    • A set of shelving units which can be interlockingly mated together. Each shelving unit has a set of end panels is provided with substantially identical dimensions. At least one elongated cross member is joined to an edge of the end panels so that the end panels are spaced apart along the length of the cross member. At least two elongated cross members are joined to an opposite edge of the end panels. The two cross members are parallel and spaced apart to form a gap for receiving a cross member of a second shelving unit similarly constructed so that the shelving units can be interlockingly mated. The cross members of each shelf form a shelving surface.
    • 一套可以互锁配合的搁架单元。 每个搁架单元具有一组端面板,其具有基本相同的尺寸。 至少一个细长的横向构件连接到端板的边缘,使得端板沿着横梁的长度间隔开。 至少两个细长的横向构件连接到端板的相对边缘。 两个横向构件平行并间隔开以形成用于接收类似构造的第二搁架单元的横梁的间隙,使得搁架单元可互锁地配合。 每个搁板的横梁形成一个搁板表面。

    • A chip placement system of modular construction is provided for simultaneous population of circuit boards with component chips. A plurality of chip placement modules are provided, each having a conveyor means for receiving a planar from an adjacent one of the modules and transporting it through the module to a next adjacent one of the modules. Each module further includes a further plurality of chip placement subassemblies for simultaneously placing a respective plurality of chips in a preselected geometric pattern on the planar and a load plate which is slidably removable from the module which carries a plurality of stacks of chips disposed in the desired geometric pattern. The load plate of each module is periodically withdrawn in at least one of the stacks are substantially depleted, whereby a next load plate with a replenished supply of chips is slid into place. By arrangement of the conveyor system for lateral movement of the planars through each module, a plurality of such modules may be arranged side by side so as to form an assembly line, each module depositing a different geometric pattern of chips simultaneously before the planar is thence conveyed to an adjacent module. The system is reconfigurable to effect different chip placement patterns by sliding replacement subassemblies into each module or sliding additional or replacement modules into place along the line. Slideable load plate design provides for rapid replenishment of depleted chip supplies while minimizing assembly line down time.

    • A cartridge for housing a daisy wheel print element during printing use and non-use. The cartridge has a front, sides, and a back, and is structured to substantially enclose the print element. Included in the makeup of the cartridge are (1) a slot in the top of the front for accommodating a print hammer during printing operations, (2) an orientation opening generally centralized within the front to accept a matching orientation protrusion carried by the print element, (3) a loading opening in the bottom for insertion and removal of the print element, (4) a card holder carried by the top of the back, (5) a ribbon guide carried by the top of the front, and (6) a center bowed leaf spring located within the cartridge. The lower end of the spring acts against the lower inside of the back and the bow acts against the inside of the front adjacent the orientation opening. As such, a ramp is provided for caming the orientation protrusion toward the orientation opening during insertion of the print element into the cartridge. Upon engagement of the orientation opening and orientation protrusion, the spring then serves to maintain the print element latched in a desired rotational position.
    • 用于在打印使用和不使用期间容纳菊花轮印刷元件的盒。 盒具有前侧,后侧和后面,并且构造成基本上包围印刷元件。 包括在盒的构成中的是(1)在打印操作期间用于容纳打印锤的前部的顶部的槽,(2)通常集中在前部中的定向开口,以接受由打印元件承载的匹配的定向突起 ,(3)用于插入和取出打印元件的底部中的装载开口,(4)由背面顶部承载的卡夹,(5)由前部的顶部承载的色带引导件和(6 )位于墨盒内的中心弯曲的弹簧片。 弹簧的下端作用在靠背的下部内侧,并且弓与邻近定向开口的作用抵靠在前部的内侧。 因此,提供了一种斜面,用于在将打印元件插入盒中期间朝向定向开口凸轮定向突出部。 在接合定向开口​​和定向突起时,弹簧用于将打印元件保持在期望的旋转位置。
