  • Publication number: 20020155225
    Abstract: A method for producing charge-modified polyester comprising treating the polyester with at least one agent sufficient to cause hydrolysis of the polyester and a charge-modifier having one or more epoxy groups with a fixed formal charge, resulting in the formation of a bond between the one or more epoxy groups and the polyester. The polyester may be treated with the agent, which is presently preferred to be an alkaline, amine, or combination of both, and charge-modifier, which could have a positive or negative charge.

  • Patent number: 5399264
    Abstract: A compressible differential pressure energized seal (18) coacting between a filter element (10) and the like and a housing (21) comprises a compressible portion (35) having a large open end (36) and a small open end (37), the large end (36) directed toward and contacting the housing (21 ) and the small end (37) directed toward the filter (10) element; and an annular flange (38) integrally attached to the compressible portion (35) at its small end (37) and extending outwardly, the flange (38) operatively communicating with the filter element (10). The seal (18) may also include at least one flap (43) to center the filter element (10) to which it is attached onto a centering rod (31 ) carried within the housing (21 ). Such a seal (18) is compressed when the element (10) is operationally enclosed within the housing (21 ) to provide a leak-proof seal during operation and is self-energizing during operation such that as the differential pressure increases, it more forcefully engages the sealing surface.
