Abstract: A shaft seal assembly for establishing a liquid-tight seal between a steering knuckle and an axle shaft is provided. The shaft seal assembly includes an outer case and a first elastomeric member attached to one another. The elastomeric member has a castellated feature including a plurality of projections extending in a radially outward direction and separated from one another by a plurality of grooves. When the shaft seal assembly is installed in the steering knuckle, a cavity is presented between the steering knuckle and the first elastomeric member. Together, the grooves and cavity allow air to flow from a hub on one side of the seal assembly to a vacuum port in the steering knuckle. The cavity extends circumferentially around the seal assembly, and thus, air flow from the hub to the vacuum port is not dependent upon the orientation of the seal assembly relative to the steering knuckle.

Abstract: A gasket body has a combustion opening and a coolant opening close to the combustion opening to define a narrow region of the gasket between the openings. An inner armor layer has an inner C-shaped section folded over an edge of the combustion opening adjacent to the coolant opening. The inner armor layer has top and bottom portions extending over the top and bottom surfaces of the narrow region of the gasket body. An outer armor layer has an outer C-shaped section folded over the inner C-shaped section. The outer armor layer has top and bottom portions extending over the top and bottom portions of the inner armor layer. The bottom portion of the outer armor layer extends across the entire width of the bottom surface of the narrow region of the gasket body and has a second C-shaped section folded up and over an edge of the coolant opening adjacent to the combustion opening.

Abstract: An enclosure for drawout circuit interrupters having instrumentation and control wiring includes a housing having circuit interrupter recesses; wiring tray recesses; wiring trays each of which hold the wiring for one of the circuit interrupters; drawout mechanisms for removing the trays from the tray recesses; and brackets for hanging the trays from the enclosure. The trays may have a molded plastic front panel. The trays may also have internal lances or holes for securing the wiring thereto, two rear holes for routing the wiring therethrough, and a bottom side having holes for mounting rails for securing terminal blocks or fuse blocks thereto. The rear holes may hold peripheral plastic conduits for protecting the wiring. The front panel may have recess pockets for holding a descriptive nameplate, and center punches to facilitate mounting instrumentation or control devices. The drawout mechanisms may have a rectangular guide bar beneath the trays.
