    摘要： A strap accumulator for use between strapping apparatus and apparatus for dispensing strap from the outside of a mill-wound supply reel, includes a coil holder for accommodating a ribbon-wound coil of dispensed strap. The outer diameter of the coil is constrained by an expandable spring steel hoop biased to a contracted condition. Motor-driven feed wheels feed strap from the supply reel through a gap in the hoop to the outside of the coil along the inner surface of the hoop. The coil is laterally retained by side structure having an aperture permitting withdrawal of strap from the center of the coil. The natural expansion of the coil holds the hoop expanded for opening a switch to deenergize the feed motor. Withdrawal of strap from the coil contracts it, allowing the hoop to contract for closing the switch and energizing the feed motor to feed more strap to the coil. Safety switch means are provided to deenergize the strapping apparatus in the event of malfunction of the accumulator. The accumulator may be free standing or commonly mounted with the strap dispensing apparatus.

    摘要翻译： 用于捆扎装置和用于从磨机供给卷轴的外部分配带的装置的带式蓄能器包括用于容纳分配带的带状卷绕线圈的线圈架。 线圈的外径受到偏压到收缩状态的可膨胀弹簧钢箍约束。 马达驱动的进给轮从供应卷轴通过箍的间隙沿着箍的内表面馈送到线圈的外部。 线圈由具有允许从线圈的中心抽出带的孔的侧面结构侧向保持。 线圈的自然膨胀保持用于打开开关的箍膨胀以使进给马达断电。 从线圈退出带子将其收起，从而允许箍收缩以关闭开关并为进给电机通电以将更多的带馈送到线圈。 提供了安全开关装置，用于在蓄能器发生故障的情况下使捆扎装置断电。 蓄能器可以是自由站立的或通常安装在带分配装置上。

    摘要： A seal structure between a circumferentially extending array of stator vanes and an outer case is disclosed. Various construction details that allow the seal structure to accommodate differences in axial and radial growth between the outer case and the vane array are developed. A continuous ring disposed between the vane array and the outer case cooperates with a first seal member to block leakage of working medium between the ring and the vane array. The continuous ring cooperates with a second seal member to block leakage of the working medium between the ring and the outer case.

    摘要： An impact printer is provided with an easy load print wheel mechanism. A print wheel cartridge, containing a print wheel therein, is inserted into a print wheel loaded position and removed therefrom without disturbing the position of a print wheel drive motor or ribbon cartridge. The print wheel drive motor shaft is automatically coupled to the print wheel within the cartridge upon insertion of the cartridge into print wheel loaded position.

    摘要： An article and a method for manufacturing the same, for use as a jaw face of a vise and which applies pressure evenly along any approximately flat surface clamped therein. The face comprises a plurality of cantilevered beams integral with the body of the jaw. The beams are spaced apart from each other and in the preferred embodiment have along a corresponding exterior surface of each, a pair of projections the tips of which are tangent to a geometrically flat plane. When the jaw is used, the projections bear against a flat surface of the workpiece to be clamped and the individual beams deflect slightly to correct for deviations from flatness in the flat surface, thereby assuring that the clamping force is distributed relatively evenly along the surface.
