    • A calculator of flat design with a surface chart showing marginal scales and diagonal inner ones. The top of the calculator serves as a cover attached marginally to a case underneath. Also, the top has a diagonal slot, and is surmounted by a flat pointer which has a similar slot, and can be slid and rotated to relate to numerical values in the scales. An axial post is installed to pass through and be movable to any desired point in the slots, with means disengaging the post by finger pressure for movement away from said point.
    • 平面设计的计算器,具有显示边缘尺度和对角线内部曲面的曲面图。 计算器的顶部作为一个封面,附加在下面的情况下。 此外,顶部具有对角槽,并且被具有类似狭槽的平坦指针所覆盖,并且可以滑动并旋转以与秤中的数值相关。 安装轴向柱以通过并且可移动到槽中的任何所需点,其中手段通过手指压力离开柱以便远离所述点移动。

    • A personal portfolio computer having a primary utility as a record keeping and stock value calculating device is generally constructed in the form of an envelope with rectangularly shaped substantially flat sides being interconnected along the opposite longer parallel edges. In the assembled form, the two flat sides with transparent portions therein, is a pocket size envelope with a substantially flat slide located between the two sides and having a scale thereon so that it is visible through one of the transparent sides. The adjacent transparent side has a corresponding scale located thereon so that the slide may be manipulated for slide rule type calculations. The opposite side of the envelope structure has a record keeping means located between the two sides with the record keeping portion visibly apparent through the opposite transparent side, and with a portion of the record keeping means extending exteriorly of the transparent sides so that current data computed by the slide rule type structure may be recorded thereon. That portion of the permanent data on said record keeping means between said sides is protected by the presence of the transparent side.
    • 具有作为记录保存和库存价值计算装置的主要用途的个人投资组合计算机通常以具有矩形基本上平坦的边的信封的形式构造,沿着相对较长的平行边缘互连。 在组装形式中,其中具有透明部分的两个平坦侧面是具有基本平坦的滑动件的口袋尺寸的封套,位于两侧之间并且具有其上的刻度,使得其可透过透明侧之一可见。 相邻的透明侧具有位于其上的对应的刻度,使得可以对滑块进行滑动规则类型计算。 信封结构的相对侧具有位于两侧之间的记录保持装置,其中记录保持部分通过相对的透明侧可见,并且记录保持装置的一部分在透明侧的外部延伸,以便计算当前数据 通过滑动规则类型结构可以被记录在其上。 在所述侧面之间的所述记录保存装置上的永久数据的该部分由透明面的存在来保护。
