    • An expansion joint system which is provided to accommodate forces applied to highway construction during normal changes in ambient conditions, and which is also designed to withstand seismic forces and vehicular forces, which may be applied in transverse and longitudinal directions. The system includes spaced-apart transverse vehicle load bearing members which are placed in a gap defined between adjacent sections of highway construction, longitudinally extending support members positioned beneath the load bearing members, means embedded within the adjacent roadway sections that control longitudinal, transverse and vertical movement, and a mechanism for controlling the spacing between the transverse load bearing beams. Preferably, this mechanism maintains a substantially equal distance between the transverse load bearing beam members.
    • 一种膨胀接头系统,用于在环境条件正常变化期间适应施加于公路施工的力,并且还被设计成承受横向和纵向方向施加的地震力和车辆力。 该系统包括间隔开的横向车辆承载构件,其被布置在限定在高速公路结构的相邻部分之间的间隙中,位于承载构件下方的纵向延伸的支撑构件,嵌入相邻道路段内的装置,其控制纵向,横向和垂直 运动和用于控制横向承载梁之间的间隔的机构。 优选地,该机构在横向承载梁构件之间保持基本相等的距离。

    • Fiberglass filament waste is cut into segments with an apparatus comprised of a feeder that includes a cutting roller having a rotatable shaft with a plurality of spaced circular cutting blades mounted thereon, and a waste feeder having a discharge opening adjacent said roller for conveying said waste into engagement with the periphery of the blades, the feeder including at first and second spaced surfaces extending from a waste inlet opening to a waste discharge opening, at least one of the surfaces being pivotal adjacent the waste inlet opening to expand the discharge opening under pressure from waste being conveyed between the surfaces. At least one of the surfaces, which may be a surface of a conveyor belt, is moveable toward the discharge opening, while the other surface may be stationary, or move toward the discharge opening. In one embodiment, the lower surface moves toward the discharge opening, while the upper surface moves away from the discharge opening to equalize the volume of waste being fed. A slotted stationary plate supports the waste during cutting.
    • 玻璃纤维细丝废料被切割成具有包括进料器的设备的设备,该设备包括具有安装在其上的多个间隔开的圆形切割刀片的可旋转轴的切割辊,以及与所述辊子相邻的排出口,用于将废物输送到 与叶片的周边接合,所述进料器包括从废物入口开口延伸到废物排放口的第一和第二隔开表面,至少一个表面在废物入口开口附近枢转,以在压力下膨胀排出口 废物在表面之间传送。 可以是输送带表面的表面中的至少一个能够朝向排出口移动,而另一个表面可以是静止的,或者朝向排出口移动。 在一个实施例中,下表面朝向排出口移动,同时上表面远离排放口移动以均衡所供给的废物的体积。 开槽固定板在切割过程中支撑废物。
