摘要： A combplate closes the terminal ends of a continuous belt transport system having grooved carrier plates. The combplate has a plurality of protrusions and a communications board. The plurality of spaced apart projections are located along the one lateral edge with a portion thereof extending forward of the one lateral edge, shaped to align with and pass between the carrier plate grooves, and provided with a detector that senses a break in its integrity and a circuit for communicating its status externally. The communications board is in electrical contact with each of the projections for repeatedly monitoring the status of each projection to detect a break in a projection's integrity.

摘要： A relatively inexpensive bushing easily installed extending through walls, particularly, gypsum board membrane walls for providing firestopping around a limited number of linear penetrating members such as cables or wires. This grommet construction includes first and second half sections for facilitating attachment around cables more easily. A split internal seal preferably of resilient foam material is positioned within a split mechanical shell which facilitates placing of the bushing around penetrating members prior to placement thereof through walls or after positioned thereof penetrating through a panel such as wallboard. A split mechanical shell with a two-piece foam insert retained within a bore extending therethrough can be formed as two separable half cylindrical shells. Barbs are included on the outer portion of the shell to facilitate mounting thereof. The foam firestopping seal portion can be intumescent.
摘要翻译： 一种相对便宜的衬套，其易于安装延伸穿过壁，特别是石膏板膜壁，用于围绕有限数量的线性穿透构件（例如电缆或电线）提供阻火。 该索环结构包括第一和第二半部分，以便于更容易地在电缆附近。 优选地由弹性泡沫材料分离的内部密封件定位在分裂机械壳体内，其有助于将套管围绕穿透构件放置在穿过构件之前，或者在其穿过壁穿过诸如墙板的面板定位之后。 具有保持在延伸穿过其中的孔内的两件式泡沫插入件的分体机械壳可以形成为两个可分离的半圆柱形壳。 倒钩被包括在外壳的外部部分以便于其安装。 泡沫阻火密封部分可以膨胀。
