Abstract: A modular wiring system is disclosed for lighting and power distribution in office buildings, factories and the like. The modular wiring system utilizes a five-face connector assembly as its principal component for the distribution and control of power to lighting fixtures and power receptacles. The connector assemblies may be one of four types for providing different power configurations at the connector faces. The five-face connector assemblies all utilize the same housing and are economical to manufacture by using specially designed bus bars to obtain the desired power configurations and to provide the terminal connections. Other components of the wiring system mate with the five-face connector assembly to provide an efficient lighting or convenience power system which may be easily field modified.

Abstract: A unitary insertable self-anchoring poke-thru wiring device for building construction includes a tombstone outlet box dimensioned to overlie and conceal a standard floor aperture opening into an occupied space, hollow elongated conduit means extending through the aperture, a narrow elongated junction box dimensioned to pass lengthwise through the aperture and anchored to the conduit means, fire-retardant means centrally anchored to the hollow conduit means positioned inside the aperture, and a conically-dished resilient spring washer encircling and anchored to the hollow conduit means adjacent to the fire retardant means and having its conical surface concavely diverging toward the outlet box, with its periphery notched and dimensioned for wedging engagement in the standard aperture, the poke-thru wiring device thus being adapted for unitary insertion from the occupied space into the aperture, with the resilient spring washer wedgingly engaging the internal wall of the standard aperture retaining the wiring d

Abstract: A high frequency self-contained emergency lighting fluorescent pack is exteriorally mountable to a fluorescent fixture either in line with a fluorescent lamp having a length shorter than that normally installed in the fluorescent fixture or in a side-by-side relationship near the fluorescent lamp. In either configuration, the emergency lighting fluorescent pack de-energizes all electrical connections when the interconnected fluorescent lamp is not properly in place, and only energizes the electrical connections when the fluorescent lamp is properly installed.The emergency lighting fluorescent pack incorporates a battery pack, a battery charger for maintaining the batteries in the battery pack at full charge, a high frequency emergency power generating inverter module for igniting and maintaining the fluorescent lamp in the illuminated state by energy supplied by the battery pack, and transfer circuitry for causing the energization of the emergency power module by the battery pack when utility AC power fails.

Abstract: The color-coded index tab is produced automatically by passing a tape through a label applying machine which is programmed by a computer to apply color-coded labels at precise locations of the tape. The tape is afterwards severed to produce the individual index tab for subsequent application to a file holder. The index tabs can be folded or not about the longitudinal center line so that the block of color on each label can be exposed around the edge of the file holder or on a flat edge surface of the file holder for viewing purposes. The individual index tabs and labels can be sized to present any number of different color coded blocks.

Abstract: A shelf couple assembly for mounting shelves on walls, wall studs, or rafters utilizes a unitary shelf-gripping couple having a protruding cantilever platform with raised rearward and forward portions and downwardly projecting barbs for fixedly supporting a shelf board between these raised portions and barbs. The assembly also incorporates a shelf trim channel that is snapped onto adjoining shelf boards to align them and to provide a visually unitary appearance. Furthermore, the assembly incorporates a rear shelf clip which may be driven into a wall-board, stud, or rafter for supporting the rearward portion of two adjoining shelf boards or for adding support to a section of shelf board that is heavily loaded. In addition, a cover is incorporated in the assembly that fits over the unitary shelf couple and thus conceals it while enhancing the overall appearance of the shelf couple assembly.

Abstract: By providing a frame structure and two panels adapted for removable, interlocking mounting on the frame structure, a sign housing is obtained which is rapidly assemblable without the use of screws, clips, or other such fastening means. In the preferred embodiment, the sign housing is employed as an illuminated emergency exit sign, and can be flush-mounted with only one side viewable or mounted to ceilings or walls with both sides viewable. Also, an emergency power supply can be secured directly to the sign housing to provide a complete independent package.
