Abstract: 849,821. Making filters ; filter media. CONNECTICUT FILTER CORPORATION. Nov. 30, 1956, No. 36743/56. Class 46. [Also in Groups V, VIII and XXVIII] A method of moulding filters comprises mechanically separating vegetable fibre pulp into its fibrous constituents in a liquid consisting of alcohol or acetone and not more than 30% water and causing the liquid carrying the pulp to flow by suction through a perforated mould to deposit the fibres on the mould and form the filter. The vegetable fibre may be wood, cotton, flax, hemp or sizal and the alcohol may be isopropyl, methyl, ethyl or tertiary butyl and the filters may be impregnated with phenolic resins, other resins, plastics or waxes. The apparatus comprises a shredder 15, pulper 16, supply tank 22, measuring tank 24, mould 30, a pump 70 to supply liquid to the mould 30, tank 22 and pulper 16 and vacuum tanks 52 and pump 57 connected to the mould 30 by a pipe 53. In operation, the mould cavities are filled with liquid by the pump 70 and the vacuum tanks 52 evacuated by the pump 57. The pulp is fed to the shredder 15 until sufficient is deposited in the pulper 16 where it is mixed with the liquid and transferred to the pulper 22 where it is continuously agitated and mixed with further liquid before passing to the measuring tank 24. The measured quanity of pulp is then passed to the mould 30, the mould 30 is connected to the tanks 52 to draw off the liquid and the pulp forms the filter on the perforated base 43 of the mould. Sizing elements 46 may be lowered into the mould to size and compress the pulp. The resultant filter may have layers of different density and may be dried in an oven 76 with phenolic resins, other resins, plastics or waxes. Fig. 10 shows a filter 80 having a density increasing from the periphery inwards. Fig. 11 shows a filter 80 contained in perforated outer and inner sleeves 120, 123 with solid ends 120 wherein the inner sleeve 123 may be covered with at least one layer of cloth.
