Abstract: One embodiment permits retrofitting one or more laterally extending electrical boxes for extra switches, outlets or accessories such as rheostatic controls in existing walls without tearing out a portion of the wall, removing the box, rewiring a new ganged box and refinishing the wall. This invention provides modular lateral box extensions constructed to be installed from the open front end and supported by the installed box anchored to a beam with the wall being cut only enough to receive the extension modular box. This efficiently requires the wiring of only additional modules and avoids repair and repainting of walls.

Abstract: In a multi-functional multilayer device including a body (10) having a varistor section (2) and a capacitor section (3) stacked and integrated therewith, the adhesion between a varistor layer and a dielectric layer is improved when the varistor layer (22) contains zinc oxide as a main component and at least one lanthanide oxide as an auxiliary component, and the dielectric layer (32) contains titanium oxide or lanthanum/titanium oxide as a main component. The device experiences little warpage upon firing when glass is added to the dielectric layer. A high resistivity intermediate layer (5) disposed between the varistor and capacitor sections (2 and 3) prevents the deterioration or loss of varistor and capacitor properties by interdiffusion of elements between the varistor and capacitor sections.

Abstract: An electric power busway system comprises a bus bar support housing with the opposite side plates of the housing shaped with troughs to hold the bus bars in their relative positions, preventing the bus bars from moving towards or away from one another and providing the necessary short-circuit protection and bending resistance. The metal side plates are preferably fastened together without the use of fasteners or the need for welding, through the use of a punch and die tool set. A protective insulating sheet is sandwiched between the insulated bus bars and the housing to protect the bus bar insulation coating from ruptures or tears. Clamping blocks are provided outside the protective busway housing to apply friction on the bus bars within, keeping them from sliding out of the housing assembly. The integral busway housing and clamping serve as a ground conduction facility, with the clamping blocks providing a mechanism to connect the busway section to an adjoining section.
