A method and apparatus for spin forming a portion of a workpiece includes at least two rollers rotatable about a spin axis. Each one of the rollers is axially and radially offset from the others. An axial drive mechanism reciprocates the rollers or workpiece to causes the first roller and then the second roller to sequentially engage the workpiece. A higher reduction ratio is achieved which enables improved efficiency. The present invention reduces floor space requirements as the forming operation may be completed on a single machine.

Method and apparatus for lean spin forming

Disclosed herein is a method for reducing internal combustion engine contaminate and additive particulate matter from a particulate filter the method including accessing the filter and entraining particulate matter in a fluid stream. Further disclosed herein is an internal combustion engine particulate filter system including a canister, a filter media mounted in said canister and an access opening in said canister. Yet still further disclosed herein is a method for determining condition of a particulate filter in situ including establishing a vacuum value for a clean particulate filter in situ, establishing a vacuum value for a used particulate filter in situ; and comparing the established value for the clean filter versus the used filter.

Diesel particulate filter ash removal

A method and apparatus for spin forming a portion of a workpiece where the formed portion has a formed axis that is non-coaxial with the non-processed axis of the workpiece includes at least two rollers rotatable about a spin axis. Each one of the rollers is axially and radially offset from the others. An axial drive mechanism reciprocates the rollers or workpiece to causes the first roller and then the second roller to sequentially engage the workpiece. A pivoting mechanism rotates the rollers or workpiece about a pivot point from a first angular position to a second angular position during a forming operation to create a formed portion that is oblique to the non-processed portion or is substantially curved. A higher reduction ratio is achieved which enables improved efficiency. The present invention reduces floor space requirements as the forming operation may be completed on a single machine.
