Title: Improvements in or relating to the formation of relief images for photographic and other purposes
IPC: G03F7/038
Filed: 1931-11-16
Abstract: A moulding surface is obtained by photographic or chemical processes, the surface being developed into relief by heat treatment.  A support is first coated with a layer containing one or more reducible metal compounds and at least 50 per cent of gelatin or equivalent colloid, a localized reduction being then effected either by light action or by printing, or the local application of a reducing agent, the layer being finally heated to cause the parts where reduction has taken place to swell into relief.  Reference is made to Specification 323,768, [Class 98 (ii), Photographic processes &c.], more especially as regards the colloid content of the layer.  The layer may contain a reducible metal compound and a substance having an acid reaction, or these may be combined as a metal salt of an organic acid.  Suitable metal salts are ferric and/or mercuric salts, or cobaltimine, and for the acid constituent salts, or cobaltimine, and for the acid constituent a soluble carboxylic acid or sodium acid phosphate. Three particular examples of compositions and processes are described. Reducing agents for localized application for ferric and mercuric salts are stannous salts or sodium or other sulphites.  For coatings containing mercuric salts a solution of ferrous sulphate containing potassium hydroxide may be used.  The height of the relief depends upon the thickness of the layer.  The effects on the relief of lactic acid and sodium acid phosphate are described.

Title: Refractory heat insulating materials
Inventor: CHAPPELL JOHN JOHNSON
IPC: F16L59/04
Filed: 1969-10-06
Abstract: 1,264,022. Thermal insulation. FOSECO INTERNATIONAL Ltd. 6 Oct., 1970 [6 Oct., 1969; 2 July, 1970], Nos. 49044/69 and 32217/70. Heading F2X. A refractory heat insulating material, suitable for the protection of turbine engine casings, is formed of a dry composition comprising inorganic refractory fibre and a water soluble inorganic binding agent, the composition being of a form of which the hardness, strength and density do not vary across the bulk material. Usually, though not necessarily, such a composition will be one in which the binding agent is homogeneously distributed. Preferably a wet or damp mixture of the ingredients is first formed and then dried by means of a drying method which does not cause migration of any of the components of the composition. Dielectric heating, infra-red heating or, preferably, microwave drying may be employed. The inorganic fibre is one or more of aluminosilicate, calcium silicate, asbestos, alumina, silica, zirconia and carbon fibres. The binding agent is silica sol, alumina sol, sodium silicate, potassium silicate, ethyl silicate or a metallic phosphate or borate. The composition may also include up to 10% by wt. of finely divided refractory material, e.g. alumina, silica, calcined rice husks, diatomite, kieselguhr, magnesia, silicon carbide, silicon nitride or fireclay. The insulating material may be faced or backed with a heat reflective layer such as aluminium foil, and it may if desired be faced with a refractory dressing. When used for lining turbine, aero engine or exhaust casings, the material may be secured in place by any convenient method such as adhesion, bolting or riveting, or by two or more such methods. A composite insulating material may be formed of two layers each of material according to the invention but of different densities. The lower density layer can even be honeycombed if desired. When used for lining a turbine or aero engine casing the lower density layer is preferably adjacent the casing. In a particular example, a preformed web of silica sol bonded aluminium silicate fibre, of thickness 25 mm., was adhered to the inside of a gas turbine casing with a sodium silicate based adhesive and riveted in place at the edges.

Abstract: 1,008,292. Air turbine driven compressor sets. BRISTOL SIDDELEY ENGINES Ltd. Oct. 2, 1964 [Aug. 15, 1963], No. 32353/63. Heading F1G. An air conditioning and circulating or compressing unit comprises a compressor, and first and second axial flow turbine assemblies the rotors of the compressor and turbine assemblies being directly interconnected so as to rotate as a unit. The first turbine assembly comprises two nozzle rings and associated sets of rotor blades arranged for the flow of actuating air therethrough in parallel, in opposite directions, and the compressor is of the centrifugal type and is suitable for the delivery of air to be conditioned through a heat exchanger to the inlet of the second turbine assembly, the conditioned air flowing from the outlet of the second turbine assembly. In the assembly shown, the centrifugal compressor is indicated at 2, the first turbine assembly at 1 and the second turbine assembly at 3. The first turbine assembly comprises two sets of inlet nozzle guide vanes 4, 5 through which air flows from the surrounding space which may be the cabin of an aircraft, in parallel, in opposite directions so as to act on the rotor blades 8, 9 of the first turbine, the exhaust air passing into the chamber 13 at reduced temperature. The air then passes through the duct 14 to a heat exchanger 15, Fig. 2 (where the exhaust air is utilized to cool air discharging from the compressor 2), the air finally discharging to atmosphere which is at a lower pressure than within the cabin. The turbine blades 8, 9 are mounted on a rotor drum 10 11, 12 the shafts 16, 17 of which are supported in bearings 18, 19 in stationary structure. The compressor impeller 22 is mounted at the right-hand end of the shaft 16 and takes in air from the aircraft cabin through inlet 23 and discharges it at increased pressure through volute 25. The air then passes through duct 26 to the heat exchanger 15 where it is cooled by the air discharging from the first turbine 1. The cooled air under pressure then passes through duct 34 into the inlet volute of the second turbine 3, the air being directed by inlet guide vanes 35 on to the rotor blades 36. The air finally discharges through outlet 38 at reduced pressure and temperature into the duct 39 where it passes together with fresh air drawn in from atmosphere through duct 40, into the aircraft cabin. The second turbine rotor blades 36 are mounted on a rotor 37 which is secured at the left-hand end of shaft 17. Lubricating oil is drawn into the bearing 18 from sump 20A through duct 30 by means of an impeller 31 ,  the oil returning to the sump through a drain passage 32. The bearing 19 is lubricated in a similar manner by means of impeller 46. Air from the volute 25 is tapped off through duct 48 and passed through air jackets 50, 51 around the chamber 13 and outlet duct 14 so as to prevent formation of ice therein, the air being discharged into the inlet volute of the second turbine 3.
