    摘要： The present invention provides a blind bolt fastener having a core bolt. The core bolt has a threaded portion and a non-threaded portion engaging a deformable sleeve and a body. A protrusion extends from the sleeve or the body to engage a groove in the core bolt to prevent axial movement of the core bolt with respect to the body and the sleeve. An optional drive nut is positioned between a head of the body and wrenching flats of the core bolt. The drive nut has protrusions engaging mating members in the head of the body.

    摘要： Disclosed is a latch assembly that includes an in-line fuse, which prevents damage to the latch assembly and its component parts in the event that a force in excess of a predetermined force is exerted on the latch handle. The latch assembly includes a latch housing and a latch, which is mounted in the latch housing. The latch includes a latch handle having a trigger assembly adapted to retain and release the handle from a locked position. The latch handle in turn causes an arm assembly to cause the movement of a push/pull type cable assembly. The in-line fuse is pivotally mounted to the arm assembly, and positioned in-line with the push/pull cable. The in-line fuse pin includes a sacrificial section that is designed to change in the event that excessive forces are applied to the latch handle. Thus, when a latch assembly operator exerts excessive force in an attempt to move the latch into the locked position, and corrosion or an obstruction are present to prevent the locking mechanism from locking the panel, the in-line fuse pin will fail, thereby preventing damage to the latch mechanism and cable assembly. Once the in-line fuse pin fails, the latch loses resistance, alerting the operator that a problem with the latch mechanism needs to be corrected.

    摘要： The paving system has a perforated pavement covering a deep substrate of mainly hard nodules or shells, the whole being surrounded by impervious walls to provide temporary storage in the interstices for chemical spillage or flood water, wherein liquids may be chemically treated or biologically decomposed, and from whence the rate of outflow may be regulated, the pavement consisting of preformed pavings of brick, concrete or other material, laid edge to edge without mortar or cement, and these pavings can be perforated or notched to allow liquids to run down into the substrate. The pavings are laid on a screen which filters out solid particles to reduce clogging. The system allows biological substances to grow, or be introduced, with or without additional nutrients, and allows chemical treatments to be introduced, from above, when needed. The whole pavement system can be lifted out for cleaning or, substitution, and relaid as new.

    摘要： Labels in sheet form are first separated into strips along spaced parallel perforation lines extending in the direction of sheet movement and then into individual labels along spaced perforation lines extending in a direction transverse to sheet movement. The strip separation step can be accomplished with one of three ways. The first embodiment includes a two driven pressure rollers one of which has a resilient exterior surface including discontinuous alternating larger and smaller diameter areas and the other has a rigid continuous surface of different diameter sections. The rollers cooperate to clamp the sheet at points between the perforation lines as it moves and exert to a force along the perforating lines to burst same. The second embodiment involves moving belts which clamp the sheets between the perforation lines as it moves, gradually separating into different planes. The third embodiment includes a reciprocating element with fins and a pressure pad with slots aligned with the perforation lines to accomodate the reciprocating fins. Transverse separation is accomplished by first and second spaced pairs of rollers. The second pair of rollers is rotated at a higher speed than the first pair such that the labels are completely separated. The individual labels can be accumulated on a slowly moving conveyor.

    摘要翻译： 片材形式的标签首先沿着沿片材移动方向延伸的间隔开的平行穿孔线分开成条，然后沿横向于片材移动的方向延伸的间隔开的穿孔线分成单独的标签。 条带分离步骤可以用三种方法之一完成。 第一实施例包括两个从动压力辊，其中一个具有弹性外表面，其包括不连续交替的较大和较小直径区域，另一个具有不同直径部分的刚性连续表面。 辊子协同作用，将片材夹紧在穿孔线之间的点处，并沿着穿孔线施加力以使其相同。 第二实施例涉及移动带，其在移动时将片夹紧在穿孔线之间，逐渐分离成不同的平面。 第三实施例包括具有翅片的往复运动元件和具有与穿孔线对准的狭槽的压力垫以容纳往复式翅片。 横向分离是通过第一和第二间隔的辊对实现的。 第二对辊以比第一对更高的速度旋转，使得标签完全分离。 单个标签可以积累在缓慢移动的输送机上。
