Abstract: A sealing plug configured for sealing a passage of a curtain wall mullion. The passage has a maximum width and a length. The sealing plug includes a main body extending from a first surface to a second surface. The main body has a width at least as large as the passage maximum width and a length at least as large as the passage length. The main body is manufactured from a compressible foam. An intumescent layer is defined along at least one of the first and second surfaces.

Abstract: 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.

Abstract: A football comprising:a. an elongated football having four equally spaced seams extending the length of said football;b. lacings mounted on two of said seams located on opposite sides of said football to provide additional gripping surfaces on said football while maintaining perfect balance in said football, said lacings extending only along the central portion of said football.

Abstract: A tubular wire marker sleeve is disclosed. The sleeve includes a central portion which is flattened by ultrasonic welding to form a releasable bond and end extents which are unflattened facilitating insertion of an electrical wire into the sleeve. Plural sleeves may be assembled on a support card for printing on the sleeve with a conventional typewriter or computer printer.
