Title: Gas turbine ducted fan engines
IPC: F02K1/66
Filed: 1972-12-05
Abstract: 1364370 Gas turbine ducted fan engines - reverse thrust operation SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 5 Dec 1972 [7 Dec 1971] 55995/72 Heading F1J The invention relates to a gas turbine ducted fan engine in which the pitch of the fan blades 1a is reversible whereby the fan may be utilized to provide reverse thrust. The object of the invention is to ensure a continuing flow of air to the engine compressor when the fan blades are moved to reverse pitch. The engine comprises a fan 1, LP compressor 6, HP compressor 8, combustion equipment 9, HP turbine 10 and LP turbine 11. The fan is driven by the LP turbine through reduction gearing 15, and the pitch of the fan blades 1a is reversible by means indicated at 17. In normal operation air-flow from the fan is divided, one stream 5a passing to the core engine, the other stream 7a passing to the fan discharge nozzle 7. For reverse thrust operation, air enters the fan nozzle as indicated at 7b and is discharged forwardly from the fan as indicated at 3b. In accordance with the invention means are provided to increase airflow into the fan duct during reverse thrust operation and comprises a series of openings 19 formed in the wall of the fan duct 18, each opening having disposed therein a pair of shutters 20a, 20b which are movable between a closed position to prevent air-flow, and an open position to permit air-flow through the opening. The shutters 20a, 20b are angularly movable about axes (25a), (25b) respectively by means of a shaft 26 and gearing, the shafts 26 of all the openings being connected for simultaneous operation simultaneously with selection of reverse pitch of the fan blades. The shutters are formed with scoop members 32a, 32b which are directed forwardly when the shutters are moved to the open position, Fig. 4 so that airflow as indicated by arrow 34 at the lower part of Fig. 1 is re-directed as indicated by arrows 35 and 5b.

Abstract: 1,254,716. Semi-conductor devices. GENERAL ELECTRIC CO. 29 Nov., 1988 [1 Dec., 1967], No. 56905/68. Heading H1K. A method of embedding a semi-conductor chip in a dielectric layer comprises placing the chip on the layer, laying a sheet of metal over the surfaces, pressing a platen on to the metal sheet to force the chip into the layer until their surfaces are flush and then etching away the metal sheet. As shown, Fig. 1, the semi-conductor ship 1 is placed on the surface of a P.T.F.E. bonding layer 2 provided on a dielectric substrate 7 which may also carry contact members 8. The substrate is supported on a resilient pad 5 of silicone rubber placed on a bottom platen 6. A sheet 9 of aluminium or copper is placed over the chip and substrate and a top platen 10 having a highly polished lower face is brought into contact with the sheet. The bonding layer is softened by means of heaters incorporated in the platens 6 and 10 and pressure is applied to force the chip 1 into the layer 2 until their surfaces are level. The assembly is cooled and removed from between the platens. The metal sheet 9 which adheres to the bonding layer 2 is removed by etching. Initially the chip may be bonded to the surface of layer 2 which may be formed with a recess to help locate the chip. Conductive tracks may be deposited on the surface of the final structure to contact electrodes on the embedded chips and extend on to the surface of bonding layer.

Abstract: 1,267,754. Automatic control. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. Dec.24, 1969 [Dec.30, 1968], No.62903/69. Heading G3R. A digital computer which normally supplies the error signal in a closed-loop system controlling a variable also supplies a signal through a memory to a comparator in which it is compared with a signal dependent on the magnitude of the variable so that, if the computer fails, control of the variable continues without shock. In Fig.2, a signal 1, corresponding to the measurement at I n  of a variable of a production unit U, is applied to a digital computer C which compares it with a desired value so that any error produced at 2 is effective to control a valve V a  and thereby correct the variable. Signal 1 corresponding to the measured variable is also applied at 10 to a comparator R n . While computer C is in control, it also applies, through a memory M n  to the other input 14 of comparator R n , such a reference signal that the output of the comparator at 12 is equal to control signal 2. Then, if the computer fails, causing switches K 1  K 3  to change over, the control signal 12 initially applied to valve V n  is the same as that previously applied by the computer. Thereafter comparator R n  controls the production unit U and the desired value reference signal may be varied manually from the control desk P through line 6. Control desk P also serves for monitoring and controlling the computer C and the production unit U. In a modification (not shown), a plurality of production unit variables are measured and controlled in succession by a multiplex system involving a single computer associated with analogue-digital and digital-analogue converters, smooth changeover to standby comparators being provided for selected variables in the case of computer failure.
