Abstract

1,203,767. Fluid resistances. SIEBE GORMAN & CO. Ltd. Sept.26, 1967 [Sept.30, 1966], No.43895/66. Heading G3H. [Also in Division F2] A fluid resistance incorporated in a valve (See Group F2) feeding a closed circuit breathing apparatus, comprises a tube 2 wound around a bobbin 3 and communicating at 5 with chambers 6 provided with porous filter plugs 7 of sintered bronze or ceramic. The tube is between one and twenty feet in length and between 0À002 and 0À015 inches in diameter, and is either incapsulated in synthetic plastic 4 or soldered into a metal can.
