20100015829 | Separable Loadbreak Connector and System for Reducing Damage Due to Fault Closure - Separable loadbreak connectors include an interference element spaced about the contact tube that is configured to engage a portion of a connector piston. | 01-21-2010 |
20100014273 | Fusible Switching Disconnect Modules and Devices - A fusible disconnect device having auxiliary connections to line-side and load-side terminals and color coding features to indicate an amperage rating of a fuse. | 01-21-2010 |
20100002452 | Luminaire housing with separated lamp and ballast compartments - A luminaire housing with a lamp compartment and ballast compartment that are isolated from each other is provided. The housing includes a lamp compartment, a ballast compartment, and an air gap chamber separating the two compartments from each other. The air gap chamber provides a degree of thermal isolation that reduces the amount of heat generated by the lamps that is transferred from the lamp compartment to the ballast compartment. The luminaire can also include a ventilated top cover and a bottom door configured to attach to the lamp compartment while leaving an air gap therebetween. These and other optional features improve the air circulation within the lamp compartment and allow heat generated by the lamps to exit the luminaire housing, further reducing the heat transferred to the ballast compartment, thereby improving the lifespan and performance of the ballasts. | 01-07-2010 |
20100001166 | Method and Apparatus for Improving the Strength of a Utility Pole - A support pole with enhanced strength along it's base includes an elongated pole member secured to a mounting plate. A majority of the length of the pole member has a uniform cross-section. Slits are cut into each side of the pole member along its lower end. A mandrel is placed into the lower end of the pole and expanded, thereby expanding the lower end of the pole away from the center and creating a larger cross-sectional area at its lower end. The lower end of the pole is secured to the mounting plate. Reinforcing members are welded over the expanded slits and the bottom of the reinforcing member is further welded to the mounting plate. The lower section with a larger cross-sectional area increases the moment of inertia and surface area of the support pole, thereby increasing the strength of the support pole. | 01-07-2010 |
20100000783 | FLOOR STAND FOR MOUNTING AN ELECTRICAL BOX - A floor stand is disclosed for mounting an electrical box at a location above a floor between two wall studs. The floor stand has an elongate sheet metal body and at least one mounting arm attached to the body. In one embodiment, the mounting arm is bendable from a position extending lengthwise of the body to a position in which it extends generally laterally outward from the body for attachment to one of the wall studs. In another embodiment, the two mounting arms are detachable from the body and re-attachable in the stated second position. An optional cable-containment section for connection to the box-mounting section of the floor stand is also disclosed. | 01-07-2010 |
20090321598 | Luminaire quick mount universal bracket system and method - A luminaire system provides for mounting and accessing a light fixture housing without tools. A universal bracket is coupled to the junction box along the ceiling and engages with a top mounting plate affixed to the housing. One or more slide hooks appended to the universal bracket allows the top mounting plate to mount to the universal bracket, and a reinforced spring and locking spring keeps the light fixture housing in place, while preventing rattling between the universal bracket and the top-mounting plate. The housing can be removed from the electrical junction box through the use of a release button affixed to the housing. The button disengages the locking spring from the top mounting plate, thereby allowing the housing to swivel away from the universal bracket and junction box by way of a hanging hook. The hanging hook supports the housing when released from the universal bracket. | 12-31-2009 |
20090310361 | Luminaire with Integral Signage Endcaps - A luminaire with signage endcaps includes a luminaire housing and one or more light emitting elements. The housing typically includes a top member and multiple side members extending down from the top member. The top and side members define the interior of the luminaire housing. Light emitting elements are coupled to the housing. These light emitting elements generally emit light downward from the luminaire and can be coupled along the interior of the housing or positioned along an exterior side of one or more of the side members. A stencil or stencil plate can be positioned along or coupled to one or more others side members. The stencil and stencil plate include openings in the shape of alphanumeric symbols and/or ideograms and include within the openings or have positioned adjacent to the openings a translucent member. Ambient light within the interior of the housing illuminates the stencil and translucent member. | 12-17-2009 |
20090310330 | Combination Luminaire and Path of Egress Lighting - A combination luminaire and path of egress lighting includes a lamp housing and one or more auxiliary lamps. The lamp housing includes an electrical enclosure, a lamp mounting area and a lamp cover. A primary light source is positioned within and coupled to the lamp housing. The auxiliary lamps are coupled to and extend out from the exterior of the lamp housing. Each auxiliary lamp typically include a base plate, a stem member, and a task lamp housing. The base plate is coupled to the exterior of the lamp housing. The stem rotatably coupled on one end to the base plate and along the other end to the task lamp housing. By rotatably coupling auxiliary lamp along each end of the stem member, the task lamp housing has a large range of adjustability so that it can be aimed towards paths of egress after the luminaire is installed. | 12-17-2009 |
