Abstract: 1,239,378. Dispensing liquids under gaseous pressure. AEROSOL INVENTIONS & DEVELOPMENT S.A. May 22, 1969 [June 14, 1968], No.26053/69. Heading F1R. A dispensing valve of the type described in Specification 59311/68 has two dispensing positions: one in which the fluid is dispersed from only one container; the other in which a mixture of fluids is dispersed from both containers. In the embodiment of Fig. 2 (not shown) a spool 14 can be moved against the action of spring 11 to a first dispensing position in which the passage 16 is uncovered. Fluid in container 2 is forced up dip tube 17 into main bore 7 and then via side passage 13 into a tubular portion of stem 5, where it is subsequently discharged through nozzle 20. When the spool is fully depressed in a second dispensing position it is below the upper part of groove 18 in the extensive bore 15, thus liquid in collapsible bag 22 can be forced up to main bore 7 where it is mixed with the other liquids and subsequently dispensed. Other embodiments are described: in which the groove 18 is diametrically opposite to the opening of the passage 16 Fig. 2 (not shown); and in which the spool 14 covers the passage 16 Fig. 3 in the first dispensing position.

Abstract: 1302036 Gas turbine engines - cooling ROLLS ROYCE Ltd 7 May 1970 [26 June 1969] 32368/69 Heading F1G A gas turbine comprises a rotor, a row of equiangularly spaced apart rotor blades secured to the rotor and first cooling fluid supply means adapted to direct cooling fluid at the leading edge of each rotor blade so as to form on each rotor blade a layer of the cooling fluid which extends over at least a major proportion of the surface of the rotor blade. The gas turbine engine shown in Fig.1 comprises compressor 12, combustion equipment 14, turbine 16 which drives the compressor and a separate power turbine 18. Air from the compressor passes to chambers 22 each of which contains a flame-tube 27, combustion gases being directed by the guide vanes 36 on to the turbine rotor blades 45 and being redirected by inter-stage guide blades 60 on to further rotor blades 45. The turbine rotor comprises discs 42 with flanges 46, 48. Air from the chamber 22 is directed by guide vanes 26 and by bores 52 in the rotor on to the external surfaces of the rotor blades 45 for cooling thereof. Some air also passes through bores 50, 55 so as to provide a layer of cool air adjacent the surface of the rotor between the rotor blades. The further stage of turbine rotor blades may be similarly cooled. Some air from the chamber 22 also passes through ducts 41 and 64 to form a layer of cooling air over the external surfaces of the inlet nozzle guide vanes 36 and the inter-stage guide vanes 60, also into the inter-stage guide vanes 60. A heat exchange device is provided comprising a coil 70 disposed in the exhaust duct, the coil containing liquid metal which is transferred through duct 72 by pump 74 to a coil 24 disposed in the chamber 22 whereby the air in chamber 22 is pre-heated. The liquid metal then passes through a second coil 68 disposed in each inter-stage guide vane 60 whereby the vane is cooled. In a second embodiment pure water is passed through a coil 70b disposed in the exhaust duct, the steam generated being utilized as cooling fluid in place of air as in the first embodiment. The steam passes through the inlet nozzle guide vanes 36b into a chamber 25b which is separated from the chamber 22b by a partition 80, the steam then passing through bores 52b, 50b for cooling of the first stage rotor blades 45b, also through ducts 64b, 62b for cooling of the inter-stage guide vanes 60b.

Abstract: 1311082 Passenger transport systems; seat arrangements NATIONAL RESEARCH DEVELOPMENT CORP 25 March 1970 [26 March 1969] 15796/69 Headings B7J and B7L A transport apparatus comprises a plurality of oblong conveyer elements in the form of flat wooden boards 11 assembled in a row side-byside so that the long sides 12, 13 of adjacent elements 11 slide against one another by means of rollers 24 rolling against catch strips 28 and the surfaces of the row of elements 11 form a pavement. A drive mechanism allows the pavement to be driven along rails 20 which define paths 32, 33, by way of castors 17, 18 carrying bogies 19. The direction of motion is normal to the long sides 12, 13 of elements 11 and sliding contact of sides 12, 13 allows the pavement to follow paths lying up to a certain angle to the normal. The rails 20 rest upon sleepers 21 and the essential parts of the drive system are represented by male and female members 22, 23 respectively. The member 22 may represent a driven variable-pitch screw mounted on the sleeper 21 and the member 23 may represent a co-operating nut fitted to each element 11. Alternatively, 23 may be a " stator " portion of an electric motor and 22 one of a series of rotor portions. At least some of the elements 11 have at least one side of circular arcuate shape, in which curved side engagement between adjacent elements is between a convex side on one of them and a concave one of equal radius on the other, and in which adjacent platforms, by sliding their adjacent curved faces against each other, may substantially change their inclination to the path and thus the effective width and speed of the moving pavement. In the apparatus described with reference to Fig. 4, the elements 11 are of similar shape and arrows 34 indicate the direction of travel, while 35 is a stationary platform upon which passengers from a high speed portion of the pavement may alight at arrow 36 or where they may board the high speed pavement at arrow 37. The width of the pavement is inversely related to its speed of travel at that point, so that, over regions 38 and 39, the pavement is moving fast, while between these regions, it slows down to a minimum speed over region 40 where passengers alight and board at the inside edge 41. In an embodiment described with reference to Fig. 13, each element 11 has a wall 59 mounted along its side 15 and a shorter wall 60 extends a short way down side 13. A seat 61 is mounted at the wider end of each element 11 so that the walls 59, 60 form the back and side arm of seat 61.
