<p>922,322. Detecting water in fuel. BENDIX CORPORATION. May 17, 1961 [June 27, 1960], No. 17937/61. Class 97 (3). Aircraft fuel is passed through a unit containing one or more fuse assemblies 22 comprising a series of elements 34 which provide pores enabling the fuel to flow therethrough when it contains extremely fine solid contaminants and/ or water below a predetermined concentration but which expands when the water contamination is above the predetermined level to block the pores and prevent passage of the fuel. Each assembly 22 may be in the form of a tube 32 formed of alternate layers of smooth-surfaced and rough-surfaced washer-like elements 34 impregnated with an epoxy resin solution and cured for 30 minutes at 350‹ F., the tube 32 being compressed by a spring 40 within a perforated outer tube 38. A number of such assemblies 22 may be mounted by means of their ferrules 44 and sealing rings 46 on an apertured plate in a unit so that the fuel flows through the assemblies in parallel. In a modification each tube 22 is formed by winding ribbon-like material edgewise to form a cylindrical member. Specification 648,466 is referred to.</p> |
