Abstract: A mechanical seal face has a significant increase in the ability of the seal to tolerate poor lubrication conditions such as dry running. The mechanical seal employs a thin, non-corrugated flat sheet of flexible thermally conductive graphite material placed between one of the mechanical seal faces and a metal surface such as a metal surface defined by a shaft sleeve or gland serving as a seal ring holder. The graphite sheet is located axially between a back face of the more thermally conductive mechanical seal ring and the metal face holder part. The conductive seal face material preferably is a ceramic or cermet material such as silicon carbide, tungsten carbide, silicon nitride, aluminum oxide, or a metallic material such as stainless steel.

Abstract: A partition system for subdividing a building space includes a partition frame including a top frame member and intermediate frame members, cover panels releasably attached to the partition frame to cover the partition frame, and a floor channel including an upwardly facing channel for supporting the partition frame. An upper trim system includes a top cap configured to engage and cover the top frame member, and further includes an end cap configured to engage and cover an end of the intermediate frame members, and still further includes a corner piece for aesthetically interconnecting the top cap and the end cap. A lower trim system includes an elongated base trim side piece attached to the floor channel for covering a lower portion of the partition frame, and further includes a base trim end shoe attached to the partition frame for covering an end of the frame along the building floor.
