Abstract: A turbomachine seal plate includes a substrate with a first material that defines a surface having a substrate width. The substrate includes a first terminus extension that is raised and extends from a terminus portion of the substrate. The first terminus extension extends outwardly relative to the surface up to a terminus extension height. The turbomachine seal plate also includes a coating having a second material that covers the surface of the substrate and defines a coating width. The coating abuts a side of the first terminus extension. The coating width can be substantially equal to the terminus extension height.

Abstract: Embodiments of the invention provide a vacuum system including a housing and at least one filter disposed within the housing. A valve assembly can be at least partially disposed within the housing and can be in fluid communication with the filter. The valve assembly can include a manifold and a support member coupled to a plurality of dampers. The plurality of dampers can include a first damper and a second damper that include unequal sizes. The support member and the dampers can be configured and arranged to move between a first position and a second position.
