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： 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.
