[Also in Division B1] A respirator in which exhaled gases are recirculated] for inhalation after removal from them of CO 2  comprises a chamber 14 arranged for receiving exhaled gas and having a permeable non-porous wall 17 having a greater permeability to CO 2  than O 2 , a pump 23 for circulating air over the outside of the permeable wall to prevent build-up of CO 2  adjacent its outside surface and a conduit 28 for recirculating gases from the chamber 14 to the respirator gas supply conduits where it is augumented with oxygen from a container 31 or first cells operated in reverse, or air from a compressor (43 Figure 2). Desirably the gas supplied for inhalation contains about 50% oxygen by volume. The chamber 14 and a chamber through which air is circulated by the pump 23 are separated by the permeable wall 17 and provided in a rebreather unit 16. The wall is a thin film of dimethylsilicone rubber or a cellulose ester, e.g. cellulose acetate which may be impregnated with caesium bicarbonate and permit the removal of water vapour as well as CO 2 . The film is supported against rupture and albrasion by open-mesh cloths (19, 20 Fig. 3) on each side and a more rigid mesh screen (21). Nitrogen passes through the permeable wall into the respiratory system from the air circulated by the compressor 23. Undesirable, build-up of nitrogen within the system is prevented by the provision of a bleed. Gas flairing from tihe chamber 14 is returned to the gas supply conduit of the system through a breathing bag 29 and is mixed with supplementary oxygen from the container 31. Alternatively, the respiratory system may include two similar gas separators (44, 46, Fig. 2) each having an oxygen permeable membrane (48, 53). One (44) of the separators is supplied with atmospheric air from a compressor (43), and its output air, containing a higher proportion of oxygen than atmospheric air, is mixed with gases from the rebreather unit (42) and supplied by a second compressor (51) to the second gas separator (46) the output of which is connected through a demand regulator (57) to a mask (59). The rebreather unit may comprise several chambers in parallel each with a permeable wall area.

Abstract: 1,052,385. Steam generators. COMBUSTION ENGINEERING Inc. Nov. 12, 1963 [Nov. 20, 1962], No. 44585/63. Heading F4A. In a method of starting a forced flow once through vapour generator in which initially fluid is recirculated through the vapour generating section and a primary superheater, pressure and temperature conditions at the outlet of the primary superheater are accurately measured in a section of the recirculation circuit and the flow to a finishing superheater commenced and controlled in accordance with said conditions to ensure that all the fluid flashes to vapour before entering the finishing superheater. The vapour generator heated by combustion gases consists of a feed pump 12, Fig. 1 (not shown), supplying fluid from a deaerator 14 through a preheater 18 and an economizer 22 to a vapour generating section 24 and primary and finishing superheaters 26, 28 from which vapour passes through a turbine 30 to a condenser 32 with a shut-off valve 55 and a throttling valve 56 arranged in parallel to control the flow between the superheaters 26 and 28. The starting method consists of closing valves 55, 56 opening boiler extraction valves 51, 52 in an extraction line 50 to the condenser, supplying vapour from an auxiliary source 38 to the deaerator 14 and circulating fluid through section 24 and superheater 26 whilst the generator is being fired until the clean-up operation is completed. A feed valve 20 is then closed and with valve 51 set to open only at a given relief pressure, fluid is recirculated by pump 48 through section 24 via conduit 44 and through the superheater 26 via conduit 60. At the same time the turbine is heated and rolled by vapour from the source 38 which first cools the superheater 28. The flow through conduit 60 allows the temperature and pressure before valves 55, 56 to be accurately measured. When conditions ensure the complete flashing to vapour of the fluid, the control element 68 commences to open valve 56, feed valve 20 is opened to pass an equivalent flow to section 24 and the auxiliary vapour flow is reduced by closing valve 42. This continues until the pressure drop across valve 56 becomes negligible when valve 55 is opened and valve 42 closed to establish normal operating conditions. In another embodiment, Fig. 2 (not shown). auxiliary vapour is not used, vapour for cooling superheater 28 and starting turbine 30 being produced by flashing liquid leaving superheater 26 through valve 56.
