操作数和数学运算符的输入都伴随着该数值操作数和数学运算符的打印记录,以便数学问题可以在输入时连续监视。 对等号键的抑制之后是先前指定的操作的评估和结果的打印。 选择左(或开)括号会使算术单元中的第一和第二累加器寄存器的内容分别转移到算术单元中的第三和第四累加器寄存器。 选择右(或关闭)括号会导致先前存储的数字操作数的移位和组合,以产生包含在由左对齐的左括号表示的序列中的算术组合的结果。 人们可以通过计算数学问题来选择学习模式,其中步骤被输入到学习存储器中,每个所选择的操作对应于学习存储器中的步骤。 此后,可以选择自动计算模式以使得先前存储在学习存储器中的操作按顺序执行,直到获得期望的结果或达到存储在学习存储器中的程序中的预定点。
