Abstract

540,215. Filtering gases. CHEMA MANUFACTURING CO., Ltd., and SIGMUND, M. March 5, 1940, No. 4135. [Class 8 (ii)] A filter element comprises layers or convolutions 1 . . . 5 of paper or fabric forming a series of isolated chambers each chamber being supported internally by a spacing strip 8 corrugated in the direction of fluid flow. The corrugated strips may extend the length of the filter and be supported at intervals by adhesive tape, or a series of corrugated strips spaced apart longitudinally may be used. Two corrugated strips may be placed back to back with an adhesive strip between, as an insertion. The filter shown is formed by providing transverse cardboard spacing strips 6 on a strip of paper &c. afterwards wound into a spiral. Alternate ends of the annular filter spaces, and one end of the central space are closed by plastic or other impervious material. Specification 539,269 is referred to.
