Filed:

Dec 15, 2001

Appl. No.:

10/023284

Inventors:

Donald P. Kenney - McFarland WI, US
Donald A. Gibson - Stoughton WI, US
Randy E. Craig - Brooklyn WI, US

Assignee:

Fe Petro, Inc. - McFarland WI

International Classification:

F04B 17/03

US Classification:

417366, 4174233

Abstract:

A submersible pump-motor assembly for use in dispensing petroleum from petroleum storage tanks. The pump-motor assembly of the present invention enhances the performance characteristics of the pump-motor assembly by providing greater flow area around the motor stator while maintaining the alignment of the assembly's critical pump components. Such enhanced pump performance characteristics provide the petroleum dispensing station manager using such pump-motor assemblies with greater flow rates per dispenser or, when maximum flow rates are capped, potentially greater dispensing capacity.

Appl. No.:

12/077133

Inventors:

Donald A. Gibson - Stoughton WI, US

Assignee:

Cummins Filtration IP, Inc. - Minneapolis MN

International Classification:

F01N 3/00

US Classification:

60286, 60274, 60296, 60303

Abstract:

An apparatus is disclosed for increasing the residency time of a reducing agent in an exhaust gas cleaning system. The apparatus includes a first double-walled element in communication with a flow of exhaust having a first inner wall and a first outer wall. A second double-walled element is included having a second inner wall and a second outer wall. The second double-walled element is arranged in relation to the first double-walled element such that the second inner wall is positioned between the first inner wall and the first outer wall and the first outer wall is positioned between the second inner wall and the second outer wall. This arrangement defines a plurality of flow paths that reverses the flow of exhaust back on itself and then reverses the flow of exhaust once again.

International Classification:

B21D 51/16

US Classification:

2989008, 29 33 D, 29 33 T, 29234, 72 164, 72 37, 180 892, 180296, 180309

Abstract:

An apparatus for designing a tubing configuration comprising modules that receive tube design input, interpret a tube design input, calculate a final tube design, and display a final tube design. The tube design input may include point locations, bend criteria and end conditions, among others. The apparatus may further include modules that determine whether the tube design input exceeds a complexity threshold, comprises a minimum set of information, and comprises a conflicting or erroneous design. The apparatus may further include modules that determine and optimize the manufacturing cost as well as determine the manufacturability of the tube. The apparatus may further include modules that store operational challenges corresponding to emissions reduction features and secondary components.
