A gas turbine air intake system uses a filter element having a seal member with radial projections and radial recesses. The seal member forms a seal with components on the tube sheet of the system and at the end opposite of the tube sheet. At the end opposite of the tube sheet, there can be an assembly cover, or alternatively, an additional filter cartridge.

A microporous membrane for flash distillation comprising at least three layers having distinct properties is disclosed. Generally, the membranes contain outer layers of relatively small pore size, with an interior layer with relatively large pore size. The invention is also directed to a system for desalinization comprising a source of hot brine.

Microporous membrane for flash distillation

An adsorbent filter including compression molded particulate adsorbent construction is provided. The compression molded particulate adsorbent construction contains a particulate adsorbent and a sufficient amount of binder to retain the particulate adsorbent in a non-free flowing form. The adsorbent filter preferably includes a compression molded particulate adsorbent construction as described, positioned within an outer, porous cover. Preferably the outer, porous cover includes expanded porous polytetrafluoroethylene. In certain preferred applications, the adsorbent filter is positioned within a housing defining an internal volume and including therein electronic component(s), such that the adsorbent filter protects the internal volume of the housing, and components therein, from damage. The typical application is as a disk drive adsorbent filter. A preferred method for preparing an adsorbent filter according to the present invention is provided.
