Patent number: 10830117Abstract: An exhaust aftertreatment assembly and method of manufacturing and operating an exhaust aftertreatment assembly. An exhaust aftertreatment assembly includes an aftertreatment housing and an inlet conduit coupled to the aftertreatment housing at an inlet port so as to transfer exhaust gas into the aftertreatment housing. An inlet chamber is positioned in the aftertreatment housing. The inlet chamber is fluidly coupled to the inlet port of the aftertreatment housing to receive the exhaust gas from the inlet conduit.Type: GrantFiled: December 22, 2015Date of Patent: November 10, 2020Assignee: Cummins Emission Solutions Inc.Inventors: Randolph G. Zoran, David M. Sarcona, Ryan M. Johnson, Enoch Nanduru

Patent number: 5125326Abstract: A three position actuator which is used to position the gear range control lever on a two speed transfer case. Three positions are required to achieve HIGH, LOW and NEUTRAL. Two individual air chambers may be selectively charged with compressed air to move two pistons along a common actuator rod to achieve linear translation of the control lever to selectively position the transfer case in HIGH, NEUTRAL or LOW range. The transfer case is shifted from LOW to NEUTRAL or HIGH to NEUTRAL by releasing the respective charge of compressed air thereby permitting a spring to shift the control lever to neutral. Thus, in the event of a failure of the system supplying the compressed air, the actuator will return the transfer case to NEUTRAL as required for towing.Type: GrantFiled: January 29, 1991Date of Patent: June 30, 1992Assignee: Rockwell International CorporationInventor: David M.
