Title: Improvements in and relating to turbine and axial flow compressor rotor blades
Inventor: BRIDLE EDGAR ALFRED
IPC: F01D5/32
Filed: 1955-06-28
Abstract: 799,203. Turbine and compressor blades. PARSONS & MARINE ENGINEERING TURBINE RESEARCH & DEVELOPMENT ASSOCIATION. March 28, 1956 [June 28, 1955], No. 18656/55. Class 110 (3). In a bladed turbine or axial-flow compressor rotor in which blades a and packing pieces c are mounted in a serrated circumferential groove e formed in the rotor, no filling aperture or gate is provided, the blade roots and packing pieces being entered radially into the groove and then partially rotated about their axes, as shown in Fig. 3, so as to bring their serrated ends b into engagement with the serrations in the circumferential grooves. The final gap is filled by inserting in the radial direction the portions of a composite packer, the portions of which are held in position by self-locking means. The composite packer comprises three portions f, g, h, Fig. 8, the two outer portions g, h being serrated and the central portion f being wedgeshaped, the depth of the packer being less than that of the rotor groove. A number of the blades and packing pieces adjacent the final gap are also of reduced depth and a flat spring k is disposed in the space beneath the blade roots, packing pieces and composite packer, the spring acting to hold the wedge portion f outwardly in engagement with the portions g, h. The wedge portion f is held outwardly by centrifugal force during rotation of the rotor. In a second arrangement only the central portion of the blade roots and packing pieces is of reduced depth, the spring k being of less axial width than that shown in Fig. 8. The outer portions g, h of the composite packer may have shoulders which engage recesses in the surface of the rotor so as to lock the blade assembly against circumferential movement. Instead of a single composite packer, a number thereof may be used, the final gap being divided into a corresponding number of separate gaps spaced round the periphery. Specification 639,320 is referred to.
Patent GB-1305772-A (GB)
IPC: C08J7/043
Filed: 1970-04-20
Abstract: 1305772 Laminates BOSTIK Ltd 20 April 1970 [21 April 1969] 18718/70 Addition to 1236043 Heading B5N [Also in Division B2] The surface of a first substrate is prepared for bonding to a second substrate by means of adhesive by subjecting the surface to ultraviolet radiation and applying polyisocyanate to the surface, the first substrate being of a composition comprising photosensitizer material and polymeric material having a critical surface tension at wetting of not more than 35 dynes per centimetre, polymer molecules of the polymeric material having at least one hydrogen atom of a carbon chain of a repeating unit of the polymer molecule. The photosensitizer may be a halogenated hydrocarbon, e.g. methylene chloride, trichloroethylene, chloroform, a ketone, e.g. benzophenone, acetophenone, benzoin, 2-acetonaphthene, or acenaphthene or fluorene. It is stated that the photosensitizers are grafted into the molecular chains of the polymer molecules of the substrate and provide groups which react with isocyanate. The photosensitizer may be distributed in the composition of a substrate, e.g. by milling. Residual photosensitizer may be wiped off the surface after radiation. The polymer of the first substrate may be polyethylene, polypropylene, copolymers of ethylene and propylene alone or with a minor amount of non- conjugated diene, e.g. 1.4 hexadiene, fluorinecontaining polymers, e.g. polyvinyl fluoride, polyvinylidene fluoride. Preferably the radiation step is carried out before the polyisocyanate is applied. Preferred polyisocyanates have NCO functionality of more than two, e.g. triphenyl methane triisocyanate, polyarylene polyisocyanate-NCO functionality 2.8, applied from solution in volatile organic solvents. The adhesive may be applied to the surface after the application of polyisocyanate or, alternatively, the polyisocyanate may be applied after the radiation step in admixture with the adhesive. Suitable adhesives are solutions of linear polyester glycol urethanes, polyether glycol urethanes, linear polyesters. The adhesive may be solvent- or heat-activatable. In an example a milled mixture comprising ethylene-propylene-diene terpolymer, zinc oxide, stearic acid, carbon black, aromatic processing oil, mercaptobenzothiazole, dipentamethylene thiuram tetrasulphide, tetramethylthiuram disulphide, sulphur, tellurium diethyl dithiocarbonate, benzophenone was cured under pressure and sections of the cured resin subjected to ultra violet irradition and thereafter wiped with a solution of polyarylene, polyisocyanate in methylethyl ketone. The surfaces were then coated with an adhesive composition comprising N-tetrahydrofuran, a copolyester obtained by condensation of terephthalic acid, hexahydrophthalic anhydride and sebacic acid with cyclohexane dimethanol and butane diol. After drying the adhesive was heat-activated and surfaces of pairs of the sections pressed together.

Patent GB-193002-A (GB)
Abstract: 193,002. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Benson, W. A.). Feb. 11, 1922, [Convention date]. Semi - automatic exchange systems. - An alarm switch B is provided at a private branch exchange which operates in the event of a fault thereat to find an idle line and to give a distinctive signal to the main exchange according to the nature of the fault. Two contacts are provided, one 3 being closed in the case of the blowing of a fuse and the other 2 in the case of minor troubles. Upon closing of the contact 2 for example, a relay 7 is energized, connecting up the rotary magnet 13 and a switching relay 12, which coact in the usual manner to find an idle line 46, 49. The switching relay 12 also operates a slow-to-energize ring- ing relay 14, which connects the generator G to the line, operating a drop signal at the main exchange. At the same time, a circuit is closed for a relay 8 of the type described in Specification 156,076, having a vibrating weight attached to one of its contact springs, so that a dependent high-impedance relay 9 only energizes after an interval, and disconnects the generator G. The operator now inserts the answering plug of an idle cord circuit, causing the energization of relays 10, 11 in turn, and when the listening key is thrown she hears the minor-trouble signal transmitted from an induction coil 53. Upon removal of the answering plug, the relay 10 de-energizes, but the slow relay 11 remains energized long enough to complete a circuit for a relay 4, which locks itself and remains energized until the fault is cleared, and initiates the release of the switch B, leaving the line 46, 49 idle. If the contact 3 becomes closed, a relay 6 is energized, which acts in a similar manner to the relay 7, a relay 5 being maintained energized until the fault is cleared, and the signal being given by an induction coil 52. If both the contacts 2, 3 become closed, the arrangement is such that the relay 6 is effective.
