Method of Making a Marine Gas Turbine Filter
First Claim
1. A method for making a pocket filter assembly comprising:
- extruding a length of header element material having a pair of longitudinally extending side walls, a longitudinally extending cross-member extending between and substantially normal with said side walls, and a longitudinally extending bottom wall joining lower edges of said side walls below and substantially parallel with said cross-member;
miter cutting at approximately 45°
said length of header element material into header ends and header sides;
inserting one end of an “
L”
shaped clip into a cavity in each end of said header ends or said header sides, said cavity being defined by said side walls, said bottom wall, and said cross-member;
inserting the other end of said “
L”
shaped clip into the other of said header ends or said header sides to form a rectangular header having a continuous channel about a downstream side, said channel defined by said cross-member and said side walls;
inserting an upstream perimeter portion of a filter element into said channel, said filter element having a plurality of pockets;
placing a liquid polymeric material into said channel; and
solidifying said liquid polymeric material forming a header frame having said upstream perimeter portion of said filter element unitary therewith.

Abstract
A method for making a pocket filter assembly is provided. Two side and two end header elements each having a pair of longitudinally extending side walls and a longitudinally extending bottom wall forming a longitudinally extending channel are joined at ends forming a rectangular header with two opposing sides and two opposing ends. The bottom wall and side walls of each of the opposing sides and the bottom walls and said side walls of each of said opposing ends become adjacent forming a rectangular header with a continuous bottom wall and continuous inner and outer side wall having a continuous channel therein. An upstream perimeter portion of a pocket filter element is inserted in the continuous channel and a liquid polymeric material is placed therein. The polymeric material is solidified forming a header frame having the upstream perimeter portion of the filter element unitary therewith.
