    Abstract: 815,959. Gas filters. BENDIX AVIATION CORPORATION. Oct. 24, 1957 [Dec. 6, 1956], No. 33283/57. Class 8(2). [Also in Group I] A tubular gas filter member 12 which may be of paper and having longitudinally extending radial pleats is supported externally by a wrapper 14 of perforated material e.g. metal, the perforations having their edges 20 spaced away from the outer face 22 of the wrapper 14 and from the sides of the pleated member and the ends of the filter member 12 and wrapper 14 being embedded in plastic end caps 16, 18. As shown the perforations are punched outwardly of the wrapper to form rounded edges 24 adjacent the member 12 and the ends 26 of the wrapper are bent inwardly to support the ends of the pleats during the formation of the plastic end caps. The edges 20 may be turned inwardly to provide a smoother outer surface of the wrapper. Specification 770,556 is referred to.

    Abstract: 795,290. Filters. BENDIX AVIATION CORPORATION. March 13, 1956 [May 26, 1955], No. 7851/56. Class 46. [Also in Group XXVIII] A filter and demulsifying device suitable for removing water from petrol comprises a pleated resin-impregnated inward flow paper filter sleeve 54 surrounding a single helically wound layer 52 or a plurality of layers of nylon fibres bonded at their points of contact with a thermosetting resin and supported by a perforated metal core member 51; the ends of the tube so formed being sealed by plates 56, 58 and enclosed in a casing 40 having an inlet 48 and a filtered liquid outlet 47. A second casing 44 having an outlet 50 surrounds the casing 40 and encloses a plurality of filter elements 46 of the edge or pleated type. The layers of nylon are prepared by splitting a sheet of fibrous nylon material edgewise to form a mat having one side more loosely packed than the other.
