Title: Improvements in gas turbine engine inspection apparatus
Inventor: BOURGEOIS HECTOR SEBASTIEN
IPC: F02C7/36
Filed: 1967-06-14
Abstract: 1,147,495. Turbines-inspection arrangements. GENERAL ELECTRIC CO. June 14, 1967 [Sept. 16, 1966], No. 27466/67. Heading F1T. A gas turbine engine comprises an outer casing and an inner casing in spaced relation thereto, the inner casing forming a wall of the turbine working fluid duct, the two casings being formed with radially aligned inspection ports; the ports are normally closed by means of a seal assembly comprising first and second relatively movable seal members which close the ports in the inner and outer casings, the first seal member and the port in the inner casing having mating seal surfaces, the sealing effectiveness between the parts being enhanced during engine operation by the differential pressure existing. In the engine shown the turbine assembly comprises rotor discs 29, 31 carrying blades 26, 28 at their peripheries, an inlet nozzle guide vane assembly 25, and an interstage guide vane assembly 27. The assembly comprises also an outer casing 14 and an inner casing formed by the guide vane outer shroud rings 36, 37 and the intermediate shroud rings 38, 39 which are disposed around the rotor blades 26, 28, all respectively. Inspection ports 45, 47 are formed in the shroud ring 37 and outer casing 14 respectively, the port 45 being formed by a bore in a boss 50 and being located between a pair of adjacent guide vanes 46, and the port 47 being formed in a boss 52 in the outer casing 14. The bores are radially aligned, and the bore 47 is screwed. The inspection ports are normally sealed by a composite seal assembly 60 which comprises a first seal member in the form of a plug 64 having a seal surface 63 which engages the seal surface of the bore 45. The plug 64 has an internal bore and a flanged head 71 which is located within a cavity 68 in the second seal member 62, the head 71 being retained therein by means of a snap ring 72. A spring 74 normally keeps the members 64, 62 apart but as the second member 62 is screwed into the port 47 so as to engage the seal ring 66, the part 64 moves relatively to the part 62 as shown. In operation, the air pressure prevailing in the space 20 is greater than the gas pressure within the working fluid duct 35, the pressure differential serving to retain the seal member 64 in good sealing contact with the surface 51. When the seal assembly is removed an inspection tool may be inserted through the ports to permit inspection of the blades.

Patent GB-278065-A (GB)
Abstract: 278,065. Rothm³ller, J., Leschanovsky, L., and Reiber, F. June 26, 1926. Supplying and controlling consuming devices. -A low-potential device, such as a bell, is supplied from high-potential mains through a series working resistance, a second resistance is connected in parallel with the bell for protective purposes, and a relay automatically inserts an additional series resistance when the bell is disconnected in order to reduce the current normally flowing through the parallel resistance. In the arrangement shown in Fig. 2, a weak current normally flows through a working resistance 19 (700 a high resistance 16 (24,000 ohms), and the winding 5 (200 ohms) of a relay which serve, as a protective resistance in parallel with the bell 35. The relay is energized by this current and opens the contact 8. When the switch 3 is closed, the bell is put in parallel with the relay 5, thereby reducing the current through the latter so that contact 8 is closed to shunt the resistance 16 by a low-resistance winding 38, thereby increasing the current through the hull. The contact 8 is held closed by the winding 36 until the switch 3 is opened; the winding 38 serves to neutralize any remanent magnetism. In the modified arrangement shown in Fig. 5, a weak current normally flows through a working resistance 30, a high resistance, 31, and a resistance 32 part of which serves as a protective resistance in parallel with the hell 35 when the latter is brought into circuit. The windings 24, 37 of the relay are normally without current. When the switch 3 is closed, current flows through resistances 30, 31, winding 24, contact 23, winding 37, bell 35, and switch 3 back to the mains. The attraction of the armature 21 opens this circut at contact 23, but closes a holding circuit through resistance 30, contact 25, mass of relay, winding 37, bell 35 and switch 3, the resistance 31 being shunted so that sufficient current flows to ring the bell.

In the process in which a positive print corresponding to a latent image in a silver halide emulsion layer is formed in a superposed layer by development of the latent image in the presence of a silver halide solvent and a fixed alkali, and migratory transfer and reduction of unexposed portions of silver halide, a volatile amine salt is provided in or adjacent to either or both of the layers, whereby high alkalinity may be maintained during development and transfer but the alkalinity may be reduced on separation of the layers by volatilization of free amine, and highlight stain in the print thereby avoided. Diethylamine sulphate is preferred as amine salt. Others are quoted. The developer may contain a thickening agent such as sodium carboxymethyl cellulose which tends to form a solid layer in the developing process and which layer may constitute a printreceiving stratum, or may be arranged to adhere to the photo-sensitive layer when the latter is separated from the superposed layer, which latter in this case provides the printreceiving stratum. A product for use in the process comprises a container releasably holding a processing liquid and a sheet support, the liquid containing the fixed alkali for use with processing agents present elsewhere, or containing also the processing agents, and if desired the thickening agent and nuclei for print formation as well; and the sheet support constituting or including the silver halide layer or the print receiving layer and having the amine salt distributed therein. The product is constructed generally of materials as described in Specifications 684,591, 703,231 and 714,412. Ammonium salts may be used instead of amine salts.

Title: A new or improved method and/or apparatus for ink setting in printing processes
IPC: B41F23/04
Filed: 1931-10-09
Abstract: A method of setting ink on a printed surface consists in subjecting the ink on the surface <PICT:0387763/III/1> <PICT:0387763/III/2> to the effect of heat and an electrical point discharge.  The discharge which serves to produce ozone, is obtained by a spark discharge from a series of points formed by a number of spiral springs 11 mounted on wires 12 all of which are connected to a conductor 10 mounted within an insulating holder 7 and to which is connected one terminal of a high voltage supply, the other terminal being earthed.  The apparatus for supplying heated air comprises electric heating elements 16 mounted within a burnished copper reflector 17, the air being directed past the heating elements on to the printed sheets &c. by a blower 19.  Both the heating and ozonizing apparatus are mounted on the reciprocating delivery mechanism 1 of the press and extend laterally across the sheets, so that during the delivery movement the sheet is subjected to the effect of heat and during the return movement of the carriage to the effect of ozone in a heated atmosphere.  The spark discharge serves in addition to neutralize any static electric charge on the paper but this may also be done by subjecting the paper to the action of a point discharge before the heat and ozonizing treatment.
