Abstract: 848,912. Gas turbines. COLVIN, R. H. Dec. 19, 1956 [Dec. 22, 1955], No. 38682/56. Class 110 (3). A gas turbine jet-propulsion engine comprises a compressor supplying air to a combustion chamber which discharges through a restricted outlet into a duct in which air is caused to flow by the jet so as to drive a turbine, located upstream of the combustion chamber outlet, arranged to drive the compressor. The jet propulsion engine shown comprises a tubular casing 10 spaced from inner casing 11 by struts 12, 13 to form an annular air duct leading from an inlet diffuser 14 to a rear duct 15. A conical guide member 16 forms with the portion 17 of the casing 11 a combustion chamber 18 which is supplied with compressed air by a centrifugal compressor 21 which may, if desired, be a multi-stage compressor. The outlet of the combustion chamber 18 is defined by a Venturi-shaped restriction 27 in casing 11 which co-operates with an axially-adjustable plug 28 to control the pressure in the combustion chamber. The plug 28 has threads 30 which engage corresponding threads in a cylindrical casing 53 and is rotated from a control-shaft 59 through gearing 58, 60 and splined rod 55. The combustion-chamber may have a deformable discharge outlet for varying the outlet area instead of the plug 28. The plug 28 may be cooled by air passing through ports 31 into the interior of the plug 28. Cooling fins 27a may also be provided. The combustion gases from the outlet 51 caused an air flow to be induced in the passages between the casings 10, 11. This air flow is used to drive a turbine 47 provided with adjustable stator blades 48. This turbine drives the compressor 21 through multiplying gear 35, 36, 38, 39. A starting- motor is connected to the shaft 34 by an overrunning clutch 50. Reference has been directed by the Comptroller to Specification 800,261.

Title: Process for the manufacture of sheets of polyvinyl chloride which are permeable to air and impermeable to water, and products thus obtained
IPC: C08J9/28
Filed: 1966-08-31
Abstract: Air-permeable, water-impermeable polyvinyl chloride sheets are prepared by introduction of water into a plastisol of polyvinyl chloride and subsequent evaporation of the water during gelling, the water being first emulsified in a plasticizer of the plastisol and then dispersed in the plastisol, which is then spread out in a thin layer and gelled by heating, preferably at a temperature above the vaporization point of water.  The preferred proportion of water in the final mixture is between 10 and 12% by weight. Before the emulsion is formed various additives may be added, e.g. emulsions of plasticized or non-plasticized vinyl acetate, methyl methacrylate, styrene, butadienes, polyethylene or silicones. The plastisol can also contain inert charges, colouring agents, thickeners and fluidizers.

Title: Improvements in Mounting Plastic Sheet Material as a Wall Covering or False Ceiling.
Inventor: BERGSTROEM NIL EMIL LENNART
IPC: E04B9/30
Filed: 1965-09-17
Abstract: 1,159,804. Coating with pre-formed sheets. N. E. L. BERGSTROM. 19 Aug., 1966 [17 Sept., 1965], No. 39788/65. Heading B6G. [Also in Divisions B5 and E1] A method of covering a wall or ceiling of a room with a thermoplastic sheet by stretching and fixing the edges of the sheet, is characterized in that during the stretching and fixing the sheet is heated to a temperature of between 25‹ and 40‹ C. to provide a smooth flow of the plastic material during the stretching. Preferably the plastic sheet is made of polyvinyl chloride and is heated to between 30‹ and 35‹ C., but polyethylene sheet may also be used. In a preferred method, each of the opposite edges of a sheet 4 are wrapped around four sides of a hardboard fixing strip 5 to which it is secured by staples 6 at intervals along the length of the fixing strip. One fixing strip is then nailed to the ceiling to be covered, or to a suitable fixture (e.g. a batten) on the wall or ceiling. A metal tool 7 in the form of an asymmetrical beam has one longer flange 8 which is inserted between the sheet 4 and the top of the other fixing strip 5 with the fixing strip between the flange 8 and a shorter flange 9 of the tool. A number of hydraulic rams 10 (see Fig. 2), are used to force the fixing strip 5 towards a wall surface 11 to stretch the sheet. Each of the rams 10 has a channel 12 at its upper end which engages a flange 13 of the tool 7, and at its other end it bears against a rigid support 14 resting against an opposite wall surface 15 and the floor 16 of the room. The rams are supplied with air under pressure through hoses 17 from a pump 18. When the sheet 4 has been stretched sufficiently and the fixing strip 5 is appropriately positioned, staples or nails are driven upwards through the fixing strip 5 and through slots extending from the free edge of the flange 8 upwards into a timber or similar batten which has already been fixed to the wall or to the existing ceiling. These nails or staples are not driven right home until the tool 7 has been subsequently withdrawn from the batten 5. To enable the thermoplastic sheet 4 to flow and stretch evenly so that crinkles are eliminated and the batten 5 can easily be brought as close as necessary to the wall surface 11, the sheet is heated preferably to between 30‹ and 35‹ C. As shown in Fig. 2, a radiant heater 19 which burns liquefied gaseous fuel such as propane or butane, supplied to it through a hose 20 from a bulk container 21 on a portable trolley 22 may be used. In Fig. 3 (not reproduced), a hot air blower having an electrically operated fan and a burner unit supplied with propane or butane from a container may also be used. The dissipation of heat by radiation or convection is shown by the arrows. Thermometers suspended in the room adjacent to the ceiling may be used to monitor the temperature so that appropriate adjustments in the gas burning rate or fan speed can be made.

In a sodium cooled, fast reactor control is effected by movement of the reflector surrounding the core. The fuel assemblies are mounted in tubes having a hexagonal, tapered, crosssection and a twist along their longitudinal axes. The tubes are disposed together in a skewed arrangement to form a core having a minimum voidage and the upper ends of the tubes are widely separated to facilitate instrumentation. The reflector assembly, which is cooled, includes drums set round a core and rotatable about the vertical axes. Each drum is divided into vertical half-sections, one of which is a poison (B 4 C) and the other a reflector, and reactor control is effected by rotation of the drums to present the appropriate half-section to the core. Safety control elements are mounted between the control drums. Each control element is displaceable along a vertical axis and is formed with a reflecting lower half and a poison upper section. The fuel assemblies are formed of rods of stainless steel clad plutoniumdioxide stainless steel cermet supported in a steel tube which is mounted in and spaced from a hexagonal tube to permit coolant flow. A flat transverse temperature gradient is produced across each tube and thermal bowing is reduced.
