US Patent:

62347128, May 22, 2001

Filed:

Dec 4, 1999

Appl. No.:

9/454725

Inventors:

Michael E. Flader - Chicago IL
Anish A. Desai - Hoffman Estates IL
Jacob E. Steele - Chicago IL
Stephen M. Bednarz - DeKalb IL

Assignee:

Avery Dennison Corporation - Pasadena CA

International Classification:

E01F 906
E01F 908
E01F 1100

US Classification:

404 14

Abstract:

A snowplowable pavement marker includes a frame member having primary spaced keel members with ramp surfaces which have upwardly inclined contours beginning at a forward end portion of each keel member and extending at a first acute angle, then transitioning to a second portion having a second acute angle which is greater than the first angle. Further, the frame member includes an auxiliary keel member having ramp surfaces disposed between the primary keel members and having the same contour as the primary ramp surfaces. The auxiliary keel member ramp surfaces extend inwardly of the frame member to a point proximate the marker's reflector and serve to prevent damage by a snowplow blade set at a wide angle to the direction of blade travel. Advantageously, the contour of ramp surfaces permits a higher frame member installation above the pavement and allows for greater exposure of the reflector.

International Classification:

US Classification:

Abstract:

A turbine wheel for a turbocharger or the like is mounted to an impeller shaft and optionally an additional drive shaft by annular rows of coupling teeth preferably of the CURVIC. TM. coupling type having radially and rotationally locking convex sided and concave sided interlocking teeth. Flexible webs connecting coupling rings on the turbine allow thermo and mechanical growth of the turbine wheel without excessive deflection of the coupling rings and the associated shaft flanges. A single central stud threaded into one of the shafts and retained by a bolt against the other maintains the components in assembly with the coupling teeth fully engaged. A radial slot formed in the coupling flange for one of the shafts prevents thermal distortion of the flange from substantially affecting an adjacent thrust bearing portion of the flange. The arrangement simplifies rotor assembly and avoids the need for rebalancing after disassembly and reassembly. The full width of the coupling teeth are available for the transmission of torque and radial alignment forces.

International Classification:

F02M 25/07

US Classification:

12356812, 12356811

Abstract:

An engine system for a machine is disclosed. The engine system may have a first intake manifold configured to distribute air into a first cylinder bank of an engine. The engine system may also have a second intake manifold configured to distribute air into a second cylinder bank of the engine. The engine system may have a first exhaust manifold configured to discharge exhaust from the first cylinder bank to the atmosphere. The engine system may further have a second exhaust manifold configured to discharge exhaust from non-donor cylinders in the second cylinder bank to the atmosphere. In addition, the engine system may have a third exhaust manifold separate from the first and second exhaust manifolds and configured to recirculate exhaust from donor cylinders in the second cylinder bank to the first and second intake manifolds.

Appl. No.:

13/465531

Inventors:

Pradeep K. GANESAN - Chicago IL, US
Stephen M. Bednarz - De Kalb IL, US

International Classification:

B01D 46/42

US Classification:

553853, 55419

Abstract:

An exhaust system is disclosed. The exhaust system may have a plenum configured to receive exhaust from an engine. The exhaust system may also have a first filter bank having a plurality of filter assemblies and configured to receive a first flow of exhaust from the plenum. The exhaust system may further have a second filter bank having a plurality of filter assemblies and configured to receive a second flow of exhaust from the plenum. In addition, the exhaust system may have a distribution device located between the first and second filter banks. The distribution device may have a plurality of perforations. A porosity of the distribution device may be configured to selectively distribute exhaust to the plurality of filter assemblies.
