Abstract: 1,251,312. Driving helicopter rotors. UNITED AIRCRAFT CORP. 6 Feb., 1970 [27 Feb., 1969], No. 5710/70. Heading B7G. [Also in Division F1] The invention relates to a gas turbine engine which comprises a gas turbine type gas generator and two power turbines in series flow, there being means for causing gases from the gas generator to flow through one or other of the power turbines or through both. The invention is shown applied to a gas turbine engine of the ducted fan type, the engine also driving an output shaft which may be connected to drive a helicopter lift rotor. The engine comprises a compressor 6, combustion equipment and a turbine 4 which drives the compressor, this constituting a gas generator section; a first power turbine 12 mounted on shaft 10 which extends through the gas generator and has a fan 8 mounted at its forward end; and a second power turbine 16 which is mounted on a shaft 70 and drives an output shaft 18 through gearing 100, 102, the shaft 18 driving a helicopter lift rotor. Air from the fan blades 9 is divided by a flow splitter 32, a first portion B flowing to the compressor 6 and a second portion C flowing through fan duct 42 which is defined by a fan casing 30, this air discharging through propulsion nozzle D. The power turbines are disposed in a duct 26 through which gases E from the gas generator flow, a shroud ring 50 being disposed around the blades 24 of the turbine 12 to define two flow paths, one through the blades 24 and the other 56 being a by-pass duct around the turbine. Adjustable vanes 58 are disposed in the by-pass passage 56 so that gas flow through the blades of the turbine 12 may be varied between zero and full flow. A similar shroud 80 is disposed around the blades 78 of the second power turbine 16 to provide a by-pass passage 86 in which adjustable vanes 88 are disposed so that gas flow through the turbine 16 may also be varied between zero and full flow. Thus, the ducted fan 8 only may be driven or the lift rotor only or both the ducted fan and lift rotor be driven. In a second embodiment the first may power turbine 12 drives the shaft 10 as before, but the forward end of the shaft 10 is connected to a shaft 18a which in turn is connected to drive a lift rotor. The second power turbine 16 is mounted on a shaft 70 as before, but drives fan blades 8a which are mounted directly on the third stage blades 78 of the turbine 16. The blades 8a are disposed in a fan duct 112 which is defined outwardly by a fan casing 30a. An opening 100 is formed through the wall of the gas flow duct 26a downstream of the turbine 12 and by-pass passage 56, the opening being controlled by an axially-movable cylindrical valve 124. Thus gas flow through the second power turbine 16 may be controlled between zero and full flow. When the valve 124 is open gases flow through the opening 100 through valve opening 122 into chamber 120 thence through hollow struts 126 which extend across the fan duct 112, and discharge through openings 131 in the fan casing 30a.

Abstract: 1290001 Evaporators; concentration of solutions IONICS Inc 1 Dec 1969 [24 Dec 1968] 58575/69 Headings BIB and B1X A volatile component is removed from a liquid mixture by diffusion of vapour therefrom through selective membranes 10 in an apparatus comprising a pack of feed compartments 8, heating compartments 7 and vapour compartments 9 formed by frame members and heat transfer sheets 11, the arrangement being such that two liquid flow compartments are disposed on either side of each vapour compartment, and conduits formed by aligned holes in the membranes, sheets and the gaskets of the frame members supply the feed stream 60, the heating medium (steam or hot water) 62 to their respective compartments while a third conduit 61 serves for applying partial vacuum to the vapour compartments by pumps 26. The liquid enters and leaves the compartments 8 via channels 50..56. The liquid leaves each compartment 8 in a direction away from the immediately adjacent selective membrane 10. In the apparatus shown, feed liquid and heating medium are pumped through tubes 20 and 21 respectively into vacuum spacers 14. These streams then flow in parallel through their respective compartments 8 and 7. The concentrated liquid is withdrawn from the apparatus through tubes 23; and heating medium is withdrawn through tubes 24. In a modified apparatus (Fig. 1, not shown), the feed liquid flows in series through the compartments 8. It is stated that, instead of applying partial vacuum to compartments 9, sweep gas may be passed through them. The apparatus may be used for the concentration of aqueous extracts of coffee, and fruit and vegetable juices. For such aqueous liquors, the membrane-material should be strongly hydrophilic to allow permeation of water and impede the evaporation of organic constituents. The membrane may be made of an organic polymer or a cellulose ester.
