    Abstract: 1,199,005. Making filter elements. BENDIX CORP. 8 Aug., 1967 [17 Aug., 1966], No. 36377/67. Heading B1D. A tubular element, for coalescing water from fuel or filtering solids from liquid, is made by rolling a batt 18 of glass fibre spirally, incorporating in the end faces strips 56 of thermoplastic and bonding the roled 'batt to thermoplastac end caps (Fig. 1, not shown) by 'spin welding', in which strips and caps are melted by friction therebetween and then held together. The caps bond to both the strips 56 and the glass fibre. In Fig. 4, strips 56 are folded round the edges of a glass fibre screen 50 which is then rolled to form the outer layer of the roll. Alternatively an extruded strip of U-section (Fig. 6, not shown) or a single strip heat-bonded to screen 50 may be used. If no screen 50 is used (Figs. 1 to 3, not shown), the thermoplastic strips (22) may be laid along the edges of batt 18 before rolling and themselves extend several times round the element. Additional porous supports may be included inside and outside the roll.

    Abstract: 926,445. Filters and coalescers; gravityseparation apparatus. BENDIX CORPORATION. July 21, 1961 [Aug. 25, 1960], No. 26542/61. Class 46. Fuel contaminated with water and solids is introduced at 11, Fig. 1, and passes first through coalescer elements 14 consisting e.g. of resin-bonded compressed layers of glass fibres and then through filter-separat- or elements 18. Each element 18, Fig. 2, consists of a resinimpregnated pleated paper cylinder 24 surrounding a porous tubular member 26 which has the property of stopping the liquid flow when either sufficient water has passed through cylinder 24 to cause the member to swell and thereby to close the pores through itself, or sufficient solids have passed through cylinder 24 to build up a residue layer which obturates the pores. The member 26 may consist of a stack of discs of paper, cellulose or other fibrous or non-fibrous material, treated with an epoxy resin solution. A pressure-gauge 44 may be provided. Specification 922,322 is referred to.
