A gasket for an internal-combustion engine is designed to seal between an engine block and a cover of the internal-combustion engine. The gasket includes a plurality of members that are metal and a layer of elastomeric material on the members. The elastomeric layer includes joints between the members. The joints allow the gasket to flex to accommodate potential variation in sealing surface of the engine block without bending of the members.

A mood indicating assembly includes a housing that is positionable on a support surface. A plurality of light bars is each disposed on the housing to emit light outwardly from the housing. Each of the plurality of light bars is independently actuatable ranging between a minimum number of the plurality light bars and a maximum number of the plurality of light bars. In this way the plurality of light bars facilitate a user to visually communicate an intensity of their mood to a colleague. Each of the plurality of light bars emits light of a unique color with respect to each other to facilitate the user to visually communicate their stress level to the colleague thereby facilitating the colleague to choose to avoid disturbing the user.

A multi-layer metal gasket includes a first functional layer and a second functional layer. A bore and a fastener hole extend through the first and second functional layers. The first functional layer has a first embossment protruding toward the second functional layer and the second functional layer has a second embossment protruding toward the first functional layer. The first embossment and the second embossment each encircle the bore. An intermediate layer is between the first and second functional layers. The intermediate layer extends between the first embossment and the second embossment and extends from the first and second embossments to the fastener hole. A spacer layer is between the intermediate layer and the first functional layer. The spacer layer has an inner edge defining a hole through the spacer layer. The inner edge encircles the first embossment. The spacer layer extends from the inner edge to the fastener hole.

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.

An improved gasket assembly including a core layer and at least two facing layers disposed on opposite sides of the core layer is provided. The gasket assembly further includes first and second outer layers which are made of metal and are disposed on opposite sides of the facing layers from the core layer. The core, facing and outer layers all present at least one set of axially aligned openings. The first layer is bent towards the second layer by no greater than ninety degrees at the openings to present a first outer layer flange, and the second layer is bent by no greater than ninety degrees at the openings to present a second outer layer flange. The first and second outer layer flanges are in direct contact with one another to provide a gas tight seal around the set of axially aligned openings.

Multi-layer gasket assembly

A multi-layer cylinder head gasket is provided. The cylinder head gasket includes a plurality of layers of material, each of the layers has a plurality of openings including at least one cylinder bore opening and at least one pushrod opening. Each of the layers has an edge which surrounds the at least one pushrod opening, and the pushrod openings of the layers are aligned axially with one another. An eyelet extends axially in each of the pushrod openings and covers the edges of the layers for protecting a pushrod extending through the respective pushrod opening. The eyelet is made of a material that is softer than the material of the plurality of layers.

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.
