A system and method for controlling an internal combustion engine for low emissions include an inner feedback control loop to control the engine fuel / air ratio with feedback provided by a first exhaust gas sensor and an outer feedback control loop that modifies a reference fuel / air ratio provided to the inner feedback control loop based on feedback signals provided by a second exhaust gas sensor positioned downstream relative to a portion of the catalyst and a third exhaust gas sensor positioned downstream relative to the second exhaust gas sensor. Catalyst gains are determined by modeling the catalyst as an integrator with an unknown gain and estimating the catalyst gain based on the exhaust gas sensors with the gain used to monitor catalyst performance and / or modify the engine fuel / air ratio.

An air spring for a heavy-duty vehicle axle / suspension system includes a bellows chamber operatively connected to a piston chamber. An opening is disposed between the bellows chamber and the piston chamber in order to allow fluid to communicate between the bellows chamber and the piston chamber. The cross-sectional area of the opening and the volumes of the bellows chamber and the piston chamber are tuned in order to optimize the damping characteristics of the air spring.

A razor handle having a body portion and a rigid head portion including a V-shaped pair of spaced arms, each arm having a reticulated structure having a first end for connection to the rigid head portion, a bearing member at a second end of the arm opposite the first end for connection to a razor head, and a pair of side walls connected by a series of transverse stiffeners.

Platen-mounted, post-mold cooling apparatus and method includes structure and / or steps for handling molded parts in an injection molding machine having a fixed platen, a moving platen, a core half, and a cavity half. A take off device coupled to the fixed platen is configured to remove molded parts from either the core half or the cavity half. A cooling device coupled to the moving platen is configured to cool the molded parts carried by the take off device. Preferably, the take off device extracts the just molded parts from the mold's core half and then moves linearly outboard of the mold halves. The subsequent movement of the moving platen to close the mold in the next molding cycle causes the cooling device's pins to engage the molded parts in the take off device part carriers. When the moving platen opens again, the molded parts are extracted from the part carriers by the cooling device pins. When the moving platen is fully open, the cooling device is rotated to eject the cooled parts from the machine.

A fuel system includes a fuel tank, a vent tank fluidically connected to the fuel tank ullage, the vent tank having a duct open to the ambient atmosphere and the interior of the vent tank, and a catalyst disposed in the duct, wherein the catalyst is adapted to deplete one or more reactive components of gas flowing through the duct by catalytic reaction. Also, a method for depleting one or more reactive components of gas in the fuel system, includes depleting one or more reactive components of gas flowing through the duct using the catalyst.

A printed circuit board (PCB) assembly is provided. The PCB assembly is adapted for mounting at least one heat-generating electrical device and providing integrated heat dissipating capability to dissipate heat generated by the electrical device. The PCB assembly has a top surface and a bottom surface and comprises a signal carrying layer and an insert of pyrolytic graphite (PG). The signal carrying layer, disposed between the top surface and the bottom surface, comprises a material that is both thermally conductive and electrically conductive (such as at least one of aluminum, copper, and silver and alloys thereof) and has at least a portion lying in a first plane. The insert of PG is disposed within at least a portion of the first plane of the signal carrying layer, is in thermal contact with the signal carrying layer, and is constructed and arranged to have its greatest electrical conductivity in the first plane. Optionally, a conductive via can be formed in portions of the signal carrying layer not occupied by the insert of PG, where the conductive via operably couples a first side of the signal carrying layer to a second side of the signal carrying layer.

A pressurized gas container associates with and supplies gas to a pressurized gas port of an appliance, such as for supplying carbon dioxide for the preparation of a carbonated drink. The container has a plug at its opening that has a barrier element that seals the container and is configured to be non-reversibly ruptured by a shaft of a gas-channeling member. The plug also has one or more sealing elements that are distinct from the barrier element and are configured for forming a gas-tight association with the shaft of the gas-channeling member. A plurality of such pressurized containers may be carried by a holder rack in a multipack. An appliance adapted for preparing or dispensing carbonated drink includes an adapter for associating with such a pressurized carbon dioxide-containing canister and for receiving the pressurized carbon dioxide therefrom.
