<p>1276525 Filtering cartridges / apparatus ECODYNE CORP 18 Aug 1969 [30 Aug 1968] 41144/69 Heading BID In filtering apparatus otherwise as described in Specification 1276524 each cylindrical cartridge has an internal float 47 which rises with the liquid level during reverse flow cleaning and prevents reverse flow air from passing directly to the parts of the cartridge above the liquid level. The distribution of air and liquid to different cartridges and to different parts of one cartridge is thus evened out. During filtering the float remains at the top of the cartridge and during draining it rests on a cross-bar (53) which prevents it closing the lower end of the cartridge. Fig. 5 (not shown) illustrates a barrel-shaped float.</p> |
