Abstract

667,933. Filters. RANE, L. May 31, 1950 [June 11, 1949], No. 13618/50. Class 46 A filter, for example for incorporating in a bloodtransfusion apparatus, comprises a casing 10 provided with a drip nozzle 34, a series of filter elements 50 separated by washers 52, and with a transparent sighting tube 40 for observing the rate of drip. The parts 12 and 14 forming the part 10 have a washer 18 interposed between them and may have milled outer surfaces at the regions of largest diameter. The elements 50 are of fine wire net or of nylon textile fabric or of foraminous discs of nylon or hard rubber. An upper tubular extension 24 receives the end of a flexible tube (not shown) while the lower end of the sighting tube 40 may be provided with a reduced extension to receive a further flexible tube.
