Publication number: 20150211406Abstract: An after-treatment system includes a Selective Catalytic Reduction (SCR) catalyst or a similar aftertreatment unit or brick that may be inserted into the opened end of a sleeve. The aftertreatment brick includes a substrate matrix with catalytic material that extends between a first face and a second face. A mantle is disposed around the substrate matrix and extends between a first rim proximate the first face and a second rim proximate the second face. The mantle may include a overhang extension that extends the first rim of the mantle beyond the first face of the substrate matrix. To enable retrieval of the SCR catalyst from the sleeve, a retrieval feature is disposed on a readily accessible, inner surface of the overhang extension.Type: ApplicationFiled: April 6, 2015Publication date: July 30, 2015Applicant: CATERPILLAR INC.Inventors: Mirza P. Baig, Thomas W. Manning, Rick E. Jeffs, Kristian N. Engelsen, Andrew M. Denis, Pradyumna V. Rao

Patent number: 9050559Abstract: An aftertreatment system and method treats exhaust gasses produced by an internal combustion process or a similar process. The aftertreatment system includes an aftertreatment module having a sleeve extending between a first end and a second end. One or more aftertreatment bricks are axially inserted into a sleeve opening disposed in the first end of the sleeve. To prevent the aftertreatment bricks from unintentionally exiting the sleeve, a captive ring is disposed around the first end of the sleeve as a loose fitting collar. The captive ring is restrained on the sleeve by a circumferential bead protruding about the first end. The captive ring can couple with a retention ring placed adjacent the first end. When coupled to the captive ring, a portion of the retention ring extends partially across and blocks the sleeve opening, preventing the aftertreatment brick from exiting the sleeve.Type: GrantFiled: March 1, 2013Date of Patent: June 9, 2015Assignee: Caterpillar Inc.Inventors: Andrew M. Denis, Thomas W. Manning, Ian Aguirre, Rick E. Jeffs, Nagaraju Manchikanti

Patent number: 7527216Abstract: An apparatus and method for unwinding yarns with: (1) a drive roll with a polished metal finish to ensure good fiber/metal contact; (2) a drive roll/separator roll combination that enables multiple wraps of yarn on the drive roll; (3) pivoting yarn holding arms for the active and standby packages that provide for easier access to the packages on a frame; and (4) in combination with the pivoting yarn holding arms, one or more pivoting legs extending from a frame so that the apparatus has a relatively small footprint and simplified yarn threading/string-up as compared to background art OETO apparatus.Type: GrantFiled: July 15, 2005Date of Patent: May 5, 2009Assignee: INVISTA North America S. ar. l.Inventors: Thomas W. Manning, Jr., Ronald D. Bing-Wo

Publication number: 20080283653Abstract: A compact continuous over end take-off creel system with a tension control apparatus permits unwinding of high tack elastomeric threads from multiple thread packages. Thread tension is monitored and controlled through a variable speed motor of a driven take-off roll to maintain continuous operation of the creel system by avoiding breakage of elastomeric threads. Separate motors and thread tension sensors, optionally in combination with pretensioners, may be used for groups of threads or for individual threads.Type: ApplicationFiled: April 18, 2008Publication date: November 20, 2008Applicant: INVISTA North America SARLInventors: Ronald D. Bing-Wo, Thomas W. Manning

Patent number: 5042734Abstract: An improved cantilevered lay-on drive roll assembly is provided for high speed winding of threadlines on separable yarn packages which are supported on a common cantilevered chuck. The assembly has a deflectable coupling which connects the drive shaft to the roll shell and spaced bearings for rotating the shell on a cantilevered support.Type: GrantFiled: April 27, 1990Date of Patent: August 27, 1991Assignee: E. I. Du Pont de Nemours and CompanyInventors: Richard J. Angelucci, Thomas W. Manning, Jr., James F. McKinney, William D. Walker
