Title: Stator assembly for a turbine or the like
IPC: F01D9/04
Filed: 1967-11-13
Abstract: 1,135,349. Turbines. UNITED AIRCRAFT CORP. Nov. 13, 1967 [Nov. 23, 1966], No. 51611/67. Heading F1T. To facilitate removal of the guide vanes in a turbine or the like, e.g. the turbine nozzle guide vanes in a gas turbine engine, the individual vanes 24 are connected to an arcuate segment 30 of a split retaining ring by pins 32, the ring being removably mounted within the machine outer casing 22. In the assembled state, shown in Fig. 3, the pins 32 also engage an annular support member 50 carrying a seal 42 and bolted at 52 to an inner casing 54 itself bolted at 56 to the outer casing 22 and an annular member 58. The radially outer platforms 34 on the vanes 24 are thus held in position. An inner platform 62 on each vane is joined by a spline connection 64 to an annular member 66, in turn connected through a spline 68 to an inner support 70 bolted at 72 to a casing 76. An additional support member 78 has a lug 90 engaging a finger 82 on the platform 62 to limit radially outward movement of the vane 24 should the support structure at the outer end of the vane fail. A similar finger 80 adjacent the leading edge of platform 62 engages between lugs on member 66. The latter carries an annular shield 92 to prevent a bolt 72 from entering the gas stream should the bolt fail. To remove the guide vane assembly, bolts 60, 56 and then 52 are removed so that casings 22, 54 and member 50 can be slid to the left into the position shown in Fig. 5. The vane assembly is then moved to the left to disengage splines 68 so that the assembly can be moved radially outwards to the position shown dotted. A stator shroud ring 96 surrounding the rotor blades 26 can now be removed if required. The construction also permits removal of the guide vanes 24 individually rather than as a complete segment. The vanes are hollow to receive cooling air from a manifold 36 supplied with the air through passages 40 in the pins 32.

Title: Lithographic printing plates
Inventor: SORKIN JACK LEON
IPC: B41N3/03
Filed: 1965-12-08
Abstract: A metallic lithographic plate having a hydrophilic surface coating thereon ready for the reception of a light sensitive material, is prepared by hydroxylating the surface of a metal plate e.g. aluminium or zinc, by treatment with a hydroxylating agent, applying to the hydroxylated surface a solution of a metal ester of the formula (RO4)M in an organic solvent, R being an aryl hydrocarbon radical e.g. phenyl, tolyl or xylyl, or a C1-C8 aliphatic hydrocarbon radical e.g. an alkyl, isoalkyl, alkylene, isoalkylene, alkenyl or isoalkenyl radical, and M is titanium or zirconium, removing the solvent to deposit a film of the ester on the hydroxylated surface, and allowing or causing hydrolysis of the deposited film short of conversion to the metal oxide while simultaneously reacting the film with the hydroxylated surface.  The metal surface may be hydroxylated by treatment with an aqueous solution of sodium, potassium or ammonium hydroxide or of an amino alcohol, with boiling water for a period of 5 to 15 minutes, with strong oxidizers in the presence of water, or with a solution comprising sodium fluoride, aluminate and hydroxide. The metal ester may be applied in a humectant or hygroscopic solvent. The organic solvent, examples of which are given, may contain from 0.1 to 10% by weight of the ester, tetraisopropyl titanate being preferred.  After applying the ester solution, the plate may be dried by heating to a temperature of 150 to 180 DEG C for 4 to 7 minutes. The deposited film may be caused to hydrolyse by exposure to a moist-atmosphere.  The plate may be heated while exposed to the atmosphere to promote continued reaction of the film with the hydroxylated surface.  A layer of light sensitive material e.g. a diazo compound, bichromated albumen, casein, gum arabic, gelatin, glue, or a copolymer of vinyl methyl ether and maleic anhydride, may be applied e.g. by roller coating, dipping, or spraying, to the coated metal plate to produce a sensitized lithographic printing plate.  The metal ester solution may be applied by dipping, spraying, roller coating or whirling.

Abstract: 1445454 Cathode-ray tube RCA CORPORATION 9 Nov 1973 [13 Nov 1972] 52142/73 Heading H1D The viewing screen of a cathode ray tube, which screen is provided with a light reflecting metal layer, is made by preheating the metallized screen, and depositing upon the metal layer a coating of an organic, volatilizable filmforming material, to prevent the penetration of carbon particles into and through the metal layer, and thereafter depositing an overcoating of carbon particles; and baking the screen in air at about 400 to 450‹C to remove organic and volatile matter, the overcoating, and preferably also the coating, being chosen substantially free from substances which, when incinerated, produce alkali metal or alkaline earth metal ioncontaining residues, thereby to reduce the subsequent occurence of humidity-induced areas of reduced reflectivity. As described, an aluminized screen, preheated to about 85 to 95‹C, is sprayed first with a coating of acrylic resin or polystyrene emulsion, and then with colloidal graphite and/or carbon black suspended in deionized water, toluene, or xylene, with polyvinylpyrrolidone, ethylcellulose, polyvinyl alcohol, or carboxyl methyl cellulose, as dispersant and binder. The aluminum layer may be 2,000 to 3,000 Šngstr÷ms thick, and the carbon overcoating, which may be employed to absorb heat or to reduce secondary electron emission and electron scattering, may be 2,700 to 3,700 Angstr÷ms thick. Humidityinduced defects may be further reduced by spraying the aluminium which extends over the faceplate sidewall with a protective coating of fumed silicon dioxide. Reference is made to the application of the method to the screens of shadow-mask and block-matrix colour tubes.
