Patent number: 11333446Abstract: A seal assembly includes a leaf assembly and a supplemental leaf assembly. The leaf assembly includes a first leaf having a first base section. The first base section defines a first fastening area for securing the first leaf to a diaphragm of the preheater. The first leaf has a first elongate section extending away from the first base section and terminating at a first distal end thereof. The leaf assembly further includes a second leaf that engages a portion of the first leaf. The second leaf has a second base section. The second base section defines a second fastening area for securing the second leaf to the diaphragm. The second leaf has a second elongate section extending away from the second base section and terminating at a second distal end thereof. The supplemental leaf assembly is secured to the first leaf and slidingly engaging the second leaf.Type: GrantFiled: April 26, 2019Date of Patent: May 17, 2022Assignee: ARVOS Ljungstrom LLCInventor: Jeffrey O'Boyle

Patent number: 11137217Abstract: A rotor for a high temperature rotary pre-heater includes a hub that has an exterior surface thereon. The rotor includes an annular rim positioned around and coaxially with the hub. The annular rim has an interior surface. A plurality of partitions extend between the hub and the annular rim. Each of the partitions is located in a predetermined circumferential position by one or more alignment features. The exterior surface, the interior surface and/or the partitions have one or more of the alignment features thereon.Type: GrantFiled: April 5, 2017Date of Patent: October 5, 2021Assignee: Arvos Ljungstrom LLCInventor: Jeffrey O'Boyle

Patent number: 10704840Abstract: A seal assembly includes a first leaf with a spacer secured proximate a distal end of the first leaf. The spacer extends along the first leaf from an outboard end of the spacer to an inboard end thereof. The seal assembly includes a second leaf that is secured to the spacer so that the distal end is positioned proximate the outboard end of the spacer. The second leaf has an elongate section that extends away from the distal end. The elongate section extends beyond the inboard end of the spacer and terminates along the first bend of the first leaf, so that a portion of the second leaf proximate the terminus of the second leaf is slidingly moveable relative to and in compressive engagement with a portion of the first bend, and a portion of the second elongate section is spaced apart from the first elongate section.Type: GrantFiled: February 10, 2017Date of Patent: July 7, 2020Assignee: ARVOS LJUNGSTROM LLCInventor: Jeffrey O'Boyle
