Title: Improvements in or relating to gas turbine engines
IPC: F02C9/18
Filed: 1969-10-17
Abstract: 1277075 Gas turbine engines BENNES MARREL 17 Oct 1969 [8 Nov 1968] 51033/69 Heading F1G The invention relates to a gas turbine engine of the kind having a compressor, combustion system and a turbine which drives the compressor also a separate power turbine, by-pass valves being provided which when open permit gases from the compressor drive turbine to pass direct to exhaust, the by-pass valves being loaded in the open direction by spring means and in the closed direction by pressure of air from the compressor. The engine shown comprises a compressor 3 from which air flows to an annular chamber 6, the air then passing to two combustion chambers 8 and thence through inlet guide vanes 11 to the compressor-drive turbine 4. The gases then pass through annular chamber 13 and guide vanes 14, 15 to the separate power turbine 16. The gases finally discharge through ducts 17 to exhaust duct 18. A series of by-pass valves 20 are provided which when open allow gases to pass from the compressor-drive turbine 4 direct to exhaust. Each by-pass valve comprises a valve member 22 and stem 23, a piston 26 being mounted on the stem. A spring 30 acts on the piston to hold the valve 22 open so that gases can flow as indicated by arrows 43. Air under pressure from the compressor 3 in the space 6 passes through opening 36 into the space 34 at the opposite side of the piston so that as the pressure of the air from the compressor increases, the piston 26 is moved outwardly against the force of the spring 30 thus causing the valve member 22 to engage against the seat 37 closing off the by-pass passage. The gases from the compressor-drive turbine thus pass to the power turbine 16 which acts to drive a load such as the drive shaft of a vehicle. In operation, air tends to leak past the piston 26, this air then flowing through the passage 35 through the valve stem so cooling the valve. In the embodiment, four by-pass valves 20 are provided.

Title: Scanning System.
IPC: G11B21/08
Filed: 1966-11-15
Abstract: 1,161,102. Scanning data stores; read-only stores. INTERNATIONAL BUSINESS MACHINES CORP. 15 Nov., 1966 [22 Nov., 1965], No. 51036/66. Headings G4A and G4C. A scanning system for reading data recorded on equally spaced tracks, includes servo-controlled scanning means which comprises a differential amplifier, the output of which is used to derive a feed-back signal indicating the degree of misregistration between the scan and the track being scanned, and scan shifting means selectively operable to apply a predetermined bias to an input of the differential amplifier whereby, under the control of the feedback signal thus generated, the scan is caused to shift to a different track. A photographic film bears digital data in parallel tracks, each binary digit being represented by a transparent area followed by an opaque area (for 1) or an opaque area followed by a transparent area (for 0). Each oddnumbered track is separated from the following track by an opaque strip and from the preceding track by a transparent strip. Light from a cathode-ray tube 20 scans along a track for data readout. Data and reference photomultiplier tubes 24, 25 receive the CRT light (in the former case through the track) and feed respective inputs of a differential amplifier 35 via a transistorized switch 31, which photomultiplier tube feeds which input being determined by whether an odd-numbered or evennumbered track is being followed. The amplifier output provides the data, and is also fed to an integrator 37 (or filter) to obtain a D.C. level which keeps the cathode-ray tube beam centred on the track. To change from one-track to the next (in either direction) the switch 31 is controlled to connect a selected one of the photomultiplier tubes to a selected one of the amplifier inputs, depending on whether the present track is odd or even numbered and on whether the preceding or following track is wanted. The other amplifier input is grounded. The reference photomultiplier 25 also controls the cathode-ray tube beam intensity. Changes relating to the data stored on the film 22 can be stored in a separate magnetic memory. The film could be moved instead of the beam. The film may be replaced by a thermoplastic or magnetic store.
