Abstract

535,153. Filters. CHEMA MANUFACTURING CO.. Ltd., and SIGMUND, M. Jan. 31, 1940, No. 1924. [Class 8 (ii)] A filter element is formed by winding spirally strips 1, 2, of filter paper or fabric with narrow spacing strips 3, 4, 5, 6, arranged as shown in Fig. 1, the strips 4, 5, being of relatively thick, stiff and impervious material such as cardboard and the strips 3, 6 being of corrugated material such as paper. Adhesive is applied to the faces of the strips 4, 5, and, if necessary, to the ridges of the strips 3, 6. The element is completed by an impervious disc 7, Fig. 3, closing the central space at one end, and an impervious flange 8 encircling the periphery at the other end and fitting in a container in which the element is used. Fluid supplied to the upper end of the container flows past corrugated spacers 3 into alternate spaces, filters through the strips 1, 2 into the adjacent spaces, passes the spaces 6 to the lower portion and then filters again to the spaces below the spacer 4 and leaves at the lower end. The strips 5 may be inset from the edges of the filter strips to form channels to receive layers of bitumen and latex, which serve as a seal. The elements are stated to be applicable in respirators for personal use and in the air treatment plant of gas shelters.
