Patent number: 9938875Abstract: Apparatuses and methods for urea dosing of an exhaust after treatment system are disclosed. Exemplary apparatuses include a chamber configured to receive pressurized gas at a first inlet, receive urea solution at a second inlet and provide a combined flow of pressurized gas and urea to an outlet, flow passage extending from the first inlet to a seating surface, and a valve member configured to move between an open position in which the valve member is spaced apart from the seating surface and a closed position in which the valve member contacts the seating surface. As the valve member moves from the open position to the closed position, the valve member contacts the seating surface at a first location and wipes an area of the seating surface extending from the first location in a direction toward the flow passage.Type: GrantFiled: July 19, 2016Date of Patent: April 10, 2018Assignee: CUMMINS EMISSION SOLUTIONS, INC.Inventors: Andrew Myer, Chetan Ponnathpur, John Heichelbech, George Muntean, Stephen Holl, James F.

Patent number: 9926822Abstract: An exemplary embodiment includes a blending chamber having a urea inlet, a blending chamber gas inlet, and a blending chamber outlet. A urea source provides a pressurized urea solution to the urea inlet at a urea injection pressure, and a pressurized gas source transmits pressurized gas to the blending chamber gas inlet via a passageway. The passageway is configured to decrease pressure of the pressurized gas transmitted along its length from a first pressure of gas received from the pressurized gas source to a second pressure of gas provided to the blending chamber gas inlet. The first pressure of gas received from the pressurized gas source is greater than the urea injection pressure and the second pressure of gas provided to the blending chamber gas inlet is less than the urea injection pressure.Type: GrantFiled: August 16, 2013Date of Patent: March 27, 2018Assignee: CUMMINS EMISSION SOLUTIONS, INC.Inventors: George L. Muntean, Steve Holl, Joydeep Chakrabarti, John Anthis, Joshua D. Henry, Samuel Johnson, Andrew Myer

Patent number: 9470129Abstract: A reductant delivery system is provided for delivery of reductant to an engine exhaust aftertreatment system that is heated during cold temperature conditions. A heat exchange fluid flows through a heat exchange circuit that provides a flow path from the heat source to the doser, from the doser to the reductant storage tank, and from the reductant storage tank to the heat source. A control valve controls the flow of the heat exchange fluid in the heat exchange circuit so that at least one heat exchange cycle includes a circulation period that increases the temperature of the reductant in the doser and storage tank and a termination period where circulation is stopped until reductant temperature in the doser reaches a lower limit.Type: GrantFiled: January 16, 2015Date of Patent: October 18, 2016Assignee: CUMMINS EMISSION SOLUTIONS INC.Inventors: Andrew Myer, John Heichelbech, Stephanie Apewokin, Stephen Holl, James F.

Patent number: 9387707Abstract: A paper tape printer includes a receipt printer and a scissor cutter for cutting off a receipt from a paper tape. The scissor cutter includes: a moving blade having a fixed range of motion; and an adjustable stationary blade, which is stationary during a cutting operation and is moveable laterally relative to the moving blade to allow the paper tape to be selectively (i) fully cut when the stationary blade is positioned for a full cut of the paper tape, or (ii) partially cut, when the stationary blade is repositioned laterally to a partial cut position relative to the moving blade, which enables a partial cut of the paper tape. If a full cut is desired, the stationary blade is positioned against the full width of the paper tape. For a partial cut, the stationary blade is positioned against only a portion of the width of the paper tape.Type: GrantFiled: March 10, 2014Date of Patent: July 12, 2016Assignee: Toshiba Global Commerce Solutions Holdings CorporationInventor: Robert Andrew Myers
