Abstract: A portable surge protection adapter includes a housing having first and second exterior faces. At least one electrical outlet is mounted in the housing. The outlet has apertures on the first exterior face which are oriented to receive the prongs of a standard electrical plug. An electrical plug mounted in the housing has at least two electrical prongs extending from the second exterior face. The prongs are prongs adapted to deliver electricity to the electrical outlet. A conditioning circuit mounted in the housing is electrically connected between the plug and the outlet. A prong cover pivots between a first position at which the prong cover encloses the prongs and a second position at which the prongs are exposed and insertable into a powered outlet. Data input and output ports are mounted in an exterior face of the prong cover. A data conditioning circuit is connected between the data input and output ports and is mounted in the prong cover.

Abstract: The conventional inverted T ceiling runner structure is used as a wall angle molding for a suspended ceiling system. Appropriate spacing means are utilized adjacent the vertical web of the inverted T runner to space the vertical web from a vertical wall so that the runner may be mounted in position with its horizontal flanges in a horizontal plane perpendicular to the wall.

Abstract: A suspended ceiling is installed in position by the use of a special nail construction. The nail has a pivotally mounted end which will maintain its straight configuration when it is being driven into a solid ceiling material. Should the nail be driven into a hollow ceiling material, the end of the nail will be permitted to pivot within the hollow area and the end of the nail then functions as a retainer to hold the nail in position in the ceiling material so that the suspended ceiling may be suspended from the retained nail.

Abstract: A splicer bar is provided for fastening together two inverted T-shaped runners. The splicer bar spans the junction between two runners and the splicer bar is fastened to the vertical web of both runners. Each runner has spaced apertures in its vertical web and the splicer bar has snap fasteners that will fit into these apertures to hold the two runners in parallel alignment and fixedly fastened together.
