Title: Improvements in and relating to electric ship propulsion systems
IPC: B63H23/24
Filed: 1929-07-06
Abstract: 332,418. British Thomson-Houston Co., Ltd., and Watson, G. O. July 6, 1929. Dynamos and motors combined for transmitting power.-In a ship propulsion system employing a number of motors which may be driven each from a separate generator or all from a single generator, and having switch interlocks preventing paralleling of the generators, each switch operating member 10 - - 12 has a notched sector 19 - - 21 co-operating with a locking segment 31 - - 33 and the locking segments are fixed upon a common shaft 23. In a system having two motors and two generators, with an isolating switch between each motor and its generator, and a tie switch between the motors, the arrangement prevents the tie switch being closed when both isolating switches are closed, or the closing of a second isolating switch when a tie switch and one isolating switch are closed. The three switches are in cubicles, and the shaft 23 is provided with further locks 34, 35 co-operating with the keys 36, 37 of the cubicle locks, so that the switches cannot be operated until the cubicles have been closed. To prevent a change in circuit connections unless the field and reversing levers are in their off positions, a shaft 22, with interlocking segments 24 - - 26 engaging the sections 19 - - 21, is provided with a lock 27 co-operating with a key 29 of locking mechanism shown in Fig. 6. The field control lever, which may also control the loading of the governor over a portion of its stroke, is connected to a bar 58, a slow speed lever is connected to a bar 59, and the reversing lever to a bar 60. Notches in these bars co-operate with projections on transverse locking bars 61, 62, 67. The field control lever therefore cannot be operated unless the reversing lever is definitely ahead or reverse, and the latter lever cannot be moved until the former is in its minimum position. The slow speed lever cannot be moved unless the field control lever is in position giving minimum speed setting of the governor, and the latter lever cannot be moved to increase speed unless the former is in its maximum speed position. The member 67 carries a notch 70, co-operating with a Castell lock 69 operated by the key 29, so that that key can only be removed from the lock when this is engaged, that is to say when the member 67 is in a position locking the field lever in its minimum position and the reversing lever in its off position.

Abstract: 1336287 Electronic fuel injection systems for I C engines GENERAL MOTORS CORP 1 June 1972 [11 June 1971] 25711/72 Heading G1N In an 8 cylinder I.C. engine fuel injection system, eight injectors are sequentially energized in each engine cycle by pulses triggered in synchronism with engine rotation, the pulses having a duration dependent upon at least one engine operating parameter (e.g. intake pressure, throttle position), and the system being arranged such that overlapping time relationship of pulses supplied to successive injectors is possible. As shown in Fig.2, a rotor 26 having a pair of magnets 30a, 30b is rotated with the engine relative to a stator 28 provided with four coils 32a-32d, the magnet 30a inducing the pulse pairs 34 and the magnet 30b inducing the pulses pairs 36, Fig.3 in the respective coils. As shown in Fig.5, each coil is connected to a respective flip-flop 38a-38d producing respective outputs A 1 -A 4 , Fig.6, in response to the pulse pairs 34, 36. The outputs A 1  and A 3  are applied to a multiplexer 40a which provides a timing signal C 1 , and the outputs A 2  and A 4  are applied to a multiplexer 40b which provides a timing signal C 2 . The timing signals C 1  and C 2  are applied to a multiplexer 54 which provides a single timing signal E having eight level transitions per engine cycle corresponding to initiation of direction in respective cylinders. A controller 20 receives the timing signal E and in response to each level transition provides a pulse to produce a pulse train F, Fig.7, the duration of each pulse being one quarter of the desired injection pulse duration, determined by the engine operating parameter. A separator 62 is responsive to the pulse train F and the signal E to provide a pair of pulse trains G 1  and G 2 . A pair of separators 68a and 68b are respectively responsive to the pulse train G 1  and the timing signal C 1  and the pulse train G 2  and the timing signal C 2  to provide a set of pulse trains H 1 -H 4 . Multipliers 78a-78d are respectively responsive to the pulse trains H 1 -H 4  to extend the duration of each pulse by a factor of four, to provide a set of pulse trains H 1 '-H 4 '. Separators 80a-80d are respectively responsive to the pulse trains H 1 '-H 4 ' and to the timing signals A 1 -A 4  to provide a series of eight pulse trains I 1 -I 8 . These pulse trains are respectively applied to injectors V 1 -V 8  via amplifiers P 1 -P 8 . The pulses F may have a duration which is any fraction, provided the maximum duration does not exceed one-eighth of an engine cycle, of the desired injection duration, the multipliers then multiplying by the corresponding factor. The transducer shown in Fig.2 may be modified by replacing the coils with Hall effect resistors or any suitable electrodmagnetic signal generating devices. It may be entirely replaced by a mutiple contact relay switch or a photo-electric transducer. (For Figures see next page)

