Abstract: A weather resistant cabinet for housing electrical equipment includes a one-piece, unitary tubular housing. The tubular housing has two open ends and is preferably formed from aluminum using a deep-drawing process. Two covers are attached to the two open ends of the tubular housing. The two covers include heat sinks and are preferably formed from aluminum using an extruding process. The covers are attached to the tubular housing using either mechanical fasteners and a gasket, or by a dip-brazing process.

Abstract: A cabinet includes a hinged tracking system for attaching a door to the cabinet. The hinged tracking system allows the door to translate rectilinearly away from the cabinet, as well as rotate with respect to the cabinet. The hinged tracking system includes a track member attached to a side wall of the cabinet, and a slide member slidable with respect to the track member. An intermediate member may be disposed between the track member and the slide member to increase the linear travel of the slide member. A hinge is located between the slide member and the door. The track member and the slide member may include stoppers which prevent overtravel of the slide member with respect to the track member, so that the slide member does not inadvertently slide completely off of the track member. The slide member may also include a locking system for locking the slide member in a maximum extended position, and for locking the hinge in a closed position or an open position.

Abstract: A mounting assembly includes a metallic base member, such as a wall of an enclosure. A threaded stud is fused to the base member. A threaded collar engages the threaded stud and provides a threaded recess for receiving a mounting fastener. The mounting assembly is well-suited for supporting electronic items within an enclosure in a weather-tight or water-proof manner because the mounting assembly requires no seals for an environmental barrier.

Abstract: A holder for a pair of cylindrical battery cells includes a carrier which retains the batteries in parallel side-by-side relationship and in series electrical connection. The cells are installed into a housing longitudinally and the housing is formed with guide channels for guiding and substantially surrounding the cells. At the ends of the guide channels, there are provided contact elements for electrically connecting the battery cells to circuitry. Electric shock hazard to a user is eliminated because the internal contact elements are inaccessible to the operator, even when the carrier is removed from the housing.
