Publication number: 20050247049Abstract: The invention relates to systems for removing NOx from exhaust. In one aspect of the invention, after adsorption, an NOx adsorber is isolated from the main exhaust flow and desorption induced by raising the temperature. The desorbed NOx is combined with a reductant and reduced over a catalyst. Preferably, the reductant is syn gas produced in an on-board reformer. The catalyst need never be exposed to the main exhaust flow, which is particularly advantageous for catalysts sensitive to water, oxygen, or sulfur. In another aspect of the invention, a recirculating flow is induced through an NOx adsorber during a regeneration cycle. Recirculation can induce greater desorption at a given temperature, provide a source of heat for the adsorber, and allow a higher conversion rate with a fixed amount of catalyst. A further aspect of the invention relates to a vehicle-mounted adsorbers with provisions for heating.Type: ApplicationFiled: May 5, 2004Publication date: November 10, 2005Applicant: Eaton CorporationInventors: Wayne Kaboord, Dawn Becher, Fred Begale, Daniel Fellers, John Kovacich, Steven Kuznicki

Publication number: 20050249645Abstract: The present invention provides adsorbers with a high spatial and/or mass density of usable adsorbant in configuration suitable for vehicle exhaust systems. One aspect of the invention relates to an adsorber or catalyst having a monolith structure and porous walls. The walls have a void volume of at least about 0.1 exclusive of pores having a diameter less the 1 ?m. Another aspect of the invention relates to an adsorber or catalyst having a bed comprising porous pellets fused together to form a cohesive mass. A further aspect of the invention relates to an adsorber or catalyst having a bed comprising coated wire screens. A still further aspect of the invention relates to an adsorber or catalyst having a small number of channels, preferably just one central channel, for heating and cooling.Type: ApplicationFiled: May 5, 2004Publication date: November 10, 2005Applicant: Eaton CorporationInventors: Wayne Kaboord, Dawn Becher, Fred Begale, John Kovacich

Patent number: 5559280Abstract: A transducer housing for mounting a port in a combustion chamber has a metal diaphragm exposed to the combustion gasses. The pressure of the combustion gasses deflects the diaphragm which locally deflects a simply supported beam. The beam is formed of refractory material having epitaxially grown crystalline piezoresistors formed on one surface of the beam and connected in a bridge circuit. Noble metal foil leads connect to the piezoresistors to form the bridge and provide attachment pads. The pads are noble metal welded to other noble metal foil pads provided on a ceramic substrate to form a sensor subassembly for mounting adjacent the diaphragm to form a transducer.Type: GrantFiled: November 14, 1994Date of Patent: September 24, 1996Assignee: Eaton CorporationInventors: John A.

Patent number: 5328551Abstract: A method of making a foil-type electrical resistance strain gage having a gage factor of at least 4. A PtW foil is adhesively bonded to a polyimide substrate with an FEP adhesive cured under heat and pressure. The foil is spin-coated with a positive photoresist, masked, and exposed to ultraviolet light. The exposed photoresist is then developed, permitting wet etching of the foil to form a gage pattern on the substrate, which is then preferably cured.Type: GrantFiled: October 28, 1992Date of Patent: July 12, 1994Assignee: Eaton CorporationInventor: John Kovacich

Patent number: 5264820Abstract: A pressure transducer for measuring high differential pressure media in a harsh environment where a diaphragm assembly is mounted to an intermediate support number which is mounted to a main support member where the high pressure media impinges on the diaphragm to create a force opposing that provided by the diaphragm support structure thereby loading the diaphragm in compression. The strain sensitive piezoresistive elements are protected and sealed from the low pressure media by a passivation layer and electrical signal leads are attached to bonding pads formed on the diaphragm assembly which are sealed to the intermediate support member by a sealing cap.Type: GrantFiled: March 31, 1992Date of Patent: November 23, 1993Assignee: Eaton CorporationInventors: John A.
