Abstract: A modular electrical assembly including a plurality of conductive electrical components aligned in a column along an axis and electrically connected at axially directed ends. First and second conductive end members are located at opposite sides of the column, the end members having shoulders extending radially relative to the axis, each shoulder having an outer surface facing radially outwards. A non-conductive winding is wrapped in a predetermined pattern about the electrical components and the end members, engaging the shoulders, and applying an axially directed compressive force through the shoulders on the electrical components and end members to maintain electrical connection therebetween. A housing encompasses the winding, while a strip, located between the housing and the winding, covers the outer surface of the first end member to protect the housing from contact with the outer surface of the shoulders. The strip also covers voids between the first end member and the non-conductive winding.

Abstract: An insulator conveys cooling fluid for or connects an optical fiber cable to an outdoor high voltage electrical system. The insulator includes an elongated pipe of non-conductive material having an internal passageway through it for the cooling fluid or optical fiber cable. An elongated weathershed housing surrounds and covers the outer surface of the pipe. Couplers, located at the opposite ends of the pipe connect conduits for conveying cooling fluid into and out of the fluid passageway or passing the cable. The insulator can be connected between an electrical device and a heat exchanger through connectors such that cooling medium can pass from the heat exchanger at ground potential up through the insulator which also supports the device and into the device for cooling the device.

Sections of two adjacent paths are in close proximity and cross each other between the input and output terminal. At least two of the paths have sets of vias connected in series between the input and output terminals. The sets of vias are adjacent.

Abstract: A lighting fixture housing has a lamp cavity and two electrical sockets adjacent the opposite sides of the housing in the lamp cavity. Side barriers are adjacent the opposite sides and overlie the sockets such that each socket is located between a barrier and a housing side and is recessed behind the barrier by a distance. Lamp receiving openings in the barriers are coaxially aligned with the sockets to permit a lamp to extend through the openings and connect the lamp to the sockets. A channel in one barrier has a first portion extending along a peripheral edge of the barrier and a second portion extending from the first portion and terminating in the lamp receiving opening of the barrier.

Abstract: A switched outlet having a dead front includes a housing, an electrical receptacle mounted in the housing for receiving an electrical plug, a switch mounted in the housing, a handle coupled to the housing and movable between on and off positions, and a switch actuating mechanism. The switch actuating mechanism is coupled to the switch for activating and deactivating the switch. A clutch engages or disengages the handle and the switch activating mechanism. The clutch engages the handle and the switch actuating mechanism when an electrical plug is fully inserted in the electrical receptacle. The clutch disengages the handle from the switch actuating mechanism when no electrical plug is fully received in the electrical receptacle.

Abstract: A packaging display system includes a first set of cartons packaging a first group of products and a second set of cartons packaging a second set of products. Each of the sets and groups are divided into subsets and sub-groups. The products of the first group are selectively matable with the products of the second group, with only some of the first sub-groups products properly mating with only some of the second sub-group products but not with other products of the second sub-groups. Color coding is provided on the cartons for indicating which of the products of the first; sub-groups properly mate with the second sub-group products. The color coding includes patches of different colors with a same color patch appearing on the cartons of the first and second sub-groups packaging products of the first and second sub-groups which properly mate.
