848,775. Filters. PERMANENT FILTER CORPORATION. Dec. 23, 1958 [May 14, 1958], No. 41440/58. Class 46. Liquid (e.g. fuel) to be filtered and to be freed from water is pumped at 70 into a tank 40, Fig. 5, and first passes in parallel through a number of hollow socks 60 of woven synthetic fabric (e.g. nylon) each having a tufted interior. Here, some water and solids are retained, and the electrostatic charge on water droplets passing through is enhanced. Passing into member 65 and down conduit 66, the mixture next rises in parallel inside a number of closedended filter members 12, Fig. 7, of sintered bronze or stainless steel spheres or of fine wire non-ferrous screen, further solids being retained, and the electrostatic charge on the water droplets being neutralised. The mixture next passes through three layers 25À27 of fibre glass, where more solids are retained and the water droplets are increased in size, and finally through an optional strip of glass cloth 95. Fuel rises to an outlet 44, Fig. 5, whilst water settles on to a partition 75 and flows out at 45. Outlet 100 is for any matter which settles to the bottom of the tank.