Filed: 1955-09-12
Abstract: 812,411. Gas and steam-turbine plant. HENSCHEL & SOHN G.m.b.H. Sept. 12, 1955 [Sept. 10, 1954], No. 26019/55. Class 110(3) Also in Group XII] Steam generated in cooling the rotor and blades of a gas-turbine together with steam generated by cooling the combustion chamber, inflow housing and gas-turbine casing is superheated by the combustion gases in a superheater arranged within the combustion chamber between its burner zone and the inlet of the gasturbine and then used in a turbine on the same shaft as the gas turbine. Air compressed in the compressor 30, Fig. 3, is cooled in an intermediate cooler 32 and further compressed in a compressor 33 which discharges through a heat exchanger 35, 36, 37 to the lower part 1 of the combustion chamber. The middle part 7 of the combustion chamber is bolted to the lower part 1 and is followed by the upper part 18. The gas-turbine housing 23 is connected to both parts 7, 18. The turbine exhaust gases pass through the heat exchanger to atmosphere or to a feed-water preheater (not shown). Steam generated in the cooling jackets of the combustion chamber is passed into a superheater located in the lower part 1 of the combustion chamber and then fed to the steam turbine 21 which discharges to a condenser (not shown). The steam turbine is coupled to the gas turbine 23, the compressors 30, 33 and an electrical generator 52. The arrangement of the gas and steam turbines and combustion chamber is shown in Fig. 1. Air from the compressor is supplied through the conduit 4 and fuel burnt therein by means of numbers of tangentially disposed burners 3. The combustion gases pass through the superheater 6 to the inlet housing 27 of the gas-turbine. The lower part of the inlet housing 27 is integral with the middle part 7 of the combustion chamber which is mounted by brackets on the foundations so that the supporting surfaces of the brackets lie in a horizontal plane through the axis of the inlet housing. Steam generated in the water-cooled turbine rotor 13 and blades 14 is led through the shaft 12, gland 15 and conduit 16 to the steam-collecting chamber 17 in the upper part of the combustion chamber. The gas-turbine housing 23 is surrounded by a cooling jacket 25 which is connected to the upper part 18 of the combustion chamber 1 by a conduit 26. The combustion chamber is surrounded by a cooling jacket 2 which may be formed by a plurality of small diameter tubes lying side by side. Steam from the collecting chamber 17 passes through the superheater 6 to the steam turbine 21. When the load on the plant is reduced, the fuel supply is reduced. To maintain, under these conditions, the load on the gas turbine additional fuel may be introduced into the combustion chamber between the superheater 6 and the inlet to the gas turbine. Air branched off after the heatexchanger may be introduced into the cornbustion chamber with this fuel.

Title: Multistage detection of velocity estimation from seismograms
IPC: G01V1/30
Filed: 1972-06-06
Abstract: 1363383 Seismic signal processing MOBIL OIL CORP 6 June 1972 [29 July 1971] 26310/72 Heading H4D  Velocity data are computed automatically from a set of seismic reflection traces by a twostage method, the first stage comprising searching the traces at instantaneous values of trace time to determine estimates of the reflection times and of acoustic velocity, the second stage comprising searching the traces within time windows at the estimated reflection times to determine velocity within a velocity range centred on the estimated acoustic velocity. In one embodiment an input common depth point (CDP) set of digitized traces is searched along assumed normal moveout (NMO) curves as in Specification 1,304,248 (Division H4) to determine the estimated times T N  and velocities V N  of successive reflections. This is the first stage and is denoted by steps 20 to 36; it is repeated for each CDP set. Estimated velocity is plotted as a function of trace time T and horizontal distance X along a survey line. In the first stage search the trace amplitude values across a CDP set, at trace times lying on an assumed NMO curve, are noted and summed at 33. Each sum exceeding a threshold α is stored at 37 to derive a respective amplitude sumversus-time trace for each CDP set. At 38 a search is made across these traces, along assumed dip lines, to determine the dip D N  of each subsurface reflector. In the second stage a time window of duration corresponding to the expected length of a seismic wavelet is selected at 48 at a time tx on each trace of a CDP set, values of tx being calculated at 47 relative to a selected reflection time T FIRST  so as to take into. account set-to-set dip and trace-to-trace moveout (dependent on an assumed velocity V FIRST  in a range centred on the estimated velocity V N ) across the set. The signal in each window is detected at 49 by, e.g. a summation of amplitudes or by a zero-lag cross-correlation of window pairs, the correlation products being summed to give at 50 a measure of signal power. By iteration, the signal power for other assumed velocities within the range is determined and the assumed velocity giving the maximum power is stored at 53 as being the best estimate V NEW  of the actual velocity. Steps 47 to 53 are iterated for other estimated reflection times T N .
