Abstract

253,606. Cleworth & Co., Ltd., A. B., and Cleworth, A. B. March 19, 1925. Filtering.-An air or gas filter is composed of juxtaposed sheets of expanded metal, successive sheets having the long diagonals of their cells parallel, and the front surfaces of the strips forming the cells sloping to the left and right respectively; the centres of the corresponding cells of the successive plates are in staggered relation. Their appearance is shown in Figs. 2 and 3. A second series of expanded metal sheets having the long diagonals of the cells alternatively at right-angles, as in Fig. 4, may be combined with the first series, the whole being contained in a frame, and the plates smeared with oil &c.
