Abstract

808,154. Gas filters. GENERAL MOTORS Ltd. Aug. 19, 1957 [Sept. 16, 1957], No. 27316/56. Class 8(2). [Also in Group I] A gas filter element of the spirally coiled paper type is formed by providing on one side of a single strip of porous paper 2, Fig. 1, a patch of adhesive 4 at one end 3 thereof and of length equal to about 1¢ times the circumference of the first and inner turn of the coil when formed and a continuous line 5 of adhesive running first along one edge of the strip then laterally to or near the other edge, along that edge then laterally to the first edge and so on and of such depth as to provide spacing of adjacent convolutions which form pockets 7, Fig. 3, alternately sealed and open at one end of the coil and conversely are respectively open and sealed at or near the other end according to the lateral spacing of the longitundinal portions of the line of adhesive ; the transverse portions of said line being in radial register. Corrugations or dimples 8 assist in the spacing of adjacent convolutions. The element so formed has an impervious inner core 6 formed by the patch of adhesive and is mounted within a casing 14 having a lateral dust-laden gas inlet and a central clean gas outlet. In a modification the strip of filter paper has a central longitudinally extending series of perforations 10, Fig. 4 (not shown), along each side of which extends from a patch of adhesive at one end a continous line of adhesive having a configuration similar to that shown in Fig. 1.
