Abstract: A shaft seal assembly is configured for sealing, for example, a reciprocating axial-movement shaft. The shaft seal assembly includes an annular elastomeric seal body having at least one first sealing surface configured to sealing engage a shaft. A lubricant reservoir body includes a second sealing surface and comprises a polymer matrix having a porous structure containing micro-pores, wherein the micro-pores are filled with lubricating oil.

Abstract: System and method for implementing a forward compatibility syntax in a directory services environment is described. In one embodiment, data comprising an attribute according to a new syntax that is supported by newer servers, but not by older servers, is separated into data with respect to which referential integrity is not a concern (hereinafter “blob data”) and data with respect to which referential integrity is a concern (hereinafter Distinguished Names (“DNs”)). The two types of data are then combined according to a forward compatibility (“FC”) syntax that is supported by both older and newer servers. Only certain, newer, servers understand and convert between the FC syntax and the actual new syntax; older servers are capable of supporting the FC syntax without needing to understand it.
