Abstract: 1327145 Packages E I DU FONT DE NEMOURS & CO 19 Jan 1971 [19 Jan 1970 30 Nov 1970] 2566/71 Heading B8C [Also in Divisions B2 and B5] A package comprises a container in the shape of a tube formed by sealing overlapping edges of a composite film, the container being sealed at the top and bottom to enclose the contents of the package, the composite film structure consisting essentially of a regenerated cellulose film, containing an anchoring agent, laminated directly to a biaxially oriented polyethylene terephthalate film, said composite film structure bearing on at least the cellulose film exterior surface a coating of a vinylidene chloride copolymer. In a preferred embodiment, a coating of the copolymer is present on both surfaces. The composite film structure may be made by conditioning a surface of the biaxially oriented polyethylene terephthalate film by an electric discharge, laminating the conditioned surface directly to a regenerated cellulose film containing an anchoring agent by passing the films between rollers and coating at least the cellulose film surface of the resultant laminate. At least one of the rollers may be heated. The film may be conditioned while passing over a heated roller. Coating may be effected by running the laminate through an organic solvent solution of the copolymer. In an alternative embodiment, the conditioning is effected by a flame treatment. Specified anchoring agents are polyalkyleno imines and thermosetting resins e.g. ureaaldehyde resins, melamine-aldehyde resins, melamine-urea-aldehyde resins, melamine-formaldehyde-polyalkylene polyamine resins, guanidine-urea-aldehyde resins, guanidine-carbamidealdehyde resins and mixtures thereof. Specified vinylidene chloride copolymers are copolymers of vinylidene chloride with acrylic or itaconic acid and with at least one other monomer copolymerizable therewith e.g. acrylonitrile, a C 1  to C 18  alkyl ester of acrylic or methacrylic acid, phenyl methacrylate, cyclohexyl methacrylate, p-cyclohexylphenyl methacrylate, methacrylonitrile, methyl vinyl ketone and vinyl chloride. The vinylidene chloride copolymer may be admixed with behenic acid, a slip agent e.g. finely divided magnesium silicate, bentonite clay or mica and waxes e.g. a glyceride ester, a microcrystalline wax, a paraffin wax or a high molecular weight amide.

Abstract: 807,906. Blind riveting. HUCK MANUFACTURING CO. Jan. 24, 1957 [April 6, 1956], No. 2587/57. Class 83 (4). [Also in Group XXV] A blind rivet comprises a pin 7, Fig. 1, with a head 8 and a shank including a locking-groove 13 and break-neck 14, a filler sleeve 20 and an expanding sleeve 18 surrounding the pin with sleeve 18 adjacent the head 8. Sleeve 20 has a head 21<SP>1</SP> at its end remote from head 8 containing a space 22, and a locking collar 24 adapted to be forced into said space when the groove 13 and the space are aligned. To set the rivet, the pin is pulled, by a device engaging serrations 17, causing sleeve 18 to engage the undercut surface 9 of the head 8 and to expand over the tapered end of sleeve 20 into engagement with, e.g., the face of a panel 4 which is being joined by the rivet to a panel 5. Continued pulling then shears the flange 25 from collar 24, forces the collar into space 22 and breaks the pin at neck 13, as shown in Fig. 5. The head 21<SP>1</SP> may be either raised or countersunk. In a modification the end 34, Fig. 8, of sleeve 33 remote from head 8 has a reduced outside diameter, so that when the rivet is set the sleeve is deformed as shown.

Title: Improvements in or relating to gas-turbine engine fuel systems
Inventor: LOMBARD ADRIAN ALBERT
IPC: F02K1/16
Filed: 1948-01-28
Abstract: 641,910. Gas turbine plant for jet propulsion of aircraft. ROLLS-ROYCE, Ltd. Jan. 28, 1948, No. 2608. [Class 110(iii)] [Also in Group XXXV] Ina gas turbine plant with re-heating, the fuel supply to the re-heat chamber is governed to maintain a constant temperature at a point up-stream from that chamber. In the jet-propulsion plant of Fig. 1 the discharge from a turbine 13 is re-heated in front of the propulsion nozzle 18 by burning fuel directed up-stream from burners 23 towards baffles 24. The exhaust unit may be increased in diameter at the re-heat portion to reduce the gas velocity in that region. The supply of fuel to the burners 23 is regulated by a valve 34 operated by a motor 38 under the control of a thermometric device 35. Fuel is supplied to the combustion chambers 12 by a pump 25 through a hand throttle 28. The propulsion nozzle has obturating flaps 19a which are brought to the dotted line position, when the exhaust is re-heated, by a motor 20 operated by air from the compressor under control by a hand-operated valve 22. The thermometric control may be transferred to the main fuel supply when reheating is not in operation. The fuel supplies to the combustion chamber burners 15, Fig. 2, and to the re-heat burners 23 are controlled by valves 51, 34 operated by motors 52, 38 which are alternatively connected to the thermal control circuit by a change-over switch 56. This switch normally connects the thermal control to motor 52. When the hand-operated throttle 27 is fully open, an arm 28b closes a switch 50 and a solenoid 58 is energized to move the change-over switch 56 to disconnect the motor 52 and connect the motor 38. 'Thereafter the thermal control governs the supply of fuel to the re-heat burners 23. Solenoids 61 and 62 are in circuit with solenoid 58 and, with the change-over, the circuit of ignition means 64 in the re-heat chamber is closed and the flaps 19a are moved to open the propulsion nozzle fully. The temperature sensitive device may be a thermo-couple connected to a standard E.M.F. and feeding a discriminating device 36. The output from the device 36 is led to an amplifier 37 supplying the motors. The temperature sensitive device may be a resistance thermometer included in one arm of a resistance bridge with an A.C. supply and the variations in phase may be used to control the motors. The thermal control may be used only to prevent excessive temperature. For this purpose the temperature sensitive device may be a thermo-couple, the output voltage of which is matched against a standard E.M.F. and an excess of its voltage used, through an amplifier, to control a throttle-valve or a fuel byepass valve. Several thermometric devices arranged in a ring about the exhaust unit may be used to give a mean temperature result for the throttle control.
