Abstract

916,050. Fluid - impervious diaphragms. HILLMAN Ltd., J. & A., and HILLMAN, J. L. April 13, 1961 [June 14, 1960], No. 20897/60. Class 140. A fluid impervious diaphragm is produced by stretching a knitted nylon fabric about a rigid non-absorbent former, forming on the exposed surface of the fabric a coating of desired thickness by applying thereto a solution containing a polymer based synthetic rubber blend, and thereafter vulcanizing the coating and removing the coated fabric from the former. The polymer may be a gas-resistant polymer such as chlorosulphonated polyethylene. The coating may consist of a plurality of superimposed coats each of which is dried to remove solvent before the application thereto of the succeeding coat. The former may be made of glass or porcelain. The blend may also contain polyethylene, and the gas impermeable polymer may be replaced by an oil impermeable polymer to produce an oil impermeable diaphragm. The coating may be applied by dipping, spraying or brushing the blend on to the fabric 1 stretched about former 3, secured in a taut condition by band 4. After the coating 2 has been vulcanized, the fabric is removed from the former and trimmed along line 6.
