Abstract

710,621. Filters. BOSCH GES., R. Sept. 4, 1952 [Oct. 4, 1951], No. 22230/52. Class 46 Filter and/or flow control discs of the kind exemplified by Specification 710,832 are formed as connected parts of a strip which has cut-away portions along its length and which is folded in zig-zag formation to form a filter pack. Figs. 3 and 4 show a strip after cutting, and after cutting and folding, respectively, corresponding to the embodiment of Fig. 2 of Specification 710,832. Figs. 1 and 6 (not shown) correspond to Figs. 1 and 3 of that Specification. A further form is shown in Fig. 5.
