    • An anchor bolt is provided which includes a head, a drill portion, and an intermediate shank portion. The intermediate shank portion has a longitudinal cavity formed therein for receiving a mounting set screw. An external thread is formed on the shank portion for threading the anchor bolt into the wall. The shank portion is divided by a slit into at least one portion and the external thread on the shank portion is divided into a plurality of discrete thread segments by the slit. The drill portion has a cutting edge and at least one flute formed therein which also extends to a drill tip and to a sharpened point. The anchor bolt is driven into the wall portion with a screwdriver, and then a mounting set screw is inserted into the longitudinal cavity. When the mounting set screw is inserted into the cavity, the set screw causes a portion of the shank portion to separate from the shank portion to engage with the wall.
    • 提供了一种锚定螺栓,其包括头部,钻头部分和中间柄部分。 中间柄部具有形成在其中的纵向腔,用于接纳安装固定螺钉。 在柄部上形成外螺纹,用于将锚定螺栓穿入壁中。 柄部分被狭缝分成至少一部分,并且柄部分上的外螺纹通过狭缝分成多个离散螺纹段。 钻头部分具有切削刃,并且其中形成有至少一个凹槽,其还延伸到钻头尖端和锋利点。 用螺丝刀将地脚螺栓推入壁部,然后将一个固定螺钉插入到纵向腔中。 当安装定位螺钉插入空腔中时,固定螺钉使得柄部分的一部分与柄部分分离以与壁接合。

    • A floor sweep auger system for mounting in an existing grain bin of the type having a wood or concrete floor and a cylindrical wall. A stationary auger is mounted with an inner intake end secured to the floor at the center of the bin and an outer discharge end extending through the wall of the bin at a location above the floor. A moveable auger, which has a length substantially equal to the radius of the bin, is mounted for sweeping an arc of approximately 360.degree.. A center mounting coupling of the moveable auger, which has a fixed pivot axis and a moveable pivot axis, allows the moveable auger to start from a position parallel to and adjacent one side of the stationary auger and to swing through the arc to a terminal position parallel to and adjacent the opposite side of the stationary auger. The system is particularly designed for use in existing grain bins without requiring any modification to the floor and yet will allow a pick-up of substantially all of the grain in the bin without any manual movement of the grain.
    • 一种用于安装在具有木材或混凝土地板和圆柱形壁的类型的现有粮仓中的落地螺旋钻系统。 固定螺旋钻安装有内部入口端,其固定在箱的中心处的地板上,并且外部排出端在地板上方的位置延伸穿过箱的壁。 安装有可移动的螺旋推运器,其长度基本上等于料仓的半径,用于扫掠大约360度的弧度。 具有固定枢转轴线和可移动枢转轴线的可移动螺旋钻的中心安装联接件允许可移动螺旋钻从平行于和邻近固定螺旋钻的一侧的位置开始并且通过弧线摆动到终端位置 平行于并邻近固定螺旋钻的相对侧。 该系统特别设计用于现有的粮食仓,而不需要对地板进行任何修改,而且将允许在箱中拾取几乎所有的谷物,而不会任何手动移动谷物。

    • Apparatus for counting a number of sheet-like articles such as corrugated sheets of paper is disclosed as comprising a platen mounted to be driven rectilinearly from a topmost position to engage the top of the stack, a motor for reversibly driving the platen and a counter for counting the number of pulses required to drive the platen from its topmost position to the top of the stack, thus providing an indication by the number of counted pulses of the distance between the topmost platen position and the top of the stack. Further, a circuit is provided for determining the difference between the first measured distance and the total distance between the bottom of the stack to thereby provide an indication of the stack height, which stack height in a particular unit of measurement, e.g., inches, is multiplied by a factor corresponding to the number of sheets per unit measurement to provide the number of sheets in the stack.
    • 公开了用于计数多个片状制品如波纹纸的装置,包括安装成从顶部位置直线驱动以接合堆叠顶部的压板,用于可逆地驱动压板的电动机和用于 计算将压板从其最高位置驱动到堆叠顶部所需的脉冲数,从而通过最上面的压板位置和堆顶部之间的距离的计数脉冲数来提供指示。 此外,提供了一种用于确定第一测量距离和堆叠底部之间的总距离之间的差异的电路,从而提供堆高度的指示,其中特定测量单位(例如,英寸)中的堆叠高度为 乘以与每单位测量的纸张数相对应的因子,以提供堆叠中的纸张数量。
